Hand-held multifunctional maintenance power supply device

Abstract

The invention discloses a hand-held multifunctional maintenance power supply device comprising a box body and an electrical combination unit. The box body consists of a side plate I alternating-current panel and a side plate II direct-current panel. The electrical combination unit that is used for power distribution for the side plate I alternating-current panel and the side plate II direct-current panel includes a storage battery group, an inversion unit, and a discharging unit. The storage battery group is used for providing a first voltage amplitude output for the inversion unit and providing a second voltage amplitude output for the discharging unit. According to the invention, the box body can be carried conveniently; restriction by an environment is eliminated; and because of the functions, a power demand of the multi-group maintenance power supply at the power production working field can be satisfied.

Description

technical field [0001] The invention relates to a maintenance power supply device, in particular to a portable multifunctional maintenance power supply device used in the field of electric power production. Background technique [0002] The maintenance power box of the existing substation is usually fixed. During the maintenance and test work in the station, the work team will find that the distance between the maintenance power box and the work site is relatively long, and it is very cumbersome to switch the power line, resulting in a long operation time. Affect the work progress and efficiency on site. [0003] Especially when working outside the substation, it is particularly prominent. When working in multiple teams, a large number of temporary power supply panels are required, and frequent power connection work increases the labor intensity of the staff.

Problems solved by technology

[0002] The maintenance power box of the existing substation is usually fixed. During the maintenance and test work in the station, the work team will find that the distance between the maintenance power box and the work site is relatively long, and it is very cumbersome to switch the power line, resulting in a long operation time. Affect work progress and efficiency on site

[0003] Especially when working outside the substation, it is particularly prominent. When working in multiple teams, a large number of temporary power supply panels are required, and frequent power connection work increases the labor intensity of the staff. At the same time, the power cord is lengthened and the external connection The power supply has certain hidden dangers to the safety of on-site construction, and it no longer meets the current conditions of use on the job site

[0004] The maintenance power supply box in the prior art usually only plays the role of a distribution box, and cannot work independently from the AC power supply. This type of maintenance power supply box is disclosed in the patent documents CN103872599B, ​​CN103825350A, CN104734027A, and CN105140788A. When working outside the substation, it still An external AC power supply is required, which is inconvenient to use and has potential safety hazards
