AI Technical Summary

Technical Problem

During the power supply process of substation maintenance, the contact part between the wire and the high-voltage wire is easily affected by rainfall or winter rain, affecting the safety of power withdrawal.

Method used

A substation maintenance and power supply connection device is designed, including components such as horizontal frame, plug block, stopper, mounting cylinder, guide groove, spring, flexible strip, etc., to protect the contact between the docking wire and the high-voltage line through the horizontal frame, and to use the spring and the top rod to achieve automatic connection between the terminal piece and the high-voltage line, and the card frame is used to perform secondary shading to improve its applicability in rainy days.

Benefits of technology

The device ensures the stability and safety of the high-voltage line on rainy days through automatic connection and secondary shading, and is easy to disassemble. It is suitable for long-term or short-term power withdrawal, especially for temporary power withdrawal and power supply after high-voltage power recovery in disaster areas.

Abstract

The invention provides a power transformation maintenance power supply connecting device and method, and relates to the technical field of high-voltage power taking, the power transformation maintenance power supply connecting device comprises a transverse frame, the two ends of the transverse frame in the length direction are symmetrically arranged in structure, a plug block is inserted into the middle of the transverse frame, a check block is fixedly connected to the lower side face of the plug block, and a mounting cylinder is fixedly connected to the lower side face of the transverse frame; the upper end of the mounting cylinder spans the two sides of the check block, a cavity for containing the check block is formed in the lower side of the middle of the transverse frame, guide grooves are formed in the positions, on the two sides of the cavity, of the transverse frame in the length direction, and springs are arranged in the guide grooves. The contact position of the wiring sheet and the high-voltage wire is protected through the transverse frame, in the using process, after the inserting plate is separated from the transverse frame, automatic connection of the wiring sheet and the high-voltage wire can be completed through cooperation of the spring and the ejector rod and the flexible strip, the contact position is secondarily shielded through the clamping frame, and the wiring sheet can be better suitable for rainy days and is convenient to disassemble.
