标准摘要
[中文适用范围]: IEC 60519 的这一部分适用于在电压带 1 和 2 下工作的用于加热和熔化玻璃的间接电阻加热设备。这些特殊要求也适用于通过电极引入的电流直接电阻加热和熔化玻璃的设备穿过待加热的炉料。本标准的目的是确定用于加热和熔化玻璃的间接和直接电阻加热设备的安全要求。注:在提取点提取液态玻璃或类似材料是生产过程的一部分,并不构成电热设备操作的一部分。该标准涵盖了电加热与其他加热方式(例如液体燃料加热)相结合的情况下电气部件的安全问题。这些要求不适用于直接电阻加热设备,由于所使用的技术,IEC 60519-3、IEC 60519-4 和 IEC 60519-8 适用。 [外文原描述]: IEC 60519-21:2008 is applicable to indirect resistance heating equipment for the heating and melting of glass, operating in voltage bands 1 and 2. These particular requirements also apply to equipment for direct resistance heating and melting of glass by means of current introduced by electrodes passing through the charge to be heated. This new edition of IEC 60519-21 takes into account the latest editions of IEC 60519-1, of IEC 60519-2 and of IEC 60050-841.
