Description

Technical Field

[0001] This utility model relates to the technical field of low-current line selection devices, specifically, to a low-current line selection device with anti-electric shock properties. Background Technology

[0002] Low-current fault location devices are key equipment for detecting and locating faulty lines in power systems, playing a vital role in the safe and stable operation of distribution networks. With the increasing demands for intelligence and reliability in power systems, higher standards are being placed on the performance and stability of low-current fault location devices.

[0003] However, existing low-current line selection devices have many problems in practical use. On the one hand, the electronic components inside the device generate a lot of heat during long-term operation. Existing heat dissipation structures often have low heat dissipation efficiency, and the heat cannot be dissipated in time, resulting in excessively high internal temperatures, which affects the normal operation and lifespan of the components. On the other hand, in some high-humidity working environments, the lack of effective moisture-proof measures allows humid air to easily enter the device, causing moisture damage to the electronic components and reducing the reliability of the device. In addition, when not in use, dust and foreign objects can easily enter the wiring holes at the rear of the device, which not only affects the stability and conductivity of the wiring, but may also cause short circuits and other faults, increasing equipment maintenance costs and safety hazards. Utility Model Content

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-5As shown, it illustrates an embodiment of the present invention of a low-current line selection device for preventing electric shock, comprising: a mounting housing body 1, a line selection device body 2 fixedly installed inside the mounting housing body 1, a heat dissipation mechanism installed inside the mounting housing body 1, and a PLC control panel 4 fixedly installed on the outer wall of the front end of the mounting housing body 1.

[0030] Wiring holes 3: Several sets of wiring holes 3 are fixedly installed at the rear end of the mounting shell body 1. A protective mechanism is installed on the outer wall of the rear end of the mounting shell body 1. A moisture-proof mechanism is installed at the top of the mounting shell body 1.

[0031] For example, such as Figure 2 As shown, the heat dissipation mechanism includes mounting brackets 5, cooling fans 6, and heat dissipation slots 7. Mounting brackets 5 are fixedly installed on both sides of the inside of the mounting shell body 1. Cooling fans 6 are fixedly installed on both sets of mounting brackets 5. Several sets of heat dissipation slots 7 are vertically opened on both sides of the mounting shell body 1. A protective net 8 is fixedly installed inside each set of heat dissipation slots 7.

[0032] For example, such as Figure 3 As shown, the protective mechanism includes a mounting frame 9, an L-shaped plate 10, a handle 11, a first magnetic attracting plate 12, a first magnetic attracting plate 13, a second magnetic attracting plate 14, and a second magnetic attracting plate 15. The mounting frame 9 is fixedly installed on the outer wall of the rear end of the mounting housing body 1 at the position outside the wiring hole 3. The L-shaped plate 10 is rotatably installed on the top of the mounting frame 9. The handle 11 is fixedly installed on the outer wall of the rear end of the L-shaped plate 10. The first magnetic attracting plate 12 is fixedly installed on the outer wall of the rear end of the mounting housing body 1. The first magnetic attracting plate 13 is fixedly installed on the L-shaped plate 10 at the corresponding position of the first magnetic attracting plate 12. The second magnetic attracting plate 14 is fixedly installed on the outer wall of the bottom end of the L-shaped plate 10. The second magnetic attracting plate 15 is fixedly installed on the mounting frame 9 at the corresponding position of the second magnetic attracting plate 14. The inner wall of the mounting housing body 1 is coated with an insulating layer made of polycarbonate material. Mounting plates 23 are fixedly installed on the bottom ends of the outer walls on both sides of the mounting housing body 1. Each set of mounting plates 23 has mounting holes 24.

[0033] In some examples, for ease of control, the line selection device body 2 and two sets of cooling fans 6 are electrically connected to the PLC control panel 4 and to an external power supply. When using the device, the operator can activate the cooling fans 6 to effectively dissipate the heat generated during the operation of the low-current line selection device through the heat dissipation slots 7, thereby reducing the internal temperature of the device and ensuring that the internal electronic components operate stably in a suitable temperature environment, effectively extending the service life of the components. When the device is not in use, the operator can use the second magnetic attracting sheet 14 and the second magnetic attracting sheet 15 to magnetically attract each other, thereby fixing the L-shaped plate 10. This effectively prevents dust and foreign objects from entering the wiring hole 3 when the device is not in use, protecting the cleanliness of the wiring hole 3, ensuring the stability and good conductivity of the wiring, and reducing the risk of poor contact, short circuits, and other faults caused by dust accumulation. Finally, in this device, the insulating layer coated on the inner wall of the mounting shell body 1 improves the insulation performance of the mounting shell body 1, thereby improving the protection against electric shock to a certain extent.

[0034] like Figure 4 As shown, this invention illustrates a low-current line selection device for protection against electric shock in another embodiment of the present invention. The moisture-proof mechanism includes a mounting groove 16, a drawer 17, a fitting groove 18, a fitting block 19, a through hole 20, a grooved handle 21, and a mounting screw 22. The mounting shell body 1 has a mounting groove 16 at its top end, and the drawer 17 is slidably installed inside the mounting groove 16. The drawer 17 has a grooved handle 21 at its top end. The mounting shell body 1 has fitting grooves 18 at both the front and rear ends of the mounting groove 16. The drawer 17 has fitting blocks 19 that match the fitting grooves 18 fixedly installed at both the front and rear ends. The drawer 17 has several sets of through holes 20 on its right side. The top ends of two sets of fitting blocks 19 are vertically threaded with mounting screws 22. The top ends of two sets of fitting grooves 18 have connection holes that match the mounting screws 22. Each set of fitting blocks 19 has a sealing gasket fixedly installed at the connection between its outer surface and the corresponding fitting groove 18.

[0035] In some examples, in this device, the operator can place the desiccant pack in the placement drawer 17, then slide the placement drawer 17 into the mounting slot 16, and then fix the fitting block 19 fixedly installed on the placement drawer 17 to the fitting slot 18 by the mounting screw 22, so that the placement drawer 17 can be fixed. Through the above settings, the moisture entering the device can be absorbed in real time, maintaining a dry environment inside the device, effectively preventing electronic components from getting damp, and avoiding problems such as short circuits and component corrosion caused by moisture.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
