Automatic derusting device and method for field high-voltage bus connector

Abstract

The invention discloses an automatic derusting device and method for a field high-voltage bus connector in the field of power transmission equipment maintenance. One end, to be polished, of the high-voltage bus connector horizontally penetrates through the middle of a polishing device, and the polishing device is fixedly connected with a nut pair through a sliding block; the nut pair and a screw rod are matched; an output shaft of a stepping motor is fixedly connected with the screw rod that is parallel to the high-voltage bus connector; the other end, not needing grinding or derusting, of thehigh-voltage bus connector extends into a support frame, and the support frame is connected with a movable bolt capable of fixing the high-voltage bus connector; an impedance detection module is tightly attached to the outer surface of the high-voltage bus connector and connected with an MCU controller; the polishing device moves back and forth on the high-voltage bus connector to remove dust ofthe high-voltage bus connector; and in combination with the high-voltage bus connector impedance detection technology, whether rust removal is sufficient or not can be judged and analyzed from the detected high-voltage bus connector impedance, and the high-voltage bus connector needing rust removal can be found in time

Description

technical field [0001] The invention belongs to the technical field of electric power transmission equipment maintenance, and relates to a device for derusting a high-voltage bus joint operated in the field. Background technique [0002] The high-voltage bus trunk line replaces the traditional distribution cable with superior performance and becomes the main carrier of power transmission. The main material of the high-voltage busbar is metal material. Since the high-voltage busbar is in the field working environment for a long time, and the field environment is complex and changeable, the metal material is damaged by the surrounding medium, which is called metal corrosion phenomenon, and metal corrosion is the most common corrosion. The shape, especially the high-voltage busbar joints, is extremely susceptible to corrosion due to long-term exposure to the air. Corrosion of high-voltage busbar joints will reduce its mechanical properties such as strength and toughness, destr...

AI Technical Summary

Problems solved by technology

At present, the rust removal methods for high-voltage busbars mainly include manual rust removal and mechanical rust removal. Manual rust removal requires power supply maintenance personnel to climb high-voltage towers and high-voltage busbars. The safety is not high, and there are also problems such as low efficiency and incomplete rust removal. Manual derusting method consumes manpower and material resources, which will bring a lot of inconvenience to maintenance personnel

Mechanical rust removal uses portable battery-type equipment to automatically remove rust. There are problems such as battery exhaustion and insufficient power. The socket power type automatic rust removal equipment needs to build a power supply, which is not suitable for field sites, and the long power lead is not conducive to near electrical work
