Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a power metering device. Background Art

[0002] In the power system, power metering equipment, as a core component, undertakes the important task of accurately measuring and recording power consumption. There are various types of equipment, including but not limited to watt-hour meters, current transformers, voltage transformers, power factor meters, active power meters and reactive power meters, etc. These equipment are of great significance to the daily operation, maintenance and strategy optimization of the power system. By collecting power data in real time and accurately in each period, they provide a solid data foundation for efficient management and decision-making of the system.

[0003] However, in the actual deployment and operation of power metering equipment, a series of technical challenges and safety risks have been encountered, which are specifically manifested in the following aspects:

[0004] Safety protection issues under the influence of external environment: The equipment is vulnerable to the impact of natural phenomena such as lightning, which may cause damage to the lightning protection components and threaten the safe operation of the entire metering system.

[0005] Insufficient convenience in installation and maintenance: The current installation method of power metering equipment in the box is complicated and difficult to achieve quick disassembly and assembly, which undoubtedly increases the difficulty and time cost of maintenance operations.

[0006] Challenges in electrical connection stability: Wire connections between devices are easily affected by external forces, such as being pulled and falling off or getting entangled with each other. This will not only interfere with the normal working state of the equipment, but may also induce electrical failures and increase safety risks.

[0055] When the external controller (not shown) is embedded with a weather detection device, when the weather is clear, the second drive motor 1002 is turned on, and the second drive motor 1002 drives the first bevel gear 1003 to rotate, and then drives the screw rod 1005 to rotate through the second bevel gear 1004, so that the movable block 1009 moves upward through the guidance of the screw rod 1005 and the second slide bar 1007, and the movable block 1009 drives the anti-collision frame 1010 to rise, so as to protect the radar equipment on the top of the power metering body 5. When it is raining or cloudy, the anti-collision frame 1010 is similarly lowered to the lowest point and mounted on the outside of the outer shell 2, so as to prevent the staff from carelessly touching the equipment on rainy days, thereby reducing the occurrence of safety accidents.

[0056] When the inner shell 3 to which the power meter body 5 is fixedly connected is subjected to a downward force, the bottom of the inner shell 3 will transmit the force to the second sliders 1104 on both sides through the fixing rod 1105, and then the second sliders 1104 slide to both sides inside the fixing frame 1101, and the second spring 1103 buffers the downward force of the inner shell 3, thereby improving the protection of the power meter body 5.

[0057] When it is necessary to check the power metering body 5 and before opening the cabinet door 201, the staff presses the insulating plate 1204 inward, and the insulating plate 1204 will slide inward along the second sliding groove 1202 through the second connecting plate 1203 until the electric test pen 1206 contacts the cabinet door 201. The electric test pen 1206 will detect whether the cabinet door 201 is energized, thereby ensuring the life safety of the staff. When the electric test pen 1206 completes the detection, the insulating plate 1204 is released, and the insulating plate 1204 can be reset by the elastic force of the third spring 1205, thereby always preparing the cabinet door 201 for the next detection.

[0058] It can be seen from the above description that compared with the prior art, the beneficial effects brought about by the embodiments of the present invention are: the innovative clamping mechanism realizes the rapid and stable installation and disassembly of the power metering body, which significantly improves the work efficiency and maintenance convenience. The design of the fixing mechanism effectively prevents the device plug from falling off due to external force, while keeping the wires neat and orderly. The locking mechanism simplifies the replacement process of the dustproof net, reduces the difficulty of maintenance, and enhances the cleanliness and operating efficiency of the equipment. The anti-collision mechanism automatically adjusts the protection state according to weather changes, protects the radar equipment from damage, and reduces safety accidents. The shock-absorbing mechanism provides buffering protection for the equipment and extends its service life. The anti-electric shock mechanism ensures the safety of the operator and enhances the overall safety of the equipment. The present invention has multiple protection functions and shows significant advantages in improving work efficiency, ensuring safety, maintenance convenience and equipment stability.

[0059] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
