Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1; the special-purpose amorphous iron core variable capacitance and energy-saving transformer of this kind oil pumper; comprise protection equipment for transformer 1, bushing 2, shunting switch 3, low-tension bushing 4, lead-in wire 5, wire clamp 6, iron core 7, coil 8, fuel tank 9, transformer oil 10, wherein described iron core 7 according to conventional core structure change has been taken place.Its concrete structure is: combine the three-phase five-limb structure by four independently rectangle volume iron cores 11 as shown in Figure 2.Wherein, described volume iron core 11 adopts overlap joint iron yoke 12 seams, has simplified technology and tooling device, and the better protect magnetic property makes it reach optimum, thereby can further reduce no-load loss.
Through experimental results demonstrate, described volume iron core 11 adopts the thick effect optimum when being the amorphous alloy film of 0.03mm of sheets.Here winding can be the rectangle cross section, and the bilayer of coiling moulding or multilayer rectangle laminar are that minimizing copper material consumption 5% is compared in round cross section with winding separately, and fuel tank is the ripple struction of full sealed non-maintenance.Compare with similar transformer, the close selective value of magnetic descends 28%, and electric close value descends about 41%, and impedance adjusts to 3.6%.The technological coefficient span should be 1.11, and joint group adopts the Dynll connecting method.
After using the technical program, because this main component of transformer is amorphous magnetic circuit iron core and the high-voltage coil and low-voltage coil that constitutes the three-phase electric energy transmission, in actual design, use electromagnetic induction principle, by four independently rectangle volume iron core combine the three-phase five-limb structure, under this structure, adjust the current density of high-voltage coil and low-voltage coil, can make the current density value descend 50%~60% according to the conventional transformer value, beam overall unshakable in one's determination increases by 15%~20%, height overall unshakable in one's determination increases by 6%~10%, thereby has determined the magnetic flux density of suitable iron core.Adjust corresponding impedance, compare with domestic similar SH11 product, when guaranteeing that impedance reaches the GB requirement, transformer capacity can be regulated in 0.8~2.0 times of scope.In the oil pumper work, can reduce about 50% when transformer capacity and motor coupling, satisfy the job requirement of heavy load starting and stress alternation, promptly under rated capacity, can reach exerting oneself of double capacity, and transformer loss is the loss under the rated capacity, reaches automatic capacity transfer purpose, energy-saving effect is remarkable, applicability is strong, makes transformer capacity can satisfy the oil pumper operating characteristic automatically.Non-crystaline amorphous metal capacitance-adjustable transformer and oil pumper configuring condition: as used for oil extractor 37kW motor, former adapted SH11-63kVA transformer, now can select for use capacity transfer to become the RSH11-30kVA transformer, transformer capacity is saved half, no-load loss descends 67%, load loss descends 42.3%, about 6000 yuan of the Spring Festival holidays electricity charge.This transformer is safeguarded simple and convenient, and energy-saving effect is remarkable, is suitable for various oil pumpers and uses.
