Description

Technical Field

[0001] The present invention relates to the technical field of switching devices, and particularly to a high isolation voltage intelligent switching switch.

Background Art

[0002] A disconnecting switch is a switching device mainly used for "isolating power sources, performing switching operations, and connecting and disconnecting current circuits" without an arc extinguishing function. When the disconnecting switch is in the open position, there is an insulating distance and an obvious disconnection between the contacts that meet the specified requirements; when in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. The main feature of the disconnecting switch is its lack of arc extinguishing ability and can only connect and disconnect the circuit without load current.

[0003] The currently used disconnecting switch, as Figure 9 shown, includes an insulating frame 1. In the frame 1, there are upper and lower copper bars arranged in parallel. The upper copper bar consists of an upper left copper bar 2 and an upper right copper bar 3, and the lower copper bar consists of a lower left copper bar 4 and a lower right copper bar 5. A movable rod 25 that can move up and down is provided at the center of the frame 1, and upper and lower connecting copper bars 14 and 15 arranged in parallel are provided on the movable rod 25. When the movable rod is pressed down, both sides of the upper connecting copper bar 14 are in contact with the upper left copper bar 2 and the upper right copper bar 3 respectively, realizing the conduction between the upper left copper bar 2 and the upper right copper bar 3, and both sides of the lower connecting copper bar 15 are in contact with the lower left copper bar 4 and the lower right copper bar 5 respectively, realizing the conduction between the lower left copper bar 4 and the lower right copper bar 5.

[0004] The disadvantages of the currently used disconnecting switch are as follows: 1. It lacks an intelligent and automated switching function. 2. Due to size and stroke limitation problems, there are certain risks in the safety distance of the ordinary structure under high-frequency and high-voltage conditions. 3. After the disconnecting switch is disconnected, if misoperation causes the movable rod to be pressed down, it may connect the already disconnected circuit, causing an electrical safety hazard.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A high isolation voltage intelligent switching switch includes an insulating frame body.

Detailed implementation manners

[0023] The following further describes in detail a high isolation voltage intelligent switching switch according to the present invention through specific embodiments.

[0024] Such as Figure 1 、 Figure 2As shown in the figure, a high isolation voltage intelligent switching switch includes an insulating frame body 1. In the frame body 1, an upper copper row and a lower copper row are arranged in parallel. The upper copper row is composed of an upper left copper row 2 and an upper right copper row 3, and the lower copper row is composed of a lower left copper row 4 and a lower right copper row 5. A hollow outer screw rod 6 is arranged at the center of the frame body 1, and an inner shaft 7 is passed through the outer screw rod 6 through a bearing. An outer servo motor 8 for driving the outer screw rod 6 to rotate and an inner servo motor 9 for driving the inner shaft 7 to rotate are arranged on the frame body 1. A passive gear 10 is arranged at the top of the inner shaft 7, and an active gear 11 is arranged on the output shaft of the inner servo motor 9. An intermediate gear 12 that meshes with each other is arranged between the active gear 11 and the passive gear 10. A slider 13 that is threadedly connected to the outer screw rod 6 is arranged on the outer screw rod 6. An upper connecting copper row 14 and a lower connecting copper row 15 that are parallel to each other are connected below the slider 13. An upper spring boosting assembly 16 is arranged between the slider 13 and the upper connecting copper row 14, and a lower spring boosting assembly 17 is arranged between the upper connecting copper row 14 and the lower connecting copper row 15. As Figure 6 shown, a convex pin 18 is arranged at the connection between the inner shaft 7 and the upper connecting copper row 14 and the lower connecting copper row 15, so as to realize the circumferential locking connection between the centers of the upper connecting copper row 14 and the lower connecting copper row 15 and the inner shaft 7. The structures of the upper connecting copper row 14 and the lower connecting copper row 15 are the same. As Figure 3 , Figure 4 shown, it includes an insulating circular shell 19 and a contact copper row 20 arranged in the shell 19. The two ends of the contact copper row 20 are fan-shaped structures. The contact copper row 20 separates two fan-shaped insulating surfaces 21 on both sides of the shell 19, and a partition 22 that is higher than the surface of the contact copper row 20 is arranged at the inner edge of the contact copper row 20. As Figure 5 shown, the contact end shapes of the upper left copper row 2, the upper right copper row 3, the lower left copper row 4, and the lower right copper row 5 are smaller than the fan-shaped structures at both ends of the contact copper row 20. A signal contact 23 for detecting the position of the slider 13 and a controller 24 for controlling the operation of the outer servo motor 8 and the inner servo motor 9 are arranged on the frame body 1.

[0025] The working principle of the present invention is as follows: When in use, if it is necessary to open the disconnecting switch, the controller 24 controls the external servo motor 8 to drive the external screw rod 6 to rotate in the reverse direction, so that the slider 13, the upper connecting copper bar 14 and the lower connecting copper bar 15 move upward. When the signal contact 23 detects the signal of the slider 13, the controller 24 stops the operation of the external servo motor 8. At this time, the upper connecting copper bar 14 is disconnected from the upper left copper bar 2 and the upper right copper bar 3, and the lower connecting copper bar 15 is disconnected from the lower left copper bar 4 and the lower right copper bar 5. Then the controller 24 controls the internal servo motor 9 to drive the inner shaft 7 to rotate 90 degrees, so that the upper connecting copper bar 14 and the lower connecting copper bar 15 rotate 90 degrees. At this time, the contact copper bar 20 is no longer located in the radiation surface of the upper copper bar and the lower copper bar, and the two fan-shaped insulating surfaces 21 are located directly above the upper copper bar and the lower copper bar. Then, the external servo motor 8 is driven to rotate the external screw rod 6 in the forward direction, so that the slider 13, the upper connecting copper bar 14 and the lower connecting copper bar 15 move downward, so that the upper copper bar and the lower copper bar are clamped into the two fan-shaped insulating surfaces 21 of the housing 19. Through the action of the partition 22, complete and safe electrical isolation is achieved. At this time, the structure is as shown in Figure 7 shown. If it is necessary to close the disconnecting switch, only the reverse operation is required. The controller 24 controls the external servo motor 8 to drive the external screw rod 6 to rotate in the reverse direction, so that the slider 13, the upper connecting copper bar 14 and the lower connecting copper bar 15 move upward. When the signal contact 23 detects the signal of the slider 13, the controller 24 stops the operation of the external servo motor 8. Then the controller 24 controls the internal servo motor 9 to drive the inner shaft 7 to rotate 90 degrees, so that the upper connecting copper bar 14 and the lower connecting copper bar 15 rotate 90 degrees. At this time, the contact copper bar 20 is located directly above the upper copper bar and the lower copper bar. Then, the external servo motor 8 is driven to rotate the external screw rod 6 in the forward direction, so that the slider 13, the upper connecting copper bar 14 and the lower connecting copper bar 15 move downward, so that the contact copper bar 20 contacts the upper copper bar and the lower copper bar respectively, and is pressed through the upper spring pressurizing assembly 16 and the lower spring pressurizing assembly 17, respectively realizing the conduction of the upper copper bar and the lower copper bar. At this time, the structure is as shown in Figure 8 shown.

[0026] The above embodiments only illustratively explain the principles and effects of the present invention and some applied embodiments, rather than limiting the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
