[0002] In power systems, to facilitate unified and centralized management, the power distribution cables of more and more electrical equipment are concentrated in a distribution cabinet. The safety of the distribution cabinet has also become one of the concerns of users. Leakage fault detection devices are usually used to detect leakage faults in the distribution cabinet.

[0003] However, when existing leakage current detectors are used to test distribution cabinets outdoors, the connectors on the detectors are exposed without any protective structure. The main unit of the leakage current detector also lacks a structure for storing the connecting wires, which means that the connecting wires need to be stored separately when carried outdoors, making it inconvenient to use. Utility Model Content

One side of the main unit has a display screen and a control area, and the top has multiple wiring ports. The control area contains control buttons and a switch. The display screen, control buttons, and switch are electrically connected to the main unit. The lower end of the other side of the main unit has a mounting cavity. A cover plate is provided on the outside of the mounting cavity. The upper end of the cover plate is hinged to the outside of the mounting cavity, and the lower end is snapped into place. Symmetrical limit sleeves are arranged inside the lower part of the mounting cavity, and a support frame for fixing the cover plate is slidably fitted between two limit sleeves.

[0007] Preferably, the main body of the detector is hinged with fixed handles on both sides.

[0008] Preferably, a dustproof housing is provided on the top of the main unit of the detector and outside the wiring port. The top of the dustproof housing has an opening, and a matching pull plate is inserted and installed at the opening. A pull ring is fixed on the outside of the pull plate.

[0009] Preferably, a U-shaped fixing seat and an "I"-shaped winding post are sequentially installed on the inner wall of the mounting cavity.

[0010] Preferably, one side of the cover plate is provided with multiple blocks, and each block is provided with an arc-shaped groove for fixing the support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This leakage fault detection device for power distribution cabinet can protect the wiring ports when the main unit of the detector is not in use, making it easy to store plugs and connecting wires, thus facilitating its portability and use. It can also adjust the tilt angle when placed, improving the flexibility of use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution:

[0021] A leakage fault detection device for a power distribution cabinet includes a main unit 1. One side of the main unit 1 is equipped with a display screen 2 and a control area, and multiple wiring ports 5 are installed on the top. The control area is equipped with control buttons 3 and switch buttons 4. The display screen 2, control buttons 3 and switch buttons 4 are electrically connected to the main unit 1. The other side of the main unit 1 has a mounting cavity 6 at the lower end. A cover plate 7 is provided on the outside of the mounting cavity 6. The upper end of the cover plate 7 is hinged to the outside of the mounting cavity 6, and the lower end is snapped into the outside of the mounting cavity 6. Limiting sleeves 8 are symmetrically arranged inside the lower part of the mounting cavity 6. A support frame 9 for fixing the cover plate 7 is slidably sleeved between the two limiting sleeves 8.

[0022] In use, the back of the main unit 1 of the detector has a mounting cavity 6, which is used to store the plug and connecting wire of the detector. When the main unit 1 of the detector is not in use, the cover plate 7 can be opened manually. It should be noted that the back of the cover plate 7 has a slot for easy finger operation. Then, the plug and connecting wire are placed into the mounting cavity 6 for storage, and the cover plate 7 is closed. During use, the cover plate 7 can also be rotated to tilt the main unit 1 vertically. The tilt angle can be adjusted according to the needs of use. Then, the support frame 9 is rotated towards the cover plate 7 to support the cover plate 7, making the main unit 1 of the detector more stable and secure when placed.

[0023] The main unit 1 of the detector is hinged to both sides with fixed handles 10, which makes it easy to lift the main unit 1 of the detector with one hand for carrying.

[0024] A dustproof housing 11 is provided on the top of the main unit 1 of the detector and outside the wiring port 5. The top of the dustproof housing 11 has an opening, and a matching pull plate 12 is inserted and installed at the opening. A pull ring 13 is fixed on the outside of the pull plate 12. When not in use, the dustproof housing 11 can protect against dust and thus protect the wiring port 5. When in use, the pull plate 12 can be pulled out for easy wiring.

[0025] The inner wall of the mounting cavity 6 is equipped with a U-shaped fixing seat 14 and an "I"-shaped winding post 15. When not in use, the connecting wire can be wound around the winding post 15 and the plug can be placed in the fixing seat 14, which makes it easy to store.

[0026] The cover plate 7 has multiple stops 16 on one side. Each stop 16 has an arc-shaped groove for fixing the support frame 9. When the tilt angle of the detector host is adjusted, the support frame is rotated and one end of the support frame is inserted into the arc-shaped groove in the corresponding stop 16, which makes it easy to adjust the angle.

[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
