An oil storage tank pull rod type oil level monitoring device

Abstract

The invention relates to the technical field of oil level monitoring devices, in particular to a pull rod type oil level monitoring device for oil storage cabinets. The device comprises an oil storagecabinet, a transformer capsule, a first valve pipe and a second valve pipe. The first valve pipe and the second valve pipe are welded to the upper end and the lower end of the oil storage cabinet respectively. The transformer capsule is clamped in the inner cavity of the oil storage cabinet in a left-right direction. A monitoring mechanism is clamped with the top end of the left side of the oil storage cabinet at one end, and extends into the inner cavity of the oil storage cabinet and is clamped with the transformer capsule at the other end. According to the pull rod type oil level monitoring device for the oil storage cabinets, an oil level of the oil storage cabinet can be reliably and accurately displayed through replacing a floating ball type structure by the monitoring mechanism, thereby avoiding false oil level phenomena caused by wrinkles and wrapping, improving the accuracy, and ensuring the normal operation of the transformer. Meanwhile, oil level states of the oil storage cabinet can be remotely checked in real time by realizing the remote display function. The device is simple in structure, convenient and reliable to install and use, and can better protect the transformer.

Description

technical field [0001] The invention relates to the technical field of oil level monitoring devices, in particular to a rod-type oil level monitoring device for an oil storage tank. Background technique [0002] At present, in the power transmission and transformation industry, the oil level gauge used in the transformer capsule oil conservator is basically a float pointer oil level gauge. The pendulum of the oil level gauge is connected to the float ball, and the float ball rises or falls with the liquid level. Therefore, the pointer of the oil level gauge is driven by the swing rod to rotate to indicate the oil level of the transformer oil conservator; [0003] For conventional float type oil level gauges, since the float floats between the liquid surface and the capsule, the capsule is prone to wrinkle during installation or operation. Once the wrinkle occurs at the position of the float, it will wrap the float so that the swing rod cannot The normal swing will cause a f...

[0003] For conventional float type oil level gauges, since the float floats between the liquid surface and the capsule, the capsule is prone to wrinkle during installation or operation. Once the wrinkle occurs at the position of the float, it will wrap the float so that the swing rod cannot Normal swing will cause a false oil level. In addition, the connection between the float and the swing rod is easily damaged. After the float is damaged and enters the oil, a false oil level will also be generated, which will affect the normal operation of the transformer.
