A compact energy-saving electromagnetic operating mechanism

Abstract

The invention discloses a compact type energy-saving electromagnetic operating mechanism which comprises an electromagnetic mechanism, a counter-force spring and a switch-on and switch-off assembly. The switch-on and switch-off assembly comprises a lever support and a fixed pivot, wherein the lever support is arranged above the electromagnetic mechanism and extends in the horizontal direction, and the fixed pivot enables the lever support to rotate around the lever support. The counter-force spring is connected to one side of the lever support in a hung mode. A movable iron core is connected with the middle appropriate position of the lever support through a matching and connecting structure, and therefore the lever support drives the movable iron core to carry out rectilinear motion without interference through rotation motion. The overall height of the electromagnetic operating mechanism is reduced greatly through the ingenious design of the lever support, and therefore a multifunctional terminal electric appliance using the electromagnetic operating mechanism can be mounted in an electric meter box easily. The compact type energy-saving electromagnetic operating mechanism further comprises an energy-saving mechanism which comprises a lock catch unit and an energy-saving unit. The lock catch unit is used for locking the movable iron core moving to a pull-in position. Meanwhile, the energy-saving unit controls a coil to be powered off, the purpose that the coil of the electromagnetic operating mechanism does not need to be powered on when the electromagnetic operating mechanism is switched on, and a large amount of electric energy is saved.

Description

technical field [0001] The invention relates to an operating mechanism used in circuit breakers, in particular to a compact energy-saving electromagnetic operating mechanism used in multifunctional terminal electrical appliances, and belongs to the technical field of low-voltage electrical accessories. Background technique [0002] The multi-functional terminal appliance refers to the actuator used in conjunction with the smart meter, which is used to accept the instructions sent by the smart meter to open and close the switch, so as to control the user's power on or off. [0003] At present, the commonly used smart meter actuator is a small circuit breaker. When the user owes money, the smart meter sends an opening command to the small circuit breaker, and the small circuit breaker executes the opening, thereby cutting off the power to the arrears users. Through the use of smart meters and actuators, the prepayment mode of electricity is realized, thereby solving the proble...

Problems solved by technology

[0012] Therefore, the technical problem to be solved by the present invention is that the height of the electromagnetic opening and closing mechanism in the "An Electromagnetic Operating Mechanism" submitted by the applicant is too large, and the structure is not compact, resulting in the multi-functional terminal using the electromagnetic opening and closing mechanism The problem that electrical appliances cannot be installed in the commonly used electric meter box due to their high height is too large, so as to provide a compact energy-saving electromagnetic with small height and compact structure, so that the multi-functional terminal electrical appliances can be installed in the commonly used electric meter box operating mechanism
