The relay is mainly used for the protection and control of low-voltage electrical equipment. Different types of relays have different functions. Below we will briefly describe the main functions and functions of several commonly used relays!
Time relay: used in the secondary circuit relay protection and automatic control loop of the power system. As a delay device, the controlled component gets the required delay.
Intermediate relay: Used in various protection and automatic control lines to increase the number of contacts and contact capacity of the protection and control loop.
Overcurrent relay: used in relay protection devices for generators, transformers, and transmission and distribution systems. When the equipment is overloaded or short-circuited, it can act reliably according to the predetermined time limit, signal or cut off the faulty part.
Current Relay: Used in overload and short circuit protection devices for generators, transformers and power lines.
Voltage relay: Used in relay protection devices for generators, transformers and transmission lines as a starting element for overvoltage protection or low voltage blocking.
Leakage relay; used for AC voltage to 660V, frequency 50Hz, current to 1500A and below leakage relay neutral point grounding circuit.
