[0031] Reference Figures 1-8This embodiment provides a distribution network line loss analysis device, including...

[0032] The analyzer body 300, connected to the top of the mounting component 201, utilizes the DMP-3211 line protection and control device. This device integrates multiple principles, including three-stage instantaneous overcurrent protection, overcurrent protection, zero-sequence current protection, and directional protection. For example, the three-stage instantaneous overcurrent protection can quickly clear severe faults near the power source during a short circuit, ensuring line safety. In substations, it provides comprehensive protection and monitoring for transmission and distribution lines, integrating with substation automation systems for remote operation and centralized management. In distribution networks, it can promptly detect and isolate faults, minimizing outage areas, and, combined with distribution automation systems, automatically locate, isolate, and restore power supply to faults. For industrial enterprises with high power supply reliability requirements, it ensures the safe operation of internal power lines, optimizes power consumption plans, and reduces energy consumption.

[0033] The moving component 200 includes a mounting component 201, a rolling component 202 disposed on one side of the mounting component 201, a connecting component 203 disposed on one side of the mounting component 201, and a pushing component 204 disposed on the inner wall of the mounting component 201. When the moving component 200 is not in use, the connecting component 203 is hidden at the bottom of the analyzer body 300. When the analyzer body 300 needs to be moved, the analyzer body 300 is lifted and the connecting component 203 is rotated. The connecting component 203 will drive the pushing component 204 to move downward, and the pushing component 204 will push the rolling component 202 to move downward. At this time, the pushing component 204 will abut against the rolling component 202. Maintenance personnel can move the analyzer body 300 by pulling the connecting component 203. In this way, the analyzer body 300 can be moved quickly without the aid of other transportation tools, saving transportation time, improving inspection efficiency, and also making it convenient for users to carry the analyzer body 300.

[0034] As an alternative embodiment, a more specific illustration is provided of how to facilitate the user's movement of the analyzer body 300.

[0035] Mounting component 201 includes a housing 201-1, a movable groove 201-2 formed on one side of the housing 201-1, a first fixed wheel 201-3 formed on one side of the housing 201-1, and a limiting groove 201-4 formed on one side of the housing 201-1. The overall shape of the housing 201-1 is as follows: Figure 5 As shown, it is a symmetrical workpiece, with moving grooves 201-2 and limiting grooves 201-4 symmetrically arranged on both sides. At the same time, a first fixed wheel 201-3 is fixedly connected to the top of each moving groove 201-2 by bolts.

[0036] The bottom of the mounting component 201 is connected to the bottom of the analyzer body 300. The first fixed wheel 201-3 is set on the top of the moving groove 201-2. The housing 201-1 is fixed to the bottom of the analyzer body 300 by bolts. Two symmetrical housings 201-1 are installed on the bottom of the analyzer body 300.

[0037] It should be noted that the first fixed wheel 201-3 is an I-shaped roller, which is fixed to the mounting part 201 by bolts.

[0038] The rolling element 202 includes a roller 202-1, a rotating shaft 202-2 that passes through the middle of the roller 202-1 and is rotatably connected to the inner wall of the roller 202-1, and a second fixed wheel 202-3 connected to one side of the rotating shaft 202-2. There are several rollers 202-1, and one roller 202-1 is installed on each side of the housing 201-1. There are several second fixed wheels 202-3. Both sides of each rotating shaft 202-2 are connected to the corresponding second fixed wheel 202-3 by bolts.

[0039] The outer wall of the rotating shaft 202-2 is slidably connected to the outer wall of the moving groove 201-2. An elastic element 205 is sleeved on the outer wall of the first fixed wheel 201-3. The other side of the elastic element 205 is sleeved on the outer wall of the second fixed wheel 202-3. The two sides of the rotating shaft 202-2 are respectively connected to the corresponding moving groove 201-2. The rotating shaft 202-2 can move within the moving groove 201-2. The roller 202-1 is located in the middle position of the rotating shaft 202-2. Therefore, the roller 202-1 is confined inside the housing 201-1 and can move up and down within the housing 201-1.

[0040] It should be noted that the first fixed wheel 201-3 and the second fixed wheel 202-3 are connected by an elastic element 205. Therefore, when the second fixed wheel 202-3 moves, it will pull the elastic element 205. Here, the elastic element 205 is an elastic rope, which will generate a certain rebound force when it is pulled.

