Description

Technical Field

[0001] This utility model is a busbar connection device for real-time temperature measurement. Background Technology

[0002] In modern industrial and commercial buildings, low-voltage high-density busbar trunking is widely used across various industries due to its superior current-carrying capacity and long service life. Its modular design and highly integrated structure give busbar trunking high safety and reliability in power transmission and distribution systems. However, with the rapid development of semiconductor technology, intelligent monitoring equipment is gradually penetrating the traditional power industry, and the busbar trunking industry is also beginning to see the emergence of intelligent products to meet the needs of real-time monitoring and management of power system operation.

[0003] Existing intelligent monitoring equipment is mainly installed in the plug-in boxes of busbar trunking systems to detect parameters such as current, voltage, and temperature. However, for critical connection points in the busbar trunking system, such as busbar connection points, these devices often lack effective temperature measurement methods. Due to long-term operation, the connection points of busbar trunking are susceptible to increased contact resistance, mechanical fatigue, and environmental factors (such as temperature changes and humidity), leading to localized overheating and affecting the safety and stability of the entire system. Current temperature measurement solutions on the market generally suffer from insufficient measurement accuracy, complex installation, and difficult maintenance, making it difficult to meet the needs of real-time temperature monitoring of connection points. Therefore, how to provide an efficient and accurate temperature measurement solution without affecting the normal operation of the busbar trunking to improve the system's safety and intelligence level has become an urgent problem to be solved in this field. Utility model content:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a busbar connection device for real-time temperature measurement.

[0005] A busbar trunking connection device for real-time temperature measurement includes a connector and a temperature measuring device. The connector is fitted with a bolt, the tail of which extends to the outside of the connecting machine. The temperature measuring device is fitted with a threaded sleeve, which is threadedly connected to the protruding part of the bolt.

[0006] Furthermore, it also includes a wireless controller, which can record the number of the temperature measuring device and its corresponding connector number or location.

[0007] Furthermore, the wireless controller periodically receives data feedback from the temperature measuring device.

[0008] Furthermore, the wireless controller issues an alarm signal to connectors that exceed a preset threshold based on the temperature data from the temperature measuring device.

[0009] Furthermore, the wireless controller includes a storage module for storing historical temperature data from each temperature measuring device to enable trend analysis and fault prediction.

[0010] Furthermore, the temperature measuring device employs passive temperature sensing technology and is powered by thermoelectric materials or an energy harvesting module.

[0011] Furthermore, the temperature measuring device uses a low-power wireless communication protocol for data transmission.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0013] A passive temperature measurement device enables real-time temperature monitoring of busbar trunking connection points, facilitating timely detection of abnormal temperature rises and reducing safety hazards. The device periodically transmits temperature data, allowing the host computer to quickly view and locate potential fault points, reducing manual inspection time and improving maintenance efficiency. The passive temperature measurement device eliminates the need for external power supply, reducing energy consumption and improving system stability and reliability. Directly installed on the connector bolts, the area closest to the conductor's high temperature, it maximizes temperature data acquisition and improves measurement accuracy. The temperature measurement device is installed after the connectors are installed and insulation and tightening torque tests are completed, without affecting the normal installation process of the busbar trunking. The threaded tightening method is simple to operate and has low maintenance costs. After installation, it can be remotely activated wirelessly, and the device immediately begins periodically feeding back temperature information without manual intervention, enhancing the level of intelligent management. Recording the device number and busbar trunking connector number ensures traceability of equipment information, facilitating long-term monitoring and data analysis, and improving the controllability of system operation and maintenance.

[0018] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0019] A busbar trunking connection device for real-time temperature measurement includes a connector 1 and a temperature measuring device 2. The connector 1 is provided with a bolt 3, the tail of which extends out of the connector 1. The temperature measuring device 2 is provided with a threaded sleeve 4, which is threadedly connected to the protruding part of the bolt 3.

[0020] This busbar trunking connection device is used for connection points in high-density busbar systems. A temperature measuring device 2 is installed on bolt 3 of connector 1 to achieve real-time temperature detection. The temperature measuring device 2 utilizes bolt 3 as the temperature conduction medium, ensuring the accuracy of the measurement data. The temperature measuring device 2 is installed externally on bolt 3, avoiding modifications to the main structure of the busbar trunking and facilitating maintenance and replacement.

