[0024] Embodiment 1

[0025] A leakage detection alarm comprises a fixed disk 7, an insulating tube 11 is fixedly connected to the side wall of the fixed disk 7, the insulating tube 11 is made of insulating material, the insulating tube 11 is transparent, a resistor 1 is slidably connected inside the insulating tube 11, one side of the resistor 1 is electrically connected to a conductive column 5, the conductive column 5 penetrates and is slidably connected to the side wall of the fixed disk 7, one end of the conductive column 5 is fixedly connected to a conductive sheet 6, the conductive sheet 6 is made of stainless steel, a magnetic ring 8 is fixedly connected to the side wall of the fixed disk 7, the magnetic ring 8 is fixedly connected to the annular edge of the fixed disk 7, a neon lamp 2 is slidably connected inside the insulating tube 11, one end of the neon lamp 2 is electrically connected to the resistor 1, a metal contact sheet 4 is fixedly connected to one end of the insulating tube 11, and a spring 3 is abutted between the side wall of the metal contact sheet 4 and the conductive end of the neon lamp 2.

[0026] The working principle of this embodiment is:

[0027] When in use, the fixing plate 7 can be directly fixed on the outer shell of the distribution cabinet through the magnetic ring 8, and the conductive sheet 6 can be against the side wall of the outer shell of the distribution cabinet. Whenever the distribution cabinet needs to be opened, the finger can first touch the metal contact sheet 4. When the distribution cabinet leaks electricity, the voltage on the distribution cabinet will pass through the conductive sheet 6, the resistor 1, the neon lamp 2, the spring 3 and the metal contact sheet 4, and then through the human body to connect to the ground to form a loop. At this time, the neon lamp 2 in the insulating tube 11 will light up, indicating that the distribution cabinet is leaking electricity.

[0028] Embodiment 2

[0029] The difference between Example 2 and Example 1 is that a grounding nail 10 is electrically connected to the side wall of the metal contact sheet 4 through a grounding wire 9. The grounding nail 10 is directly buried underground, so that one side of the metal contact sheet 4 is continuously grounded. There is no need for human fingers to touch the metal contact sheet 4. When the distribution cabinet leaks electricity, the neon lamp 2 in the insulating tube 11 will directly emit light.

[0030] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
