Description

Technical Field

[0002] The magnetically controlled pole switch is a new type of pole switch introduced in recent years. It uses a magnetically controlled mechanism with a semi-hard magnetic material as the core to replace the traditional permanent magnetic mechanism. It has the characteristics of small size, low driving power, long service life, and excellent closing and opening time characteristics. It is expected to replace the permanent magnetic mechanism pole switch and the spring-operated mechanism pole switch and become a new generation of pole switch in the field of distribution network automation. At present, the opening and closing indicator structure of the magnetically controlled pole switch mainly follows the opening and closing indicator structure of the permanent magnetic mechanism pole switch and the spring-operated mechanism pole switch, which cannot meet the needs of the development of new magnetically controlled pole switch technology.

[0003] The existing technology generally includes a pointer shaft and a transmission rod of the opening and closing indicator. The movement of the transmission rod drives the pointer shaft of the opening and closing indicator to rotate, thereby completing the indication of the opening and closing indicator. The connection between the pointer shaft of the opening and closing indicator and the transmission rod is a mechanical connection.

[0004] Regarding the above-mentioned related technologies, when a mechanical connection fails (such as getting stuck), the movement of the moving iron core that drives the transmission rod will be affected, thereby affecting the normal opening and closing of the switch on the magnetic control column.

[0008] By adopting the above technical solution, when the magnetic control column switch is opened or closed, the moving iron core moves toward or away from the magnetic control body, the moving iron core drives the transmission rod to move toward or away from the magnetic control body, the movement of the transmission rod drives the first transmission magnet to move toward or away from the magnetic control body, the movement of the first transmission magnet drives the transmission block to move toward or away from the magnetic control body through magnetic attraction, the transmission block drives the transmission disk to rotate, the rotation of the transmission disk drives the transmission shaft to rotate, the rotation of the transmission shaft drives the pointer to rotate, thereby completing the indication of the opening and closing indicator, improving the problem that when the mechanical connection fails (such as getting stuck), the movement of the moving iron core that drives the transmission rod will be affected, thereby affecting the normal opening and closing of the switch on the magnetic control column.

[0009] Optionally, the transmission disc is provided with a sliding groove, and the transmission block is passed through and slidingly engaged in the sliding groove.

[0010] By adopting the above technical solution and setting the sliding groove, when the first transmission magnet moves to drive the transmission block to move, the transmission block slides along the sliding groove, so that the first transmission magnet and the transmission block always remain coaxial during the movement, thereby making the magnetic attraction cooperation between the first transmission magnet and the transmission block more stable, thereby making the magnetic attraction effect between the first transmission magnet and the transmission block better and making it easier to use.

[0011] Optionally, the switching operations of the magnetic control components of each group do not interfere with each other, and each group of the magnetic control components corresponds to each of the transmission components.

[0012] By adopting the above technical solution, each group of magnetic control components and each transmission component corresponds to each other, so that when each group of magnetic control components is opened and closed, each group drives each pointer to indicate separately, thereby displaying the opening and closing status of the switch between different magnetic control components, so that the switch opening and closing indicator simultaneously indicates the three-phase opening and closing status of the switch on the magnetic control column, making it more usable.

[0016] By adopting the above technical solution, when the pointer indicates opening or closing of the switch, the limit ring is fixed tightly against the transmission shaft, so that the transmission shaft is not easy to continue to rotate, thereby making it difficult for the pointer to over-indicate. At the same time, the limit ring is fixed tightly against the transmission shaft, so that the position of the pointer is stable and not easy to shake when indicating, thereby making the indication effect of the pointer better and making it more usable.

[0017] Optionally, the limiting sleeve further includes a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion are fixedly connected, and the thread directions of the first limiting portion and the second limiting portion are opposite.

[0018] By adopting the above technical solution, the thread directions of the first limiting part and the second limiting part are opposite, so that when the limiting sleeve rotates in the clockwise direction or the counterclockwise direction, the limiting sleeve and the limiting ring are both threadedly connected, so that the two threaded connection states of the limiting sleeve and the limiting ring are more corresponding to the two indication states of the pointer, so that the limiting ring can be better threadedly connected to the limiting sleeve according to the indication state of the pointer, making it more usable.

[0019] Optionally, the indicating mechanism also includes multiple groups of driving components, each group of driving components drives each limiting component respectively, each driving component includes a driving sun gear, a driving ring gear and a driving planetary gear, the driving sun gear is coaxially fixed on the transmission shaft, the driving ring gear is fixed on the base, the driving planetary gear is arranged between the driving sun gear and the driving ring gear, the driving planetary gear is rotatably arranged on the limiting sleeve, one side of the driving planetary gear is meshed with the driving sun gear, and the other end of the driving planetary gear is meshed with the driving ring gear.

