9100 series IEDs Introduction ● This series of protective device is suitable for a variety of 10kV and below the voltage level of three load supply and distribution system, as a protective device in the system transformers, circuit, a capacitor. ● This device is used during the development and design of the same software platform, so for all the different types of objects to be protected can be protected. ● Product development and design based on the same platform to improve the high interchangeability and ensure the maintenance of the convenience of a single device, greatly improving the product price. ● The device uses a high-performance 16-bit microcontroller as the main long-term security protection at -10 ℃ ~ + 50 ℃ in the environment, with the time information and protection action event recording, and retentive. Means set protection, measurement, remote signaling and integration, communication using RS-485 bus, the network economy, convenience, can be directly related to the monitoring or protection supervisor network communications, fully functional operating circuit breaker, AC and DC operation compatible for in all kinds of circuit breaker control. It means a 4U height standard structure, Beicha board, in the process of manufacturing quality fully guaranteed. Main features ● three-stage overcurrent protection (optional directional) ● residual overcurrent protection ● Overvoltage protection ● Low voltage protection ● ● PT break automatically detects remote, remote control, telemetry, remote signaling ● 5 open into the collection , remote displacement, accident telesignalling ● 2-way center signal contact ● AC and DC operation - down circuit ● non-volatile memory operation and signal recording ● non-power protection (for gas, oil and other protection)
