Description

Technical Field

[0002] The secondary fusion mounted complete substation product is a substation that integrates many power equipment such as high-voltage and low-voltage switchgear and power transformers. It has been increasingly widely used in power systems due to its many advantages such as small footprint, low investment cost, high integration, and flexible solutions. In the secondary fusion mounted complete substation product, it has always been a difficult point in the manufacturing process to effectively dissipate the heat of the main power components such as the power equipment installed in it from the box of the secondary fusion mounted complete substation product to the outside.

[0039] Reference Figure 1-Figure 10 This embodiment also proposes a secondary fusion mounted complete substation, which is suitable for the above-mentioned ventilation and heat dissipation box.

[0040] Specifically, the working process or working principle of the ventilation and heat dissipation box is as follows: first, the first motor 204 is started, the first motor 204 can drive the double-groove pulley 207 to rotate, the rotation of the double-groove pulley 207 can drive the first pulley 206 to rotate, and the rotation of the first pulley 206 can drive the cooling fan 208 to rotate, so that the inside of the shell 1 can be heat-dissipated, and the temperature sensor 303 can control the telescopic length of the electric telescopic rod 304 according to the temperature. When the temperature sensor 303 detects that the temperature is within a threshold, the electric telescopic rod 304 can be started, so that the electric telescopic rod 304 stops after being extended to a certain length, and then when the temperature sensor 303 detects that the temperature is within a threshold, the electric telescopic rod 304 can be started, and the electric telescopic rod 304 stops after being extended to a certain length. When it is within another threshold, the electric telescopic rod 304 is started again to extend and retract the electric telescopic rod 304 to a certain length again. When the electric telescopic rod 304 is extended and retracted to a certain length, the second tooth plate 305 can be driven to move downward a certain distance, so that the second gear 306 can be rotated by a certain angle, and the rotation of the second gear 306 can drive the second rotating shaft 213 to rotate, so that the second pulley 215 can be rotated. At the same time, the rotation of the second pulley 215 can drive the third pulley 223 to rotate, and then drive the third rotating shaft 222 to rotate. The rotation of the third rotating shaft 222 can drive the rotating disk 218 to rotate, and then the size of the air inlet can be changed according to the temperature.

[0041] At the same time, the rotation of the second rotating shaft 213 can drive the first gear 214 to rotate, and the rotating first gear 214 can make the first tooth plate 211 move up and down. When the first tooth plate 211 moves up and down, it can drive the connecting plate 209 to move up and down inside the first sliding groove 210. When the connecting plate 209 moves up and down under the action of the first tooth plate 211, it can drive the mounting cylinder 307 to move up and down on the surface of the first rotating shaft 205, and the up and down movement of the mounting cylinder 307 can drive the first support seat 308 to move up and down, and the downward movement of the first support seat 308 can make the second rotating plate 312 The rotating second rotating plate 312 can rotate the first rotating plate 310 on the surface of the second support seat 309. When the first rotating shaft 205 rotates, it can drive the first support seat 308 and the second support seat 309 to rotate together, and then drive the knocking rod 311 to rotate centrifugally. When the temperature is getting higher and higher, the distance that the connecting plate 209 moves downward is longer, so that the inclination angle of the first rotating plate 310 is larger, and therefore the rotation diameter of the knocking rod 311 is also larger. When the temperature reaches the critical value, the knocking rod 311 can contact the copper plate 313 during rotation, so that the copper plate 313 sends out an alarm sound, thereby warning the staff.

[0042] When the staff needs to inspect the substation, in order to prevent the risk of electric shock, they can step on the top of the pedal 402 with both feet. Under the action of the staff's own weight, the pedal 402 can move downward. The downward moving pedal 402 can make the first threaded rod 405 move inside the first threaded cylinder 407, and then drive the first threaded cylinder 407 to rotate, and the rotation of the first threaded cylinder 407 can drive the third gear 406 to rotate. At the same time, the downward movement of the pedal 402 can compress the spring 404, so when the staff gets off the top of the pedal 402, the pedal 402 can be restored to its original position. When the third gear 406 rotates, the third tooth plate 408 can be driven to slide on the bottom of the inner cavity of the insulating platform 401, and the sliding of the third tooth plate 408 can drive the fourth gear 409 to rotate, and the rotation of the fourth gear 409 can drive the mounting column 410 to rotate, and then drive the inspection door 411 to rotate, so that the inspection door 411 can be automatically opened when the maintenance personnel stand on the pedal 402, avoiding the possibility of electric shock when the maintenance personnel pull the inspection door 411 by hand, and when the third tooth plate 408 moves, it can drive the second threaded rod 415 to slide inside the second fixing seat 414, so as to drive the maintenance personnel to open the inspection door 411 automatically. The rotation of the second threaded cylinder 413 can drive the fifth gear 416 to rotate, the rotating fifth gear 416 can drive the sixth gear 418 to rotate, and the rotating sixth gear 418 can drive the fourth rotating shaft 417 to rotate. When the fourth rotating shaft 417 rotates, the rotating fourth rotating shaft 417 can drive the fourth pulley 419 to rotate, and the fourth pulley 419 can drive the fifth pulley 422 to rotate under the action of the belt, and the rotation of the fifth pulley 422 can drive the third threaded rod 421 to rotate, and the rotation of the third threaded rod 421 can drive the cross plate 4 30 slides back and forth inside the first mounting groove 420. When the horizontal plate 430 moves inside the first mounting groove 420, it can drive the vertical plate 431 to move, and the movement of the vertical plate 431 can drive the connecting column 425 to move, so that the seventh gear 426 can move inside the straight groove plate 427. Under the action of the tooth groove 428, the seventh gear 426 can be rotated, and the rotation of the seventh gear 426 can drive the connecting column 425 to rotate. The rotation of the connecting column 425 can drive the fourth threaded rod 424 to rotate, and then the mounting plate 429 can be driven to slide up and down on the surface of the vertical plate 431.
