Referring to fig. 1 and 2, there is provided a high-efficiency voltage-relief protection switch cabinet, comprising: the cabinet body, the cabinet body divides into handcart room 110, bus-bar room 120 and cable chamber 130 through the baffle, the top of the cabinet body is provided with pressure release roof 200, first pressure release passageway 101, second pressure release passageway 102 and third pressure release passageway 103, handcart room 110 communicates through first pressure release passageway 101 and pressure release roof 200, bus-bar room 120 communicates through second pressure release passageway 102 and pressure release roof 200, cable chamber 130 communicates through third pressure release passageway 103 and pressure release roof 200, pressure release roof 200 pass through the nylon bolt with the top of the cabinet body is connected, pressure release roof 200 is equipped with first through-hole array 210, second through-hole array 220 and third through-hole array 230, the unit through-hole of first through-hole array 210, the unit through-hole of second through-hole array 220 and the unit through-hole of third through-hole array 230 all are provided with the nylon stopper, first through-hole array 210 is located first pressure release passageway 101, the second through hole array 220 is located on the second pressure relief passage 102, and the third through hole array 230 is located on the third pressure relief passage 103.

The cabinet body refers to a component body which is formed by enclosing sheet metal and is provided with an accommodating cavity, and the accommodating cavity is used for accommodating corresponding electrical elements of the switch cabinet. The accommodating cavity is divided into a handcart room 110, a bus room 120 and a cable room 130 by partition boards, wherein the handcart room 110 is used for accommodating high-voltage electric switches, such as: a low oil type breaker, a vacuum type breaker or a sulfur hexafluoride breaker. The bus bar compartment 120 is used for accommodating bus bars. The cable chamber 130 is used for accommodating cables.

Because the cabinet body has certain leakproofness, so in order to avoid the electric elements to take place the short circuit and form high temperature high pressure gas and cause the injury to the human body, so need set up the pressure release protection mechanism in the cabinet body. The high-temperature and high-pressure gas is discharged directionally through the pressure relief protection mechanism so as to protect the human body from being injured. For this purpose, the present embodiment provides a first pressure relief channel 101, a second pressure relief channel 102 and a third pressure relief channel 103. The first pressure relief channel 101 is mainly used for relieving high-temperature and high-pressure gas generated by the handcart chamber 110, the second pressure relief channel 102 is mainly used for relieving high-temperature and high-pressure gas generated by the bus chamber 120, and the third pressure relief channel 103 is mainly used for relieving high-temperature and high-pressure gas generated by the cable chamber 130. The first, second and third bleed passages are all connected to the pressure head plate 200. The pressure relief top plate 200 is connected with the top of the cabinet body through a nylon bolt. When an accident occurs, the high-temperature and high-pressure gas can melt the nylon bolt, so that the pressure relief top plate 200 can be separated from the top of the cabinet body. In order to make the high-temperature and high-pressure gas more efficiently pressure-relief from the first pressure-relief passage 101, the second pressure-relief passage 102, and the third pressure-relief passage 103. A first through hole array 210, a second through hole array 220, and a third through hole array 230 are provided on the pressure relief top plate 200. Wherein, the first through hole array 210, the second through hole array 220 and the third through hole array 230 are all provided with nylon plugs. When the high-temperature and high-pressure gas acts on the first pressure relief channel 101, it melts the nylon plug disposed on the first through hole array 210. When the high temperature, high pressure gas acts on the second pressure relief channel 102, it melts the nylon plug disposed on the second array of through holes 220. When the high-temperature and high-pressure gas acts on the third pressure relief passage 103, it melts the nylon plug disposed on the third through-hole array 230. Thus, the pressure relief top plate 200 is changed from the closed state to the open state, so that high-temperature and high-pressure gas can be discharged through the first through hole array 210, the second through hole array 220, and the third through hole array 230. The high-efficiency discharge of high-temperature and high-pressure gas is realized.

The utility model discloses a set up pressure release roof 200 at the top of the cabinet body, then utilize to set up first through-hole array 210, second through-hole array 220 and third through-hole array 230 on pressure release roof 200 to set up the nylon stopper respectively in first through-hole array 210, second through-hole array 220 and third through-hole array 230. The nylon stopper is melted by high-temperature and high-pressure gas, so that the discharge top plate is changed from a closed state to an open state. Thereby realizing the high-efficient discharge of high-temperature and high-pressure gas.

In some preferred embodiments, the switch cabinet with high-efficiency pressure relief protection further comprises a protection cover 300, the protection cover 300 is connected with the top of the cabinet body and covers the pressure relief top plate 200, and the protection cover 300 is provided with an air outlet array. Wherein, the gas outlet array can discharge high-temperature and high-pressure gas to the outside of the cabinet body. The protective cover 300 functions to limit the pressure relief top plate 200 to a certain range of the top of the cabinet through the hood. When the decompression top plate 200 is impacted by high-temperature and high-pressure gas, it may be lifted. When the pressure relief top plate 200 is lifted, it is restricted by the protective cover 300, so as to prevent the pressure relief top plate 200 from being lifted to other places to cause secondary damage.

In some preferred embodiments, the array of air outlet holes is a grid structure

In some preferred embodiments, the center line of the upper surface of the pressure relief top plate 200 is provided with a groove line 201. Because pressure release roof 200 bears certain pressure under the highly compressed gas effect of high temperature, in order to carry out better alleviating with this pressure, the event sets up groove line 201 through the upper surface median line position at pressure release roof 200 to make pressure release roof 200 when the atress, the whole atress of pressure release roof 200 is uneven, makes pressure release roof 200 use groove line 201 to wholly carry out deformation as the flex line. Through the mode of pressure release roof 200 deformation, absorb pressure, alleviate pressure.

In some preferred embodiments, the groove line 201 is a V-shaped groove line.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and changes without departing from the spirit of the invention.
