Abstract
The utility model discloses a kind of big sections to combine paper-covered wire, including copper strap wire, interior insulation paper, external insulation paper and lining paper, it is coated with insulating layer on the outer surface of the copper strap wire and forms enameled wire, interior insulation paper bag is wrapped on enameled wire and forms paper covered wire unit, several paper covered wire elementary layers, which stack, to be set, and a lining paper is set between two adjacent paper covered wire units, external insulation paper bag is rolled in the outside of all paper covered wire units；The upper and lower end face of the lining paper is equipped with groove, and paraffin coating is equipped in groove.The utility model insulation effect is good, is suitable for the transformer use of super-pressure, large capacity, and lining paper layer will not increase the integral thickness of paper-covered wire, the paraffin coating on lining paper greatly improves insulation performance.
Description
Technical field:
The utility model relates to a kind of big sections to combine paper-covered wire.
Background technique:
Combine paper-covered wire be to be arranged by 2~4 paper covered wire or bare conductor by prescribed requirement, by specific insulating materials around
Winding wire made of packet is mainly used for oil-immersed type transformer, reactor and other electrical equipments.With motor, transformer, reactor
Etc. voltage class raising, the requirement to winding wire is also higher and higher.The combination paper bag of the prior art is conductive, due to each paper covered wire
Between without other insulated with material, so that its insulation performance is poor, be not able to satisfy the need that transformer develops to super-pressure, large capacity
It asks.
Summary of the invention:
The utility model is to provide a kind of big section combination paper bag in order to solve the above-mentioned problems of the prior art and lead
Line.
Technical solution used by the utility model has: a kind of big section combination paper-covered wire, including copper strap wire, interior insulation
Paper, external insulation paper and lining paper are coated with insulating layer on the outer surface of the copper strap wire and form enameled wire, and interior insulation paper bag is wrapped in
On enameled wire and paper covered wire unit is formed, several paper covered wire elementary layers, which stack, to be set, and is set between two adjacent paper covered wire units
A lining paper is set, external insulation paper bag is rolled in the outside of all paper covered wire units；
The upper and lower end face of the lining paper is equipped with groove, and paraffin coating is equipped in groove.
Further, the depth of the lining paper upper groove is 0.5-0.8mm.
Further, the paraffin coating with a thickness of 0.01-0.04mm.
Further, the insulating layer is polyester-imide paint layer.
The utility model has the following beneficial effects:
The utility model insulation effect is good, is suitable for the transformer use of super-pressure, large capacity, and lining paper layer not will increase
The integral thickness of paper-covered wire, the paraffin coating on lining paper greatly improve insulation performance.
Detailed description of the invention:
Fig. 1 is the utility model structure chart.
Fig. 2 is the structure chart of lining paper in the utility model.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 and Fig. 2, paper-covered wire is combined in a kind of big section of the utility model, including copper strap wire 1, interior insulation paper 2, outer
Insulating paper 3 and lining paper 4 are coated with insulating layer on the outer surface of copper strap wire 1 and form enameled wire, and interior insulation paper 2 is wrapped in enamel-cover
On line and paper covered wire unit is formed, several paper covered wire elementary layers, which stack, to be set, and is arranged one between two adjacent paper covered wire units
Lining paper 4, external insulation paper 3 are wrapped in the outside of all paper covered wire units.
Groove is equipped on the upper and lower end face of lining paper 4, paper covered wire unit is placed in groove, and paraffin coating is equipped in groove
41。
The depth of 4 upper groove of lining paper is 0.5-0.8mm.Paraffin coating 41 with a thickness of 0.01-0.04mm.
Insulating layer is polyester-imide paint layer, and interior insulation paper 2 is identical with the material of external insulation paper 3 in the utility model, is adopted
It is made of poly.
The utility model insulation effect is good, is suitable for the transformer use of super-pressure, large capacity, and lining paper layer not will increase
The integral thickness of paper-covered wire, the paraffin coating on lining paper greatly improve insulation performance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
