Switchgears for distribution
| Product Overview | |
| KYN28A-12 Steel-clad Removable-type Metal-enclosed Switchgear (hereinafter called switchgear for short) is applicable in the power system of three phases 50/60HZ. which is used to receive and distribute power as well as control. protect and moniter the circuit of power plant, substation and industrial and mining enterprises and high-rise buildings. KYN28A-12 switchgear has the function of preventing various wrong operations including preventing loading mobile handcart, preventing grounding switch to circuit the breaker in closed position, preventing to close the charged grounding switch and preventing straying into charged compartment and other functions. Switchgear is equipped with excellent mid-set type of VS1, VD4 series high voltage vacuum circuit breaker and enclosed type vacuum circuit breaker. The secondary loop configuration of the switchgear is advanced and reliable control protection devices: Busbar with heat insulation materials or the insulation of the epoxy coating methods, optimizes the electrode shape and compacts the structure. The switchgear is safe and reliable power distribution equipment with advanced technology. stable performance, reasonable structure and easy usage. |

| Service condition |
| 1. Air temperature: Maximum temperature: +40ºC; Minimum temperature:-15ºC 2. Humidity: Monthly average humidity 95%; Daily average humidity 90% . 3.Altitude above sea level: Maximum installation altitude: 1000M. 4.Ambient air not apparently polluted by corrosive and flammable gas, vapor etc. 5.No frequent violent shake |
| Main characteristics |
| 1. Adopt an intelligent switch cabinet operating system (1) The circuit breaker of the switch cabinet enters, exits, opens and closes to realize remote control or local electric operation. (2) The grounding switch of the switch cabinet is opened and closed to realize remote control or local electric operation. (3) All primary contact parts in the switch cabinet adopt visual interface and temperature measurement methodsto ensure the safe connection of all contacts. 2.Adopt intelligent information processing system to diagnose and monitor the failure precursor of the switchgear body (1) On-line detection and over-limit monitoring of busbar and cabinet temperature. (2) On-line monitoring of operating characteristics of circuit breaker opening and closing speed. (3) Online monitoring of the mechanical performance of the operating mechanism. (4) Online detection and alarm of insulation level. 3. Intelligent anti-misoperation operating system (1) Prompts and previews of various operations. (2) Check the operation and lockout of misoperation. (3) Prohibit operation prompts and operating condition prompts. 4. Intelligent function of secondary circuit Intelligent measurement, signal, protection, control and movement. 5. Remembrance of grid failure Wave recording, login, simulation replay and fault recording, provide analysis data. |

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. |
