Description
Technical field
The invention belongs to field of power, and in particular to a kind of transformer station.
Background technology
Transformer station is to be used to change the equipment of voltage, in order to which electrical energy transportation that power plant is issued is to place farther out,
Voltage must be raised, to user near voltage is being reduced as required, the work of this buck/boost has come by transformer station
Into capital equipment city of transformer station switch and transformer are different by scale, referred to as transformer station, electric substation and switchgear house etc..
The supporting box-type substation of current existing wind power plant has two kinds, and one is composite type cabinet type transformer substation, i.e., beautiful
Formula case becomes, and second is that European-type box becomes.But existing European-type box becomes to be become in contour structures and arrangement all phases with conventional case
Closely, including transformer is also similar, basic function phase is same, is all intelligently to pre-install box type transformation using the 40.5kV of wind-power electricity generation
Stand, the low pressure for completing wind-powered electricity generation by booster system is finally connected to the grid to the conversion of high pressure.Namely wind power generating set is sent
Three-phase alternating currents of the 0.69kV without fixed frequency, by frequency converter formation 0.69kV, 50Hz three-phase alternating current passes through wind
Motor group controller connects the most of low-voltage circuit breaker by the intelligent pre-casing type transforming stations of the special 40.5kV of wind-powered electricity generation of alternating current
Enter step-up transformer, step-up transformer is 40.5kV 0.69kV boostings, then passes through 40.5kV vacuum load switch and fusing
Device combined electrical apparatus accesses power transmission network.Meanwhile, another fraction alternating current is become into pressure drop 0.38kV by the control in transformer station, made
The power supply for needed for switch and the control of breaker and intelligent control device.Wherein high-pressure section is provided with arrester and powered
Aobvious device etc..
Existing transformer station does not have shockproof function typically, and earthquake in recent years takes place frequently, at the same all transformer stations be likely to by
To impact；Existing power transformation is fried, the annex for only being handled cable socket and being connected in casing, relatively simple for structure, volume
Smaller, function is relatively simple；Existing transformer station, box-type substation includes the casing being made up of bottom plate, wallboard and top plate, casing
Inner route clapboard is separated into hyperbaric chamber, pressure change chamber and low-pressure chamber, and hyperbaric chamber, pressure change chamber and low-pressure chamber correspond to place high-voltage switch gear respectively
Equipment, distribution transformer and low-voltage distribution equipment, in order to radiate the need for open up ventilating opening in wallboard and top plate, needing enhancing
During radiating effect, exhaust blower can be also installed at the ventilating opening of top plate.Because the ventilating opening on top plate is in the surface of casing,
Although employing cover plate above ventilating opening to prevent rainwater from entering, dust or the easily sky between cover plate and top plate
Between enter in casing, being splashed into for rainwater or falling into for the foreign matter such as insect can not be avoided completely, easily transformer is caused
Influence, goes back the safety of entail dangers to transformer, or even lead to fire incident when serious.And, although there is provided discharge machine, but case
There are still radiating dead angle in vivo, it is impossible to improves air flow property, radiating effect is undesirable.
Therefore, it is necessary to be improved to existing transformer station, while enabling to transformer station's ventilation preferable, with compared with
Good cushioning effect.
