Description

Technical Field

[0001] The utility model relates to the field of lead wire installation of oil-immersed transformers, in particular to a lead wire structure of a three-voltage level new energy wind power transformer. Background Art

[0002] The three-voltage level new energy wind power transformer mainly adopts oil-immersed transformer. However, in general, the leads of the three-voltage level new energy wind power transformer are connected to the two ends of the high-voltage bushing of the oil-immersed transformer.

[0003] The lead wires at the top of the existing three-voltage level new energy wind power transformer bushing are generally connected to other wires or equipment. However, since the oil-immersed transformer is installed at high altitude, and the installation method of this section of the lead wire is to connect the sleeve head with the installation head, and then press and fix it with fixing bolts, the lead wire will shake during long-term use, which may pose a hidden danger. For example, the shaking of the lead wire may cause the electrical connection to gradually loosen, which will affect the stable transmission of current. The loose connection may increase the contact resistance and produce irregular resistance changes, which will not only cause three-phase imbalance, but also may generate high-frequency or distorted current, which will have an adverse effect on the waveform and phase of the output voltage. Moreover, when the electrical connection is unstable, intermittent contact may cause an arc, that is, partial discharge. This partial discharge will damage the lead wire and may even produce gas in the transformer oil, reducing the quality of the oil, thereby affecting the overall performance and life of the transformer. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a three-voltage level new energy wind power transformer lead structure to solve the technical problems of loose electrical connection, resistance change, three-phase imbalance, high-frequency or distorted current, arc generation and transformer oil quality degradation caused by lead shaking.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-voltage level new energy wind power transformer lead structure, including a high-voltage porcelain column and a lead, the outer side of the high-voltage porcelain column is sleeved with a stabilizing mechanism, the stabilizing mechanism includes a first embrace ring and a second embrace ring, the inner sides of the first embrace ring and the second embrace ring are both provided with two mounting ears, the two mounting ears are threadedly connected with mounting bolts, the first embrace ring and the second embrace ring are fixedly connected by the mounting bolts, and the first embrace ring and the second embrace ring are sleeved with the high-voltage porcelain column;

[0006] Side blocks are arranged on both sides of the first holding ring and the second holding ring, and a rotating rod is rotatably connected to the two side blocks. A mounting groove is arranged at the front end of the rotating rod, and the stabilizing mechanism is used to limit the lead wire.

[0007] By adopting the above technical solution, the high-voltage porcelain column is used as a support and insulation structure to ensure electrical safety, and the lead wire is used as a key part of current transmission to ensure the effective transfer of electrical energy.

[0008] Furthermore, the material of the stabilizing mechanism is aluminum alloy, and the material of the outer surface of the lead is rubber.

[0009] By adopting the above technical solution, the stabilizing mechanism made of aluminum alloy is both light and corrosion-resistant, and can effectively support and protect the high-voltage porcelain column; the outer surface of the lead made of rubber provides good insulation and flexibility, enhancing safety of use.

[0010] Furthermore, a protective mechanism is provided on the outer surface of the lead wire, and the protective mechanism includes a casing, and the casing is sleeved with the lead wire.

[0011] By adopting the above technical solution, the protective mechanism and the casing provide an additional protective layer for the lead wire, preventing the lead wire from being damaged due to environmental factors such as moisture, dust, etc., thereby extending the service life of the lead wire.

[0012] Furthermore, a mounting ring is fixedly connected to the outer surface of the sleeve, and side ears are provided on both sides of the mounting ring. The two side ears are respectively inserted into the inside of the two mounting grooves, and the two side ears are fixedly connected to the two mounting grooves by disassembling bolts.

[0013] By adopting the above technical solution, this design enables the protection mechanism to be firmly connected to the stabilizing mechanism, thereby ensuring the stability and reliability of the entire lead structure.

[0014] Furthermore, the lead wire is arranged in a flexible structure, and the housing is made of stainless steel.

[0015] By adopting the above technical solution, the leads of the flexible structure are easy to install and wire, reducing the risk of breakage due to external force. The stainless steel shell is strong and durable, and can effectively resist erosion from the external environment.

[0016] Furthermore, a mounting head is provided on the top of the high-voltage porcelain column, and a sleeve is provided on one end of the lead wire, and the sleeve is sleeved with the mounting head.

[0017] By adopting the above technical solution, this design simplifies the connection process between the lead wire and the high-voltage porcelain column, making installation more convenient while ensuring the stability and safety of the electrical connection.

[0018] Furthermore, a fixing bolt is threadedly connected to the mounting head, and the fixing bolt is used to press and fix the mounting head.

[0019] By adopting the above technical solution, the fixing bolt provides a reliable fixing method for the mounting head, preventing the connection between the lead wire and the high-voltage porcelain column from loosening or disconnecting, thereby ensuring the stable operation of the electrical system.

[0020] Furthermore, wear-resistant rings are arranged on the inner sides of the first holding ring and the second holding ring, and the material of the wear-resistant rings is rubber.

[0021] By adopting the above technical solution, the provision of the wear-resistant ring reduces the friction loss between the holding ring and the high-pressure porcelain column, prolongs the service life, and also enhances the stability of the entire stabilizing mechanism. The rubber material of the wear-resistant ring also provides good buffering and shockproof effects.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. The utility model significantly enhances the stability of the entire transformer top structure by setting a stabilizing mechanism, wherein the first holding ring and the second holding ring are tightly sleeved on the high-voltage porcelain column by mounting bolts. This stability is crucial to reducing the shaking of the lead wire in long-term use, thereby ensuring the safety and reliability of the electrical connection. In addition, the mounting ring and side ears on the housing, as well as the mounting groove on the matching rotating rod, make the installation and removal of the protective mechanism simple and quick. This design not only facilitates daily maintenance and overhaul, but also improves work efficiency;

[0024] 2. The utility model provides an additional protective layer for the lead by setting a shell, which is tightly sleeved on the lead. This design can prevent the lead from being directly damaged in harsh environments, such as wind and rain erosion, ultraviolet radiation, etc., thereby extending the service life of the lead. The shell is made of stainless steel and has high mechanical strength. It can effectively resist external physical impact and reduce possible damage to the lead during transportation, installation and use. The mounting ring and side ear design on the outer surface of the shell make it easy to install the shell on the stabilizing mechanism, plug it into the inside of the mounting groove through the side ear, and use the disassembly bolts to fix the connection, thereby ensuring the stability between the shell and the stabilizing mechanism.
