The arrangement of the first mounting hole 7 facilitates the connection and installation of the entire device with other components of the power system. A driving component 5 is arranged inside the mobile bin at the bottom of the wire seat 4. The driving component 5 is composed of a moving plate 51, a connecting rod 52, a pin 53, a slide groove 54, a slider 55, a contact knife 56 and a contact 57. The moving plate 51 is arranged between the wire seats 4, and the front and rear sides of the moving plate 51 are symmetrically arranged with connecting rods 52. The upper and lower ends of the connecting rod 52 are rotatably installed with pins 53. The top of the connecting rod 52 is rotatably connected to the moving plate 51 through the pins 53. The pins 53 at the bottom of the connecting rod 52 pass through the slide grooves 54 arranged in the middle of the front and rear sides of the wire seat 4 and are slidably installed on the wire seat 4. The slider 55 in the moving bin is fixedly connected, and a contact knife 56 is fixedly installed at the center of the opposite end of the slider 55, and a contact head 57 matching the plug-in connection is arranged at the other end of the contact knife 56. A driving component 2 6 for driving the moving plate 51 to move up and down is arranged in the middle of the connecting channel steel 1. When the moving plate 51 moves upward, the pin shaft 53 at the top of the connecting rod 52 is connected to the moving plate 51, so that the pin shaft 53 at the bottom of the connecting rod 52 passes through the slide groove 54 to drive the slider 55 to move toward the moving plate 51 along the moving bin at the bottom of the line seat 4 at the same time. As the slider 55 continues to move toward the middle, the contact head 57 at the end of the contact knife 56 gradually approaches and is finally plug-in connected, thereby realizing the closing of the isolating switch, and vice versa, realizing the opening of the isolating switch. 6 is composed of an electric telescopic rod 61, a connecting plate 62 and a guide rod 63. Two electric telescopic rods 61 are provided. The electric telescopic rods 61 are fixedly installed at the middle part of the connecting channel steel 1 symmetrically on the left and right. The telescopic end of the electric telescopic rod 61 is fixedly installed with a connecting plate 62. The bottom center of the connecting plate 62 is fixedly connected to a guide rod 63 slidably installed in a sliding hole in the middle part of the connecting channel steel 1. The bottom of the guide rod 63 is fixedly connected to the top center of the moving plate 51. The input end of the electric telescopic rod 61 is electrically connected to the output end of the external controller. The connecting plate 62 is driven to move up and down through the telescopic end of the electric telescopic rod 61, so that the guide rod 63 can drive the moving plate 51 to move up and down. It also includes a reset spring 8, which is arranged at the top center of the moving plate 51.The reset spring 8 is set on the outside of the guide rod 63, and the upper and lower ends of the reset spring 8 are respectively fixedly connected to the top of the moving plate 51 and the bottom of the connecting channel steel 1. The reset spring 8 can be compressed to store energy when closing the switch, and can release energy to help the driving component 1 5 to reset when opening the switch.
[0018] The working principle of the utility model is as follows: when the switch needs to be closed, the user can send a start signal to the electric telescopic rod 61 through an external controller. After the electric telescopic rod 61 receives the signal, its telescopic end begins to extend, so that the connecting plate 62 drives the guide rod 63 to move upward. Since the guide rod 63 is connected to the movable plate 51, as the guide rod 63 moves upward, the movable plate 51 fixedly connected thereto also moves upward. When the movable plate 51 moves upward, the pin shaft 53 at the top of the connecting rod 52 is connected to the movable plate 51, so that the pin shaft 53 at the bottom of the connecting rod 52 passes through the slide groove 54 and drives the slider 55 to move toward the movable plate 51 along the movable bin at the bottom of the line seat 4 at the same time. As the slider 55 continues to move toward the middle, the touch knife 56 at the end of the touch knife 56 is touched. The heads 57 gradually approach and finally plug into the connection, thereby closing the isolating switch. During the closing process, the reset spring 8 is squeezed by the moving plate 51, thereby preparing for the reset during the opening operation. When opening is required, a retraction signal is sent to the electric telescopic rod 61 through an external controller. As the telescopic end of the electric telescopic rod 61 retracts, the guide rod 63 drives the moving plate 51 to move downward. Due to the connection between the pin shaft 53 and the connecting rod 52, the slider 55 is driven to move outward in the moving bin at the bottom of the wire seat 4, so that the contact 57 at the end of the contact knife 56 is separated, thereby opening the isolating switch. During the opening process, the reset spring 8 gradually releases the previously stored energy to help the drive component 5 to reset to the initial position.
