Title:
MULTIPLE-IN-ONE SENSING APPARATUS FOR MONITORING END SCREEN OF TRANSFORMER BUSHING
Document Type and Number:
WIPO Patent Application WO/2023/217053
Kind Code:
A1
Abstract:
A multiple-in-one sensing apparatus for monitoring an end screen of a transformer bushing, comprising an end screen lead apparatus (100) which is connected to a grounding wire of the bushing by means of a mounting bracket (400) and leads out the grounding wire; a sensor assembly (200), provided on the mounting bracket (400) and connected to an oil extraction port of the bushing, and used for detecting and uploading the temperature, pressure, partial discharge current, and hydrogen content of the bushing; a power supply module (300), provided on the mounting bracket (400) and powered by means of coil induction, so as to supply power to the sensor assembly (200). An output end of the end screen lead apparatus (100) is connected to the power supply module (300), and the output end of the power supply module is connected to the sensor assembly (200). The pressure, temperature, hydrogen content, dielectric loss, UHF, and HFCT signals of the transformer bushing can be collected; coil induction power provision is implemented by means of the power supply module (300); the end screen lead apparatus (100) leads out the end screen grounding wire and delivers same to the power supply module (300) for inspection and power provision; the voltage and current required by the sensor assembly (200) is converted by means of the power supply module (300). The installation and inspection are convenient, maintenance and repair are reduced, and the service life is prolonged.
