Remote control system for live-line water flushing robot of transformer station and method of system

Abstract

The invention discloses a remote control system of a live-line flushing robot of a transformer station and a method of the system. The system comprises a walking control system and a safety control system, the walking control system comprises a wireless reception module, a remote controller, a vehicle-mounted controller and an information collection module, wireless devices are used between the wireless reception module and the vehicle-mounted controller and between the vehicle-mounted controller and the information collection module respectively to establish a WIFI network and realize data interaction among the modules, and the safety control system uses ultrasonic, magnetic-field range finding, water resistance and hydraulic pressure sensors mounted on a holder to realize real-time monitoring for the operation process of the robot. Thus, the water resistance, the hydraulic pressure and the length of a water column can be monitored online in real time, the insulation performance of the robot body and live-line equipment of the transformer station is ensured, and the safety of water flushing is effectively improved.

Description

technical field [0001] The invention relates to a remote control system and method for a substation charged water washing robot. 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 safety of substati...

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;
