Remote control system for transformer station water washing robot for aiming at low-altitude insulator

Abstract

The invention discloses a remote control system for a transformer station water washing robot for aiming at a low-altitude insulator. The remote control system comprises a walking control system and a safety control system. The walking control system comprises a wireless receiving module, a remote control, an on-vehicle controller and an information acquisition module. Wireless equipment is used between the wireless receiving module and the on-vehicle controller, and wireless equipment is used between the on-vehicle controller and the information acquisition module, thereby forming a WIFI network and realizing data interaction among the three modules. The safety control system utilizes real-time control for the operation process of the robot by means of an ultrasonic sensor, a magnetic field ranging sensor, a water resistance ratio sensor and a water pressure sensor which are mounted on a pan / tilt. The remote control system realizes real-time online monitoring for the water resistance, the water pressure and the water column length, thereby ensuring high insulating property of a robot body and live equipment of the transformer station in the water washing process, and effectively improving safety in the water washing process.

Description

technical field [0001] The invention relates to a remote control system for a substation water washing robot aimed at low-altitude insulators. Background technique [0002] With the increasing pollution of the air environment, pollution flashover accidents of power grid equipment have increased, seriously affecting the safe operation of power grid equipment. Substation insulators are exposed to the external environment for a long time, and dirt is easy to deposit on the surface. These dirt are prone to pollution flashover accidents when they are damaged by bad weather. According to statistics, insulation flashover accidents caused by pollution have now taken the second place in the total number of power grid accidents. From 1971 to 1994, there were 1,768 pollution flashovers in 35-500kV power generation and substations nationwide. The washing operation of insulators with live water can improve the reliability of power supply, reduce power failure losses, and ensure the safe...

Problems solved by technology

[0003] 1. Most of the cleaning methods are carried out by cleaning technicians who enter the site with hand-held cleaning equipment. Manual cleaning not only depends on the weather conditions, but also requires cleaning personnel to have a high technical level and skilled operation procedures. Standardized safety protection to avoid safety accidents caused by short-circuit current, causing casualties. This type of operation method has potential safety hazards;

[0004] 2. Manual operations are faced with many problems such as high labor intensity, low efficiency, and low level of automation;

[0005] 3. It is impossible to monitor the water resistance rate, water pressure, and water column length in real time, to modify the operating status of the robot in real time, and to guarantee the insulation performance of the robot body and live equipment in the substation during the water flushing process;
