13.8kv Neutral grounding resistor cabinet and low resistance grounding complete equipments

Description:     

 

Shanghai EK Electric Co., Ltd. provides 13.8kv Neutral grounding resistor cabinet and low resistance grounding complete equipments.

The Features of the Product

ENR-FNR type Neutral grounding resistor cabinet dedicated to the Power plant generators which use the high resistance grounded complete equipments. Main voltage class of generator is 6kv~20kv.

It can limit the earthing current in a very small value and can effectively suppress arcing earth transient overvoltage when one side of the determinants is earthing.

 

The use of environment

 

Grounding transformer parameters Insulation class: H

Temperature: ≤ 100K

Cooling type: AN

Protection class: the protection class of insulation dry type earthing transformer products can divided into IP00(without crust), IP20 and IP23(with crust).

Insulation level, impedance voltage, load loss, load loss all according to relevant national standards.

 

 

ENR-FNR ENR-FNR type Neutral grounding resistor cabinet within the dry type single phase earthing transformer, resistors, dis-connectors, surge arrester and some other electrical equipment. All these can be easily installed near the generator Neutral. There also installed the current transformer measuring device in ENR-FNR ENR-FNR type Neutral grounding resistor cabinet which can measure the current and output the analog variable.

 

Notes for equipments

  1. cabinet at the time of acceptance.
  2. cabinet conductor cross section and type are decided by the customer.

 

Material: cold-rolled steel spray cabinet (or stainless steel) processing, lead the connect wires from wall bushing to the top or cable entry from the bottom of the cabinet.
