Structural diagram of the new ZW7 electric operated high-voltage vacuum circuit breaker in Chengdu

The new ZW7-40.5 vacuum circuit breaker is smaller in size than the old ZW7, reduces space for easy installation, is lightweight and easy to transport, has a simple structure, fewer moving parts, and is completely suitable for pole mounted single bar connection.

ZW32 structural characteristics
1. The circuit breaker adopts a three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no combustion and explosion hazards, maintenance free, small size, light weight, and long service life.
2. The circuit breaker adopts a fully enclosed structure with good sealing performance, which helps to improve moisture-proof and anti condensation performance, especially suitable for use in cold or humid areas.
3. The three-phase pillars and current transformers adopt imported outdoor epoxy resin solid insulation, or indoor epoxy resin wrapped with organic silicon rubber solid insulation; It has the characteristics of high and low temperature resistance, UV resistance, and aging resistance.
4. Circuit breakers can be equipped with two-phase or three-phase current transformers for overcurrent or short-circuit protection, and can also provide current acquisition signals to intelligent controllers; According to user requirements, measuring current transformers can be installed.
5. The circuit breaker can be equipped with a three-phase interlocking isolation switch, which has a visible fracture when the isolation switch is in the open state, and has an anti misoperation interlock device with the circuit breaker body. The circuit breaker can only be operated when the isolation switch is fully closed or fully opened. Can be connected to lightning arrester post insulators for easy maintenance.
