The resistor cabinet is a good set of grounding equipment, including ground transformers, and also has a wide range of applications.The Al-BNR resistor cabinet can be installed in power plant power system, power transmission system, mineral enterprise power distribution system.
The resistor is divided into indoor and outdoor.The inline mode can be used as a downward and down, and the top of the cabinet is contained in the top of the cabinet.The top of the cabinet is equipped with a lifting ring for a lifting. In the 6-66 kV AC grid, the ground capacitance current is large in the 6-66 kV AC grid.An arc-ground overvoltage is generated when the current is greater than the specified value.The purpose of using neutral dotting electrical blocking is to inject the resistive current to the fault point, so that the ground fault current is contracted, reducing the phase difference of the voltage, reducing the heavy ignites after the fault point current is over zero exterior, so thatThe overvoltage is limited to 2.6 times the phase voltage, and the sensitivity of relay protection is improved to trip, thereby effectively protecting the system normally
