Power Distribution Equipment Substation Neutral Point Grounding Resistor

Product Description and Application

Suitable for single phase grounding fault during operation of generator,when arc occurs to the fault point, the winding insulation damage scope will be further increased causing short circuit between phase or turns.For this reason,high resistance grounding is usually used for neutral point of generator so as to restrict grounding current and prevent damage of overvoltage.At present,this device is widely used for urban power supply system,power plant,metro,metallurgy and petrochemical industry.

Product Features

1. The product adopts high quality of imports of stainless steel, or the Domestically produced stainless steel,or zinc oxide ,with the good characteristic of high electrical conductivity, high temperature coefficient ,withstand corrosion and high temperature, high antioxidant capatity and strength, and stable resistance,the product operates safely and reliably.

2. The product can be usd in varies of medium voltage distribution system.When the transformer adopts the triangle connection, the product can be install independent grounding transformer which is connected with neutal point resistor.

3. The resistance of resistor cubicle can be designed from 1A to 2000A.

4. Resistor cubicle applies to indoors or outdoors.Cubicle adopts stainless steel or cold rolled plate , plastic spraying to made, and it can be prevent from corrosion and have high protection grade.

5. The product can increase the count function. Can record the resistance grounding times.

6. The production can increase the disconnection switch,it’s convenint for repairing.Also can increase temperature and humuidity of controlling equipment.
