Abstract

The invention provides a ground wire locking device and a locking method thereof. The ground wire locking device mainly comprises a first lock body and a second lock body. The first lock body comprises a first working face, and the second lock body comprises a second working face. A first ground wire fixed mounting clamping piece part and a connection fixing device of a first lock casing are positioned on the first working face. The second ground wire fixed mounting clamping piece part and a connection fixing device of a second lock casing are positioned on the second working face. A two-value RFID chip is provided in an inner cavity of the second lock casing. In application, the first lock body and the second lock body are separately installed on two ends of a temporary ground wire, or the second lock body is installed on the temporary ground wire and the first lock body is installed on another object. When the ground wire locking device is in a locked state, the first lock body and the second lock body can not be separated; that is, the two ends of the ground wire can not be separated or move freely, and can only be unlocked and separated by using a computer key. A function realized by the two-value RFID chip is to provide different RFID chip values. When the RFID chip values are identified by the computer key, whether the first lock body and the second lock body are in the locked state can be known.

Description

technical field [0001] The invention relates to a ground wire lock device and a locking method thereof, in particular to an unlocking device for a temporary ground wire used in a microcomputer anti-misoperation locking system in the field of electric power prevention and electrical misoperation. Background technique [0002] The microcomputer anti-misoperation locking system is a control system used by my country's power system to prevent switching misoperations in the process of power transmission and distribution in power plants and substations. The load pulls and closes the knife switch, prevents the live wire from being connected to the ground wire, and prevents the ground wire from closing the knife switch. Over the years, switching misoperations have repeatedly caused serious accidents in the power system, and it is impossible to compulsorily add the ground wire to the entire anti-misoperation locking system for mandatory management in accordance with the locking equipm...
