Abstract

The utility model relates to a self-adhesive glass wire wrapped mica tape wrapped wire. A mica tape is wrapped on a copper flat wire (1) or a glass wire copper-clad flat wire to form the self-adhesive glass wire wrapped mica tape wrapped wire. The self-adhesive glass wire wrapped mica tape wrapped wire comprises the mica tape (2) wrapped on the surface of the copper flat wire (1). Adhesive agent (3) is arranged at the surface of the mica tape (2). The glass wire (4) is wrapped at the surface of the adhesive agent (3). Self-adhesive resin (5) is arranged at the surface of the glass wire (4). The utility model has the advantages that labour and time are saved, the self-adhesive glass wire wrapped mica tape wrapped wire is insulated and can resist heat, the performance for resisting corona is good, etc. The self-adhesive glass wire wrapped mica tape wrapped wire can be directly used for coils used for winding a high pressure motor.

Description

Self-adhesive glass wire wrapped mica tape wrapped wire

The utility model relates to a kind of tack glass fiber bag mica tape lapped wire, especially for the stator coil of all kinds of high-voltage motors of coiling.

At present, the coil of high-voltage motor generally adopts copper strap wire or the coiling of glass fiber copper-clad lenticular wire with lapped wire, and at its wrapped glass fiber mica tape in outside, to solve Insulation Problems, but not only there is the excessive shortcoming of thickness of insulating layer in this structure, and because the coil shape complexity, must be by manual wrapped glass fiber mica tape, so that it is solution turn-to-turn insulation, time-consuming like this, easily break the insulating barrier of coil; Also have, the coil of said structure is heat-resisting, corona-resistance property is relatively poor.

The purpose of this utility model is that a kind of saving of work and time, insulation, heat-resisting and tack glass fiber bag mica tape lapped wire that corona-resistance property is good will be provided.

The purpose of this utility model is achieved like this, existing lapped wire wrapped glass fiber mica tape on copper strap wire (1) or glass fiber copper-clad lenticular wire forms, now done improvement, it comprises the wrapped mica tape (2) in copper strap wire (1) surface, add adhesive (3) on the surface of mica tape (2), the surperficial wrapped glass fiber of adhesive (3) (4) adds tack resin (5) on glass fiber (4) surface.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is a structure chart of the present utility model.

Mica tape of the present utility model (2) Ping Bao or stacked package one deck or two layers are on copper strap wire (1), to guarantee to obtain various required insulation thicknesses.When mica tape (2) wrapped after copper strap wire (1) is gone up by wrapped machine, at its surperficial coating adhesive (3), bonding in order between mica tape (2) and copper strap wire (1).

Glass fiber of the present utility model (4) also can be other heat resistance fibers, bilayer or individual layer are wrapped on the surface of adhesive (3), and interlayer adds coating adhesive (3), in order to ply adhesion, be coated with tack resin (5) on glass fiber (4) surface then, form product after cure rolling.Sticking during this lapped wire room temperature, can be adhesion-molded voluntarily during high temperature, can be directly used in the coil of coiling high-voltage motor.

The utility model is because after having adopted said structure, insulation property have been improved, owing to used mica tape (2), heat-resisting (thermal endurance class can reach 155 ℃ of F levels), corona-resistance property have been improved, can be directly used in the coil of coiling high-voltage motor, need not be again by removing to hold turn-to-turn insulation layer, saving of work and time by hand.

Claims

1, a kind of tack glass fiber bag mica tape lapped wire, form by wrapped glass fiber mica tape on copper strap wire (1) or the glass fiber copper-clad lenticular wire, it is characterized in that it comprises the wrapped mica tape (2) in copper strap wire (1) surface, add adhesive (3) on the surface of mica tape (2), the surperficial wrapped glass fiber of adhesive (3) (4) adds tack resin (5) on glass fiber (4) surface.

2, tack glass fiber bag mica tape lapped wire according to claim 1 is characterized in that mica tape (2) Ping Bao or stacked package one deck or two layers are on copper strap wire (1).
