Abstract
The invention 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.Insulation effect of the present invention 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 present invention 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, it is wrapped by specific insulating materials and
At winding wire, be mainly used for oil-immersed type transformer, reactor and other electrical equipments.With electricity such as motor, transformer, reactors
The raising of grade is pressed, the requirement to winding wire is also higher and higher.The combination paper bag of the prior art is conductive, due between each paper covered wire
Without other insulated with material, so that its insulation performance is poor, it is not able to satisfy the demand that transformer develops to super-pressure, large capacity.
Summary of the invention：
The present invention is to provide a kind of big section combination paper-covered wire to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：Paper-covered wire is combined in a kind of big section, 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 paint
On envelope curve and paper covered wire unit is formed, several paper covered wire elementary layers, which stack, to be set, and is arranged between two adjacent paper covered wire units
One lining paper, external insulation paper bag are 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 present invention has the advantages that：
Insulation effect of the present invention is good, is suitable for the transformer use of super-pressure, large capacity, and lining paper layer will not increase paper bag and lead
The integral thickness of line, the paraffin coating on lining paper greatly improve insulation performance.
Detailed description of the invention：
Fig. 1 is structure of the invention figure.
Fig. 2 is the structure chart of lining paper in the present invention.
Specific embodiment：
The present invention will be further described below with reference to the drawings.
Such as Fig. 1 and Fig. 2, the present invention combines paper-covered wire, including copper strap wire 1, interior insulation paper 2, external insulation in a kind of big section
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 on enameled wire
And paper covered wire unit is formed, several paper covered wire elementary layers, which stack, to be set, and a lining paper is arranged between two adjacent paper covered wire units
4, external insulation paper 3 is 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 present invention, is all made of poly-
Mpd-i is made.
Insulation effect of the present invention is good, is suitable for the transformer use of super-pressure, large capacity, and lining paper layer will not increase paper
The integral thickness of packet conducting wire, the paraffin coating on lining paper greatly improve insulation performance.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
