Description

Technical Field

[0001] This utility model relates to the field of leakage current detection technology, and in particular to a leakage current monitoring device for grounding flat iron in transformer substations. Background Technology

[0002] Electrical fires are a major safety hazard in power systems. Leakage detection helps to detect potential electrical fire hazards in a timely manner, such as aging lines and damaged insulation. If these hazards are not eliminated in time, they may cause electrical fires, resulting in casualties and property damage. By detecting leakage, these problems can be identified and repaired in time, thereby reducing the risk of electrical fires.

[0003] However, there are some problems that urgently need to be solved in existing leakage current detection devices, especially grounding flat iron leakage current detection devices.

[0004] Firstly, from the perspective of the device's professionalism and specificity, few existing leakage current detection devices are specifically designed for grounding flat irons. This may lead to poor detection results, failing to accurately reflect the leakage current status of the grounding flat iron, and thus delaying the discovery and repair of potential hazards.

[0005] Secondly, some existing leakage current detection devices lack necessary protective mechanisms. This could pose a potential safety threat to personnel conducting the tests. For example, if the device lacks protective mechanisms during testing, personnel could suffer electric shock due to accidental contact with high-voltage lines or leakage points. Utility Model Content

[0006] To overcome the problem that the device is not very effective in detecting leakage current in grounding flat iron and lacks a protective mechanism.

[0007] The technical solution of this utility model is as follows: a grounding flat iron leakage current monitoring device for transformer substations, including a housing; it also includes a display screen and a protective component. The protective component is provided on the outside of the housing. A display screen for displaying data is provided on the upper front of the housing. An indicator light is provided at the lower end of the display screen. A detection element is provided on the back of the display screen. A counterweight is provided at the lower end of the detection element. A first outer shell is fixedly connected to the upper and lower ends inside the housing. A magnetic strip is fixedly connected inside the first outer shell. A movable plate is slidably connected to the middle position of the back of the housing. A movable rod is fixedly connected to the front end of the movable plate. A spring is fixedly connected to the outside of the movable rod. A second outer shell is fixedly connected to the outside of the spring. A detection plate is fixedly connected to the front end of the second outer shell.

[0008] Preferably, the outer casing 2 has holes at the corresponding positions of the moving rod, and the moving rod is slidably connected inside the outer casing 2.

[0009] Preferably, holes are provided at the corresponding positions of the detection plate and the moving rod, and the moving rod is slidably connected inside the detection plate.

[0010] Preferably, the magnet strip is made of neodymium magnet and its surface is provided with anti-slip pattern.

[0011] Preferably, the protective component includes a connector, which is fixedly connected to the outside of the housing. A locking element is provided at the lower end of the connector. A rotating element is rotatably connected inside the connector. A telescopic rod is fixedly connected to the outside of the rotating element. A handle is fixedly connected to the outside of the telescopic rod.

[0012] Preferably, a groove is provided at the position corresponding to the handle of the locking component, and the handle is slidably connected inside the locking component.

[0013] As a preferred option, the handle is made of rubber with a non-slip pattern on its surface.

[0014] The beneficial effects of this utility model are as follows: By pulling the handle out of the locking part and extending the telescopic rod by pulling the handle, the box body is attached to the grounding flat iron. The box body is then attached and fixed to the grounding flat iron by the magnetic strip. The flat iron pushes the moving plate to move, which in turn moves the moving rod. This causes the moving rod to contact the detection plate and transmit a signal to the detection element. The detection element then detects the signal and displays the detection result on the display screen and indicator lights. This helps to solve the problems of the device's weak targeting of grounding flat iron leakage detection and the lack of a protective mechanism. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a grounding flat iron leakage current monitoring device for transformer substations, including a housing 1; it also includes a display screen 201 and a protective component. The protective component is provided on the outside of the housing 1. A display screen 201 for displaying data is provided on the upper front of the housing 1. An indicator light 202 is provided at the lower end of the display screen 201. A detection element 203 is provided on the back of the display screen 201. A counterweight 204 is provided at the lower end of the detection element 203. A first outer shell 205 is fixedly connected to the upper and lower ends inside the housing 1. A magnetic strip 206 is fixedly connected inside the first outer shell 205. A movable plate 207 is slidably connected to the middle of the back of the housing 1. A movable rod 208 is fixedly connected to the front end of the movable plate 207. A spring 209 is fixedly connected to the outside of the movable rod 208. A second outer shell 210 is fixedly connected to the outside of the spring 209. A detection plate 211 is fixedly connected to the front end of the second outer shell 210. The housing 1 is fixedly attached to the grounding flat iron by the magnetic strip 206. On the grounding flat iron, the flat iron pushes the moving plate 207 to move, which in turn drives the moving rod 208 to move. This causes the moving rod 208 to contact the detection plate 211 and transmit a signal to the detection element 203. The detection element 203 then detects the signal and displays the result on the display screen 201 and the indicator light 202. The outer shell 210 has holes at the corresponding positions of the moving rod 208. The moving rod 208 is slidably connected inside the outer shell 210. The moving rod 208 helps to connect the moving plate 207 to transmit the signal to the detection plate 211. The detection plate 211 has holes at the corresponding positions of the moving rod 208. The moving rod 208 is slidably connected inside the detection plate 211. The detection plate 211 helps to transmit the signal to the detection element 203. The magnet strip 206 is made of neodymium magnet and has an anti-slip pattern on its surface. The magnet strip 206 helps to tightly fit the box 1 against the outside of the grounding flat iron.

[0023] Please see Figure 5 In this embodiment, the protective component includes a connector 301, which is fixedly connected to the outside of the box 1. A locking member 302 is provided at the lower end of the connector 301. A rotating member 303 is rotatably connected inside the connector 301. A telescopic rod 304 is fixedly connected to the outside of the rotating member 303. A handle 305 is fixedly connected to the outside of the telescopic rod 304. By pulling the handle 305 out of the locking member 302 and pulling the handle 305, the telescopic rod 304 is extended. By holding the handle 305, the box 1 is pressed against the grounding flat iron for testing. A groove is provided at the corresponding position of the locking member 302 and the handle 305. The handle 305 is slidably connected inside the locking member 302. The locking member 302 helps to fix the handle 305 when not in use, making the device easy to carry. The handle 305 is made of rubber and has an anti-slip pattern on its surface. The handle 305 helps to increase the friction when gripping, thus protecting the user.

[0024] During operation, by pulling the handle 305 out of the locking part 302, the telescopic rod 304 is extended by pulling the handle 305. By holding the handle 305, the box 1 is attached to the grounding flat iron. The box 1 is attached and fixed to the grounding flat iron by the magnetic strip 206. The flat iron pushes the moving plate 207 to move, which in turn drives the moving rod 208 to move. This causes the moving rod 208 to contact the detection plate 211 and transmit a signal to the detection element 203. The detection element 203 then detects the signal and displays the detection result on the display screen 201 and the indicator light 202.

[0025] Through the above steps, by pulling the handle 305 out of the locking part 302, pulling the handle 305 to extend the telescopic rod 304, holding the handle 305 to attach the box 1 to the grounding flat iron, and fixing the box 1 to the grounding flat iron by the magnetic strip 206, the flat iron pushes the moving plate 207 to move and simultaneously drives the moving rod 208 to move, so that the moving rod 208 contacts the detection plate 211 to transmit a signal to the detection element 203, and then the detection element 203 detects and displays the detection result on the display screen 201 and the indicator light 202. This helps to solve the problem that the device is not very targeted in detecting leakage current of the grounding flat iron and lacks a protective mechanism.
