The mechanical floating ball type liquid level detection device also has certain requirements for the shape of the capsule oil tank, otherwise it cannot be installed. The mechanical floating ball type liquid level detection device is easy to form false oil level due to jamming. Invention content

[0030] EMBODIMENT

[0031] Please refer to Figs. 1-2 The utility model provides the following technical scheme: a transformer oil storage shelter, including detection control unit 13, oil filter unit 14 and oil chromatographic detection unit 15, still including,

[0032] Oil tank a 1 and oil tank b 2, the outer oil capsule 3 is arranged in it, and the bottom of oil tank a 1 and oil tank b 2 is communicated with oil tank oil outlet pipe 10 and oil tank oil inlet pipe 9;

[0033] Electronic oil level gauge 6 is installed at the upper and lower ends outside oil tank a 1 and oil tank b 2;

[0034] Detection control unit 13, the oil filter unit 14 is electrically connected with detection control unit 13 through oil filter unit and detection control unit data line 23, and detection control unit 13 is electrically connected with two electronic oil level gauges 6 through electronic oil level gauge and detection control unit serial data line 24 respectively;

[0035] Breather, the upper side is communicated with outer oil capsule 3 through capsule exhaust pipe 4;

[0036] The oil chromatography detection unit 15 is connected to the detection control unit 13 via the data line 22 of the oil chromatography detection unit and the detection control unit. The lower side of the oil chromatography detection unit 15 is connected to the first oil inlet pipe 25 and the first oil outlet pipe 26 respectively. The bottom ends of the first oil inlet pipe 25 and the first oil outlet pipe 26 are connected to the oil filter unit inlet pipe 16 and the oil filter unit outlet pipe 17.

[0037] The oil filter unit 14 has an oil filter unit inlet pipe 16 and an oil filter unit outlet pipe 17 connected to its lower side.

[0038] Specifically, a lower oil level gauge pressure transmitter 8 is installed at the lower end of the electronic oil level gauge 6, and an upper oil level gauge pressure transmitter 7 is installed on the upper side of the external oil capsule 3.

[0039] To ensure that the oil does not get damp during long-term storage, there is an external oil capsule 3 inside the capsule oil tank. The pressure difference between the liquid level and the upper space of the capsule is large, so the position of the oil level inside the capsule oil tank cannot be accurately displayed by means of a communicating vessel alone.

[0040] The oil level inside the tank is calculated by detecting the pressure of the liquid level in the oil level gauge and the upper space of the capsule, as well as the pressure of the oil surface at the bottom of the electronic level gauge, combined with the oil temperature.

[0041] Specifically, a first oil outlet solenoid valve 11 and a first oil inlet solenoid valve 12 are respectively installed on the outer surfaces of the oil tank outlet pipe 10 and the oil tank inlet pipe 9.

[0042] Each oil storage unit can be connected in parallel to the oil inlet pipe 16 and the oil outlet pipe 17 of the oil filter unit, and different numbers of oil storage tanks can be connected in parallel as needed;

[0043] Initially, only one oil storage tank can be used, and additional oil storage tanks can be added later. The additional oil storage tanks integrate the oil tank, breather, inlet and outlet solenoid valves, electronic oil level gauge, etc. into a sealed container that can be connected via flanges.

[0044] Specifically, an oil chromatography detection unit inlet solenoid valve 20 and an oil chromatography detection unit outlet solenoid valve 21 are respectively installed on the outer surfaces of the first oil inlet pipe 25 and the first oil outlet pipe 26.

[0046] The detection and control unit 13 can cyclically connect each oil storage unit to the system according to the set operating mode, and perform oil chromatography detection and oil filtration treatment such as vacuum degassing, dehydration and impurity removal. It can detect the oil weight, oil chromatography detection data and trace water detection data of different oil tanks respectively, and save the data separately.

[0047] When oil extraction is required, the oil extraction operation can be selectively performed. Oil tank A1 has better oil quality, and the system can determine which oil tank to use for oil output based on the data quality and the amount of oil stored.

[0048] The system automatically filters oil from different tanks, monitors oil weight, and measures oil chromatogram and trace moisture levels. Simultaneously, it prioritizes processing oil from different tanks based on their data, ensuring that the oil in each tank remains in excellent condition.

[0049] The quality of the oil inside the tank is calculated based on its internal shape and oil level.

[0050] Working principle and usage process of this utility model:

[0051] In use, this utility model is as follows:

[0052] As shown in the diagram, the system comprises an oil filtration unit 14, a detection and control unit 13, an oil chromatography detection unit 15, and an oil storage unit. The oil storage unit includes an oil tank containing an external oil capsule 3, a capsule breather 5, and an electronic oil level gauge 6. Each oil storage unit can be connected in parallel to the oil inlet pipe 16 and the oil outlet pipe 17 of the oil filtration unit. Different numbers of oil tanks can be connected in parallel as needed. Initially, only one oil tank can be used, with additional tanks added later. These additional tanks integrate the oil tank, breather, inlet / outlet solenoid valves, and electronic oil level gauge 6 into a sealed container that can be connected via flanges. The oil level gauge calculates the oil tank pressure by detecting the oil level, the pressure above the capsule, and the pressure below the electronic level gauge, combined with the oil temperature. The internal oil level detection and control unit 13 can cyclically connect each oil storage unit to the system according to the set operating mode, performing oil chromatography detection and filtration processes such as vacuum degassing, dehydration, and impurity removal. It can separately detect the oil weight, oil chromatography data, and trace moisture detection data from different oil tanks, and save the data separately. When oil extraction is required, it can selectively extract oil; oil tank a1 has better oil quality, and the system can determine which tank's oil to use for output based on data quality and stored oil volume. Normally, the system automatically filters the oil from different tanks, detecting their oil weight, oil chromatography data, and trace moisture detection data, while simultaneously prioritizing the oil from the tank based on its data. Ultimately, this ensures that the oil in each tank is always in excellent condition.

[0053] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
