The QCD3000 series distribution station terminal (DTU) is a monitoring terminal product independently developed by our company for the increasingly widespread application of ring network cabinets and small switching stations in urban power grids. It can work with the distribution network automation master station and substation systems to achieve the collection and control of electrical quantities from multiple lines, detect faults, locate fault areas, isolate them, and restore power supply to non-fault areas, thereby improving power supply reliability.
Technical Features:
- Using a high-performance ARM processor as the hardware development platform and RTX embedded real-time operating system as the software development platform. The product is designed to ensure stability, reliability, high performance, high precision, and easy installation.
- The main processor has 2 standard Ethernet RJ45 ports that can connect to a laptop for maintenance through dedicated maintenance software, allowing for remote maintenance of the main processor, such as parameter modification, program upgrades, etc., facilitating on-site maintenance and improving system availability. The device provides 4 serial ports, which can be configured as 485 or 232, with a communication rate of no less than 9600bps, to facilitate communication with the master station or other station-end devices.
-
- Provides remote and local maintenance interfaces, allowing operators to perform maintenance locally or from remote locations such as the main station.
- Utilizes high-speed sampling technology to achieve fault identification of feeders and three remote monitoring functions.
- Supports various communication methods including wireless, fiber optic, Ethernet, RS232/485, etc.
- Can connect to other station-end devices and forward data.
- Has self-diagnosis and self-recovery functions.
- Features intelligent maintenance for batteries.
- Rich communication protocols, supporting all currently popular protocols (such as IEC60870-5-101, IEC60870-5-104, MODBUS, etc.).
- Electromagnetic compatibility meets IEC61000-4, GB/T13729, DL/T630, DL/T721 standards, suitable for strong electromagnetic environments.
- Adaptable to harsh environments, operating temperature -40℃ to +85℃, resistant to magnetism, shock, and moisture.
