Advanced Protection & Control Solutions for High-Voltage Electrical Equipment
Integrates line protection, transformer protection, motor protection, and capacitor protection functions to provide comprehensive protection, monitoring, and control capabilities for high-voltage electrical equipment.
High-quality aluminum chassis with brushed oxidation surface treatment. The chassis features elegant appearance and excellent shielding effect. Rear side uses pluggable terminal blocks with fixed flanges for convenient on-site debugging, maintenance, and replacement.
9 analog input channels including three-phase voltage, three-phase protection current, zero-sequence voltage, high-voltage zero-sequence current, and low-voltage zero-sequence current. Three-phase voltage adapts to both three-PT star connection and two-PT VV connection.
11 digital input channels to meet switch input requirements for middle-mounted cabinets and ring network cabinets. 3 channels are programmable inputs that can be configured according to actual on-site wiring, ensuring both convenience and flexibility.
7 relay output contacts with independent remote trip and close outputs for reliable control operations.
High-speed RS485 communication interface with optoelectronic isolation and lightning protection. Communication rate supports up to 38400bps.
Large-screen LCD display with Chinese menu operation for friendly human-machine interface. Settings, input names and statuses, fault information, etc., are all displayed in Chinese for convenient on-site setting adjustment and fault record query.
Complete fault recording and waveform capture functions display fault occurrence time, fault current and voltage data, and fault waveforms directly on the LCD screen.
High-precision clock chip enables accurate recording of various fault information. Also supports receiving network time synchronization from the distribution network master station.
