Description

Technical Field

[0001] The utility model relates to the technical field of power distribution network, in particular to a contact network terminal voltage monitoring device. Background Art

[0002] The voltage at the end of the grid refers to the voltage at the load node at the farthest end of the grid or the farthest from the power source in the power system. During the power transmission process, a voltage drop will occur when the current passes through the transmission line and transformer equipment. As the current flows from the power source to the end of the grid, the voltage will gradually decrease due to the influence of line impedance. Therefore, the voltage at the end of the grid is usually a relatively low voltage point in the power system. The size of the voltage at the end of the grid is of great significance to the stable operation of the power system and the normal operation of electrical equipment.

[0003] The contact network end voltage monitoring device is a device used to measure, analyze and monitor the voltage status of the power grid end in real time.

[0032] Specifically, the voltage line is connected through the wiring hole 3 of the sealed shell 1, and the fixing buckle 1 4 and the fixing buckle 2 5 are used to ensure the stable connection of the wires. After the voltage signal is converted into an electrical signal by the sensor 14, it is processed by the monitoring mechanism 12 and converted into a digital signal for accurate measurement. The processed data is stored in the storage card 13 and intuitively displayed through the display screen 11. The communication mechanism 15 is responsible for transmitting the data to the remote monitoring center and supports multiple communication methods. The sealed shell 1 and the cover plate 9 protect the internal components from external interference and improve the stability of the equipment. The wiring seat 7 and the plug socket 8 facilitate the connection and expansion of the equipment. The fixing mechanisms 2 are fixed and connected at the four corners of the outer wall of the sealed shell 1. The main function of these fixing mechanisms 2 is to stabilize and fix the voltage monitoring device. In order to further enhance the stability and safety of the device, the fixing buckle 1 4 and the fixing buckle 2 5 are respectively located on one side of the outer wall of the sealed shell 1, and are fixedly connected with a rotating shaft 16.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 2 includes a fixing plate 201, which is fixedly connected to the four corners of the outer wall of the sealing shell 1. A fixing rod 202 is rotatably connected to the middle of the inner wall of the fixing plate 201, and a bolt 203 is rotatably connected to one side of the inner wall of the fixing rod 202. A fixing ring 204 is fixedly connected to the bottom of the outer wall of the fixing plate 201. The bolt 203 is slidably connected to the middle of the inner wall of the fixing ring 204.

[0034] Specifically, the fixing plate 201 is installed on the outer wall of the sealing shell 1 to provide positioning and connection. The fixing rod 202 is rotatably connected to the fixing plate 201, and the angle can be adjusted to meet different installation requirements. By tightening the nut 205, the bolt 203 drives the fixing rod 202 to rotate to achieve the tightening of the sealing shell 1. The connecting rod 206 provides auxiliary support to enhance stability and ensure that the sealing shell 1 is firmly fixed. The inner bottom wall of the sealing shell 1 fixes the gasket 18, and the top of the outer wall of this gasket 18 is connected to the bottom plate 19 to ensure the stability and sealing between the sealing shell 1 and the bottom plate 19. In addition, the sealing shell 1 and the right side of the inner wall of the cover plate 9 are each fixedly connected with a hinge 20. The two hinges 20 can rotate relative to each other so that the cover plate 9 can be flexibly opened and closed. On the adjacent side of the inner wall of the two hinges 20, a fixing block 21 is also rotatably connected. Such a structure not only enhances the stability of the hinge 20, but also provides a reliable fulcrum for the opening and closing of the cover plate 9.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A support plate 22 is fixedly connected to one side of the outer wall of the monitoring mechanism 12, a warning light 23 is fixedly connected to the top of the outer wall of the support plate 22, a sealing strip 24 is fixedly connected to the bottom of the outer wall of the cover plate 9, a sealing groove 25 is opened at the top of the inner wall of the sealing shell 1, and connecting plates 26 are fixedly connected at the four corners of the bottom of the sealing shell 1, and fixing holes 27 are opened in the middle of the inner walls of the multiple connecting plates 26;

