Its core function is to increase or decrease voltage, and it can also perform current transformation, impedance transformation, isolation, and voltage stabilization.

[0003] After the existing transformers are put into use, the staff need to regularly inspect the oil-proof structure installed inside. Because the space for installing the oil-proof structure is relatively narrow and the internal installation structure is relatively complex, when the staff use external tools to disassemble and assemble the oil-proof structure, the narrow space can easily restrict the staff's movement and make it inconvenient for the staff to operate. Utility Model Content

[0004] The purpose of this utility model is to provide a transformer with an oil-proof structure to solve the problem mentioned in the background art that existing transformers require regular maintenance of the internal oil-proof structure after use.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] Please see Figure 1-5 As shown, this embodiment is a transformer with an oil-proof structure, including:

[0039] Main components: The main components include a power transformer 11, an oil leakage collection base 12, an oil filling port 13, and an oil leakage collection pipe 14;

[0040] The oil leakage collection base 12 is fixedly connected to the bottom end of the power transformer 11, the oil filling port 13 is installed at the top end of the power transformer 11, and the oil leakage collection pipe 14 is installed on the outside of the oil leakage collection base 12.

[0041] The main components also include an alarm 15, a filter 16, a through hole 17, and a sealing strip 18;

[0042] The alarm 15 is installed on the outside of the housing 21, the filter screen 16 is fixedly connected to the inside of the oil leakage collection seat 12, the through hole 17 is opened at the top of the oil leakage collection seat 12, and the sealing strip 18 is fixedly connected to the top of the oil leakage collection seat 12.

[0043] The alarm 15 provides an auxiliary alarm through a liquid level sensor installed in the oil leakage collection seat 12, which is used to collect leaked oil.

[0044] Oil seeping into the power transformer 11 is collected inside the oil collection base 12 through the through hole 17 and filtered through the filter screen 16. When the oil level in the oil collection base 12 is too high, the hydraulic alarm 15 is activated, and the oil collected inside the oil collection base 12 is returned to the power transformer 11 through the oil replenishment pump 24 and the bend pipe installed at its top.

[0045] The power transformer 11 is based on the electromagnetic induction phenomenon of "electricity generating magnetism, and magnetism generating electricity." When alternating current passes through the primary coil, an alternating magnetic field is generated in the iron core, which in turn induces an electromotive force in the secondary coil. By adjusting the turns ratio of the primary and secondary coils, voltage transformation can be achieved.

[0046] All of the above parts are existing technologies;

[0047] Maintenance components: The maintenance components include housing 21, connecting plate 22, retaining strip 23 and oil replenishment pump 24;

[0049] The maintenance components also include a retaining ring 25, a sealing cylinder 26, an oil pipe 27, a sealing ring 28, and a slot 29;

[0050] The retaining ring 25 is fixedly connected to both sides of the outer wall of the oil replenishing pump 24, the oil pipe 27 is fixedly connected to one end of the oil replenishing pump 24, the sealing cylinder 26 is fixedly connected to the outside of the oil pipe 27, the sealing ring 28 is fixedly connected to the inside of the oil leakage collection seat 12, and the slot 29 is opened on the inner side wall of the oil leakage collection seat 12.

[0051] The sealing ring 28 is used to provide space for the oil pipe 27 to be inserted. The sealing ring 28 and the sealing cylinder 26 are set on the same central axis. The slot 29 is used to provide space for the insertion pair of the retaining strip 23. The retaining ring 25 is used to provide space for the retaining strip 23 to pass through the limiting position.

[0052] With the auxiliary cooperation between the connecting plate 22 and the retaining strip 23, the oil pump 24 can be removed and inspected while the connecting plate 22 is pulled outward.

[0053] Working principle: When the staff is inspecting and repairing the oil replenishment pump 24;

[0054] First, by pulling the connecting plate 22 outward, the staff can slide the inner locking strip 23, releasing the engagement between the locking strip 23 and the slot 29, and pulling the locking strip 23 out of the inside of the locking ring 25, which can release the limitation on the oil pump 24, thus making it easier for the staff to take the oil pump 24.

[0055] Next, when installing and resetting the oil pump 24, the oil pipe 27 installed at one end of the oil pump 24 can be inserted into the inside of the oil leakage collection seat 12, and the sealing ring 28 and the sealing cylinder 26 can be engaged.

[0056] This step allows staff to easily disassemble and limit the oil pump 24 while providing them with ample maintenance space.

[0057] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, also includes an installation component;

[0058] The mounting components include a mounting cylinder 31, a threaded rod 32, a mounting plate 33, a circular frame 34, and a rotating frame 35;

[0059] The mounting cylinder 31 is fixedly connected to the outside of the oil leakage collection seat 12, the threaded rod 32 is rotatably connected to the inside of the mounting cylinder 31, the circular frame 34 is rotatably connected to the inside of the mounting cylinder 31, the mounting plate 33 is fixedly connected to the outside of the circular frame 34, and the rotating frame 35 is rotatably connected to the inside of the circular frame 34.

[0060] The mounting components also include a connecting pipe 36, a locking block 37, and a connecting block 38;

[0062] The threaded rod 32 and the mounting plate 33 are set on the same central axis. The rotating frame 35 is used to provide space for the locking block 37 to fit, and the circular frame 34 is used to provide space for the connecting block 38 to connect.

[0063] Through the threaded engagement between the threaded rod 32 and the mounting plate 33, the circular frame 34 can be rotated while the threaded rod 32 is rotated, and multiple sets of locking blocks 37 can be flipped.

[0064] Working principle: When the staff installs the oil leakage collection pipe 14;

[0065] First, one end of the oil leakage collection pipe 14 can be threaded to the connecting pipe 36. At the same time, by rotating the threaded rod 32 clockwise, the threaded rod 32 can drive the external mounting plate 33 to slide during the rotation, which can make the circular frame 34 rotate.

[0066] Next, the circular frame 34 can be rotated to drive the inner rotating frame 35 to rotate. The connecting block 38 installed at one end of the locking block 37 is connected to the circular frame 34. During the swing of the rotating frame 35, multiple sets of locking blocks 37 can be driven to rotate, and the external of the connection end of the oil leakage collection pipe 14 and the connecting pipe 36 can be auxiliaryly clamped.

[0067] This step can assist workers in installing the oil leakage collection pipe 14 while increasing the stability of the installation.
