The invention discloses a safety-type maintenance power box which is provided with a box body and a box door. The power box is characterized in that one side of the box body is provided with a wire outlet opening and two guiderails, which extend out of the box body, are installed at the front side and the rear side of the wire outlet opening. A sliding door is installed on the guiderails in a sliding manner. The safety-type maintenance power box is simple in structure and convenient to use; the box door can be closed when a temporary power supply is lap jointed so that it can be prevented that small animals jump in and a short circuit is caused because of erosion of rain; cut-off the power supply, caused by error operations of other construction personnel can also be prevented; cable connection in the lap joint of the temporary power supply is firmer; and the safety-type maintenance power box is mainly used as a floor-type maintenance power box of a transformer substation.
Description
technical field [0001] The invention relates to the improvement technology of a floor-type maintenance power supply box of a substation, in particular to a safe maintenance power supply box. Background technique [0002] At present, the traditional inspection power supply box has no cable inlet and outlet, and the door cannot be closed when the temporary power supply is overlapped. Small animals are prone to enter the box and rain erosion may cause short circuits. After the power box is wired, the cables cannot be fixed, and short circuits are prone to occur. Therefore, it is very necessary to design a maintenance power supply box that can well solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the traditional overhaul power box has no cable inlet and outlet, the box door cannot be closed when the temporary power supply is lapped, and the situation that the power supply cannot be randomly lapped a...
