China has put forward the requirements of five prevention in 1990 for electrical equipment, and the regulations (the article 1990: No. 1110) stipulate the principles of management, operation, design and use of electrical anti-misoperation. The five prevention means that the isolating switch is prevented from being pulled and closed by mistake under the condition of load; the circuit breaker is prevented from being pulled and closed by mistake; the switch-on of a grounding wire or a grounding knife switch is prevented; prevent the electrified ground wire hanging or closing the earthing knife switch; prevent the wrong entering into the electrified interval. The realization of the electric five-prevention function is one of the important measures of electric power safety production, and the design principle of the anti-misoperation device is as follows: the high-voltage electrical equipment which may cause misoperation is provided with an anti-misoperation device and a corresponding anti-misoperation electrical locking loop. The five-prevention system generally comprises an anti-misoperation expert system and is generally arranged in a computer host; the five-prevention system also comprises a computer key, a computer key adapter and other locks and accessories, wherein the computer key is the core of the five-prevention system. The existing patent document with publication number CN206322618U provides a novel five-prevention computer key, and the device can realize the lighting function of the five-prevention computer key through an LED lamp arranged at the top of a shell, effectively solves the problem that the computer key is not easy to align to a lock hole during night operation, and improves the working efficiency. Although the device has more beneficial effects, the following problems still exist: when using the computer key, need restrict unblock axle male angle through the location axle, just can open the tool to lock, and current location axle is circular, when the cooperation is unlocked the axle and is inserted the tool to lock on, is difficult to align the pore, can bring inconvenience for the user. In view of this, we propose a transformer substation temporary ground wire anti-false locking management device.
