[0006] To achieve the above objectives, this utility model provides the following technical solution: a live display structure for a contact box, comprising a contact box body and a live display installed on the instrument door of a switch cabinet. The contact box body has a contact receiving cavity inside. One end of the contact box body is connected to a fixed base, and the other end of the contact box body is connected to a cable outlet box. One end of the cable outlet box has a cable outlet groove that communicates with the contact receiving cavity. The opening direction of the cable outlet groove is perpendicular to the central axis of the contact box body. An inductive sensor is embedded in the end of the contact box body near the cable outlet box.

[0007] Preferably, the side wall of the contact box body is provided with several convex and concave skirts along the axial direction.

[0008] Preferably, the contact box body is made of insulating material, which is epoxy resin.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model provides a way to visually display the energized status of an electrical system, making the testing operation simpler and improving work efficiency.

[0011] 2. This new type of equipment reduces the frequency of use of the electrical testing vehicle and trolley, extends the service life of the equipment, improves the safety performance of the electrical switch cabinet, and reduces maintenance costs. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example 1, by Figures 1-4 The present invention includes a contact box body 1 and a live display installed on the instrument door of a switch cabinet. The contact box body 1 has a contact receiving cavity 2 inside. One end of the contact box body 1 is connected to a fixing base 3, and the other end of the contact box body 1 is connected to a cable outlet box 4. One end of the cable outlet box 4 has a cable outlet groove 5 that communicates with the contact receiving cavity 2. The opening direction of the cable outlet groove 5 is perpendicular to the central axis of the contact box body 1. An inductive sensor 6 is embedded in the end of the contact box body 1 near the cable outlet box 4.

[0021] The side wall of the contact box body 1 is provided with several convex and concave skirts 7 along the axial direction. The skirts 7 can increase the creepage distance of the outer wall of the contact box body 1.

[0022] The contact box body 1 is made of insulating material, which is epoxy resin.

[0023] Working principle: First, the inductive sensor 6 is embedded in the end of the contact box body 1, and the live display is installed on the instrument door;

[0024] The inductive sensor 6 is embedded in the end of the contact box body 1 near the outlet box 4, maintaining a certain safe distance from the busbar;

[0025] When the busbar is energized, an electric field is generated around it. The inductive sensor 6 can sense this electric field and convert it into an electrical signal.

[0026] The inductive sensor 6 transmits the sensed electrical signal to the charged display;

[0027] After receiving the electrical signal transmitted by the inductive sensor 6, the live display will display the signal according to its strength and frequency.

[0028] If the busbar is energized, the energization indicator will display the corresponding energization status (such as indicator lights illuminating, energization information displayed on the screen, etc.);

[0029] If the busbar is not energized, the energized indicator will show a de-energized status (e.g., indicator lights are off, screen displays no power information, etc.);

[0030] The contact box body 1 is made of insulating material (such as epoxy resin) to ensure good insulation performance between the equipment and the live parts;

[0031] On the other hand, the side wall of the contact box body 1 is provided with several convex and concave skirts 7. These skirts can increase the creepage distance of the outer wall of the contact box body 1, prevent arc discharge and electrical breakdown, and further improve the safety performance of the equipment.
