Description

Technical Field

[0001] The invention relates to the field of technical power transmission line monitoring, and in particular to an on-site power supply device for video monitoring of power transmission lines. Background Art

[0002] Overhead transmission lines are an important part of the power system. They bear the heavy responsibility of power transmission, regulation and distribution. Once a failure occurs, it will directly affect the safe and stable operation of the power grid. As overhead lines are exposed to the wild environment for a long time, they are greatly affected by extreme natural weather and man-made external forces, which leads to frequent accidents in some overhead transmission lines. The use of manual or drone inspections cannot solve the problem of real-time control of transmission lines. To this end, cameras are installed on transmission towers, and remote video monitoring technology is used to monitor overhead transmission lines with frequent failures in real time, so as to promptly discover and deal with potential safety hazards and avoid major transmission line failures.

[0003] Since the operation of video monitoring equipment requires a large amount of electricity, it is necessary to provide stable and uninterrupted power supply for video monitoring equipment. The existing power supply methods generally include solar power supply, access to the mains, energy storage battery power supply, etc., and the power supply stability is relatively low. Summary of the invention

[0004] The purpose of the present invention is to provide a local power supply device for video monitoring of power transmission lines to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the present invention provides an on-site power supply device for video monitoring of transmission lines, including a snap-on current transformer and a battery. The snap-on current transformer is sleeved on the outside of the transmission line, and the snap-on current transformer is electrically connected to the battery fixed on the transmission tower and used to power the video monitoring equipment through a rectifier.

[0006] Preferably, the snap-on open-and-close current transformer includes an insulating elastic open-and-close shell, a half-type mounting shell snapped onto the inner side of the insulating elastic open-and-close shell, and two arc iron cores snapped onto the inside of the half-type mounting shell. The two arc iron cores form a magnetic ring, and a wire threading hole is provided in the center of the magnetic ring for threading a power transmission line. A secondary coil is wound around one of the arc iron cores, and the secondary coil is electrically connected to the battery via a lead wire.

[0007] Preferably, the insulating elastic retractable housing comprises an insulating elastic housing, a mounting opening is provided on the insulating elastic housing, and a buckle is provided at the mounting opening;

[0008] The inner side of the insulating elastic shell is in close contact with the outer side of the half-type installation shell. The inner side of the half-type installation shell is provided with installation grooves arranged in a ring array. The installation grooves are clamped with the magnetic conductive ring.

[0009] Preferably, the half-type mounting shell is composed of two symmetrically arranged half shells;

[0010] A compression positioning block is symmetrically fixed on the inner side of the insulating elastic shell, a plug-in convex head is integrally formed on the outer side of the compression positioning block, and a plug-in hole for plugging with the plug-in convex head is opened on the insulating elastic shell;

[0011] A positioning hole is provided in the middle of the clamping positioning block, and positioning convex heads are integrally formed at the relative positions of the two half shells, and the positioning convex heads are inserted into the positioning hole.

[0012] Preferably, the half-type installation shell is a cylindrical structure with an installation opening at one end, a half-type front end cover is clamped at the installation opening, and through holes are provided on both the half-type front end cover and the half-type installation shell, and the through holes are coaxially arranged with the threading hole.

[0013] Preferably, a plurality of elastic wire-pressing barrels are clamped in a circumferential array on the half-type mounting shell and around the through hole, and the plurality of elastic wire-pressing barrels form a wire-clamping channel, which is clamped to the power transmission line.

[0014] Preferably, the insulating elastic shell, the half-type installation shell, the half-type front end cover and the elastic wire crimping barrel are all made of PVC.

[0015] Therefore, the present invention adopts the above-mentioned local power supply device for video monitoring of power transmission lines, which has the following beneficial effects:

[0016] 1. Safe and reliable electrical isolation: Insulating elastic shell: The insulating elastic shell made of PVC material can effectively prevent current leakage and ensure the safety of operators;

[0017] Electrical isolation design: The connection between the snap-on current transformer and the battery is achieved through lead wires, avoiding the risk of direct contact with high-voltage wires;

[0018] 2. Convenient and fast installation and maintenance: snap-on opening and closing design: The insulated elastic opening and closing shell allows for easy opening and closing without power outage, making installation and maintenance easier;

[0019] Half-type installation shell: It is composed of two symmetrically arranged half shells. When installing, you only need to pass the power transmission wire through the threading hole and then close the shell, which simplifies the installation steps;

[0020] Elastic wire crimping barrel: Multiple elastic wire crimping barrels arranged around the through hole position form a wire clamping channel, which not only fixes the transmission wire but also protects it from the influence of the external environment;

[0021] 3. Compact and durable structure: From the outer shell to the internal structure, modular design is adopted, and each component is closely matched, which reduces the space occupation and is suitable for installation in a narrow transmission tower environment;

[0022] Material selection: All components are made of PVC material with good weather resistance, excellent anti-aging and corrosion resistance, and can operate stably for a long time under harsh weather conditions;

[0023] 4. Flexible and adaptable: By replacing the elastic wire barrel, it can be used for transmission wires of different diameters and types, with strong flexibility;

[0024] 5. Environmental protection and energy saving: Low power consumption design: Through efficient electromagnetic induction technology and reasonable circuit design, energy loss is minimized and energy consumption is reduced;

[0025] Utilization of renewable energy: Utilize existing power resources on transmission lines without laying additional cables or relying on other energy sources, thus achieving efficient use of resources.
