Metal-Enclosed High Voltage Switchgear
Model:KYN 28-12 AC metal-clad indoor withdrawable switchgear
| Product overview | |
| The KYN 28-12 AC metal-clad indoor withdrawable switchgear (3.6-12 kV, 3-phase, AC, 50/60Hz) produced by our company is a power transmission and distribution device for accepting and distributing electric power in the sectionalism single-bus system, which is mainly used for accepting electric power of small and medium-sized generators, power distribution of industrial and mining enterprises, accepting and transmitting electric power for secondary substations, starting of large-sized HV motors and used in power plants, its functions are for control, protection and monitoring.It can be additionally used with domestic VS1 vacuum circuit breaker, it can be used with VD4 from ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc. It is truly a power distribution deviece with good performance. |

| Working Conditions |
| Ambient temperature : -15ºC- + 40ºC and the daily average temperature is below 35ºC Humidity: daily average ≤95% monthly average ≤90% daily vapor pressure ≤2.2kpa monthly vapor pressure ≤1. 8kpa Altitude: ≤1000m It is applicable in the place without obvious dust, smoke, corrosive or flammable gas, vapor, salt mist and so forth pollution. The external vibration or ground shaking outside the switchgear and control equipment is negligible. In the secondary system of induction electromagnetic interference amplitude is less than 1.6kv. |
| Structure and Operating Principle |
| KYN28A-12 switchgear is composed of two parts: cabinet and removable components (commonly known as handcart). Cabinet is separated into several functional compartments by steel plates, such as busbar compartment, Circuit breaker compartment, cable compartment and relay instruments compartment, etc. The removable components of the switchgear are configured vacuum circuit breaker handcart, voltage transformer handcart, lightning arrester handcart, isolation handcart and fuse handcart, etc. |

SF6 load break switch SF6 load break switch used in the modular switchgear has multiple functions for 3 working positions, combined with grounding switch and isolation switch. With 0.045 Map SF6 gas filled in a fully sealed epoxy resin enclosure that make its structure enhanced and good insulation performance. Thanks to its design, it ensures the quality and reliability for its's proper operation in switchgear control. Its's mechanical and electrical interlocking systems between the load break switch and the earthing switch, possibility of a wrong-man oeuvre is prevented by these interlocking systems. |

Vacuum circuit breaker The VS1 (VN) vacuum circuit breakers are designed with solid sealed pole type, side-mounted installed, and high mechanical stability. It can be used to store energy with AC and DC power supply, and also be used by manually. It has the advantages of compact size, strong breaking capacity, high insulation strength, no pollution, no danger of explosion and etc. 1.Spring/ permanent magnetic operating mechanism for option. 2. Vacuum interrupter and operating mechanism are installed in a front and rear way, and connected through whole transmission mechanism 3. Reliable performance and free maintenance under frequently operation |
