Description
Technical field
The utility model relates to a kind of fuel tank that is used to install the bell-jar transformer.
Background technology
The structure of general bell-jar oil tank of transformer has Fig. 1, two kinds of forms shown in Figure 2, generally includes: conservator 7, go up at the bottom of fuel-economizing case 1, lower oil tank 3 and the fuel tank 5, transformer body is arranged in the fuel tank; The fuel tank of these two kinds of forms has a common ground: the faying face 2 of going up fuel-economizing case 1 and lower oil tank 3 is a horizontal plane, is described respectively with regard to these two kinds of fuel tanks below.Fuel tank shown in Figure 1, fuel-economizing case 1 is very high on it, lower oil tank 3 is very short, the connecting portion of the device body of transformer and low pressure outlet copper bar 4 bolts is all in last fuel-economizing case 1, high-voltage connection 9 and on-load voltage regulating switch 8 also all are buckled in the fuel-economizing case 1, and the mechanical endurance of general homemade on-load voltage regulating switch 8 is about 10,000 times, once overhauling once to 2 years needs, will lay down thousands of bolts of tens even hundreds of that transformer body is connected with low pressure outlet copper bar 4 during maintenance earlier, and just can hang fuel-economizing case 1 and carry out the maintenance of on-load voltage regulating switch 8 and transformer body.Buckle the fuel-economizing case after having overhauled, the bolt that the transformer body of screwing on again is connected with low pressure outlet copper bar 4, service work extremely bothers.Fuel tank shown in Fig. 2, fuel-economizing case 1 is very short on it, lower oil tank 3 is very high, the connecting portion of the device body of transformer and low pressure outlet copper bar 4 bolts and on-load voltage regulating switch 8 all in lower oil tank, during maintenance, hang fuel-economizing case 1 after, most of on-load voltage regulating switch 8 and high-voltage connection 9 still are in the lower oil tank 3, still can't overhaul, only lay down the device body and a large amount of bolts that low pressure outlet copper bar 4 is connected of transformer, hang out that the device body exposes whole on-load voltage regulating switch 8 and high-voltage connection 9 could overhaul.In fact, transformer body is all very heavy, and is light tens tons, and heavy tens tons, the general user does not possess so ability of heavy transformer body of lifting.Above-mentioned two kinds of fuel tanks, in the fuel-economizing case, work brings very burden to repair and maintenance because on-load voltage regulating switch 8 and high-voltage connection 9 and the low pressure outlet copper bar 4 that stretches out fuel tank exist together.
The utility model content
Technical problem to be solved in the utility model provides a kind of on-load voltage regulating switch that can allow rapid wear and high-voltage connection and the bell-jar oil tank of transformer of the low pressure outlet copper bar office two fuel-economizing casees seldom changed.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the bell-jar oil tank of transformer, comprise: at the bottom of conservator, last fuel-economizing case, lower oil tank and the fuel tank, conservator is fixedly installed on the fuel-economizing case, last fuel-economizing case is provided with bushing, be fixed together on last fuel-economizing case and the lower oil tank, on lower oil tank was fixedly installed at the bottom of the fuel tank, the faying face of last fuel-economizing case and lower oil tank was the low tilting structure of the high end of an end.
A kind of concrete form of above-mentioned tilting structure is a stairstepping.
The another kind of concrete form of above-mentioned tilting structure is a gradient shape.
The gradient of above-mentioned gradient shape and the angle of horizontal plane are 30 to 70 degree.
The beneficial effects of the utility model are: because the faying face of going up fuel-economizing case and lower oil tank described in the utility model is the low tilting structure of the high end of an end, thereby the on-load voltage regulating switch and the high-voltage connection of rapid wear can be arranged in the fuel-economizing case, and the low pressure outlet copper bar that will seldom change is arranged in the lower oil tank.During maintenance, as long as hang the fuel-economizing case, just can overhaul, thereby save the trouble of dismantling a large amount of bolts and hanging out transformer body on-load voltage regulating switch and high-voltage connection place.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing, but the utility model should not only limit to this two embodiment.
The faying face of 1: two fuel-economizing case of embodiment is step-like bell-jar oil tank of transformer
As shown in Figure 3, the bell-jar oil tank of transformer, comprise: conservator 7, go up at the bottom of fuel-economizing case 1, lower oil tank 3 and the fuel tank 5, conservator 7 is fixedly installed on the fuel-economizing case 1, offer bushing 6 on the last fuel-economizing case 1, last fuel-economizing case 1 is fixed together with lower oil tank 3, and lower oil tank 3 is fixedly installed at the bottom of the fuel tank on 5, and the faying face 2 of last fuel-economizing case 1 and lower oil tank 3 is the low stairstepping setting of the high end of an end.Such setting can be arranged in the on-load voltage regulating switch 8 of rapid wear and high-voltage connection 9 in the fuel-economizing case 1 and is positioned at the lower end of fuel-economizing case 1, and the low pressure outlet copper bar 4 that will seldom change is arranged in the lower oil tank 3.During maintenance, as long as hang fuel-economizing case 1, just can overhaul being exposed to outer on-load voltage regulating switch 8 and high-voltage connection 9 places easily, dismantle low pressure outlet copper bar 4 and a large amount of bolts between the transformer body that stretch out lower oil tank 3 and the trouble that hangs out transformer body thereby saved.
