summary:

ZW32-12 (FDGM) series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as "circuit breaker") is an outdoor distribution switchgear with rated voltage of 12kV and three-phase AC 50Hz. The circuit breaker is mainly used for breaking and closing the load current, overload current and short circuit current in the power line. It has overload and short circuit protection functions, meets the control and measurement requirements, and can also achieve remote control and monitoring functions. It is widely used in substations, industrial and mining enterprise distribution systems as control and operation, especially suitable for places requiring frequent operation.

The circuit breaker complies with technical standards such as GB1984-2003, DL/T 402-2007 and IEC60056.

Normal use environment:

1. The surrounding air can be polluted by dust, smoke, corrosive gas, steam or salt mist, and the pollution level is Class III; 2. The wind speed shall not exceed 34m/s (equivalent to 700Pa on the cylinder surface);

3. Service conditions: The circuit breaker can be used under normal service conditions different from those specified above. Please consult with us.

Structural features:

◆ Three-phase pillar fully enclosed structure with high sealing performance

◇ The breaking performance is stable and reliable, and there is no danger of combustion and explosion; Maintenance-free, small size, light weight and long service life.

◇ Strong moisture-proof and anti-condensation performance, especially suitable for use in cold or humid areas.

◇ The material has good insulation performance, high temperature resistance, ultraviolet resistance and aging resistance.

◆ Efficient and reliable miniaturized spring operating mechanism

◇ The power of energy storage motor is small, and the energy consumption of opening and closing is low; The mechanism transmission adopts the direct-action transmission mode, with a small number of parts and high reliability.

◇ The operating mechanism is placed in a sealed box to effectively prevent corrosion and improve the reliability of the mechanism.

◆ Convenient and flexible operation and free combination performance

◇ Manual opening or electric opening and closing as well as remote control operation can be adopted.

◇ Realize distribution automation with intelligent controller, or form automatic recloser and sectionalizer with reclosing controller.

◇ Two-phase or three-phase current transformers can be installed for overcurrent or short-circuit protection.

◇ It can provide current acquisition signal for intelligent controller; Current transformer for metering can be installed according to user requirements.

◇ Three-phase linkage isolating switch can be equipped with anti-error interlocking device; The lightning arrester post insulator can be connected for convenient maintenance.
