[0002] Line loss, referred to as line loss, is the energy loss caused by the transmission of electric energy through transmission lines. Among them, leakage caused by damage to the line shielding layer is a common form of line loss. A multimeter is often used to check and detect the line loss.

[0003] When an existing multimeter is used for line leakage detection, it is usually necessary to manually hold the multimeter and the test leads for operation. However, since the test leads are divided into black and red, the operator not only needs to hold the multimeter body but also needs to hold the two test leads separately when using it, which seriously affects the operation steps, greatly reduces the convenience of using the device, and thus affects its detection efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a cable line loss detection component for power engineering, so as to solve the problem proposed in the above background technology that not only the multimeter body needs to be held in hand, but also two test leads of the sub-meter need to be held in hand, which seriously affects its operation steps, greatly reduces the convenience of using the device, and thus affects its detection efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a cable line loss detection component for electric power engineering, comprising:

[0011] Preferably, a stepped rotating groove is provided inside the rotating sleeve, and the rotating shaft and the rotating sleeve are connected in a damped rotation manner.

[0012] Preferably, the support plate is in a rectangular structure, the corners of the support plate are in an arc-shaped structure, and the thickness of the sponge pad is three times the thickness of the support plate.

[0014] Compared with the prior art, the beneficial effect of the utility model is that the new device can be worn on the arm through the cooperation between the tightening belt and the support plate, thereby freeing both hands to hold the test lead, thereby improving the convenience of using the device.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides an embodiment: a cable line loss detection component for electric power engineering, comprising:

[0025] A multimeter body 1, a winding shaft 2 and a U-shaped pipe clamp 3 are fixedly connected to the rear side of the multimeter body 1, a test lead connecting line 4 is wound around the outside of the winding shaft 2, and the test lead connecting line 4 can be wound and stored by setting the winding shaft 2 and the U-shaped pipe clamp 3, and the test lead can be clamped and limited at the same time;

[0026] Rotating shaft 5, rotating shaft 5 is fixedly connected to the rear side of multimeter body 1, the outer part of rotating shaft 5 is sleeved with rotating sleeve 6, the outer wall of rotating sleeve 6 is fixedly connected with supporting plate 7, the other side of supporting plate 7 is fixedly connected with sponge pad 8, and both ends of supporting plate 7 are connected with tightening belt 9. Through the setting of this structure, the multimeter body 1 can be worn on the arm when in use, so as to facilitate the detection by holding the test pen and improve the convenience of using the device.

[0027] Furthermore, two groups of winding shafts 2 and U-shaped tube clamps 3 are provided, and each group of winding shafts 2 and U-shaped tube clamps 3 is jointly equipped with a group of test lead connection lines 4. A test lead is provided at one end of the test lead connection line 4, and the test lead is clamped inside the U-shaped tube clamp 3 to facilitate the clamping and positioning of the test lead.

[0028] Furthermore, each group of winding shafts 2 is provided with four, and the four winding shafts 2 are distributed in a rectangular shape, each group of U-shaped tube clamps 3 is provided with two, and the two U-shaped tube clamps 3 are distributed up and down, and the size of the upper U-shaped tube clamp 3 is larger than the size of the lower U-shaped tube clamp 3. Through the rectangular distribution of the winding shafts 2, the winding length is increased, so that the entire winding and storage of the line can be completed. At the same time, through the upper and lower size distribution setting of the U-shaped tube clamps 3, the conical structure of the test lead can be effectively matched for clamping and positioning, thereby ensuring the stability of the test lead positioning. At the same time, after the test lead is plugged in, it is hidden between the support plate 7 and the multimeter body 1 to avoid collision.

[0029] Furthermore, the rotating shaft 5 is located at the center position of the rear side of the multimeter body 1, the rotating shaft 5 is stepped, and the outer wall of the rotating shaft 5 is wrapped with a soft rubber pad, a step-type rotating groove is opened inside the rotating sleeve 6, and the rotating shaft 5 and the rotating sleeve 6 are connected in a damping rotation. By setting the soft rubber pad, the rotation damping effect of the rotating shaft 5 and the rotating sleeve 6 is improved, thereby ensuring the stability of the multimeter body 1 after rotation.

[0030] Furthermore, the support plate 7 is of a rectangular structure, and the corners of the support plate 7 are of an arc-shaped structure. The thickness of the sponge pad 8 is three times the thickness of the support plate 7. The two ends of the tightening belt 9 are respectively fixedly connected to the two ends of the support plate 7, and the thickness of the tightening belt 9 is equal to the thickness of the support plate 7. The height of the winding shaft 2 is less than the sum of the thicknesses of the rotating sleeve 6 and the support plate 7, thereby avoiding the excessive length of the winding shaft 2 affecting the wearing of the multimeter body 1.

[0031] Working principle: The multimeter body 1 and the test lead connection circuit 4 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to technical personnel in this field, so they will not be repeated here. When using the utility model, first take out the test lead connection circuit 4, plug it into the multimeter body 1, further put the support plate 7 and the tightening belt 9 on the user's arm, and rotate the multimeter body 1 to make it at the best observation angle. First, connect one end of the cable with a breakpoint to the 220V live wire, and leave the other end hanging in the air. Adjust the gear of the multimeter body 1 to the AC 2V voltage gear, and then start from the live wire access end of the faulty cable. Hold the black test lead in one hand, and slowly slide the red test lead along the insulation layer of the faulty cable. The voltage value at the cable without a breakpoint is about 0.445V. When the red test lead moves to a certain place, the voltage value displayed by the multimeter drops sharply to 1 / 10 of the normal voltage. At this point, it can be basically determined that the breakpoint is 15 cm forward of the live wire access end at this position.
