Combiner box being convenient for wiring and good in sealing performance

Abstract

The invention discloses a combiner box being convenient for wiring and good in sealing performance. The combiner box includes a box body, a box door is hinged to the front side of the box body, and awave-shaped first sealing strip is fixedly arranged at the edge of the front side of the box body, and the edge of the back side of the box door is fixedly provided with a wave-shaped second sealing strip, and the first sealing strip and the second sealing strip are matched with each other. According to the invention, through a second transverse rod and under the action of a second spring, a pressing block is pressed to clamp the clamping block in the groove, and the box door is fastened, the box door can be stable and can be opened by the working personnel conveniently, so that the convenience for the working personnel to check or connect the circuits is guaranteed; and the first sealing strip and the second sealing strip are arranged to be wave-shaped, so that the box body and the box door are more tightly closed, rainwater is prevented from entering the box body, and the service life of the electric appliance elements in the box body is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a combiner box which is convenient for wiring and has good sealing performance. 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. The device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the scope of power outage when the photovoltaic system fails. Then connect several photovoltaic series in parallel to the photovoltaic combiner box. After converging in the photovoltaic combiner box, the controller, DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet are used together to form a complete system. Photovoltaic power generation system to achieve grid connection with the mains. [0003] Because the combiner box is installed ...
