Embodiment Construction
[0018] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0019] like figure 1 As shown: the photovoltaic combiner box of the present invention includes a box body, and the box body includes a box bottom 1 and an upper cover 2 matched with the box bottom 1, wherein the box body is made of aluminum, which can be conveniently Processing and casting; at the same time, compared with the existing photovoltaic combiner box, it can reduce the volume of the box and reduce the occupied area during use. Generally, the upper cover 2 is hinged on the bottom 1 of the box.
[0020] like figure 2 and image 3 As shown: in order to monitor and control the working mode of the solar cell panel when the box body is in use, a main control board is provided in the box body of the present invention, and the main control board includes a plurality of IGBT devices 3 and is connected to the IGBT device 3. A current detection circuit 4 th...

The invention relates to a junction box, in particular to a mini-type intelligent photovoltaic junction box, belonging to the technical field of photovoltaic junction boxes. Through the technical scheme of the invention, the mini-type intelligent photovoltaic junction box comprises a box body consisting of a box bottom and an upper cover, wherein the box body is made of aluminum. According to the mini-type intelligent photovoltaic junction box disclosed by the invention, the box body is made of the aluminum so as to have small weight and reduced volume, and is also used as a heat-radiating fin of an IGBT (insulated gate bipolar transistor) device so as to have good heat-dispersion performance; a main control board is arranged in the box body, each IGBT device and a current detection circuit of the main control board form a detection control branch circuit, and a junction box controller on the main control board is used for controlling the state of the IGBT devices according to a current value inputted by the current detection circuit so as to reach a purpose of effectively monitoring a solar cell board; and the mini-type intelligent photovoltaic junction box disclosed by the invention has the advantages of capability of saving machining and using cost, high automation degree, convenience for machining and manufacturing, safety and reliability.
Description
technical field [0001] The invention relates to a combiner box, in particular to a miniature intelligent photovoltaic combiner box, which belongs to the technical field of photovoltaic combiner boxes. Background technique [0002] With the development of society, the demand for energy is becoming increasingly tense. China is very rich in solar energy resources. Accelerating the construction of photovoltaic power plants is not only in line with my country's national conditions, but will also more effectively promote the transformation of my country's economic structure and the optimization of energy structure. In the solar photovoltaic power generation system, in order to reduce the connection between the solar photovoltaic cell array and the inverter, a combiner box is required. [0003] Current combiner boxes are made of steel plates or engineering plastics, and generally consist of the following main parts: box body, DC circuit breaker, lightning protection device, monito...
