Product Description

General

Farady has own R & D team with outstanding technology and sophisticated equipment, advanced technology introduction and digestion of foreign countries, long-term commitment to the production of neutral grounding technology product research and development; to reduce the overvoltage and improve the safety and reliability of the network.

Farady import special stainless steel alloy materials, development and production of a series of neutral grounding resistors of the stainless steel cabinet, for 6 ~ 35kV AC network. In the system of cable power supply, the grounding capacitance current is larger. When the current is greater than the specified value will be generated when the arc grounding overvoltage. Injection of resistive current of the neutral grounding resistors mode is to give the point of failure, the fault current is resistive and capacitive properties, reduce the phase difference and voltage, reduce the fault current zero arc after the resignation rate, the overvoltage is limited within 2.6 times the phase voltage, improve the sensitivity function the relay protection on the trip, in order to effectively protect the normal operation of the system.

In the 6 ~ 35kV alternating current network, especially in the network with the cable power supply, the resistance grounding is widely used. However, if the transformer winding is delta connection, neutral point grounding grid, earthing transformer must be installed, and a resistor is arranged between the earthing transformer neutral point and the ground.

FL-NGR transformer neutral grounding resistor cabinet is a farady with complete sets of equipment including earthing transformer, the development requirements of these systems can be installed in the power plant power system, substation power supply system, industrial and mining enterprises in the distribution system, the realization of these grid uses in point via neutral grounding resistor system.

2, the resistance cabinet can be fixed on the concrete foundation, to maintain the resistance level. The equipment case should be grounded by the foot of the cabinet. The external dimension of the resistance cabinet is determined according to the specific parameters of the user. The following is the outline size of FL-NGR-6/400:
