[0002] Grid-connected inverters are generally divided into photovoltaic power generation grid-connected inverters, wind power grid-connected inverters, power equipment power generation grid-connected inverters and other power generation equipment power generation grid-connected inverters. In the system of a large-scale photovoltaic power station, many parallel photovoltaic strings are connected to the DC input end of the same centralized inverter, and then converted into alternating current and output from the output end. At present, the plugs connected to the output end are usually connected by friction fit. The plug is easy to loosen and come off, and the current output terminals are directly charged, so it is easy to cause safety hazards

Abstract

The invention discloses grid-connected inverter equipment. The grid-connected inverter equipment comprises a power connection machine body fixedly arranged in the bottom end plane of an inverter machine body, and a plug body in fit connection with the power connection machine body; an inserting-connecting cavity is formed in the bottom end plane of the power connection machine body; a telescopic cavity is formed in the upper side inner wall of the inserting-connecting cavity; a power connection block is mounted in the telescopic cavity in a sliding and matched manner; a jacking spring is mounted in the telescopic cavity on the upper side of the power connection block in a jacking and matched manner; a first rack part is fixedly arranged on the left side end plane of the power connection block; a through hole is formed in the left side inner wall of the telescopic cavity; a transmission gear is arranged in the through hole in a rotational matching manner, wherein the right side end of the transmission gear is meshed with the first rack part; a lifting cavity is formed in the left side inner wall of the through hole; a lifting block is mounted in the lifting cavity in a sliding matchmanner; a second rack part, meshed with the transmission gear, is fixedly arranged on the right side end plane of the lifting block; and a driving motor is arranged in the bottom end plane of the lifting block.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to grid-connected inverter equipment. Background technique [0002] Grid-connected inverters are generally divided into photovoltaic power generation grid-connected inverters, wind power grid-connected inverters, power equipment power generation grid-connected inverters and other power generation equipment power generation grid-connected inverters. In the system of a large-scale photovoltaic power station, many parallel photovoltaic strings are connected to the DC input end of the same centralized inverter, and then converted into alternating current and output from the output end. At present, the plugs connected to the output end are usually connected by friction fit. The plug is prone to loosening and disengagement, and the current output terminals are all directly charged, so potential safety hazards are likely to occur. Contents of the invention [0003] The object of the prese...
