A summary of the effect of refrigerants on varnished magnet wire is presented. The greatest effect on the motor materials is caused by absorption followed by desorption of refrigerants at higher temperatures. The high internal pressure of the absorbed refrigerants and the tendency of these refrigerants to evolve from the materials results in blisters, cracks and internal bubbles in the varnish and magnet wire insulation. The degradation of the insulation results in changes in the bond, dielectric and burnout strength of the varnished magnet wire. Desorption of HCFC-22, and to a lesser extent HFC-32, HFC-134 and HFC-152a, has the greatest effect on insulation integrity. Of the refrigerants tested, exposure to HCFC-22 produces the most deleterious effects on the magnet wire insulation and varnishes.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114219845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The capacitors are characterized in terms of their capacitance stability and dielectric loss in the frequency range of 50 Hz to 100 kHz at temperatures of 20/spl deg/C to 200/spl deg/C. DC leakage current measurements are also obtained as a function of temperature. The effects of thermal stressing, in air and without electrical bias, on the properties of the capacitors are determined as a function of thermal aging up to 12 weeks. The results indicated that short-term aging has minimal influence on the dielectric properties of both the teflon and ceramic type capacitors.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121788459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data used are the result of four decades spent in designing, using and observing magnet processing systems. Most information has been gleaned from empirical studies and results. A re-evaluation of magnet processing instrumentation prompts the investigation of matching the processing fixture to the instrument for optimum energy transfer. Factors which must be considered in designing or specifying a magnetizer or conditioner are: the magnet material and its coercive force; the size of the entire magnet assembly; the location of the magnet in the assembly; the type and size of the assembly materials other than the permanent magnets; the polar configuration of the assembly; and production speed required.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131378763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A silane copolymer compound with 28% thermal black filler is shown to retain its melt flow rate by 90% when stored for a year at 23/spl deg/C and 55% relative humidity. Cables of filled silane copolymer insulation are cured at 90/spl deg/C in water, and at ambient temperature and humidity conditions. Equivalent properties are achieved whether the fillers are fully compounded with the copolymer or used in the form of a masterbatch. The extruded flame retardant cables are shown to have the fillers well dispersed in the polymer insulation to yield optimum flammability, tensile and dielectric properties. Statistical methods are used to compare the dielectric performance before and after a mechanical impact. The advantages and disadvantages of the silane copolymer technology over peroxide and radiation cross-linking technologies are discussed.","PeriodicalId":428411,"journal":{"name":"Proceedings of Electrical/Electronics Insulation Conference","volume":"33 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131613241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
