Description
Technical field
The utility model relates to a kind of oil-filled transformer, what be specifically related to is all lower 1 grade of oil immersed energy-saving transformers of efficiency of a kind of no-load loss and load loss.
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 S11 type transformer no-load loss has approximately reduced by 20% than original S9 type transformer noload losses, load loss does not reduce, while causing transformer belt load running the electricity charge higher, waste energy, uneconomical.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to be to provide a kind of 1 grade of oil immersed energy-saving transformer of efficiency all reducing than existing S11 type oil-filled transformer no-load loss and load loss.
To achieve these goals, the utility model is to realize by the following technical solutions:
1 grade of oil immersed energy-saving transformer of a kind of efficiency; it comprises: transformer body and protection equipment for transformer; described transformer body comprises fuel tank and is arranged on the transformer body in fuel tank; described protection equipment for transformer comprises pressure relief valve, temperature controller, Buchholz relay protective device; described pressure relief valve is installed on top of oil-tank; described temperature controller; be installed on transformer oil tank wall and by capillary, be connected on the obturating plug of top of oil-tank; described Buchholz relay, is installed on the top of oil tank of transformer.
Described transformer body is comprised of iron core and the winding being arranged on outside iron core,
Described winding comprises the low-voltage coil being enclosed within on iron core stem stem and is wrapped in the high-tension coil outside low-voltage coil.
The utility model is rational in infrastructure, stable performance, practical, than S9 type no-load loss, has reduced by 50%, and load loss has reduced by 20%; Than S11 type no-load loss, reduced by 30%, load loss has reduced by 20%, very energy-conservation.
Accompanying drawing explanation
Fig. 1 is the structural representation of 1 grade of oil immersed energy-saving transformer of a kind of efficiency of the utility model.
Fig. 2 is the vertical view of 1 grade of oil immersed energy-saving transformer of a kind of efficiency of the utility model.
In figure: 1-transformer body, 2-oil tank of transformer, 3-transformer body, 4.1-pressure relief valve, 4.2-temperature controller, 4.3-Buchholz relay.
Embodiment
Below in conjunction with accompanying drawing, further set forth the utility model.
Referring to Fig. 1 and Fig. 2; 1 grade of oil immersed energy-saving transformer of a kind of efficiency; it comprises: transformer body 1 and protection equipment for transformer; described transformer body 1 comprises oil tank of transformer 2 and is arranged on the transformer body 3 in fuel tank; described protection equipment for transformer comprises pressure relief valve 4.1, temperature controller 4.2 and Buchholz relay 4.3; described pressure relief valve 4.1 and Buchholz relay 4.3 are all installed on oil tank of transformer 2 tops, and described temperature controller 4.2 is installed on oil tank of transformer 2 casings.
The signal input part of described temperature controller 4.2 is arranged on oil tank of transformer 2 outer wall tops, the signal output part of temperature controller 4.2 is connected on the obturating plug at oil tank of transformer 2 tops by capillary, in order to detect, to show transformer oil top layer temperature, when the interior top-oil temperature of oil tank of transformer 2 surpasses set point, temperature controller 4.2 sends reports to the police and trip signal.
Described transformer body 3 is comprised of iron core and the winding being arranged on outside iron core, and described winding comprises the low-voltage coil being enclosed within on iron core stem stem and is wrapped in the high-tension coil outside low-voltage coil.
Described iron core is formed by stacking by grain-oriented cold-reduced silicon sheet.
Described pressure relief valve 4.1, when transformer inside has an accident, when the pressure V in fuel tank reaches the operating pressure value of pressure relief valve 4.1, pressure relief valve 4.1 is opened, and discharges in time the overvoltage in fuel tank, protects reliably fuel tank not to be damaged; When the pressure V in fuel tank is down to the closing presure value of pressure relief valve 4.1, pressure relief valve 4.1 is reliably closed, and guarantees that transformer oil is non-leakage, makes the pressure of fuel tank internal forever keep malleation, effectively prevents entering of extraneous air, dust, steam.Pressure in fuel tank increases again, and while reaching the operating pressure value of pressure relief valve 4.1, pressure relief valve 4.1 is action again just.
Described Buchholz relay 4.3 is the protection that overflows of the device in Gas scale of construction for light transformer protection.During transformer normal operation, in relay, be full of transformer oil, if transformer breaks down in the course of the work, transformer oil decomposes and the gas that produces will be collected at the top of Buchholz relay 4.3 containers, force the float of Buchholz relay 4.3 to decline, when float is down to alarm position, relay internal magnet is connected signal, sends alarm signal.
The utility model is 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 iron loss is low, very energy-conservation.
