Problems solved by technology
[0003] The existing voltage transformers are prone to ferromagnetic resonance during use. Ferromagnetic resonance is a form of self-excited oscillation in power systems, which is caused by the saturation of ferromagnetic inductance in transformers and voltage transformers. Amplitude resonance overvoltage phenomenon, ferromagnetic resonance will cause serious damage to equipment, so developing a protective structure that can demagnetize is a technical problem that needs to be solved by those skilled in the art

The invention discloses a demagnetization protection structure of a voltage transformer and relates to the technical field of voltage transformers. The invention includes a voltage transformer, the top of the voltage transformer is fixedly connected with two connection terminals, the bottom of the voltage transformer is fixedly connected with two C-shaped steels, and two connecting rods run through the inside of the C-shaped steels, and the two C-shaped steels pass through two connecting rods. A connecting rod is fixedly connected with another C-shaped steel, the top of the voltage transformer is fixedly connected with an angle iron, the bottom of the angle iron is fixedly connected with a drive motor, the top surface of the C-shaped steel on the left side of the voltage transformer is fixedly connected with an oil pump, and the voltage transformer The spiral tube is fixedly connected to the side of the device circumference. The invention rolls a plurality of magnetic balls along the spiral tube around the voltage transformer, and can evenly demagnetize the voltage transformer to avoid the occurrence of ferromagnetic resonance. The oil circuit prevents the accumulation of heat inside the voltage transformer and improves the stability of the voltage transformer.
Description
technical field [0001] The invention relates to the technical field of voltage transformers, in particular to a demagnetization protection structure for voltage transformers. Background technique [0002] A voltage transformer is similar to a transformer and is an instrument used to transform voltage. However, the purpose of transforming the voltage of the transformer is to facilitate the transmission of electric energy, so the capacity is very large, and it is generally calculated in kilovolt-ampere or megavolt-ampere; The power supply of the protection device is used to measure the voltage, power and electric energy of the line, or to protect the valuable equipment, motor and transformer in the line when the line fails. Therefore, the capacity of the voltage transformer is very small, generally only a few volts, Dozens of VA, the maximum is no more than 1000 VA. [0003] The existing voltage transformers are prone to ferromagnetic resonance during use. Ferromagnetic reso...
