An energy-saving mechanism used in conjunction with an electromagnetic opening and closing mechanism

Abstract

The invention discloses an energy-saving mechanism cooperating with an electromagnetic switching-on and switching-off mechanism for use. The energy-saving mechanism comprises a lock catch unit, an energy-saving unit, an automatic tripping unit and a hand-operated tripping unit. The moving iron core of an electromagnetic mechanism moves to an attracting position the instant when a coil is energized, the lock catch unit enables the moving iron core to maintain motionless at the attracting position through a mechanical lock catch structure formed between the lock catch unit and the moving iron core, and at the same time, the energy-saving unit controls the coil to be de-energized the instant when the moving iron core is deviated from an initial position, such that zero power consumption is realized when the electromagnetic switching-on and switching-off mechanism works, and enormous electric energy is reduced; the automatic tripping unit, when a user has an overdue bill, receives a tripping instruction and acts, and triggers the mechanical lock catch structure formed by the lock catch unit and the moving iron core to release a lock catch so as to realize automatic switching-off; and the hand-operated tripping unit, when an intelligent ammeter or a multifunctional terminal electric appliance needs overhaul or maintenance, triggers the mechanical lock catch structure formed by the lock catch unit and the moving iron core in a hand-operated mode to release the lock catch so as to realize hand-operated switching-off.

Description

technical field [0001] The invention relates to a smart meter actuator used in conjunction with a smart meter, in particular to an energy-saving mechanism used in conjunction with an electromagnetic opening and closing mechanism in the smart meter actuator, and belongs to the technical field of low-voltage electrical accessories. Background technique [0002] Smart grid refers to the intelligence of the power grid. Its purpose is to provide a fully automated power transmission network that can monitor and control each user and grid node, and ensure information between all nodes in the entire transmission and distribution process from the power plant to the end user. and bidirectional flow of electrical energy. [0003] The smart meter is the smart terminal of the smart grid. It is no longer a meter in the traditional sense. In addition to the basic power consumption measurement function of the traditional meter, the smart meter also has two-way multiple tariffs in order to a...
