35kv 3-phase dry type hollow current-limiting reactor

Abstract

The invention relates to a kind of 35 kv three phase dry-type hollow limiting reactor that comprises loop, insulation canister, upper and lower splint, it characterized in that the loop of reactor adopts copper twisted line which includes multiple thin copper lines to enwind on the insulation canister, the outer of the copper twisted line is insulation layer, surface of every layer is epoxide resin solidify; F class insulation cold drawing duct bar is set between every layer of loop, end insulation is set at the upper and lower end, the thickness of the end insulation is the same with the diameter of lead; it through the duct bar and end insulation, and rivets the duct bar to the end insulation and splint via insulation bar. It possesses advantages that the structure is simple and reasonable, property of anti short-circuit current is strong, the electric property is good, the volume is small, weight is light, the noise is low.

Description

technical field [0001] The invention relates to a dry-type hollow current-limiting reactor. Background technique [0002] The dry-type air-core current-limiting reactor has only coils and no iron core. The magnetic circuit is a non-magnetic material with a large reluctance and a small inductance value. There is no saturation phenomenon. The inductance value is a constant. Due to the good electrical It is widely used in various fields of electric power engineering and modern electric engineering, and is an indispensable and important equipment for electrical engineering. [0003] There are three types of traditional dry-type air-core current-limiting reactors. One is to use concrete to pour the wound reactor coil into a solid whole called a cement reactor. This cement current-limiting reactor is large in size, heavy in weight, and too cumbersome. Second, it is called a wrapping reactor wound with variable wire diameter (small wire diameter) al...

AI Technical Summary

Problems solved by technology

One is to use concrete to pour the wound reactor coil into a solid whole called a cement reactor. This cement current-limiting reactor is large in size, heavy in weight, and too cumbersome.

Second, it is called a wrapping reactor wound with variable wire diameter (small wire diameter) aluminum wire. The aluminum wire of this current-limiting reactor is easy to oxidize, has poor mechanical strength and low service life.

Third, use a pressure plate and a pull rod to tighten the wound reactor coil, which is called a clamping reactor. This kind of current-limiting reactor has poor moisture-proof performance and large additional losses.

The above three reactors cannot achieve the best results in the operation of the power system
