Description

Technical Field

[0001] This utility model relates to the field of transformer breather technology, specifically to a U-shaped interconnected transformer breather. Background Technology

[0002] A transformer breather, also known as a desiccant, is a glass container filled with desiccant materials such as color-changing silica gel. Its function is to absorb moisture from the air that enters the oil conservator bladder and diaphragm, removing and drying impurities and moisture from the air that enters the oil conservator bladder due to changes in transformer oil temperature. This prevents the transformer from becoming damp and ensures the insulation strength of the transformer oil. When the transformer expands due to heat, it expels excess air from the oil conservator bladder; when the transformer oil contracts due to a decrease in temperature, it draws in outside air. When outside air is drawn in, the transformer oil in the oil reservoir (oil cup) filters the outside air, and then the silica gel absorbs any unfiltered moisture, preventing the transformer oil from being invaded by moisture from the outside air and keeping its moisture content within the standard range. When the color-changing silica gel changes from blue to pink, it indicates that the absorbent has become damp and must be replaced and dried.

[0003] In the current technology, the silicone replacement of the transformer breather is carried out by removing the breather. However, this leaves the interface between the breather and the oil tank directly exposed to the air, which can easily allow air to enter the oil tank. Furthermore, the lack of a heating device leads to problems such as unsafe and inconvenient use. Utility Model Content

[0004] The purpose of this invention is to provide a U-shaped interconnected transformer breather to solve the problems mentioned in the background art.

The surface of the three-way pipe is provided with a connecting mechanism, the surface of the connecting mechanism is provided with an auxiliary mechanism, and the surface of the connecting mechanism is provided with a heating mechanism.

[0007] The connecting mechanism includes a first threaded mounting plate, a second threaded mounting plate, a threaded post, a nut, and a first rubber pad. There are two of each of the first threaded mounting plate, the first rubber pad, and the second threaded mounting plate. The upper surface of the first threaded mounting plate is fixedly connected to the surface of the tee pipe.

[0008] A further improvement of this utility model is that: the surface of the second threaded mounting plate is fixedly connected to the surface of the first butterfly valve, the lower surface of the first butterfly valve is movably connected to the surface of the first breather, the lower surface of the first threaded mounting plate is fixedly connected to the surface of the first rubber pad, and the lower surface of the first threaded mounting plate is movably connected to the upper surface of the second threaded mounting plate.

[0010] A further improvement of this utility model is that the surface of the nut is threadedly connected to the surface of the threaded post, and the surface of the nut is movably connected to the lower surface of the second threaded mounting plate.

[0011] A further improvement of the present invention is that the auxiliary mechanism includes a second rubber pad and a second respirator. There are two second rubber pads.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a U-shaped interconnected transformer breather, which employs a first breather, a second butterfly valve, a connecting mechanism, and an auxiliary mechanism. Utilizing the cooperation between the second butterfly valve, the first butterfly valve, the first threaded mounting plate, the second threaded mounting plate, the threaded column, the nut, the first rubber gasket, the first breather, the second rubber gasket, and the second breather, when the silica gel in the first breather becomes damp and needs replacement, the spare second breather is installed on the right-side first threaded mounting plate via the second threaded mounting plate, the threaded column, and the nut. The second butterfly valve is then opened to put the second breather into operation. Subsequently, the first butterfly valve is closed, and the first breather is safely removed for silica gel replacement. This allows for safe silica gel replacement without power interruption, ensuring a continuous and stable transformer breathing process. The sealing of the first and second rubber gaskets ensures tight connection and moisture resistance, preventing air leakage and moisture intrusion, thus facilitating use.

[0016] 2. This utility model provides a U-shaped interconnected transformer breather, which adopts a first breather and a heating mechanism. It utilizes the cooperation between the first breather, the heat-conducting ring block, the heating wire, and the rubber ring. By using the elasticity of the rubber ring, the heat-conducting ring block is fitted onto the surface of the first breather. The heating wire is used for heating, and the heat-conducting ring block conducts heat to transfer heat to the first breather. This can prevent the moisture inside the breather from freezing, avoid pipe blockage or damage to the desiccant caused by freezing, and ensure that the breather can work normally in low-temperature environments, thus enhancing the practicality of the device.

The surfaces are fixedly connected, the lower surface of the first threaded mounting plate 31 is movably connected to the upper surface of the second threaded mounting plate 32, the surface of the threaded post 33 is threadedly connected to the threaded hole on the surface of the first threaded mounting plate 31, the surface of the threaded post 33 is threadedly connected to the threaded hole on the surface of the second threaded mounting plate 32, the surface of the nut 34 is threadedly connected to the surface of the threaded post 33, and the surface of the nut 34 is movably connected to the lower surface of the second threaded mounting plate 32.

The surface of the second rubber pad 41 is fixedly connected to the surface of the second threaded mounting plate 32, the upper surface of the second rubber pad 41 is movably connected to the lower surface of the first rubber pad 35, the surface of the second butterfly valve 8 is fixedly connected to the surface of the second threaded mounting plate 32, and the surface of the second butterfly valve 8 is fixedly connected to the surface of the second respirator 42.

[0026] In this embodiment, both the first breather 9 and the second breather 42 are transparent devices.

The second butterfly valve 8 is opened to put the second breather 42 into operation.
