Problems solved by technology

When a false oil level occurs, the oil level of the oil conservator can be judged and estimated by indirect means such as infrared imaging diagnosis technology and oil pressure measurement. However, the above methods are often not accurate due to the constraints of environmental factors and the accuracy of measuring instruments. The actual oil lev

Example Embodiment

[0021] The present invention will be described in detail below with reference to the drawings and specific embodiments:

[0022] Such as figure 1 Shown is a specific embodiment of the present invention. The device for measuring the oil level of the oil conservator of the oil-immersed transformer includes an upper section measuring rod 1, a middle section measuring rod 2, a lower section measuring rod 3, a float 7, a tripod 4 and Hose 5. The upper section measuring rod 1, the middle section measuring rod 2 and the lower section measuring rod 3 are arranged as hollow insulating rods, and the three are detachably connected to form a hollow straight rod. In this embodiment, the upper section measuring rod 1, the middle section A threaded connection is adopted between the measuring rod 2 and the lower section measuring rod 3. The red float 7 is placed in the hollow straight rod, and the upper section measuring rod 1 is provided with a scale line 12 and a corresponding observation win...

Abstract

The invention discloses a live line measurement device for the oil level of an expansion tank of an oil-immersed transformer. The live line measurement device comprises an upper-section measuring rod, a middle-section measuring rod, a lower-section measuring rod, a float, a tripod and a hose. The upper-section measuring rod, the middle-section measuring rod and the lower-section measuring rod are hollow insulation rods and are detachably connected to form a hollow straight rod, the float is arranged in the hollow straight rod, the tail end of the bottom of the lower-section measuring rod is fixed to the top of the tripod and connected with one end of the hose, the other end of the hose is connected with an oil injection and drain valve of the oil-immersed transformer through a connection port, and the side face of the upper-section measuring rod is provided with scale marks and a corresponding observation window. According to the principle of communicating vessels, the live line measurement device can be used for measuring the actual height of the oil level in the expansion tank of the transformer accurately, and is simple to operate, convenient to carry and good in safety.

Description

technical field [0001] The invention relates to the field of transformer auxiliary equipment, in particular to an oil-immersed transformer oil conservator oil level charged measuring device. Background technique [0002] At present, oil-immersed transformers are generally used in large-scale transformers. As the main accessory of oil-immersed transformers, oil pillows are used to store transformer oil. Due to changes in operating load or ambient temperature, transformer oil expands with heat and contracts with cold, that is, when the temperature rises , the volume of the oil expands, and the oil level of the oil conservator increases; when the temperature decreases (the load decreases), the volume of the oil shrinks, and the oil level of the oil conservator decreases accordingly, and the oil conservator makes the oil level of the transformer body and main components within Change within the specified range, so as to ensure that the inside of the transformer oil tank basicall...
