The new switchgear looks to provide stability and reliability for electrical power systems
Energy engineering solutions provider Brush group launches Cryno, a versatile switchgear solution offering easy insulation and maintenance along with enhanced safety for operators. It combines Brush’s previous Eclipse and Quantum switchboards to create this new solution.
Cryno is a 12kV fixed pattern, indoor, metal-enclosed, vacuum switchgear, providing a space-saving footprint in design.
Brush Group CEO Nicolas Pitrat said: “Our switchgear plays a vital role in maintaining the stability and reliability of electrical power systems across a wide range of applications. CRYNO is the next evolution in switchgear technology; engineered to meet the growing demand for compact and reliable solutions for indoor installations with enhanced performance and safety.”
Sleeved busbars constructed from hard-drawn, highly conductive copper are used in the feeder/incomer panel, having a current rating of up to 2000A. The busbar allows expansion at both ends of the switchboard. A fully interlocked, manually operated three-position disconnector allows three different positions: ‘service’, ‘isolated’, and ‘earth on/test access position’. Its status is indicated by the front three-panel mimics.
The vacuum interrupter assembly, magnetic actuator mechanism and drive mechanism are supported by a single moulding. Permanent magnets hold a solenoid plunger in the tripped or closed position, on which a single-coil magnetic actuator mechanism is based on.
The primary circuit has three-phase cast resin voltage transformers along with a manually operated off-load disconnector. Protection schemes can be enabled in a single panel through CT accommodation and still allow for metering provision. The CT designs are rated in keeping with the short time withstand level of equipment.
Arc interruption capabilities are enhanced by the use of vacuum switching technology, minimising downtime and increasing security. Installation and maintenance are improved by the fixed pattern configuration. Durability and protection from indoor environmental factors are granted by its metal-enclosed design, making it suitable for multiple applications.
Energy Networks Association (ENA) has issued a Notice of Conformity Certificate for the Cryno, which is also SF6 free. It has applications from distribution network operators (DNO) and utility companies to commercial ventures.
The new switchgear has been built and designed in Wales, with its name being pronounced ‘Cruh-no’, meaning ‘compact’ in Welsh. The switchgear is manufactured at Brush’s facility in Blackwood in the Welsh Valley.
