Abstract

The invention discloses a monitoring system and method of the state of a high-voltage compartment on the roof of a D-series high-speed train. The monitoring systems comprises a supervising system anda monitoring unit; the monitoring unit comprises one or more of the following monitoring units of an environmental information monitoring unit, a busbar temperature monitoring unit, a leakage currentmonitoring unit and an image / video monitoring unit; and the supervising system obtains monitoring data of the monitoring unit to conduct high-voltage compartment fault diagnosis. The monitoring methodof a fault of the high-voltage compartment on the roof of the D-series high-speed train comprises the steps: according to the monitoring data of the monitoring system, environmental fault determination, busbar fault determination, equipment insulation fault determination and equipment abnormity qualitative determination are conducted. An advanced sensing technology, communication technology and control technology are adopted, internal environmental information, high-voltage equipment state information and image / video information in the high-voltage compartment are monitored in real time, a fault early-warning strategy is combined to provide safe early-warning in time, and great significance for ensuring safe operation of a high-voltage system of the D-series high-speed train is achieved.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a state monitoring system and a monitoring method for a high-voltage box on the roof of an EMU. Background technique [0002] The high-voltage equipment on the roof of the EMU is directly exposed to the air, and is affected by environmental factors such as external pollution, ice and snow, sand and dust, high and low temperature, etc., which may easily lead to surface discharge or body breakdown failure of the insulation part of the equipment. In recent years, in order to solve this problem, the high-voltage box on the roof has been developed and applied rapidly, that is, high-voltage equipment such as high-voltage circuit breakers, high-voltage isolating switches, voltage transformers, current transformers, and cable terminals are centrally installed inside the metal box. [0003] The high-voltage box of the EMU is installed on the roof of the car with the pantograph. Taking ...
