An automatic control catenary hanging ground wire device and its control method

Abstract

The invention discloses an automatic control catenary hanging ground wire device, which includes a multi-section electric push rod, the bottom end of which is connected to PLC through an intermediate relay, and the other end is vertically installed with an insulating plate, and the insulating plate is installed with a conductive plate through a spring , the conductive plate is connected with annealed copper wire a, the other end of annealed copper wire a is connected with a voltage divider, the other end of the voltage divider is connected with an annealed copper wire b, the other end of an annealed copper wire b is connected with a grounding metal plate, grounded A first electromagnet is fixed vertically on the metal plate, a 7-type bracket is arranged at the bottom of the voltage divider, a bottom plate is arranged at the bottom of the bracket, a wedge block and a control switch are arranged on the side of the bracket in turn, and a second electromagnet is installed on the wedge block. The invention also discloses a control method of the automatic control catenary hanging grounding wire device. It solves the problems in the prior art that the workers have inaccurate electrical inspection, the grounding wire is not in place, the operation is not in accordance with the prescribed sequence, and the work intensity is high.

Description

technical field [0001] The invention belongs to the technical field of railway catenary safety tools, and in particular relates to an automatically controlled catenary hanging grounding wire device, and also relates to a control method of the above-mentioned automatic control catenary hanging grounding wire device. Background technique [0002] Hanging the ground wire is an important safety measure for catenary power outage maintenance. It can quickly eliminate the residual charge of the power outage line and reduce the induced voltage caused by the adjacent non-power outage line. It is also a safety barrier to protect the maintenance personnel and prevent sudden calls from causing harm to the human body. . All electrical inspection and grounding operations are carried out by 2 people; before power failure maintenance, it is necessary to check whether the status of the electrical inspection meets the requirements; when installing the ground wire, first ground one end of the ...
