Abstract

The invention relates to the technical field of photovoltaic protection circuit breakers, in particular to a pluggable photovoltaic protection circuit breaker. In order to solve the problems that on-site secondary wiring of an existing photovoltaic protection circuit breaker is tedious and errors are prone to occurring, the technical scheme includes that the photovoltaic protection circuit breaker comprises a middle cover, an opening and closing indicator, a release and a base, a face cover is fixed to the middle cover through a bolt, a motor is fixed to the interior of the middle cover through a bolt, and a cam is fixed to the output end of the motor; the cam is eccentrically and rotationally connected with a connecting rod, the base is fixed in the middle cover, and the base is provided with an arc extinguishing system, a contact system, an electromagnetic system, a current transformer, a zero sequence transformer, a temperature sensor, a handle, a transmission part and a traction rod. According to the invention, data of a plurality of photovoltaic grid-connected special protection switches can be connected, collected and uploaded, the structure is compact, installation and use are convenient, the size of a distribution box body is reduced in application, wiring is simplified, the construction cost can be greatly reduced, and intelligent remote management of grid-connected point protection switches is realized.

Description

technical field [0001] The invention relates to the technical field of photovoltaic protection circuit breakers, in particular to a pluggable photovoltaic protection circuit breaker. Background technique [0002] As a green new energy, solar photovoltaic and other power generation is easy to obtain resources, and it is safe and pollution-free. It is an inevitable trend of new energy development. While building new energy development, it is also necessary to consider how to unify intelligent platform management. The system management equipment layer is inseparable from primary equipment, data collectors, control terminals, remote communication equipment, etc., and the existing photovoltaic protection circuit breakers are in On-site secondary wiring is cumbersome and prone to errors. To this end, we propose a pluggable photovoltaic protection circuit breaker. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a pluggable photovoltaic prote...
