GB/T 11022-2011
GB/T 11022-2011 Common specifications for high-voltage switchgear and controlgear standards
Abstract
This standard applies to indoor and outdoor AC switchgear and control equipment operating in power systems with a voltage of 3 kV or higher and a frequency of 50 Hz or lower.
Unless otherwise specified in the product standards related to specific types of switchgear and control equipment, this standard applies to all high-voltage switchgear and control equipment.
〖HT5"H〗Note:〖HTSS〗 〖ZK(〗For the convenience of using this standard, the voltage range of high-voltage switchgear in the general sense refers to a rated voltage of 3.6 kV or higher. In practical applications, the rated voltage range of medium-voltage switchgear is usually 3.6 kV to 63 kV; the rated voltage range of high-voltage switchgear is 72.5 kV to 252 kV; the rated voltage range of extra-high-voltage switchgear is 363 kV to 800 kV; and the rated voltage range of ultra-high-voltage switchgear is 1,100 kV and higher.
