1 Overview

The tubular oil level gauge is mainly suitable for oil-immersed fully sealed transformers, which are installed on the upper part of the transformer fuel tank cap and show the oil level in the fuel tank. When the blue mark is displayed in the upper part of the oil level gauge, the oil level is normal, the oil level is above the cover; when the red mark is displayed, the oil mark is abnormal, and the oil level is below the cover, and the oil should be properly replenished. The upper M40×1.5 thread of this product can be used as the interface of oil injection side pipe, pressure release valve and vacuum pumping.

2, structure and characteristics

The tubular oil level gauge consists of a seamless steel pipe, a buoy indicating device, a window and an upper cover or a pressure valve; the window is constructed with a thick-walled glass tube. It can display the specific oil level within 30mm of the lower part of the lid. The oil level shows true, accurate and no false oil level. The oil level display position can be set according to user requirements, and only needs to be submitted by the user when ordering. The oil level display position of the product without special requirements is set above the cover. Normally, when the oil level is above the cover, the buoy display is all blue, indicating that the oil level is normal; the window adopts the embedded structure, the outer dimensions Same as the pipe diameter, effectively prevent accidental bump damage, 360°C angle of view of the window, this product is sealed by O-ring with M52×2 thread connection to ensure reasonable compression of the sealing ring, effectively prevent ultraviolet radiation and make the rubber ring last longer. , safe and reliable, no leakage, 200KPa pressure leak test before leaving the factory. The external surface is electrostatically sprayed to meet the requirements of three defenses.

3. Installation, use and maintenance

The oil level gauge is installed in the upper part of the transformer tank cover. When the fuel tank is manufactured, the flange seat provided by our company will be welded to the opening of the cover as shown in the figure (with inner weld seam, the diameter of the cover opening is 60mm), the weld joint should be securely leaked, and the window direction should be selected. The bolts can be firmly connected to the mounting flange (Note: the seal should not be scratched, it is best to apply a little oil on the outer surface).

When filling a small amount of oil, oil can be injected at the top port of the oil level gauge. Unscrew the top cover or pressure relief valve on the top of the oil level gauge and slowly fill the oil until the oil level is higher than the transformer cover. At this time, the buoys in the window should all be blue, indicating that the oil level is normal.

The equipment can be used to overhaul the oil level gauge, check whether the oil level meter window glass is damaged or stained, and replace it in time. If other auxiliary functions are used, the upper cover of the oil level gauge can be unscrewed, and other foreign objects can not be directly inserted into the upper part by M40×1.5 thread connection to avoid damage to the buoy and other parts.

5. Product model: YW1 is a pressure relief valve type, and YW2-35/25 is a pressure relief valve type. The pressure relief valve has an effective diameter of 25mm and an opening pressure of 35KPa.

Overview of Dongguan Juke brand transformer oil level gauge

This series of products is mainly suitable for oil-immersed fully sealed transformers, installed in the upper part of the transformer tank cover, showing the oil level in the fuel tank. When the blue mark is displayed in the upper part of the oil level gauge, the oil level is normal, the oil level is above the cover; when the red mark is displayed, the oil mark is abnormal, and the oil level is below the cover, and the oil should be properly replenished.

3. Installation, use and maintenance

The oil level gauge is installed in the upper part of the transformer tank cover. When the fuel tank is manufactured, the flange seat provided by our company is welded to the opening of the cover as shown in the figure (using the inner weld, the opening size of the cover is ø60mm), the weld is firm and there must be no leakage, and the direction of the window is selected. The bolts can be firmly connected to the mounting flange (Note: the seal should not be scratched, it is best to apply a little oil on the outer surface).

When filling a small amount of oil, oil can be injected at the top port of the oil level gauge. Unscrew the top cover or pressure relief valve on the top of the oil level gauge and slowly fill the oil until the oil level is higher than the transformer cover. At this time, the buoys in the window should all be blue, indicating that the oil level is normal.
