Description

Auxiliary heat dissipation and dehumidification device used on insulated bucket arm trucks

technical field

The invention relates to the technical field of electric power maintenance equipment, in particular to an auxiliary heat dissipation and dehumidification device used on an insulated bucket truck.

Background technique

Electricity is an indispensable energy source for the production and life of human society, and it is the material basis for survival. Uninterrupted safe and reliable power supply is a great responsibility. The working environment of the live distribution network is dense and complex. The power distribution facilities are dense and complex. The interphase distance and the distance to the ground of the three-phase conductors are small. It is very easy to cause interphase short circuit and single phase grounding, resulting in personal electric shock and equipment short circuit accidents. In the middle potential operation method, insulating protective equipment must be worn. Among them, the important protective equipment insulating clothing is mainly made of ethylene-vinyl acetate copolymer material (EVA), which is composed of 20 layers of insulating materials, and its outer layer is highly hydrophobic and moisture-proof. . The material with high flashover voltage along the surface and low leakage current, and its lining is also made of strong hydrophobicity and good moisture resistance. It is made of materials with high layered breakdown voltage. The problem is prominent, and there are the following outstanding safety hazards in use:

1. When conducting live work in hot season and high temperature and high humidity environment, the workers will cause poor heat dissipation, profuse sweating, and in severe cases, central nervous system dysfunction, sweat gland failure and excessive loss of water and electrolytes will occur. Acute disease of heat stroke and cardiovascular dysfunction, and even heat stroke with a high fatality rate.

2. Poor heat dissipation during operation in high temperature weather will cause the operator to have headaches, dizziness, thirst, sweating, weakness and soreness of the limbs, inattention, uncoordinated movements, etc., resulting in operational errors resulting in electric shocks, equipment damage and other electrified accidents.

3. When working at a low temperature, although the problem of sweating a lot is weakened, due to the airtight characteristics of insulating protective clothing, the sweat in the work cannot be discharged, which will cause the work clothes to become wet, causing work intermittently or after the end of the work. People caught cold and sick.

4. When the appliance is sweating during operation, it is easy to breed bacteria due to humidity and airtightness, resulting in an unpleasant and extremely unpleasant odor, which affects normal use and storage.

At present, there are cooling clothing and cooling belts for high temperature work at home and abroad, and they are widely used in all walks of life. They mainly include small fan air conditioning clothing, liquid water-cooled type, air pump blowing ventilation vest, fan belt and other products. In terms of the particularity of live work, there are still some problems. For example, the insulating clothing is made of special materials and is relatively heavy. The operator must tie the seat belt, resulting in a small space inside the clothing and the air is not smooth. By blowing the fan around the waist to expand the clothing, the hot air is discharged from the neckline), fan belts and other equipment cannot effectively make the air flow into the body and flow, which cannot achieve the purpose of gas flow replacement and cooling; The temperature inside the clothes is not breathable but cannot effectively remove moisture, which solves the problem of "wet clothes" and has no use value when the temperature is low; at the same time, the high-pressure air pump blowing vest can effectively bring cool air into the body of the operator through the vest , but the high-pressure air pump has a potential explosion safety hazard in a high-voltage working environment. Because it must be equipotential and can only use batteries, the air pump pressurized gas storage not only consumes a lot of power, but also has problems such as large size, inability to install, and high noise; Therefore, it cannot be applied in the aforementioned environment.
