Phase failure protector phase failure threshold setting method and device, medium and computer equipment

Abstract

The invention relates to a phase failure protector phase failure threshold setting method and device, a medium and computer equipment. The method comprises the steps that the voltage value outputted by the old probe in the phase failure test of an exciter is acquired so as to obtain each test voltage value; the voltage value of a new probe at each acquisition moment is acquired according to each test voltage value, the corresponding output voltage value of the old probe under multiple preset magnetic field intensity and the corresponding output voltage value of the new probe under multiple preset magnetic field intensity so as to obtain a simulation voltage value; the simulation voltage waveform is generated by using the simulation voltage value of the new probe at each acquisition moment; and the corresponding phase failure threshold of the phase failure protector equipped with the new probe is obtained according to the simulation voltage waveform. Therefore, the phase failure protector is equipped with the new probe and then the new phase failure threshold can be obtained without performing the phase failure test again so that tedious operation required for repeating the phase failure test can be omitted, the time duration for setting the phase failure threshold again can be greatly shortened and the setting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of electrical protection, in particular to a method, device, medium and computer equipment for setting a phase failure threshold of a phase failure protector. Background technique [0002] The rotor winding of the exciter is generally connected with a rotating diode through a current connection, and the rotating diode can rectify the AC current into a DC. Generally, the exciter corresponds to multiple phases, such as 39 phases, and multiple rotating diodes are used to connect each phase respectively. If the diode of a certain phase fails, the phase will be disconnected, which is called phase failure. [0003] In order to ensure the normal operation of the exciter, it is usually necessary to be equipped with a phase failure protector to detect whether there is a phase failure caused by a rotating diode fault during the operation of the exciter. Among them, the working process of the phase failure protector i...
