As the core component for voltage step-up and step-down, the performance of the transformer directly affects the stable operation and energy efficiency of the power system. However, existing devices have certain drawbacks. For example, the transformer measuring device for distribution cabinets described in announcement number CN221148828U relates to the field of transformer measuring technology for distribution cabinets. It includes a housing, a control panel and control keys on the cover, a detection component set inside the housing, a wiring assembly consisting of a guide column, helical gear B and a connecting rod, and a rotation drive structure consisting of a driver, a guide shaft and helical gear A.

[0003] The above-mentioned device can improve wiring efficiency by using a drive structure to retract the wire. However, the user needs to hold the device when using it. The device cannot be fixed to the distribution cabinet during testing, which means that the user can only operate it with one hand, affecting the user experience when testing transformers.

[0012] Furthermore, the outer surface of the limiting seat is provided with a limiting hole, the insertion post passes through the limiting hole, and the outer surface of the clamp is fixedly connected with a second anti-slip pad.

[0013] Furthermore, one end of the junction box is embedded with a blocking cover, the inner surface of the blocking cover is fixedly connected with a locking protrusion, and the outer surface of the locking protrusion is fixedly connected with a locking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Under the elastic force of the first spring, the snap-fit ​​plate and snap-fit ​​block located in the slide groove contact each other to limit the cover. The other end of the snap-fit ​​plate contacts the snap-fit ​​block to limit the blocking cover.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a transformer measuring device for a distribution cabinet includes a housing 1, a detection component 3 is fixedly connected inside the housing 1, a spiral detection line 301 is fixedly connected to the lower surface of the detection component 3, a cover 2 is hinged to the outer surface of the housing 1, and a wire box 4 is fixedly connected to the rear surface of the housing 1.

[0024] A clamping mechanism 5 is provided on the rear surface of the housing 1. The clamping mechanism 5 includes a limiting rail 501, a limiting seat 502, a clamping plate 504, and an insertion post 507. The limiting rail 501 is fixedly connected to the rear surface of the housing 1, the limiting seat 502 is fixedly connected to the outer surface of the limiting rail 501, the clamping plate 504 is slidably connected to the outer surface of the limiting rail 501, and the insertion post 507 is fixedly connected to the outer surface of the clamping plate 504. A second spring 505 is nested on the outer surface of the insertion post 507.

[0025] Specifically, the detection component 3 is an IM1253B single-phase AC / DC electrical measurement module, used to accurately measure various parameters of the transformer. In use, the detection line 301 is electrically connected to the location to be tested. This is existing technology and will not be elaborated further. The mounting foot 401, in conjunction with the threaded assembly, mounts the junction box 4 to the back of the housing 1. The mounting shaft 402 limits the movement of the first spring 403. Under the elastic force of the first spring 403, the snap-fit ​​plate 404 and snap-fit ​​block 203 located in the slide groove 102 contact each other, limiting the cover 2. The other end of the snap-fit ​​plate 404 contacts the snap-fit ​​block 602, facilitating the limiting of the blocking cover 6. The blocking cover 6, in conjunction with the junction box 4, limits the movement of the spiral detection line 301. 1. The device is stored away for easy access to the test line 301. The locking plate 404 can be manually slid to separate from the locking block 203, allowing the cover 2 to be opened for easy inspection of the test component 3 inside the housing 1. The user can slide the clamping plate 504 outward, which slides along the limiting rail 501, compressing the second spring 505. The user can then use the second anti-slip pad 506 and the first protective pad 405 to clamp the device onto the side panel of the distribution cabinet. At this time, the device is fixed by the elastic force of the second spring 505, further eliminating the need for one-handed operation and preventing the user experience from being limited to one-handed operation when testing transformers.

[0030] In this embodiment, the mounting foot 401, in conjunction with the threaded assembly, mounts the wire box 4 to the back of the housing 1. The mounting shaft 402 is used to limit the first spring 403. Under the elastic force of the first spring 403, the snap-fit ​​plate 404 and snap-fit ​​block 203 located in the slide groove 102 contact each other, limiting the cover 2.
