Problems solved by technology

[0003] However, because the caliber of the oil drain valve is small and the distribution range of the sensors should be as wide as possible, the existing partial discharge detection mechanism cannot meet the above requirements.

Abstract

The invention provides a disc-shaped unscrewing mechanism, which comprises a rotary fixed shaft assembly, an unscrewing mechanism and a blade mechanism. In the initial state, the blade mechanisms areall contracted to be a straight line type, thereby being beneficial to reducing the volume; in the unfolded state, a first step gear and a second step gear are driven to rotate through the rotation ofa straight bevel gear, the first step gear and the second step gear are respectively meshed with circular gears in a first sheet gear set and a second sheet gear set in sequence in the rotating process, so that the unfolding blades fixedly arranged on the circular gears are unfolded in sequence. In addition, the invention also provides a partial discharge detection device containing the disc-shaped unscrewing mechanism.

Description

technical field [0001] The invention relates to a disk-shaped unscrewing mechanism and a partial discharge detection device. Background technique [0002] At present, UHF antenna design is one of the most important links in UHF detection technology. The quality of its performance can directly have a very large impact on the results of UHF detection. At present, the installation method of the receiving antenna at home and abroad is mainly to put the sensor device deep into the transformer through the oil discharge valve port of the transformer. When using this method, it will not affect the normal operation of the transformer. To sum up, since the transformer box has a shielding effect on the partial discharge UHF signal, and the transformer oil will not interfere with the sensor detection, it is the strongest anti-interference and the most sensitive method among the three methods to go deep into the transformer. OK [0003] However, because the caliber of the oil discharg...
