Company Profile

Interlocked Fuse Protection Gas Insulated Switchgear RMU

GB ISO 12KV Gas Insulated Switchgear Medium Voltage Ring Main Unit

Product Introduction

General

The Fuse switch which named F-unit is a double-position load switch with an independent grounding switch, the tripping

device and the load switch farms the load switch-fuse combination.

The Grounding switch uses double mode, which can be grounded on both sides of the fuse at the same time, thus it ensures

that the fused fuse is not charged other the earthing switch is closed. Double grounding switch is interlocked mechanically, and primary ground operates grounding of two earthing switches of the same time.

The front cover of the fuse compartment is also mechanically interlocked with the earthing switch, and only when it is founded,

the fuse can be contacted.
