Permanent-magnet AC contactor A, permanent-magnet AC contactor B are symmetrically arranged on the interlocking mounting plate；The interlocking pillar is located at institute
It states between permanent-magnet AC contactor A and permanent-magnet AC contactor B, the interlocking mounting plate is fixed in the bottom of the interlocking pillar
On, it is fixed on the upper end of the interlocking pillar in the middle part of the joining beam by pin shaft rotation；The left and right two of the joining beam
End is located at below the on/off switch armature of the permanent-magnet AC contactor A and permanent-magnet AC contactor B, and the permanent magnet AC connects
When the on/off switch armature of tentaculum A or permanent-magnet AC contactor B moves downward closing locking, which pushes the joining beam
One end, which makes the joining beam other end push against another permanent-magnet AC contactor A or the on/off switch armature of permanent-magnet AC contactor B upwards, to be made
It keeps gate-dividing state that cannot close a floodgate.
As a further improvement of the present invention, when wherein the one of the permanent-magnet AC contactor A and permanent-magnet AC contactor B
When platform closing locking, the switching force of another permanent magnet AC vacuum contactor is not more than the permanent magnet AC vacuum contactor to have closed a floodgate
Magnetic keep maintenance energy.
As a further improvement of the present invention, two contactors of the magneto modular contact interlocking mechanism it
Between closing circuit using Electricity Federation lock.
As a further improvement of the present invention, the control voltage of the Electricity Federation lock is to power for pulse 1 second.
The beneficial effects of the present invention are: using mechanical structure as mutual interlocking gear, while closing circuit between two contactors
It is locked using Electricity Federation, mechanical electric dual fail-safe, than only having the other way work more secure and reliable of Electricity Federation lock；Without changing original equipment
Electric control loop, does not increase cost, and anti-misoperation is good；The number of parts of use is few, and structure is simple, at low cost, the long-life,
It is non-maintaining；Contactor uses magnetic hold mode, and control mode is double command pulse power supplies, does not need to power for a long time, line is not present
Enclose the security risks such as fire；Permanent magnet type vacuum contactor is used, when two contactors are energized simultaneously combined floodgate, essence is not deposited
The problem of occurring to close a floodgate jump or state overturning.
Detailed description of the invention
Fig. 1 is the present invention in two contactors while being in gate-dividing state structural schematic diagram；
Fig. 2 is status architecture schematic diagram of the present invention when a contactor closes a floodgate.
In conjunction with attached drawing, make the following instructions:
1 --- interlocking mounting plate；2 --- interlocking pillar；
3 --- joining beam；4 --- permanent-magnet AC contactor A；
5 --- pin shaft；6 --- permanent-magnet AC contactor B；
7 --- on/off switch armature
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the invention.But protection scope of the present invention is not
Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair
Decorations, all still belong within the invention patent covering scope.
It refering to fig. 1-2, is a kind of magneto modular contact interlocking mechanism of the present invention, including interlocking mounting plate
1, pillar 2, joining beam 3, permanent-magnet AC contactor A4, pin shaft 5 and permanent-magnet AC contactor B 6, the permanent magnet AC contact are interlocked
Device A4, permanent-magnet AC contactor B 6 are symmetrically arranged on the interlocking mounting plate 1；The interlocking pillar 2 is located at permanent magnetism friendship
It flows between contactor A4 and permanent-magnet AC contactor B6, the bottom of the interlocking pillar 2 is fixed on the interlocking mounting plate 1,
It is fixed on the upper end of the interlocking pillar 2 in the middle part of the joining beam 3 by the pin shaft 5 rotation；The left and right two of the joining beam
End is located at 7 lower section of on/off switch armature of the permanent-magnet AC contactor A4 and permanent-magnet AC contactor B6, and the permanent magnetism is handed over
When the on/off switch armature 7 of stream contactor A4 or permanent-magnet AC contactor B6 moves downward closing locking, which is pushed
Described 3 one end of joining beam makes 3 other end of joining beam push against another permanent-magnet AC contactor A4's or permanent-magnet AC contactor B6 upwards
On/off switch armature 7 prevents it to keep gate-dividing state from closing a floodgate.
The mechanism is after integral installation is good, when permanent magnet AC vacuum contactor A, B are in gate-dividing state, any permanent magnetism
AC vacuum contactor can free splitting or integrating lock.
When any permanent magnet AC vacuum contactor is in combined floodgate Self-closing lock, on/off switch armature 7 can be by joining beam
One end pressure, makes the joining beam other end tilt the on/off switch armature 7 for withstanding another permanent magnet AC vacuum contactor, to make its nothing
Method is closed a floodgate, i.e., the mechanism does not allow two permanent magnet AC vacuum contactors while being in "on" position, but allows while being in divide
Lock state, to achieve the purpose that permanent magnet AC vacuum contactor A and B mechanical interlocking.
The joining beam can slightly be swung, and buffering permanent magnet AC vacuum contactor is attracted the impact of moment, high reliablity.Two
Closing circuit is locked using Electricity Federation between contactor, i.e., connects the normally closed auxiliary that other side is sealed in the shutting-brake control loop of every contactor
Point.Mechanical electric dual fail-safe, than only having the other way work more secure and reliable of Electricity Federation lock.Using double order control modes, control
Voltage processed is to power for pulse 1 second, keeps after combined floodgate for magnetic, does not need to power for a long time.Coil is burnt there is no long-time energization to ask
Topic.
When a wherein combined floodgate Self-closing lock for two permanent magnet AC vacuum contactors, another permanent magnet AC vacuum contact
The magnetic that the switching force of device is not more than the permanent magnet AC vacuum contactor to have closed a floodgate keeps maintenance energy, guarantees two permanent magnet AC vacuum
Contactor is powered simultaneously when closing a floodgate, and will not generate shake and State-jump turning problem.
It can be seen that the interlocking mechanism using mechanical structure as mutual interlocking gear, while closing circuit between two contactors
It is locked using Electricity Federation, mechanical electric dual fail-safe, than only having the other way work more secure and reliable of Electricity Federation lock；Without changing original equipment
Electric control loop, does not increase cost, and anti-misoperation is good；The number of parts of use is few, and structure is simple, at low cost, the long-life,
It is non-maintaining；Contactor uses magnetic hold mode, and control mode is double command pulse power supplies, does not need to power for a long time, line is not present
Enclose the security risks such as fire；Permanent magnet type vacuum contactor is used, when two contactors are energized simultaneously combined floodgate, essence is not deposited
The problem of occurring to close a floodgate jump or state overturning.
