The permission temperature rise of 35kV level vegetable insulating oil H class F insulation power transformer improves a lot, can make transformer save a lot of materials, and transformer has very high overload performance, because vegetable oil derives from agricultural product, belong to recyclable materials, and difficult combustion, has good fire-fighting performance, after transformer application, will produce immeasurable economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of high-tension coil, low-voltage coil and main channel.
Embodiment
As shown in Figure 1, the utility model comprises transformer-cabinet 10, in casing 10, is contained with insulating oil, and insulating oil of the present utility model adopts vegetable insulating oil.
Vegetable insulating oil is applied to 35kV level power transformer by the utility model, and by improving relevant insulating material, the integral insulation level that makes transformer is H level, and top layer oil allows temperature rise 100K, and it is 115K that coil allows average temperature rising.The permission temperature rise of 35kV level vegetable insulating oil H class F insulation power transformer improves a lot, and this can make transformer save a lot of materials, and transformer has very high overload performance, and vegetable insulating oil belongs to recyclable materials, and difficult combustion, has good fire-fighting performance.
Be common transformer oil and common oil-filled transformer uses, insulation level is A level, and it is 55K that top layer oil allows temperature rise, and it is 65K that coil allows average temperature rising.
As shown in Figure 2, the utility model also comprises iron core 1 and coil 2, coil 2 comprises high-tension coil 2-1 and low-voltage coil 2-2, between high-tension coil 2-1 and low-voltage coil 2-2, it is main empty path 7, in main empty path 7, select two stupid ether insulation boards, two stupid ether insulation strip to make the form of stay curtain, effectively increase the area of dissipation of main empty path, improved the radiating effect of coil.
Existing common oil-filled transformer main empty path generally selects paperboard strip and insulating paper to make the form of stay curtain, and paperboard strip and insulating paper are all A class F insulating material F, can only tolerate the temperature of 105 DEG C.And two stupid ether insulation boards of the present utility model, two stupid ether insulation strip are all H class F insulating material F, can tolerate the temperature of 180 DEG C.
Layer insulation of the present utility model is selected organosilicon glass paint cloth, organosilicon glass paint cloth is H class F insulating material F, can tolerate the temperature of 180 DEG C, because organosilicon glass paint cloth has good insulation property, its dielectric strength is high, its insulation withstand voltage is up to 8 ~ 10kV/0.1mm, be much higher than common insulating paper, thereby reduced the thickness of layer insulation, the width of transformer coil is reduced to size, save the consumption of coil copper cash, the volume of transformer is reduced.So both save material, reduced cost, improved again the insulation property of transformer.And common oil-filled transformer layer insulation is generally selected insulating paper, it is A class F insulating material F.
