KYN28-12 model Metalclad Centered Metal-enclosed Switchgear(switchgear for short hereunder) is a new p roduct independently designed and developed by Yufeng after absorbing international adv anced tech nology, which can replace the old model metal-enclosed switchgears, such as KYN1-10, JYN2-10, GFC-10, etc. The product has obvious advantages as follows:
1.1 The enclosure is completely formed by Al-Zn coated steel plate after multiple bending processed by CNC machine, and then is assembled with bolts, which has strong mechanical strength and effectively assu re the neatn ess and good appearance. The door is painted by plastic powder and has strong anti-impact and corrosion proof ability. The protection grade of enclosure is IP4X.
1.2 The main circuit breaker can be VD4 model VCB (ABB), C3 series fixed type LBS or VS1, ZN73 model VCB produced by yufeng, or some homemade VCBs (e.g. VK, ZN21).
1.3 For circuit breaker, the air insulation distance shall be over 125mm, and the composite insulation shall be over 60mm. All VCBs has unique advantages of long life, high reliability, less maintenance and small size.
The switchgear applies to three phase power system of rated voltage 3.612kV AC 50Hz for receiving and distributing power energy, and also for circuit control, monitor and protection. It can be used in single-busbar system, single-busbar sector system or double-busbar system. The switchgear accords with standards of IEC 298, IEC 694, GB3906 and DIN.VDE 0670 and so on. Furthermore, it has perfect and reliable anti-misoperation function.
