Description
Technical field
The invention belongs to power industry, be specifically related to a kind of power savings significantly and can effectively reduce transformer noise intelligent the dry type capacitance-adjustable transformer of carrying arranged.
Background technology
Existing dry-type transformer no-load loss standard is very big, and industrial and mineral enterprises and institutions power load alters a great deal, during working at full capacity, zero load almost when next; Newly-built residential quarters occupancy rate is very low, and it is very little to load, and there are several periods old residential quarters, and it is bigger to load, and most of load is all lower.Therefore load little the time, jumbo dry-type transformer no-load loss is very big, and 1 year through calculating, and the electricity of waste is very big.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, provide a kind of reasonable adjustment transformer loss the dry type capacitance-adjustable transformer of carrying to be arranged with saves energy intelligent.
Technical scheme: a kind of intelligent dry type capacitance-adjustable transformer of carrying that has of the present invention; Comprise dry-type transformer; Intelligent controller and loaded capacity-regulated switch cubicle; Said dry-type transformer is connected with intelligent controller, and said intelligent controller also is connected with loaded capacity-regulated switch cubicle, and said loaded capacity-regulated switch cubicle is connected with dry-type transformer.
Said intelligent controller is the intelligence control system that adopts FUZZY ALGORITHMS FOR CONTROL.
The present invention exchanges the appearance switch cubicle through intelligent controller and adjusts; Thereby accomplish the handoff procedure of the high and low capacity of transformer; Concrete operation principle is following: intelligent controller is judged current payload through voltage, the electric current of monitoring step down side, and according to the capacity setting value and judge the related constraint condition, satisfying imposes a condition then sends corresponding adjusting control command and give loaded capacity-regulated switch cubicle; Loaded capacity-regulated switch cubicle sends opening and closing movement according to control command to switch in the transformer; Accomplish the series and parallel conversion of the inner high and low pressure coil of transformer, its magnetic flux density unshakable in one's determination is correspondingly changed, reach the purpose of the loss that reduces its capacity; Under the state that need not have a power failure, accomplish the transformer capacity adjustment process.
Beneficial effect: the present invention is simple in structure, and is reasonable in design, and power savings is remarkable and can effectively reduce transformer noise, is applicable to the power supply of industrial and mineral enterprises and institutions and residential quarters.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
A kind of intelligent dry type capacitance-adjustable transformer of carrying that has as shown in Figure 1; Comprise dry-type transformer; Intelligent controller and loaded capacity-regulated switch cubicle, wherein dry-type transformer is connected with intelligent controller, and intelligent controller also is connected with loaded capacity-regulated switch cubicle; Loaded capacity-regulated switch cubicle is connected with dry-type transformer; Intelligent controller is the intelligence control system that adopts FUZZY ALGORITHMS FOR CONTROL, the folding of switch in the high and low pressure coil in the loaded capacity-regulated switch cubicle may command transformer, thus the series and parallel of realizing the high and low pressure coil is changed.
Design principle of the present invention is: transformer three-phase high-voltage winding connecting mode high and low pressure coil when big volume load is parallel form, and the high and low pressure coil is the series connection form during low capacity load.
The inner high and low pressure coil of dry-type transformer of the present invention as shown in Figures 2 and 3 is the coil connection layout when big volume load, and wherein K1, K2 are closed, and K3 breaks off, and makes the high and low pressure coil be in parallelly connected state; Like Fig. 4 and the inner high and low pressure coil of dry-type transformer of the present invention shown in Figure 5 coil connection layout when the big or small volume load, wherein K1, K2 break off, and K3 is closed, makes the high and low pressure coil be in series connection.
Change coil windings also, the conversion of series connection; By the intelligence control system (being intelligent controller) that adopts FUZZY ALGORITHMS FOR CONTROL, to accomplish automatically through controlling loaded capacity-regulated switch cubicle, above-mentioned adjustment reduces phase voltage; And the number of turn and voltage are inversely proportional to, and guarantee that finally output voltage is constant; When transformer converts the low capacity load into by big volume load; Because coil turn is increased to 2 times, the induced potential on the every circle coil of then former avris reduces, and magnetic flux density unshakable in one's determination significantly reduces; The silicon steel sheet specific loss diminishes; Thereby no-load loss and no-load current also decline to a great extent, so the unloaded reactive loss and the active loss of transformer reduce greatly, when the unloaded reactive loss of low capacity load is about big volume load 1/10 of loss; When active loss is about big volume load 1/3 of loss, energy conservation and consumption reduction effects is obvious.
Correction data is as shown in the table, and table one is that transformer of the present invention and common transformer contrast with the loss electric weight in factory, and table two is that transformer of the present invention and common transformer contrast with the loss electric weight in residential quarters.
