Information Introduction

Characteristics of 810 series microcomputer protection device products

*Adopting 32-bit high-performance DSP processor, 32-bit logic processor, and 16 bit high-speed A/D; In terms of software and hardware design, sufficient anti-interference measures are taken. The 6U fully enclosed chassis, overall panel, and strict separation of strong and weak electricity greatly improve the anti-interference ability of the device, and the external electromagnetic radiation also meets relevant standards;

*A complete A/D sampling circuit self-test can avoid device misoperation caused by A/D sampling errors; Open circuit self-test can accurately detect any open circuit disconnection or open circuit breakdown fault, issue an alarm, and reliably lock protection; Fixed value self-test can detect errors in the fixed value storage area, fixed value exceeding limits, etc;

*Equipped with ± 5V and ± 15V power self-test function, the device sends an alarm message and locks protection when the power voltage is abnormal;

*The visualized logic development tool VLD, in which all protection logic is composed of different visualized flexible relays, achieves complete transparency design of microcomputer protection;

*Adopting a fully Chinese Windows menu mode with clear structure, all device operations can be completed through menu prompts, making it easy to use;

*There are two options to choose from: "drive by channel" and "drive by protection". This not only allows for the inspection of the wiring of each tripping circuit on site, but also enables the inspection of the tripping circuit of the protection without applying current or voltage;

*On site, without the conditions for protective function testing, the device can conveniently conduct communication point-to-point testing by sending relevant protection action information, alarm information, etc. to the automation monitoring system through the communication point-to-point menu;

*It can print the amplitude and phase of the normal current and voltage on each side, making it convenient for users to verify the polarity of the current and voltage on each side when the transformer is put into operation.
