Locomotive voltage regulator comprehensive test stand

Abstract

The invention provides a locomotive voltage regulator comprehensive test stand. An operation panel is provided with an indicating lamp concentration region, a voltage / current display concentration region, a rotation adjusting switch concentration region and an input and output concentration region from the top down in sequence. The surface of the voltage / current display concentration region is provided with a plurality of voltage / current displayers; the voltage / current displayers adopt digital light-emitting displayers; the digital light-emitting displayers are connected with a locomotive voltage regulator comprehensive detection device through wires; the rotation adjusting switch concentration region is provided with a voltage rotation regulator; and the voltage rotation regulator adopts a membrane-type variable resistance regulator. The test stand reduces voltage value reading difficulty, improves value reading accuracy, reduces reading error, prevents reading blind areas, and reduces the possibility of misreading; and the voltage is adjusted through the membrane-type variable resistance regulator, so that workload of technical personnel is reduced effectively and locomotive voltage regulator is higher in adjusting precision.

Description

technical field [0001] The invention relates to a comprehensive test bench, in particular to a comprehensive test bench for a locomotive voltage regulator, and belongs to the technical field of detection devices for a locomotive voltage regulator. Background technique [0002] The locomotive voltage regulator comprehensive test bench is an instrument used to detect whether the voltage regulator is working normally. It is used for diagnosis and technical inspection before the locomotive voltage regulator is installed and during the manufacture and repair of the locomotive voltage regulator. The voltage regulator comprehensive test bench can check the performance and parameters in the circuit, as well as determine the technical status of individual components and functional components, can adjust the voltage of the voltage regulator, improve the stability of the power system, and play an irreplaceable role in the industry .

AI Technical Summary

Problems solved by technology

[0003] In the comprehensive test bench for locomotive voltage regulators in the prior art, each part of the display mainly displays the value through the pointer. It is difficult to read and observe the value, and sometimes there will be some reading errors, and the display is in the dark. It is difficult for technicians to see the value clearly, and it is very difficult to read the voltage value, which makes the technician's observation blind, and there is no suitable voltage value display, which is likely to cause misreading. At present, some voltage regulators are practical and operable. It is not high, which increases the workload of technicians. At the same time, the use of regulators is more complicated, which is not convenient for technicians to operate. Therefore, it is very important to improve the comprehensive test bench of locomotive voltage regulators, and it needs to be further improved.

[0004] On the whole, the locomotive voltage regulator comprehensive test bench of the prior art mainly has the following defects: one is that the pointer display value of the prior art makes it difficult to read and observe the voltage value, and the accuracy of the pointer reading value is not good. High, it will cause some errors in the voltage value; second, the display of the comprehensive test bench of the locomotive voltage regulator does not use a light-emitting display panel, and the existing display is difficult for technicians to see the voltage value in the case of relatively dark light. There is a blind area in reading the value, and the correct value cannot be read, which is likely to cause misreading; third, the accuracy of the current voltage regulator is not high, and when the voltage is adjusted to 110V, there will be an error of ±5V, which is not suitable for maintenance technology demand, the practicability is not strong, and the voltage regulator is more complicated, which increases the workload of technicians
