Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic box transformers, in particular to a novel photovoltaic box transformer which is easy to install. Background Art

[0002] A photovoltaic box transformer is a device used to convert solar energy into electrical energy. Its main parts include one or more photovoltaic panels, an inverter, and a controller. Photovoltaic panels can be installed on rooftops or other places and convert direct current (DC) into alternating current. The inverter is responsible for converting AC into stable DC for home or commercial use. The controller is able to monitor and control the performance of the entire system to ensure maximum energy utilization and safety; the advantage of this photovoltaic box transformer is that it can work in any weather conditions and does not require any additional maintenance. In addition, it can save a lot of energy and money because it has higher efficiency and lower operating costs than traditional sources of electricity. Therefore, it is a very attractive option for consumers who want to reduce their energy bills and reduce their impact on the environment.

[0003] At present, a Chinese utility model patent application with publication number CN207320648U proposes a new type of photovoltaic box transformer, including a box body and a box door, the box door is movably connected to the box body by hinges, a handle is provided on the side of the box door, and the handle is fixedly connected to the box door by screws. This new type of photovoltaic box transformer, using an electric energy meter, can not only detect the amount of electricity generated by the solar panel in real time, so as to make full use of electricity and calculate the power generation efficiency, but also can measure the amount of electricity transmitted at any time, so as to carry out accurate calculation and power regulation in time, which greatly reduces the work pressure of electricians. At the same time, when the current exceeds the specified value, the fuse melts the fuse with the heat generated by itself, thereby disconnecting the circuit, performing short-circuit and over-current protection on the photovoltaic box transformer, greatly improving the safety of the equipment, and extending its service life. In addition, the power coefficient of the box transformer can be improved through the reactive power compensator, the loss of the transformer and the transmission line can be reduced, the power supply efficiency can be improved, and the power supply environment can be improved.

[0004] However, since photovoltaic box transformers are generally fixed to the ground using bolts or direct welding through connectors, the welding fixation method is inconvenient to operate and special tools must be used for auxiliary installation, which reduces work efficiency. When fixing with bolts, the threaded holes at the connection must always be kept corresponding to each other, and in order to increase stability, the bolts must be tightened for installation, which is more troublesome to operate.

[0032] A photovoltaic box transformer is a device used to convert solar energy into electrical energy. Its main parts include one or more photovoltaic panels, an inverter, and a controller. Photovoltaic panels can be installed on rooftops or other places and convert direct current (DC) into alternating current. The inverter is responsible for converting AC into stable DC for home or commercial use. The controller is able to monitor and control the performance of the entire system to ensure maximum energy utilization and safety; the advantage of this photovoltaic box transformer is that it can work in any weather conditions and does not require any additional maintenance. In addition, it can save a lot of energy and money because it has higher efficiency and lower operating costs than traditional sources of electricity. Therefore, it is a very attractive option for consumers who want to reduce their energy bills and reduce their impact on the environment.

[0033] However, since photovoltaic box transformers are generally fixed to the ground using bolts or direct welding through connectors, the welding fixation method is inconvenient to operate and special tools must be used for auxiliary installation, which reduces work efficiency. When fixing with bolts, the threaded holes at the connection must always be kept corresponding to each other, and in order to increase stability, the bolts must be tightened for installation, which is more troublesome to operate.
