GB/T 28565-2012High-voltage alternating-current series capacitor by-pass switches (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses redrafted law revision using IEC 62271-109:2008 "high-voltage switchgear and control equipment Part 109. AC Stream series capacitor bypass switch. " this standard and IEC 62271-109:2008 main differences are as follows.

--- Scope. According to China's circumstances, to apply to the frequency of 50Hz, 66kV and above voltage AC system series capacitance Used bypass switch, remove the relevant contents of the frequency of 60Hz. Consider closing the bypass can be performed at 60Hz test loop and input current type test, it retains the above test next 60Hz relevant content.

--- Rated voltage. According to the Chinese situation, increased 1100kV relevant content.

--- Rated bypass closing current IBP. according to project needs, increased 160kA, peak.

--- Nominal bypass input current IINS. according to project needs, to be equal or greater than the rated current of the capacitor bank.

--- Joint and brake release action voltage range. According to the Chinese situation, to 65% of rated power supply voltage of closing means (DC) or between 85% to 110% (AC).

--- Shunt opening release action voltage range. According to the Chinese situation, to the opening device rated supply voltage of 85% to 110% between.

--- Plurality of release. according to project needs, the requirements of the rated voltage of 72.5kV and above-ground bypass switch provides two and a joint Opening release.

--- Release of the minimum operating supply voltage. According to the Chinese situation, to not less than 30% of the rated supply voltage.

--- Earlier requirements. According to the Chinese situation, an increase of inter-pole-year requirement. If the provisions of the inter-pole operation does not provide for the same period Special requirements, contact the biggest difference when closing moment of contact should not exceed a quarter of the nominal cycle frequency, sub-gate contact the biggest difference separating the moment should not exceed six per week rated frequency wave.

--- Factory mechanical operation test. According to China, the requirements on the full bypass switch, including 50 points - combined cycle operation.

--- Field operation test. According to China, the mechanical operation test required by the factory.

The chapters in this standard, the order of the arrangement with the IEC 62271-109:2008 "high-voltage switchgear and control equipment Part 109. AC Stream series capacitor bypass switch "basically the same.

The standard proposed by China Electrical Equipment Industrial Association.

This standard by the national high-voltage switch equipment Standardization Technical Committee (SAC/TC65) centralized.
