Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of have convenient production, Fast Installation winding, and be applicable to multiple output environment, and effectively improved production efficiency, improved the power transformer of the fault-tolerance going wrong in producing simultaneously.
A power transformer, includes winding skeleton, and described winding skeleton includes two sub-skeletons, described sub-skeleton is equipped with docking section, described docking section interconnects, and described sub-skeleton is equipped with inserted terminal with respect to the other end of docking section, and described inserted terminal is removably connected with the row of pegging graft.
Adopt above-mentioned design, winding skeleton is comprised of two identical sub-skeletons of structure, sub-skeleton can mutually dock and form winding skeleton, can make like this to produce winding skeleton more flexibly, conveniently, during with hour indicator winding processed, can coil respectively primary coil processed and secondary coil, in operation, finally again coiling be had together with the sub-skeleton combination of two of primary coil and secondary coil, form winding skeleton, can make like this dish system of winding skeleton more flexibly, conveniently.Avoided the low serious forgiveness of pipeline system operation, reduced the difficulty of doing over again, improved production efficiency, sub-skeleton is connected with inserted terminal with respect to the other end of docking section, inserted terminal is dismantled and is connected with the row of pegging graft, can there is the binding post of different grafting quantity or variable voltage that Plug pin patch bay meets transformer output requirement by selection like this, further improved practicality of the present utility model, main evaded being wholely set of traditional power transformer and the row of pegging graft, separated production process, has reduced owing to producing scrapping that error causes.
As setting of the present utility model, described grafting row is threaded with inserted terminal.
Adopt above-mentioned design, the row that pegs graft is threaded with inserted terminal and further supports the removably connect realization of mode of the row of pegging graft and inserted terminal.
As setting of the present utility model, the rectangular setting of the interface of described docking section, one end of described docking section is provided with hook, and the other end is provided with the hook groove that hook coordinates.
Adopt above-mentioned design, hook cooperatively interacts with groove, both can realize the docking between power transformer skeleton, and this class formation only has right-angle structure simultaneously, and mould manufactures convenient, fast.Install also very convenient simultaneously.
As setting of the present utility model, the junction of described connecting portion is mutually bonding.
Adopt above-mentioned design, projection and groove, by bonding, have improved the direct-connected tightness degree of sub-skeleton effectively, and sub-skeleton can not departed from mutually.
As setting of the present utility model, described winding skeleton also includes barricade, and described barricade is placed between two sub-skeletons in gap.
Adopt above-mentioned design, by the junction at two sub-skeletons, be provided with connecting plate, can between primary coil and secondary coil, form screen, prevent that high voltage channels in low-voltage, causes equipment to burn out when the insulating barrier of high-voltage coil and low-voltage coil destroys.
As setting of the present utility model, described barricade is provided with electrostatic screen layer.
Adopt above-mentioned design, prevent that the high pressure of primary coil can be induced to by space and parasitic capacitance the voltage of secondary coil, the low pressure microelectronic component for secondary coil constitutes a threat to like this.
Compared with prior art, the utility model has the advantage of, on the basis of the power transformer skeleton of symmetrical configuration, the grafting row who is originally wholely set is separated from skeleton, differentiation mould volume, be convenient to the production of mould, meanwhile, while having avoided in production process, due to the row of pegging graft, grafting pin to be installed, staff makes a fault, and causes whole power transformer skeleton integral body to be scrapped, further, easier for installation.
