Product details
overview
YN-800A series microcomputer comprehensive protection and measurement device is a high-performance microcomputer comprehensive protection and measurement device that integrates protection, measurement, metering, control, and communication. This series of protection and measurement devices uses an advanced 32-bit high-performance embedded controller as the main CPU, adopts fully isolated, high-speed and safe fieldbus technology, built-in operation circuit, and large screen Chinese character liquid display. Its functions, performance and technical indicators are at the leading level in China. All models of devices can be installed locally on switchgear with voltage levels of 110KV and below.
FEATURES
The design concept of the basic hierarchical distributed electrical monitoring and management system is that one component (one interval) corresponds to one device, each interval has independent functions, and each device is connected through a networkState flexibility greatly improves the reliability of the entire system, and any device failure does not affect the normal operation of other devices and systems.
●Adopting advanced 32-bit high-performance embedded processors as the main CPU, the protection module is completely separated from other modules (telemetry, remote control, remote signaling) in software design: the protection function does not rely on communicationThe communication function does not affect the normal operation of protection even if the network is paralyzed.
●Due to the use of safe and reliable fieldbus technology, large data can be transmitted through a communication interface, and the information of each device can be shared at the communication layer, saving control cables and simplifying secondary wiring.
●High speed RS485 network, supporting dual networks, with an actual transmission rate of up to 115.2Kbps.
●Built in operation circuit and anti bounce circuit, further simplifying the design and wiring of the switchgear, and improving reliability.
●Adopting a fully enclosed back plug-in structure, with internal strong and weak electrical separation, and carefully designed anti-interference circuits, the device's anti electromagnetic interference and seismic resistance are greatly improved, fully meeting various EMC tests specified in IEC255 and GB/T14598.
●The device adopts a fully localized large screen LCD display, with a user-friendly human-machine interface and easy operation through a small keyboard. The tree shaped menu, remote signaling, telemetry, trip reports, alarm reports, and other internal information of the device can be displayed in Chinese on the LCD, making debugging, operation, and maintenance convenient.
