Forced locking-type ground wire pile

Abstract

The invention relates to a forced locking-type ground wire pile which comprises a ground connector, a control cabinet and an unlocking key. The ground connector and the control cabinet are connected in a left-right mode. The ground connector is made of connective materials. A groove is formed in one side wall of the ground connector, and a circular hole is formed in the side wall, adjacent to the side wall where the groove is formed, of the ground connector. The circular hole is communicated with the top of the groove. An electromagnetic iron core, a digital encoder, a clamping pin, a diverter switch, a rocker, an unlocking hole and three binding post sets are arranged inside the control cabinet, wherein the digital encoder controls the electromagnetic iron core to be powered on or powered off, and the clamping pin is sleeved with a reset spring. The forced enclosed-type ground wire pile has the two functions of microcomputer mistaken locking prevention and electrical locking, the two functions complement each other, reliability of the misoperation prevention is improved, and electrified ground wire and ground wire switching-on power supply can be effectively prevented; meanwhile, when devices like a disconnecting switch are overhauled, it is ensured that switching-on and switching-off of the disconnecting switch can be electrically tested without removal of the ground wire due to induced electricity or other reasons.

Description

technical field [0001] The invention relates to a forced locking type ground wire pile. Background technique [0002] The power system regulations clearly point out that: the hanging point of the operation ground wire in the substation and distribution station should be clearly set in advance, and the mandatory locking should be realized. Regarding the error prevention of the ground wire, the method of locking the ground wire pile is usually used to lock it under the conditions of hanging and removing the ground wire. This blocking logic judgment is completed by the microcomputer anti-mistake system, that is, it is completely completed by computer program software. [0003] The existing conventional locking method belongs to "soft locking". Once the error prevention logic goes wrong or the microcomputer error prevention system itself is abnormal, it will cause misoperation accidents; at the same time, if the operator pulls out the code lock before it is opened The computer...

Problems solved by technology

[0003] The existing conventional locking method belongs to "soft locking". Once the error prevention logic goes wrong or the microcomputer error prevention system itself is abnormal, it will cause misoperation accidents; at the same time, if the operator pulls out the code lock before it is opened The computer key, the computer key will show that the next step can be performed. If the operator does not repeat this step or directly proceed to the next step, there will be a problem of "going empty", which will also cause misoperation accidents.
