电源变压器在本质安全电路中的研究及设计

Study and Design on the Power Transformer for Intrinsically Safe Circuits

本质安全电路中常用隔离元件为电源变压器、隔离电容、电隔离元件等,本文介绍了电源变压器在本质安全电路中作为隔离器件的重要性,论述了电源变压器在本质安全电路中应用的设计方法、技术要求及相关检验要求,讲解了到达本质安全要求的变压器结构要求及保护措施。

Common isolated components in intrinsically safe circuits are power transformers,isolation capacity and elec- trictiy isolated components and so on. The imporatane of the power transformer as islated elements for the intrinsically safe circuits is presented in the paper, and expound the design method of the power transformer in the intrinsically safe eircuits, technical requirements and related test requirements and explain the stractural requiremtents and protective meas- ures of the trunsforwer up to the intrinsically safe circuit requirements.
