Brief Introduction
The microcomputer protection measurement and control device is composed of high-integration, bus-out-of-chip microcontroller, high-precision current and voltage transformers, high insulation strength output intermediate relays, high-reliability switching power supply modules, and other components. It is an economical protection that integrates measurement, control, protection, and communication.
Advantages of Microcomputer Protection Measurement and Control Device
1. It can meet the inventory configuration of more than twenty types of protection, satisfying users' requirements for protection of different electrical equipment or lines.
2. It can be configured with corresponding protection according to actual operation needs, truly realizing users' "tailor-made" needs.
3. Custom protection functions can realize special protections not provided in the standard protection library, maximizing satisfaction of user requirements.
4. Various protection functions are relatively independent, and protection settings, implementation, blocking conditions, and protection switching can be independently set and configured.
5. The implementation of protection functions does not depend on the communication network, meeting the reliability requirements of power system protection.
