W39 high-voltage vacuum breaker is used in AC 40.5kV﹑50Hz three-phase electric system as protection and controll of mining industry enterprise, power station and transformer station. The product can be operated frequently and be a role of contact breaker.
Product feature
Breaker can append internal-external transformer .
Breaker can be mounted with four currency transformer at each phase. Appending currency
transformer iron-core used in microlite alloy and super-conduct magnetic material . Their precision of currency on transformer can be reach 200A or above equal to class of 0.2 or 0.2S . The whole structure of breaker is so compact that it can fully optimize packing tech for second winding . It fully guarantee regular shape, smooth margin, unmovable on drying, non-distortaion after it is fixed into mainframe and keep field average.
There is micro-positive pressure SF6 gas filled between vacuum arch-quenching chamber and porcelain flat, ensure free of condensation and wet-absord. Get rid of air bubble, impenetration discharge, difficulty from maintenanec and repair affected by inner filling organic insulated material.
Dominant secondary component all select high-grade product, high reliablity of operation.
Product revealing parts’ surface apply for galvanization and high–grade stainless plate. Anti-erosion is predoment.,
It can directly replace SW2—35type oil-minimum breaker.After add transition bracket, it can replace many kinds of oil-maximum breaker and be a ideal oilless circuit breaker .
1 select vacuum interrupter contact material, keep low cut-off value below 4A, efficiently suppression over-voltage on the process of operation
2 ability of switching is strong, off-on short circuit31.5kA reach thirty times
3 apply reliable CT10A advanced type that undertake frequent operation and life up to 10000 times.
4 the product can be accomodate itself to environment at altitude 3000m, level of external isolation is high.
