Abstract

The present invention proposes a low-power AC and DC extension module for an AC contactor, which is designed to be coupled with the AC contactor through a connecting device located on the extension module. The extension module includes a rectifier module, a protection module, a current regulating element and a Linkage state switching module, wherein: the rectification module can be electrically connected to the linkage state switching module and the pull-in coil of the AC contactor, and is used to convert alternating current into direct current; the protection module can protect the low-power AC and DC expansion module from the power supply Damage due to impact of voltage changes; the current adjustment element can be electrically connected to the linkage state switching module and the pull-in coil of the AC contactor for adjusting the level of the maintenance current; and, the linkage state switching module is configured to respond to the main contact of the AC contactor The action of the head selectively connects the current regulating element and the pull-in coil of the AC contactor in series.

Description

technical field [0001] The invention relates to the technical field of contactors, in particular to a low-power AC / DC expansion module for an AC contactor. Background technique [0002] Contactors are widely used in various electrical occasions, including AC contactors and DC contactors. When the coil of the contactor is energized, the current flows through the coil to generate a magnetic field, thereby driving the main contact of the contactor to move, so as to achieve the purpose of controlling the closing or opening of the load circuit. [0003] There are three main types of contactor coil designs today. [0004] The first type is figure 1 For the traditional AC coil design shown, the corresponding coil winding parameters are designed for each rated input voltage and frequency (usually 50Hz) to meet the action characteristics (pick-up voltage, release voltage, pull-in time, release time, speed, etc. etc.), the coil winding parameters must be adjusted when the rated inp...
