Introduction This introduction is not part of IEEE Std C37.015TM-2009, IEEE Guide for the Application

5、of Shunt Reactor Switching. The subject of shunt reactor switching is complex. The approach taken in the main text of the guide is to present a basic method for the application of circuit breakers for the purpose, which considers only load side circuit characteristics. The method is conservative and

6、 will be adequate in many instances. However, by reference to a series of notes, the general case (which incorporates the influence of the source side characteristics and the parallel capacitance of the circuit breaker) is presented. The user of this application guide is encouraged to exercise due d

7、iscretion in the choice of the basic or general method for the application under consideration. Consideration should, in addition, be given to the magnetic effects associated with air core shunt reactors. This standard is a revision of IEEE Std C37.015TM-1993. Listed as follows, for information and

8、guidance, are the substantive changes: The terms “medium voltage” (MV), “high voltage” (HV), and “extra high voltage” (EHV) have been replaced by a voltage range. Subclause 5.2.2 (gapped surge arresters) of the 1993 edition has been moved to an annex (Annex H). A list of symbols has been added (Anne

9、x G). Some of the figures have been redrawn. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations.

39、sclaimers.html. 1. Overview 1.1 Scope This application guide applies to ac high-voltage circuit breakers rated for shunt reactor switching. The guide covers the specific cases of switching directly grounded shunt reactors, ungrounded shunt reactors, and shunt reactors grounded through a neutral reac

40、tor. Directly grounded reactors are common on systems having a voltage of 60 kV and above, whereas ungrounded reactors are commonly applied on systems having a voltage below 60 kV. Schemes where the reactor is grounded through a neutral reactor are usually applied only on systems having a voltage of

41、 60 kV and above. Whereas this application guide is directed toward circuit breakers, it is recognized and accepted that other switching devices such as high-voltage load break switches and circuit switchers are capable of shunt reactor switching and this guide may be applied as appropriate. 1.2 Pur

42、pose This guide is intended for general use in the application of ac high-voltage circuit breakers for shunt reactor current switching. The current to be interrupted is generally less than 300 A rms; however, shunt reactor switching imposes a unique and severe duty on the connected system and the ci

43、rcuit breaker. Successful interruption is the result of a complex interaction between the circuit breaker and the circuit; this interaction can result in significant overvoltages. The purpose of the guide is to describe, principally for the benefit of the user, the shunt IEEE Std C37.015-2009 IEEE G

44、uide for the Application of Shunt Reactor Switching 2 Copyright 2010 IEEE. All rights reserved. reactor switching duty, the overvoltages generated, and the control of those overvoltages. The guide further details the specification of circuit breakers and procedures to predict field performance based

45、 on test data. 2. General application conditions 2.1 Maximum voltage for application The continuous operating voltage should not exceed the rated maximum voltage for the circuit breaker. 2.2 Frequency The rated power system frequency (fr) is 50 Hz or 60 Hz. 2.3 Shunt reactor load current The capabil

46、ity of circuit breakers to interrupt inductive currents is generally not a concern. The circuit breaker typically will interrupt the current at the first current zero after contact parting but may not be immediately capable of withstanding the high magnitude recovery voltages that can then appear ac

47、ross the contacts. This can result in a reignition followed by an additional loop of rated frequency current and successful interruption. Refer to 2.5. 2.4 Interrupting time The interrupting time of a circuit breaker is the interval between energization of the trip coil and the interruption of the c

48、urrent in all poles on an opening operation. Refer to 2.3 and 5.8. 2.5 Transient overvoltages An important consideration for application of circuit breakers for shunt reactor current switching is the transient overvoltages generated on interruption of the current and by subsequent reignitions. Refer

49、 to Clause 3. 2.6 Fault interrupting capability Fault interrupting capability may not be required for all shunt reactor switching applications. If fault interrupting capability is not a requirement, the short-time current rating of the circuit breaker should equal the fault level applicable to the shunt reactor location.
