5 Design and construction 신규 추가 신규 추가	5 Design and construction 5.19 X-ray emission Subclause 5.19 of IEC 62271-1:2007 is applicable. When subjected to high test voltages with the contacts open, vacuum interrupters may emit X-rays. In order to ensure that these are of an acceptable level all vacuum interrupters shall comply with 6.11. Subclause 6.11 sets limits for X-ray emission and prescribes the test procedures to be carried out to verify this. NOTE These requirements and test procedures are based on ANSI C37.85-2002 [3]. 5.20 Corrosion Subclause 5.20 of IEC 62271-1:2007 is applicable. Caution has to be taken against corrosion of the equipment during the service life. Corrosion shall not affect the functionality of the equipment under defined service conditions. All bolted or screwed parts of the main circuit and of the enclosure should remain easy to disassemble, as applicable. In particular, galvanic corrosion of materials in contact shall be considered because, for example, it may lead to the loss of tightness or increased contact resistance, reference is made to Annex H. NOTE Corrosion stresses are strongly dependant on the installation. The atmospheric conditions are important, but the installation should consider the solar and temperature variation, the air flow, etc.	구조에 대한 요구사항이 추가
6 Type tests 6.1 General 6.1.1 Grouping of the tests Subclause 6.1.1 of IEC 60694 is applicable. 6.5 Temperature-rise tests Subclause 6.5 of IEC 60694 is applicable with the following additions: The temperature-rise tests of the combination shall be carried out at the rated normal currents of the combination with all fuses of the reference list. However, the number of tests may be reduced by applying the following statement. Compliance with temperature-rise tests of the combination made of the combination base and a given fuse type (referred to as X) demonstrates the compliance of any combination made of the same combination base fitted with another fuse type, at the associated rated normal current of this new combination, provided that the four criteria below are fulfilled: – the fuses have the same length as the fuse X; – the fuses have a rated current lower than, or equal to, those of the X fuses; – the fuses have a rated dissipated power (according to IEC 60282-1) lower than, or equal to, those of the X fuses; – the derating of the fuses within the combination (Ir combination/Ir fuse) is lower than, or equal to, those of the X fuses. As compliance with the above criteria already includes safety margins, the diameter of the fuses need not be considered. 신규 추가 신규 추가 6.101 Making and breaking tests 6.101.1 Conditions for performing the tests In principle, the tests detailed in 6.101 (making and breaking tests) verify only the performance of the particular combination of switch and fuses actually tested. However, it is recognized that it may well be impractical to a) test a given switch-fuse combination base with every type of fuse; b) repeat combination tests whenever alterations are made in the design of the originally tested fuses. Therefore, compliance with this standard may also be deemed to apply for alternative, untested or partially tested combinations made of combination base and fuses, provided that the following conditions are met: 1) any fuse considered shall comply with its standard (IEC 60282-1); 2) the same type of striker shall be fitted, i.e. medium or heavy in accordance with IEC 60282-1; 3) the requirements for the alternative type of fuse stated in 6.101.2.1, 6.101.2.2 and 6.101.2.3 shall be met; 4) for fuse-switches only, any change in fuse-link mass shall not invalidate breaking characteristics due to change in the mechanical operation (i.e. opening speed). 6.101.3 Behaviour of the combination during tests For combinations with vacuum switches, a maximum of three non-sustained disruptive discharges (NSDD) are allowed during the entire test programme. An NSDD is defined as a disruptive discharge between the contacts of the switch during the power-frequency recovery voltage period, resulting only in a high-frequency current flow. A resumption of power-frequency current is not allowed. 신규 추가	6 Type tests 6.1 General 6.1.1 Grouping of the tests Subclause 6.1.1 of IEC 62271-1:2007 is applicable with the following additions: – Short-circuit making and breaking tests may be performed on an additional specimen; – Additional test samples may be used for additional type tests. 6.5 Temperature-rise tests Subclause 6.5 of IEC 62271-1:2007 is applicable with the following additions: The temperature-rise tests of the combination shall be carried out at the rated normal currents of the combination with all fuses of the reference list. However, the number of tests may be reduced by applying the criteria of 6.105.2. 6.10 Additional tests on auxiliary and control circuits Subclause 6.10 of IEC 62271-103:2011 is applicable. 6.11 X-radiation test procedure for vacuum interrupters Subclause 6.11 of IEC 62271-1:2007 is applicable with the following addition. As this test is independent of the switching device, but only applied to the interrupters (vacuum bottles) alone as a component, the test results can be valid for several types of switching devices provided the type of interrupter is properly identified and the tested open gap spacing is lower than used in the switch-fuse combination. 6.101 Making and breaking tests 6.101.1 Conditions for performing the tests 삭제 6.101.4 Behaviour of the combination during tests For combinations with vacuum switches, non-sustained disruptive discharges may occur during the recovery voltage period following a breaking operation. However, their occurrence is not a sign of distress of the switching device under test and they do not pose any risk to a system in service. Therefore, their number is of no significance in the interpretation of the performance of the device under test. Where NSDDs are seen during normal testing they shall be reported in order to explain the irregularities in the recovery voltage. 6.105 Extension of validity of type tests 6.105.1 Dielectric The dielectric properties may be affected when using other diameters than that of the tested fuse. Extension of validity is restricted to fuses with same overall dimensions. 6.105.2 Temperature rise Compliance with temperature-rise tests of the combination made of the combination base and a given fuse type (referred to as X) demonstrates the compliance of any combination made of the same combination base fitted with another fuse type, at the associated rated normal current of this new combination, provided that the four criteria below are fulfilled: – the fuses have the same length as the fuse X; – the fuses have a rated current lower than, or equal to, those of the X fuses; – the fuses have a dissipated power (according to IEC 60282-1) lower than, or equal to, those of the X fuses; – the derating of the fuses within the combination (Ir combination/Ir fuse) is lower than, or equal to, those of the X fuses. As compliance with the above criteria already includes safety margins, the diameter of the fuses need not be considered. 6.105.3 Making and breaking Compliance with this standard is also be achieved by alternative untested or partially tested combinations made of combination base and fuses, provided that the following conditions are met: a) any fuse considered shall comply with its standard (IEC 60282-1); b) the same type of striker shall be fitted, i.e. medium or heavy in accordance with IEC 60282-1; c) the alternative type of fuse is such that the cut-off current and operating I2t of the alternative type, as established by test-duty 1 of IEC 60282-1, are not greater than those of the tested type similarly established; d) for fuse-switches only, any change in fuse-link mass shall not invalidate breaking characteristics due to change in the mechanical operation (i.e. opening speed).	인용표준 대체 추가 시험품을 사용할 수 있다는 내용이 추가 인용표준 대체 시험항목 인정(?)에 대한 내용이 6.105.2항으로 이동 보조 및 제어회로에 대한 시험 추가 VI에 대한 X선 방사량 측정시험 추가 시험항목 인정(?)에 대한 내용이 6.105.3항으로 이동 비지속성파괴방전 (NSDD) 발생횟수에 대한 허용기준 개정 퓨즈 치수가 완전 일치하는 경우에만 절연시험항목 인정(?)
