AHD-12GD(R) Three-Station Vacuum Circuit Breaker

AHD-12GD(R) series indoor high-voltage three-station vacuum circuit breaker has excellent electrical and mechanical properties, reliable and stable mechanism, and long life. The main circuit adopts solid-sealed poles, which improves the environmental adaptability and insulation reliability of the circuit breaker; reliable mechanical and electronic performance, extended mechanical life and electronic life make the circuit breaker maintenance-free possible. It can be used in 3.6-12KV power systems. As a protection box control unit designed for power grid equipment and industrial and mining enterprises, it is suitable for various loads of different natures, frequent operations, and situations where short-circuit currents are broken multiple times. The product has complete mechanical and electrical interlocking devices, with extremely high operational stability and reliability, ensuring the safety of operators and equipment, and ensuring the safety of electricity.
◆Using solid-sealed pole technology
◆The product adopts modular design: frame structure, integrating isolating switch, sealed vacuum circuit breaker, grounding switch, sensor, interlocking mechanism and operating mechanism into a high-performance miniaturized high-voltage electrical product
◆The adaptable cabinet size is (500x1000x1800)mm
◆Rotary isolating switch with visible fracture after opening
◆There are forced mechanical interlocks between the isolating switch, circuit breaker and grounding switch to prevent misoperation
◆The circuit breaker adopts a modular operating mechanism, which can be replaced or repaired independently and has good interchangeability. It can be operated manually, or AC and DC energy storage operations can be used to achieve remote control.
◆The cabinet door and grounding switch are designed with a reliable interlocking structure to ensure the safety of operators
