Smart photovoltaic lightning protection combiner box

Abstract

The invention discloses a smart photovoltaic lightning protection combiner box. The box includes a box body. An insulation board is connected to the front face of the inner side of the box body. A module box is fixedly connected to the front face of the insulation board. Springs are fixedly connected to two sides of the inner wall of the module box. A clamp board is fixedly connected to one side away from the inner wall side of the module box of each spring. A filtering box is fixedly connected to one side away from a slide chute of each slide block. A filter screen is arranged in an inner cavity of each filtering box. A drying box is fixedly connected to the bottom of the inner side of the box body. A heat dissipation box is fixedly connected to each of two sides of the bottom of the inner wall of the box body. According to the invention, through cooperative use of the box body, connection boards, necks, box doors and sealing gaskets, a problem of box opening inconvenience during combiner box maintenance is solved. Through cooperative use of the insulation boards, the module box, the springs, the clamp boards and clamp holes, a problem of dismounting convenience of inner parts ofthe combiner box is solved. Through cooperative use of the drying box and a drying bag, a problem of large humidity in the combiner box is solved.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to an intelligent photovoltaic lightning protection combiner box. Background technique [0002] In the photovoltaic power generation system, the combiner box is a wiring device to ensure the orderly connection and confluence function of photovoltaic modules. This device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and when the photovoltaic system fails, it can reduce the scope of power outage. The combiner box It means that the user can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic series, and then connect several photovoltaic series in parallel to the photovoltaic combiner box. After converging in the photovoltaic combiner box, through the controller, DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet are used together ...
