[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] The utility model provides a switch cabinet cover and a switch cabinet, please refer to Figure 1-4 , including a cabinet body 1, a pressure relief cover 3 is provided above a busbar chamber 2 of the cabinet body 1, and the pressure relief cover 3 is connected to the busbar chamber 2 through a plug-in structure.

[0032] A pressure relief hole 5 is provided on the pressure relief cover 3, and the pressure relief hole 5 is located in the middle of the pressure relief cover 3. The pressure relief hole 5 is used to relieve pressure, thereby reducing the extrusion force on the pressure relief cover 3 to a certain extent, thereby reducing the air pressure in the busbar chamber as much as possible, reducing the degree and probability of the cover plate being blown off, and making it more reliable to use; at the same time, the pressure relief hole can also dissipate heat for the busbar chamber, thereby avoiding excessive temperature inside the busbar chamber.

[0033] The plug-in structure comprises a first plug-in block 31 integrally provided on the pressure relief cover 3, and a rubber sleeve 311 is bonded to the outer wall of the plug-in block 31;

[0034] The plug-in structure also includes a first plug-in groove 11 opened on the cabinet 1, and the first plug-in block 31 and the rubber sleeve 311 are inserted into the first plug-in groove 11 together, and the size of the rubber sleeve 311 is larger than the first plug-in groove 11; the first plug-in block 31 can be directly inserted into the first plug-in groove 11; and when the rubber sleeve 311 is sleeved on the first plug-in block 31, when the first plug-in block 31 and the rubber sleeve 311 are inserted into the first plug-in groove 11 together, they need to be squeezed hard to squeeze in.

[0035] The cross-sections of the first plug-in block 31 , the rubber sleeve 311 and the first plug-in groove 11 are all isosceles trapezoidal, so that the rubber sleeve 311 and the first plug-in groove 11 form an “inverted hanging” structure, thereby ensuring the stability of the plug-in.

[0036] When in use, the first plug-in block 31 and the rubber sleeve 311 on the pressure relief cover 3 are squeezed into the first plug-in groove 11 by force; the rubber sleeve 311 and the first plug-in groove 11 form an "inverted hanging" structure, thereby ensuring the stability of the plug-in; and when the pressure relief cover 3 is subjected to a large extrusion force, the pressure relief cover 3 is easily separated from the busbar chamber, so that the pressure relief cover 3 will not fly up and cause danger;

[0037] By arranging a pressure relief hole on the cover plate, the busbar chamber can be depressurized, thereby reducing the air pressure in the busbar chamber as much as possible, reducing the degree and probability of the cover plate being blown off, and making it more reliable to use; at the same time, the pressure relief hole can also dissipate heat for the busbar chamber, thereby avoiding excessive temperature inside the busbar chamber and reducing the interference of excessive temperature on the use of components.

[0038] Embodiment 2:

[0039] Refer to the attached Figure 5-6 , which is different from the first embodiment in that: the plug-in structure includes a second plug-in block 32 and a rubber pad 4 integrally provided on the pressure relief cover 3, and the rubber pad 4 is bonded to the top of the busbar chamber 2;

[0040] The rubber pad 4 is provided with a second plug-in groove 41, and the second plug-in block 32 is inserted into the second plug-in groove 41. The size of the second plug-in block 32 is slightly larger than the second plug-in groove 41, so that the second plug-in block 32 is squeezed into the second plug-in groove 41;

[0041] The cross-sections of the second plug-in block 32 and the second plug-in groove 41 are both isosceles trapezoidal. Similarly, when the second plug-in block 32 is inserted into the second plug-in groove 41, a stable “inverted” structure is formed.

[0042] A placement groove 12 is opened at the top of the busbar chamber 2, and the rubber pad 4 is placed in the placement groove 12; at this time, the second plug-in block 32 is elastically clamped by the rubber pad 4, so as to ensure the stability and reliability of the installation of the pressure relief cover 3.

[0043] During specific use, the second plug-in block 32 of the pressure relief cover 3 is inserted into the second plug-in groove 41 to ensure the stability of the connection; when the busbar chamber fails and the pressure increases, the pressure relief cover 3 is easily separated from the busbar chamber, so that the pressure relief cover 3 will not fly off and cause danger.

[0044] By arranging a pressure relief hole on the cover plate, the busbar chamber can be depressurized, thereby reducing the air pressure in the busbar chamber as much as possible, reducing the degree and probability of the cover plate being blown off, and making it more reliable to use; at the same time, the pressure relief hole can also dissipate heat for the busbar chamber, thereby avoiding excessive temperature inside the busbar chamber and reducing the interference of excessive temperature on the use of components.

[0045] A switch cabinet has a switch cabinet cover plate on the top of its busbar chamber.
