Background technique

The switching operation of the power system is to convert the electrical equipment from one state to another or change the operating mode of the system by operating the isolation switch, the circuit breaker, and the connection and disconnection of the ground wire. In many cases, the switching operation is carried out around the maintenance of electrical equipment. In order to ensure the quality of electrical equipment maintenance, the current maintenance is carried out during the day, so that the switching operation is often carried out in the early morning and at night. Although there is site lighting for the substation switching operation, the lighting fixtures are generally only 2-3 meters high, and some equipment that needs to be switched over is installed more than 12 meters above the ground; There is basically no lighting; there is also a situation that when the electrical equipment loses voltage at the station, the lighting in the substation will also be lost, and the accident is often accompanied by bad weather, so the indoor and outdoor visibility is very low during the accident. In the case of several poor lighting conditions, the operator cannot effectively observe whether the equipment operation is in place, and often ends the operation based on experience and sensory judgment, which will lead to poor contact of equipment discharge. Now the operator usually carries a flashlight for night switching operation, but the operator needs to wear insulating gloves with both hands to operate and cannot hold the flashlight, while the guardian not only needs to hold a pen in one hand, and the operation ticket splint in the other hand to monitor the operation, but also use a flashlight to help with the operation It is very inconvenient for people to illuminate, and it will also prolong the switching operation time; in addition, the guardian will give the operator a flashlight to help the operator, and it may cause the guardian to be distracted, and the operation will skip items, miss items, and cause misoperation accidents, resulting in equipment damage and power outages for users , and even system stability damage accidents. Therefore, it is necessary to carry out technological innovation on the lighting during the existing switching operation, and develop a portable lighting device suitable for the night switching operation of the power system transmission, transformation, distribution, and power consumption industries or the handling of substation power loss accidents.
