[0002] Transformers are very important equipment in power systems, and the oil in their tanks plays a role in insulation, cooling, and protection. However, due to various reasons, oil leaks may occur in the tanks, which may cause equipment failure or even accidents if not discovered and handled in time.

[0003] At present, due to the different models and depths of transformer oil tanks on the market, different detection devices or methods are often required, which leads to the complexity of detection work and increased costs. For some deeper oil tanks, existing detection devices may not be able to reach the bottom, and thus cannot accurately detect oil leakage. Secondly, when the oil level in the tank is not full, traditional detection devices often do not work well. Due to the low oil level, the sensing mechanism of the detection device may not be triggered, or the detection result may be inaccurate, which is prone to misjudgment or missed judgment.

[0004] Therefore, it is necessary to provide a transformer tank oil leakage detection device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a transformer oil tank oil leakage detection device provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 An enlarged schematic diagram of part B is shown; Figure 4 for Figure 3 A transformer oil tank oil leakage detection device comprises: an airtight cover 1, a hard tube 2 is slidably connected inside the airtight cover 1, an air bag 3 is fixedly connected to the bottom of the hard tube 2, a pressure detector 4 is installed on the upper surface of the hard tube 2, a hose 5 is fixedly connected to the top of the hard tube 2, a two-way air pump 6 is fixedly connected to the other end of the hose 5, an air inlet pipe 7 is fixedly connected to the front of the two-way air pump 6, a filter screen 8 is installed on the air inlet pipe 7, an air outlet pipe 9 is fixedly connected to the back of the two-way air pump 6, a control line 10 is fixedly connected to the right side of the two-way air pump 6, a controller 11 is fixedly connected to the other end of the control line 10, a display screen 12 is installed on the controller 11, and a two-color lamp 28 is installed on the top of the airtight cover 1. The detection device can perform effective detection even when the oil level in the tank is not full, avoiding misjudgment caused by oil level problems and ensuring the accuracy of the detection results.

[0021] A connecting plate 13 is fixedly connected between the hard tube 2 and the hose 5, a first airtight pad 14 is fixedly connected to the top of the airtight cover 1, a sliding ring 15 is slidably connected to the surface of the hard tube 2, and a second airtight pad 16 is fixedly connected to the inner surface of the sliding ring 15. The first airtight pad 14 is matched with the second airtight pad 16. When the depth of the oil tank is too deep or too shallow, it is only necessary to move the airtight cover 1 to a proper position, and then move the sliding ring 15 to make the first airtight pad 14 close to the second airtight pad 16 for secondary sealing to ensure airtightness to adapt to oil tanks of different depths.

[0022] A sensor 17 is fixedly connected to the bottom end of the hard tube 2, an anti-skid ridge 18 is fixedly connected to the side surface of the airtight cover 1, and two suction cups 19 are fixedly connected to the bottom of the two-way air pump 6. The sensor 17 can sense the oil temperature, and the suction cups 19 can ensure the stable installation of the two-way air pump 6.

[0023] The controller 11 is provided with two air pump control buttons 20 and an air pump start button 21. The two air pump control buttons 20 control the two-way air pump 6 to inflate or inhale the airbag 3. When the detection device needs to be taken out, the airbag 3 needs to be deflated by inhalation.

[0024] The controller 11 is provided with a control unit 22, an alarm unit 23, and a communication unit 24. The control unit 22 controls the start-up of the two-way air pump 6, the alarm unit 23 controls the color of the two-color light 28, and the communication unit 24 can transmit the monitoring data to the staff's mobile phone or other terminals.

[0025] The controller 11 is provided with a data storage unit 25, a power supply unit 26, and a data display unit 27. The detected data is stored in the data storage unit 25. The power supply unit 26 controls the amount of power provided to the controller 11. The detected data can be displayed on the display screen 12 through the data display unit 27.

[0026] The working principle of a transformer oil tank oil leakage detection device provided by the utility model is as follows:

[0027] When the detection device is used to detect oil leakage in the transformer oil tank, the hard tube 2 and the airbag 3 are first extended into the oil tank through the oil tank filling port, the airbag 3 is immersed in the refrigeration oil, and the airtight cover 1 is pressed to make the inside of the oil tank in a sealed state. An airtight suction cup is provided at the bottom of the airtight cover 1. The two-way air pump 6 is started by the controller 11 to inflate the airbag 3, so that the air pressure inside the oil tank increases. If there is an oil leakage, it can be directly and more intuitively observed. If the oil tank is not full of oil, the airbag 3 is inflated first. After the inflation is completed, the data detected by the pressure detector 4 is recorded, and then recorded again after a period of time. If there is a difference, it proves that oil leakage may occur when the oil tank is full of oil, and the two-color light 28 will light up in different colors according to the detection results.

[0028] Compared with the related art, the transformer oil tank oil leakage detection device provided by the utility model has the following beneficial effects:

[0029] The detection device does not need to be replaced for oil tanks of different depths, which reduces operation time and labor costs. It can detect whether the oil tank is leaking more quickly. One set of devices is suitable for oil tanks of various depths, avoiding the cost of equipping specific detection equipment for different oil tanks, and realizing optimal utilization of resources. Even if the oil level in the tank is not full, effective detection can be carried out, avoiding misjudgment caused by oil level problems and ensuring the accuracy of the test results.
