Description

Technical Field

[0001] This utility model relates to the field of monitoring and alarm devices, specifically a bus voltage monitoring and alarm device. Background Technology

[0002] Bus voltage transformers are key equipment in power systems used for collecting and distributing electrical energy. Their voltage stability directly affects power supply safety. Monitoring and alarm devices collect parameters such as bus voltage and frequency in real time, and use sensors and intelligent analysis modules to compare the data. When abnormalities such as overvoltage, undervoltage, or excessive fluctuations are detected, an alarm is immediately triggered and uploaded to the monitoring system. This device can provide early warnings of potential hazards such as insulation aging and short circuits, helping maintenance personnel to quickly locate faults, avoid equipment damage and large-scale power outages, and ensure the stable operation of the power system.

[0003] Existing patent number CN221351596U provides a smart substation voltage and current monitoring device, including a digital voltage and current display meter. A housing is fixedly connected to the back surface of the digital voltage and current display meter. The inner cavity of the housing is provided with a monitoring mechanism for real-time monitoring of voltage and current parameters. This application uses the elastic force of a spring to drive the movable block to reset. Then, with the cooperation of the movable block and the conductive block, it can not only fix the wire without the aid of external force, but also achieve waterproof and dustproof effects through the sealing cover. This provides a more stable, fast and reliable connection, thereby relieving the workload of maintenance personnel and extending the service life of the digital voltage and current display meter. It solves the problem that traditional monitoring devices require tools to connect cables, which is not only inconvenient for cable fixing or replacement, but also takes a lot of time during the connection process.

However, this requires the use of special tools when disassembling and assembling the devices, which leads to complicated or time-consuming operation procedures and reduces work efficiency.

[0006] 2. Existing bus voltage monitoring and alarm devices are generally equipped with displays for data visualization. However, since the devices do not have dustproof functions, dust easily accumulates on the screen surface during long-term use. This not only reduces the display clarity but also requires repeated cleaning and maintenance when the device is restarted, failing to meet the usage requirements. Utility Model Content

[0027] Reference Figure 1 , Figure 2 and Figure 3The assembly / disassembly component 2 includes a mounting bracket 201. A limiting seat 202 is located in the center of the mounting bracket 201. A connecting shaft 203 is located inside the limiting seat 202. A knob 204 is located at one end of the connecting shaft 203. A forward thread 205 is provided on one side of the outer surface of the connecting shaft 203, and a reverse thread 206 is provided on the other side. A movable plate 207 is located on the outer surface of the connecting shaft 203 at the location of the forward thread 205. A limiting rod 208 is located on one side of the movable plate 207. A pressing plate 209 is located on the front of the movable plate 207. A sliding groove 2010 is opened on the front of the mounting bracket 201. The limiting rod 208 is fixedly connected to the mounting bracket 201. The movable plate 207 is slidably connected to the outer surface of the limiting rod 208. The movable plate 207 is generally U-shaped.

[0028] Specifically: It facilitates the support and limitation of the moving plate 207 by means of the limiting rod 208, thereby improving the stability of the moving plate 207 during horizontal displacement.
