Description

The 12kV outdoor pole-mounted SF6 circuit breaker 12kV 630A Recloser SF6 CB


The 12kV outdoor pole-mounted SF6 circuit breaker is a new generation product
developed by our company to meet the new requirements of the primary and
secondary integration of the national grid.The switch configuration fully meets
the requirements of the primary and secondary integration of the national grid.
Mass production.The switch has a compact structure,a reasonable layout,
and complete functions.All indicators meet the requirements of the primary
and secondary fusion of the State Grid.It adopts unified parameter protection CT,
zero sequence CT and zero sequence voltage sensors.It has a wide measurement
range,high measurement accuracy,and reliability High characteristics,complete
analog quantity is convenient for accurate determination of various faults on the line.



Operating environmental conditions
◆ Ambient air temperature:-40℃~+40℃;
◆ Altitude:no more than 3000m;
◆ The surrounding air can be contaminated by dust,smoke,corrosive gas,steam or salt mist.Pollution level:Grade IV;
◆ The wind speed does not exceed 34m/s(equivalent to 700Pa on the surface of the cylinder)
◆ Vibration or ground motion from outside of switchgear and control equipment can be ignored;
◆ The amplitude of electromagnetic interference induced in the secondary system does not exceed 1.10kV.
