Electric reactor iron core pull rod clamping method and structure

Abstract

The invention relates to an electric reactor iron core pull rod clamping method and structure, and belongs to the technical field of the electric reactor equipment. The technical scheme comprises a bracing plate (1), a foot pad (2), a pull rod (3), a copper pipe (4), an insulating pipe (5) and an electric reactor iron core (6); the bracing plate (1) is arranged at the upper part of the electric reactor iron core (6), the foot pad (2) is located at the lower part of the electric reactor iron core (6), the bracing plate (1), the electric reactor iron core (6) and the foot pad (2) are fixed, clamped and connected through the pull rod (3); the pull rod (3) is arranged in the copper pipe (4), an anti-loose disc spring is arranged between the pull rod (3) and the bracing plate (1), and the insulating pipe (5) is arranged between the pull rod (3) and the foot pad (2). The clamping method disclosed by the invention has the advantages that the iron core is clamped by using the iron core external pull rod, the noise of the iron core is reduced, and the vibration of the electric reactor is reduced; and the problem that the equipment accident is caused since the insulation resistance of the iron core clamp is too low due to the loosening of the structural member is eliminated.

Description

technical field [0001] The invention relates to a method and structure for clamping a reactor iron core pull rod, and belongs to the technical field of reactor equipment. Background technique [0002] The clamping of the reactor core has a great influence on the reactor. The shunt reactor will produce a certain amplitude of vibration during the start-up and operation. If this vibration is not avoided and controlled, it is easy to cause structural parts The looseness of the iron core clamp will cause the insulation resistance of the iron core clamp to be too low, resulting in equipment accidents. The reactor cannot clamp the iron core laminations at the center due to the magnetic flux leakage of the iron core. Therefore, it is necessary to clamp the iron core outside the iron core laminations to reduce the noise of the iron core and the reactor vibration. Contents of the invention [0003] The object of the present invention is to provide a method and structure for clampi...
