Abstract

The utility model discloses a two-in-one transformation rectifying device used for converting alternating current to direct current. The two-in-one transformation rectifying device used for converting alternating current to direct current includes a rectifier and a transformer installed in an oil tank of the transformer. The rectifier is disposed in the oil tank of the transformer and is disposed in a low-voltage side of the transformer. The transformer is connected with the rectifier through a bus copper bar. The two-in-one transformation rectifying device provided by the utility model has advantages of reducing enterprise production cost, reducing equipment size and reducing energy consumption.

Description

Two-in-one transformation rectifying device

Technical field

The utility model relates to the technical field that transformer and rectifier combine.

Background technology

At present alternating current is become in the galvanic commutation system, mainly by independently be arranged at the transformer in the oil tank of transformer and independently be arranged at two in the outer rectifier of oil tank of transformer independently product form, pass through the connection of bus copper bar between the two.There is following shortcoming in above-mentioned commutation system: on the one hand, because transformer low voltage is to be drawn out to outside the oil tank of transformer in oil tank of transformer by the busbar copper bar, be alternating current because of what in the busbar copper bar, pass through again, in busbar copper bar and fuel tank iron-clad, easily produce very big spuious energy losses such as eddy current like this; On the other hand, traditional transformer and the distance between the rectifier are longer, and the length of bus copper bar that causes connecting both is corresponding elongated, and this has further increased the loss in the bus copper bar, and the long bus copper bar of length has also increased the production cost of enterprise.

The utility model content

The purpose of this utility model provides a kind ofly can reduce enterprise's production cost, reduce equipment volume, reduce the two-in-one transformation rectifying device of energy consumption.

For achieving the above object, the utility model has adopted following technical scheme: described two-in-one transformation rectifying device, comprise: rectifier, and be installed on transformer in the oil tank of transformer, wherein, rectifier is arranged in the oil tank of transformer and is positioned at low pressure one side of transformer, and transformer is connected by the bus copper bar with rectifier.

By the enforcement of technique scheme, the utlity model has the advantage that can reduce enterprise's production cost, reduce equipment volume, reduce energy consumption.

Description of drawings

Fig. 1 is the structural representation of two-in-one transformation rectifying device described in the utility model.

Fig. 2 is the annexation schematic diagram between transformation rectifying device shown in Fig. 1 and AC power, the load.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 1, shown in Figure 2, described two-in-one transformation rectifying device, comprise: rectifier 1, and be installed on transformer 3 in the oil tank of transformer 2, rectifier 1 is arranged in the oil tank of transformer 2, and be positioned at the low-pressure side of transformer 3, be connected by bus copper bar 4 between rectifier 1 and the transformer 3, in actual applications, the input of transformer 3 also is connected by the bus copper bar with AC power 5, the output of rectifier 1 also is connected with load 6 by the bus copper bar, when the busbar copper bar leads to the output of rectifier 1 load 6 outside the oil tank of transformer 2, because what passed through on the busbar copper bar this moment is the direct current that obtains through after rectifier 1 rectification, energy loss with regard to having avoided in this busbar copper bar and oil tank of transformer 2 iron-clads, producing because of eddy current like this, and since rectifier 1 near transformer 3, and be arranged in same oil tank of transformer 2, distance between the two is very short, and then the length of bus copper bar that connects both is corresponding very short, so not only greatly reduce energy loss, also reduced enterprise's production cost, dwindled equipment volume.

Claims

1. two-in-one transformation rectifying device comprises: rectifier, and be installed on transformer in the oil tank of transformer, it is characterized in that: rectifier is arranged in the oil tank of transformer and is positioned at low pressure one side of transformer, and transformer is connected by the bus copper bar with rectifier.
