Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a combined air-core reactor. Background Art

[0002] Reactors, also called inductors, are widely used in circuits. Because of the effect of electromagnetic induction in circuits, there is a certain inductance, which can prevent current changes. The inductance of a long straight conductor carrying current is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid form, called an air-core reactor.

[0003] Existing hollow-core reactors, when used in combination, usually fix multiple hollow-core reactors together, and the fixing parts are of an integral structure, which makes it difficult to independently disassemble the multiple hollow-core reactors, and increases the difficulty of maintenance and overhaul. In particular, when a single hollow-core reactor needs to be replaced or adjusted, it may be necessary to disassemble the entire reactor or make major adjustments, affecting the maintenance efficiency of the equipment. Therefore, those skilled in the art provide a combined hollow-core reactor to solve the problems raised in the above background technology. Utility Model Content

At the same time, when it is necessary to disassemble and replace a certain reactor body, it is only necessary to rotate the corresponding hand wheel in the opposite direction to disengage the fixed card block from the fixed card slot, and the reactor body to be replaced can be taken out. The operation is simple and the disassembly and assembly are convenient.
