[0050] Example 1

[0051] See also Figure 1-8 , the present invention provides the following technical solutions:

[0052] An intelligent monitoring and early warning device for an ultra-high voltage power transmission ring main unit, comprising:

[0053] Lower housing 1;

[0054] The upper shell 2 is slidably connected to the outer surface of the lower shell 1, and a base 3 is provided at the lower end of the lower shell 1;

[0055] The sealing ring 14 is provided on the inner surface of the upper shell 2. The inner surface of the lower shell 1 is provided with a temperature sensor 26, a current sensor 27, a voltage sensor 28 and an audible and visual alarm 29;

[0056] A plurality of convex seats 16 are fixedly connected to the inner surface of the upper shell 2, and a plurality of concave seats 15 are fixedly connected to the inner surface of the lower shell 1;

[0057] The mounting mechanism is provided in the lower housing 1 to achieve the function of mounting and fixing the lower housing 1 and the upper housing 2; and

[0058] The clamping mechanism is arranged in the base 3 to clamp and fix the lower shell 1.

[0059] In a specific embodiment of the present invention, the lower shell 1 accommodates the basic structure of the core monitoring element, provides mechanical support and electromagnetic shielding environment, the upper shell 2 covers the lower shell 1 to form a closed space, and the sliding connection realizes rapid opening and closing, which is convenient for equipment maintenance. The base 3 supports the entire device and connects to the ring network cabinet body to transfer mechanical loads. The sealing ring 14 fills the joint between the upper shell 2 and the lower shell 1 to prevent dust and moisture from invading. The temperature sensor 26 monitors the internal temperature of the ring network cabinet in real time and triggers an early warning when the data is abnormal. The current sensor 27 detects the line current value and generates a fault signal when overcurrent occurs. The voltage sensor 28 collects bus voltage data and identifies voltage fluctuations or surges. The sound and light alarm 29 receives the sensor signal and issues a sound and light alarm to remind on-site personnel. 16 is fixed to the upper shell 2, and cooperates with the concave seat 15 to achieve pre-positioning between the shells. At the same time, the concave seat 15 is fixed to the lower shell 1, guiding the sliding trajectory of the convex seat 16 to prevent the shells from being misplaced. The installation mechanism operation space is provided by the opening of the installation groove 42, which is located at the bottom of the lower shell 1 at an easy-to-operate position. The movable rod 19 is guided to move linearly according to the opened movable groove 17 to limit its lateral offset. At the same time, it is convenient to open the extrusion groove 18. According to the extrusion groove 18, the linear motion of the movable rod 19 is converted into the locking force of the two fixed blocks 21. The external operating force is transmitted through the movable rod 19 to push the two fixed blocks 21 into the interior of the two fixed grooves 20, and the movable rod 19 is connected according to the fixed rotating seat 39. The rotating seat 39 can be manually operated to rotate for installation or removal. At the same time, tools such as screwdrivers can also be operated to achieve labor-saving rotational drive. The two fixing grooves 20 are used to accommodate and limit the two fixing blocks 21. At the same time, the two fixing blocks 21 are inserted into the inside of the two fixing grooves 20 to complete the fixation between the convex seat 16 and the concave seat 15, and prevent the upper shell 2 from separating from the lower shell 1. The sliding shell 22 constrains the movement path of the push seat 23 to ensure vertical linear movement. The push seat 23 is squeezed downward by the active rod 19 to transmit pressure to the extrusion seat 24, and the extrusion seat 24 presses the upper surface of the fixed block 21 to increase the friction between it and the fixed groove 20. According to the second spring 25, a rebound force is provided when the lock is released, and the push seat 23 is automatically reset to slide, which supports the two sliding fixed blocks 21. The function of limiting is that when the bidirectional screw rod 30 is rotated, the two nuts 32 are driven to move synchronously in opposite directions to achieve symmetrical clamping. At the same time, the nut 32 converts the rotational motion of the bidirectional screw rod 30 into linear motion, pushing the clamping block 34 to move. An operating interface for manually rotating the bidirectional screw rod 30 is provided according to the fixed handle 31. The clamping groove 33 is located at the junction of the lower shell 1 and the base 3 to accommodate the clamping block 34 to form an interlock. When the clamping block 34 is inserted into the clamping groove 33, the relative displacement of the lower shell 1 and the base 3 is limited. The limiting rod 35 is provided to pass through the nut 32 and be fixed to the inside of the base 3, thereby constraining the radial displacement of the nut 32. At the same time, the limiting seat 36 cooperates with the limiting rod 35 to eliminate the gap vibration when the nut 32 moves.It plays the role of limiting support for the sliding nut 32. When the device is started, the system is powered on and initialized, and each component enters the standby state. It completes self-test calibration according to the temperature sensor 26, current sensor 27, and voltage sensor 28, and enters the monitoring state. During the real-time monitoring stage, the temperature sensor 26 continuously collects the internal temperature data of the ring network cabinet, the current sensor 27 detects the current value of the transmission line in real time, and the voltage sensor 28 measures the bus voltage fluctuation. When any sensor detects an abnormal parameter, such as temperature exceeding the limit, current overload, and abnormal voltage fluctuation, the corresponding judgment node is triggered. At the same time, the temperature is abnormal → a temperature abnormality signal is generated, the current is abnormal → a current abnormality signal is generated, and the voltage is abnormal → a voltage abnormality signal is generated. All abnormal signals are converged to the processor, and then the sound and light alarm 29 is executed synchronously, the red LED flashes at a high frequency and the buzzer alarm sounds, and the fault code is uploaded through the 4G module. On-site response: the operation and maintenance personnel locate the fault according to the sound and light alarm Equipment, remote response: The monitoring center analyzes the fault code and generates a maintenance work order. According to the intelligent monitoring and early warning device installed in the ring network cabinet, the various parameters of the ring network cabinet are monitored in real time, and an early warning signal can be issued in time when the monitoring result is abnormal. It solves the problem of strong electromagnetic vibration generated during the operation of the ultra-high voltage ring network cabinet, and the existing screw fixing is easy to loosen, resulting in sensor displacement or falling off. At the same time, it can be applied to the line environment of ultra-high voltage transmission, avoiding the occurrence of safety accidents during use, while improving the working efficiency of the ring network cabinet and ensuring the detection of various parameters inside the ring network cabinet. It needs to be explained that the specific type of temperature sensor 26, current sensor 27, voltage sensor 28 and sound and light alarm 29 is selected by relevant technical personnel familiar with this field, and the above temperature sensor 26, current sensor 27, voltage sensor 28 and sound and light alarm 29 are all existing technologies, and this solution will not be repeated.

