Predominant Vacuum Technology

SecoVac 01

Vacuum switching technology is nowadays the dominant switching

principle in medium voltage. Innovative developments are leading to a

continuously increasing market growth, based on the fundamental

advantages such as reliability, availability, compactness and, last but not

least, the envi ronmental friendl iness of the vacuum as a switching

medium.

Vacuum Interrupter

The switching element of the vacuum circuit-breaker is the vacuum

interrupter. It consists of an arc chamber, which is located between twoceramic insulators. Terminal studs connect the contacts to the external

terminals. One contact is fixed within the housing, the other one is

moveable. The metal bellows enable the contact movement and provide a

hermetic connection to the interrupter housing. The contact stroke is only

a few millimeters. The internal pressure in the vacuum interrupter is less

than 10-7 bar. The vacuum circuit-breaker has no arc-quenching medium.

The properties of the contact material and the contact geometry define

the switching behavior and the switching capacity.

After contact separation, the resultant arc evaporates contact material

from the contact surfaces. The arc current thus flows throw a material

vapour plasma until the next current zero. Near the current zero, the arc is

extinguished, and the metal vapour looses its conductivity within a few

microseconds as a consequence of the recombination of the charge

carrier ions. In this way, the contact gap is de-ionized and the dielectric

strength restored very fast. The metal vapour condenses on the contact

surfaces. Only a very small portion condenses on the arc chamber wall.

The arc chamber wall has the function of a vapour shield, to prevent

condensation of the metallic vapour onto the insulators

Automatic Pressure Gelation

A special cushion layer made of high insulation, gas tight and strong elastic

material was employed around the surface of the ceramic tube of vacuuminterrupter before it was embedded, so the cracking is thoroughly avoided.

SecoVac is the first completed series MV embedded pole vacuum circuit

breaker in the world which employs the latest and mature technology of

Automatic Pressure Gelation (APG) to embed the vacuum interrupter and

connection terminals within epoxy resin. Compared with complete air

insulated vacuum circuit breaker or assembly pole vacuum circuit

composite insulation, SecoVac is of solid insulation, on one hand, the risk of

insulation fault caused by adverse operating environment such as dust,

humidity and small animals are eliminated thoroughly, so SecoVac is a

vacuum circuit breaker with high environmental resistance. On the other

hand, thanks to the embedded pole design, the distribution of electrical

field of the pole is much even than that in the assembly pole vacuum

circuit breaker, so the insulation strength is improved dramatically.

Embedded poles

Vacuum interrupter has extremely high internal dielectric strength

resulting from the ULV while the external dielectric strength is however

limited by the insulation capacity of the air, therefore also requires

embedding the chamber in a solid material, In such cases, the vacuum

interrupter is additionally well protected against external mechanical

influences such as impacts.

The main advantages of embedded poles are high dielectric strength

without additional external compensation in air, usability in an extremely

wide range of climatic conditions, and good protection of the vacuum

interrupter from dust, mechanical impacts and moisture. On the operating

mechanism side, it is equipped with modularized, standardized and

simplified spring mechanism, the whole spring mechanism is made up of

separated closing and opening modules which can be preassembled and

easily replaced on-site of end-users without any changing of the original

dynamic characteristic of the breaker, so the lead time for delivery and

down time for maintenance will be shortened.

SecoVac series MV embedded pole vacuum circuit breaker uses the latest and mature technology of Automatic Pressure Gelation (APG) to embed the vacuum

interrupter and connection terminals within epoxy resin. The vacuum interrupter is cast in the epoxy resin, so inside the epoxy resin there is no screw fixation

that will cause the concentrated harsh electrical field inside the epoxy resin and will consequently result in decrease of the electrical insulation strength of the

pole. Thanks to the embedded pole technology, the assembly of the pole is simplified, and the assembly accuracy as well as quality of the embedded pole is

easily to be controlled by the state of the art production process. The embedded pole technology also obviously improve the environmental resistant

capability of the breaker, as the primary circuit of the breaker is completely embedded inside the epoxy resin, the risk of insulation fault caused by adverse

operating environment such as dust, humidity, ingression of small animals, polluted ambient and high altitude operating site are eliminated thoroughly.

The key know how of the embedded pole technology is the buffering layer between

epoxy resin and ceramic housing of vacuum interrupter, the material and processing

of the buffering layer is essential to ensure the integrity of epoxy resin of the

embedded pole provide adequate adhesion between each other in any circumstance.

