Product Description
Product Description1.IntroductionKYN28 (GZS1)-12 indoor AC metal-clad withdrawable switchgear used for packaged power distribution equipment used for rated voltage of 3 ~ 12kV three-phase AC 50Hz single busbar and single busbar sectional system. It is widely used for control, protection and monitoring in different fields, such as for power distribution in large power plants, electricity transmission of small and medium-sized generators, power supply in mining enterprises, power transmission and distribution of secondary substations in electric power system, and starting of large high-voltage motor starter. The switchgear meets the requirements of IEC298, GB3906-1991 and other standards.2.FeaturesGZS1 - New switchgear with advanced technologies in China
- Switchgear circuit breaker is the centrally-installed handtruck type with rated current from 630A to 3150A and short-circuit breaking current up to 50kA. It is the substitute product of traditional 12kV switchgear.
GZS1 - Safe and reliable switching equipment
- Full metal-clad and fully enclosed structure
- Take measures for electric field equalization; with higher insulating performance
- Independent separation between low voltage compartments and between all high voltage compartments
- Quick closing grounding switch is used for grounding and artificial short-circuit
- All operations of the equipment (including opening and closing of the circuit breaker, movement of circuit breaker truck, and opening and closing of the grounding switch) can be performed when the doors are closed.
- Reliable "five-prevention" locking function; provide effective avoidance of misoperation
- Through observation window, you may easily find the circuit breaker ON/OFF status, the position of truck, the mechanism energy storage state, the ON/OFF position of the grounding switch and the connection conditions of the cable head.
GZS1 - Practical switchgear
- Enclosure has good sealing performance with protection degree of IP4X
- Vacuum circuit breaker truck is maintenance-free type
- Interchangeability of truck is excellent
GZS1 - Intelligent switchgear with advanced technical level
- The switchgear equipped with advanced microelectronic and microcomputer technologies becomes more intelligent.
- It can be equipped with a variety of intelligent protection devices, providing comprehensive protection of equipment and lines and functions of "automatic monitoring" and "automatic diagnosis".3.Main Technical Data Item | Unit | Data |
