The invention belongs to the technical field of electrical equipment, and particularly relates to a sealed damp-proof electric meter box. The sealed damp-proof electric meter box comprises a box body. A front baffle of the box body comprises a left plate body, an upper plate body, a right plate body and a lower plate body which are connected end to end, the outer end faces of the left plate body, the upper plate body, the right plate body and the lower plate body are each provided with a groove, the four grooves are internally provided with first rubber sealing strips connected end to end, the first rubber sealing strips are of a hollow structure, and the front end faces of the first rubber sealing strips are in an M shape; a cover plate is hinged to the interior of the groove in the left plate, the outer end face of the cover plate and the outer end face of the front baffle are located on the same vertical face, the inner end face of the cover plate is provided with a second sealing rubber sealing strip connected with the first rubber sealing strips in a contact mode, the outer end face of the second rubber sealing strip is matched with the front end faces of the first rubber sealing strips, and the right end of the cover plate is fixedly connected with the groove in the right plate body. The cover plate and the box body are combined into a full-sealed structure, and the problem that water mist and tidal air enter the box body is solved fundamentally.

The invention discloses a rolling type power equipment electric leakage troubleshooting device and a troubleshooting method thereof. The device comprises a movable mainboard, wherein a supporting guide rail is vertically and fixedly connected to the upper right side of the movable mainboard, a U-shaped frame is slidably connected to the supporting guide rail, and a supporting spring is verticallyand fixedly connected between the U-shaped frame and the inner bottom of the supporting guide rail; a pin roller is arranged on the inner side of the U-shaped frame, an electroprobe is horizontally and fixedly connected to the outer wall of the U-shaped frame, and an electric leakage detection mechanism is arranged on the pin roller. The roller drives the conductive fibers to roll along the arrangement vertical surface of the to-be-detected electrical element, and the single conductive fiber is slender and is combined with the brush-shaped end head of the conductive fibers, so that the contactwith a detection position is facilitated, the detection effect is improved; when electric leakage exists at a certain position, the current is conducted to the electroprobe along elements such as theconductive fiber, so that a worker operating the device can be conveniently reminded of an electric leakage position.

The invention relates to the field of electric power equipment, in particular to a box-type substation, comprising a water collecting mechanism, an outer frame, a mounting bracket, a pressing-down mechanism, a cooling mechanism, a sliding mechanism, a water storage mechanism, a heat dissipating mechanism, a connecting mechanism, a pushing mechanism and a mounting port. Rainwater evaporates from the inside of the main tank on sunny days, the spring returns the main tank, A first copper sheet and a second copper sheet are electrically connected, Further, the electric pushing rod moves the pushing plate forward to realize that the connecting frame drives the connecting plate to rotate the rotating shaft counterclockwise, thereby realizing the opening of ash baffle plates on the surfaces of aplurality of rotating shafts, Heat dissipation is realized. On rainy days, rain water enters into the inside of the main water tank, the spring contracts, the first copper sheet is separated from thesecond copper sheet, the electric push rod is powered off, the pusher plate is moved backward, the rotating shaft rotates clockwise to open the ash baffle plate so as to prevent rain water from entering the mounting frame, and the side contact between the auxiliary water tank and the mounting frame starts to cool down.
