Description

Technical Field

[0001] This utility model relates to the field of substation detection technology, specifically to a comprehensive monitoring device and system for fire protection systems. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receiving and distributing electrical energy. For example, a substation within a power plant steps up the voltage of electricity generated by generators before feeding it into the high-voltage power grid. Under various environmental factors, the performance of electrical equipment used in substations can deteriorate, and even power outages can occur. Online monitoring of electrical equipment allows for timely detection of its performance status and assessment of insulation conditions based on trends in dielectric losses, enabling online auxiliary diagnosis and reducing the workload of manual identification and judgment.

[0003] Currently, substation intelligent integrated monitoring devices are built using motherboards from different manufacturers, resulting in various integrated monitoring products such as core monitoring, capacitive monitoring, chromatographic monitoring, fire protection monitoring, density monitoring, and partial discharge monitoring. Because different manufacturers provide different products, each platform requires different personnel for maintenance, increasing manpower and material costs. Furthermore, the different system platforms introduced by each platform present different potential risks. Developing an integrated fire protection system monitoring device that can be integrated into a single core platform could improve product standardization, reduce material and personnel consumption, and increase product reliability. Therefore, it could be widely used in substation auxiliary integrated monitoring and has broad application prospects.

[0004] In view of the above, this application is hereby submitted. Utility Model Content
