Introduction to oil level gauge

The oil level gauge is used to indicate and monitor the oil level of the power transformer oil storage tank. The indicator and sensor of the oil level gauge are connected by a hose, so the indicator can be installed in a safe and convenient place for observation.

The oil level gauge is detected based on the position of a float, which drives a connecting rod in a flange mounting part installed on the oil storage tank with bolts. The connection between the two parts is sealed with a soft metal corrugated pipe, which transmits the rotation of the float connecting rod to the hydraulic system of the indicating instrument. The hydraulic system consists of two pairs of corrugated pipes and connecting pipes. A pair of corrugated pipes are connected to a flange mounting piece, and the movement of the connecting piece is transmitted to the second pair of corrugated pipes in the indicating instrument through the connecting pipe.

This series of products is mainly suitable for oil immersed fully sealed transformers, installed on the upper part of the transformer oil tank cover to display the oil level inside the tank. When a blue mark appears in the upper window of the oil level gauge, it indicates that the oil level is normal and above the tank cover; When a red mark appears, it indicates an abnormal oil level, with the oil level below the box cover. It is necessary to add oil appropriately. The upper M40 × 1.5 thread of this product can be used as an oil injection edge pipe, pressure relief valve, vacuum pumping and other interfaces.

The tubular oil level gauge is composed of seamless steel pipes, buoy indicating devices, sight windows, and an upper cover or pressure valve; The window adopts a thick walled glass tube built-in structure. It can display the specific oil level within 30mm below the box cover, and the oil level display is true, accurate, and without any false oil level phenomenon. The oil level display position can be set according to user requirements, and only needs to be requested by the user when placing an order. It is normal to set the oil level display position above the box cover for products without special requirements. When the oil level is above the box cover, the float display is all blue, indicating that the oil level is normal; The window adopts an embedded structure with the same external dimensions as the pipe diameter, effectively preventing accidental collision and damage. The window has a 360 ° C viewing angle. This product is sealed with an O-ring through M52 × 2 threaded connection, ensuring reasonable compression of the sealing ring and effectively preventing ultraviolet radiation, making the rubber ring have a longer lifespan, safety and reliability, and no leakage. Before leaving the factory, a 200KPa pressure leak test is conducted. The external surface is electrostatically sprayed, meeting the three protection requirements.
