摘要
对微机变压器保护进行了评述,以在电力系统应用并得到推广的CSC-326数字式变压器保护装置的特点及功能为例,探讨了提高变压器保护可靠性的措施,从变压器保护原理角度分析了影响变压器保护可靠性的因素。现场运行证明,该措施有效,满足变压器保护的可靠性、选择性、速动性、灵活性要求。
This article introduces the microprocessor-based transformer protection. Through the description of the characters and functions of CSC-326 digital type transformer protection device which has been widely used in power system as an example, it not only probes into the measures to improve the protection reliability of the transformer but also analyzes the theory of transformer protection for the factor affecting its protection reliability. The operation on site proves that the adopted measures meet four following requirements： reliability, selectivity, speeding, flexibility of transformer protection.
