YT-GZDW series microcomputer intelligent DC power supply screen

System Overview

YT-GZDW microcomputer DC power cabinet is suitable for various power plants and substations, as a high-voltage circuit breaker for opening and closing, relay protection, emergency lighting and other places that require DC power supply. In unmanned substations, the monitoring unit of the DC power supply system is connected to the RTU system of the substation, and can upload the operating parameter information, operating status, alarm information, etc. of the DC system to the monitoring center. Implement the "four remote" function of the system.

This series of microcomputer intelligent DC power supply screens adopts computer control technology, greatly improving the reliability, controllability, flexibility, and intelligence of the system, creating conditions for unmanned or less manned operation. Meeting the requirements of the power system for low-voltage DC power supply is the development trend and mainstream of modern control operation power supply.

The product has undergone type testing and technical appraisal by the Quality Inspection and Testing Center for Power Equipment and Instruments in the Power Industry. All indicators meet the technical requirements of ZBK45017-90 "General Technical Conditions for DC Screens in Power Systems", LS (W) 30-40JT "Technical Conditions for Microcomputer Controlled DC Power Supply Cabinets", DL/T459-2000 "Technical Conditions for Ordering DC Power Supply Screens (Cabinets)" and other standards, and the product quality has reached the international advanced level.