[0020] By adopting the above technical solution, when the transmission shaft rotates, the transmission shaft drives the driving sun gear to rotate, thereby causing the driving planetary gears to rotate around their own axes and circumferentially around the axis of the driving sun gear, driving each planetary gear to rotate and driving the limit sleeve to rotate, so that the speed of the driving limit sleeve is transmitted from the driving planetary gear, thereby making the rotation speed of the limit sleeve faster, so that when the transmission shaft rotates to the set position, the limit ring is tightly pressed against the transmission shaft, so that the limiting effect of the limit ring on the transmission shaft is better, making it more usable.

[0021] Optionally, the limiting assembly further includes a rubber block, and the rubber block is fixedly disposed on the limiting ring. When the limiting ring is tightly fixed to the transmission shaft, the rubber block is tightly fixed to the transmission shaft.

[0022] By adopting the above technical solution and the provision of the rubber block, the tight fixation stability between the limit ring and the transmission shaft is improved, thereby improving the usability.

[0024] 1. When the magnetic column switch is opened or closed, the moving iron core moves toward or away from the magnetic control body, and the moving iron core drives the transmission rod to move toward or away from the magnetic control body. The movement of the transmission rod drives the first transmission magnet to move toward or away from the magnetic control body.

The transmission block drives the transmission disk to rotate, the rotation of the transmission disk drives the transmission shaft to rotate, and the rotation of the transmission shaft drives the pointer to rotate, thereby completing the indication of the opening and closing indicator.

[0025] 2. The setting of the sliding groove makes it possible for the transmission block to slide along the sliding groove when the first transmission magnet moves to drive the transmission block to move, so that the first transmission magnet and the transmission block always remain coaxial during the movement, thereby making the magnetic attraction between the first transmission magnet and the transmission block more stable, thereby making the magnetic attraction effect between the first transmission magnet and the transmission block better and making it easier to use.

[0026] 3. Each group of magnetic control components corresponds to each transmission component, so that when each group of magnetic control components is switched on and off, each group drives each pointer to indicate separately, thereby displaying the switch on and off status between different magnetic control components, so that the switch on and off indicator simultaneously indicates the three-phase switch on and off status of the switch on the magnetic control column, making it more usable.

The second transmission magnet 318 is fixedly arranged on the transmission block 317. The second transmission magnet 318 and the first transmission magnet 313 are magnetically matched.

[0041] When the first transmission magnet 313 moves toward or away from the magnetron 212, the first transmission magnet 313 drives the second transmission magnet 318 to slide along the sliding groove and rotate circumferentially around the axis of the transmission shaft 314, thereby driving the transmission disk 316 to rotate, and the rotation of the transmission disk 316 drives the transmission shaft 314 to rotate.

[0043] When the transmission shaft 314 rotates, the transmission shaft 314 drives the driving sun gear 332 to rotate, so that the driving planetary gears 334 rotate around their own axes and circumferentially around the axis of the driving sun gear 332, driving each driving planetary gear 334 to rotate and drive the limiting sleeve 321 to rotate, so that the speed of driving the limiting sleeve 321 is transmitted from the driving planetary gears 334, so that the rotation speed of the limiting sleeve 321 is faster, so that when the transmission shaft 314 rotates to the set position, the limiting ring 323 is tightly pressed against the transmission shaft 314, so that the limiting effect of the limiting ring 323 on the transmission shaft 314 is better.

[0044] The implementation principle of the magnetic transmission structure of the switch opening and closing indicator on the magnetron column in the embodiment of the present application is as follows: when the magnetron column switch is opened and closed, the moving iron core 213 moves toward or away from the magnetron body 212, and the moving iron core 213 drives the transmission rod 312 to move toward or away from the magnetron body 212. The movement of the transmission rod 312 drives the first transmission magnet 313 to move toward or away from the magnetron body 212. The movement of the first transmission magnet 313 drives the transmission block 317 to move toward or away from the magnetron body 212 through magnetic attraction. The transmission block 317 drives the transmission disk 316 to rotate, and the rotation of the transmission disk 316 drives the transmission shaft 314 to rotate. The rotation of the transmission shaft 314 drives the pointer 315 to rotate, thereby completing the indication of the opening and closing indicator, improving the problem that when the mechanical connection fails (such as getting stuck), the movement of the moving iron core 213 that drives the transmission rod 312 to move will be affected, thereby affecting the normal opening and closing of the switch on the magnetron column.
