Description

Mobile multi-function maintenance power box

technical field

The utility model relates to a power supply box, in particular to a mobile multifunctional maintenance power supply box, which belongs to the field of power distribution equipment.

Background technique

The traditional fixed maintenance power box in the station has no power cord inlet and outlet, and the box door cannot be completely closed when the maintenance power is connected, which may easily cause rain, snow or other foreign objects to enter the box and cause a trip hazard. At the same time, due to the limited number of outgoing lines of the maintenance power box branch in the station, on-site operators have problems such as unauthorized access to the maintenance power supply, repeated disconnection of the power supply, etc., resulting in confusion in the use of the on-site maintenance power supply, bringing safety hazards to personnel and equipment. It can only be judged by the mechanical position of the control switch to check whether the outgoing line of the power supply box is charged. The distance between the terminal posts is relatively close, and there is no insulation protection measure between them, so there is a risk of electric shock if people touch the terminals by mistake. At present, high-current and high-power equipment such as welding machines, cutting machines, and some oil-resistant pressure machines used in the maintenance work of the electric power industry do not meet the load requirements of the power box for on-site maintenance.
