工业电热设备直接电弧炉试验方法

[中文适用范围]： 范围和目的本标准规定了交流电（EAFac）或直流电（EAFdc）容量以上的电弧炉（EAF）的主要参数和主要运行特性的试验程序、条件和方法。确定 500 公斤/热量。 EAF 技术还适用于液态金属保持高温或过热至铸造温度的熔炉@（例如，在交流电操作的钢包炉（LF）@中）。 IEC 60146-1-1 涵盖了一些特殊设备@（例如EAFdc@的受控整流器）的测试方法。 IEC 60683 涵盖了矿热炉 (SAF) 的测试方法。 [外文原描述]： IEC 60676:2011 specifies test procedures, conditions and methods according to which the main parameters and the main operational characteristics of electric arc furnaces (EAF) operated either with alternating current (EAFac) or with direct current (EAFdc) with a capacity above 500 kg/heat are established. This third edition cancels and replaces the previous edition published in 2002 and constitutes a technical revision. Significant technical changes with respect to the previous edition are as follows: - Clause 1 (Scope and object) - types of furnaces are more clearly defined. - Clause 2 (Normative references) and Clause 3 (Terms and definitions) have been updated and completed. - New Clause 4 (Features of the EAFsystem) has been added; it mainly concentrates on the tests necessary for high-voltage / high-current electrical equipment in the installation. - Clause 5 (Type of tests and general conditions of their performance) and Clause 6 (Technical tests) have been modified according to today's requirements for safe operation of an EAF.
