Whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of three parts: solar panels (components), controllers and inverters. As a green new energy, solar photovoltaic power generation is convenient to obtain resources, safe and pollution-free, and is an inevitable trend in the development of new energy. While building new energy development, it is also necessary to consider how to unify the intelligent platform management. The system management equipment layer is inseparable from primary equipment, data collectors, control terminals, remote communication equipment, etc., and photovoltaic power generation also needs to be used with corresponding circuit breakers. Photovoltaic circuit breakers are one of the key equipment in photovoltaic power generation systems. In the traditional installation process of the circuit breaker, the staff first needs to carefully align the wires and insert them into the connection slot of the circuit breaker. After that, the wires need to be fixed to the connection slot with screws, and tightened several times during the installation process, which not only increases the complexity of the installation, but also greatly prolongs the time required for installation, resulting in low work efficiency. Summary of the invention

At this time, the first spring will be compressed until the L-shaped top frame is no longer in contact with the top block. The top block and the paddle plate will move in the direction of the inside of the installation groove under the action of the second spring until the top block contacts the wire and clamps the wire to complete the connection of the wire. At this time, the top block and the other end of the L-shaped top frame are abutted.

At this time, the first spring is no longer under force, and then the L-shaped top frame will move toward the top block under the action of the spring until the L-shaped top frame is in contact with the top block. The top block can be kept in the initial position for the next use. The device is relatively convenient to connect during actual use and does not require the use of screws to fix the wires.
