Phase splitter wiring state discriminator

Abstract

The invention discloses a phase splitter wiring state discriminator, and particularly relates to a discriminator for detecting whether a phase splitter wiring state is correct before a phase splitter starting test and preventing failure caused by starting a phase splitter in a wrong wiring state. The discriminator mainly solves the problems that failure of a phase splitter, an electrical appliance and the like is probably caused by starting the phase splitter under the condition of wiring error due to asymmetry of a three-phase winding of the phase splitter and loss is caused by burning down equipment under a serious condition. In the invention, working power is provided for an RLC (Radio Link Control) circuit and an electronic circuit from 110 V direct current by a power supply; the phase splitter and the RLC circuit form an oscillating circuit; three signals are generated to form three pulses through a pulse forming circuit; and the three pulses are output to a display circuit to display the wiring state of the phase splitter through a pulse comparison circuit. The discriminator has a small size and is convenient to operate; the wiring of the phase splitter is discriminated by using the discriminator; and the unnecessary loss brought by wiring error is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric locomotive testing, and in particular relates to a splitter wiring state discriminator for identifying the wiring state of a splitter and avoiding faults caused by starting a splitter in a wrong wiring state. Background technique [0002] In the electric locomotive test, the splitter starting test is a very important test item. The splitter is a special motor used on electric locomotives. Its purpose is to "split" single-phase alternating current into three-phase alternating current for use by three-phase alternating current motors. Due to the asymmetry of the three-phase windings of the splitter camera, it is very important to check whether the relevant circuits of the splitter camera are correct for the operation of the splitter camera and whether the power generation is normal. Faults will cause tens of thousands of losses to burn equipment in severe cases. At present, there is no relevant met...

[0002] In the electric locomotive test, the splitter starting test is a very important test item. The splitter is a special motor used on electric locomotives. Its purpose is to "split" single-phase alternating current into three-phase alternating current for use by three-phase alternating current motors. Due to the asymmetry of the three-phase windings of the splitter camera, it is very important to check whether the relevant circuits of the splitter camera are correct for the operation of the splitter camera and whether the power generation is normal. Faults will cause tens of thousands of losses to burn equipment in severe cases. At present, there is no relevant method to check whether the wiring of the splitter camera is correct.
