Description

Technical Field

[0001] The present invention is a busbar passive automatic temperature monitoring system. Background Art

[0002] In the electrical field, heat monitoring is an important data source for equipment operation and maintenance, which can effectively reflect the operating status and health condition of equipment. With the wide application of modern power equipment, various measuring instruments are integrated into the electrical system to provide a large amount of real-time data, thus supporting operation and maintenance and management. However, existing temperature monitoring devices generally have certain limitations.

[0003] Currently, more than 95% of the temperature monitoring devices on the market need to be separately powered on, or must be in direct contact with the core live components. This design has obvious safety hazards and installation difficulties in a complex and changeable electrical system. First of all, the need for independent power supply increases the complexity of power wiring and may bring additional maintenance costs. Secondly, the monitoring method of direct contact with live components has a high electrical safety risk, especially in a high-voltage power system, which may cause short circuits, discharges and even personal safety accidents.

[0004] In addition, in practical applications, electrical equipment needs to run stably for a long time, and has extremely high requirements for the reliability of power supply. However, traditional temperature monitoring devices are often limited by problems such as power supply interruption and unstable signal transmission, and cannot ensure continuous and reliable collection of key data. Therefore, the market urgently needs a heat monitoring system that is easy to install, does not require additional power supply, and does not increase potential risk points of the system, so as to improve the safety and reliability of monitoring. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art and provide a busbar passive automatic temperature monitoring system.

[0006] A busbar passive automatic temperature monitoring system includes a plurality of temperature sensors, an activator, and a control system. The temperature sensors are used to sense the temperature of each node of the busbar, the control system is used to process the signals transmitted by the temperature sensors, and the activator is used to activate the temperature sensors to make them signal-connected to the control system.

[0007] Furthermore, the control system includes a hollow background, a human-machine interaction device, and an intermediate acquisition device that are signal-connected. The relay acquisition device is used to summarize the data signals of each temperature sensor. The human-machine interaction platform is used to display information or for personnel to control the system. The hollow background is used to number each activated temperature sensor or perform data analysis.

[0008] Furthermore, the hollow background is provided with an alarm module. When the temperature exceeds the threshold, the alarm module sends an alarm signal and displays it on the human-machine interaction device.

[0009] Furthermore, each node of the busbar trunking is a bolt on the busbar trunking connector.

[0010] Furthermore, a screw sleeve is provided at the bottom of the temperature sensor, and the tail of the bolt on the connector is exposed outside, and the screw sleeve is threadedly connected to the tail of the bolt.

[0011] Furthermore, the temperature sensor includes a semiconductor, a base, and a radiator, and both ends of the semiconductor are respectively connected to the base and the radiator.

[0012] Furthermore, the radiator is a fin radiator.

[0013] Beneficial effects: Compared with the prior art, the present invention realizes passive operation through the thermoelectric power generation technology and combines the wireless data transmission technology to realize the real-time monitoring and remote management of the temperature of the busbar trunking. The temperature sensors of the system are installed on the bolts of the busbar trunking connector and are self-powered by the semiconductor thermoelectric generation elements, without the need for additional wiring or external power supply, thereby reducing the installation and operation and maintenance costs.

[0014] The core working process of the system is as follows: When the busbar trunking is running, the temperature of its connecting bolts gradually rises, forming a temperature difference with the ambient temperature. The semiconductor element of the temperature sensor generates a small amount of electric energy through this temperature difference, and then drives the signal transmitting component to transmit temperature data to the superior data acquisition device. Each sensor is activated through a handheld activator after installation and is automatically assigned a unique ID in the system background to ensure the accurate matching of data.

[0015] The data acquisition adopts a multi-level architecture. The relay acquisition device is responsible for summarizing the data of multiple sensors and transmitting it to the hollow background through methods such as LoRa, Zigbee, or cellular network. The human-computer interaction device provides real-time data display and supports the user to control the system through the interface. When the temperature exceeds the set safety threshold, the alarm module will trigger an alarm message, which is displayed on the HMI interface and can notify the maintenance personnel through the remote platform.

[0016] In addition, in order to improve the system adaptability, the sensor also supports the expansion of the NTC thermocouple temperature measurement wire harness, so that a single main sensor can be expanded to a temperature measurement range of 6 m in diameter, meeting the requirements of busbar trunking systems of different scales.

