Description
Technical field
The present invention relates to a kind of fuse tube seat, relate in particular to a kind of solar photovoltaic generation system fuse tube seat.
Background technology
Along with the quick sustainable growth of World Economics, the shortage of the energy has become the key factor of restriction future development.Meanwhile, global warming and the energy safety of supply have become the common Vital Strategic Problems of paying close attention in countries in the world.At this under the new situation, Devoting Major Efforts To Developing utilizes regenerative resource to be not only the inexorable trend of world energy sources development, is also the inevitable choice of Chinese energy strategy.Moreover China's new forms of energy are widely distributed, according to preliminary resource assessment, China's Renewable Energy Resources has a high potential, especially aspect solar energy resources.Therefore; it is an important behave of China's economic development later to the exploitation of solar energy resources; it is for the strong guarantee of providing of energy shortage problem is provided in China's sustained economic development; simultaneously also for China environmental protection provides strong support; the exploitation of solar energy resources are applicable to China's new road toward industrialization requirement, embody the harmony development of man and nature.Wherein, utilizing solar panel generating is many one of utilizing solar energy resources to develop.
Solar panel is a kind of equipment that utilizes solar power generation, it is, by solar panel, solar energy is converted into electric energy, then the power delivery by terminal box, cable-assembly, controller and inverter, solar panel being transformed, can be for the energy of people's daily life or work thereby effectively convert solar energy into AC load, DC load and storage battery.At present, due to along with the significantly improving of solar panel technology, the reduction of cost, photoelectric conversion efficiency is also highly improved, and makes to utilize solar panel to generate electricity and has market application foreground widely.
Wherein, for ensureing the normal work of whole solar photovoltaic generation system, correspondingly, in solar photovoltaic generation system, be provided with that to melt disconnected device be very necessary, this is because the solar panel of solar photovoltaic generation system is subject under the impact of external factor in the conversion process of electric energy at solar energy, very easily in the conversion process of electric energy, produce the phenomenon of transshipping at solar energy, the phenomenon of this overload causes damage very easily to load equipment and solar panel itself, therefore, melt the application of disconnected device in solar photovoltaic generation system and become more and more extensive.
As everyone knows, the specification of melting disconnected device being applied in solar photovoltaic generation system is all very huge (being the numerous disconnected unit that melt that are provided with that melt on disconnected device), and cost is also very expensive, just, owing to melting disconnected device cost costliness, generally can only be applied in powerful solar photovoltaic generation system therefore make to melt disconnected device; And in low power solar photovoltaic generation system, use this to melt disconnected device and can cause some to melt disconnected unit in non-working condition, correspondingly increase the input cost of this low power solar photovoltaic generation system, and increased the weight of investor's burden.Meanwhile, melt disconnected device and do not there is water resistance, generally can only be arranged in the operational environment of waterproof, thereby limited the scope of application of melting disconnected device.Moreover, melting the disconnected cartridge fuse of device and the way of contact of power connection end is: an end face of cartridge fuse contacts at one and is fixed on power connection end melting on disconnected device body, the other end of cartridge fuse contacts at one can melt on power connection end of sliding extension on disconnected device body, thereby by the sliding extension of power connection end, the both ends of the surface of cartridge fuse is contacted between two power connection end.When under the environment in external shock, the way of contact of existing cartridge fuse and power connection end very easily makes cartridge fuse depart from the correct contact position of power connection end, thereby make the contact position of cartridge fuse and power connection end produce dislocation, have influence on the one hand cartridge fuse and the reliability that power connection end contacts, make on the other hand the anti-seismic performance extreme difference between cartridge fuse and power connection end.
Therefore, be necessary to provide a kind of solar photovoltaic generation system fuse tube seat to overcome above-mentioned defect.
