Description

technical field [0001] The patent of the present invention relates to a novel power voltage stabilizing device. Background technique [0002] The existing equipment to avoid loop voltage feedback is to set a switch on the secondary side of the voltage transformer. During the inspection and maintenance of the equipment, the construction personnel need to operate in strict accordance with the specifications, but the environmental conditions during construction are different, and the work The intensity is high, the personnel are prone to fatigue, lack of concentration, and the induction secondary circuit voltage feedback phenomenon often occurs, threatening the safe and stable operation of the power system. Existing equipment cannot eliminate these technical problems. Contents of the invention [0003] The concrete technical scheme of this patent is as follows: [0004] A new type of power voltage stabilizing device, which is composed of relays and switches, is characterized...
