Abstract
The utility model discloses a high temperature ceramic electromagnetic wire comprising a copper wire core whose outer portion is packed with an antioxygen layer and a lacquer coating. The outer portion of the antioxygen layer and the lacquer coating layer is packed with a high-temperature resistant insulation layer. The utility model is characterized in that the high-temperature resistant insulation layer comprises a mica tape coiling layer coiled on the outer portion of the antioxygen layer and the lacquer coating and a glass wire tape coiled on the outer portion of the mica tape coiling layer or a coiling layer of the glass wire tape and the synthetic fiber wire tape of high-temperature resistant. The two surfaces of the coiling layer of the glass wire tape and the synthetic fiber wire tape of high-temperature resistant are high-temperature ceramic lacquer coatings. The gap of the glass wire tape or the coiling layer of the glass wire tape and the synthetic fiber wire tape of high-temperature resistant is filled with high-temperature ceramic lacquer. The insulation layer of the electromagnetic wire is improved. The thermal endurance class, the ageing resistance, the mechanical strength, the voltage resistance, the corona resistance, the insulation performance and the radiation resistance of the electromagnetic wire are greatly improved.
Description
Technical field: the utility model Refractory Ceramic Electromagnetic Wire is the super heat-resisting resistant to elevated temperatures ceramic character insulation coated electricity layer electromagnetic wire that belongs to the electromagnetic wire class, 300-450 ℃ of its temperature resistant grade.
Background technology: existing electromagnetic wire is pressed the high F level of temperature resistant grade heatproof (155 ℃), H level (180 ℃), C level (220 ℃), the utility model relates to a kind of super heat resistant ceramic electromagnetic wire and ceramic insulation lacquer, after outside copper core, carrying out anti-oxidant treatment, twine with heat-resisting mica and to form heat-resisting insulating barrier and be adhesively fixed.This improvement that the insulating barrier of electromagnetic wire is carried out, improved the thermal endurance of electromagnetic wire, but grade F level (155 ℃), H level (180 ℃), C level (220 ℃), the general resin of mica is adhesively fixed, to ageing-resistant performance and mechanical strength, anti-corona of proof voltage and insulation property, radiation resistance all do not reach the requirement of higher temperature yet.
Summary of the invention:
The purpose of this utility model is exactly further to improve electromagnetic wire resistance and high temperature resistance property and corresponding other performances of canned pump, provides a kind of thermal endurance class to reach the electromagnetic wire of 300 ℃-450 ℃ canned pump.
Refractory Ceramic Electromagnetic Wire of the present utility model, be that copper core is surrounded by antioxygen layer outward and hangs enamelled coating, antioxygen layer and extension enamelled coating layer are surrounded by temperature-resistant insulation layer outward, it is characterized in that: temperature-resistant insulation layer is by being wrapped in antioxygen layer and hanging the outer mica tape winding layer of enamelled coating and be wrapped in mica tape winding layer outer glass tape or glass tape and resistant to elevated temperatures synthetic fibers silk ribbon winding layer, glass tape or glass tape and resistant to elevated temperatures synthetic fibers silk ribbon winding layer two sides are the refractory ceramics lacquer coat, and the refractory ceramics lacquer is being filled in glass tape or glass tape and resistant to elevated temperatures synthetic fibers silk ribbon winding layer gap.Insulating barrier to electromagnetic wire in the utility model has carried out new improvement, has improved the thermal endurance class (300 ℃-450 ℃) of electromagnetic wire greatly, ageing-resistant performance and mechanical strength, and anti-corona of proof voltage and insulation property, radiation resistance all improves greatly.Make shielded electric pump than original shielded electric pump product by this electromagnetic wire, the bigger raising of its heat resistance.Improve resistance to ag(e)ing simultaneously and have characteristics such as longer service life.The mica tape winding layer be by glass fiber strap one side bonding mica sheet constitute, the organic silicon high-temperature pottery coats with lacquer adhesive linkage between mica sheet and the glass fiber strap.Mix in the organic siliconresin and be added with one or more metal oxide pigments and extender pigment.Metal oxide pigment and extender pigment can be mica powder, flake asbestos, talcum powder, kaolin, zinc white, titanium dioxide, aluminium oxide powder, silicon powder (being silicon dioxide powder) bentonite, low melting point (300-450 ℃) glass dust or ceramic powder.Desired granularity is preferably between the 800-1250 order.
The utility model compared with the prior art, insulating barrier to electromagnetic wire in the utility model has carried out new improvement, improved the thermal endurance class (300 ℃-450 ℃) of electromagnetic wire greatly, ageing-resistant performance and mechanical strength, the anti-corona of proof voltage and insulation property, radiation resistance all improve greatly, make shielded electric pump than original heat-resisting shielded electric pump product by this electromagnetic wire, its heat resistance has had bigger raising.While has also improved the resistance to ag(e)ing of pump and has made the longer service life of pump.
Description of drawings: accompanying drawing has been represented a kind of Refractory Ceramic Electromagnetic Wire structural representation of the present utility model, further specifies the utility model below in conjunction with the example of accompanying drawing.
Specific embodiment: this Refractory Ceramic Electromagnetic Wire of the present utility model has: copper core 1, antioxygen layer and extension refractory ceramics enamelled coating 2, mica tape winding layer 3, refractory ceramics lacquer coat 4, glass tape or glass tape and resistant to elevated temperatures synthetic fibers silk ribbon winding layer 5, refractory ceramics lacquer coat 6.The mica tape of mica winding layer is mica paper and glass wool cloth, is bonded with high temperature resistant organosilicon pottery lacquer, and thickness is 0.1m/m, and wide 6m/m is longer than the high time of fire prevention mica tape heatproof that the open market is used.The glass fiber winding layer has and does not take off double glass fiber band or the single glass fibre band of touching agent wax and so on for (1) alkali-free, and perhaps (2) do not have wax glass fiber and resistant to elevated temperatures synthetic fibres by alkali-free and mix silk ribbon in what 1: 1 ratio was formed, but Dan Keshuan.Described refractory ceramics lacquer is according to the heatproof requirement, machine silicones by two kinds of trades mark of organic siliconresin is formed, adding one or more following metal oxide pigments and extender pigment more therein mixes, make itself and organic siliconresin form the Chemical Physics reaction, in the organic siliconresin structural formula, introduce inorganic group, introduce different its heatproof of inorganic group structure and anti-aging, efflorescence, the be full of cracks performance is different, can be made into the ceramic insulation enamelled coating of high temperature resistant grade of various differences and different mechanical performances, satisfying different heatproofs requires and other performance requirements, add metal oxide pigment and extender pigment kind and be selected from following any three kinds: mica powder, flake asbestos, talcum powder, kaolin, zinc white, titanium is from powder, aluminium oxide powder, silicon powder (being silicon dioxide powder) bentonite, low melting point (300-450 ℃) glass dust and ceramic powder etc., granularity requirements 1200 orders.
