ADVP-400E series digital protection and monitoring device

Overview

The ADVP-400E series low-voltage integrated protection and monitoring device primarily targets various primary equipment operating at voltage levels ranging from 6kV to 35kV. It is an intelligent device that integrates protection, measurement, control, and communication functions, and is primarily suitable for the protection and monitoring of substation and industrial and mining enterprise auxiliary power systems.

The ADVP-400E series products include protection and monitoring devices for main transformers, motors, capacitors, lines, and other equipment, primarily suitable for 66kV and below power transformation and distribution stations.

Key Features:

1. Adopt advanced digital signal processing technology (DSP);

2. Hardware standardization, with a full range of protection hardware that is universally applicable; high-reliability hardware and software redundancy design endows the device with strong anti-interference performance;

3. Fully sealed aluminum chassis with a back-inserted structure, achieving a sealing level of IP20;

4. LCD display in Chinese, fully menu-driven operation, decimal continuous setting;

5. The transmission test function allows for a linkage inspection of the outlet circuit;

6. Perfect software and hardware self-checking function. If any abnormality is detected, the exit will be locked and an alarm signal will be sent, displaying the fault content;

7. The online monitoring and recording function can display various protection and measurement parameters, such as current, voltage, switch status, etc. A high-reliability and large-capacity ferroelectric serial memory is used to permanently store a large number of device events;

8. The communication network adopts safe and reliable industrial Ethernet technology, with multiple devices connected to the host computer or communication management machine to form a communication network, enabling centralized control of the system and achieving functions such as telemetry, telecommand, and remote control;

9. All protection functions (including non-electric quantity protection) can be independently selected for the export mode and have soft pressure plate activation/deactivation;

10 .Four sets of fixed values can be set to adapt to various operating conditions;

11. It features a variety of functional modules for selection, including input and output expansion, operation circuits, DC analog input, 4~20mA DC analog output, temperature resistance measurement, etc.

11. The input power supply is compatible with both AC and DC;

12. Equipped with a standard Ethernet communication interface, and an optional RS485 communication interface.
