Microcomputer protection and control device XNDQ-600A is an economical protection device which integrates the functions of measurement, control, protection and communication. It is mainly composed of high integration bus-no chip single chip, high precision current and voltage transformer, high insulation strength outlet intermediate relay, high reliability switching power module and other components. The device is widely used in 110KV and below voltage level of power plants, substations, distribution stations, etc., can also be used for some 70V-220V voltage level between the system voltage and current protection and measurement and control . Functions, including but not limited to:
XNDQ-600A microcomputer protection measurement and control device has a variety of protection
Incoming line protection, outgoing line protection, section protection, transformer protection, motor protection, capacitor protection, main transformer backup protection, generator backup protection, PT monitoring protection
Current rate break protection, negative sequence overcurrent protection, negative sequence overcurrent protection, ground protection, overheat protection, locked-rotor protection, positive sequence overcurrent protection, overload protection, undervoltage protection, etc.
High voltage side current break protection, high voltage side limit speed break protection, high voltage side overcurrent protection, high voltage side overload protection, high voltage side negative sequence overcurrent protection, high voltage side negative sequence overcurrent protection, high voltage side ground protection, low voltage side zero sequence overcurrent protection, non-power protection
In addition, the device also supports the custom protection function, and the corresponding protection can be formulated according to the needs of actual operation, so as to realize the user's "tailor-made". Various protection functions are relatively independent, and protection setting, realization, locking conditions and protection casting can be adjusted and formulated independently. The realization of the protection function does not depend on the communication network, and meets the reliability requirements of power system protection The advantages of microcomputer protection measurement and control device XNDQ-600A include:
1, can meet the inventory of more than 20 kinds of protection, to meet the user of different electrical equipment or line protection requirements.
2. According to the needs of actual operation, the corresponding protection is formulated to truly realize the user's "tailor-made".
3. User-defined protection function can realize the special protection not provided in the standard protection library, and meet the user's requirements to the maximum extent.
4, various protection functions are relatively independent, protection setting, implementation, locking conditions and protection casting can be independently adjusted and formulated.
5, the protection function does not depend on the communication network, to meet the reliability of power system protection
