Features:
ZWZ1 circuit breaker adopts three-phase common box and composite insulation structure. The outer insulation adopts epoxy resin cast pole structure, which has reliable insulation performance and strong anti-pollution ability. The internal insulation adopts a composite insulation composed of vacuum and environmental protection gas. There is no transformer oil or sulfur hexafluoride gas in the box, which meets the requirements of oil-free transformation and environmental protection. The circuit breaker mechanism is a three-phase independent permanent magnet mechanism with reliable performance and can be upgraded to a phase selection switch. The isolation knife gate is inside the box, which reduces the corrosion of the isolation switch from the external environment and affects the breaking performance of the upper switch. The isolation switch adopts a separate manual and electric integrated operating mechanism. The circuit breaker has reasonable design, compact overall structure and convenient installation. Especially suitable for urban and rural outdoor power grids, and small outdoor transmission and distribution systems. Installing a controller can realize the automation of distribution network, and installing wireless communication can realize remote control.
