Description

Technical Field

[0001] This utility model relates to the field of cable monitoring equipment, and in particular to an online cable fault monitoring device. Background Technology

[0002] A cable is a bundle of wires used to transmit electrical energy or signals. It consists of one or more conductors and is wrapped with insulating material to prevent short circuits between conductors and contact between conductors and the external environment. Cable faults refer to any problems that occur during the operation of a cable, causing it to fail to transmit electrical energy or signals normally. Cable faults can occur in power cables or communication cables, and they can be caused by a variety of reasons, including physical damage, insulation aging, environmental factors, and installation errors.

[0003] Currently, with the passage of time and the influence of the operating environment, cable insulation materials gradually age, and their insulation performance decreases. At this time, using a partial discharge online monitoring device can promptly detect partial discharge phenomena occurring in the early stages of insulation aging, providing early warning of faults. In existing cable fault online monitoring devices, when the display panel needs stable support, the dust cover can be rotated via a pivot. Since both sides of the dust cover and the main unit have sliders connected by grooves, and one end of each slider is connected to a support rod via a pivot, the dust cover rotates, causing the sliders to rotate and slide along the grooves. Before rotating the dust cover, the insertion rod can be pulled out from both sides of the main unit. Then, the dust cover can be rotated. When the slider in the main unit's groove slides to the position of the insertion rod, the insertion rod is released, and the insertion rod is reset by a compression spring and inserted into the slider. This serves to limit the slider's movement. Furthermore, when the slider cannot move, the existing online monitoring device... When using wired communication for data transmission, online cable fault monitoring devices require cables to connect sensors to data acquisition units, and data acquisition units to backend monitoring systems, to transmit monitoring data. After use, the cables are retracted into the inner wall of the device. However, current online monitoring devices use fixing blocks and limiting rods to secure the cables. Different cable specifications have different thicknesses, while the dimensions and spacing of the fixing blocks and limiting rods are usually fixed. For thinner cables, this may not provide sufficient clamping force, causing the cables to sway at the fixing point. For thicker cables, this may prevent them from being properly installed between the fixing blocks and limiting rods, or may cause excessive compression after installation. Both swaying of thinner cables and excessive compression of thicker cables will adversely affect the cable insulation layer, accelerate the insulation aging process, significantly reduce insulation performance, and lead to leakage and short circuit faults. This shortens the cable's lifespan, increases maintenance costs, and raises the risk of system failure.

[0004] Therefore, it is necessary to provide a new type of online cable fault monitoring device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an online cable fault monitoring device.

[0006] The present invention provides an online cable fault monitoring device, which includes a device body and a switch door. The switch door is hinged to one side wall of the device body by a hinge, and two fixing components are fixedly connected to the inner wall of the switch door.

[0007] The fixing assembly includes a base, a support plate, a driving component, two connecting rods, and two clamping mechanisms. The base is fixedly connected to the inner wall of the door. The support plate is fixedly connected to the top and has placement holes. The driving component is fixedly connected to the top of the support plate, and a driving frame is fixedly connected to the telescopic end of the driving component. One end of each of the two connecting rods is rotatably connected to the inner wall of a through hole in the driving frame via a connecting rod. The end of the connecting rod away from the connecting rod is rotatably connected to the inner wall of a through hole in the support plate. The two clamping mechanisms are rotatably connected to the ends of the two connecting rods away from the driving frame via a rotating shaft.

[0008] Preferably, the clamping mechanism includes a connecting block and a clamping block. The connecting block is rotatably connected to the end of the connecting rod away from the drive frame via a rotating shaft, and a support block is fixedly connected to the end of the connecting block away from the connecting rod. The clamping block is fixedly connected to the inner wall of a through hole opened on the support block.

[0009] Preferably, the driving component is a cylinder, which is fixedly connected to the top of the support plate, and the telescopic end of the cylinder is fixedly connected to the bottom of the drive frame.

[0010] Preferably, a plurality of rubber blocks are provided on one side wall of the clamping block.

[0011] Preferably, a handle is fixedly connected to one side wall of the main body of the device.

[0012] Preferably, the main body of the device and the switch door are both made of polycarbonate material.

[0013] Compared with related technologies, the cable fault online monitoring device provided by this utility model has the following advantages:

[0014] By using the fixed components, when it is necessary to fix the cable used for testing, the cable to be fixed is first placed between two support blocks. Then, the cylinder is activated, which drives the drive frame to move. As the drive frame moves, it drives the connecting rod to move through the connecting block. As the connecting rod moves, it drives the support block and the clamping block on the support block to move towards the cable through the connecting block fixed on its own, and the clamping block fixes the cable. This device reduces the probability of leakage and short circuit faults, shortens the service life of the cable, and reduces maintenance costs and the risk of system failure.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

Figure 3 for Figure 1 The diagram shows the structure of W.

[0022] In the specific implementation process, such as Figure 1As shown, a handle 13 is fixedly connected to one side wall of the main body 1. The switch door 2 is hinged to one side wall of the main body 1. Two fixing components are fixedly connected to the inner wall of the switch door 2. The fixing components include a base 3, a support plate 4, a driving component, two connecting rods 5 and two clamping mechanisms. The base 3 is fixedly connected to the inner wall of the switch door 2. The support plate 4 is fixedly connected to the top and has a placement hole 6. The driving component is fixedly connected to the top of the support plate 4 and has a driving frame 7 fixedly connected to the telescopic end of the driving component. One end of each of the two connecting rods 5 is rotatably connected to the inner wall of the through hole opened on the driving frame 7 through a connecting rod 8. The end of the connecting rod 8 away from the connecting rod 5 is rotatably connected to the inner wall of the through hole opened on the support plate 4. The two clamping mechanisms are rotatably connected to the ends of the two connecting rods 5 away from the driving frame 7 through a rotating shaft.

[0023] It should be noted that both the main body 1 and the switch door 2 are made of polycarbonate material. Polycarbonate is a high-performance thermoplastic engineering plastic. Polycarbonate is a high molecular polymer containing carbonate groups in its molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, aliphatic and aliphatic-aromatic polycarbonates have lower mechanical properties, which limits their application in engineering plastics. At present, only aromatic polycarbonates have been industrialized, and the most common polycarbonate is bisphenol A polycarbonate.

[0025] It should be noted that the driving component is cylinder 12, which is fixedly connected to the top of the support plate 4, and the telescopic end of cylinder 12 is fixedly connected to the bottom of the drive frame 7.

[0026] When it is necessary to fix the cable used for testing, first place the cable to be fixed between the two support blocks 11, then start the cylinder 12. The cylinder 12 drives the drive frame 7 to move. While the drive frame 7 is moving, it will drive the connecting rod 5 to move through the connecting rod 8. While the connecting rod 5 is moving, it will drive the support block 11 and the clamping block 10 set on the support block 11 to move towards the cable through the connecting block 9 fixed on it, and fix the cable through the clamping block 10.

[0027] The working principle of this utility model is as follows: When it is necessary to fix the cable used for testing, the cable to be fixed is first placed between two support blocks 11, and then the cylinder 12 is started. The cylinder 12 drives the drive frame 7 to move. While the drive frame 7 is moving, it will drive the connecting rod 5 to move through the connecting rod 8. While the connecting rod 5 is moving, it will drive the support block 11 and the clamping block 10 set on the support block 11 to move towards the cable through the connecting block 9 fixed on it, and fix the cable through the clamping block 10.
