The beneficial effects of the utility model: this utility model is by being provided with top cover at casing top, and top cover passes through
Latch is connected fixing with casing horizontal wall, and latch connects electric magnet by spring, arranges axis in the middle part of casing
Running through top cover and portable plate, portable plate is placed on the triangular hill of casing vertical wall, portable plate and level
Lower contact switch and upper contact switch it is respectively equipped with on wall, when the gas in casing drastically expands, upwards jack-up
Portable plate, makes lower contact switch contact with upper contact switch, and electric magnet is energized, and latch is fully entrained casing
Horizontal wall in so that the upwards jack-up top cover of the gas in casing, release rapidly gas, discharge pressure,
Pressure release speed is fast, prevents switch cubicle from exploding, safety and stability, it is ensured that the safety of operator, effectively prevent
Huge potential safety hazard and economic loss.
Accompanying drawing explanation
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of decompression anti-explosion device for switch cabinet, including switch cubicle
Casing 1, casing 1 has horizontal wall 11 and the vertical wall 12 of four sides at top, and shell 1 top is provided with circle
Shape top cover 2, top cover 2 is connected with horizontal wall 11 by being evenly distributed on four latches 3 of its week side, latch
3 one end are inserted in top cover 2, and the other end connects electric magnet 5, spring 4 and the equal position of electric magnet 5 by spring 4
Internal in the horizontal wall 11 of shell 1.
Being equipped with triangular hill 6 inside the vertical wall 12 of casing 1 four side, triangular hill 6 is provided with work
Dynamic plate 7, is provided with axis 8 in the middle part of casing 1, axis 8 extends vertically through top cover 2 and portable plate 7, top cover 2 He
Portable plate 7 is all slidably connected with axis 8, and axis 8 top is provided with baffle plate 9.
Portable plate 7 is provided with lower contact switch 21, below the horizontal wall 11 of casing 1 connect have with under contact out
Closing the upper contact switch 22 of 21 correspondences, lower contact switch 21 and upper contact switch 22 are all electrically connected with electric magnet 5
Connecing, when contact switch 21 contacts with upper contact switch 22 instantly, electric magnet 5 is energized.
Utility model works principle: when inside switch cabinet element failure, substantial amounts of heat will be produced
Amount, the gas in casing 1 can drastically expand, upwards jack-up portable plate 7, make lower contact switch 21 and on connect
Touching switch 22 contact, electric magnet 5 is energized, and is fully entrained in the horizontal wall 11 of casing 1 by latch 3, from
