ISO9001 Current Limiting Reactors Oil Immersed Type Reactor Are Used For Voltage

Fully Sealed Oil-Immersed Reactor,Current Limiting Reactors

1. Overview of Fully Sealed Oil-Immersed Reactor,Current Limiting Reactors

After the body is vacuum-dried, it is adjusted, and then it is installed in the oil tank and filled with transformer oil that has passed the purification treatment. Reactors with voltage levels of 35kV and above should be vacuum dried and then immersed in oil. In addition to the body and the fuel tank, the main components of this type of reactor include outlet bushings, radiators, oil storage tanks or metal expanders. The radiator compensates.

 2. Purpose of Fully Sealed Oil-Immersed Reactor,Current Limiting Reactors

The connection of the reactor is divided into two ways: series connection and parallel connection.
(1) Epoxy cast dry iron core shunt reactor: used to compensate the capacitive charging current of the line, limit the rise of the system power frequency voltage and operating overvoltage, thereby reducing the insulation level of the system and ensuring the reliable operation of the line. With the continuous expansion of the scale of my country’s cities and the transformation of urban power grids, overhead line transmission is gradually being replaced by underground cables, which makes the capacitive charging current of the transmission network increase sharply. In order to reduce the increase in the power frequency voltage of the system and the system The insulation level ensures the safe and reliable operation of the system and the quality of the power supply of the urban power grid. The shunt reactor, which was widely used in high-voltage and ultra-high-voltage, long-distance power transmission systems, has been widely used in urban power distribution grids.
(2) Epoxy cast dry iron core series reactor, installed in the capacitor circuit, plays the role of suppressing the inrush current when the capacitor circuit is put into operation, and also forms a harmonic circuit together with the capacitor bank for specific harmonic filtering In addition to the role.
