Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable splicing technology, specifically to a cable splicing device for a photovoltaic power plant. Background Technology
[0002] In photovoltaic power plants, cable splicing devices are key components for connecting different cable segments and realizing power transmission and distribution. Their design must consider factors such as electrical performance, mechanical strength, environmental adaptability, and ease of installation and maintenance. They are typically made of highly conductive materials to ensure efficient power transmission. The connector body design must meet specific electrical parameter requirements, such as rated voltage and current. High-performance insulating materials are used to wrap the connector body to prevent current leakage and short circuits, ensuring electrical safety. This includes waterproof, dustproof, and corrosion-resistant sealing measures, as well as necessary mechanical protection structures to ensure long-term stable operation of the device in harsh environments. These devices are used to securely install the splicing device onto the cable, ensuring the stability and reliability of the connection. By optimizing the design and material selection of the connector body, low-resistance, low-loss power transmission is achieved. The connection between the photovoltaic array and the inverter transmits the DC power generated by the photovoltaic modules to the inverter for conversion. In photovoltaic power plants, cable splicing devices are crucial components for ensuring smooth power transmission and distribution.
[0003] According to Chinese Patent Publication No. CN221961378U, a cable connector belongs to the field of cable splicing technology. It includes a housing, an inner liner installed inside the housing, the inner liner being cylindrical, and a clamping screw installed outside the housing, the end of the clamping screw abutting against the outer surface of the inner liner. A pressure relief groove is formed on the outer surface of the inner liner. This utility model provides a cable connector that increases the thickness of the inner liner, improving its adaptability to high currents.
[0004] In the above solution, an inner liner is installed inside the housing. The inner liner is cylindrical, and a clamping screw is installed outside the housing. The end of the clamping screw abuts against the outer surface of the inner liner. A pressure relief groove is opened on the outer surface of the inner liner. This results in the following disadvantages: the existing docking device can only fix one cable at a time and then manually dock it, which reduces docking efficiency, reduces flexibility, and is not conducive to long-term use. It can only fix one size cable at a time, which is cumbersome, increases the labor intensity of workers, reduces work efficiency, and reduces practicality. Therefore, there is an urgent need for a cable docking device for photovoltaic power plants to solve the above problems. Utility Model Content
