The main components of medium-voltage switchgear generally include:
Busbar: Busbar, responsible for connecting the power supply and various electrical equipment, and plays the role of current collection and distribution.
Circuit breaker: When the circuit is overloaded or short-circuited, it can automatically cut off the circuit to protect the equipment and system.
Isolating switch: Used to isolate the power supply during equipment maintenance and overhaul to ensure safe operation.
Grounding switch: Used to ground the equipment or system to prevent the risk of electric shock caused by poor insulation.
Current transformer: Detects the current in the circuit for protection and monitoring.
Voltage transformer: Detects the voltage in the circuit for protection and monitoring.
Lightning arrester: Used to protect the insulation of the equipment and prevent atmospheric overvoltage from damaging the equipment.
Load switch: A switch used to connect or disconnect the load current.
Contactor: Used to control the on and off of large currents, often used to start and control motors.
Control and protection unit: Used to monitor and protect the circuit to ensure safe operation of the system.
Note: The specific functions and configurations of the above components may vary depending on the type and purpose of the medium voltage switchgear, so in actual operation they need to be selected and configured according to the specific situation.
