The power distribution equipment of photovoltaic plant and power network is connected, its main function is as the boundary between photovoltaic plant and power network, for low
Grid-connected photovoltaic plant is pressed, grid-connected cabinet can be with house ornamentation with reference to metering and some defencive functions, grid-connected cabinet, as light
The general export of overhead utility is necessarily present in photovoltaic system；The grid-connection cabinet of generator is exactly that one of built-in breaker is " common " high
Compress switch cabinet, because it connects generator system and network system, is provided with complete grid-connected protection device, plays generator simultaneously
Net acts on, and is referred to as " grid-connection cabinet ", and the particular point of the cabinet is exactly that the protection installed is different with other outlet switch cabinets, general meeting
Equipped with directional over-current protection, electric current time limit fast tripping protection, the low all oscillation and splitting protections of low pressure, synchronous loss of synchronism protection etc., also some
Protection is disperseed to be installed to each place, in existing shaped steel grid-connection cabinet field, the support body of many grid-connection cabinets is all to pass through type
Material welds together, and so not only increase is welded and polishing operation, including maintenance, the replacing of grid-connection cabinet support body are inconvenient and whole
Individual support body easily accounts for the space of phosphating pond and spray painting room when being surface-treated, and substantially reduces production efficiency.Therefore, we carry
Go out it is proposed that a kind of grid-connection cabinet framework connecting piece.
The content of the invention
It is an object of the invention to provide a kind of grid-connection cabinet framework connecting piece, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of grid-connection cabinet framework connecting piece, including side plate,
Plate muscle, fine setting hole, positioning hole and nut fixing groove, the side plate is L-shaped, and three side plates are mutually perpendicular to weld, the side plate
It is uniformly distributed four positioning holes in the middle part of two planes of symmetry, the fine setting pore size distribution is among two positioning holes the side plate is vertical
In face nut fixing groove is equipped with the positioning hole of survey and fine setting hole.
Preferably, the positioning hole is circular hole.
Preferably, the side plate is made of alloy in lightweight steel.
Preferably, the rectangular equilateral triangle of plate muscle is connected on the inner side edge of side plate two.
Preferably, the fine setting hole is two intersecting borehole structures.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is applied to grid-connection cabinet frame corners and is fixedly connected, during assembling, every a pair of vertical panels face and FRAME COMPONENTS
Corresponding, positioning hole is circular hole, and for being connected by screw with FRAME COMPONENTS, fine setting hole is two intersecting borehole structures, such as
In the case that fruit size has error, the space of screw movement can be left for, play an adjustment effect, plate muscle makes whole joint angle
More firm, nut fixing groove with hold-doun nut, can facilitate the fixation of screw, and grid-connection cabinet framework connecting piece can connect can be with
The frame unit in three directions, the welding avoided and polishing operation are connected, and whole support body easily accounts for when being surface-treated
The space of phosphating pond and spray painting room, substantially reduces production efficiency.
2nd, the present invention facilitates manufacture craft, installation, replacing and the maintenance of grid-connected cabinet frame work.
