Problems solved by technology

Since the diode will generate a higher temperature during operation, as the temperature of the diode continues to rise, the resistance in the diode will continue to increase, causing the diode to generate more heat, thus wasting more power resources into the vicious circle
In order to ensure better heat dissipation of the photovoltaic junction box, the method of increasing the volume of the conductive sheet installation cavity in the photovoltaic junction box is generally adopted, thereby increasing the thickness and volume of the entire photovoltaic junction box. More importantly, it is difficult to use this method Achieve good cooling effect

Abstract

The invention discloses a photovoltaic terminal box, comprising a base, a box cover and a seal ring, wherein the base and the box cover carry out vertical extrusion and horizontal extrusion on the seal ring; terminal block components are arranged in the base and each terminal block component comprises a terminal main body, a wire clamp, a bus bar clamp and two diode clamps; a strut member is connected with a radiating component; an end face of each terminal main body is inserted into slots at two sides of the strut member and each terminal main body is riveted with the strut member; and the radiating components of the adjacent terminal block components are connected by heat conducting insulators and the radiating components and diodes are connected mutually by heat conducting insulators. The photovoltaic terminal box has high sealing property and a short terminal main body, and can be used for cooling and quick heat conduction.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a photovoltaic junction box applied in a photovoltaic power generation system. Background technique [0002] In the electrical connection technology of solar power generation systems, solar photovoltaic junction boxes are usually used to realize the electrical connection between photovoltaic modules and inverters. Considering that the application of the junction box is usually an outdoor environment, it is an important consideration in the design of the junction box to prevent rainwater and other media from penetrating into the junction box and affecting the internal electrical connection. In the sealing structure of the existing photovoltaic junction box, the upper and lower covers of the junction box are connected by bayonets or fasteners, and the seal is sealed by squeezing the rubber sealing ring up and down inside the upper and lower covers, which is inconvenient...
