Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard uses redrafted Law Amendment uses IEC /T R62271-302.2010 "high-voltage switchgear and control equipment --- 302
Section. a predetermined operation of a very different AC circuit breaker. "
This compared with standard IEC /T R62271-302, the main differences are as follows.
--- Standard name change. a very different between a predetermined operation of high-voltage AC circuit breaker;
--- Scope. according to the actual situation of China's power grid, removing the rated frequency of 60Hz related content;
--- Opening minimum control voltage in accordance with GB/T 11022-2011 requirements in 5.8.2, Table 4 "70%" to "65%";
--- To increase the time constant τ = 100ms relevant content.

Having different predetermined pole of the operating room
AC high voltage circuit breakers
1 Overview
1.1 Scope
GB 1984-2014 Chapter 1 apply with the following modifications.
This standard specifies a very different having a predetermined inter-operation of high-voltage AC circuit breaker design, construction, technical requirements and testing.
This standard applies to outside GB 1984 range, with very different predetermined operation of high-voltage AC circuit breakers, except that
Range GB 1984 equivalents. This standard should be used in conjunction with the GB 1984.
Predetermined different poles of operation can be directly implemented by mechanical means or by electronic ways, these two methods are standard in the present
Within the scope.
Having very different between a predetermined operation of the circuit breaker in most cases under the implementation phase selection for the opening and closing of this standard to deal with such applications breaker
Requirements. Phase selection on the opening and closing related information see CIGRE Technical Manual 262 [1], 263 [2], 264 [3]. This standard does not contain
Related protection and/or control device requirements, unless these devices are part of the circuit breaker.
This standard recognizes that, to achieve two different basic of operating system is configured to.
--- Breaker predetermined different operating independent of a specific phase selection controller implementation and testing;
--- Breaker of predetermined different phase selection is operated by a dedicated controller (it can be integrated in the circuit breaker) to achieve the necessary sensors and auxiliary
Assist devices form part of the test equipment.
Basic requirements for each configuration is the same, but the interpretation of the test results depends on whether the selected phase controller includes a test drive
Preface. Details in this regard be included in Chapter 6 of this standard.
No significant phase of the standard assumptions affect the circuit breaker mechanical properties of various parameters (such as ambient air temperature, control voltage, etc.)
Mutual influence. This assumption has not been verified to comply with all combinations, but in practice, with opening and closing selected operating experience shows that this hypothesis for large
Most commonly used drive technology is effective. Appendix F provides an example of support for this hypothesis.
