Secondary Plug310 11 <strong>12</strong> 13 14 15Unique and Proven Embedded Pole TechnologySecoVac series MV embedded pole vacuum circuit breaker uses the latest and mature technology of Automatic Pressure Gelation (APG) to embed the vacuuminterrupter and connection terminals within epoxy resin. The vacuum interrupter is cast in the epoxy resin, so inside the epoxy resin there is no screw fixationthat will cause the concentrated harsh electrical field inside the epoxy resin and will consequently result in decrease of the electrical insulation strength of thepole. 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 iseasily to be controlled by the state of the art production process. The embedded pole technology also obviously improve the environmental resistantcapability of the breaker, as the primary circuit of the breaker is completely embedded inside the epoxy resin, the risk of insulation fault caused by adverseoperating 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 betweenepoxy resin and ceramic housing of vacuum interrupter, the material and processingof the buffering layer is essential to ensure the integrity of epoxy resin of theembedded pole provide adequate adhesion between each other in any circumstance.Our patented LSR (Liquid Silicon Rubber) buffering layer and double APG (AutoPressure Gelation) process adopted in the producing of the embedded polethoroughly eliminates the cracking of the epoxy resin caused by the large differenceof thermal expansion coefficient between epoxy resin and ceramic in case of rapidchanging of the ambient temperature. APG process for LSR buffering layer ensuresthat there will not be any air gap or bubble between the buffering layer and ceramichousing, hence, the high electrical insulation strength of the embedded pole ofSecoVac series MV embedded pole vacuum circuit breaker is guaranteed.The partial discharge value of embedded pole manufactured by our patented LSR(Liquid Silicon Rubber) buffering layer and double APG (Auto Pressure Gelation)process is below 5pc with an applied testing voltage of 1.2Um.SecoVac 02
SecoVac <strong>12</strong>-<strong>24kV</strong>The State of the art Processing and Advanced Quality ControlThe high quality of the embedded pole is achieved by using the latest APG (Auto Pressure Gelation) technology and advanced vacuum mixing and degassingtechnology that are carried out by the equipment. The Vogel clamping machine is an essential piece of equipment to ensure the mechanical and insulatingstrength 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 SecoVacVCB, 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:• X-ray inspection• Power frequency withstand voltage test• Partial discharge measurement• Extremely high and low temperature impulse testBefore delivery, the following tests and inspections will be done forSecoVac series MV embedded pole vacuum circuit breaker in factory bymeans of advanced testing equipments:• Dynamic characteristics measurement• Power frequency withstand voltage testing• Inspection of interlocking system between breaker and withdrawable unit• Secondary wiring inspection• <strong>Circuit</strong> resistance measurementFull Range Product with High Technical ParametersRated voltage up to <strong>24kV</strong>Rated current up to 4000ARated short circuit breaking current up to 50kAMechanical endurance up to 30,000 operating cyclesRated short circuit breaking times up to 50 timesDC component of short circuit breaking current up to 62%Large external creep distance reaches 20mm/kVSecoVac 04
SecoVac <strong>12</strong>-<strong>24kV</strong><strong>Breaker</strong> FeaturesFront PanelThis front panel fits into a collar-frame in the equipment when the breakeris in the CONNECT position. It provides a metal barrier between thebreaker compartment and the secondary device compartment. Wellmarked and easy-to-read operating controls and indicators include TRIPbutton, CLOSE button, OPEN/CLOSE indicator, CHARGE/DISCHRGE indicator,OPERATIONS counter and provision for manual charging the breaker.Primary DisconnectThe primary disconnect finger set is rugged and easy to inspect. Designedfor optimum contact, built of silver-plated copper and tested forcontinuous and short time current. Cycloid design is more convenient toconnect and expand wider contact area than flat design. Thesedisconnects provide proper contact integrity throughout the life of thegear for the critical primary disconnect function.<strong>Breaker</strong> MechanismAll the mechanical parts of the mechanism are integrated into openingand closing modules individually. The closing and opening modules areuniversal to whole series of SecoVac embedded pole vacuum circuitbreaker in spite of the ratings. Such design assures no mechanicalreadjustment after the replacement, thereby not only shortens lead-timebut also reduces operation and maintenance cost.Interlock SystemFor personnel safety, SecoVac is designed with a number of mechanicaland electrical interlocks. For example, breaker contacts must be openbefore the breaker can be moved to or from the CONNECT position. Apositive mechanical stop is provided when the breaker reaches theCONNECT or TEST/DISCONNECT positions. Mechanical interferenceinterlocks are provided to permit only the insertion of properly ratedbreakers into any specific compartment. These and other necessaryinterlocks provide a comprehensive protection system. Furthermore,springs automatically discharge when the breaker is withdrawn from theCONNECT position and breakers cannot be inserted in the closed position.SecoVac 05
