Description
Technical field
The present invention relates to charging pile technical fields, and in particular to a kind of intelligent electric charging pile transformer.
Background technology
Charging pile can be fixed on ground or wall, be installed on public building (public building, market, Public Parking etc.)
In residential area parking lot or charging station, it can be charged according to the electric vehicle that different voltage class is various models.It fills
The input terminal of electric stake is directly connected to AC network, output end be equipped with charging plug for for electric vehicle charging.
Transformer is used for a long time in open-air atmosphere, can lead to major insulation aging after the bushing water inlet in transformer,
Dielectric level reduces；Breakdown voltage of transformer oil is relatively low；Or caused by other failure propagations, as winding has turn-to-turn short circuit or ground connection
When failure, since electric arc and the copper melted (aluminium) particle four are dissipated and splashed, so that accident sprawling is expanded, develop into phase fault.Or
It is to overheat since conducting wire interior welds are bad and fuse or blown because of turn-to-turn short circuit, and winding caused by short-circuit stress is rolled over
It is disconnected.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple structure and reasonable design, make
With a kind of convenient intelligent electric charging pile transformer.
To achieve the above object, the technical solution adopted by the present invention is：It include transformer body, gasket, oiling chamber,
Oil filler point, oil fill plug, sleeve, pin, bushing, copper cap, pigtail splice, terminal plate；The transformer body upper end
Bushing periphery be provided with gasket, oiling chamber is provided between gasket and transformer body, is provided on gasket
The oil filler point communicated with oiling chamber, oil filler point upper end are provided with oil fill plug；The gasket center is inserted with sleeve, high pressure
Casing is plugged in sleeve, and bushing passes through pin connection with sleeve；Copper cap, high pressing sleeve are provided on the bushing
Pigtail splice in pipe is connect with terminal plate circuit.
Preferably, the bottom of the bushing is fixed by screw and spring washer with gasket.
Preferably, the copper cap upper end is fixed with pressing plate, pigtail splice is fixed by bolt and spring washer with pressing plate.
Preferably, the gasket is fixed by screws with transformer body.
When the present invention operates, by oil fill plug to the oiling chamber oiling between transformer body and gasket, high pressing sleeve
Oil sealing is formed between the bottom and transformer body of pipe, copper cap is stamped in the upper end of bushing, and is pierced by pigtail splice, is pierced by
There are above hole pressing plate, guarantee not to intake, spring washer enhances tightness, makes between copper cap and gasket, gasket and transformer
