Performance characteristics of JSXN-35 and JSXNF-35 three-phase oil immersed voltage transformers

The JSXN-35 and JSXNF-35 three-phase oil immersed voltage transformers have reformed the magnetic circuit structure of the original three-phase five column voltage transformer based on the mechanism of three-phase ferromagnetic resonance. They adopt a combination of three-phase three column magnetic circuit and single port magnetic circuit, and the positive sequence voltage and zero sequence voltage under ferromagnetic resonance are respectively borne by the above magnetic circuits. This is the key to improving the zero sequence excitation characteristics, anti resonance and anti burning. Therefore, it is not allowed for any side of the zero sequence winding to be short circuited.
The JSZG (F) -35 product is a new generation of poured indoor product designed based on user requirements, which is a completely new version of the original JSXN-35 oil immersed indoor product. This product has a reasonable structure, a large surface creepage distance, superior performance, small and short size, and is particularly suitable for the installation of switchgear.
3 can effectively eliminate frequency division, power frequency, and high-frequency resonance, without overvoltage burning, and without frequent melting of high-voltage insurance.
When the system is single-phase grounded, the output voltage of the remaining winding dadn of the product is 100V.
When the system is running normally, the remaining winding output voltage is less than 1V.
When one phase of the high-voltage fuse is blown, the output voltage of the remaining winding is about 50V, which can make the grounding monitoring relay reliably alarm. This method can be used to check whether the secondary winding is short circuited due to multiple grounding points.
Provide accurate line voltage for meter measurement, provide accurate phase voltage for reflecting the system to ground.
The 8 F type has two measurement stage windings and one residual voltage winding, which greatly facilitates users.