At this time, the outer surface of the movable rod 19 and the two fixed blocks 21 are in a cross shape with the inner surface of the movable groove 17, and the length is extended and retracted according to the elastic force of the second spring 25. Under the action of force, the extrusion seat 24 is pushed to slide downward, thereby pushing the two fixed blocks 21 to slide into the inside of the two fixed grooves 20 respectively, completing the installation and fixation between the lower shell 1 and the upper shell 2, and then rotating the handle 31 to drive the bidirectional screw rod 30 to rotate, and the two nuts 32 move in opposite directions along the limit rod 35 to push the clamping block 3 4 is inserted into the snap-fitting groove 33 of the lower shell 1 and the base 3, and the limiting seat 36 eliminates the movement clearance of the nut 32 to complete the rigid locking. Then, the base 3 is installed inside the ring network cabinet. The telescopic seat 11 is pushed outward according to the first spring 10, thereby pushing the extrusion pad 13 to squeeze the sliding seat 5. Then, the sliding seat 5 is pulled to slide along the inside of the sliding groove 4. At the same time, the limiting plate 38 slides and limits in the limiting groove 37, and the sliding block 6 is rotated to adjust the pitch angle of the mounting block 7 so that it is aligned with the mounting hole of the ring network cabinet. The device is installed inside the ring network cabinet. The temperature inside the cabinet is monitored according to the set temperature sensor 26, and the current sensor 27 collects the line current value. At the same time, the set voltage sensor 28 measures the bus voltage. When the detected value exceeds the set threshold, the early warning is triggered, so that the processor sends a command to the sound and light alarm 29, and the sound and light alarm 29 starts flashing red light and buzzing.
