Product Detail

Description ：

The 52kV - 363kV Live tank Vacuum circuit breakers are advanced high - voltage electrical devices. Using vacuum as the arc - extinguishing and insulating medium, they leverage vacuum's superior insulation and rapid arc - quenching capabilities to instantly interrupt fault currents, preventing arc re - ignition and ensuring grid stability. The live tank design encapsulates the vacuum interrupters within a metal tank filled with insulating gas, enhancing insulation, mechanical robustness, and environmental adaptability to withstand harsh weather and external impacts. Available in multiple voltage ratings, these breakers suit diverse high - voltage transmission and distribution scenarios, from urban power grids to industrial systems. Equipped with precise operating mechanisms, they offer long mechanical life, swift and accurate operations, minimal maintenance, excellent short - circuit current interruption, and anti - aging performance, making them an ideal choice for reliable and safe high - voltage power transmission.

Main function introduction:

Wide Voltage Range: Covers 52kV - 363kV, suitable for various high - voltage power systems.
Vacuum Arc Extinction: Utilizes vacuum for rapid arc quenching and reliable insulation.
Live Tank Design: Encased in gas - filled metal tanks for enhanced mechanical strength and environmental resistance.

Capacitor Start Induction Motor

Capacitor Start Induction Motor

Capacitor Start Motors are a type of single - phase induction motors. They utilize a capacitor within the auxiliary winding circuit to create a significant phase difference between the current flowing through the main winding and that in the auxiliary winding. As the name "capacitor start" clearly implies, these motors rely on a capacitor specifically for the starting process. The diagram below illustrates the connection schematic of a Capacitor Start Motor.The capacitor start motor features a c

Analysis of the Fault Causes and Handling Steps of SF6 Circuit Breakers

Analysis of the Fault Causes and Handling Steps of SF6 Circuit Breakers

In an SF₆ circuit breaker, the SF₆ gas can decompose into toxic and corrosive gases and water in a high-temperature environment, which can damage the insulating layer. To prevent this situation, while effectively strengthening the protection of electrical components, the insulation level should also be improved. In addition, faults should be analyzed, and corresponding measures should be taken for treatment.1 Case AnalysisA 110 kV switch in a substation was struck by lightning, causing a reclosi
