Intelligent Transmission and Distribution Automation System
I. Overview
This product is the monitoring unit of the overhead line power grid. It cooperates with the On-post switch to realize automatic monitoring, fault analysis and judgment record of line status. It has the functions of driving switch to protect the safety of line equipment, cut off line fault and automatically restore line operation. Suitable for Outdoor Switchgear up to 35kV including vacuum circuit breaker, oil circuit breaker and gas circuit breaker.
This product is an integrated automatic outdoor measurement and control device which integrates line protection, control, voltage and current signal measurement and monitoring. It has all the functions of processing all voltage and current signals of a single overhead line and remote operation of switches.
Supporting communication modes: wireless mode (GSM/GPRS/CDMA), ethernet, WIFI, optical fiber, power carrier, RS232/485,
RJ45 and so on, and can access other station equipment (such as TTU, FTU, DTU, etc.).
Ⅲ. Functional characteristics of distribution automation system
1. Unique battery voltage real-time monitoring technology, battery low-voltage alarm protection, and can configure a variety of options of solar panel power supply and 220 V indoor power supply, greatly ensuring the stability of the controller.
2. Using modular design, control, communication and telecontrol functions to expand flexibly, suitable for feeder automation, with the "three remote" function.
3. Acquisition of three-phase protection current, zero-sequence current, three-phase voltage, zero-sequence voltage, three-phase measurement current, etc.
4. Three-stage current protection, zero-sequence/negative-sequence protection, voltage protection, reclosure (post-acceleration), inrush current protection, harmonic protection, etc.
5. The three characteristic quantities of zero-sequence current, voltage and power direction can be calculated synthetically to realize reliable detection within and outside the fault boundary.
6. RS485, Ethernet interface, GPRS module, short message and handheld remote control with control distance of 50 meters are assembled.
7. It can run in high temperature and cold environment for a long time, and all parts can run stably under extremely harsh conditions.
8. Ultra-high temperature liquid crystal display technology can work in the harsh environment of - 40 ~80 ~C for a long time. All parameters are displayed on the LCD screen. The effect is intuitive and the operation is convenient.
9. Record and save the important information on the line and the user's operation information, up to 100 SOE events.
10. With prepaid arrears tripping function, it is convenient to manage users'electricity consumption.
Ⅳ. Installation indication and outline dimensions of products
1. When installing this product, please fix the controller on the pole with the mounting frame as shown in the figure below. The users of the mounting frame design it by themselves.
2. Fixed the operation panel vertically downward, not inverted.
3. When installing this product, the grounding wire must be connected reliably.
