On-site air-drying dehumidification device and method of live-working insulating tools

Abstract

The invention discloses an on-site air-drying dehumidification device and method of live-working insulating tools. The device comprises a rectangular frame and an outer cover. The outer cover is arranged on the surface of the rectangular frame. A transverse rod is arranged in the middle of the rectangular frame. A dehumidifier and a hot air heating device are arranged at the bottom of the rectangular frame. The hot air heating device and the dehumidifier are connected with a control device. A controller comprises a temperature measuring probe, and measures the temperature ranging from minus 9DEG C to 99 DEG C. A thermistor is adopted for the temperature measuring probe. The temperature measuring probe has the accuracy of + / - 1 DEG C. The device can be quickly installed or detached on site, is convenient to carry about, can carry out quick, efficient and comprehensive drying treatment for dehumidification on insulating tools and instruments on site, and it is guaranteed that the live-working tools are safe to use to serve work for improving power supply reliability.

Description

technical field [0001] The invention relates to a dehumidification device, in particular to an on-site air-drying dehumidification device for insulating tools for live work, and also relates to the dehumidification method. Background technique [0002] According to the requirements of live working technical guidelines, electric safety work regulations, etc. and the actual safety requirements of live working work: before use, insulated tools for live working must undergo visual inspection and pass the test before they can be used. After that, the insulation performance drops sharply, which cannot meet the safety requirements of the operation. [0003] There are many types of insulating tools for live work, and the materials are different. According to the material texture, there are mainly soft insulating tools and hard insulating tools.

AI Technical Summary

Problems solved by technology

[0002] According to the requirements of live working technical guidelines, electric safety work regulations, etc. and the actual safety requirements of live working work: before use, insulated tools for live working must undergo visual inspection and pass the test before they can be used. After that, the insulation performance drops sharply, which cannot meet the safety requirements of the operation.

[0003] There are many types of insulating tools for live work, and the materials are different. According to the material texture, there are mainly soft insulating tools and hard insulating tools. Soft insulating tools include insulating blankets, insulating clothes, insulating mats, insulating gloves, etc. Hard insulating tools such as Operating rods, insulation boards, etc.; to ensure the safety of live work before use on site, the inspection, cleaning and insulation testing of insulation tools must be carried out, but because the insulation tools used on site are affected by weather and air humidity, there is currently no A technology and method that can heat and dehumidify insulated tools and appliances outside the tool warehouse, and restore the insulation performance of the tools and appliances. When the working tools are damp or used for many days to absorb moisture, the insulation performance is reduced and the work has to be stopped

It must be replaced or brought back to the tool warehouse of the unit for baking and dehumidification, which will affect the work of the next day. Since the operating points are in various counties or towns, it will cause personnel and vehicles to go back and forth, increase the cost of unit line maintenance and elimination of defects, and require power supply reliability. Reasons for damp or reduced insulation performance of live working tools:

[0004] 1. The weather changes suddenly during the rainy season, and it is too late to remove the live working equipment, and the tools are wet by the rain;

[0005] 2. The humidity in the working environment is relatively high, and the tools and appliances absorb moisture after long-term use, especially insulated ropes, hollow insulated operating rods, etc.;

[0006] 3. The operating points are many and wide, and the tools and appliances cannot be taken back to the tool warehouse for baking and dehumidification after many days of use. After testing, the insulation performance does not meet the use requirements.
