Embodiment 1

[0039] Example 1, such as Figure 5 As shown, the incomplete gear 21 can be driven to rotate through the motor 19, and then the turntable 22 can be driven to rotate through the incomplete gear 21. When the incomplete gear 21 rotates to mesh with the gear A20, it can drive the gear A20 to rotate to one side. After the complete gear 21 is rotated to disengage from the mesh with the gear A20, the tooth block 23 can mesh with the gear A20, and the gear A20 is turned to the other side. When the tooth block 23 is disengaged from the mesh with the gear A20, the incomplete gear 21 can be Engage with the gear A20 again, and then the gear A20 drives the rotating plate 18 to swing repeatedly, so that the top of the mounting plate 10 can be blown by the fan 9 in a swinging manner, and the leaves and other sundries can be blown off.

Embodiment 2

[0040] Example 2, such as Figure 6-7 As shown, after putting multiple groups of moisture-absorbing bags into the discharge chute 7, when pushing the discharge chute 7 to close it, the discharge chute 7 can drive the chute 27 to slide along the slider 26, and the discharge chute 7 guide, while the discharge chute 7 can also drive the rack 30 to move. When the rack 30 meshes with the gear B25, the rack 30 can drive the gear B25 to rotate, and then the gear B25 can drive the rotating rod 29 to rotate to make the coil spring 28 is elastically crimped. After pushing the discharge chute 7 into the moisture absorption trough 24, the door is fixed by buckles to close the door. After closing, the moisture absorption bag can continuously absorb the moisture inside the transformer to prevent moisture from penetrating into the transformer. If the wire is short-circuited, when the dehumidification bag needs to be replaced, the fixing of the buckle is released, and the resilience force of ...

Abstract

The invention discloses a high-sealing oil-immersed transformer wiring top plate used in the high-low voltage electrical field, which comprises a wiring top plate main body. The top of the wiring top plate main body is provided with a mounting plate, the middle positions of the two ends of the mounting plate are provided with fixing plates, and the tops of the sides, close to each other, of the two fixing plates are sleeved with blowing assemblies; a clamping groove is formed in the outer side of the bottom of the wiring top plate body, an air bag B is arranged at the top of the inner side of the clamping groove, and air bags A are arranged at the bottoms of the two sides of the inner side of the clamping groove; through mutual cooperation of a fan, a mounting plate, a rotating plate, a motor, a gear A, an incomplete gear, a rotating disc and a tooth block, after the device is mounted, leaves and garbage can be guided through the design of a triangular slope at the top of the mounting plate, the probability that the garbage leaves fall on the mounting plate is reduced, and when the device is used, the fan can be controlled to blow air in a swinging mode. The inclined surface at the top of the mounting plate is used for guiding flow to blow off the garbage.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a high-tightness oil-immersed transformer wiring top plate used in the high-voltage and low-voltage electrical field. Background technique [0002] Oil-immersed transformer is a new type of high-performance transformer with more reasonable structure and better performance. The three-dimensional wound iron core has three-dimensional arrangement of equilateral triangles, so there is no air gap in the magnetic circuit, and the winding is more compact. The two magnetic circuits have the same length and are the shortest. The cross-sectional area of ​​the iron core is closer to a circle, so the performance is further improved, the loss is reduced, the noise is reduced, the three items are balanced, and the third harmonic component is reduced. This product is more suitable for It is more suitable for combined transformers and prefabricated transformers for substations in urban and ...
