ENR-BNR transformer neutral earthing resistance cabinet

Description:     

Our company focus on the R & D, production and sale of the neutral earthing resistance complete set device. Our product high and low voltage neutral earthing resistance cabinet complete device has the stable performance. Our company introduces and absorbs the advanced foreign technology then develops and produces the ENR-BNR series transformer neutral earthing resistance cabinet which used for 6~35kv system. It has the good performance to reduce the over voltage from the grid, to improve the safety and reliability of grid.

 

This product is made of special stainless steel alloy material. The stainless series ENR-BNR transformer neutral earthing resistance cabinet can be used in 6~35kv system. It has large earth capacitor current in the cable power supply system. There possible appears the arc earthing overvoltage.

 

Neutral use the resistance earthing method in order to inject the resistance current for the failure points. The amount of resistance current is 1.05~1.1 times as many as capacitor current.

It can moderate restrictions the fault current to improve Relay Protection sensitivity and limit the temporary overvoltage as 2.6 times of normal phase neutral voltage. To prevent arc over voltage damage the main equipments and also has a distinct role for ferromagnetic resonance over-voltage at the same time.

 

Technical parameters:

 

Please provide special using condition for this product before you place the order

 

 

Features of product

Top of the cabinet enclosure installed the rings for easy lifting.
