Abstract

The utility model discloses an intelligent on-load dry type regulated capacity transformer, which comprises a dry type transformer, an intelligent controller and an on-load regulated capacity switch cabinet, wherein the dry type transformer is connected with the intelligent controller and the on-load regulated capacity switch cabinet respectively; and the intelligent controller is also connected with the on-load regulated capacity switch cabinet. According to the intelligent on-load dry type regulated capacity transformer, a load condition of the dry type transformer can be detected in real time through the intelligent controller, so that switching between series connection and parallel connection of coils of the dry type transformer is controlled through the on-load regulated capacity switch cabinet, and finally rational loss of the transformer is guaranteed. The intelligent on-load dry type regulated capacity transformer has the advantages of simple structure, rational design, obvious power saving effect, capability of effectively reducing the noise of the transformer and suitability for power supply of industrial and mining enterprises and institutions and residential districts.

Description

Intelligent have carry a dry type capacitance-adjustable transformer

Technical field

The utility model belongs to power industry, and what be specifically related to a kind of power savings significantly and can effectively reduce transformer noise intelligently has a dry type capacitance-adjustable transformer of carrying.

Background technology

Existing dry-type transformer no-load loss standard is very large, and industrial and mineral enterprises and institutions power load alters a great deal, during working at full capacity, zero load almost when next; The new residential area occupancy rate is very low, and it is very little to load, and there are several periods old residential quarters, and it is larger to load, and most of load is all lower.Therefore load little the time, jumbo dry-type transformer no-load loss is very large, and 1 year through calculating, and the electricity of waste is very large.

The utility model content

The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, provides a kind of reasonable adjustment transformer loss with saves energy intelligent the dry type capacitance-adjustable transformer of carrying to be arranged.

Technical scheme: a kind of intelligent dry type capacitance-adjustable transformer of carrying that has described in the utility model, comprise dry-type transformer, intelligent controller and loaded capacity-regulated switch cubicle, described dry-type transformer is connected with intelligent controller, described intelligent controller also is connected with loaded capacity-regulated switch cubicle, and described loaded capacity-regulated switch cubicle is connected with dry-type transformer.

Described intelligent controller is the intelligence control system that adopts FUZZY ALGORITHMS FOR CONTROL.

The utility model is adjusted the capacity transfer switch cubicle by intelligent controller, thereby finish the transformer height, the handoff procedure of low capacity, the specific works principle is as follows: intelligent controller is by the voltage of monitoring step down side, electric current is judged current payload, according to the capacity setting value and judge the related constraint condition, satisfying imposes a condition then sends corresponding adjusting control command to loaded capacity-regulated switch cubicle, loaded capacity-regulated switch cubicle sends opening and closing movement according to control command to switch in the transformer, it is inner high to finish transformer, the string of low-voltage coil, conversion in parallel, 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 does not need to have a power failure, finish the transformer capacity adjustment process.

Beneficial effect: the utility model 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

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1 a kind of intelligent has the dry type capacitance-adjustable transformer of carrying, comprise dry-type transformer, intelligent controller and loaded capacity-regulated switch cubicle, wherein dry-type transformer is connected with intelligent controller, 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, but the folding of switch in the high and low pressure coil in the loaded capacity-regulated switch cubicle control transformer, thereby the series and parallel of realizing the high and low pressure coil is changed.

Design principle of the present utility model is: Three-Phase Transformer high pressure winding connecting mode high and low pressure coil when large 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 the utility model dry-type transformer as shown in Figures 2 and 3 coil connection layout when large volume load, wherein K1, K2 are closed, and K3 disconnects, and makes the high and low pressure coil be in state in parallel; The inner high and low pressure coil of the utility model dry-type transformer coil connection layout when big or small volume load as shown in Figure 4 and Figure 5, wherein K1, K2 disconnect, 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, automatically to finish by 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 is converted to the low capacity load by large volume load, because coil turn is increased to 2 times, then the induced potential on the every circle coil of former avris reduces, 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, therefore unloaded reactive loss and the active loss of transformer reduce greatly, when the unloaded reactive loss of low capacity load is about large volume load 1/10 of loss, when active loss is about large 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 the utility model transformer and common transformer contrast with loss of electricity in factory, and table two is that the utility model transformer and common transformer contrast with loss of electricity in residential quarters.
