Abstract

The invention discloses an overhead contact line power supply high voltage system control method and an application thereof. A high voltage system comprises a pantograph type current collector, a maincircuit breaker and a high voltage transformer which are connected with each other in sequence; the pantograph type current collector is in contact with an overhead contact line; and the high voltagetransformer is connected with a rectifier. A high voltage chamber door is arranged between the high voltage transformer and the rectifier; the high voltage system comprises an interlock switch used for reflecting an opening and closing state of the high voltage chamber door. When detecting all signals that the main circuit breaker is in a breaking position, the high voltage chamber door is in a closing state, the oil temperature of the high voltage transformer is normal and the pantograph rising pressure of the pantograph type current collector is enough and not detecting an insulation faultof the high voltage system, the pantograph type current collector can only perform pantograph rising operation. According to the overhead contact line power supply high voltage system control method and the application thereof, the technical problem of safety control of the pantograph type current collector and the main circuit breaker can be solved; and therefore, safe and reliable operation of the overhead contact line power supply high voltage system control method can be guaranteed.

Description

technical field [0001] The invention relates to the field of railway electrics, in particular to a method for controlling a catenary power supply high-voltage system applied to railway engineering vehicles and its application. Background technique [0002] At present, with the continuous increase of the total mileage of my country's railways, the workload of railway maintenance is also increasing. Large-scale road maintenance machinery has become the main force of my country's railway maintenance and repair. Dozens of mechanized construction teams are active on the Wanli railway line every day. These construction teams work in the field all year round, fighting severe cold and scorching heat, and have made great contributions to the development of my country's railway industry, especially to the speed-up of railways in recent years. In order to solve the life problems of the railway maintenance fleet in the field, the railway bureaus have equipped the fleet with camping trai...