[0041] The connector 203 includes a long rod 203-1 rotatably connected to one side of the housing 201-1, a telescopic rod 203-2 disposed on one side of the long rod 203-1, a cam 203-3 disposed on the outer wall of the long rod 203-1, and a special-shaped rod 203-4 disposed at one end of the telescopic rod 203-2. The long rod 203-1 has telescopic rods 203-2 on both sides. The telescopic rod 203-2 is a telescopic rod consisting of a large-diameter pipe and a small-diameter pipe. The large-diameter pipe is sleeved on the outer wall of the small-diameter pipe. The small-diameter pipe cannot be separated from the large-diameter pipe. There is a certain friction between the two. The ends of the two telescopic rods 203-2 are respectively fixedly connected to the two ends of the special-shaped rod 203-4 by welding.

[0042] It should be noted that cams 203-3 are fixedly installed at both ends of the long rod 203-1 by welding, such as Figure 4 As shown, one side of the cam 203-3 is set as a plane. When the shaped rod 203-4 faces to the left, the plane end of the cam 203-3 will face upward.

[0043] The pusher 204 includes a movable plate 204-1, a pressure rod 204-2 disposed on one side of the movable plate 204-1, and a limiting rod 204-3 disposed on one side of the movable plate 204-1. The movable plate 204-1 has the following shape: Figure 8 As shown, it is a symmetrical workpiece, and the pressure rod 204-2 and the moving plate 204-1 are integrated.

[0044] The outer wall of the movable plate 204-1 is slidably connected to the inner wall of the housing 201-1. The top of the movable plate 204-1 contacts the bottom of the cam 203-3. The outer wall of the limiting rod 204-3 is slidably connected to the inner wall of the limiting groove 201-4. The bottom of the pressure rod 204-2 contacts the top of the second fixed wheel 202-3. When it is necessary to move the analyzer body 300, the irregular rod 203-4 is rotated to the left of the analyzer body 300, thereby causing the long rod 203-1 to drive the cam 203-3 to rotate. Because when the irregular rod 203-4 is located on the bottom right side of the analyzer body 300, the flat end of the cam 203-3 is facing downwards, so the cam... 203-3 will not squeeze the moving plate 204-1. When the long rod 203-1 drives the cam 203-3 to rotate, the circumferential area of ​​the cam 203-3 will squeeze the moving plate 204-1, and the moving plate 204-1 will move downward. At this time, the pressure rod 204-2 will press down the second fixed wheel 202-3, causing the roller 202-1 to move downward. Then, with the support of the moving plate 204-1 and the pressure rod 204-2, the four rollers 202-1 can support the analyzer body 300. Then, the analyzer body 300 can be moved by pulling the special rod 203-4.

[0045] This embodiment provides an extension mechanism, including,

[0046] The lifting assembly 100 includes a handle 101, a connecting rod 102 disposed on one side of the handle 101, and a connecting sleeve 103 disposed on one side of the connecting rod 102. A sliding groove 104 penetrating the connecting rod 102 is formed on one side of the connecting rod 102, and a connecting channel 105 penetrating the outer wall of the connecting sleeve 103 is formed on one side of the connecting sleeve 103. The sliding groove 104 and the connecting channel 105 are interconnected. For example... Figure 1As shown, the inner wall of the connecting channel 105 is rotatably connected to the outer wall of the shaped rod 203-4. When the analyzer body 300 is pulled normally, the handle 101 can be pulled directly to pull the analyzer body 300. However, if the analyzer body 300 needs to be pulled diagonally like a suitcase due to scenario requirements, the lifting assembly 100 can be rotated so that the shaped rod 203-4 faces the sliding groove 104. At this time, the connecting sleeve 103 is located on the far left. Pulling the connecting sleeve 103 causes the sliding groove 104 to slide on the shaped rod 203-4, eventually causing one side of the handle 101 to contact the shaped rod 203-4. Here, the cross-sectional shape of the shaped rod 203-4 is elliptical, and both its upper and lower sides are provided with flat ends. Therefore, when the shaped rod 203-4 contacts one side of the handle 101, the lifting assembly 100 cannot be rotated. At this time, one end of the analyzer body 300 can be lifted by the lifting assembly 100, thereby realizing the diagonal pulling of the analyzer body 300.

[0047] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
