The Zha5-40.5 serties high-voitage vaouum circuilt bneaker (hereinafter nefemed to as thecrout breaker) is suftabte for three-phase AC 50Htz, rated votage 40.5V powersyatems, and can be used by mining enterprises, power generation piants, andsubutatons as a source of toad current, cvertoad current and teut curent. The croutbreaker and aperalting mechaniam are ananged vertically, effectively reduaing the depth
of the croult breaser
The thee-phase arc extinquisning chamber and the connected charged body aresolated by tee indepandent apoay resin insutation cyinders, toming a compoetenoulation structure. The ciroult breaker meets the requirements of air dietance and areepsstance under nomal oparalting oonditions, and affectvely reduces the volume of thesroult breaker. The main circut vacuum aro extinguishing chamber and the dynamiostatc conductive connection are inatailed inatde the naulalton cyinder, so that the mainsroult electical oonnections are all thxed connections wfth a phase apacing of onlyS0Oesms ", wtioh has Ngh retaolity.
