General description:

ZW6-12 outdoor AC high-voltage vacuum circuit breaker is a new dry type outdoor vacuum circuit breaker developed try Nature Science and Technology. It is mainly used in 3-phase AC 12 kV, 50Hz urban power distribution network and countryside electric power network as an outgoing line, sectional, interconnection and branch switch to open or close the load current, overload current and short circuit in the power distribution system.

Main features of this product:

  1. The circuit breaker itself consists of conductive circuit, insulation system, sealing and the enclosure .The conductive circuit consists of incoming and outgoing lines conductive pole, moving and static terminal support, conductive clamp and vacuum are extinguish chamber. The external insulation mainly consists of epoxy resin bushing and silicone rubber insulators. The internal insulation is realized by inside epoxy resin insulation parts and air. The vacuum are extinguish chamber external insulation is realized by silicone rubber.
  2. The isolation knife is mounted on the top of the circuit breaker itself and use welding steel bracket to assemble with the circuit breaker itself. The mechanical locking device on the drive shaft is linked with the circuit breaker mechanism to prevent isolation switch and the circuit breaker from faulty operation.
  3. The operation mechanism is manual energy storage or electrical energy storage mechanism and it could open or close manually or electrically. It has over-current protection function. The whole structure consists of closing spring, energy storage system, over current tripper, closing and opening coils, manually opening and closing system, auxiliary switch and energy storage indicator.
  4. The arc extinguish chamber external insulation is silicone rubber insulation.
  5. Inside the enclosure, the insulation parts are isolated from air with anti-condensation design to strengthen the inside insulation level.
  6. Both incoming and outgoing line bushings are epoxy resin bushing with pouring silicone rubber i:sulation. The creep distance is 38.6mm/kV. Also it enhances its contamination prevention capability.

Main purpose:

zw6-12 outdoor AC high-voltage vacuum circuit breaker (circuit breaker for short in the following) is mainly used in three-phase AC 12 KV and 50 HZ power system. It is used to break and close load current, overload current and short-circuit current in the electric power system. It is used to protect and control the power distribution system in transformer substation, industrial and mining establishments, and also suitable for countryside power network and places with frequent operation, and especially suitable for the transformation of the power network of city and countryside.
