Overview
TA-D3000 Series Box Transformer Substation Intelligent Measuring and Monitoring Protection Device is widely used in 35KV and below box-type substation of different voltage classes, wind power plant, solar power station and other equipment’s complete measuring and monitoring protection device. It combines protection, measurement, communications functions, so as to achieve the high/middle/low transformer or line of measuring and monitoring protection function.
Feature
1. 4U standard aluminium classis, combination of plug-in structure, back swap classis, independent function module design, strong and weak electricity separated completely, strong anti-interference capacity, convenient on-site maintenance;
2. It is multi-CPU intelligent plug-in design, switch plug-in realize the real-time entirely self-test; it can detect each relay coil;
3. Contact between plug-ins based on CANBUS bus, reducing the connection between plug-in, realizing plug-in trouble real-time detection;
4. Dual 32-bit system, system redundancy ; protection produced using the Texas Instruments 32-bit floating point DSP processor, the program and data run on the chip; quickly and high reliability;
5. HMI, network communications and other management functions achieved by Philips 32 ARM MCU run fast, with large on-chip memory capacity and strong network interface capabilities;
6. 16 AD sampling, high accuracy; 48 points per cycle sampling, strong harmonic processing capability;
7. Protection modules use computer auxiliary graph interface design principles to facilitate the secondary development of products and functional modifications. Engineering design is flexible and fast;
8. Complete circuit breaker operating circuit with remote tripping and closing, pressure lockout, spring un-stored energy latching switch functions;
9. Flexibility to choose monochrome or large color LCD, Chinese interface menu; flexibility to choose dual Ethernet, dual CANBUS, dual 485;
10. It can save at least 500 incident reports and run reports recently;
11. Human management module use real-time multitasking operating system, tasks such as interface and network have good real-time performance;
12. Able to store 10 sets of protection settings, dual setting area combination of self-test and mutual inspection, safe and convenient setting switch;
13. Standard communication protocol based power industry DL / T667-1999 (IEC 60870-5-103) to facilitate network communication with the computer monitor or the protection manager.
