Background technology
Along with national development, power load sharply increases, and the installation quantity of transformer is more and more, and transformer himself will produce the loss (being the summation of no-load loss and load loss) of active power in the process of through-put power, need to consume a large amount of electric energy.Although novel SCB10 type transformer has reduced by 10% than original SCB9 type transformer noload losses, load loss has reduced by 5%, and total losses are still very high, causes transformer when operation electricity charge higher, wastes energy, uneconomical.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to provide and a kind ofly all reduces by 1 grade of dry type energy-economic transformer of a lot of efficiencies than existing SCB10 type dry-type transformer no-load loss and load loss.
The technical scheme that the utility model is taked is: 1 grade of dry type energy-economic transformer of a kind of efficiency, and it comprises transformer body, cooling blower and temperature controller protective device; Described transformer body comprises the annex that transformer body and fixture body are used, and described cooling blower and temperature controller protective device are arranged on transformer body; The device body of described transformer is made up of iron core and winding, and iron core is formed by stacking by grain-oriented cold-reduced silicon sheet.
In scheme, described cooling blower is installed on transformer body bottom; Described iron core is provided with winding outward, and winding comprises low-voltage coil and is arranged on the high-tension coil outside low-voltage coil; Described temperature controller protective device is made up of thermistor and temperature-controlled cabinet two parts, and described thermistor is installed on low voltage winding in transformers inside upper part, and temperature-controlled cabinet is installed on transformer body top.
As preferred version, described cooling blower adopts low noise cross-flow cooling fan; Described thermistor is Pt100 thermistor; And on temperature-controlled cabinet, be provided with display screen, can show the transformer temperature numerical value that thermistor is measured.
The utility model is rational in infrastructure, stable performance, practical, has reduced by 35% than SCB9 type no-load loss, and load loss has reduced by 15%; Reduced by 25% than SCB10 type no-load loss, load loss has reduced by 5%, very energy-conservation.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 to Fig. 4,1 grade of dry type energy-economic transformer of a kind of efficiency, it comprises transformer body 1, cooling blower 4 and temperature controller protective device; Described transformer body 1 comprises the annex that transformer body and fixture body are used, and described cooling blower 4 and temperature controller protective device are arranged on transformer body; The device body of described transformer is made up of iron core 3 and winding 2, and iron core 3 is formed by stacking by grain-oriented cold-reduced silicon sheet.
Described cooling blower 4 is installed on transformer body bottom, and cooling blower 4 can adopt low noise cross-flow cooling fan.The outer winding 2 that is provided with of described iron core 3, winding 2 comprises low-voltage coil and is arranged on the high-tension coil outside low-voltage coil.Described temperature controller protective device is made up of thermistor 5.1 and temperature-controlled cabinet 5.2 two parts; Described thermistor 5.1 is installed on low voltage winding in transformers inside upper part, and temperature-controlled cabinet 5.2 is installed on transformer body top.Temperature-controlled cabinet 5.2 is provided with display screen, can show the transformer temperature numerical value that thermistor 5.1 is measured; Thermistor 5.1 is Pt100 thermistor.
In force, transformer body comprises the annex compositions such as cushion block that device body and fixture body use, folder, feet.The device body of transformer is made up of iron core and winding, and iron core is placed on inside, and iron core is provided with winding outward, and winding comprises low-voltage coil and is arranged on the high-tension coil outside low-voltage coil.Wherein, iron core is to be formed by stacking by grain-oriented cold-reduced silicon sheet, and no-load loss is very low, and performance reaches the level of W23ZH90 silicon steel sheet, and magnetic flux density is below 1.5T, and noise is lower, and iron loss is less, very energy-conservation.
In addition, cooling blower, adopts low noise cross-flow cooling fan, every two blower fans, altogether six blower fans installed mutually; Be installed on transformer body bottom, can improve the power output 40-50% of dry-type transformer, can greatly improve dry-type transformer overload capacity and extend useful life of dry-type transformer.Temperature controller is made up of Pt100 thermistor and temperature-controlled cabinet two parts, and Pt100 thermistor is used for measuring transformer hottest spot temperature signal, then is transferred to temperature-controlled cabinet.In the time that temperature exceedes set point, control respectively the startup of cooling blower and stop, and exportable overtemperature alarm and overtemperature trip signal; On temperature-controlled cabinet, display screen also can show the transformer temperature numerical value that Pt100 thermistor is measured, and can log history maximum temperature, guarantees the safe and reliable operation of power supply-distribution system.
