Double-insurance safety measure belt for overhauling secondary equipment of transformer substation

Abstract

A double-insurance safety measure belt for overhauling secondary equipment of a transformer substation is disclosed in the invention, and comprises a belt strip, a connecting block and an auxiliary belt, the belt strip and the auxiliary belt are fixedly connected, a connecting hole is formed in the side wall of the connecting block, the belt strip penetrates through the connecting hole, a connecting plate is arranged in the connecting hole, a first spring is fixedly connected to the lower side of the connecting plate, the other side of the first spring is fixedly connected with the connecting hole, a plurality of protrusions are arranged on the side, close to the belt strip, of the connecting plate and are in contact connection with the belt strip, a connecting groove is formed in the left side of the connecting block, the belt strip penetrates through the connecting groove, a moving plate is arranged on the lower side in the connecting groove, and a second spring is fixedly connected to the side, away from the belt strip, of the moving plate. The tail end of the belt strip can be fixed, and a special connecting device is arranged, so that the auxiliary belt is more convenient to mount and dismount, simple to operate and high in practicability.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a double insurance safety measure belt for substation secondary equipment maintenance. Background technique [0002] The substation refers to the place where the voltage and current are transformed, received and distributed in the power system. The substation in the power plant is a step-up substation. Its function is to boost the power generated by the generator and feed it to the high-voltage power grid. The electrical equipment in the substation is divided into primary equipment and secondary equipment. The secondary equipment of the substation refers to the equipment that measures, monitors, controls and protects the operating conditions of the primary equipment and the system. It mainly consists of relay protection devices, Automatic devices, measurement and control devices, metering devices, automation systems, and DC equipment that provide power for secondary equipment...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: belt tail can be produced in the connection process, and these belt tails are placed on the belt at will, and the normal working state of movie star staff, and in In the auxiliary belt, the fixing parts fixedly connected with it are relatively simple and cannot be replaced, and a double insurance safety measure belt for substation secondary equipment maintenance is proposed.
