Novel high-impedance electric reactor

Abstract

The invention discloses a novel high-impedance electric reactor in the technical field of electric reactors, which comprises a winding cylinder and a winding, the winding is wound on the outer surface of the winding cylinder, and the inner side of the winding cylinder is provided with a plurality of vent grooves in a circumferential distribution array; when the high-load working temperature of the electric reactor is sharply increased every time, a sealing mechanism and the winding cylinder are utilized to form the sealed space, the winding wound on the outer side of the winding cylinder is completely surrounded, cooling oil is stably and rapidly squeezed into the sealed space through an oil immersion mechanism, winding immersion is slowly reduced, the oil liquid rapidly dissipates the heat of the winding, the winding is cooled, the winding is prevented from being damaged in a high-temperature state, after the action is completed, the sealing mechanism is opened again, the oil immersion mechanism is reset, the oil liquid falls back again, and finally the winding is exposed in the air, so that the winding can be subjected to good air cooling heat dissipation during normal work, and the stable work of the electric reactor is facilitated.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a novel high-impedance reactor. Background technique [0002] Reactors are also called inductors, which provide inductance values ​​on the circuit, play a role in limiting short-circuit current and providing inductive reactive power on different occasions, and are divided into iron-core reactors and air-core reactors in structure. The magnetic circuit of the air-core reactor is air, there is no saturation phenomenon, and the reactance value is fixed, so it is widely used in the power system. [0003] The reactor in the prior art will generate heat due to the thermal effect of the current when it is used. If it is not dissipated in time, it will cause the insulation of the conductor to age. Moreover, the cooling of the existing reactor is relatively slow, and the reactor cannot be cooled in time. [0004] Based on this, the present invention designs a novel high-impedance react...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a novel high-impedance reactor to solve the above-mentioned background technology. The reactor in the prior art will generate heat due to the thermal effect of the current when it is used. If it is not dissipated in time, it will lead to conductor damage. Insulation aging, in severe cases, insulation damage forms inter-turn short circuit, which leads to the burning of the entire reactor, and the cooling of the existing reactor is relatively slow, and the reactor cannot be cooled in time
