The motor protector is used to comprehensively protect the motor. When the motor has overloading, lack of phase, blocking, short -circuit, overvoltage, under voltage, leakage, three -phase imbalance, overheating, bearing wear, setting rotor eccentricity, alarmOr protective device.There are two types of compressed motor protectors widely used at home and abroad: dual metal type and thermal resistance+electronic module model.They have different structures and different functions.
Electric protector parameter
The measurement function of the motor protector has three voltage protection. The protection range of the protection range can be set freely. It has the ability to perform two -level protection. The relay output definition is flexible. It can provide two output modes of the level and pulse.All can be displayed in real time through the panel LCD display. System parameters can be set through panel buttons or upper machine communication settings, and all key data (system parameters, etc.) have two -level password management authority (system parameters, etc.) can save more than ten years of complete accident records for more than ten years.And self -inspection function, friendly man -machine interface measurement measurement of three -phase voltage, current, zero -sequential current, power and powerless power, power factor, power and powerless electricity, frequency, etc.The maximum instant current value of the second start is displayed in real time, and the simulation output function has a 4-20mA output port. In real time, you can monitor three -phase and three -stream, line voltage, power, power factor in real time.The function has 9 remote faith inputs, and 5 remote control is opened to achieve remote faith, remote control, protection and on -site control functions.

Electric protector wiring
1. According to the power supply methods of different electrical equipment, select different electric equipment for power supply for single -phase 220V power supply for single -phase leakage protectors. The diode second -line or single second -line leakage protector should be selected.Three -phase and three -line 380V power supply electrical equipment should be used for electrical equipment for power supply.Three -phase four -line 380V power supply electrical equipment or circuit shared by single -phase equipment and three -phase equipment should be selected.2. According to the normal leakage current of the electrical circuit, when selecting the rated leakage electric action current of the leakage protector, the rated leakage leakage electric operating current value of the leakage protector should be fully considered.The rated leakage non -action current of the leakage protector should be less than 2 times the maximum value of the normal leakage current of electrical lines and equipment.The rated voltage, rated current, short -circuit breaking capacity, rated leakage current, and disconnection time of the leakage protector shall meet the requirements of the protection of the electric supply line and electrical equipment.
