25、S OF OPEN CONSTRUCTION 1 Scope and object This International Standard gives the rules for all power resistors (for example, braking, heating, snubber and filter) used in the power and auxiliary circuits on board rolling stock irrespective of the circuit and the type of vehicle where they are used. T
26、hese resistors are generally of open construction and are used in polluted areas. The construction consists of resistor elements of grids, plates, strips, ribbons or wires. NOTECertain of these rules may, after agreement between user and manufacturer, be used for electrical equipment installed on ot
27、her vehicles such as mine locomotives, trolley buses, etc. This standard states the characteristics of the resistors; the service conditions with which the power resistors have to comply; the tests intended for confirming that these conditions have been met and the methods to be adopted for these te
28、sts; the information to be marked on, or given with, the resistors. This standard does not give requirements relating to general service conditions and general rules which are given in IEC 60077-1. The object of this standard is to adapt the general rules given in IEC 60077-1 to power resistors for
29、rolling stock in order to obtain uniformity of requirements and tests throughout the corresponding range of components and to avoid the need for testing to two different standards. 2 Normative references The following normative documents contain provisions which, through reference in this text, cons
30、titute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edi

37、 more resistor elements installed in an enclosure intended to form part of a forced air cooling duct. NOTE 2Resistor frame is used for resistors having one or more resistor elements installed on a common frame for natural cooling in open air. 3.2.2 resistor section resistive circuit contained betwee

40、ex A). NOTE 2Double insulation in this context does not refer to double insulation used for protection against electric shock (see IEC 60364-4-41). 3.4 multi-stage insulation insulation system having more than one stage of insulation and an intermediate frame between consecutive stages NOTE 1 An ins
41、ulation system having no more than one stage is termed “single insulation“. NOTE 2For an insulation system having more than one stage, those stages other than the primary insulation are commonly known as “secondary insulation”. 3.5 primary insulation first stage of a multi-stage insulation between l
