Air core reactors are classified into series reactors, current limiting reactors, shunt reactors, filter reactors and smoothing reactors according to their applications. It is used in DC transmission systems of 110kV and below or DC transmission below ±800kV. Compared with iron core reactors, it has higher weather resistance, can be used outdoors, and has stable volt-ampere characteristics.

Features:

★ Product noise is small

When the dry type air core reactor is wound, the unique wire is used in the online glue-passing process, the wires are well bonded, and the reactor coil is solidified at a high temperature to be a solid whole. The vibration between the conductors does not occur inside the coil during operation. . The noise is significantly smaller than that of the same type of reactor.

★ low loss

Due to the optimized design of the computer and the real-time monitoring during winding, the produced reactor has excellent electrical parameters, and the noise is small during operation, which reduces the additional loss and reduces the loss of the same type of reactor by 10%. about.

★ Strong resistance to high current surge

When the reactor is running, it often encounters a short circuit. The reactor itself acts to limit the short-circuit current and itself is subject to a large short-circuit current. Produces great destructive power. The reactor encapsulating resin is enhanced by the use of glass filaments, and the short-circuit resistance is outstanding. Compared with other kinds of materials as follows:

★ Responsive linearity is good

Compared with the iron core reactor, since air is used as the main magnetic circuit, magnetic saturation phenomenon does not occur, and thus the reactance value of the air core reactor does not change with the current passing through the reactor, and the reactance linearity is very good.
