Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-voltage switchgear fault detection, specifically an online fault detection terminal that can be installed quickly. Background Technology
[0002] During the use of high-voltage switchgear, it is necessary to use a temperature detection system to detect overheating of the internal contacts and aging of cable joints. At this time, an RF temperature sensor can be installed on the busbar of the high-voltage switchgear for temperature detection. When the internal temperature of the high-voltage switchgear exceeds the limit, the RF temperature sensor will transmit the signal to the cloud and alert the workers.
[0003] Currently, the common method for installing radio frequency temperature sensors is to use screws for fixing. Screw fixing provides greater stability, but during the calibration and disassembly / replacement of the temperature sensor, the high-voltage cabinet needs to be powered off for electrical safety, which increases maintenance costs. In addition, the screws in the high-voltage cabinet may corrode in humid environments, making them difficult to remove. Therefore, to address these issues, a fault online detection terminal that can be installed quickly is proposed. Utility Model Content
[0004] To overcome the shortcomings of existing technologies and avoid the problem of troublesome temperature sensor replacement and installation, this utility model proposes an online fault detection terminal that can be installed quickly.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an online fault detection terminal that can be quickly installed, comprising: The cabinet has a busbar fixedly installed on the top of its inner wall, a detection component inside the busbar, an installation component inside the detection component, and a grounding bar fixedly connected to the bottom of its inner wall. The mounting assembly includes a groove on the surface of the detection assembly, a fixing rod fixedly connected inside the groove, a sliding block slidably connected to the surface of the fixing rod, a damping block fixedly connected inside the sliding block, and a friction block fixedly connected to the front end of the sliding block.
[0006] Preferably, the detection component includes a hollow block snapped into the busbar, an RF sensor is disposed inside the hollow block, a protective block is fixedly connected to the surface of the RF sensor, and protrusions are fixedly connected to both the upper and lower ends of the hollow block.
[0007] Preferably, a battery is installed inside the hollow block, and the battery is electrically connected to the radio frequency sensor. The battery can power the radio frequency sensor, so the radio frequency sensor does not need to be wired for power supply, which makes it easy to install.
[0008] Preferably, the end of the protective block away from the radio frequency sensor is attached to the inner wall of the hollow block, and the protective block can shield and protect the battery inside the hollow block.
[0009] Preferably, the damping block is slidably connected to the surface of the fixed rod, and the friction between the damping block and the fixed rod makes the sliding block move slowly and stably. The friction block is adapted to fit against the surface of the busbar, and the position of the hollow block is limited by the friction between the friction block and the busbar.
[0010] Preferably, a magnetic block is fixedly connected inside the sliding block, a rotating rod is rotatably connected to the front end of the sliding block, a baffle is fixedly connected to the end of the rotating rod away from the sliding block, a pull rod is fixedly connected to the front side of the baffle away from the sliding block, a connecting block is fixedly connected to the rear side of the baffle away from the sliding block, and a magnetic block is fixedly connected inside the protrusion.
[0011] Preferably, the adjacent ends of the first magnetic block and the second magnetic block are opposite magnetic poles, and the baffle is located between the first magnetic block and the second magnetic block. The baffle blocks the space between the first magnetic block and the second magnetic block to avoid excessive mutual attraction between the first magnetic block and the second magnetic block, thereby facilitating the disassembly and replacement of the hollow block.
[0012] Preferably, the grounding terminal of the radio frequency sensor is fixedly connected to the surface of the ground bar, which improves the safety of the radio frequency sensor during use.
[0013] The advantages of this utility model are: This invention involves inserting a hollow block into the inside of the busbar. The attraction between magnetic block one and magnetic block two causes the sliding block and friction block to abut against the surface of the busbar, thus installing the hollow block inside the busbar. At this point, a radio frequency sensor is used to detect high temperatures inside the cabinet. This installation process is simple and does not require powering off the high-voltage cabinet. The operator can rotate a baffle to block between magnetic block one and magnetic block two, which reduces the attraction between them, allowing the operator to directly remove the hollow block and disassemble the radio frequency sensor.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail. This application discloses an online fault detection terminal that can be installed quickly. (Refer to...) Figure 1 A fault online detection terminal that can be quickly installed includes: Cabinet 1, a busbar 2 is fixedly installed on the top of the inner wall of cabinet 1, a detection component 3 is installed inside the busbar 2, an installation component 4 is installed inside the detection component 3, and a ground busbar 5 is fixedly connected to the bottom of the inner wall of cabinet 1. Reference Figure 3 and 5 The mounting component 4 includes a groove 41 on the surface of the detection component 3. A fixing rod 42 is fixedly connected inside the groove 41. A sliding block 431 is slidably connected to the surface of the fixing rod 42. A damping block 432 is fixedly connected inside the sliding block 431. A friction block 433 is fixedly connected to the front end of the sliding block 431. The damping block 432 is slidably connected to the surface of the fixing rod 42. The friction between the damping block 432 and the fixing rod 42 makes the sliding block 431 move slowly and stably. The friction block 433 fits and adheres to the surface of the busbar 2. The position of the hollow block 31 is limited by the friction between the friction block 433 and the busbar 2.
