Product Description
ZW32-12 outdoor high-voltage AC vacuum circuit breaker for the rated voltage 12kV, three-phase AC 50Hz outdoor high-voltage power distribution device. It is suitable for the use of load current, overload current and short circuit current in power distribution system of substation and industrial and mining enterprises at 1000m altitude. It is also suitable for rural power grid and frequent operation.
ZW32-12 outdoor high voltage AC vacuum circuit breaker in line with national standards GB 1984-2014 "high voltage AC circuit breaker", JB / T3855-2008 "high voltage AC vacuum circuit breaker", DL / T 403-2000 "12kV ~ 40.5kV high pressure vacuum Circuit breaker ordering technical requirements "of the relevant provisions
Features
Using the overall structure of the design, three-phase pillar of an electrical part of the operation with the box into a unified overall, unique and unique.
Circuit breaker with three-phase pillar structure, with breaking performance stable and reliable, no combustion and explosion hazard, maintenance-free, small size, light weight and long service life and so on.
Vacuum interrupter with fully enclosed solid structure, moisture, anti-condensation, especially suitable for high temperature and humidity areas.
Three-phase pillar and current transformer using outdoor epoxy resin casting or silicone rubber casting, with high insulation properties, with high and low temperature resistance, resistance to ultraviolet light, anti-aging and so on.
Operating mechanism can be used miniature spring operating mechanism can also be used permanent magnet operating mechanism, the mechanism of transmission using direct transmission mode, fewer components, sub-closing low energy consumption, high reliability. The operating mechanism is placed in a sealed mechanism box, which solves the problem of corrosion of the mechanism and improves the reliability of the mechanism.
Circuit breaker of the sub-closing operation can be used manually or electric operation and remote control. Can be equipped with the controller to achieve power distribution automation, but also with the recloser controller with the composition of recloser.
The circuit breaker can be equipped with two-phase or three-phase current transformers for over-current automatic trip protection and intelligent controller for information analysis.
The circuit breaker can be equipped with unilateral or double-sided cutters to provide security for maintenance.
