Description

Integrated transformer

Technical field

The utility model is specifically related to a kind of integrated transformer.

Background technology

As everyone knows, the major function of transformer is adjustment electrical power trans mission/distribution system being carried out to ascending, descending voltage, standard compliant voltage of power is delivered to next stage distribution system or terminal use.Those skilled in the art should know, on existing market is column-type transformer comparatively widely, this transformer generally comprises transformer room, low-voltage cabinet, power cable high-pressure side in power distribution network is often all mounted in the HV Terminal above transformer-cabinet, then insulator is passed through, again via transformer pressure-reducing, be connected to low-voltage cabinet by the low-voltage terminal of transformer room and be fed to away by external outgoing line busbar on low-voltage cabinet, obviously, in this transformation process, due on the high-pressure side of power cable and insulator and low-voltage cabinet outgoing line busbar all outside exposed, not only easily affect equipment performance because of the severe of weather, very easily cause the potential safety hazards such as electric shock casualty accident especially, and in monitoring and maintenance, also create inconvenience.

Summary of the invention

The purpose of this utility model is the defect overcoming prior art, a kind of reliable and stable, integrated transformer that fail safe is high is provided, this integrated transformer, as the improvement upgraded product of column-type transformer, can easily carry out built on stilts installation and installation of landing on concrete column.

Realize above-mentioned purpose, the utility model adopts a kind of integrated transformer, comprise hyperbaric chamber, transformer room and low-pressure chamber, described low-pressure chamber comprises low-temperature measurement room, low tension room and low pressure feeder line room, very touch-type cable joint is provided with in described hyperbaric chamber, described very touch-type cable joint comprises insulating sleeve, stress cone, crimp type terminal and plug bar, described insulating sleeve has outer shielding layer from outside to inside respectively, EPDM insulating barrier and equalizing press layer, this insulating sleeve structurally forms longitudinal inlet wire pipe and transverse splicing pipe, the top of described crimp type terminal forms screw, this crimp type terminal is arranged in described longitudinal inlet wire pipe, its top screw is in described transverse splicing pipe, described stress cone is arranged on the below week side position of described crimp type terminal, described plug bar is formed with described screw and is threaded.

Preferably, in the utility model, this very touch-type cable joint can be preferably T-type structure or elbow-type structure, i.e. the T-shaped cable joint of very touch-type or very touch-type elbow-type cable joint.

Preferred further, in the utility model, when the T-shaped cable joint of use very touch-type, the end-position of transverse splicing pipe can arrange lightning arrester easily.

Preferred further again, be provided with outgoing line busbar in described low-pressure chamber, this outgoing line busbar and external environment are in closing isolation.

By the above-mentioned improvement to prior art, integrated transformer of the present utility model has following beneficial effect: first, owing to the high-pressure side of power cable directly to be accessed the tangible T-shaped cable joint be arranged in hyperbaric chamber, make the high-pressure side of power cable be completely enclosed within hyperbaric chamber, outside environmental elements is difficult to have influence on integrated transformer performance of the present utility model; Secondly, the main material of the insulating sleeve of very touch-type cable joint of the present utility model is made up of EPDM (ethylene propylene diene rubber) insulating barrier, this kind of material has superior electrical insulating property and corona resistance and resistance to ag(e)ing, therefore the insulating sleeve that this material is formed has tangible property, greatly facilitates staff and carries out installing, monitors and the operation such as maintenance; Then, the outgoing line busbar of low-pressure side has been arranged in low-pressure chamber by the utility model completely, defines effective isolation with outside environmental elements, and therefore, its safety and stability is protected further; Finally, very touch-type cable joint tail end of the present utility model also can arrange lightning arrester, and its stability is optimized further.
