ZCH32-12 Outdoor Medium Voltage Vacuum Recloser

ZCH32-12 Outdoor Medium Voltage Vacuum Recloser

The ZCH32-12 outdoor medium voltage vacuum recloser is a new type recloser that comprises vacuum circuit breaker and recloser controller. The microcomputer protection function init can achieve quick-breaking, delayed quick-breaking,and over current three stage protection. The recloser has many functions such as flexiblesetting, definite time characteristics, adjustable protection value and delayvalue, back up protection value with auto-switchover, cooling load auto-delay.Up to three times of reclosingwith any reclosingintervals can be set at the same time, while you can activate any of the reclosing settings as you want.

The ZCH32-12 outdoor medium voltage vacuum recloser has manyfunctions including measuring, control, monitoring, communicating, and telecontrol. It features withhigh integration, flexible configuration, and user friendly interface. Bothsimple and complex powerdistribution system can adopt this recloser. Using this fundamental device, basicautomatic functions of the distribution system can be achieved withoutbackground system, or you can apply it to a distribution system with backgroundsystem to achieve great stability and reliability.

The ZCH32-12 outdoor medium voltage vacuum recloser is also suitable for constructing and upgrading the10KV distribution system in cities and rural places, oil fields, mines,industrial company, and automatic railway system.