[0017] The system adopts the "plug and play" mode. After installation, no additional maintenance is required, and only the radiator needs to be cleaned regularly to ensure the stability of thermoelectric power generation. The replacement time of a single sensor does not exceed 3 minutes, greatly improving the maintenance efficiency. Description of the Drawings

Specific implementation manners

[0024] To deepen the understanding of the present invention, the present invention will be further described in detail below in combination with embodiments and drawings. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0025] A busbar trunking passive automatic temperature monitoring system includes a plurality of temperature sensors 4, an activator 5, and a control system. The temperature sensors 4 are used to sense the temperature of each node of the busbar trunking. The control system is used to process the signals transmitted by the temperature sensors 4. The activator 5 is used to activate the temperature sensors 4 so that they are signal-connected to the control system.

[0026] In this actual example, the control system includes a hollow background 1, a human-computer interaction device 2, and an intermediate acquisition device 3 that are signal-connected. The relay acquisition device is used to aggregate the data signals of each temperature sensor 4. The human-computer interaction platform is used to display information or for personnel to control the system. The hollow background 1 is used to number or perform data analysis on each activated temperature sensor 4.

[0027] In this actual example, the hollow background 1 is provided with an alarm module. When the temperature exceeds the threshold, the alarm module sends an alarm signal and displays it on the human-computer interaction device 2.

[0028] In this actual example, each node of the busbar trunking is a bolt 11 on the busbar trunking connector 10.

[0029] In this actual example, the bottom of the temperature sensor 4 is provided with a screw sleeve 9. The tail of the bolt 11 on the connector 10 is exposed outside, and the screw sleeve 9 is threadedly connected to the tail of the bolt 11.

[0030] In this actual example, the temperature sensor 4 includes a semiconductor 7, a base 8, and a radiator 6. The two ends of the semiconductor 7 are respectively connected to the base 8 and the radiator 6.

[0031] In this factual example, the radiator 6 described is a fin radiator 6.

[0032] In the above solution, the passive automatic temperature monitoring system of this busway realizes passive operation through thermoelectric power generation technology, and combines wireless data transmission technology to achieve real-time monitoring and remote management of the temperature of the busway. The temperature sensor 4 of the system is installed on the bolt 11 of the busway connector 10 and is self-powered by the semiconductor 7 thermoelectric power generation element, without the need for additional wiring or external power supply, thereby reducing the installation and operation and maintenance costs.

[0033] The core working process of the system is as follows: When the busway is operating, the temperature of its connection bolt 11 gradually rises, forming a temperature difference with the ambient temperature. The semiconductor 7 element of the temperature sensor 4 generates a small amount of electric energy through this temperature difference, and then drives the signal transmitting component to periodically transmit temperature data to the superior data acquisition device. Each sensor is activated through a handheld activator 5 after installation, and a unique ID is automatically assigned in the system background to ensure accurate data matching.

[0034] After the sensor layout is completed, the built-in battery pack can be silent for several years and can start working once it is awakened. The sensor silent wake-up can be operated through a handheld palm computer or a drone. The palm computer first matches the trunk line position in the HMI system, and then performs barcode scanning or radio frequency signal wake-up, and simultaneously matches the accurate position of the sensor in the entire system topology routing, completing the data matching and device wake-up tasks at one time.

[0035] Data acquisition adopts a multi-level architecture. The relay acquisition device is responsible for summarizing the data of multiple sensors and transmitting it to the hollow background 1 through methods such as LoRa, Zigbee, or cellular networks. The human-computer interaction device 2 provides real-time data display and supports users to control the system through the interface. When the temperature exceeds the set safety threshold, the alarm module will trigger an alarm message, which is displayed on the HMI interface and can notify the maintenance personnel through the remote platform.

[0036] In addition, in order to improve the system adaptability, the sensor also supports the extension of the NTC thermocouple temperature measurement wire harness, so that a single main sensor can be extended to a temperature measurement range of 6 m in diameter, meeting the requirements of busway systems of different scales.

[0037] The system adopts a "plug and play" mode. After installation, no additional maintenance is required, and only the radiator 6 needs to be cleaned regularly to ensure the stability of thermoelectric power generation. The replacement time of a single sensor does not exceed 3 minutes, greatly improving the maintenance efficiency.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
