Description of drawings
Fig. 1 is a structural profile front view of the present utility model (housing is cut open).
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
By shown in Figure 1; the utility model comprises transformer body and housing; transformer body 1 is contained in the housing 7; in the other housing of transformer body, data acquisition unit 5, singlechip controller 3, driver 4, controllable silicon noncontacting switch 2 and over current protection reactance 6 are housed; transformer body links to each other with the controllable silicon noncontacting switch; transformer body links to each other with singlechip controller through data acquisition unit; connect over current protection reactance and driver on the controllable silicon noncontacting switch respectively, driver links to each other with singlechip controller.Data acquisition unit 5, singlechip controller 3, driver 4 can be contained on one's body the device of transformer body.
In order to guarantee result of use, said data acquisition unit can adopt the SD-SC-01 data acquisition unit, singlechip controller adopts the SD-KZ-02 singlechip controller, driver can adopt the SD-QD-03 driver, protection reactor can adopt the SD-DK-04 protection reactor, is commercially available existing product with upper-part; Said transformer body is to be made of high pressure winding, low pressure winding, amorphous alloy iron core and device body, high pressure winding and low pressure winding alternately are wound on the amorphous alloy iron core, and the mode of connection that the conversion of the large and small capacity of transformer mainly relies on controllable silicon noncontacting switch execution architecture to change the high and low pressure winding realizes.The low pressure winding is made up of the little wire turn that is cascaded, big wire turn, and little wire turn is by a lead coiled, and big wire turn is by two leads and around forming, and the high pressure winding is made up of at least two group coil tandems.Each is organized coil and has separately coil tap, and the high and low pressure coil tap connects controllable silicon noncontacting switch (this switch can adopt loaded capacity-regulated switch) respectively.Under the situation of not cutting off load, adjust capacity with the connected mode of controllable silicon noncontacting switch conversion high-low pressure winding, the output capacity of transformer generally has the 7-10 shelves.
Said singlechip controller, driver and data acquisition unit constitute control structure (control system), this structure can be implemented under the situation of carrying, according to the transformer load real time status transformer capacity is automaticallyed switch, under the situation of not cutting off the power supply, carry out capacity automatically by the controllable silicon noncontacting switch and switch, can effectively reduce the transformer running wastage according to the size of power consumption; Controllable silicon noncontacting switch and transformer body constitute execution architecture, to satisfy the needs of load.
By said structure as can be seen, control system partly comprises: (1) single-chip computer control system---the voltage and current data according to real-time collection are handled, and generate real-time load, and described real-time load and the definite value of presetting of transferring the files are compared, generate comparative result, send control command; (2) real-time data acquisition unit---it is connected with transformer, gathers the data such as voltage, electric current and power factor of step down side in real time; (3) automatic capacity transfer control drive unit---connect the contactless capacity transfer switch of controllable silicon of transformer, if load in real time is greater than the preset value of transferring the files, then the contactless capacity transfer switch of controllable silicon shown in the control will have the capacity that carries transformer to switch to high tap position, otherwise, then control the contactless capacity transfer switch of described controllable silicon the capacity of transformer switched to low-grade location.This control system can be implemented under the situation of carrying, and according to the transformer load real time status transformer capacity is automaticallyed switch.
The utility model can not only realize effectively reducing transformer loss, and can gather the transformer health information automatically in real time, monitor and control, and according to the actual load size, reasonably carry out the automatic adjusting of capacity, can further enlarge the scope of application of capacitance-adjustable transformer, widen application.It is applicable to that network load changes greatly, the demanding occasion of quality of voltage.
The utility model is for reducing loss as far as possible, can rationally adjust the capacity of transformer according to the electricity consumption characteristics of town and country, enterprise with the automatic switchover of in time loading of the load factor of transformer, runs on the optimum load state to guarantee transformer.Transformer core is the amorphous alloy material, at high temperature, condense under the high pressure, form the electrical transformer cores sheet through annealing in process, its no-load loss has bigger decline than traditional silicon sheet core transformer, no-load current descends about 80%, obvious energy-saving effect is arranged, and is the 25%-30% of S9 serial transformer only as the no-load loss of amorphous alloy transformer, is well suited for the transformer load rate and uses lower place.So, adopt the loaded capacity-regulated formula transformer of amorphous alloy material can satisfy above requirement simultaneously.It can have two capacity of size, can automatically adjust to capacity by loaded capacity-regulated switch according to the actual load size, is highly suitable for peak of power consumption and the bigger occasion of low ebb load variations amplitude.When loading light or approaching zero load, be adjusted to low capacity automatically and move, can reduce no-load loss significantly by big capacity; When load enters the bad operation of heavy load, automatically switch to big capacity, effectively reduce load loss, thereby realize significantly energy-conservation effect by low capacity.
Therefore, combine with loaded capacity-regulated switch, develop loaded capacity-regulated formula amorphous alloy transformer and provide new implementation, can effectively solve and eliminate existing existing problem of distribution transformer and limitation for reducing transformer loss with amorphous alloy material.The no-load loss of this transformer and load loss all are lower than the S serial transformer, and especially the total losses when low capacity moves are more much lower than the total losses of the standard transformer of same capability.
