Abstract
The present invention discloses a kind of method of using unsaturated polyester glass fibre Plastic Package coil.Be suitable for dry type mutual inductor, intermediate frequency transformer coil, dry-type transformer coil, the encapsulation of electric equipment products such as smoothing reactor.With its external insulation of electric equipment products in the past with poured with epoxy resin relatively, the precision height, volume is little, cost is low, simplified manufacturing process.Adopting the present invention to encapsulate production efficiency can improve greatly.
Description
The present invention relates to a kind of method of using electric equipment products such as unsaturated polyester glass fibre Plastic Package dry type mutual inductor.
Dry type mutual inductor cooperates electric current, voltage, the electric energy to circuit to measure with measuring instrument; Cooperate with protective relaying device electric power system and equipment are protected; And measuring instrument, protective relaying device and circuit high voltage are isolated, very high precision must be arranged.Its external insulation layer of dry type mutual inductor in the past adopts epoxy resin or doping cast, and the accuracy of manufacture is low, and loss is big, and qualification rate is low; And volume is big, the cost height.
The object of the present invention is to provide a kind of method of using electric equipment products such as unsaturated polyester glass fibre Plastic Package dry type mutual inductor, the dry type mutual inductor cost of cast encapsulation more in the past is low, the precision height; Method provided by the invention also is used to encapsulate electric equipment products such as intermediate frequency transformer coil, dry-type transformer coil, smoothing reactor except that being used to encapsulate the dry type mutual inductor.
Feature of the present invention is to use unsaturated polyester glass fibre Plastic Package coil by following operation: material metering, compression moulding or injection moulding or injection-compression molding, the demoulding, plucked technological process encapsulation, described unsaturated polyester glass fibre plastic material adopt D545 glass fiber plastic or DMC glass fiber plastic or PMC glass fiber plastic or BMC glass fiber plastic.
The present invention uses the external insulation layer attenuate that the overall encapsulation of unsaturated polyester glass fibre plastics makes instrument transformer, intermediate frequency transformer, dry-type transformer, smoothing reactor, bubble reduces in the insulating barrier, the heat dispersion height, volume is little, and mechanical strength improves, outer surface has the arc resistance energy, external insulation layer has the flame retarded energy, and technology of the present invention is simple, and production efficiency can improve greatly, cost is low, product precision height.
Now in conjunction with the accompanying drawings the present invention is described in further detail.
Fig. 1 is a process chart of the present invention;
Fig. 2 is a most preferred embodiment of the present invention.
Fig. 2 embodiment of the present invention is the instrument transformer that adopts the encapsulation of D545 glass fiber plastic: skeleton (1) is made with the D545 glass fiber plastic, primary winding (5) is on skeleton (1), become encapsulated layer (2) with the D545 glass fiber plastic then, encapsulated layer (2) becomes the skeleton of secondary coil (6), go up around last secondary coil (6) at encapsulated layer (2), outer shielding Copper Foil (4), make boss (7) in encapsulated layer (2) upper end then and be used for the location, the whole outer surface total encapsulated layer of D545 glass fiber plastic (3).With reference to Fig. 1, the D545 glass fiber plastic is pressed following operation: material metering, compression moulding or injection moulding or injection-compression molding, the demoulding, plucked technological process encapsulation.Carrying out external coating after the encapsulation handles.
Claims (2)
1, a kind of method of using unsaturated polyester glass fibre Plastic Package coil is characterized in that:
Use unsaturated polyester glass fibre Plastic Package coil and press following operation: material metering, compression moulding or injection moulding or injection-compression molding, the demoulding, plucked technological process encapsulation.
2, the method for application unsaturated polyester glass fibre Plastic Package coil according to claim 1 is characterized in that the unsaturated polyester glass fibre plastic material adopts D545 glass fiber plastic or DMC glass fiber plastic or PMC glass fiber plastic or BMC glass fiber plastic.
