In order to avoid the situation of electricity theft in the current transformer, an anti-electricity theft device for power transformer is provided.
[0003] At present, the theft of electricity occurs frequently, and the theft of electricity through the transformer is also rampant; the theft of electricity through the transformer is generally done by short-circuiting the secondary line of the transformer or connecting the secondary column head, causing serious losses.

[0022] Embodiment 1: By Figure 1-4It can be seen that the anti-electricity theft device for power transformer includes a first box body 1, a second box body 2 and a transformer 5. A controller 11 and a wireless transmitter 12 are installed on the inner side of the first box body 1. The models of the controller 11 and the wireless transmitter 12 are not limited. One side of the controller 11 is connected to a buzzer 10 fixed to the through hole of the first box body 1 through a wire. The controller 11 includes a processor and other structures, which are not specifically limited. The model of the buzzer 10 is not limited. A shift block 7 is fixed to the inner side of the second box body 2. An auxiliary mechanism is arranged inside the first box body 1. The auxiliary mechanism includes a shell 13, a round block 15, a switch 14, a slide rail 18, a sleeve 17, a connecting rod 16 and a spring 19. The back of the shell 13 The first housing 1 is fixedly connected to the inner side of the first housing 1. The inner side and one side through hole of the housing 13 are movably connected with a round block 15. The round block 15 can move in the inner side and one side through hole of the housing 13. A switch 14 is fixedly connected to one side through hole of the housing 13. The upper and lower sides of the housing 13 are fixedly connected with a slide rail 18. The outer side of the slide rail 18 is slidably clamped with a slide sleeve 17. The slide sleeve 17 can move on the outer side of the slide rail 18. The inner side of the slide sleeve 17 is fixedly connected to the outer side of the round block 15 through a connecting rod 16. The outer side of the slide rail 18 is slidably clamped with a spring 19. The device can drive the round block 15 to not contact the switch 14 by relying on the elastic deformation of the spring 19. The two ends of the spring 19 are respectively fixedly connected to one side of the slide rail 18 and one side of the slide sleeve 17.
[0023] In the specific implementation process, it is worth pointing out that through the cooperation between the sliding sleeve 17, the connecting rod 16 and the spring 19, the real-time monitoring of the lock being pried is realized, the buzzer 10 can remind the thief, and at the same time, the opening information is sent to the processing terminal through the wireless transmitter 12 for reminder, which improves the anti-theft effect and solves the problem that the existing anti-theft device cannot warn the thief after opening and remind the staff, and the anti-theft effect is general;
[0024] Furthermore, the back of the mutual inductor 5 is fixedly connected to the inner side of the second box 2, a wire 4 is arranged inside the mutual inductor 5, and corresponding locking noses 3 are installed on the outer sides of the first box 1 and the second box 2;
[0025] In the specific implementation process, it is worth pointing out that after the first box body 1 and the second box body 2 are fitted together, every two lock noses 3 fit together and can be locked and fixed with a lock head;
[0026] Furthermore, the outer wall of the wire 4 is movably connected with a rubber sleeve 6, the outer side of the rubber sleeve 6 is glued to the bottom through hole of the second box body 2, the inner side of the second box body 2 is fixed with an arc plate 23, and the two inner grooves of the arc plate 23 are both equipped with rubber protrusions 24 that are tightly pressed against the outer side of the wire 4;
[0027] In the specific implementation process, it is worth pointing out that the rubber sleeve 6 can seal the gap between the wire 4 and the second box 2, and can be pressed against the outside of the wire 4 by the elastic deformation of the rubber protrusion 24 to prevent the wire 4 from moving at will;
[0028] Specifically, when using the anti-electricity theft device for the power transformer, after the user buckles the first box body 1 and the second box body 2, the dial block 7 contacts the round block 15. It is worth noting here that one end of the dial block 7 is also designed to be arc-shaped. After the two are in contact, the round block 15 can be driven to contact the switch 14. If other people open it, the dial block 7 is separated from the round block 15, and the elastic deformation of the spring 19 can drive the round block 15 to stop contacting the switch 14. At this time, the switch 14 is no longer in contact and sends a signal to the controller 11. The controller 11 controls the buzzer 10 to start and emit a sound for warning, and sends the opening information to the processing terminal through the wireless transmitter 12 for reminder. When the staff uses it, the entire anti-theft system can be shut down through the terminal for repair and maintenance.
[0029] Embodiment 2: By Figure 1 , 2 As can be seen from Figures 4, a glass plate 9 is installed in the inner through hole of the first box body 1, and a metal shielding net 8 is installed on the inner side of the first box body 1;
[0030] In the specific implementation process, it is worth pointing out that the metal shielding net 8 can prevent the strong external magnetic field from affecting the work;
[0031] Furthermore, a shell 20 is fixed to the inner side of the second box body 2 by bolts, a mesh plate 21 is installed in a through hole on one side of the shell 20, and a dehumidifier bag 22 is arranged inside the shell 20;
[0032] In the specific implementation process, it is worth pointing out that the dehumidifier bag 22 can absorb the water vapor inside the second box 2 through the mesh plate 21 to prevent the humidity inside the box from being too high;
[0033] Specifically, based on the above-mentioned embodiment 1, the absorption of moisture inside the device is achieved through the cooperation between the second box body 2, the mesh plate 21 and the dehumidifier bag 22. If the humidity is too high, the insulating material of the current transformer will decompose and damage the insulation performance of the transformer, thereby affecting the service life of the current transformer.
