Abstract

The utility model provides an electroslag furnace transformer which comprises a transformer oil tank, a high voltage sleeve, a lead for connecting a head end and a tail end and a lead for connecting a led-out end, wherein the transformer oil tank is connected with a top connecting point of an electroslag furnace through the lead for connecting a head and a tail ends, the transformer oil tank is connected with a side connecting point of the electroslag furnace through the lead for connecting the led-out end, the upper end of the transformer oil tank is provided with a head projecting end and a tail projecting end of a low voltage coil, the side of the transformer oil tank is provided with a middle led-out end of the low voltage coil, the lead for connecting a head and a tail ends is connected to the head and the tail projecting ends of the low voltage coil, and the lead for connecting a led-out end is connected to the middle led-out end of the low voltage coil. The utility model has the advantages that through improvement on the structure of the existing electroslag furnace transformer, the position of the middle led-out end of the low voltage coil is changed from the top end to the side end, so that the length of the connecting leads can be reduced, and the installation cost of the whole equipment is reduced.

Description

A kind of electroslag furnace is used transformer

Technical field

The utility model relates to the electric equipment fitting field, and particularly a kind of electroslag furnace is used transformer.

Background technology

The employed transformer adopting bipolar electrode of present big-and-middle-sized electroslag furnace formula transformer; Its upper end be connected to two electrodes, intermediate point connects the electroslag furnace furnace bottom, thus transformer as shown in Figure 1 be from the top; Because three leading-out terminals of coil are all drawn in the top; And the low-voltage coil intermediate point need connect furnace bottom, therefore can increase the length of the lead-in wire of cabling on cable rack, and then increase this more cost and loss of equipment greatly.

The utility model content

To above problem; The utility model is used transformer through a kind of electroslag furnace of design, existing transformer connection end position is improved accordingly, thereby can reduce the length that connects lead-in wire; Practice thrift equipment cost; For reaching this purpose, the utility model provides a kind of electroslag furnace to use transformer, comprises that oil tank of transformer, bushing, two ends connect lead-in wire and are connected lead-in wire with exit; Said oil tank of transformer connects lead-in wire through two ends and links to each other with the top contact of electroslag furnace; Said oil tank of transformer connects lead-in wire through exit and links to each other with the sidepiece contact of electroslag furnace, and said oil tank of transformer upper end is provided with low-voltage coil head and the tail external part, and the oil tank of transformer side is provided with low-voltage coil middle part exit; Said two ends connect lead-in wire and are connected on the low-voltage coil head and the tail external part, and said exit connects lead-in wire and is connected on the exit of low-voltage coil middle part.

Further improvement as the utility model; Said low-voltage coil head and the tail external part separately is arranged on transformer oil box top or head end electrode and tail end electrode integral body by head end electrode and tail end electrode and is arranged on the transformer oil box top; The head end electrode of this patent low-voltage coil head and the tail external part and tail end electrode can be concentrated and be arranged on the transformer oil box top and also can separately be arranged on the transformer oil box top, and producer can select as required accordingly.

The utility model changes exit position, low-voltage coil middle part into side by the top, thereby can reduce the length that connects lead-in wire through existing electroslag furnace is improved with transformer device structure, reduces the installation cost of entire equipment.

Embodiment

Below in conjunction with accompanying drawing and embodiment utility model is done detailed explanation:

The utility model is used transformer through a kind of electroslag furnace of design, existing transformer connection end position is improved accordingly, thereby can reduce the length that connects lead-in wire, practices thrift equipment cost.

As a kind of specific embodiment of the utility model; The utility model provides connection sketch map a kind of electroslag furnace as shown in Figure 2 to use transformer; Comprise that oil tank of transformer 1, bushing 2, two ends connect lead-in wire 3 and be connected with exit and go between 4; Said oil tank of transformer 1 connects lead-in wire 3 through two ends and links to each other with the top contact 5-1 of electroslag furnace 5, and said oil tank of transformer 1 connects lead-in wire 4 through exit and links to each other with the sidepiece contact 5-2 of electroslag furnace 5, and said oil tank of transformer 1 upper end is provided with low-voltage coil external part 1-1 from beginning to end; The head end electrode of this patent low-voltage coil head and the tail external part 1-1 and tail end electrode can be concentrated and be arranged on oil tank of transformer 1 top and also can separately be arranged on oil tank of transformer 1 top; Producer can select as required accordingly, and oil tank of transformer 1 side is provided with low-voltage coil middle part exit 1-2, and said two ends connect lead-in wire 3 and are connected on the low-voltage coil head and the tail external part 1-1; Said exit connects lead-in wire 4 and is connected on the exit 1-2 of low-voltage coil middle part; This patent can significantly reduce the length that connects lead-in wire through changing exit 1-2 position, low-voltage coil middle part into side by the top, reduces the installation cost of entire equipment.

The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
