A high-voltage test site safety management and control auxiliary system and control method

Abstract

The invention discloses a high voltage test on-site safety management control auxiliary system and management control method. The system is composed of a main control box with a system state display, four boundary violation signal generation devices which are dispersed at four monitoring points in a high voltage test process, and four hand-held terminals, wherein the main control box and the hand-held terminals are internally provided with wireless transmit-receive modules capable of mutually sending or receiving information respectively; and the boundary violation signal generation devices mainly comprise power source power supply circuits, wireless communication circuits and acousto-optic alarm circuits. During the high voltage test process, monitoring personnel distributed at important monitoring points each manage one terminal and send state signals to the main control box through specific buttons on the terminals; the main control box, according to the received signals, performs corresponding operation automatically or through test operation personnel in a hand-operated manner and send feedback signals to the terminals; the hand-held terminals are provided with duty-specifying, positioning and boundary violation alarm functions, and can realize real-time management of the behaviors of the monitoring personnel through monitoring the distance between the hand-held terminals and other hand-held terminals; and the main control box manages personnel operation authority by adopting a fingerprint identification function so that personnel are on duty and responsibilities are shouldered in the test process, and wrong operation of personnel with unqualified technology level can be avoided.

Description

technical field [0001] The invention relates to a safety control auxiliary system and a control method for a high-voltage test site, and belongs to the technical field of high-voltage test site safety control. Background technique [0002] During the high-voltage test of the power system, especially the withstand voltage test (cable withstand voltage, GIS withstand voltage, switchgear busbar withstand voltage), the applied voltage is relatively high, the voltage action time is long, and there are many unpredictable factors. On-site management and control by means of personal monitoring and timely singing. However, the test involves a lot of equipment, and the guardians are scattered in multiple areas. The sound signals sent by the guardians are affected by site conditions (such as site noise, wall sound insulation, etc.) and cannot be transmitted smoothly; if walkie-talkies are used, channel channeling often occurs , the information may not be communicated to the person in ...

Problems solved by technology

However, the test involves a lot of equipment, and the guardians are scattered in multiple areas. The sound signals sent by the guardians are affected by site conditions (such as site noise, wall sound insulation, etc.) and cannot be transmitted smoothly; if walkie-talkies are used, channel channeling often occurs , the information may not be communicated to the person in charge of the test and the test operator in time, resulting in greater safety hazards; once an emergency occurs, under the action of high voltage, if measures are not taken in time, the personnel and equipment will be damaged. cause serious harm
