Abstract

The invention provides an actuating mechanism and a switching device, and belongs to the technical field of low-voltage electrical appliances. The actuating mechanism comprises a static metal core fixedly arranged on a base; a moving metal core is in driving connection with a moving contact assembly; one end of a first elastic member is connected with the static metal core; and the other end of the first elastic member is connected with the moving metal core; a coil is wound on the moving metal core and / or the static metal core, and is used for enabling the moving metal core to move towards the static metal core through magnetic field force to drive the moving contact assembly to be conducted with a static contact when the coil is forwards electrified; when the coil is reversely electrified, the moving metal core is enabled to move towards the direction far away from the static metal core through the reset force of the first elastic member so as to drive the moving contact assembly tobe separated from the static contact. Magnetic control is adopted to be matched with the first elastic member, so that the opening and closing speed of the actuating mechanism can be increased, quickswitching between two sections of incoming power supplies can be realized in a shorter time, and the stability of continuous operation of important electric equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an action mechanism and a switching device. Background technique [0002] Petroleum, chemical, fiber, metallurgy, finishing and other power-consuming enterprises, due to failure or abnormality of the external main power supply network, unplanned power outages, large voltage fluctuations or short-term power outages are not uncommon. The particularity of power supply interruption or abnormality will often cause equipment shutdown or idling, process flow interruption or waste production, and sometimes even cause serious consequences such as scrapping of production equipment. [0003] At present, in such enterprises that require continuous power supply, they basically use low-voltage backup and automatic switching to realize the mutual switching between the two incoming power supplies. However, due to the long switching time of the standby automatic switch,...
