Product Detail

Product introduction:

The 126(145)kV HV Vacuum circuit breaker is a cutting - edge high - voltage electrical device designed to ensure the safe and efficient operation of power systems. Leveraging vacuum as the arc - extinguishing and insulating medium, it boasts exceptional performance in rapidly interrupting fault currents, preventing arc re - ignition, and maintaining stable insulation. Its robust construction and advanced operating mechanisms guarantee reliable switching capabilities, even under extreme conditions. Ideal for substations and critical transmission lines, this breaker combines high - voltage handling capacity with long - term durability, reducing maintenance needs and enhancing overall grid reliability.

Main characteristic:

  • High - Voltage Rating: Designed for 126(145)kV, suitable for major transmission and distribution systems.
  • Vacuum - based Arc Extinction: Ensures rapid arc quenching and prevents re - ignition for reliable operation.
  • Robust Construction: Built to withstand extreme conditions, providing mechanical stability and durability.
  • Efficient Fault Interruption: Quickly cuts off fault currents to protect power grid equipment.
  • Low Maintenance: Long - lasting performance reduces the frequency of servicing requirements.

Main technical parameters:

Electric Vehicle Charging Pile Testing Technologies and Failure Analysis
1. Detection Technology for Electric Vehicle Charging PilesEV charging piles are primarily divided into two categories:DC charging pilesandAC charging piles. Let's start with DC charging piles: they communicate with the EV's battery management system (BMS) and directly charge the power battery through the DC charging interface. AC charging piles, on the other hand, rely on the EV's AC charging interface and use the vehicle-mounted charger to complete the charging process. These two types of char
