Power supply and distribution energy-saving device system capable of changing electric power parameters

Abstract

The invention relates to a power supply and distribution energy-saving device system capable of changing electric power parameters. Unnecessary energy consumption exists in the voltage frequency testing process of a traditional power saver. According to the method, multiple factors such as voltage, frequency, leakage current and grounding resistance are bound with a time sequence, the defect that a traditional method only aims at a certain time point is overcome, the test precision and accuracy are improved to a great extent, the requirement of electric equipment for electric energy quality is met, meanwhile, the higher electricity-saving yield is obtained, and the method is suitable for popularization and application. A threshold time sequence, a timing module and the like are fully utilized, all module links are started in sequence, invalid continuous actions of part of modules are avoided, the core point, namely energy conservation, is further met, and the utilization efficiency of electric energy is improved to the maximum extent; the grounding alarm test, the overvoltage alarm test, the voltage leakage alarm test and the current leakage alarm test can be carried out on the electric equipment more conveniently, when the test is abnormal, the voltage is controlled to be cut off in time, and electric power accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution energy saving and testing, and in particular relates to a power supply and distribution energy saving device system capable of changing power parameters. Background technique [0002] Since the second half of this year, most regions in my country have implemented power restriction and production restriction, because power supply and distribution are restricted. In power consumption, power distribution, power transmission, power generation, and power systems, there are more and more power electronic equipment, specifications and models are becoming more and more complex, and performances are getting better and better; Its impact; user end impact, high-power electrical equipment start-stop impact and its superposition; a large number of other equipment such as frequency converters are used. As a result, parameters such as the test voltage frequency of the traditional power sav...
