Description
Technical field
The utility model belongs to field of power, and in particular to a kind of Scratch-proof box-type transformer substation.
Background technology
Scratch-proof box-type transformer substation be for changing voltage equipment, in order to the electrical energy transportation that power plant issues to farther out
Place, it is necessary to voltage is raised, to user near voltage is being reduced as required, anti-scratch is leaned in the work of this buck/boost
Box-type substation is completed, Scratch-proof box-type transformer substation capital equipment city switch and transformer, different by scale, and it is box to be known as anti-scratch
Substation, electric substation and switchgear house etc..
There are two types of the mating box Scratch-proof box-type transformer substations of current existing wind power plant, first, the box anti-scratch of combined type
Box-type substation, i.e. American Unit Substation, second is that European-type box becomes.But existing European-type box, which becomes, to be become with conventional case in contour structures
And arrangement is all close, also similar including transformer, basic function is identical, is all the 40.5kV intelligence using wind-power electricity generation
Box Scratch-proof box-type transformer substation is pre-installed, the low pressure for completing wind-powered electricity generation by booster system is finally connected to the grid to the conversion of high pressure.
It is exactly three-phase alternating currents of the 0.69kV without fixed frequency that wind power generating set is sent, 0.69kV, 50Hz is formed by frequency converter
Three-phase alternating current, by Wind turbines controller, by alternating current, most of by the special 40.5kV of wind-powered electricity generation, intelligently prepackage is box anti-
The low-voltage circuit breaker access step-up transformer of box-type substation is drawn, step-up transformer is 40.5kV 0.69kV boostings, then is passed through
40.5kV vacuum load switch and fuse combined electric apparatus access power transmission network.Meanwhile another fraction alternating current is passed through into anti-scratch
