Device Introduction:

The DNT-5500 series is a protection and measurement device developed and manufactured by our company specifically for high-voltage switchgear of 10KV and below. This series of microcomputer protection devices has the characteristics of easy operation, distributed installation, etc. It highlights the solution to the long-term reliable operation of the series devices in harsh environments, compatibility issues with conventional control, measurement, and signals, and the problems of rapid, simplified, intelligent, and habitual system design, debugging, and operation. This series of protective devices can be directly installed on high voltage switchgear or outdoor terminal boxes, replacing traditional relay protection and instrument monitoring on high and low voltage switchgear, greatly improving the intelligence level of high and low voltage switchgear.

Scope of application:

This series of products is suitable for primary equipment such as 10KV and below high and low voltage switchgear, box type substations, outdoor switches, etc., to complete protection and measurement functions. It is widely used in high and low voltage switchgear manufacturing plants, power, petroleum, chemical, coal, construction and other industries.

Main features:

Chinese characters and graphic display: This device uses a Chinese LCD to cyclically display the required electrical quantities such as current, voltage, and power. It displays primary images, remote signaling, and other information through graphics, and displays various information about protective actions on the screen

Information storage: It has the ability to record the latest 255 event information and has a power-off hold function. The information can be viewed in the report record

Anti interference performance: The unit chassis adopts a metal enclosed structure to reduce electromagnetic interference to the device. Fast transient voltage suppression devices are selected to make the device highly compatible with electrical collisions

Strong universality: The working and operating power supply of the device is AC and DC universal, and will not stop working and protecting due to DC system failures

High performance CPU: equipped with 32-bit high-performance processing chip, large capacity RAM and FlashMemory Strong data operation, logical processing, and information storage capabilities, high reliability, and fast running speed.
