Description

Technical Field

[0001] This utility model relates to the field of grounding resistance technology, and more specifically, to an intelligent online monitoring device for grounding resistance. Background Technology

[0002] Grounding resistance is the resistance encountered when current flows from a grounding device into the earth and then through the earth to another grounding body or diffuses to a distance. The grounding resistance value reflects the quality of contact between the electrical device and the ground and reflects the scale of the grounding network. Grounding technology was initially introduced as a protective measure to prevent electrical or electronic equipment from being struck by lightning. Its purpose is to guide the lightning current generated by lightning strikes into the earth through lightning rods, thereby protecting buildings. At the same time, grounding is also an effective means of protecting personal safety. When a phase wire comes into contact with the equipment casing for some reason, a dangerous voltage will be generated on the equipment casing. The resulting current will flow to the earth through the protective ground wire, thus protecting personal safety.

[0003] This application addresses the shortcomings of existing technologies. In existing intelligent grounding resistance monitoring devices, the installation of the monitoring instrument requires the installation of a current and voltage acquisition device, which is time-consuming. Furthermore, a large number of monitoring instruments are required for grounding resistance monitoring, resulting in low installation efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an intelligent online monitoring device for grounding resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent online monitoring device for grounding resistance, comprising a monitoring instrument body, a second controller, and a power supply.

[0009] As a preferred embodiment of this utility model, a fixed shaft is fixedly connected between the two sets of support plates, and the outer wall of the fixed shaft is rotatably connected to the collection ring.

[0010] As a preferred embodiment of this utility model, a data acquisition module is fixedly installed on one of the data acquisition rings, and a wiring terminal is installed at the bottom of the other data acquisition ring, and the wiring terminal is electrically connected to the data acquisition module.

A horizontal plate 19 is fixedly connected to the side of the limiting column 20 away from the collection ring 9. A locking rod 23 is slidably connected to the horizontal plate 19. A locking groove 22 is opened on the side of the hook 16 away from the collection ring 9, and the locking groove 22 is adapted to the locking rod 23. The two collection rings 9 are initially closed and fixed by the cooperation of the hook 16 and the limiting column 20. The hook 16 is limited by the locking rod 23 and the locking groove 22, which improves the stability of the fixation between the two collection rings 9.

[0017] The bottom of the hook 16 is fixedly connected to an arc-shaped block 21. One of the collection rings 9 has an arc-shaped groove 18, which is adapted to the arc-shaped block 21. The arc-shaped groove 18 is located below the side of the limiting post 20 away from the fixed post 17. The arc-shaped groove 18 and the arc-shaped block 21 facilitate the rotation of the hook 16 and also facilitate the two collection rings 9 to come close to each other.

[0018] The end of the lever 23 extending out of the top of the horizontal plate 19 is fixedly connected to a fixed plate 25. The bottom of the fixed plate 25 is fixedly connected to a spring 24 that is sleeved with the lever 23, and the other end of the spring 24 is fixedly connected to the horizontal plate 19. The spring 24 facilitates the reset of the lever 23 and allows the lever 23 to enter the slot 22 to limit the hook 16.

[0019] The mounting plate 2 and the mounting plate 3 are provided with mounting grooves 5 on the side of each other. The mounting plate 3 away from the mounting plate 2 is threaded with symmetrically distributed fastening bolts 13, and the fastening bolts 13 are threaded to the mounting plate 2. The fastening bolts 13 facilitate the connection and fixation between the mounting plate 2 and the mounting plate 3. The mounting grooves 5 facilitate the installation of the detector to the position of the test point.

[0020] Among them, a fixed shaft 11 is fixedly connected between the two sets of support plates 12. The outer wall of the fixed shaft 11 is rotatably connected to the acquisition ring 9, and the acquisition ring 9 can be rotated through the fixed shaft 11.

[0021] One of the acquisition rings 9 has an acquisition module 10 fixedly installed on it, and the other acquisition ring 9 has a terminal block 26 installed at its bottom, and the terminal block 26 is electrically connected to the acquisition module 10.

[0024] In this application, during installation, the fixing plate 2 and the mounting plate 3 are fixed by the fastening bolts 13, and then the main body 1 of the monitor is installed at the point to be measured. The two acquisition rings 9 are rotated to close, and then the grounding resistor is connected. The hook 16 is rotated to hang on the limiting post 20. During the rotation of the hook 16, the arc block 21 enters the arc groove 18 to close and fit the two acquisition rings 9. When the inner wall of the hook 16 abuts against the limiting post 20, the spring 24 resets and the locking rod 23 resets, and then the locking rod 23 enters the locking groove 22 to limit the hook 16, thus completing the installation. This facilitates installation and improves installation efficiency. In this application, during monitoring, the current and voltage information of the monitoring point are collected by two acquisition modules 10 respectively. Based on the voltage and current data, the resistance information is displayed on the display screen 6 so that maintenance personnel can check whether the grounding resistance status is abnormal. The first controller 8 can be an existing microprocessor used to process the data collected by the acquisition unit 27 and perform offline control. The second controller 14 can be a computer. After the second controller 14 is connected to the communication module 7, the remote control of the monitoring instrument body 1 can be realized, and the operating status of the grounding resistance can also be remotely monitored, thus realizing online monitoring of the grounding resistance.
