Description

technical field [0001] The invention relates to the technical field of resistance cabinets, in particular to a pull-out wall-mounted resistance cabinet. Background technique [0002] The resistance cabinet and the neutral point of the generator are grounded with high resistance to limit the ground current and prevent various overvoltage hazards. The neutral point can be grounded through a resistor to limit the fault current to an appropriate value, improve the sensitivity of the relay protection and act on tripping, and at the same time make only local slight burns at the fault point possible, and limit the transient overvoltage to the normal line voltage. 2.6 times of the neutral point voltage, which limits the re-ignition of the arc, prevents the main equipment from being damaged by the overvoltage of the arc gap, and effectively prevents the ferromagnetic resonance overvoltage, thereby ensuring the safe operation of the generator. It has a good effect on reducing the ove...
