Abstract

The utility model discloses a novel combined transformer which comprises a high pressure chamber, a low pressure chamber and a transformer chamber which are of a combined structure shaped like a Chinese character 'pin'. A rear oil tank and a transformer body are arranged in the transformer chamber, the transformer body is placed in the rear oil tank, and the tank bottom of the rear oil tank is designed to be lifted. A load switch and a plug-in type fuse are arranged above the rear oil tank, the plug-in type fuse is horizontally arranged above the transformer body, and a fin type radiator is fixedly mounted on the rear side of the transformer chamber. A high pressure sleeve tube and a tapping switch are arranged in the high pressure chamber, the tapping switch is arranged on the connecting portion of the high pressure chamber and the transformer chamber, a low pressure cabinet and a low pressure sleeve tube are arranged in the low pressure chamber, and the low pressure sleeve tube is connected with the transformer body through a low-voltage lead copper bar. According to the novel combined transformer, the structure is optimized, the tank bottom of the rear oil tank is lifted upwards, namely the height of the oil level of the transformer is lowered, the space of the oil tank of the transformer is reduced, the oil consumed amount of the transformer at the lifted height can be reduced, meanwhile, the length of a low voltage led-out line is reduced, and the load loss of the transformer is correspondingly reduced.

Description

A kind of New Type Combinational Transformer

Technical field

The utility model relates to combined transformer and manufactures field, relates in particular to a kind of New Type Combinational Transformer.

Background technology

Combined transformer is a kind of the High-Voltage Electrical Appliances such as plug-in type fusible link, backup fuse, oil-immersed load switch, no-excitation voltage regulating tap switch to be all contained in to the electric equipment in oil tank of transformer as the parts of transformer.General combined transformer divides transformer room, hyperbaric chamber, low-pressure chamber; many finished products font structure is arranged; because high-pressure side is by pluggable all insulation elbow cable end inlet wire; low-pressure side is installed different transmission line circuits and corresponding protective device and measuring instrument according to user's request; therefore combined transformer is multiple functional, compact conformation, is widely used in the electricity consumption places such as city illumination, residential quarter, factory, construction.Combined transformer before, transformer room is owing to being subject to the restriction of low-pressure line-outgoing side case, must arrange fuel tank size according to low-pressure chamber scheme, therefore often transformer room does greatlyr, transformer oil consumption and other materials consumption often produce unnecessary waste and cost increases

Utility model content

For the problems referred to above, the New Type Combinational Transformer that the utility model provides a kind of reasonable in design, reduced transformer oil consumption, reduces production costs.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of New Type Combinational Transformer, comprise the hyperbaric chamber that is isosceles triangle combining structure, low-pressure chamber and transformer room, wherein low-pressure chamber is positioned at right side, hyperbaric chamber, transformer room is positioned at hyperbaric chamber and the middle rear side of low-pressure chamber, in described transformer room, be provided with rear fuel tank and transformer body, transformer body is placed in rear fuel tank, at the bottom of the case of described rear fuel tank, raise design, described rear fuel tank top is provided with on-load switch and plug-in fuse, plug-in fuse horizontal arrangement is above transformer body, described transformer room rear side is installed with finned radiator, in described hyperbaric chamber, be provided with bushing, shunting switch, described shunting switch is located at hyperbaric chamber and junction, transformer room, in described low-pressure chamber, be provided with low-voltage cabinet and low-tension bushing, described low-tension bushing is connected with transformer body by low-voltage lead copper bar.

Further, on the rear fuel tank in described transformer room, be also provided with thermometer, pressure vacuum gauge, oil filler plug, oil level gauge and pressure relief valve.

Further, described in, raising height at the bottom of the case of rear fuel tank of design is 20-30cm.

From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage:

The utility model is upwards raised at the bottom of by rear fuel tank case, be that transformer oil level height reduces, oil tank of transformer space diminishes, can reduce the transformer oil consumption of raise height, reduce low pressure length of lead-out wire simultaneously, reduce accordingly the load loss of transformer, made Combined transformer structure optimization fall this, improved productivity effect.
