[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] A fault detection device for an intelligent drawer of a low-voltage switchgear cabinet, as Figures 1-3As shown in the figure, it includes a detector 1, a display 2, an indicator 3, a buckle 4, a sensor 5, a magnetic base 6, a first data cable 7, an upper clamping plate 8, a torsion spring 9, a second data cable 10, a grip 11, a detection needle 12, and a truss 13. The upper front side of the detector 1 is connected to the display 2. The lower front side of the detector 1 is rotatably connected to the indicator 3. Both the left and right sides of the detector 1 are connected with buckles 4. The buckles 4 are arc-shaped structures, which are convenient for clamping the sensor 5. The sensors 5 are clamped on the buckles 4. The lower sides of the sensors 5 are both connected with magnetic bases 6. The lower rear side of the detector 1 is connected with two left and right first data cables 7. The upper side of the first data cable 7 is connected with an upper clamping plate 8. Lower clamping plates are rotatably arranged on the upper clamping plates 8. Torsion springs 9 are connected between the clamping plates and the corresponding lower clamping plates. The upper sides of both the left and right sides of the detector 1 are connected with second data cables 10. The upper sides of the second data cables 10 are both connected with grips 11. The upper side of the grip 11 is connected with a detection needle 12. The upper rear side of the detector 1 is connected with a truss 13. Two jacks 14 are opened on the upper part of the detector 1.

[0019] When using the present utility model, first move the detector 1 near the low-voltage switchgear to be detected. When it is necessary to detect the running smoothness of the intelligent drawer, control the intelligent drawer to open, and then adsorb the detector 1 on the inner wall of the intelligent drawer through the magnetic base 6 of the sensor 5. Then control the intelligent drawer to be pulled open and closed. The sensor 5 is used to detect whether there are any phenomena such as no jamming or abnormal noise when the intelligent drawer is closed and opened. When it is necessary to detect the contact of the intelligent drawer, rotate and open the lower clamping plate on the clamping plate, and the torsion spring 9 deforms. Then move the lower clamping plate and the upper clamping plate 8 so that the contact is located between the lower clamping plate and the upper clamping plate 8. Then make the torsion spring 9 rebound, drive the lower clamping plate to rotate and reset, clamp the contact, and then make the detector 1 detect the line fault on the contact, and display the detected result on the display 2. When it is necessary to detect the contact point of the intelligent drawer, move the detection needle 12 to contact the contact point through the grip 11, and make the detector 1 detect the line fault on the contact point. The indicator 3 can indicate the voltage value on the contact or the contact point, and the display 2 can display the result of the fault detection, which is convenient for the staff to view. Thus, it plays a role in being able to facilitate various fault detections of the intelligent drawer of the low-voltage switchgear and improve the efficiency of the intelligent drawer. After the fault detection is completed, clamp the upper clamping plate 8 and the lower clamping plate on the truss 13, and insert the detection needle 12 into the jack 14 to prevent the upper clamping plate 8 and the detection needle 12 from being damaged.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
