Abstract

The invention provides an intelligent oil level gauge for a transformer bushing, comprising: a measuring piece, a transmission mechanism, a pointer dial, a protective cover and a controller; a pressure temperature sensor is arranged on the surface of the transmission mechanism, and an oil level measurement sensor is arranged on the surface of the pointer dial , the controller sends each of the acquired data to an external monitoring device and sends an alarm signal to the monitoring device when any one of the data is abnormal. The invention uses the magnetic field force between the pointer dial and the transmission mechanism to feed back the displacement change of the measuring piece as the oil level changes to the pointer dial, and automatically reads the oil level information through the oil level measuring sensor arranged on the outer surface of the pointer dial , to ensure the accuracy of oil level measurement, and use the communication unit in the controller to transmit the data information obtained by the oil level measurement sensor to the external monitoring equipment, which reduces the cost of on-site operation and maintenance and provides the work of on-site operation and maintenance personnel It provides great convenience and ensures the safe and reliable operation of the power grid.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment insulation, in particular to an intelligent oil level gauge for transformer bushings. Background technique [0002] For oil-paper insulating bushings of high-voltage transformers, the oil level and internal pressure are the key early-warning state quantities of its operating status, and oil level inspection is also one of its inspection items. Casing defects will cause the dissolved gas in the oil to expand and the oil level to rise. By monitoring the oil level and internal pressure of the casing, the internal fault of the casing can be effectively judged and the fault warning can be realized. At present, domestic and foreign technical research on gas pressure on-line monitoring and internal pressure on-line monitoring of large oil field equipment such as power transformers has become relatively mature and has been widely used. There are relatively few studies on online monitoring ...
