?Product Overview

The CKSK800 Intelligent Operation and Maintenance Measurement and Control Device is primarily installed in 10kV Ring Main Units and high/low voltage complete cabinets. It can perform intelligent data collection for Ring Main Units, gathering current, voltage, zero-sequence, switch status, open/close position, thermal diagnosis, environmental conditions, temperature, and humidity, among others. It also supports bus temperature detection, remote intelligent control, and communication functions. Furthermore, it can conveniently and reliably connect to other systems for communication. By leveraging big data and internet technology, based on private networks or internet platforms, it can provide efficient and diverse functional services offered by remote monitoring service centers, such as online remote diagnosis, product remote upgrades, and internet monitoring services.

?Product Features

The CKSK800 backup automatic protection device utilizes the STM32F767IGT6 32-bit ARM+DSP M7 dual-core high-speed controller, which is equipped with 32M SDRAM and 32M FLASH, enhancing both operational speed and stability. It employs ADI's AD7606 for the acquisition of current, voltage, and zero sequence current, and features include switch status, open/close position, thermal diagnosis, environmental monitoring, temperature and humidity tracking, bus temperature detection, remote intelligent control, and communication capabilities.
