两工位负荷开关 12kV 2-Position Loadbreak Switches

12(15)kV Two-Position Sidewall (Horizontal)  mounted Loadbreak Switches Installation Instructions

Introduction

The compact Cooper Power Systems two-position mounted loadbreak/loadmake switch is designed for use in transformer oil, Envirotemp™ FR3™ fluid, or an approved equivalent fluid-filled “Class 1” pad-mounted transformers, submersible distribution transformers, or distribution switchgear.

The two-position switch is hook stick operable and requires minimal input torque to operate. The switch mechanism uses a manually charged, over-toggle, stored energy spring assembly, which is independent of operator speed. The mechanism ensures quick loadbreak or loadmake operation in less than one cycle. Also incorporated into the switch mechanism are internal stops which restrict the handle orientation to only two positions, approximately 90° apart.