Our patented LSR (Liquid Si licon Rubber ) buffering layer and double APG (Auto

Pressure Gelat ion) process adopted in the produc ing of the embedded pole

thoroughly eliminates the cracking of the epoxy resin caused by the large difference

of thermal expansion coefficient between epoxy resin and ceramic in case of rapid

changing of the ambient temperature. APG process for LSR buffering layer ensures

that there will not be any air gap or bubble between the buffering layer and ceramic

housing, hence, the high electrical insulation strength of the embedded pole of

SecoVac series MV embedded pole vacuum circuit breaker is guaranteed.

The partial discharge value of embedded pole manufactured by our patented LSR

(Liquid Sil icon Rubber) buffering layer and double APG (Auto Pressure Gelation)

process is below 5pc with an applied testing voltage of 1.2Um.

Modular Operation Mechanism

SecoVac series MV embedded pole vacuum circuit breaker is equipped

with modularized, standardized and simplified operating mechanism, the

mechanism consists of separated closing and opening modules, all the

mechanical parts of the mechanism are integrated into these two modules .

The closing and opening modules are universal to whole series of SecoVac

embedded pole vacuum circuit breaker regardless of ratings, it means

there is only one kind of closing and opening module for the whole

SecoVac products family, thanks to such a design, the maintenance time

and cost for the mechanism is low, the replacement of modules can be

easily carried out on site. There is no impact on the original dynamic

characteristic of the breaker after the replacement of modules, so the

retest of the breaker is not required after the replacement of modules.

Another feature of the operating mechanism of SecoVac series MVembedded pole vacuum circuit breaker is that the total number of parts of

the mechanism is reduced compared with the traditionally designed

mechanism, so that the reliability of the mechanism is enhanced

significantly.

The opening damper of the mechanism plays a very important role to

ensure reliable performance and high mechanical endurance of SecoVac

series MV embedded pole vacuum circuit breaker. By adoption of the

opening damper, the overtravel and re-bounce of moving contacts of

vacuum interrupters during the opening of this VCB is reduced to a

minimum. The lower overtravel of the moving contacts means lower

mechanical stress to the bellow of the vacuum interrupter, so the designed

mechanical endurance of the vacuum interrupter is guaranteed. The lower

re-bounce of the contact ensures low arc re-striking probability during the

breaking of capacitive current, so the occurrence rate of operating

overvoltage is reduced. By the contribution of the opening damper,

SecoVac has successfully passed type tested as Class C2 breaker in

accordance with IEC standards.

The State of the art Processing and Advanced Quality Control

The high quality of the embedded pole is achieved by using the latest APG (Auto Pressure Gelation) technology and advanced vacuum mixing and degassing

technology that are carried out by the equipment. The Vogel clamping machine is an essential piece of equipment to ensure the mechanical and insulating

strength of the embedded pole of SecoVac series MV embedded pole vacuum circuit breaker.

As well as the processing facilities, the testing facilities are also very important to the quality control of the breaker. In the manufacturing process of SecoVac

VCB, from incoming material quality control to the final inspection and testing, every step is strictly calibrated and tested by means of testing facilities.

For every embedded pole, before it goes into the breaker assembly line, it shall go through following inspections and testing carried out in factory:

Front Panel

This front panel fits into a collar-frame in the equipment when the breaker

is in the CONNECT position. It provides a metal barrier between the

breaker compartment and the secondary device compartment. Well

marked and easy-to-read operating controls and indicators include TRIP

button, CLOSE button, OPEN/CLOSE indicator, CHARGE/DISCHRGE indicator,

OPERATIONS counter and provision for manual charging the breaker.

Primary Disconnect

The primary disconnect finger set is rugged and easy to inspect. Designed

for optimum contact, built of silver-plated copper and tested for

continuous and short time current. Cycloid design is more convenient to

connect and expand wider contact area than flat design. These

disconnects provide proper contact integrity throughout the life of the

gear for the critical primary disconnect function.

Breaker Mechanism

All the mechanical parts of the mechanism are integrated into opening

and closing modules individually. The closing and opening modules areuniversal to whole series of SecoVac embedded pole vacuum circuit

breaker in spite of the ratings. Such design assures no mechanical

readjustment after the replacement, thereby not only shortens lead-time

but also reduces operation and maintenance cost.

Interlock System

For personnel safety, SecoVac is designed with a number of mechanical

and electrical interlocks. For example, breaker contacts must be open

before the breaker can be moved to or from the CONNECT position. A

positive mechanical stop is provided when the breaker reaches theCONNECT or TEST/DISCONNECT positions. Mechanical interference

interlocks are provided to permit only the insertion of properly rated

breakers into any specific compartment. These and other necessary

interlocks provide a comprehensive protection system. Furthermore,

springs automatically discharge when the breaker is withdrawn from the

CONNECT position and breakers cannot be inserted in the closed position.
