The present invention is further described with reference to the accompanying drawings and examples：
In the embodiment shown in Fig. 1~Fig. 3, the electromagnetic type rain-proof electric power cabinet includes cabinet 1, is fixed in the cabinet 1
There is electric frame 2；The both sides of the cabinet 1 are symmetrically arranged with vent window 3；The vent window 3 is in shutter, by from top to bottom
The bar shaped rain cover piece 31 of equidistant parallel is formed；The rain cover piece 31 is made up of silicon steel sheet, and its both ends is articulated in by spring shaft 32
In axle sleeve 320 in the side wall of the cabinet 1；Under the constraint of spring shaft 320, when rain cover piece 31 is not acted on by magnetic force,
The side of each rain cover piece 31 and cabinet 1 is set to keep a larger inclination angle.
The upper and lower sides of the vent window 3 are respectively equipped with the upper electromagnet 41 parallel with the rain cover piece, lower electromagnet 42；Institute
The outside for stating cabinet 1 is provided with rain sensor（It is not shown）；The rain sensor is when sensing extraneous rainwater, described in triggering
Upper electromagnet 41, lower electromagnet 42 are connected, and during the energization of upper electromagnet 41, lower electromagnet 42, heteropole is relative, near so as to be formed
Like the magnetic field parallel to cabinet side wall.
When above-mentioned electromagnetic type rain-proof electric power cabinet is under non-rainy day environment, the upper electromagnet 41, the no power of lower electromagnet 42,
Each not magnetic field force induced effect of the rain cover piece 31, under the constraint of the spring shaft 32, keep relatively large with the side of cabinet 1
Inclination angle, i.e., state as shown in Figure 1；And in rainwater environment, because the upper electromagnet 41, lower electromagnet 42 are powered, and it is different
Extremely relative, so as to form the magnetic field for being approximately parallel to cabinet side between upper and lower electromagnet 41,42, each rain cover is drawn in the magnetic field
Piece 31 rotates, and each rain cover piece 31 is rotated to angle as parallel with cabinet side as possible, i.e. rain cover piece 31 and keeps phase with cabinet 1
To less inclination angle, i.e., state as shown in Figure 3；Enter electric power cabinet so as to suppress rainwater.When being disappeared to rainwater, upper electricity
Magnet 41, lower electromagnet 42 power off, magnetic field eliminate, then each rain cover piece 31 resets under the restoring force of spring shaft 32, but with cabinet 1
