It uses non-contact online monitoring technology, which can collect insulation data in real time without shutdown. It is equipped with a 7-inch touch LCD screen that can directly view real-time monitoring curves and historical data. It supports custom alarm thresholds and early warning functions. When the insulation resistance drops to the preset threshold or shows a downward trend, it can notify operation and maintenance personnel through sound and light alarms, SMS/email push and other methods. It is equipped with a variety of communication interfaces, which can be connected to existing power monitoring systems or cloud platforms to realize real-time remote viewing and data export. The ingress protection rating is IP65, which can adapt to harsh outdoor environments, and supports dual power supply modes of AC220V or DC24V to ensure power supply stability.
The monitoring voltage range is 6kV~35kV, the insulation resistance monitoring range is 0.1MΩ~1000MΩ, and the measurement accuracy is ±3% (reading); the sampling frequency can be adjusted from 1 time/minute to 1 time/hour; the wall-mounted installation size is 320mm×240mm×120mm, and the total weight is 3.2kg; the ingress protection rating is IP65, which can resist dust and water spray; the power supply supports AC85V~265V or DC12V~30V; the local storage capacity supports 1 year of historical data storage, and data can be uploaded through RS485, MQTT, 4G and other methods; it supports a cloud data analysis platform, which can generate insulation status trend reports.
It is suitable for long-term online insulation monitoring of 35kV and below high-voltage distribution systems, substation switch cabinets, high-voltage motors, transformers and other equipment. The core user groups include power grid operation and maintenance companies, large metallurgical and chemical plants, data center high-voltage power distribution departments, railway power supply systems, etc. It can replace traditional regular offline detection, realize 24-hour uninterrupted monitoring, detect insulation hidden dangers in advance, avoid shutdown and power outages caused by sudden insulation faults, and reduce operation and maintenance costs and safety risks.
