工业电热设备埋弧炉试验方法

[中文适用范围]： 范围和目的本国际标准规定了额定功率500 kVA以上矿热炉（SAF）的主要参数和主要运行特性的试验程序、条件和方法。本标准适用于具有一个或多个电极的SAF。为了确定进一步的技术或经济评估，可能需要进行额外的测试。 IEC 60146-1-1 涵盖了半导体变流器控制炉@（例如受控整流器或受控交流变流器@）的一些特殊设备的测试。 [外文原描述]： IEC 60683:2011 specifies test procedures, conditions and methods according to which the main parameters and the main operational characteristics of a submerged-arc furnace (SAF) with rated electrical power levels above 500 kVA are established. This standard is applicable to SAF with one or more electrodes. In order to determine further technical or economic assessments, additional tests may be necessary. Tests for some special equipment for semiconductor converter controlled furnaces, such as controlled rectifiers or controlled a.c. converters, are covered by IEC 60146-1-1. This second edition cancels and replaces the previous edition published in 1980 and constitutes a technical revision. Significant technical changes with respect to the previous edition are as follows: - Clause 1 (Scope and object) - the types of furnaces covered by this standard are more clearly defined. - Clause 2 (Normative references) and Clause 3 (Terms and definitions) have been updated and completed. - A new Clause 4 (Features of the SAF sytem) has been added; it mainly concentrates on the tests necessary for high voltage/high current electrical equipment in the installation. - Clause 5 (Tests and general conditions) and Clause 6 (Technical tests) have been modified according to today's requirements for safe operation of a SAF.
