Problems solved by technology

[0004] However, the above-mentioned functional components are scattered and independent structures, occupying a large area in oil-immersed electrical equipment
Moreover, during the operation of oil-immersed electrical equipment, it is necessary to monitor and control multiple functional components to ensure the safe operation of oil-immersed electrical equipment, which will lead to low work efficiency
Moreover, the existing oil level gauge usually needs to be powered on for detection, which has certain requirements for the use environment

Abstract

The invention discloses an oil level gauge, and belongs to the technical field of oil-immersed electrical equipment. The oil level meter comprises an oil pipe, a floater, a magnet, a thermometer, a magnetic liquid level meter and a pressure relief valve. The floater is slidably arranged in the oil pipe, and the magnet is fixedly arranged on the floater; the first end of the oil pipe is provided with a connecting part used for being connected with oil-immersed electrical equipment, and the pressure relief valve is arranged at the second end of the oil pipe and detachably connected with the oil pipe in a sealed mode; a blind pipe is arranged on the inner wall of the oil pipe, and the thermometer is arranged in the blind pipe and measures the temperature of oil in the oil pipe; a mounting cavity is further formed in the outer wall of the oil pipe, the magnetic liquid level meter is arranged in the mounting cavity, a red overturning part and a white overturning part in the magnetic liquid level meter are driven to overturn according to the position of the magnet in the oil pipe, and the height of oil in the oil pipe is displayed; and a thermometer observation window and an oil level observation window are arranged on the oil pipe. The oil level gauge can realize high integration of multiple functions of oil level display, temperature display, oil injection, pressure release and the like, reduces the structural size, and can be used in an electroless environment.

Description

technical field [0001] The present disclosure relates to the technical field of oil-immersed electrical equipment, in particular to an oil level gauge. Background technique [0002] Oil-immersed electrical equipment is a common equipment in the power system. It has functions such as oil level monitoring and temperature monitoring during operation. In addition, it can perform pressure relief during oil injection and discharge and failure, which is essential for the safe and reliable operation of oil-immersed electrical equipment. few basic conditions. [0003] Traditional oil-immersed electrical equipment usually includes functional components such as oil level gauge, thermometer, oil injection pipe, and pressure relief valve. It can be used to realize the function of oil injection and discharge, and the pressure relief valve can be used to release the pressure in case of failure. [0004] However, the above functional components are all dispersed and independent structures...
