Thermal insulation method and thermal insulation apparatus for transformer substation portable electronic device battery

Abstract

The present invention relates to a thermal insulation method and a thermal insulation apparatus for a transformer substation portable electronic device battery, and belongs to the technical field of power supply equipment. The technical scheme comprises that: an electric heating film (1) and thermal insulation cotton (7) are arranged inside a apparatus fabric sleeve (8), the apparatus fabric sleeve is arranged inside an elastic transparent plastic sleeve (9), one outer surface of the apparatus fabric sleeve and one inner surface of the elastic transparent plastic sleeve are tightly and integratedly fixed, a gap exists between the other outer surface of the apparatus fabric sleeve and the other inner surface of the elastic transparent plastic sleeve, a portable electronic device is inserted into the gap, a battery side of the portable electronic device is tightly close to the apparatus fabric sleeve, and a keyboard side or a screen side of the portable electronic device is tightly close to the elastic transparent plastic sleeve. According to the present invention: a structure is simple, a maintenance cost is low, a continuous thermal insulation effect can be provided for the transformer substation portable electronic device battery under an outdoor low temperature state, and use efficiency and a service life of the transformer substation portable electronic device battery under an outdoor low temperature state can be improved.

Description

technical field [0001] The invention relates to a battery heat preservation method and heat preservation device of portable electronic equipment in a substation, belonging to the technical field of power supply equipment. Background technique [0002] With the continuous application of advanced technology, more and more portable electronic devices are used in daily substations, such as five-proof computer keys, infrared thermometers, equipment inspection instruments, etc. These electronic devices all need batteries (rechargeable lithium-ion batteries) to supply power during normal operation, and the continuous working time is relatively long, but the capacity and life of the batteries are greatly affected by the external temperature. The activity of lithium batteries drops greatly at low temperatures. At around 25 degrees Celsius, the effective capacity of the battery is the largest. For every 10 degrees Celsius lower, the battery capacity drops by 10%. When the temperature...

AI Technical Summary

Problems solved by technology

When the temperature is low in winter, if the electronic equipment is used outdoors for a long time, the capacity of the lithium battery will be greatly reduced, which not only affects the use time of the electronic equipment, but also reduces the service life of the battery

At present, the heat preservation measures for electronic equipment in the background technology are only thermal insulation sleeves. The disadvantages of thermal insulation sleeves are: 1. Thermal insulation sleeves are passive insulation, which can only ensure that the heat loss of electronic equipment is small. The thermal insulation sleeve itself cannot generate heat. It works; 2. When using portable electronic devices, you need to remove the insulation cover, otherwise it will affect the use of viewing the screen of the electronic device or some buttons