[0021] Working principle: This real-time temperature measuring connector 1 is a specially developed busbar connection unit. It has the current connection function of the traditional connector 1, and is also equipped with a passive temperature measuring device 2. The bolt 3 of connector 1 is the component closest to the highest temperature point except for the conductor. The temperature measuring module is directly installed on the bolt 3 of connector 1, which can maximize the acquisition of temperature parameters and realize the real-time temperature detection function. Every set time interval, the host will receive the real-time temperature signal of each connector 1 to help quickly view and locate potential fault connection points.

[0022] This device can accurately measure the temperature of busbar trunking connection points, especially the connector 1 area which is prone to temperature rise. This helps to detect potential overheating problems in a timely manner and improves the safety of the busbar system. Meanwhile, the temperature measuring device 2 uses a threaded connection, making installation convenient and not affecting the insulation performance of the busbar trunking.

[0023] In one possible implementation, a wireless controller is also included, which can record the number of the temperature measuring device 2 and the number or location of its corresponding connector 1.

[0024] When the wireless controller is installed in the bus trunking system, it identifies and stores the unique number of each temperature measuring device 2, and establishes a correspondence between it and the number or specific location of the bus trunking connector 1. In this way, during subsequent monitoring, the system can quickly locate the specific connector 1 where an abnormal temperature rise occurs.

[0025] The numbering management function of the wireless controller enables the establishment of a comprehensive busbar temperature monitoring database, improving the accuracy of fault location and reducing the workload of inspections.

[0026] In one possible implementation, the wireless controller periodically receives data feedback from the temperature measuring device 2.

[0027] Temperature measuring device 2 automatically sends current temperature data to the wireless controller at preset time intervals (e.g., 10 seconds, 1 minute, 5 minutes, etc.). The wireless controller receives the data, stores it, and performs real-time analysis. When a temperature measuring device 2 fails to upload data on time or the temperature exceeds the limit, the system can issue an alarm.

[0028] Periodic data collection enables continuous monitoring of busbar connections, ensuring that potential hazards can be detected and addressed in a timely manner.

[0029] In one possible implementation, the wireless controller issues an alarm signal to connector 1 when the temperature exceeds a preset threshold, based on the temperature data from the temperature measuring device 2.

[0030] The wireless controller is set with a temperature threshold (e.g., 80°C). When the temperature of a connector 1 exceeds this threshold, the system will automatically trigger an alarm, including an audible and visual alarm, an SMS reminder, or a remote notification to maintenance personnel.

[0031] This function can improve the safety of the bus trunking system, provide timely warnings of potential faults, and prevent equipment damage or fire hazards caused by excessive temperature.

[0032] In one possible implementation, the wireless controller further includes a storage module for storing historical temperature data of each temperature measuring device 2 for trend analysis and fault prediction.

[0033] The wireless controller can store temperature data from each temperature measuring device 2 for an extended period and analyze temperature change trends. For example, if the temperature of a connector 1 remains high for an extended period but does not exceed the limit, it can be considered a potential hazard, and the system can issue an early warning.

[0034] This feature can be used for predictive maintenance, reducing equipment failure rates, lowering operating costs, and improving the long-term reliability of busbar systems.

[0035] In one possible implementation, the temperature measuring device 2 employs passive temperature sensing technology and is powered by thermoelectric materials or an energy harvesting module, requiring no external power supply.

[0036] The temperature measuring device 2 uses thermoelectric materials or vibration energy harvesting technology to convert heat or mechanical vibration in the environment into electrical energy to maintain the normal operation of the sensor without the need for batteries or external power supply.

[0037] This solution significantly reduces maintenance costs, avoids the hassle of regularly replacing batteries, and improves the reliability and applicability of the temperature measuring device 2.

[0038] In one possible implementation, the temperature measuring device 2 uses a low-power wireless communication protocol for data transmission to reduce energy consumption and improve device lifespan.

[0039] The industrial temperature measurement device 2 adopts low-power wireless communication protocols such as LoRa, BLE (Bluetooth Low Energy), and Zigbee to reduce energy consumption during data transmission and improve the device's battery life.

[0040] Low-power wireless communication technology can reduce the energy consumption of temperature measuring device 2, enabling the device to operate stably for a long time while ensuring the reliability of data transmission.

[0041] Working principle: This real-time temperature measuring connector is a specially developed busbar connection unit. It has the current connection function of a traditional connector and is also equipped with a passive temperature measuring device. The connector bolt is the component closest to the highest temperature point, apart from the conductor. The temperature measuring module is directly installed on the connector bolt to maximize the acquisition of temperature parameters and realize the real-time temperature detection function. At a set interval, the host will receive the real-time temperature signal of each connector to help quickly view and locate potential faulty connection points.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
