Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a comprehensive online monitoring device for high-voltage cables. Background Technology

[0002] With the rapid development of electrified rail transit construction and the continuous expansion of its operational scale, the requirements for the stability, reliability, and safety of its power supply system are also constantly increasing. During operation, all primary equipment in the power supply system may experience faults such as short circuits and wire breaks due to external forces, insulation aging, overvoltage, misoperation, and design and manufacturing defects. Currently, planned maintenance remains the primary method for addressing this issue. While this plays a positive role in ensuring the normal operation of equipment, it also exposes some problems. In recent years, online monitoring technology, widely used in the power industry, can accurately reflect the actual operating status of equipment, detect potential equipment hazards in advance, reduce accident losses, improve work efficiency, and provide a basis for the maintenance of rail transit power supply systems.

[0003] A high-frequency pulse current sensor installed on the grounding wire of the cable joint couples couples the partial discharge pulse current signal. A leakage current sensor uses a Rogowski coil to couple the leakage signal of the cable body for synchronous monitoring. A current transformer installed on the grounding lead of the cable joint acquires the current magnitude on the grounding wire. A wireless passive temperature sensor monitors the real-time temperature of the operating cable body. The coupled signal is transmitted to the integrated online cable monitoring device via a coaxial cable. The analog signal is amplified, converted to digital, and then transmitted to the monitoring host. However, in actual use, the high-voltage cable integrated online monitoring device has many internal signal receiving components, such as processors, often concentrated in the same square housing. This results in high internal temperatures during operation, which are difficult to dissipate effectively, easily causing component burnout and short circuits, significantly impacting safety. Utility Model Content

[0004] The purpose of this invention is to provide a comprehensive online monitoring device for high-voltage cables. By incorporating a cavity, infusion pipeline, protection box, micro-liquid pump, and storage tank, cold water can continuously circulate through the serpentine infusion pipeline. This allows for the rapid removal of high-temperature heat from the main body of the online monitoring device, effectively cooling the device and preventing the internal circuit components from burning out. This significantly improves the safety of the device and addresses the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage cable integrated online monitoring device, comprising:

[0006] Main body of the online monitoring device;

[0007] The device includes a cavity located at the bottom of the main body of the online monitoring device. Inside the cavity, a serpentine infusion pipeline is installed. One end of the infusion pipeline extends outside the cavity and is connected to a first connecting pipe, while the other end extends outside the cavity and is connected to a second connecting pipe. A protective box is installed at one bottom end of the main body of the online monitoring device. A miniature liquid pump is installed at one end of the protective box, and a storage tank is installed at the other end. One end of the miniature liquid pump is connected to the storage tank via a pipe, and the other end extends outside the protective box and is connected to the second connecting pipe. The bottom end of the first connecting pipe extends inside the protective box and is connected to the storage tank. A cooling component is installed on the protective box.

[0008] Preferably, the protective box includes a housing located on the bottom side of the main body of the online monitoring device, and a cover is fixedly connected to the bottom opening of the housing by bolts.

[0009] Preferably, the cooling component includes a plurality of grooves provided on the side wall of the housing, and a cooling plate connected to the liquid storage tank is installed inside the groove.

[0010] Preferably, a duct is connected through to both ends of one side of the main body of the online monitoring device, a fan is fixedly connected inside the duct by a bracket, and a second filter is provided at the port of the duct.

[0011] Preferably, the main body of the online monitoring device has multiple heat dissipation slots on one side relative to the air duct, and a first filter screen is installed inside the heat dissipation slots.

[0012] Preferably, one end of the main body of the online monitoring device is provided with a mounting plate, and both ends of the mounting plate are provided with mounting holes.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By setting up structures such as chambers, infusion pipelines, protective boxes, micro liquid pumps, and storage tanks, cold water can continuously circulate through the serpentine infusion pipelines. This allows the high-temperature heat inside the main body of the online monitoring device to be quickly carried away, effectively cooling and dissipating heat from the main body of the online monitoring device. This prevents the internal circuit components from burning out and greatly improves the safety of the device.

[0015] Furthermore, by incorporating a fan, heat dissipation trough, second filter, and first filter, the internal structure of the online monitoring device can be further ventilated, thereby providing additional heat dissipation protection. Attached Figure Description

Based on this, the mounting plate 2 facilitates the fixed installation of the main body 1 of the online monitoring device inside the electrical equipment cabinet.

[0029] A cavity 12 is located at the bottom of the main body 1 of the online monitoring device. Inside the cavity 12, there is a serpentine distribution of infusion tubing 15. One end of the infusion tubing 15 extends outside the cavity 12 and is connected to a first connecting pipe 13. The other end of the infusion tubing 15 extends outside the cavity 12 and is connected to a second connecting pipe 14. A protective box 18 is installed at one end of the bottom side of the main body 1 of the online monitoring device. A micro liquid pump 10 is installed at one end of the interior of the protective box 18, and a liquid storage tank 11 is installed at the other end of the interior of the protective box 18.

The water in the storage tank 11 can be cooled by the cooling plate 17.

Furthermore, the second filter 6 and the first filter 4 can prevent dust and debris from entering the interior. With the cooperation of this structure, the heat dissipation protection function can be further achieved.
