[0019] The technical scheme in the utility model embodiment will be clearly and completely described with reference to the drawings in the utility model embodiment.
[0020] Refer to Figures 1-5The dry-type transformer cabinet door safety protection installation structure includes a cabinet body 1, which houses the dry-type transformer. A cabinet door body 2 is rotatably mounted on the front of the cabinet body 1, and a handle 13 is fixedly connected to the front of the cabinet door body 2. A limit groove 8 is formed on the right inner wall of the cabinet body 1. The structure also includes a safety protection mechanism, comprising a rectangular inner cavity 3 within the cabinet body 1. A sliding block 4 is installed within the rectangular inner cavity 3, and the left side of the slider 4 is elastically connected to the left inner wall of the rectangular inner cavity 3 via two springs 5. A limit block 6 is fixedly connected to the right side of the slider 4, and the right end of the limit block 6 penetrates the right inner wall of the rectangular inner cavity 3 and slides against the inner wall of the limit groove 8. Two electromagnets are installed on the right inner wall of the rectangular inner cavity 3. 7. The right side of slider 4 is attached to the left side of the two electromagnets 7. Slider 4 cooperates with the two electromagnets 7. The right side of slider 4 is made of iron. By activating the power supply to the two electromagnets 7, the slider 4 and the two electromagnets 7 can be magnetically attracted, thereby ensuring the fixation of slider 4. A rectangular through groove 9 is opened between the front side of cabinet door body 2 and the front inner wall of rectangular cavity 3. A control block 10 is fixedly connected to the front side of slider 4. The front end of control block 10 passes through the rectangular through groove 9 and extends to the outside. A controller 11 is installed on the front side of cabinet door body 2. An alarm 12 is installed on the rear side of cabinet door body 2. The controller 11 is electrically connected to the two electromagnets 7 and the alarm 12. The power supply to the two electromagnets 7 can be controlled through the controller 11.
[0021] When the cabinet door body 2 needs to be opened, the operator can input a password through the controller 11 to stop the power supply to the two electromagnets 7, thereby releasing the magnetic attraction between the slider 4 and the two electromagnets 7. Then, pull the control block 10 to the left, causing the slider 4 and the limit block 6 to move to the left synchronously until the limit block 6 is completely disengaged from the limit groove 8. At this point, pulling the handle 13 forward will open the cabinet door body 2. When closing the door, pull the control block 10 to the left, causing the limit block 6 to move to the left, compressing the two springs 5. Then close the cabinet door body 2 and release the control block 10. Due to the elastic force of the two springs 5, the slider 4... The limit block 6 will automatically move to the right in sync. During this time, the right side of the slider 4 will be in contact with the two electromagnets 7, and the right end of the limit block 6 will be inserted into the limit groove 8. At this time, the operator can turn on the power supply to the two electromagnets 7 through the controller 11, so that the slider 4 and the two electromagnets 7 are magnetically attracted. This ensures that the slider 4 and the limit block 6 are fixed and prevents them from being pried open, thus ensuring the safe operation of the dry-type transformer in the cabinet 1. When the slider 4 and the two electromagnets 7 are forcibly separated due to external factors, the controller 11 can sense it and make the alarm 12 sound an alarm, thereby further improving the safety protection of the dry-type transformer in the cabinet 1.
[0022] When the cabinet door body 2 needs to be frequently switched in a short time, the power supply to the two electromagnets 7 can be stopped only, so that the cabinet door body 2 can be conveniently switched by moving the control block 10 to drive the limiting block 6 to move, thereby facilitating the maintenance and repair of the staff.
[0023] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
