Abstract

The invention provides an apparatus of an interlock AC contactor. The problems of a complex structure, few components and a large occupation space of an existing interlock contactor formed by two individual contactors and one interlock apparatus are solved. The apparatus of the interlock AC contactor comprises a first AC contactor and a second AC contactor which are arranged side by side and also comprises an interlock piece which is installed in the first AC contactor or the second AC contactor in a swinging, through the swinging position of the interlock piece, the turn-on of only one AC contactor at most in each time is realized, the interlock is realized, the structure is simple, and the apparatus is convenient to use.

Description

technical field [0001] The invention relates to the field of contactors, in particular to a device for interlocking AC contactors. Background technique [0002] In the widely used card-mounted low-voltage electrical appliances, such as a reversible contactor group composed of two contactors, in order to ensure its normal and safe operation, it is required to have a mechanical interlock function between the two contactors, that is, when any of them When one contactor is in the on state, the other contactor cannot be connected, that is, it is locked in the off state. [0003] Taking the contactor as an example, the currently widely used interlocking contactor consists of two separate contactors and an interlocking device. The existing interlocking device has a complex structure, many parts, and takes up a large space . Contents of the invention [0004] In order to overcome the shortcomings of the background technology, the present invention provides a device for interlock...
