变电站微机"五防"技术的应用

随着电子技术的发展和计算机在电力系统领域的广泛应用,电力五防也由最初的机械型、电气型,发展到现在的微机"五防"。微机防误闭锁装置经过10多年的发展,其技术水平、制造工艺已进入成熟稳定时期,与传统的防误闭锁装置相比,具有功能完善、闭锁方式简单方便、扩充性强、维护容易、投资省等诸多优点,广泛应用于各种规模尤其是大中型接线复杂的发电厂、变电站中,有效地防止电气误操作的发生,为电力系统的安全生产做出卓越的贡献。微机"五防"以其智能性,操作灵活方便,能达到防止五种误操作事故发生的目的。

Application of Computer "Five Fault Prevention" in Transformer Substation

With the electronic technological development and the extensive application of the computer in the fi eld of the power system, the 5 electricity fault prevention has been developed from the mechanic and electric prevention into the present computer-based fault prevention. The computer fault prevention closedown device in the past more than 10 years development has been mature and reliable in its technology and manufacturing craftwork. Comparing to the traditional fault prevention closedown device, it is provided with the consummate functions, convenient closedown manner, strong expansion, easy maintenance and cost-effective investment and other advantages, and its application in all types of medium and large-sized power plant and transformer substation with the complex connection can effectively prevent the electric fault operation and make the eximious contribution to the security production for the power system.
