Description

Technical Field

[0001] This utility model relates to the field of transformer oil level verification technology, specifically to an oil-immersed transformer oil level verification device. Background Technology

[0002] Currently, the power industry primarily uses pointer-type oil level gauges for oil-immersed transformers. Because these equipment are often outdoors, they are susceptible to various factors, leading to discrepancies between the gauge readings and the actual levels. During high-load operation, maintenance personnel struggle to accurately determine the true oil level in the transformer's conservator. Internal malfunctions in the level gauge can cause false alarms and premature shutdowns, posing a significant safety hazard to the transformer's safe operation. Therefore, how to safely, quickly, and accurately determine the true oil level in the transformer's conservator during emergencies is a crucial technical problem that power industry equipment maintenance personnel must solve. Utility Model Content

[0003] The main purpose of this utility model is to provide an oil level verification device for oil-immersed transformers, which solves the problem that existing oil-immersed transformers mainly use pointer-type oil level gauges to measure the oil level, and the measured oil level value deviates from the actual oil level value.

[0007] As a further improvement of this utility model, the support base includes a support chassis and support legs spaced apart on the support chassis; an adjustment cavity is formed between the support legs; and the support member passes through the support chassis and is inside the adjustment cavity.

[0008] As a further improvement of this utility model, the support member includes a support vertical rod and a support horizontal rod disposed on the support vertical rod; the support vertical rod passes through the chassis and is located in the adjustment cavity; the support horizontal rod is provided with a connecting ear plate.

[0011] As a further improvement of this utility model, the measuring component includes a pull rope movably connected to the sliding roller and a measuring tape connected to the pull rope; the indicator mark is located at the zero mark of the measuring tape.

[0012] The beneficial effects of this utility model are reflected in:

[0013] By setting up a support base and support components to support the measuring tube, one end of the measuring tube is made to exceed the height of the transformer oil conservator, and the other end is connected to the oil tap on the transformer. After the oil in the transformer is introduced into the measuring tube, the floating ball in the measuring tube moves up to match the liquid level in the oil conservator. The floating ball is indicated by an indicator mark. The height of the floating ball from the ground is obtained according to the scale on the measuring component. The height of the transformer from the bottom of the oil conservator is then subtracted to obtain the oil level inside the oil conservator. The actual oil level is obtained by externally verifying the liquid level inside the oil conservator. Attached Figure Description

[0027] Further, see Figure 3 , 4 The adjusting component 3 includes a guide sleeve 301 mounted on the support chassis 101 and an adjusting sleeve 302 rotatably mounted on the guide sleeve 301. The guide sleeve 301 is connected to the adjusting cavity 103, and the adjusting sleeve 302 is threadedly connected to the support vertical rod 201.

[0028] Preferably, the guide sleeve 301 is a hollow cylinder with two openings, and the guide sleeve 301 is coaxially arranged with the through hole.

[0029] Preferably, the guide sleeve 301 has a raised edge 11 at the end away from the supporting chassis 101, and the adjusting sleeve 302 has a groove 12, which is slidably connected to the raised edge 11.

[0030] Preferably, the inner wall of the adjusting sleeve 302 is provided with internal threads, and the outer wall of the supporting vertical rod 201 is provided with external threads.

[0031] In the above configuration, the support rod 201 passes through the adjusting sleeve 302 and the guide sleeve 301 and is located in the adjusting cavity 103. The adjusting sleeve 302 is threadedly connected to the support rod 201. By rotating the adjusting sleeve 302, the support rod can be moved up or down under the action of the thread. During the adjustment process, one hand holds the adjusting sleeve 302 and the other hand holds the support rod 201. When it is necessary to adjust the support rod 201 to move up, the hand holding the support rod 201 will lift it up.

[0032] Further, see Figure 1 The connector 4 includes a connecting sleeve 401, one end of which is fixedly connected to the support vertical rod 201 and is provided with a buckle 402, and the other end passes through the buckle 402 to form a fixed ring to connect the measuring tube 6; the sliding member 5 includes a sliding roller 501 rotatably disposed in the connecting ear plate 10.

The measuring tube 6 is connected to the oil inlet at the lower end of the transformer. After the valve 14 is opened, the oil enters the hose. According to the principle of communicating vessels, the oil in the measuring tube 6 moves up to the same height as the oil in the oil tank on the transformer. At this time, the float ball 8 moves up accordingly. The indicator mark 9 on the measuring tape 702 is aligned with the float ball 8. The height H1 of the float ball 8 from the ground is obtained by measuring the scale on the measuring tape 702.

At this time, the height of the floating ball 8 is consistent with the liquid level in the oil conservator. The pull rope 701 is pulled to move the measuring tape 702 so that the indicator mark 9 is aligned with the floating ball 8, and the scale H1 of the measuring tape 702 on the ground is read.

[0040] The height difference h between H1 and H is the actual oil level in the oil reservoir.
