product overview

According to《Q_GDW 534-2010Technical Guidelines for Online Monitoring System of Substation Equipment 《QCSG11401-2010Gas insulated metal enclosed switchgear（GIS）Design requirements for partial discharge ultra-high frequency detection technology specifications.Partial discharge is the electrical breakdown of a localized area in electrical insulation, typically characterized by burrs or sharp edges on the surface of a conductorSF6If the gas contains metal particlesGISIf the surface of the insulation component is not smooth enough or contains dust impurities, if the weld seam on the inner surface of the shell is uneven or rough, especially when the contact resistance of the switch contact increases due to oxidation during operation, it will cause electric field distortion and partial discharge.

GIS partial discharge online monitoring device (WINFOSS-X6)superviseThe task of testing and diagnosis is to understand and master the operating status of equipment, including adopting various detection, measurement, monitoring, analysis, and discrimination methods, combining the history and current situation of the system, considering environmental factors, evaluating the operating status of equipment, determining whether it is in a normal or abnormal state, displaying and recording the status, issuing alarms for abnormal states, so that operators can handle them in a timely manner, and providing information and preparing basic data for equipment fault analysis, performance evaluation, rational use, and safe work. Realize state maintenance of switch insulation, reduce power outage time and save management and maintenance costs.

When partial discharge occurs, the electromagnetic wave signal is based onGISThe structure undergoes repeated propagation, reflection, refraction, delay, attenuation, and other phenomena, which are radiated to the outside through the bowl shaped insulator (insulation component). pass throughGISThe electromagnetic waves leaked from insulators are detected by high-sensitivity built-in or external sensors. Detecting through sensorsGISThe electromagnetic wave signal excited by internal partial discharge is detected through filtering, RF preamplifier, and detector, and then sampled, stored, processed, and analyzed by a high-speed data acquisition module. The data processed by the on-site monitoring unit is transmitted to the main processor unit through optical fiber; The main processor unit builds a fault mode database based on the data sent from the on-site monitoring unit through the fault diagnosis expert system running on it, andGISDiagnose the insulation status and display discharge fingerprint characteristic data in multiple ways; The partial discharge historical measurement data stored on the main processor unit can be queried by staff and remote management systems.

GISPartial discharge online monitoring device (Winfoss-X6)）Can be monitored and recorded online at any timeGISAnalyze and judge the operating status of the equipment using a diagnostic system. equalGISWhen an exception occurs, the system quickly collects and processes fault data, while completing functions such as online calculation, storage, statistics, alarms, analysis reports, and remote data transmission.
