Abstract

The invention discloses a single-pipe welding jig for a three-phase photovoltaic grid-connected inverter. The single-pipe welding jig comprises a base plate, a movable plate of which one end is arranged on the base plate in a rotatable manner, a plurality of supporting columns arranged on the base plate, elastic components arranged at the upper ends of the supporting columns in a sleeving manner, single-pipe protection sleeves which are arranged at the upper ends of the supporting columns and are in contact with the elastic components, and a groove which is formed in the movable plate and corresponds to the single-pipe protection sleeves, wherein a locking device is arranged between the other end of the movable plate and the base plate. Due to arrangement of the base plate and the movable plate, the supporting columns and the single-pipe protection sleeves are arranged on the base plate, single pipes are arranged on the single-pipe protection sleeves, and the movable plate and the base plate are locked, so that uniform welding and mounting of the single pipes can be realized; by virtue of the arrangement of the elastic components, the height positions of the single pipes on the single-pipe protection sleeves are consistent; the welding precision is improved.

Description

technical field [0001] The invention relates to the technical field of single-tube welding, and more specifically, the invention relates to a single-tube welding jig for a three-phase photovoltaic grid-connected inverter. Background technique [0002] At present, most of the domestic and foreign power grids are three-phase four-wire power supply mode, and the three-phase photovoltaic grid-connected inverter is developed based on this power supply mode to convert DC power into AC power and merge it into the national grid. Electric conversion equipment. The core component of the three-phase photovoltaic grid-connected inverter is the main power board, and the inverter module is the core component in the main power board, which plays the role of converting direct current into alternating current; most of the existing inverter modules are It is composed of multiple single tubes (that is, IGBT tubes), and the installation position, installation accuracy and heat dissipation effe...
