Description

technical field [0001] The invention belongs to the technical field of partial discharge monitoring of electric power equipment, and in particular relates to a partial discharge detection and alarm device of electric power equipment. Background technique [0002] With the improvement of power transmission and transformation voltage level, the voltage of power equipment is getting higher and higher, and the requirements for insulation performance of power equipment are getting older and higher. In these devices, due to defects in electrodes and insulation surfaces, loss of insulation outside the wires or aging, etc., the local amplification of the power equipment may be caused. If such accidents are not handled in time, it may lead to the final breakdown and aging of the insulation. , and even cause damage to power equipment. Therefore, the partial discharge monitoring technology of power equipment is an important means to discover hidden dangers in time and improve the relia...
