Description

A portable telescopic live working cleaner

technical field

The utility model relates to a tool for live work, in particular to a portable telescopic cleaner for live work.

Background technique

Pollution flashover of equipment will seriously affect the safe and stable operation of the power system, bring voltage fluctuations, and cause short-circuit faults. And if there is an instantaneous fault on the transmission line during pollution flashover, the success rate of relay protection reclosing will be greatly reduced. Reclosing is an important means to restore power supply in the power system due to instantaneous faults, and a reduction in the success rate of reclosing will cause large-scale power outages. At the same time, the discharge arc accompanying pollution flashover may also lead to breakdown and damage of electrical equipment, which not only damages the equipment itself, but also further expands the power outage accident. Pollution flashover accidents directly affect the operation of the power system, seriously reducing the reliability of power supply, and the resulting other national economic losses are immeasurable. Preventing pollution flashover of insulating porcelain bottles is a long-term and important task for power systems.

During the long-term operation of insulators and lightning arresters, the dust particles in the atmosphere deposit on their surfaces to form a pollution layer, which increases the surface conductivity and reduces the insulation performance, while the ash in them retains moisture, which promotes further moisture in the pollution layer, thereby dissolving more Electrolyte, causing flashover discharge on the wetted surface of insulators and arresters, this flashover is called pollution flashover. Since the 1980s, with the rapid development of industrial production, my country's atmospheric environmental pollution has become increasingly serious, causing a sudden increase in power grid equipment pollution flashover accidents. and great loss to the people. Therefore, timely cleaning of heavily polluted insulators and arresters is an important task for the safe operation of power transmission and transformation equipment.

In the past, cleaning methods for heavily polluted insulators included electrified water washing, electrified blowing, and manual cleaning after power failure. Although it has a certain effect, but live water flushing has high requirements on insulation and there are personal safety hazards, so its use is limited; live electric blowing and cleaning will cause secondary pollution to the environment of the substation, and the State Grid Corporation of China does not It is recommended to use the cleaning method with electricity; manual cleaning is not only a heavy workload, but also difficult working conditions. Moreover, it is faced with the problem that the short power outage time and the small number of times limit the cleaning work. And for insulators in high-voltage overhead lines, due to reasons such as long transmission lines, complex terrain, and inconvenient transportation, the use of the above methods is subject to certain restrictions.

In addition, some people in China have developed a portable and reliable insulator live cleaning mechanism. The Chinese Utility Model Patent (ZL Patent No. 98220821.9) discloses a live dust removal operation device. The brush is also equipped with a micro-motor that drives the rotation of the cleaning brush, but the insulating rod of this kind of electrostatic precipitator is easy to rotate by itself, so it is difficult to fix the direction of the cleaning brush during the insulator cleaning operation, and the cleaning effect is greatly reduced. In view of these circumstances, it is an urgent problem to develop a light, reliable, simple and practical insulator cleaning mechanism and solve the above-mentioned cleaning brush direction rotation problem.
