Substation ground wire connection indication device

Abstract

A substation ground wire connection indication device comprises a ground stud which is directly inserted in land and makes contact with the ground to form a ground wire of a substation. The portion, exposed out of the land, of the ground wire is connected with the ground wire connection indication device provided with an indication lamp in series. The ground wire connection indication device is connected with a power supply in series and makes contact with another land through a wire, the indication lamp is a light-emitting indication lamp capable of displaying green or red, and if the ground stud makes good contact with the land, the ground wire connection indication device, the power supply and the land form a connection circuit, and the indication lamp is green; otherwise, if the ground stud does not make contact with the land or is virtually connected, the ground wire connection indication device, the power supply and the land do not form the connection circuit, and the indication lamp is red. The device has the advantages of being capable of indicating the connection state of the ground wire, prompting operation and maintenance staff to change ground connection places, being good in ground wire connection through other methods, improving safety and reliability of the ground wire of the substation and the like.

Description

technical field [0001] The invention relates to a grounding wire conduction indicating device of a substation, which belongs to the technical field of electric power safety. Background technique [0002] In the prior art, when the outdoor switches, switch blades and capacitor banks of the substation are overhauled, it is necessary to hang the grounding wire, and the conduction of the grounding wire cannot be seen with the naked eye. Sometimes, it may be a virtual connection, or the grounding conduction is not good, so there will be safety hazards, and more serious situations will threaten human safety. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a device installed on the grounding wire, which can indicate the conduction state of the grounding wire, prompt the operation and maintenance personnel to change the grounding location, or make the grounding wire conduction by other methods...
