30、ical components - General rules, - Part 3: Electrotechnical components - Rules for d.c. circuit-breakers, - Part 4: Electrotechnical components - Rules for a.c. circuit-breakers, - Part 5: Electrotechnical components - Rules for HV fuses. This document has used IEC 60077-2 as its base and its form a
31、nd structure have been modified to take account of already existing European Standards covering related subjects. 1 Scope In addition to the rules given in EN 60077-1, this European standard provides general rules for all electrotechnical components installed in power circuits, auxiliary circuits an
32、d control circuits, etc., on rolling stock. NOTE Certain of these rules may, after agreement between user and manufacturer, be used for electrotechnical components installed on vehicles other than rail rolling stock such as mine locomotives, trolleybuses, etc. The purpose of this standard is to adap
33、t the general rules given in EN 60077-1 to all electrotechnical components for rolling stock, in order to obtain uniformity of requirements and tests for the corresponding range of components. Electrotechnical components are mainly switchgear and controlgear, irrespective of their control, including
34、 also relays, valves, resistors, fuses, etc. NOTE The incorporation of electronic components or electronic sub-assemblies into electrotechnical components is now common practice. Although this standard is not applicable to electronic equipment, the presence of electronic components does not provide
35、a reason to exclude such electrotechnical components from the scope. Electronic sub-assemblies should comply with the relevant standard. This standard states a) the characteristics of the components, b) the constructional and performance requirements with which components have to comply, c) the test
36、s intended to confirm compliance of the components with these characteristics under these service conditions, and the methods to be adopted for these tests, d) the information to be marked on, or given with the apparatus. This standard does not cover industrial electrotechnical components which comp
37、ly with their own product standard. In order to ensure satisfactory operation of these components for rolling stock, this standard should be used to specify only the particular requirements for railway application. In that case, a specific document should state the additional requirements with which
38、 the industrial components are to comply, e.g. - to be adapted (for example for control voltage, environmental conditions, etc.), or - to be installed and used such that they do not have to endure specific railway conditions, or - to be additionally tested to prove that these components can withstan
39、d satisfactorily the railway conditions.
