Abstract

The invention discloses a structure for improving vibration performance of a contactor. The structure comprises an elastic damping spacer arranged on a yoke on the part of a magnetic circuit in a point welding mode. A U-type elastic piece stretching upwards is arranged outside the elastic damping spacer and makes contact with the inner lateral wall of a cover. The elastic damping spacer is further provided with a positioning supporting piece, and the positioning supporting piece stretches downwards to make contact with the inner bottom surface of the cover. Finite element analysis is adopted in the structure, through changes of positioning and installing modes of contact of inner final assembly parts in the contactor and the cover part and the additional arrangement of the elastic damping spacer, the problems that because coils are too heavy, the centers of the coils deviate from the axes, the overall gravity center of the coils and the overall centroid of the coils are not symmetric, the cover is not tightly connected with a machine core, restraints on the heavy coils are not enough, and accordingly in the vibration compact process of the contactor, the resonance point descends, and the contactor is subject to vibration and impact when used under poor environment and loses efficiency are solved.

Description

[0001] technical field [0002] The invention relates to a structure for improving the vibration performance of a contactor, which belongs to the technical field of contactors. Background technique [0003] Three-phase AC contactors play an irreplaceable key role in the transmission and distribution of electric energy and the control and protection of electrical equipment. The three-phase AC contactor is an electrical appliance suitable for long-distance frequent switching on and off of the AC main circuit and large-capacity control circuit under the rated working voltage. At the same time, with the improvement of the level of science and technology, the degree of automation of production, processing and manufacturing is getting higher and higher, and the control system of electrical equipment is becoming more and more complex. As an important part of the control system, the three-phase AC contactor has a large demand and a wide range of applications. There are many types, ...
