The microcomputer protection and measurement and control device adopts internationally advanced DSP, surface mount technology and flexible field bus (CAN) technology, which meets the requirements of different voltage levels of substations and realizes the coordination, digitalization and intelligence of substations. This series of products can complete the functions of substation protection, measurement, control, regulation, signal, fault recording, power acquisition, low current grounding line selection, low cycle load shedding and so on, making the technical requirements, functions and internal wiring of the products more standardized. The product adopts distributed protection measurement and control devices, which can be assembled in a centralized way or installed in a decentralized way, and the configuration can be changed at will according to the needs of users to meet the requirements of different schemes. The microcomputer protection device is suitable for the protection, monitoring and measurement of voltage levels below 110KV, and can be used for PT detection of lines, transformers, capacitors, motors, buses, automatic switching circuits of standby power supplies and protection, control and monitoring of main equipment. The unitized design makes it not only convenient to be equipped with primary equipment, but also centralized screen assembly and control. The standardized field bus interface supports the coordinated work of multiple nodes, realizing the common application scope of system-level management and comprehensive information. With the progress of scientific and technological means and higher requirements for applicable environment, the functionality of microcomputer protection is becoming more and more perfect. The general microcomputer comprehensive protection device can be used as the protection and measurement and control of all kinds of electrical equipment and lines in ungrounded systems, small resistance grounding systems, arc suppression coil grounding systems and direct grounding systems with voltages of 35KV and below, and also as the protection and measurement and control of voltage and current in some systems with voltages of 66KV and 110KV.
