The purpose of this product standard is to give additional or amended requirements on AC circuit-breakers as a supplement to those given by IEC 60077-2. During preparation
24、of this product standard, IEC 60056 and IEC 60694 have been considered and their requirements have been kept as far as it has been possible. This product standard makes reference to the general rules for electrotechnical components given in IEC 60077-2, but for general conditions reference is made d
25、irectly to IEC 60077-1. Page4 EN600774:2003 RAILWAY APPLICATIONS ELECTRIC EQUIPMENT FOR ROLLING STOCK Part 4: Electrotechnical components Rules for AC circuit-breakers 1 Scope In addition to the general requirements of IEC 60077-2, this part of IEC 60077 gives rules for AC circuit-breakers, the main
26、 contacts of which are to be connected to AC overhead contact lines; the nominal voltage of these circuits being in accordance with IEC 60850. This standard, together with IEC 60077-2, states specifically: a) the characteristics of the circuit-breakers; b) the service conditions with which circuit-b
27、reakers have to comply with reference to: operation and behaviour in normal service, operation and behaviour in short-circuit, dielectric properties; c) the tests for confirming the compliance of the components with the characteristics under the service conditions and the methods to be adopted for t
28、hese tests; d) the information to be marked on, or given with the circuit-breaker. NOTE 1 Circuit-breakers which are dealt with in this standard may be provided with devices for automatic opening under pre-determined conditions other than those of over-current, for example, undervoltage and reversal
29、 of power current. This standard does not deal with the verification of operation under such predetermined conditions. NOTE 2 The incorporation of electronic components or electronic sub-assemblies into electrotechnical compo- nents is now common practice. Although this standard is not applicable to
30、 electronic equipment, the presence of electronic components does not provide a reason to exclude such electrotechnical components from the scope. Electronic sub-assemblies included in the circuit-breakers should comply with the relevant standard for electronics (IEC 60571). NOTE 3 Certain of these
31、rules may, after agreement between user and manufacturer, be used for electrotechnical components installed on vehicles other than rail rolling stock. This standard does not cover industrial circuit-breakers which have to comply with IEC 60056. For these, in order to ensure satisfactory operation, t
32、his standard should be used to specify only the particular requirements for rolling stock. In such cases, a specific document should state the additional requirements with which the industrial circuit-breakers are to comply, for example: either to be adapted (e.g. for control voltage, environmental
33、conditions, etc.); or to be installed and used so that they do not have to endure specific rolling stock conditions; or to be additionally tested to prove that these components can withstand satisfactorily the rolling stock conditions.
