Abstract
The invention relates to a photovoltaic assembly main loop protecting method. A controllable switch is arranged between every two assemblies. Each controllable switch comprises an input and an output for connecting assemblies. The switches are simultaneously controlled to be on and off. By means of the method, each assembly can be disconnected through external signals. System maintenance is facilitated. Meanwhile, safety is greatly improved.
Description
Technical field
The present invention relates to solar energy power generating field, particularly a kind of photovoltaic module major loop guard method.
Background technology
Photovoltaic generation is a kind of technology utilizing the photovoltaic effect of interface and luminous energy is directly changed into electric energy.The key element of this technology is solar cell.Solar cell carries out packaging protection after series connection can form large-area solar module, then coordinates the parts such as upper power controller just to define photovoltaic power generation apparatus.
Direct sunlight is converted into direct current by solar photovoltaic assembly, photovoltaic group ganged up direct current conflux case parallel connection access DC power distribution cabinet, inverter direct-flow input end is accessed after confluxing, change direct current into alternating current, inverter ac output incoming transport power distribution cabinet, is directly incorporated into user side through AC power distribution cabinet/AC distribution panel.
Large-area solar module can be formed because solar cell carries out packaging protection after series connection; when there will be solar cell maintenance; need whole solar module out of service; thus reduce the efficiency of generating; simultaneously when solar cell breaking out of fire; other solar cell can be had influence on, have influence on whole solar module, thus whole solar components is damaged.
Summary of the invention
The object of the invention is to provide one to facilitate solar cell to keep in repair, and when preventing solar cell breaking out of fire, affects a kind of method of whole solar module simultaneously.
In order to solve the problems of the technologies described above, present invention employs following methods:
The guard method of a kind of photovoltaic module major loop, all install gate-controlled switch between every 2 block assemblies, gate-controlled switch has the input and output for coupling assembling, control switch conducting simultaneously and cut-out.
Described gate-controlled switch adopts mechanical type to control.
Described gate-controlled switch adopts semiconductor-type to control.
Described gate-controlled switch adopts radio communication type to control.
Gate-controlled switch has the input and output for coupling assembling, has control switch conducting and cut-out simultaneously.Concrete implementation method is as follows: between every 2 block assemblies, all can install gate-controlled switch, can realize disconnecting each block assembly by external signal, be convenient to system maintenance and maintenance; If breaking out of fire, can adopt outside centralized control, as applied radio signal, galvanization etc., allow and disconnect assembly series loop, allow the voltage of assembly be not more than the voltage of assembly self, so fail safe will improve greatly.
Beneficial effect of the present invention: 1, can realize disconnecting each block assembly by external signal, be convenient to system maintenance and maintenance; 2, fail safe will improve greatly.
embodiment
The guard method of a kind of photovoltaic module major loop, all install gate-controlled switch between every 2 block assemblies, gate-controlled switch has the input and output for coupling assembling, control switch conducting simultaneously and cut-out.
Described gate-controlled switch adopts radio communication type to control.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
