Motor phase sequence protector TG30s for three-phase no-phase protection relay for motor
Product Description
This phase sequence protector is applicable to all phase sequence protectors of three-phase power supply. Versatility (3 ph 220 v ~ 440 v, TVR - 2000 - c (380 v ~ 660 v), is applicable to 50 hz / 60 hz), phase sequence protector super-small size, appearance is very beautiful, are electrical appliances, motor is normal, stable work good partner, phase sequence protector for all kinds of three-phase motor and other three-phase equipment (e.g., refrigeration compressor, water pump, blower, air compressor, elevators, injection molding machine), the input power of three-phase voltage phase, the phase inversion and unbalanced three-phase voltage relay protection.
Dimensions
Specification
I. Protection features of phase sequence protector
Dynamic phase failure and static phase failure protection: any phase failure occurs when the protected device is in running or non-running state. Indicator light: red light, and priority
Phase sequence protection: A protective measure against phase sequence errors of L1, L2 and L3 three-phase AC power supply. Immediate action. Indicator light: yellow light;
Voltage unbalance protection: Protection of a voltage unbalance rate where three-phase voltage unbalance will affect the safe operation of the equipment. When the voltage imbalance rate is higher than 8%. The indicator light form is: the red light is on when the phase is out, and priority is given to it
Delay protection: in case of failure, the monitor will operate after a delay of 1~2 seconds and the relay will release
Lightning protection, anti-surge function: built-in lightning protection, anti-surge protection circuit, maximum protection of your electrical equipment;
Ii. Performance characteristics of phase sequence protector
1. The protection function of the phase loss protector is not affected by the current size of the line or load, impulse current, unbalanced current and the nature of the load. Be able to work in full performance and climate for a long time. Power consumption is no more than 2W;
2. There is no requirement for motor connection mode when it is used for motor protection;
3. The phase loss protector conforms to GB/T 140481-2000, GB140485-2001 EQV IEC60947-1:999;
4. The EMC of phase loss protector conforms to the measurement method and allowable value of radio interference characteristics of GB4343-1995;
Iii. Working characteristics of phase sequence protector
1. The three-phase wiring of L1, L2 and L3 is correct, the monitor green light is on, and the relay pulls in; If the phase sequence is connected incorrectly, the monitor will turn on yellow and exchange any two phases in the three phases Of L1, L2 and L3. The monitor will identify the phase sequence and work normally. When the yellow light appears after the normal operation of the protected equipment and the relay does not pull in, it shall be regarded as the phase sequence misconnection of the external circuit. The monitor has the function of anti-misconnection protection.
2. When L1, L2 and L3 phases are short, the red light is on and the green light is not, and the relay is released; When the voltage is normal, the green light is on and the relay pulls in; 3. L1, L2 and L3 are connected with three-phase AC voltage, and NO and COM are normally open contacts; NC and COM are normally closed contacts. Use a direct wire connection
4. When the three-phase voltage of L1, L2 and L3 is unbalanced by >8%, the red light will be on and the relay will be released; The voltage returns to <5%, the green light is on, and the relay pulls in
Installation Instructions
1. The protector can be directly inserted into 35mmTH type standard installation track, and can be fixed with M2--M4 screw in other occasions.
2.L1,L2 and L3 are connected with three-phase AC voltage, built-in relay output, NO and COM are normally open contacts; NC,COM are normally closed contacts. Use a single hard wire or lug, insert it into the connecting terminal and screw it firmly.
