Description

Technical Field

[0001] This application relates to the field of temperature monitoring technology, specifically to a device for real-time monitoring of temperature-sensing current test terminals. Background Technology

[0002] In substations, secondary current circuits within terminal boxes, control cabinets, and protection panels require connection via test terminal blocks. Vibrations from the opening and closing of circuit breakers in the control cabinets and enclosures, as well as construction vibrations, can cause current terminals to loosen, increasing contact resistance and leading to abnormal heating. Furthermore, oxidation, dust, and temperature drops during operation can also cause excessive contact resistance and heating. If abnormal defects caused by current circuit heating are not addressed promptly, they can result in terminal block burnout, open current circuits, malfunctions of protection devices, false load tripping, and even fires, jeopardizing the stable operation of the power system and impacting electricity supply for production and daily life. During routine maintenance of relay protection and automation systems, it has been found that loose wiring and intermediate connecting pieces in current test terminal blocks have a high probability of causing open current circuits. Recently, several cases have been discovered where loose wiring or poor contact in intermediate connecting pieces has caused heating and damaged cables and terminals. Both the operation and maintenance department and the control center require regular infrared temperature measurements of current terminal blocks, placing significant pressure on maintenance and repair personnel.

[0005] Preferably, the infrared dot matrix temperature sensor has a 16×4 dot matrix. The relative position of the infrared dot matrix temperature sensor and the terminal block is adjusted so that the width of the temperature matrix completely covers the width of the terminal block, and the length direction of the temperature matrix coincides with the extension direction of the terminal block.

[0006] Preferably, the outer periphery of the emitting part of the infrared dot matrix sensor is provided with an M18 thread and an L-shaped mounting bracket is provided on the outer periphery of the emitting part.

Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." "Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0015] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0016] Example 1 like Figures 1 to 2 As shown, this application provides a real-time monitoring device for temperature-sensing current test terminals, including: a display terminal 1 and several infrared dot matrix temperature sensors 2 electrically connected to the display terminal 1, wherein the display terminal 1 is provided with a wireless communication module that can wirelessly communicate with a cloud server. The display terminal 1 and the mobile terminal connected to the cloud server are equipped with a temperature display system. The terminal block image is displayed on the screen of the display terminal 1 through the temperature display system. The temperature matrix coordinates of each infrared dot matrix temperature sensor 2 correspond one-to-one with the position coordinates on the terminal block image. Different colors are used to mark the temperature status of each coordinate position of the terminal block.

[0017] This application uses an infrared dot matrix temperature sensor 2 to cover all positions of the terminal block, and displays the terminal block temperature in real time through the temperature display system of the display terminal 1. It also provides timely warnings through a wireless transmission module, which greatly alleviates equipment hazards and personnel pressure. It achieves visualized status monitoring of current terminals. Operators can communicate with the cloud server through mobile terminals to realize real-time monitoring and automated control of the temperature of the current circuit terminal blocks. This not only effectively relieves the workload of operation and maintenance personnel in regularly inspecting the terminal blocks with infrared temperature measurement, but also accurately clears potential hazards in current terminal blocks, eliminates monitoring blind spots, avoids open circuit risks, and achieves high-quality operation and maintenance.

[0018] Specifically, such as Figure 2 As shown, the infrared dot matrix temperature sensor 2 has a 16×4 dot matrix. The relative position of the infrared dot matrix temperature sensor 2 and the terminal block is adjusted so that the width of the temperature matrix completely covers the width of the terminal block, and the length direction of the temperature matrix coincides with the extension direction of the terminal block.

[0019] Specifically, such as Figure 2 As shown, the infrared dot matrix temperature sensor 2 has an M18 thread on the outer periphery of its emitting part and an L-shaped mounting bracket on the outer periphery of its emitting part, which facilitates the installation of the infrared dot matrix temperature sensor 2.

[0020] Specifically, the temperature display system has a normal display window on one side of the terminal block image, which displays the real-time temperature of each position coordinate of the terminal block. The system also displays areas where the temperature reaches or exceeds the threshold T-limit in red and areas where the temperature is less than the threshold T-limit in green on the terminal block image, so that operators can observe the alarm area in a timely manner.

[0021] Specifically, when the temperature at any position on the terminal block exceeds the threshold T-limit, the temperature display system sends an alarm via the wireless communication module. Operators can receive the alarm forwarded by the cloud server via a mobile terminal. The threshold T-limit is a preset temperature threshold.

[0022] Preferably, other colors can be used to further distinguish areas at different temperatures.

[0023] Specifically, the temperature display system supports coordinate picking and contour picking functions, as follows: When you click on any position in the terminal block image with the mouse, the temperature display system pops up a window to display the position coordinates and real-time temperature of the corresponding position. When you double-click any position on the terminal block image with the mouse, the temperature display system pops up a window to display the information of the alarm zone closest to the corresponding position. The alarm zone is the terminal block location area where the real-time temperature of all location coordinates within the area reaches or exceeds the threshold T-limit. The alarm zone information includes the area outline coordinates, peak position coordinates, and peak temperature.

[0024] The coordinate picking and contour picking functions help operators obtain single-point temperature information and contour temperature information in a timely manner, thus speeding up the troubleshooting process.

[0025] Preferably, the peak position coordinates and peak temperature are the position coordinates and corresponding temperature data of the highest temperature.

[0026] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
