Problems solved by technology

[0004] The above-mentioned method of using a generator to provide the required 220V AC power supply for the electric test instrument, because the generator is generally large in size, it is very difficult to transport; the fuel (gasoline, diesel, etc.) required by the generator is not only expensive, but also easy to use. Combustibles are dangerous to a certain extent; power testing instruments require a stable power input, and generators have poor output stability and even serious distortion due to various limitations of their own, which makes the power testing instruments unable to be used well

Abstract

The invention discloses an intelligent emergency power supply, relates to the technical field of power supply of power equipment, and is mainly applied to supplying power to a power test instrument. The intelligent emergency power supply is simple in structure, small in volume and high in portability; electric energy is stored by use of a rechargeable battery, cyclic application is realized, energy is saved, the environment is protected, and the cost is reduced; fuels are not used, and the safety coefficient is high; and output electric signals are stable and distortion-free, and a powerful guarantee is provided for good work of the power test instrument. The main points of the technical scheme are as follows: a charging conversion module converts obtained charging electric signals, charges a battery pack and enables the battery pack to obtain a power supply electric quantity and output power supply electric signals, and a first power supply conversion module converts the power supply electric signals so as to output first power supply electric signals; and a second power supply conversion module outputs second power supply electric signals through conversion.

Description

technical field [0001] The invention relates to the technical field of power supply for electric equipment, in particular to an intelligent emergency power supply. Background technique [0002] Electric power testing instruments are instruments for testing the insulation performance of equipment and the operating status of equipment. They are indispensable instruments for daily maintenance of power grids. Most of the power testing instruments need 220V AC power supply for them to be used normally. However, the power grid is generally laid outdoors, even in remote suburbs, and cannot provide the required power for the testing instruments used. Therefore, it can provide power for the testing instruments. The research and development of 220V AC power supply has become an urgent problem in this field. [0003] At present, the generator is generally used to provide the required 220V AC power supply for the power test instrument, that is, the generator is used to convert the fuel...
