Transformer substation live washing robot for low-air insulators and method

Abstract

The invention discloses a transformer substation live washing robot for low-air insulators and a method. The robot comprises a vehicle walking mechanism, a power assembly, a perpendicular lifting mechanism, a water gun washing mechanism, an electrical control system and the like. The vehicle walking mechanism is of a caterpillar band type moving chassis structure. A diesel engine is adopted in the power assembly for providing power, and the power assembly is installed on a moving chassis. The perpendicular lifting mechanism is connected to the front end of the vehicle walking mechanism and provided with a two-level telescopic arm, and an upper arm of the two-level telescopic arm is connected with a work cradle head of the water gun washing mechanism through insulation supporting columns. The insulators of a transformer substation can be washed through the robot instead of manual work, an operator is located in a safe region, the safety of the operator is guaranteed, labor intensity is relieved, the washing efficiency is improved, the automation level is increased, and the positive revolutionary effect on the washing operation manner of the transformer substation in China is achieved.

Description

technical field [0001] The invention relates to a substation live water washing robot and method for low-altitude insulators. 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 personnel to have a high technical level and skilled operation procedures. Standardized safety prot...

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;

[0005] 3. The technical requirements for electrified water flushing are relatively high, and affected by various factors such as the environment, pollution accumulation, equipment creepage distance, and equipment layout, equipment flashover is prone to occur during manual flushing;

[0006] 4. Considering that the live water flushing operation 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;

[0007] 5. Most of the existing water washing robots are designed for cleaning insulators over 8m in length. This type of water washing robot is not suitable for substation post insulators below 8m and located at low altitudes.
