Die 24KV-Schaltersc halter einheit besteht aus drei Polen, dem Betätigung mechanismus und dem Betätigung mechanismus gehäuse. Die Reihenfolge der Pole ist A -B - C oder 1-2-3 (Sequenz von links nach rechts, wenn sie von der unteren End seite der Rück schalters einheit aus betrachtet wird.
Jeder 24kV Vakuum-Leistungs schalter durchGOPOWERIst in einen fest isolierten Pol aus wetterfestem cyclo aliphatischem Epoxidharz eingebettet. Dies ermöglicht ein kleines Design sowie Widerstand gegen Umwelt einflüsse.
Kontaktieren Sie unsZW32 series 24KV circuit recloser are used in distribution systems. 24kv vacuum circuit breakes are used to make and break normal and fault currents. Breakers are fully equipped with sensors and a controller to provide a means of protection and control. For more pole top switches at bulk price.
In case of a line fault, breakers can break and make currents several times, thus avoiding longer network interruptions due to temporary faults. The manufacture, design, and testing of the vacuum recloser is based on current standards IEC 62271-111：2019
