Abstract
The invention discloses an oil level indicating device for an oiled paper capacitance type bushing and the oiled paper capacitance type bushing. The indicating device comprises a bushing oil conservator, and a connecting sleeve is installed at the bottom of the bushing oil conservator; the pressure monitoring device is arranged on the connecting sleeve, and the end part of the pressure monitoring device is connected with a local cabinet; a power supply device, a signal transmitting device, a pressure oil level conversion device, an A / D rotating device and a communication device are arranged in the local cabinet, the pressure monitoring device is connected with the signal transmitting device, one end of the power supply device is connected with the pressure monitoring device, and the other end of the power supply device is connected with the signal transmitting device, the pressure oil level conversion device, the A / D rotating device and the communication device. By installing the pressure monitoring device on the connecting sleeve, the pressure change in the casing expansion tank can be measured in real time, then the signal transmitting device processes an oil pressure signal and transmits the oil pressure signal to the pressure oil level conversion device, the pressure oil level conversion device can accurately convert the pressure signal into oil level information, and the monitoring accuracy is improved.
