According to the utility model, the voltage can be intermittently measured, the service life of the voltmeter is prolonged, the bending of the lead can be reduced, and the lead can be protected.
Description
technical field [0001] The invention relates to the technical field of power quality control, in particular to a power quality controller capable of intermittently connecting to a circuit to measure voltage. Background technique [0002] The power quality controller is aimed at the working conditions of industrial large-capacity non-linear loads such as rectifiers, frequency converters, large UPS, intermediate frequency furnaces, and electric arc furnaces. [0003] When the existing power quality controller is working, the voltmeter is continuously connected to the circuit, which causes the voltmeter to work uninterruptedly for a long time, which easily reduces the service life of the voltmeter and causes the voltmeter to be easily damaged. [0004] Therefore, it is necessary to design a power quality controller that can intermittently connect to the circuit to measure the voltage for the above problems. SUMMARY OF THE INVENTION [0005] The purpose of the present inventi...
