Product Description

VS1-12 Indoor AC Vacuum Circuit Breaker

1. Product Introduction

VS1-12 Indoor AC Vacuum Circuit Breaker is the electric system switchgear of rated voltage 12kV/24kV.lt is also as the control and protection unit of industrial enterprises and mines, power station and substation device. VS1 Series Indoor AC HV Vacuum Circuit Breaker can be proceeded frequent operation and has many times breaking and rapid reclosure capacity, and has reliable interlock function. The CB is in line with GB/T1984-2014"AC HV CB" ,JB/T3855-2008 “3.6-40.5kV indoor AC HV vacuum CB", DLlT403-2000 “10-40.5kV HV vacuum CB ordering technical condition" and IEC62271-100:2008 . The device is front and back split charging structure, not only as a fixed installation unit but also match handcart unit with base plate cart. Intelligent components can be selected to realize on-line monitoring and fault diagnosis of contact temperature, mechanical characteristics and partial discharge. Remote monitoring and maintenance can be achieved through mobile phones and Internet of Things cloud platform .

4.STORAGE AND TRANSPORTATION

Transportation

VS1-12 Indoor AC Vacuum Circuit Breaker is packaged individually, fixed on the inner frame and made the appropriate protection, when circuit breaker is lifting, lifting hook hanging on the lifting hole that is clearly identified circuit breaker. When carrying, does not force the upper and lower arm, at the same time it should not make a greater shock and vibration to circuit breaker.

Storage

Before operating, the VS1-12 Indoor AC Vacuum Circuit Breaker must be stored in a dry, dust-free and ventilated place. At the same time the VS1-12 Indoor AC Vacuum Circuit Breaker must be in the opening position, and the tension spring mechanism is discharged
