13、 61180-1:1995 ii BSI 03-2000 National foreword This British Standard has been prepared under the direction of the Power Electrical Engineering Standards Policy Committee. It is identical with IEC 1180-1:1992 High-voltage test techniques for low-voltage equipment. Part 1: Definitions, test and proced
14、ure requirements, published by the International Electrotechnical Commission (IEC). In 1994 the European Committee for Electrotechnical Standardization (CENELEC) accepted IEC 1180-1:1992 as European Standard EN 61180-1:1994. As a consequence of implementing the European Standard this British Standar
15、d is numbered as BS EN 61180-1 and any reference to BS 7640-1 should be read as a reference to BS EN 61180-1. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British
16、 Standard does not of itself confer immunity from legal obligations.

30、rovide a standard covering the high voltage testing of low-voltage equipment. It is based on IEC 60-1:1989. The standard is in two parts. Part 1 covers general definitions and requirements, where sections 1 to 3 may be applicable to all kinds of electrical equipment, sections 4 to 6 apply to electri
31、cal equipment without voltage limiting devices, section 7 applies to voltage limiting devices alone, and section 8 applies to equipment incorporating non-linear or voltage limiting devices. Part 2 covers measuring systems and test apparatus (in preparation). This standard includes high-voltage and i
32、mpulse current testing as well as a combination of both. This standard will be of special interest to product committees such as TC 2, SC 12B, SC 17B, SC 17D, TC 22, TC 23, SC 37A, TC 61, TC 64, TC 65, SC 66E and TC 74. Section 1. General 1.1 Scope This part of IEC 1180 is applicable to: dielectric
33、tests with direct voltage; dielectric tests with alternating voltage; dielectric tests with impulse voltage; tests with impulse current; tests with combinations of the above. This standard is applicable only to tests on equipment having a rated voltage of not more than 1 kV a.c. or 1,5 kV d.c. This
34、standard is mainly applicable to type testing. It may also be applied or adapted for sample and routine testing as specified by the relevant technical committee. It is not intended to be used for electromagnetic compatibility tests on electric or electronic equipment. This standard provides the rele
35、vant technical committees as far as possible with: defined terms of both general and specific applicability; general requirements regarding test objects and test procedures; methods for generation and measurement of test voltages and currents; test procedures; methods for the evaluation of test resu
36、lts and to indicate criteria for acceptance; requirements concerning approved measuring devices and checking methods. Alternative test procedures may be required and these shall be specified by the relevant technical committees. 1.2 Normative references The following normative documents contain prov
37、isions which, through reference in this text, constitute provisions of this part of IEC 1180. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 1180 are encouraged to investigate the pos
38、sibility of applying the most recent editions of the normative documents indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

40、 Impulse techniques and insulation 2.1.1 impulse an intentionally applied aperiodic transient voltage or current which usually rises rapidly to a peak value and then falls more slowly to zero NOTEThe term “impulse” is distinguished from the term “surge”, which refers to transients occurring in elect
41、rical equipment or networks in service. 2.1.2 partial breakdown this phenomenon may occur when solid insulation is stressed by impulse voltages. It is indicated by a stepwise reduction in impulse voltage waveform which occurs earlier in time in successive impulses, or by other effects specified by t
42、he relevant technical committee. This indicates progressive deterioration of the insulation 2.1.3 clearance IEV 441-17-31 the shortest distance in air between two conductive parts 2.1.4 creepage distance IEV 151-03-37 the shortest distance along the surface of an insulating material between two cond
43、uctive parts 2.1.5 solid insulation solid insulating material interposed between two conductive parts 2.2 Characteristics related to disruptive discharge and test voltages 2.2.1 disruptive discharge the failure of insulation under electrical stress, in which the discharge completely bridges the insu
44、lation under test, reducing the voltage between the electrodes practically to zero. It applies to electrical breakdown in solid, liquid and gaseous dielectrics and combinations of these NOTE 1Non-sustained disruptive discharges in which the test object is momentarily bridged by a spark or arc may oc
45、cur. During these events, the voltage across the test object is momentarily reduced to zero or to a very small value. Depending on the characteristics of the test circuit and the test object, a recovery of dielectric strength may occur and may even permit the test voltage to reach a higher value. Su
46、ch an event should be interpreted as a disruptive discharge unless otherwise specified by the relevant technical committee. NOTE 2Some non-disruptive discharges are termed “partial discharges” and are dealt with in IEC 270. NOTE 3The term “sparkover” is used when a disruptive discharge occurs in a g
47、aseous or liquid medium. The term “flashover” is used when a disruptive discharge occurs over the surface of a dielectric in a gaseous or liquid medium. The term “puncture” is used when a disruptive discharge occurs through a solid dielectric. 2.2.2 Characteristics of the test voltage Those characte
48、ristics specified in this standard in order to define the different types of test voltage. 2.2.2.1 prospective characteristics of a test voltage the characteristics which would have been obtained if no disruptive discharge or operation of a voltage limiting device had occurred. When a prospective ch
49、aracteristic is referred to, this shall always be stated 2.2.2.2 actual characteristics of a test voltage those which occur during the test at the terminals of the test object 2.2.2.3 value of the test voltage the value of the test voltage is defined in 4.1.1, 5.1.1 and 6.1.1.1 Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 05:59:40 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 61180-1:1994 BSI 03-20005 2.2.3 disruptive discharge voltage the value of the test voltage causing disruptive discharge, as specified
