The electrification water washing auxiliary flushing robot system is characterized by comprising a water washing system and an auxiliary flushing robot; the water washing system comprises a pure water preparation system and a high-pressure jetting system; the pure water preparation system is connected with the high-pressure jetting system, and the high-pressure jetting system is connected with the auxiliary flushing robot through a high-pressure pipe; and the auxiliary flushing robot system comprises a vehicle body running gear, a vertical lifting mechanism, a water gun flushing mechanism, a power assembly and an electrical control system. The electrification water washing auxiliary flushing robot system has the beneficial effects that manual work is replaced with the robot to complete washing operation of insulators of the transformer substation, an operator is located within a safety area, the safety of the operator is guaranteed, the labor intensity is reduced, the washing efficiency and the automation level are improved, and positive revolution effect on water flushing operation mode of the transformer substation in China is achieved.

Description

technical field [0001] The invention relates to the field of live water flushing robots for substations, in particular to a mobile self-supply type substation live water flushing auxiliary flushing robot system and method. Background technique [0002] 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. The washing operation of insulators with live water can improve the reliability of power supply, reduce power failure losses, and ensure the safety of substations and transmission lines. At the present stage, the washing operation of substation insulators mainly has the following shortcomings: [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 per...

AI Technical Summary

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; the technical requirements for electrified water flushing are relatively high, and are affected by various factors such as the environment, pollution, equipment creepage, and equipment layout. Equipment flashover is prone to occur during flushing;

[0005] 3. Considering that the flushing operation of live water is affected by various aspects such as flushing angle and water pressure, manual operation sometimes cannot completely flush away the dirt on the outer insulating surface of the equipment

For areas where substation equipment is relatively concentrated, large-scale washing equipment cannot pass through the equipment to enter the contaminated area for washing, and manual washing operations have the above-mentioned many disadvantages, which brings greater difficulties to the cleaning of insulators

[0006] 4. The existing water washing equipment has low automation, low efficiency, high energy consumption, and great potential safety hazards

In particular, the conductivity of pure water is the most important factor affecting the flushing of charged water. If the conductivity does not meet the standard, it will cause serious damage to equipment and personal safety.
