A kind of inductance for high-power DC power supply

Technical field

This utility model relates to a kind of inductance, particularly to a kind of inductance for high-power DC power supply.

Background technology

Inductance is typically made up of skeleton, winding, radome, encapsulating material, magnetic core or iron core etc..Specified electricity Flow a major parameter as inductance, refer to the maximum that inducer can bear under the working environment allowed Current value.The rated current of inductance is required higher by some high-power circuits, therefore occurs in that big electric current Inductance.

Heavy-current inductor specification has a variety of with shape both at home and abroad, but the inductance value of traditional heavy-current inductor is all Compare relatively low, most sensibility reciprocal be a few microhenry to tens microhenrys, the inductance that sensibility reciprocal reaches tens microhenrys is relative Fewer, henries up to a hundred the most less.

Utility model content

The purpose of this utility model is for the problems referred to above, it is provided that a kind of for high-power DC power supply Inductance, simple in construction, it is adaptable to high-power circuit, use safety.

The purpose of this utility model is achieved in that

A kind of inductance for high-power DC power supply, it is characterised in that include skeleton, coil, insulation Paper, some E type stalloys, some I type stalloys, four fixed supports and Copper Foil, described skeleton has One through cavity, described coil is wrapped on skeleton, and coil is coated with insulating paper, described some E The intermediate raised portion of type stalloy inserts from one end of skeleton cavity and fills up this cavity, some E type silicon The remainder of steel disc is then coated on outside skeleton, and described some I type stalloys are arranged at the skeleton cavity other end Outside, in connecting with the remainder of some E type stalloys skeleton being enclosed in, described some E types Stalloy and some I type stalloys are connected by four fixed support row, and described Copper Foil is along the bag of insulating paper Cover direction to be coated on outside four fixed supports.

Wherein, described coil uses the enamel covered wire coiling of one or more multi cord side by side.

Wherein, the two ends of one or more enamel covered wire described are stretched out outside skeleton respectively, and add stannum with flatiron The two ends of many enamel covered wires are merged respectively.

Wherein, the two ends of a described enamel covered wire or many enamel covered wires merge respectively two ends and copper Covered wire it is respectively welded on paper tinsel.

Wherein, described some E type stalloys are consistent with the orientation of some I type stalloys, mutually enter from Corner have fixing hole, described four fixed supports by the cooperation of screw and fixing hole by some E Type stalloy and some I type stalloys are clamped in center row and are connected.

Wherein, described insulating paper uses insulating tape to fix.

Wherein, described Copper Foil uses and is welded and fixed.

The beneficial effects of the utility model are: this utility model simple in construction, easy to make, it is adaptable to high Power circuit, and safety in utilization.

Detailed description of the invention

Below in conjunction with specific embodiments and the drawings, a step illustrates this utility model.

As Figure 1-Figure 4, a kind of inductance for high-power DC power supply, including skeleton 1, coil 2, insulating paper 3, some E type stalloys 4, some I type stalloys 5, four fixed supports 6 and copper Paper tinsel 7.Skeleton 1 has a through cavity 8.Coil 2 is wrapped on skeleton 1, coil 2 outsourcing Being covered with insulating paper 3, insulating paper 3 uses insulating tape to fix.The intermediate projections of some E type stalloys 4 Part inserts from one end of skeleton 1 cavity 8 and fills up this cavity 8, remaining of some E type stalloys 4 Part is then coated on outside skeleton 1.Some I type stalloys 5 are arranged at outside skeleton 1 cavity 8 other end Portion, connects with the remainder of some E type stalloys 4 in being enclosed in by skeleton 1.Some E type silicon steel Sheet 4 and some I type stalloys 5 are connected by four fixed support 6 row.Copper Foil 7 is along insulating paper 3 Cladding direction be coated on outside four fixed supports 6, and it is fixing to use welding to realize.

Coil 2 uses the enamel covered wire coiling of one or more multi cord side by side, with specific reference to voltage Fixed.The two ends of one or more enamel covered wire are stretched out outside skeleton 1 respectively, and add stannum by many paints with flatiron The two ends of copper-clad line merge respectively.In the two ends of an enamel covered wire or many enamel covered wires difference Covered wire 9 also it is respectively welded on the two ends merged and Copper Foil 7.

Some E type stalloys 4 are consistent with the orientation of some I type stalloys 5, mutually enter from four Angle has fixing hole 10, as shown in Figure 5 and Figure 6.Four fixed supports 6 are by screw 11 He It is solid that some E type stalloys 4 and some I type stalloys 5 are clamped in center row by the cooperation of fixing hole 10 Even.

This utility model simple in construction, easy to make, it is adaptable to high power circuit, and safety in utilization.
