Product Description

TBP Three phase composite over-voltage protector is a new and original over-voltage protective device. It is used in AC power system for under 35KV to protect the electric equipment insulation for transformer, motor, paralleled compensation capacitor, etc. This product can limit to atmosphere over voltage and operation over voltage caused by vacuum breakers, in addition, it can play secure limitation to over voltage of the phase to phase and the phase to earth.
TBP three phase composite type over-voltage protector connects with four stars type by four arresters composing diagram, so that every phase to ground and phase to phase over voltage can be protected. because of the clever mating, one set arrester takes phase to earth protective affect. Meantime, overcoming fault that simple three arresters star shape connecting can not protect the phase to phase over- voltage better.
Three-phase composite type over-voltage protector is designed in the term of faults of current over voltage protector. This protector includes four groups ZnO valve elements, it has the super excellent features that other similar products can not compete with it.
The housing of this product is made of flame-resistance and anti-aged silicon rubber, because four HV cables made of silicon rubber can be leaded out, and the whole of ZnO valve element is proceeded integrated sulphation and primary die stamping, the protector can show many advantage such as good electric insulation, high dielectric strength, anti-electric corrosion, anti-aged, small volume, convenient insulation, the distance among phases and creepage distance can not be considered, the protector can be installed flexibly in the term of location.

Use Notes

The over-voltage protector should be tested before use after operation each year as following testing items:
1. Test of DC U1mA voltage
CD voltage is applied to A-D,B-D,C-D,A-C,B-C and A-B terminals respectively. After the current stabilized to 1mA,record the voltage value. If the voltage value is large than specified value,the protector qualified. Recommend that test one time each year.
2. Dc leakage current
DC 75% U1mA voltage is applied to A-D,B-D,C-D,A-B,A-C and B-C terminals respectively. After voltage becomes stabilization, record the current value. If the current value is not large than 50μA,the protector is qualified. This test should be done before use. Recommend that test one time each year.
3. When doing the voltage-withstand test,the electric equipment protected by the over- voltage protector should be disconnected.
4. When dismounting the over- voltage protector,can not carry the leads of the over-voltage protector by hand.
