Abstract

The utility model relates to a combined-type transformer comprising a cabinet. A high-pressure chamber, a low-pressure chamber and a measurement chamber are arranged in parallel in the front part of the cabinet; a capacitance compensating cabinet is arranged in the rear part of the cabinet; the transformer body is located among the capacitance compensating cabinet, the high-pressure chamber and the low-pressure chamber; the low-pressure chamber is provided with a switch cabinet; a connection cable between the switch cabinet and the capacitance compensating cabinet is arranged in a special cable groove at the bottom of the cabinet to avoid bareness. The combined-type transformer has reasonable layout of the internal structure in a side lead-out manner and has the advantages of small integral volume, high use ratio of the inside space, low investment cost and safe and reliable operation, and is particularly suitable for places in urban power distribution and garden landscape with particular requirement for the appearance of the transformer and the performance.

Description

A kind of combined transformer

Technical field

The utility model relates to the transformer technology field.

Background technology

Existing combined transformer mostly adopts following two kinds of outlet methods: one, front outlet side by side, promptly be that transformer body, hyperbaric chamber, low-pressure chamber (placing switch cubicle and capacitor compensation cabinet in it), measuring room are set up in parallel, the radiator of transformer be placed on the back side of transformer.This arrangement mode advantage is directly perceived, and all visual means all distribute in one direction, and are easy to operate; Shortcoming be the transformer overall volume big, take up room big, manufacturing cost is high, and metering indoor temperature height causes the gauge table misalignment easily and reduces useful life.Two, high and low pressure chamber and transformer body are established as a whole, the radiator of transformer is placed on the body volume of the back side minimizing combined transformer of transformer, and capacitor compensation cabinet, metering cabinet are placed on one independently in the casing in addition, be called measuring room, solved the shared space of measuring room and transformer and caused the high problem of temperature, connected with cable between low-pressure chamber and the measuring room.The cable that the shortcoming of this mode connects in the middle of being is longer, and exposed outside, easily by external stealing or sustain damage, shortened useful life.

The utility model content

The utility model is intended to solve existing low, the flimsy problem of the easy accuracy affected by environment of big, the inner measuring instrument of combined transformer overall volume.

For addressing the above problem, the technical scheme that the utility model is taked is: a kind of combined transformer is provided, comprise casing, front space is set side by side with hyperbaric chamber, low-pressure chamber and measuring room in the casing, back space is provided with capacitor compensation cabinet in the casing, and transformer body is between described capacitor compensation cabinet and hyperbaric chamber, low-pressure chamber.

Place switch cubicle in described low-pressure chamber, the connection cable between switch cubicle and the capacitor compensation cabinet is arranged in the client cables groove of bottom half.

Radiator is placed on described transformer body both sides, and corresponding casing two side positions have louvre.

Combined transformer described in the utility model is compared with existing like product, not only appearance design is attractive in appearance, and interior layout is rational in infrastructure, it is big to have space availability ratio, cost of investment is low, advantage safe and reliable to operation, it is specially adapted to urban network restructuring and garden landscape etc. to transformer profile and the higher place of performance requirement.

Fig. 3 is described combined transformer vertical view.

Embodiment

For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, each part of described combined transformer all is loaded in the casing 1, casing 1 is isolated into several spaces, and these several spaces comprise hyperbaric chamber 11, low-pressure chamber 12, measuring room capacitor compensation cabinet chambers 15 13 and a separate space 14 that is used to place transformer body.Hyperbaric chamber 11 is used to place the electric power incoming line that connects the external high pressure electrical network, and low-pressure chamber 12 is used to place switch cubicle, and measuring room 13 is used to place various measuring instruments.

When arranging, hyperbaric chamber 11, low-pressure chamber 12, measuring room 13 are listed in the leading space of casing 1, and capacitor compensation cabinet chamber 15 is positioned at casing 1 back space, the space of transformer body between capacitor compensation cabinet 15 and hyperbaric chamber 11, low-pressure chamber 12.Each space is separate, but mutually near.

In actual the use, for ease of maintenance maintenance is respectively installed in casing 1 inside, hyperbaric chamber 11, low-pressure chamber 12, measuring room 13, capacitor compensation cabinet chamber 15 all are provided with door, hyperbaric chamber 11, low-pressure chamber 12 open the door in casing 1 the place ahead, measuring room 13 opens the door in casing 1 side, and opens the door in casing 1 back in capacitor compensation cabinet chamber 15.And each indoor apparatus main body that needs observation, operation, all towards the door setting, for example each instrument all is arranged in the casing side in the measuring room 13, open the door as seen, therefore, strict, measuring room 13 is the lateral location that are positioned at low-pressure chamber 12.

Switch cubicle in the low-pressure chamber 12 and capacitor compensation cabinet 15 are connected by cable, and this cable is arranged in the cable trough 16 of casing 1 bottom, avoid cable to expose easy damaged or easily by the problem of stealing.Radiator 141 is placed on described transformer body 14 both sides, and 1 liang of side position of corresponding casing has louvre.