[0036] Specifically, the monitoring mechanism 12 supports the warning light 23 through the support plate 22. When an abnormal voltage is detected, the monitoring mechanism 12 controls the warning light 23 to light up as a warning. The cover plate 9 cooperates with the sealing groove 25 on the top of the inner wall of the sealing shell 1 by relying on the sealing strip 24 at the bottom to play a good sealing role, preventing dust, water vapor, etc. from entering the shell and affecting the operation of the monitoring mechanism 12 components. The connecting plates 26 at the four corners of the bottom of the sealing shell 1 and the fixing holes 27 opened in the middle of the inner wall can be used to firmly install the entire monitoring device at a designated position with the help of bolts 203.

[0037] Working principle: The voltage circuit to be measured is connected through the wiring holes 3 on the left and right sides of the sealed shell 1. The fixing buckle 1 4 and the rotatable fixing buckle 2 5 on the outer wall of the wiring hole 3 are used to fix the connected wires to prevent the wires from loosening and falling off, ensuring a stable electrical connection. After the wires are connected, the voltage signal is transmitted to the inside of the sealed shell 1. The sensor 14 is connected to the voltage circuit to be measured, responsible for sensing the voltage signal and converting it into an electrical signal. The monitoring mechanism 12 analyzes and processes the electrical signal transmitted by the sensor 14, amplifies, filters, performs analog-to-digital conversion and other operations on the signal, and converts the analog voltage signal into a digital signal for subsequent accurate measurement and analysis. The data processed by the monitoring mechanism 12 is transmitted to the storage card 13 for storage on the one hand, so as to facilitate subsequent query and analysis of historical data. On the other hand, it is transmitted to the display screen 11, and the display screen 11 displays the data in an intuitive way. The current voltage value and voltage fluctuation information are displayed on the LCD screen 11, which is convenient for the staff to directly view on site. The communication mechanism 15 is responsible for transmitting the monitored data to the remote monitoring center or other equipment, and can transmit data in a wired or wireless manner to achieve remote real-time monitoring and monitoring of the network end voltage. The sealing shell 1 and the rotatably connected cover plate 9 work together to provide sealing protection for the internal structure to prevent external factors such as dust, water vapor and electromagnetic interference from affecting the normal operation of the equipment, thereby improving the stability and reliability of the equipment. The wiring seat 7 and the plug socket 8 provide convenience for the connection of other related equipment, which is convenient for expansion or docking with other equipment;

[0038] The fixing plate 201 is fixed at the four corners of the outer wall of the sealing shell 1, and plays a role in positioning and connecting. It provides an installation foundation for the entire fixing mechanism 2, so that the fixing mechanism 2 can be tightly combined with the sealing shell 1. The fixing rod 202 is rotatably connected to the middle part of the inner wall of the fixing plate 201, which enables the fixing rod 202 to be adjusted around the rotation point. By adjusting the angle of the fixing rod 202, the sealing shell 1 can be fixed at a suitable angle according to the actual installation environment and needs, which increases the flexibility of installation. One end of the bolt 203 is rotatably connected to one side of the inner wall of the fixing rod 202, and the other end passes through the fixing ring 204 and is threadedly connected to the nut 205. When the sealing shell 1 needs to be fixed, first adjust the fixing rod 20 2, and then tighten the nut 205 to move the bolt 203 upward in the fixing ring 204. Since the bolt 203 is rotatably connected to the fixing rod 202, the movement of the bolt 203 will drive the fixing rod 202 to rotate around the rotation point with the fixing plate 201, so that the fixing rod 202 is tightly against the installation surface, thereby fastening the sealing shell 1. The connecting rod 206 rotatably connected to the top of the outer wall of the fixing ring 204 has its other end rotatably connected to the top of the inner wall of the fixing plate 201. The connecting rod 206 plays an auxiliary supporting role in the fixing process, enhances the stability of the fixing mechanism 2, prevents the fixing rod 202 from excessive deformation or shaking when subjected to force, and ensures that the sealing shell 1 can be firmly fixed in the installation position.