[0019] Reference Figures 2-3 The detection component 3 includes a hollow block 31 that is snapped into the inside of the busbar 2. An RF sensor 32 is installed inside the hollow block 31. The grounding terminal of the RF sensor 32 is fixedly connected to the surface of the grounding busbar 5, which improves the safety of the RF sensor 32 during use. A protective block 33 is fixedly connected to the surface of the RF sensor 32. Protrusions 34 are fixedly connected to both the upper and lower ends of the hollow block 31. A battery is installed inside the hollow block 31. The battery and the RF sensor 32 are electrically connected. The battery can power the RF sensor 32. At this time, the RF sensor 32 does not need to be wired for power supply, which facilitates installation. The end of the protective block 33 away from the RF sensor 32 is attached to the inner wall of the hollow block 31. The protective block 33 can shield and protect the battery inside the hollow block 31.
[0020] Reference Figure 5 A magnetic block 44 is fixedly connected inside the sliding block 431. A rotating rod 451 is rotatably connected to the front end of the sliding block 431. A baffle 452 is fixedly connected to the end of the rotating rod 451 away from the sliding block 431. A pull rod 453 is fixedly connected to the front side of the end of the baffle 452 away from the sliding block 431. A connecting block 454 is fixedly connected to the rear side of the end of the baffle 452 away from the sliding block 431. A magnetic block 46 is fixedly connected inside the protrusion 34. The near ends of the magnetic blocks 44 and 46 are opposite magnetic poles. The baffle 452 is located between the magnetic blocks 44 and 46. The baffle 452 blocks the magnetic blocks 44 and 46 to prevent the mutual attraction between the magnetic blocks 44 and 46 from being too strong, thus facilitating the disassembly and replacement of the hollow block 31.
[0021] When the operator needs to install the RF sensor 32 inside the busbar 2, first, snap the RF sensor 32 and the protection block 33 into the hollow block 31, then snap the hollow block 31 into the busbar 2. The operator can then pull the lever 453, causing the lever 453 to rotate the baffle 452 and the rotating rod 451. The baffle 452 rotates away from the first magnetic block 44 until it reaches the front side of the sliding block 431. This causes the first magnetic block 44 and the second magnetic block 46 to attract each other. At this time, the first magnetic block 44 will drive the fixedly connected sliding block 431 to move accordingly. When the sliding block 431 moves, it will drive the damping block 432 to slide on the surface of the fixed rod 42. Under the damping effect of the damping block 432, the sliding block 431 moves slowly and stably until the sliding block 431 drives the friction block 433 to move and abut against the surface of the busbar 2. At this time, the sliding block 431 is limited by the static friction between the friction block 433 and the busbar 2, which in turn limits the protrusion 34 to the inside of the busbar 2. At this time, the radio frequency sensor 32 is quickly installed inside the busbar 2. After installation, the operator can connect the grounding terminal of the radio frequency sensor 32 to the surface of the ground bar 5.
[0022] When it is necessary to calibrate or disassemble and replace the RF sensor 32, the baffle 452 can be pushed directly, causing the baffle 452 to drive the rotating rod 451 to rotate against the friction between it and the sliding block 431. At this time, the baffle 452 will rotate between the first magnetic block 44 and the second magnetic block 46, thereby reducing the attraction between the first magnetic block 44 and the second magnetic block 46. At this time, the friction block 433 is not subjected to external force and the static friction between it and the busbar 2 is reduced. Therefore, the operator can directly pull the hollow block 31 outward to remove it from the inside of the busbar 2, and then reinstall the calibrated or replaced hollow block 31 inside the cabinet 1.
[0023] Then, the radio frequency sensor 32 can detect the internal temperature of the cabinet 1. When an abnormally high temperature occurs inside the cabinet 1, the radio frequency sensor 32 receives the signal and uploads the signal to the cloud through the transmission module to alert the workers, thereby avoiding safety hazards.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
