[0003] Generally, high-voltage switch cabinets are arranged closely side by side in the power distribution room, but this arrangement is not conducive to heat dissipation. In addition, high-voltage switches use aluminum-zinc plates as the cabinet body, and paint is sprayed on the front and back sides of the cabinet body. Spraying paint will affect the heat dissipation performance. Only the aluminum-zinc plates on both sides have good heat dissipation. At present, most vacuum circuit breakers are equipped with cross-flow fans at 4000A for forced heat dissipation, and the method of increasing the ventilation area on the front and back doors of the cabinet is inappropriate because people will pass by the front and back doors, and when arcing occurs, the possibility of injury to personnel increases.

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-Figure 7As shown, the utility model provides a heat dissipation type high-voltage switch cabinet with a detachable dust blocking structure, including a switch cabinet body 1, and air intake axial flow fans 3 for air intake are arranged on the left and right sides of the switch cabinet body 1, and the air intake axial flow fans 3 are used to introduce external air into the switch cabinet body 1 for heat dissipation. By increasing the air flow inside the switch cabinet body 1, the temperature of electrical equipment and components can be reduced. An air outlet assembly 6 for air outlet is arranged at the top of the switch cabinet body 1, and the air outlet assembly 6 includes a mounting seat 63 arranged at the top of the switch cabinet body 1, and the mounting seat has an impeller inside, and the impeller can rotate around its axis. A rotating drive member 62 is fixed to the outside of the mounting seat 63, and the output end of the rotating drive member 62 is connected to the impeller 61. The front and rear sides of the switch cabinet body 1 are also provided with an observation window 11 for convenient observation and inside. When the rotating drive member 62 is started, the rotating drive member 62 drives the impeller 61 to rotate. The rotation of the impeller 61 generates wind force to blow out the hot air inside the switch cabinet body 1.

[0028] By opening shutter-type air inlet holes 12 at the bottom of the left and right sides of the switch cabinet body 1, and adding multiple air inlet axial flow fans 3 on the left and right sides for forced convection, the air inlet speed is increased, so that the heat dissipation effect of the switch cabinet body 1 is better. Compared with the existing method of increasing the ventilation area on the front and rear doors, this method is safer.

[0029] At least two air outlet components 6 are installed at the top of the switch cabinet body 1, and at least three air inlet axial flow fans 3 are installed on each side of the switch cabinet body 1. Several air inlet holes 12 for air intake are opened near the bottom of the front and rear sides and the bottom of the left and right sides of the switch cabinet body 1. A filter 4 for preventing dust from entering the switch cabinet body 1 is detachably installed near the air inlet hole 12 on the switch cabinet body 1. A quick-release component 7 for conveniently removing the filter 4 is also installed on the switch cabinet body 1.

[0030] An air outlet 2 is disposed on the top of the switch cabinet body 1 , and a plurality of air outlet holes 21 are formed around the air outlet 2 .

[0031] Fresh air enters from both sides through the air inlet axial flow fans 3, passes through the circuit breaker room, cable room and busbar room in the switch cabinet body 1, and is discharged from the top of the cabinet. Compared with the traditional heat dissipation method, this heat dissipation method has a better effect.

[0032] A plurality of grooves 41 are formed around the filter 4, and the quick-release assembly 7 corresponds to the grooves 41 one by one. The quick-release assembly 7 includes a hinge block 71 fixed to the switch cabinet body 1, a threaded rod 72 is rotatably provided on the hinge block 71, the threaded rod 72 can be stuck in the groove 41, and a rotating sleeve 73 for pressing the filter 4 on the switch cabinet body 1 is screwed on the threaded rod 72.

[0033] The filter screen 4 can be sleeved on one of the air inlet axial flow fans 3. The outer sleeves of two of the air inlet axial flow fans 3 are provided with filter covers 5, and the contact surfaces of the filter covers 5 and the switch cabinet body 1 are provided with magnets, so that the filter covers 5 can be adsorbed on the switch cabinet body 1.

[0034] By rotating the rotating sleeve 73 to loosen the threaded rod 72, the rotating sleeve 73 is then released from the groove 41, so that the filter screen 4 can be easily removed. The filter cover 5 is magnetically adsorbed on the switch cabinet body 1, so that the filter cover 5 can be easily removed, and the filter screen 4 and the filter cover 5 can be removed for cleaning.

[0035] Working principle: When in use, by starting the rotating driving member 62, the rotating driving member 62 rotates the impeller 61, so that the air inside the switch cabinet body 1 flows, by opening a shutter-type air inlet hole 12 at the bottom of the left and right sides of the switch cabinet body 1, and adding multiple air inlet axial flow fans 3 on the left and right sides to perform forced convection and increase the air inlet speed, an air outlet 2 is provided on the top of the switch cabinet body 1, and a plurality of air outlet holes 21 are provided around the air outlet 2, and fresh air enters from both sides through the air inlet axial flow fans 3 , respectively passing through the circuit breaker room, cable room, and busbar room in the switch cabinet body 1, and then discharged from the cabinet top, so that the heat dissipation effect of the switch cabinet body 1 is better. When too much dust accumulates on the filter 4 and the filter cover 5, the threaded rod 72 is loosened by rotating the rotating sleeve 73, and then the rotating sleeve 73 is disengaged from the groove 41, so that the filter 4 can be easily removed, and the filter cover 5 is adsorbed on the switch cabinet body 1 by magnetic attraction, so the filter cover 5 can be easily removed, and the filter 4 and the filter cover 5 can be removed for cleaning.
