Embodiment 1

[0067] Such as Figure 1-2 Shown is the preferred embodiment of the electromagnetic operating mechanism of the present invention. The electromagnetic operating mechanism is mainly used in a circuit breaker dedicated to smart meters, and includes an electromagnetic mechanism.

[0068] Such as figure 1 and Figure 10 As shown, the electromagnetic mechanism includes an electromagnet 11, and the electromagnet includes a housing 1101, a coil 1103 fixed in the housing 1101, and a static iron core 1102, and is arranged on the coil 1103 so as to reciprocate and move linearly. The moving iron core 1104 inside, the moving iron core 1104 has an initial position before the coil 1103 is energized and moves from the initial position to the static iron core 1102 under the action of electromagnetic attraction generated at the moment when the coil 1103 is energized the pull-in position; the reaction force spring 1420 is applied to the axial reaction force of the moving iron core 1104, and t...

Embodiment 2

[0088] As an alternative structure of the reset member 1415 in the energy-saving mechanism in Embodiment 1, in this embodiment, the reset member 1415 is the first triggered part 1412b of the locking member 1412, and the first triggered part After the tripping end 1414 is triggered, the triggering part 1412 b pushes the tripping end 1414 back to the return position under the action of the biasing force of the biasing member 1403 . In this embodiment, the structure and working method of the first triggered part 1412b and the biasing part 1403 are fully utilized, and the first triggered part 1412b is used as a reset part, when the tripping end of the tripping unit After triggering the first triggered part 1412b so that the first triggered part 1412b rotates at a small angle in the triggering direction, the first triggered part 1412b rotates in the opposite direction again under the biasing force of the biasing member , so as to push the tripping end 1414 back to its return positi...

Abstract

An electromagnetic operating mechanism used in a circuit breaker for smart meters, including an electromagnetic mechanism and an energy-saving mechanism. The electromagnetic mechanism includes an electromagnet, a reaction force spring, and a transmission mechanism; The moving iron core of the iron moves to its suction position when the coil is energized, and the locking unit forms a locking structure with the moving iron core to keep the moving iron core at the suction position. At the same time, the energy-saving unit Immediately after the moving iron core leaves the initial position, the control coil is powered off, thereby realizing zero power consumption when the electromagnetic mechanism is working, and saving a lot of electric energy; the tripping unit can receive the tripping command to trigger the locking unit to unlock the locking structure, so that the The moving iron core quickly returns to its original position, and the trip unit can return to its return position after tripping for the next use.

Description

technical field [0001] The invention relates to an electromagnetic operating mechanism, which can be used in a special circuit breaker for an intelligent electric meter, and belongs to the technical field of low-voltage electric appliance accessories. Background technique [0002] 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 adapt to the use of smart grid and new energy. Intelligent functions such as metering function, user terminal control function, two-way data communication function of multiple data transmission modes, and anti-theft function, smart meters represent the development direction of future energy-saving smart grid end-user intelligent terminals. [0003] Smart meters are often used in conjunction with special circuit breakers. At present, the commonl...
