Abstract
The invention discloses an electronic breaker mechanism. The electronic breaker mechanism comprises a housing, a left static contact and a right static contact are respectively and fixedly installed on two sides in the housing, a lever is rotationally installed between the left and right static contacts in the housing, a left moving contact corresponding to the left static contact and a right moving contact corresponding to the right static contact are respectively and fixedly installed at two ends of the lever, a support is fixedly installed under the lever in the housing, a coil is fixedly installed on the support, an iron core is installed in the coil in an inserting manner, and a permanent magnet is fixedly installed below the iron core on the support; and a handle is rotationally installed at the upper part of the housing, a transmission rod is hinged at a position corresponding to an operation part of the handle on the handle, and the lower end of the transmission rod is hinged with the lever. An action mechanism is simple, the electronic breaker mechanism can achieve rapid closing and breaking and has the advantage of the large current-carrying capacity, the electronic breaker mechanism has an obvious advantage especially while a short-circuit surge, and the electronic breaker mechanism overcomes the defect that an electronic breaker in the prior art only can be applied to a small-current place and the defect of the poor overload capacity of the electronic breaker in the prior art.
Description
Technical field
The present invention relates to miniature circuit breaker field, specifically a kind of electronic breaker mechanism.
Background technology
In prior art, in electronic breaker, circuit breaker is realized by electronic component from the action of disjunction of threading off mostly, does not have actuating mechanism; Cause product can only be applied to small area analysis place, and overload capacity is poor.
Summary of the invention
The object of this invention is to provide a kind of electronic breaker mechanism, to overcome in prior art electronic breaker due to small area analysis place can only be applied to, and the shortcoming of overload capacity difference.
Technical scheme of the present invention is as follows:
A kind of electronic breaker mechanism, include housing, it is characterized in that: the both sides in described housing are installed with left and right fixed contact respectively, lever is rotatablely equipped with between left and right fixed contact described in housing inherence, the two ends of described lever are installed with the left and right moving contact with described left and right fixed contact corresponding matching respectively, the below of the inherent described lever of described housing is installed with support, described support is installed with coil, be fitted with iron core in described coil, described support is installed with permanent magnet in the below of described iron core; The top of described housing is rotatablely equipped with handle, and described handle is hinged with drive link in the position relative with its operating position, and lower end and the described lever of described drive link are hinged.
Described electronic breaker mechanism, is characterized in that: be connected with spring between the side of described support and described lever.
Described electronic breaker mechanism, is characterized in that: the rear end of described left and right fixed contact is connected to wire, and described wire is drawn respectively in described housing.
Beneficial effect of the present invention:
The present invention compares with prior art, its effect is actively with obvious, the present invention adopts electronic devices and components and actuating mechanism to form in electronic breaker, the sampling of current signal and the signal of switch motion are exported and controls to realize by electronic device, perform closed quick disjunction to be completed by actuating mechanism, both overcome electronic breaker and be difficult to break-make big current and the negative effect and the insoluble unsteadiness of mechanical type circuit breaker that produce temperature effect, sensitivity is low, there is complex structure, the shortcoming of the problems such as assembling difficulty, current collection minor circuit breaker is highly sensitive again, reaction speed is fast, the advantage of good stability and mechanical type circuit breaker energy break-make big current is in one, the desirable substitute products of current circuit breaker, its properties of product are stablized, without temperature rise, the impact of ambient temperature can not be subject to and misoperation, also large electric arc can not be produced, extend the useful life of circuit breaker, its mechanism is simple, highly sensitive, cost is low, volume is little, microminiaturized, easy to manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
See Fig. 1, a kind of electronic breaker mechanism, include housing 11, both sides in housing 11 are installed with left and right fixed contact 7,13 respectively, lever 9 is rotatablely equipped with between the inherent left and right fixed contact 7,13 of housing 11, the two ends of lever 9 are installed with the left and right moving contact 8,14 with left and right fixed contact 7,13 corresponding matching respectively, the below of the inherent lever 9 of housing 11 is installed with support 2, support 2 is installed with coil 5, be fitted with iron core 4 in coil 5, support 2 is installed with permanent magnet 3 in the below of iron core 4; The top of housing 11 is rotatablely equipped with handle 12, and handle 12 is hinged with drive link 10 in the position relative with its operating position, and lower end and the lever 9 of drive link 10 are hinged.
In the present invention, the side of support 2 is fixedly connected with spring base 6, is connected with spring 1 between spring base 6 and lever 9; The rear end of left and right fixed contact 7,13 is connected to wire, and wire is drawn respectively in housing 11, forms loop with power supply and load.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
When handle 12 rotates counterclockwise, drive link 10 moves downward under the drive of handle 12, and lever 9 produces and deflects and drive the corresponding and left and right fixed contact 7,13 of left and right moving contact 8,14 difference to close; Otherwise, the then disjunction when handle 12 rotates clockwise.
After above-mentioned dynamic/static contact is closed, due to coil 5 being fitted with iron core 4, the magnetic force of permanent magnet 3 holds lever 9 by the conduction of iron core 4, thus keeps above-mentioned dynamic/static contact to be in closure state, whole circuit closed.When coil 5 is energized, coil 5 just produces a kind of reverse magnetic force and overcomes the magnetic force falling permanent magnet 3, and lever 9 resets and drives left and right moving contact 8,14 to be separated with left and right fixed contact 7,13 respectively under the effect of spring 1, and whole loop disconnects.
