The ZW32 integrated circuit breaker with metering box is an outdoor high-voltage intelligent vacuum circuit breaker that integrates electric energy metering functions, suitable for three-phase AC power distribution systems with a rated voltage of 12kV and a frequency of 50Hz. Its main functions are to make and break load currents, overload currents and short-circuit currents in power systems, and it is widely used in power distribution systems of urban power grids, rural power grids, substations, industrial and mining enterprises, especially suitable for places with frequent operations and oil-free transformation.
The core feature of this equipment lies in its integrated design, which combines the circuit breaker body and the inverted metering box into a compact unit. The product usually adopts a three-phase separated column structure, and a single-phase fault will not cause a three-phase short circuit, which improves the system reliability. The vacuum interrupter is cast in an insulating sleeve or sealed with silicone rubber, which effectively eliminates short-circuit faults caused by condensation, and has excellent hydrophobicity and anti-pollution ability, adapting to harsh outdoor environments such as high temperature and humidity. The overall weight of the circuit breaker is light (usually less than 100 kg), it is easy to install, and supports single-pole or double-pole pedestal installation methods.
Main technical parameters include: the rated current is generally 630A, the rated short-circuit breaking current can reach 20kA, and the mechanical life can reach 10,000 times. Its operating mechanism can be a spring operating mechanism or a permanent magnet mechanism, with the characteristics of small size, low energy consumption and high reliability. The equipment supports manual, electric, infrared and remote operations, and can be matched with a controller to realize power distribution automation or form a recloser with a recloser controller. According to user requirements, a disconnector can also be added.
The use environment conditions usually require an altitude of no more than 2000 meters, an ambient temperature range of -45°C to +65°C, a wind speed of no more than 35m/s, and the installation site should be free of flammable, explosive, chemical corrosion and severe vibration.
