Described screen is one whole or multistage Copper Foil or aluminium foil, multistage Copper Foil or aluminium foil adjacent position at regular intervals;
There is setting spacing distance insulating cylinder end, screen end; Insulating cylinder also comprises the ground strip being positioned at insulating cylinder main body, and ground strip welding is drawn; The contact position of ground strip and insulating cylinder bottom part body is provided with boss.
As a kind of execution mode of the present utility model, described ground strip is positioned at insulating cylinder main body.
The beneficial effects of the utility model are: the dry type phase-shifting rectifier transformer that the utility model proposes and insulating cylinder thereof, can overcome existing Transformer shielding layer and there is hidden danger, make easy and simple to handle, dependable performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model transformer insulating cylinder.
Fig. 2 is the other direction structural representation of the utility model transformer insulating cylinder.
Fig. 3 is the cutaway view of the utility model transformer insulating cylinder.
Accompanying drawing mark is as follows:
1: insulating cylinder main body 2: screen
3: ground strip 4: boss.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment one
Refer to Fig. 1 to Fig. 3, the utility model discloses a kind of dry type phase-shifting rectifier transformer, comprises insulating cylinder; Described insulating cylinder comprises insulating cylinder main body 1, is provided with screen 2 in the interlayer of insulating cylinder main body 1, and insulating cylinder main body 1 and screen 2 can be cured as one.
Described screen 2 is one whole or multistage Copper Foil or aluminium foil, multistage Copper Foil or aluminium foil adjacent position at regular intervals.
There is setting spacing distance insulating cylinder end, screen 2 end; Insulating cylinder also comprises ground strip 3 (ground strip 3 can be positioned at insulating cylinder main body 1), and ground strip 3 is drawn from insulating cylinder main body 1 by the mode of welding; Ground strip 4 is provided with boss 4 with the contact position bottom insulating cylinder main body 1, guarantees not leak copper.
Embodiment two
The difference of the present embodiment and embodiment one is, in the present embodiment, dry type phase-shifting rectifier transformer comprises: iron core column, insulating cylinder (structure can see the description of embodiment one), primary winding, secondary coil, the Support Level cake pectination stay (for supporting the pectination stay of secondary line astragal cake) be arranged at outside insulating cylinder.
Described primary winding, secondary coil are square copper pipe, and primary winding is positioned at inner side and adopts layered structure, and secondary coil is positioned at outside and adopts cake formula structure, is supported fixing by pectination stay.
Described primary winding is positioned at inner side, is mainly magnetic field energy by input side electric energy conversion, and secondary coil is positioned at the main electric energy that is converted into by magnetic field energy in outside and exports; Circuit part between primary winding and secondary coil and water route part are all separately independently, only there is electromagnetic field couples between primary winding and secondary coil, but internal circuit and water route two parts are one separately for primary winding and secondary coil.
Described primary winding comprises the first water route part, the first circuit part, and the first water route part multistage is in parallel, the first circuit part adopts multi-stage series structure.
Described secondary coil comprises the second water route part, second circuit part, secondary coil comprises some vice-side winding circuit, independent separately on each vice-side winding circuit and water route, be equipped with cooling passage in the line cake of each secondary coil, adopt and provide cooling water channel structure separately.
In the present embodiment, primary winding, secondary coil are around in line cake pectination stay; Transformer once, secondary coil adopts square copper pipe coiling, and copper pipe inside is used for cooling passage 2.
Because the total circle of transformer primary winding is longer, the flow velocity of cooling fluid
(k: coefficient, S: cross section of fluid channel amasss, L: the length of runner), in order to strengthen transformer water-cooled effect, primary winding adopts the multistage parallel connection of aspect, water route, circuit aspect adopts multi-stage series structure to realize.
Independent separately on each vice-side winding circuit of Circuit Fault on Secondary Transformer and water route, namely each line cake adopts and provides cooling water channel structure separately.
In sum, the dry type phase-shifting rectifier transformer that the utility model proposes, can overcome existing Transformer shielding layer and there is hidden danger, make easy and simple to handle, dependable performance.
Here description of the present utility model and application is illustrative, not wants by scope restriction of the present utility model in the above-described embodiments.Distortion and the change of embodiment disclosed are here possible, are known for the replacement of embodiment those those of ordinary skill in the art and the various parts of equivalence.Those skilled in the art are noted that when not departing from spirit of the present utility model or substantive characteristics, the utility model can in other forms, structure, layout, ratio, and to realize with other assembly, material and parts.When not departing from the utility model scope and spirit, can other distortion be carried out here to disclosed embodiment and change.
