B10 Bushing Monitor - Beijing Kanggaote Instruments and Equipment

Product introduction

> dielectric loss、capacitance、magnitude of partial discharge > dissolved hydrogen, oil temperature、oil pressure At present, the running state of bushing mainly depends on the preventive test carried out during periodic power outage. After the bushing test, the operation and maintenance personnel know nothing about the running state of bushing until the next test or failure, and there is a monitoring "blind spot".

Multi - parameter condition of less oil equipment structural diagram of the online monitoring equipment is mainly composed of three parts: a signal acquisition unit, a control cabinet unit and a data analysis unit.

> The signal acquisition unit is responsible for sampling data of H2, oil temperature and oil pressure,dielectric loss, capacitance and magnitude of partial discharge.

> The data transfer unit will sample data for calculation, display, data relay and upload.

> The data analysis unit is responsible for data analysis, warning and diagnosis.

The visualized free analysis scenario is developed in the background. Based on big data accumulation and artificial intelligence training, remote monitoring, risk assessment and intelligent diagnosis of equipment running state can be realized.

Electrical Parameter Monitoring

> Capacitance: 100pF ~ 50000pF, the error is not more than ±(standard reading ×0.5%+1pF)；

> Dielectric loss factor: 0.001-0.3, the error is not more than ±(standard reading ×1%+0.001)；

> Magnitude of partial discharge: Minimum measurable <50pC, 0.5MHz ~ 30MHz bandwidth >2MHz, transmission impedance >5mV/mA, linearity error <15%.

Physicochemical Parameter Monitoring

> dissolved hydrogen：20ppm~5000ppm, error <20ppm;

> oil temperature：-40℃~105℃, error <±1°C;

> oil pressure：0MPa~1.0MPa, error <0.1kPa.
