The ZW32-12 high-voltage transformer circuit breaker is an outdoor AC high-voltage vacuum circuit breaker. The following is a detailed introduction to it:
### Structural Features
- **Overall Structure**: It adopts a three-phase pillar structure with a fully enclosed design and the three phases are separated.
- **Insulating Materials**: The three-phase pillars and current transformers use imported outdoor epoxy resin solid insulation or indoor epoxy resin with an outer layer of silicone rubber solid insulation, which has the characteristics of being resistant to high and low temperatures, ultraviolet rays, and aging.
- **Operating Mechanism**: It adopts a miniaturized spring operating mechanism. The energy storage motor has a low power, and the energy consumption for opening and closing is low. The mechanism transmission adopts a direct-acting transmission mode with a small number of parts and high reliability.
### Working Principle When the circuit breaker receives an opening or closing instruction, the operating mechanism drives the moving contact to move in the arc extinguishing chamber to realize the disconnection or connection of the circuit. When interrupting the current, the vacuum environment in the arc extinguishing chamber enables the electric arc to be quickly extinguished, avoiding the damage to the contacts and equipment caused by the electric arc.
### Performance Parameters
- **Rated Voltage**: 12KV. - **Rated Current**: Common specifications include 630A, 1250A, etc. - **Rated Short-Circuit Breaking Current**: Generally 12.5KA, 16KA, 20KA, etc. - **Rated Short-Circuit Making Current**: The peak value can reach 31.5KA, 40KA, 50KA, etc.
- **Mechanical Life**: It can be as high as 10,000 times. ### Application Scenarios
- **Substations**: It is used for line protection and control on the 10kV side of substations and can realize the breaking and making of load current, overload current and short-circuit current.
- **Urban and Rural Power Grids**: In the distribution grids of cities and rural areas, as a line sectionalizing switch, it can improve the power supply reliability and reduce the scope of power outage due to faults.
- **Industrial and Mining Enterprises**: It is suitable for the internal distribution systems of industrial and mining enterprises to protect and control equipment. How much is the price of the ZW32-12 high-voltage transformer circuit breaker? The price of the ZW32-12 high-voltage transformer circuit breaker is roughly between 3,000 yuan and 4,950 yuan. The following are the price situations of different manufacturers, models and configurations:
- **Wankong Electric Equipment Manufacturing Co., Ltd.**: The price of the electric intelligent circuit breaker with the model ZW32-12F/630 is 4,950 yuan per unit.
