山东变电站微机五防电编码锁
    近年来,随着微机五防技术的应用和发展,微机五防广泛运用于新建或扩建的发电厂及变电所,同时,许多老厂、变电所也在进行微机五防系统的加装或改造。电气防误装置是防止误操作的重要技术措施,本文就电气防误闭锁与现代微机五防系统在防误性能、可靠性及运行操作、检修维护等几个方面做了比较,提出了完善的防误闭锁解决方案。
    变电站微机五防电编码锁,属于一种具有自动安全闭锁装置的电编码锁。包括电编码锁锁体和与之配合的微机五防钥匙,电编码锁锁体内的常开触点串联在变电站开关或电动刀闸的控制回路当中,在微机五防钥匙插入状态该常开触点接通。在上述控制回路当中,串联有辅助触点,由轻触式弹簧片实现连接;轻触式弹簧片的动作是由与按钮3连动的绝缘传动部件控制的。
    本实用新型具有避免恶性误操作事故发生的积极效果。
    In recent years, with the computer error prevention technology application and development of microcomputer five prevention, widely used in new or expansion of the power plant and substation, at the same time, many old plants, substations are under microcomputer five prevention system or the installation of transformation. Electric error preventing device is to prevent the misuse of the important technical measures, the electrical misoperation proof lockout with modern microcomputer five prevention system in preventing error performance, reliability and operation, maintenance and so on several aspects to do quite, put forward to perfect the error lockout prevention solutions.
    Substation five microcomputer electric coding lock, belonging to a safety locking device with automatic electric coding lock. Including electric coding lock body and matched with the microcomputer five prevention keys, electric coding lock body normally open contact Series in substation switch or electric knife gate control circuit, the microcomputer five prevention key is inserted into the state of the normally open contact. In the control circuit, connected in series with the auxiliary contact, a touch type spring connecting; touch type spring action is made with the button3 linkage insulation transmission member control.
   The utility model has the advantages of avoiding misoperation accident occurring positive effect. http://www.lnat.com.cn/.
