Description

Technical Field

[0002] Substations are crucial infrastructure in the power system, responsible for voltage transformation, power distribution, and control regulation in the process of transmitting electrical energy from power plants to user terminals. The joints of substation equipment are the core nodes for realizing electrical connection and energy transmission in the power system, and their operating status directly affects the safety of the power grid and the reliability of power supply. Among them, temperature monitoring of equipment joints is one of the important means to prevent safety accidents such as equipment overheating and fire.

However, due to factors such as equipment vibration, changes in ambient temperature, and material aging, joints may become loose or fall off, leading to poor contact, increased resistance, and potentially causing overheating or even fires. Meanwhile, temperature monitoring of substation equipment joints mainly relies on manual inspections or periodic infrared thermometer checks. However, these methods have limitations in terms of real-time performance and efficiency, making it difficult to detect joint abnormalities in a timely manner.

[0025] The real-time monitoring unit 1 includes a temperature measuring component 101 and an alarm component 102. The temperature measuring component 101 includes a fixing frame 1011, an extrusion plate 1012 disposed on the front of the fixing frame 1011, an RFID temperature measuring tag 1013 fixedly connected to the back of the extrusion plate 1012, and a microcontroller 1014 fixedly connected to the right side of the front of the fixing frame 1011.

[0030] In this embodiment, the alarm component 102 includes a fixing plate 1021, an alarm 1022 fixedly connected to the upper front end of the fixing plate 1021, and a signal processing module 1023 fixedly connected to the lower front end of the fixing plate 1021.

[0031] The output of the RFID temperature measurement tag 1013 is connected to the input of the microcontroller 1014, and the output of the microcontroller 1014 is connected to the input of the alarm 1022, the signal processing module 1023, and the indicator light 203.

[0032] The signal processing module 1023 integrates a multimodal sensor interface, an edge computing module, a Wi-Fi communication module, a safety protection component, and a power management subsystem, and transmits data to staff in real time via Wi-Fi.

[0033] like Figure 2 and 4As shown, the mounting bracket 1011 provides an installation platform for other components, ensuring the stability and reliability of the temperature measuring assembly 101. The extrusion plate 1012 is used to fix the RFID temperature measuring tag 1013 and can make tight contact with the connector through the reset force, improving the temperature measurement accuracy.

The mounting plate 1021 provides an installation platform for the alarm 1022 and signal processing module 1023, ensuring their stability and reliability. When the microcontroller 1014 determines that the connector is overheating, the alarm 1022 can sound an alarm to remind staff to handle it in time.

[0034] Example 3

[0035] Reference Figure 3 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] In this embodiment, the clamping assembly 204 includes a support block 2041 movably connected to the upper and lower ends of the front of the fixing frame 1011 via bearings, a fixing block 2042 disposed on the front of the support block 2041, and a limiting post 2043 fixedly connected to the front of the support block 2041. The front end of the limiting post 2043 extends into the inner cavity of the fixing block 2042 and is slidably connected to its inner cavity.

[0037] The clamping assembly 204 also includes an anti-detachment piece 2044 fixedly connected to the front end of the limiting post 2043, and a stainless steel spring 2045 fixedly connected to the front side of the anti-detachment piece 2044. The front end of the stainless steel spring 2045 is fixedly connected to the front side of the inner cavity of the fixing block 2042.

[0038] like Figure 3 and 4As shown, the support block 2041 is movably connected to the fixed frame 1011 via a bearing and can be used to adjust the angle of the clamping assembly 204. The fixed block 2042 works in conjunction with the limiting post 2043 to support the connecting block 201 and ensure the stability and reliability of the clamping assembly 204. The anti-detachment plate 2044 can prevent the limiting post 2043 from coming out of the inner cavity of the fixed block 2042. The stainless steel spring 2045 is used to provide clamping force, thereby improving the stability of the connector insertion.

[0039] In use, firstly, the fixing bracket 1011 is fixed to the surface of the connector plate using bolts. The shape of the fixing bracket 1011 and the number of connecting blocks 201 can be increased or decreased according to the actual situation. The connector cable is then moved through the through groove 202 into the interior of the connecting block 201. Next, the connector can be plugged into the interface. At this time, the return force of the stainless steel spring 2045, in conjunction with the connecting block 201, drives the compression plate 1012 to compress the connector, thereby improving the stability of the connector connection. During equipment operation, the RFID temperature measuring tag 1013 can monitor the connector temperature in real time. When the joint temperature is abnormal and reaches the preset value of the microcontroller 1014, the microcontroller 1014 can activate the alarm 1022 and the corresponding indicator light 203, and transmit the signal to the signal processing module 1023. The signal processing module 1023 transmits the signal to the staff's mobile phone or computer. At this time, the alarm 1022 can sound an alarm to alert nearby staff, and the indicator light 203 will light up to instruct the staff. After arriving at the scene, the staff can directly observe the lit indicator light 203 to find the location of the temperature abnormality and perform maintenance.
