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. 1.2 Normative references The following documents for the application of this document is essential.
