Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer voltage stabilizing structure. Background Art

[0002] A transformer is an electrical device used for electric energy conversion. It can convert AC power of one voltage and current into AC power of another voltage and current of the same frequency. Currently, when the transformer is in use, if the transformer fails or has an abnormal condition, such as winding short circuit or bushing damage, it may cause voltage transmission between the high and low voltage bushings.

[0003] At present, there is no structure for voltage stabilization protection between the high-voltage bushing and the low-voltage bushing in the existing transformer, which makes it impossible for personnel to take corresponding protective measures to prevent damage to equipment or personnel, resulting in poor practicality. Therefore, a transformer voltage stabilization structure is proposed to facilitate voltage stabilization protection of the transformer, thereby improving safety. Utility Model Content

The hard cable bushing is sleeved on the periphery of the soft cable bushing, the inside of the soft cable bushing is inlaid with a cable, and the voltmeter is installed on the hard cable bushing by a mounting plate and screws.

[0011] Specifically, a transformer oil pillow is provided on the top of the transformer body between the high-voltage bushing and the low-voltage bushing.

[0013] By adopting the above technical solution, this method can effectively ensure the stability of the transformer oil pillow.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] In order to stabilize the voltage of the transformer and improve safety, Figure 1-4 As shown, a transformer voltage stabilizing structure comprises a transformer body 1, a high voltage bushing 2 and a low voltage bushing 3 are respectively arranged on both sides of the top of the transformer body 1, and a voltage stabilizing component is arranged between the high voltage bushing 2 and the low voltage bushing 3;

[0029] The voltage stabilizing component includes a hard cable bushing 801, a soft cable bushing 802 and a voltmeter 803. The hard cable bushing 801 is sleeved on the outer periphery of the soft cable bushing 802. The inside of the soft cable bushing 802 is embedded with a cable 9. The voltmeter 803 is installed on the hard cable bushing 801 by means of a mounting plate 10 and screws.

[0030] When in use, the voltmeter 803 is an instrument for measuring voltage. The structure of the voltmeter is as follows: a permanent magnet is inside a sensitive galvanometer, a coil consisting of a wire is connected in series between two terminals of the galvanometer, the coil is placed in the magnetic field of the permanent magnet, and is connected to the pointer of the meter through a transmission device;

[0031] The voltmeter 803 can detect the voltage between the high-voltage bushing 2 and the low-voltage bushing 3 in real time, so that personnel can take corresponding emergency protection measures in real time to prevent damage to equipment or personnel. The purpose of voltage stabilization can be indirectly achieved by detecting the voltage, thereby improving safety.

[0032] The U-shaped base 6 can limit the transformer body 1 at the periphery of the transformer body 1, and the spring 7 can buffer and dissipate energy when the transformer body 1 is hit by foreign objects, thereby preventing the transformer body 1 from being damaged due to the impact force.

[0033] In order to stabilize the voltage of the transformer and improve safety, for example, Figure 1 , Figure 2 As shown, a U-shaped base 6 is provided on the outer side of the transformer body 1 , and springs 7 are evenly provided between the U-shaped base 6 and the transformer body 1 .

[0034] When in use, the U-shaped base 6 can limit the transformer body 1 at the periphery of the transformer body 1 , and the spring 7 can buffer and dissipate energy when the transformer body 1 is hit by foreign objects.

[0035] For example, Figure 1 As shown, a transformer oil pillow 4 is provided at the top of the transformer body 1 between the high-voltage bushing 2 and the low-voltage bushing 3 .

[0036] When in use, the transformer oil contacts the air only in the transformer oil pillow 4 through the transformer oil pillow 4, and the contact surface with the air is reduced to avoid moisture and oxidation. The moisture absorbed by the transformer oil from the air will be deposited in the dirt collector at the bottom of the transformer oil pillow 4 so as to be discharged regularly. Therefore, the transformer oil pillow 4 plays an important role in ensuring the safe operation of the transformer and extending its service life.

[0037] For example, Figure 1 As shown, the bottom of the transformer oil pillow 4 is connected to the transformer body 1 through a mounting seat 5 .

[0038] When in use, this method can effectively ensure the stability of the transformer oil pillow 4.

[0039] For example, Figure 1 , Figure 3 As shown, the hard cable sleeve 801 is made of ceramic material.

[0040] When in use, the hard cable sleeve 801 made of ceramic material has the advantages of high mechanical strength, corrosion resistance, good fire resistance, etc., has a long service life, and is convenient for the installation of the voltmeter 803.

[0041] For example, Figure 1 , Figure 3 As shown, the soft cable sleeve 802 is made of PVC material.

[0042] When in use, the soft cable sleeve 802 made of PVC material is not only light in weight and easy to install, but also low in cost and good in practicality.

[0043] When the utility model is in use, under normal working conditions, no direct voltage transmission occurs between the high-voltage bushing 2 and the low-voltage bushing 3. However, when the insulation performance of the high-voltage bushing 2 and the low-voltage bushing 3 decreases, is damaged or aged, or due to operating errors, lightning, electromagnetic pulse interference, etc., the possibility of voltage transmission is likely to increase, which will not only cause equipment damage, but also cause safety accidents such as fire, and even cause personal injury.

[0044] When the transformer has a fault or abnormal situation such as winding short circuit or bushing damage, the voltmeter 803 detects the voltage generation, and the personnel can take corresponding emergency protection measures in real time to prevent damage to equipment or personnel. The purpose of voltage stabilization is indirectly achieved by detecting the voltage, thereby improving safety.

[0045] Through the U-shaped base 6 and the spring 7, the U-shaped base 6 can limit the transformer body 1 at the periphery of the transformer body 1, and the spring 7 can play a role of buffering and energy dissipation when the transformer body 1 is hit by an external object, thereby preventing the transformer body 1 from being damaged due to the impact force, thereby ensuring the stability of the transformer body 1 and preventing the transformer body 1 from shaking during operation.

[0046] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
