Background technology
Photovoltaic isolating switch is in high-voltage switch electric appliance, to use maximum a kind of switches, as its name suggests, plays buffer action in circuit.Its functional reliability requires high, and the operation on electrical network, power plant and foundation impact are all larger.
After traditional isolating switch is communicated with power supply and external loading (equipment), in the time that electric current is excessive, the load meeting that isolating switch exceedes expection is burned, and causes short circuit, has larger potential safety hazard.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of and eliminated safe hidden trouble, photovoltaic insulation blocking switch assembly simple in structure.
For achieving the above object; the utility model provides following technical scheme: a kind of photovoltaic insulation blocking switch assembly; include Switch main body, be series at the dynamic and static contact of at least two groups, the button in Switch main body and be located at button the moving contact linkage unit between moving contact; wherein one group of dynamic and static contact is power input; another group is power output end; it is characterized in that: described Switch main body is installed in a box body, and the fuse of connecting with the power output end in Switch main body is installed in box body.
Wherein, in Switch main body, be provided with four groups of dynamic and static contacts, each group dynamic/static contact connects by terminals respectively, wherein, first group of dynamic and static contact respectively with terminals A and B UNICOM, second group of dynamic and static contact respectively with terminals C and D UNICOM, the 3rd group of dynamic and static contact respectively with terminals E and F UNICOM, the 4th group of dynamic and static contact is respectively at terminals G and H UNICOM, terminals B is communicated with terminals C, terminals D is communicated with terminals E, and terminals F is communicated with terminals G; Described fuse is located between terminals H and the 4th group of dynamic and static contact.
Adopt technique scheme; by the fuse being communicated with the power output end of Switch main body is set in box body; in the time that curtage exceeds the load that can not bear; operating personnel now cannot detect timely and isolating switch be closed timely, and fuse now can, by circuitry cuts, be implemented protection to whole circuit; prevent the fire causing due to short circuit; eliminate potential safety hazard, also can prevent that isolating switch is impaired, has extended the useful life of isolating switch simultaneously.
The utility model is further set to: the lid that box body includes body for holding Switch main body and fuse and fastens with body, and the installation place that described lid is positioned at fuse is provided with transparence and renovates, and this transparence is renovated with lid and is and is articulated and connected.
Adopt technique scheme, after arranging like this, implemented self effect (occur fusing after) when fuse, operating personnel can open the transparent pivoted cover on box body, fuse is implemented to change the setting of the transparent pivoted cover observation of personnel to fuse that be convenient to operation.
Below in conjunction with accompanying drawing, the utility model is further described.
