Motor train unit electrical operation safety control device and motor train unit electrical operation safety control method

Abstract

The invention relates to the field of electrical safety operation, in particular to a motor train unit electrical operation safety control device and a motor train unit electrical operation safety control method. A safety lock and a hanging lock are combined to lock the disconnection state of a control power supply circuit breaker of electrical equipment of a motor train unit. A circuit breaker locking state measurement and control alarm circuit composed of a surface sensing electrode, a pressing switch and an integrated circuit is arranged in the hanging lock, when a human body touches the surface sensing electrode on the surface of the hanging lock body, alarm prompt can be achieved, and meanwhile, the implementation of the electric operation safety operation method for the motor train unit is more perfect in cooperation with application of an operation signboard. According to the device and the method, the occurrence rate of electric shock accidents can be reduced, so that direct economic loss and compensation economic loss of the accidents are reduced; the number or frequency of casualties is reduced, so that direct loss caused by production halt during working time is reduced; and by creating good working safety conditions, the productivity is improved, so that the output value and profit of a company are increased.

Description

technical field [0001] The invention relates to the field of electrical safety operation of EMUs and locomotives, in particular to a safety control device for electrical operation of EMUs and a method for controlling electrical safety of EMUs. Background technique [0002] The safety system and safety measures for EMU maintenance operations refer to the General Principles of Safety Technical Operating Regulations for Electrical Operations. Normative references include GB / T13869 "Guidelines for the Safety of Electricity Use", GB12158 "General Guidelines for Preventing Electrostatic Accidents", GB / T17045 "General Parts of Electric Shock Protection Devices and Equipment", and GB26859 "Electricity Safety Work Regulations Power Lines" 17 national standards, including 17 national standards, are used in the "China CRRC Safety Technical Operation Regulations" for the electrical operation, maintenance and fault handling of EMUs. The "China CRRC Safety Technology Operation Regulation...

AI Technical Summary

Problems solved by technology

[0009] Although the above-mentioned working procedures meet the relevant safety regulations, with the increasing number of EMUs operated by EMUs, the maintenance tasks have become more and more arduous. In the case of obviously insufficient staffing, maintenance operations and fault handling operations are intertwined and closely connected, and there are serious problems. There are safety risk loopholes, and at the same time, the system of "lowering the bow-sealing the land-disconnecting the isolation switch-electricity test-listing" system is abandoned during the operation, which creates potential safety hazards for the company's electrical workers to be electrocuted; Under the influence of factors such as unprofessional, personality, work attitude, physical condition and psychological quality of individual personnel, it is easy to make some non-standard, habitual, indulgent or arbitrary operations, resulting in service station operators for example When the operation application is submitted and approved in accordance with the regulations, when the high voltage is cut off to carry out the operation, the high-voltage power supply is implemented without notifying the service station dispatcher or the operator to stop the operation and evacuate the operation site. The sudden power supply of the EMU is harmful to the operator Causing electric shock

After combing and analyzing the on-site operation process, the cooperating personnel of the EMU operation station did not notify us to stop the operation in time when the EMU was powered, which resulted in the on-site dispatch failing to grasp the power supply and outage information for fault handling, and the cooperating personnel of the EMU station did not notify the on-site operators of the EMU Group high-voltage power supply information, causing a greater safety risk of high-voltage electric shock to fault handling personnel

Therefore, the existing operating procedures can no longer meet the requirements of the electrical operations, maintenance and fault handling operations of the existing EMUs
