Problems solved by technology

Whether the oil level of the transformer oil conservator is normal or not is related to the safe operation of the transformer. There are two types of oil level gauges for large transformers. The first is the pressure type, which uses the pressure sensor at the bottom of the oil conservator to measure the height of the insulating oil level in the oil conservator; if the two measurement methods run for too long, the measurement will be inaccurate, and maintenance personnel still need to regularly check the real oil level of the oil conservator; At present, the most commonly used method by maintenance personnel is through the connecting pipe, but this method requires operators to climb to the transformer oil conservator for measurement, and the operation is highly dangerous.

Embodiment 1

[0028] Such as figure 1 As shown, a transformer oil conservator oil level detection device includes: a bracket, an adjustment plate 1, a laser ruler 2, and a pressure gauge 3; an adjustment plate 1 is set on the bracket, and the adjustment plate 1 is slidingly connected with the bracket; The ruler 2 is arranged on one side of the top of the adjustment plate 1, and the laser ruler 2 is connected with the adjustment plate 1; the pressure gauge 3 is arranged on the other side of the top of the adjustment plate 1, and the pressure gauge 3 is connected with the adjustment plate 1, The pressure gauge 3 is connected to the oil conservator of the transformer to be tested through a hose, and the laser ruler is used in conjunction with the pressure gauge to obtain the pressure of the pressure gauge at different positions from the oil conservator of the transformer to be tested, which can be directly measured and obtained through different pressures and distances The liquid level of the ...

Embodiment 2

[0030] A detection method of a transformer oil conservator oil level detection device, comprising the following steps:

[0031] S1. Place the bracket under the oil conservator under test, and adjust the height of each adjustment foot 61 according to the level bubble 62, so that the base 41 is level;

[0032] S2. Turn on the laser ruler 2 and adjust the position of the bracket so that the indication point of the laser ruler 2 is at the lowest point of the oil conservator;

[0033] S3. Connect the end of the hose far away from the quick connector 72 to the valve of the oil conservator to be tested. After opening the valve on the oil conservator, open the valve 73 on the tee 71. After the oil flowing out of the valve 73 is stable and free of air bubbles, Close valve 73 and the valve of the oil conservator under test;

[0034] S4. Disconnect the hose from the valve of the oil conservator under test, hold the end of the hose far away from the quick connector 72 above the pressure ...

Embodiment 3

[0040] In order to further improve the accuracy of detection, the quick connectors, pressure gauges and valves connected through the three-way connection can not only quickly connect the hose, but also discharge the gas inside the hose to prevent the gas from affecting the measurement results.

[0041] Such as image 3 , 4 As shown, preferably, a tee 71 is fixed on the top of the side of the adjustment plate 1 close to the pressure gauge 3, the pressure gauge 3 is located directly above the tee 71 and communicates with it, and the adjustment plate 1 is located directly below the tee 71 and also A quick joint 72 is provided, and one end of the quick joint 72 passes through the adjustment plate 1 to communicate with the tee 71, and the other end of the quick joint 72 is detachably connected with the hose. The outside of the adjustment plate 1 is also provided with a valve 73, which is connected to the three Through 71 communication, the quick connectors, pressure gauges and valve...

Abstract

The invention relates to a device and method for detecting the oil level of an oil conservator of a transformer, and belongs to the technical field of transformer detection equipment. The device comprises a support; an adjusting plate which sleeves the support and is connected with the support in a sliding manner; a laser ruler which is arranged at one side of the top of the adjusting plate, and connected with the adjusting plate; and a pressure gauge which is arranged at the other side of the top of the adjusting plate, connected with the adjusting plate and communicated with the transformer expansion tank to be tested through a hose; through cooperative use of the laser ruler and the pressure gauge, the pressure of the pressure gauge at different positions away from the to-be-detected transformer expansion tank can be obtained, the liquid level height of the to-be-detected transformer expansion tank can be directly measured and calculated through different pressures and distances, the oil level detection is accurate, the oil level of the to-be-detected oil conservator of transformer can be rapidly detected in a more convenient way, and detection device and method are easy to operate, high in accuracy, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of transformer detection equipment, and in particular relates to a transformer oil conservator oil level detection device and a method thereof. Background technique [0002] The oil level of the transformer oil conservator is an important monitoring parameter of the power transformer and an important guarantee for the normal operation of the transformer. Whether the oil level of the transformer oil conservator is normal or not is related to the safe operation of the transformer. There are two types of oil level gauges for large transformers. The first is the pressure type, which uses the pressure sensor at the bottom of the oil conservator to measure the height of the insulating oil level in the oil conservator; if the two measurement methods run for too long, the measurement will be inaccurate, and maintenance personnel still need to regularly check the real oil level of the oil conservator; At present, th...
