Information × Registration Number 0210U006893, 0108U010895 , R & D reports Title Research of electrophysica features of capacitor insulation from domestic polipropilen film and possibility of the creation highvoltage capacitor alternating current popup.stage_title Head Rudakov Valerij, Registration Date 21-12-2010 Organization The Kharkov state polytechnical university popup.description2 The problem of creation of power high-voltage capacitors of a alternating current is considered. Distribution of an electrical field at edges elektrods are determined by numerical methods of the integral equations for raking and rounding form of edge with the account many dielectric layers with different dielectric constant. The reliability and accuracy of calculations of the received results is proved. It is offered tasks with many dielectric layers to result to equivalent with three layers. Is confirmed by resource tests and measurements of the partial dischardges a metodic of a choice of working intensity of an electrical field and way of construction of many dielectric layers of isolation. The theory " of intense volume " by definition of the characteristic size of this volume is specified. The practical recommendations for designing seсtions with the combined insulation (polipropilen film and capacitor paper impregnated with transformer oil) are given. Are determined functions of strengthening of an electrical field in zones of the greatest heterogeneity of dielectric at raring edge of electrods. Are developed and the capacitors of a variable voltage КМР-100-0,016 and КМР-10-0,012 are made. The substantiation of a choice of working intensity of an electrical field of pulse capacitors with the increased frequency of following of pulses КИМ-152, КИМ-137, КИМ-141 is specified which provides the given resource with given reliability and in which are used the combined insulation or rounding edge of electrode. Is shown, that the increase of specific energy of capacitors up to 20 % is achieved.
