Abstract

The invention relates to a test system and a test method for a passenger train DC110V online insulation monitoring system. A circuit breaker, a change-over switch, a potentiometer, a voltmeter, a voltage sensor, a PLC, a touch screen, a leakage alarm and other electrical elements are connected to constitute a test system for the insulation monitoring system in a broadcasting carriage, ordinary carriages and a first / last carriage of a train under test. By switching the change-over switch and the circuit breaker, relevant tests can be carried out on the ordinary carriages, the first / last carriage and the broadcasting carriage without train formation.

Description

technical field [0001] The invention relates to a technology for monitoring leakage and voltage of electrical equipment or components, in particular to a test system and test method for a DC110V on-line insulation monitoring system for railway passenger cars. Background technique [0002] At present, the main types of railway passenger cars in my country are DC600V powered passenger cars. DC600V power supply bus power trunk line is divided into DC600V power supply trunk line and DC110V power supply trunk line. The DC600V power supply main line is equipped with a main line insulation monitoring system. The monitoring system can monitor the leakage current of the 600V power supply main line and the voltage of the main line to ground in real time, and has functions such as early warning, alarm, fault record, and network communication. The original design of the DC110V power supply trunk line did not have an insulation monitoring system. However, in recent years, electrical fir...
