Description

Technical Field

[0001] The invention relates to the technical field of reactors, and in particular to a glass fiber yarn-free dry-type hollow reactor. Background Art

[0002] Reactors, also called inductors, are used by power systems as high-voltage electrical appliances for limiting short-circuit current, stabilizing voltage, reactive power compensation, and phase shifting because of their inductance. Reactors are classified into hollow, iron core, dry, and oil-immersed types according to their structure and cooling medium. They can also be divided into inductive and capacitive reactors. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight conductor with electricity is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid form, called a hollow reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called an iron core reactor.

[0003] Traditional dry-type hollow-core reactors use impregnated glass fiber to wrap the insulating conductor. The glass fiber needs to be pre-impregnated with glue during winding, which wastes a lot of time. In addition, the glass fiber is wrapped around the outside of the conductor, which seriously affects the heat dissipation of the conductor. In addition, existing reactors need to be used in groups when used. When the reactors are stacked vertically, there is a risk of them falling off due to the lack of a fixed position.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A card slot 108 is provided inside the fixing block 107, and the card slot 108 is clamped on the second bracket 105. A pair of arm plates 109 are fixedly installed on both sides of the buckle 106, and a support block 110 is fixedly connected between the other ends of the pair of arm plates 109, and a tray 112 is fixedly installed on the support block 110; it also includes a fastening component, a docking component and an adjustment component. The fastening component is arranged on the buckle 106 for fixing, the docking component is arranged on the arm plate 109 for matching use, and the adjustment component is arranged on the positioning plate 5 for matching use.

[0037] Specifically, it should be noted that the conventional reactor body 1 is wound with impregnated glass fiber to wrap the insulating layer conductor. The pre-impregnation of the glass fiber is required during the winding, which wastes a lot of time. In addition, the glass fiber is wrapped on the outside of the conductor, which seriously affects the heat dissipation of the conductor. As a result, the conventional dry-type hollow reactor is wound with impregnated glass fiber, and is easily exposed to moisture during processing for a long time in the air, which leads to burnout during use, poor heat dissipation, and high internal operating temperature, which will cause internal winding inter-turn discharge and burnout. The impregnated glass fiber accounts for more than 25%. The surface of the reactor body 1 of the present application is not provided with glass fiber yarn, and the outer side of the reactor body is wrapped with synthetic fiber materials, such as aramid (Kevlar), polyimide (such as Nomex) and other high-performance synthetic fibers. These materials have excellent mechanical strength and heat resistance, and good wear resistance and flexibility.

[0038] Thermosetting plastics: such as epoxy resin, phenolic resin, etc., which can be made into soft or rigid coatings with good insulation properties and chemical stability;

[0039] Ceramic materials: Ceramic coatings or fibers, such as alumina fibers, have high heat resistance and chemical stability, as well as good insulation properties;

[0040] Nanomaterials: such as nano-silicon oxide, nano-carbon tubes, etc. These materials can improve the mechanical properties and thermal stability of composite materials due to their unique physical and chemical properties;

[0041] Glass wool: Glass wool is a fluffy glass fiber material with good heat insulation and sound absorption properties. It can also be used as a surface coating material for the reactor. In this way, the processing time of the reactor body 1 is reduced and the overall heat dissipation effect of the reactor body 1 is increased. The specific working principles of the reactor body 1 are referenced through the existing technology and will not be elaborated here.
