Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a pole-mounted switch with an image monitoring device. Background Technology

[0002] With the continuous improvement of the automation level of smart grids and distribution networks, higher requirements are placed on the monitoring of the operating status and fault diagnosis of power equipment. Traditional 10kV pole-mounted switches (such as circuit breakers and load switches) mainly undertake the functions of line switching control and protection. They are usually installed on power poles in urban distribution networks or remote mountainous areas. Their locations are scattered and the environment is complex, making it difficult to achieve real-time monitoring of their operating status and the surrounding environment.

[0003] In recent years, with the development of video surveillance and remote communication technologies, the application of image acquisition devices in power systems has become a trend. However, on long-distance transmission lines, especially high-voltage lines in remote mountainous areas, the lack of reliable low-voltage power supplies for image acquisition equipment limits its application on pole-mounted switches. Traditional methods often rely on solar power or laying low-voltage cables separately, but these methods suffer from high costs, difficult maintenance, and significant susceptibility to weather conditions. Utility Model Content

The secondary low-voltage power supply provides the obtained power energy to the load through the voltage stabilizing circuit.

[0007] As an optimized solution of this utility model, the voltage regulator circuit includes a rectifier and an LDO regulator. The rectifier rectifies the AC power of the secondary low-voltage power supply into DC power, and the LDO regulator obtains 12V DC power.

[0008] As an optimized solution of this utility model, the camera device includes a power management unit, a gimbal control unit, a control processing unit, and a camera. The power management unit is responsible for converting the power energy provided by the high-voltage capacitor power supply into a power supply suitable for the gimbal control unit, the control processing unit, and the camera.

[0013] This utility model has the following positive effects: 1) This utility model integrates a capacitor-powered power supply and a camera into a circuit breaker. By selecting a suitable installation method, real-time monitoring of the surrounding environment can be achieved. The capacitor-powered video acquisition device is very suitable for long-distance mountain lines where there are only high-voltage lines and the image acquisition device cannot be directly powered. It can also be used around the clock, without the disadvantage of not being able to use it normally during long periods of rainy weather.

[0014] 2) This utility model utilizes the high-voltage bus voltage to draw power through a high-voltage capacitor. After being isolated and stepped down by a transformer and processed by a voltage stabilization circuit, a stable low-voltage DC power supply is obtained to drive the camera and its control module. This capacitor-based power extraction method has advantages such as simple structure, small size, no need for additional wiring, and all-weather operation, making it very suitable for use on high-voltage lines without mains power supply. The pole-mounted switch with integrated image monitoring function can not only realize visual monitoring of the line operation status, but also be extended to various application scenarios such as ground environment monitoring, forest fire prevention, illegal building identification, and natural disaster early warning, greatly improving the intelligence level and operation and maintenance efficiency of the power distribution system.
