Description

Technical Field

[0001] The utility model relates to the technical field of on-load tap-changers, in particular to an arc plate of an on-load tap-changer facilitating wire routing. Background Technique

[0002] In the power system, an on-load tap-changer is an important device used to adjust the output voltage of a transformer without interrupting the load current. This switch usually contains complex electrical and mechanical structures to ensure the stability and continuity of the current during the switching process. However, there may be some inconveniences in wiring for traditional on-load tap-changers, such as the problem that wire harnesses are prone to entanglement and insecure fixation, which may affect the operation efficiency and maintenance convenience of the equipment.

[0003] With the continuous development of power technology and the increasing expansion of the power grid scale, the performance requirements for on-load tap-changers are also getting higher and higher. On the arc plate of the on-load tap-changer, it is necessary to reasonably arrange multiple electrical wire harnesses to ensure the stability and safety of electrical connections. The traditional arc plate design often has the drawback of inconvenient wire harness management. Due to the lack of a scientific wire harness layout scheme and effective fixing devices, the arrangement of wire harnesses on the arc plate often appears chaotic, prone to crossing and entanglement. This not only increases the complexity of electrical connections and the difficulty of maintenance, but also may have an adverse impact on the normal operation of the switch.

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] As Figures 1-4 shown, the present application provides a on-load tap-changer arc plate facilitating wire routing, including a on-load tap-changer arc cylinder 1; a longitudinal adjustment groove 2 installed on the on-load tap-changer arc cylinder 1; a fixing mechanism 4 installed on the on-load tap-changer arc cylinder 1 for fixing the wire harness; the fixing mechanism 4 includes a connecting ring 401 installed on the on-load tap-changer arc cylinder 1, and an outer expansion part 402 is installed on the connecting ring 401; a lifting mechanism 3 installed on the on-load tap-changer arc cylinder 1 for driving the fixing mechanism 4 to move; the lifting mechanism 3 includes a slide rail 301 fixedly installed on the on-load tap-changer arc cylinder 1, and a sliding sleeve 303 is slidably connected to the slide rail 301; a heat dissipation mechanism 5 installed on the outer expansion part 402 for dissipating heat from the wire harness; the heat dissipation mechanism 5 includes a heat dissipation groove 501 installed on the outer expansion part 402.

[0025] In this embodiment: Since the lifting mechanism 3 is installed on the arc-shaped cylinder body 1 of the on-load tap-changer, by controlling the lifting mechanism 3, the connecting ring 401 can be driven to move up and down, so that the device can accommodate more wire harnesses, which is convenient for limiting the wire harnesses in different working environments. Since the fixing mechanism 4 is installed on the arc-shaped cylinder body 1 of the on-load tap-changer, by controlling the fixing mechanism 4, the device can better limit and fix the wire harnesses, and by controlling the heat dissipation mechanism 5, heat dissipation can be carried out when the wire harnesses are working.

[0026] Specifically, as Figure 2 shown, the fixing mechanism 4 includes a telescopic rod 404 installed on the connecting ring 401. The telescopic rod 404 is slidably connected to the outward expanding member 402. The outward expanding member 402 is fixedly connected to the connecting ring 401. A fixing spring 408 is fixedly connected to the outward expanding member 402, and a fixing plate 409 is fixedly connected to the fixing spring 408. A connecting circular plate 405 is fixedly connected to the arc-shaped cylinder body 1 of the on-load tap-changer; a connecting spring 403 is fixedly connected to the connecting ring 401, and the outward expanding member 402 is fixedly connected to the connecting spring 403. The outward expanding member 402 is fixedly connected to the connecting ring 401 through the connecting spring 403; a first limiting groove 406 is fixedly connected to the connecting circular plate 405, and a second limiting groove 407 is fixedly connected to the connecting circular plate 405.

[0027] In this embodiment: Since the fixing mechanism 4 includes a connecting ring 401 slidably connected to the arc-shaped cylinder body 1 of the on-load tap-changer, a connecting spring 403 is installed on the connecting ring 401, and the connecting spring 403 is fixedly connected to the outward expanding member 402. And a telescopic rod 404 is installed on the connecting ring 401, and the telescopic rod 404 is slidably connected to the outward expanding member 402. Through the cooperation of the telescopic rod 404 and the connecting spring 403, the outward expanding member 402 can fix more wire harnesses, and through the cooperation of the fixing spring 408 and the fixing plate 409, the wire harnesses can be fixed. Since the first limiting groove 406 and the second limiting groove 407 are provided on the connecting circular plate 405, the device can limit multiple groups of wire harnesses.

[0028] Specifically, as Figure 1 shown, the lifting mechanism 3 includes a limiting hole 302 fixedly installed on the slide rail 301. A sliding sleeve 303 is slidably connected to the slide rail 301. The sliding sleeve 303 is provided with a limiting rod 304, and the limiting rod 304 is in contact with the limiting hole 302. The sliding sleeve 303 is fixedly connected to the connecting ring 401. [[ID=]14]

[0029] In this embodiment: Since the lifting mechanism 3 includes a slide rail 301 fixedly installed on the arc-shaped cylinder body 1 of the on-load tap-changer, a limiting hole 302 is formed in the slide rail 301, a sliding sleeve 303 is slidably connected to the slide rail 301, a limiting rod 304 is installed on the sliding sleeve 303, the limiting hole 302 contacts the limiting rod 304, and the sliding sleeve 303 is fixedly connected to the connecting ring 401. By adjusting the sliding of the sliding sleeve 303 on the slide rail 301, the positions of the connecting ring 401 and the outward expansion member 402 can be adjusted, so that the device can accommodate more wire harnesses.

[0030] Specifically, as Figure 3 shown, the heat dissipation mechanism 5 includes heat dissipation grooves 501 on the outward expansion member 402, first heat dissipation holes 502 are formed in the heat dissipation grooves 501, and second heat dissipation holes 503 are formed in the connecting circular plate 405.

[0031] In this embodiment: Since the heat dissipation mechanism 5 includes heat dissipation grooves 501 installed on the outward expansion member 402, first heat dissipation holes 502 are formed in the heat dissipation grooves 501, and second heat dissipation holes 503 are formed in the connecting circular plate 405. When the wire harness starts to work, through the heat dissipation grooves 501, the first heat dissipation holes 502 and the second heat dissipation holes 503, the heat dissipated by the wire harness can be dissipated more quickly, so that the wire harness can work more stably.

[0032] The specific solution of this scheme is as follows: The staff can fix according to the size of the wire harness through the fixing mechanism 4, and through the lifting mechanism 3, the change in the height of the device can be adjusted, so that the wire harness can be fixed better. And through the heat dissipation mechanism 5, better heat dissipation can be carried out when the wire harness is working, so that the wire harness can work more stably.
