Model and meaning
Features
BGH1-12P adopts mature spring operating mechanism, stable performance, reliability, long life, simple operation, excellent anti-corrosion ability, and requires very little maintenance during the lifespan
The BGH1-12P solid-sealed pole adopts environmentally friendly high-strength insulating materials, and the altitude can reach 2000 meters. The unique contact material and the application of a plum blossom contact make the BGH1-12P solid-sealed vacuum circuit breaker suitable for various medium voltage systems. occasion.
All products have gone through hundreds of mechanical operation running-in tests before leaving the factory, ensuring that the product performance is at the most stable stage
The overall dimensions and the interlocking method of the cabinets are fully compatible with the domestic mainstream medium voltage switchgear KYN28 cabinet, with high versatility, greatly reducing the design cost
Adopt advanced imported testing equipment, truly record the no-load mechanical characteristics of each product, and provide users with these characteristic curves to ensure the reliability of product quality according to the extended electrical life E2 level and extended mechanical life M2 in GB1984-2003 Class and capacitive current switching has a very low probability of heavy breakdown. C2 type test product assembly adopts tooling to ensure dimensional consistency. All products have undergone a standard cabinet push test before leaving the factory to ensure that the products are mutually compatible. Interchangeability and versatility

The best choice of control and protection in medium voltage power supply and distribution system
The operating mechanism of the solid-sealed vacuum circuit breaker is a spring energy storage mechanism with excellent performance. It adopts an integrated design to optimize the distribution of the main components of the mechanism, simpler mechanism and more stable performance. The assembly and maintenance of the mechanism part are very simple, and the energy storage mechanism is composed of a sprocket structure, a transmission device and a closing spring, and the mechanism is compact and small. The operating mechanism is usually equipped with manual energy storage device and electric energy storage device, which can realize automatic reclosing function.
The circuit breaker of the manual energy storage operating mechanism is usually equipped with manual sub-station operation button, circuit breaker position indicator and spring mechanism energy status indicator, switch operation frequency counter shunt trip, auxiliary switch, position and fault signal and other devices.
Circuit breaker of electric energy storage operating mechanism: additional auxiliary switches for energy storage motor, shunt release, anti-trip relay, and energy storage motor release. The following accessories can also be provided according to specific requirements: undervoltage release, overcurrent relay, etc.
