ADVP-400 series digital protection and monitoring device

Overview

The ADVP-400 series low-voltage integrated protection and monitoring device primarily targets various low-voltage primary equipment ranging from 0.4kV to 10kV, serving as an intelligent device that integrates protection, measurement, control, and communication. It is primarily suitable for the protection and monitoring of power systems in power plants, substations, and industrial and mining enterprises. The ADVP-400 series products encompass protection and monitoring devices for workshop transformers, motors, capacitors, lines, and other equipment, and are primarily applicable to 10kV distribution stations.

Key Features:

1. Adopt advanced digital signal processing technology;

2. Hardware standardization, with a universal protection hardware across the entire series, and a highly reliable hardware and software redundancy design, the device exhibits 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 high-capacity ferroelectric serial memory is used to permanently store a large number of device events;

8. The communication network adopts safe and reliable high-speed fieldbus 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-electricity protection) can be independently selected for export methods 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. The input power supply is DC220V.
