In loading board, it is fixed on the upper end of the interlocking pillar in the middle part of the joining beam by pin shaft rotation；A left side for the joining beam
Right both ends are located at below the on/off switch armature of the permanent-magnet AC contactor A and permanent-magnet AC contactor B, and the permanent magnetism is handed over
When the on/off switch armature of stream contactor A or permanent-magnet AC contactor B moves downward closing locking, described in on/off switch armature pushing
The on/off switch that joining beam one end makes the joining beam other end push against another permanent-magnet AC contactor A or permanent-magnet AC contactor B upwards is held in the mouth
Iron prevents it to keep gate-dividing state from closing a floodgate.
As a further improvement of the utility model, when the permanent-magnet AC contactor A and permanent-magnet AC contactor B its
In a closing locking when, the switching force of another permanent magnet AC vacuum contactor is not more than the permanent magnet AC vacuum closed a floodgate and connects
The magnetic of tentaculum keeps maintenance energy.
Two contacts of the magneto modular contact interlocking mechanism as a further improvement of the utility model,
Closing circuit between device is locked using Electricity Federation.
The control voltage of the Electricity Federation lock is to power for pulse 1 second as a further improvement of the utility model,.
The beneficial effects of the utility model are: using mechanical structure as mutual interlocking gear, while closing a floodgate between two contactors
Circuit 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；It is former without changing
Equipment electrical control circuit, does not increase cost, and anti-misoperation is good；The number of parts of use is few, and structure is simple, at low cost, long
It is service life, 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, not deposit
The security risks such as fire are enclosed online；Permanent magnet type vacuum contactor has been used, when two contactors are energized simultaneously combined floodgate, essence
There is no occur combined floodgate jump or state overturning.
Detailed description of the invention
Fig. 1 is the utility model in two contactors while being in gate-dividing state structural schematic diagram；
Fig. 2 is status architecture schematic diagram of the utility model 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 utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It refering to fig. 1-2, is a kind of magneto modular contact interlocking mechanism described in the utility model, including interlocking peace
Loading board 1, interlocking pillar 2, joining beam 3, permanent-magnet AC contactor A4, pin shaft 5 and permanent-magnet AC contactor B 6, the permanent magnet AC
Contactor A4, permanent-magnet AC contactor B 6 are symmetrically arranged on the interlocking mounting plate 1；The interlocking pillar 2 be located at it is described forever
Between magnetic A.C. contactor A4 and permanent-magnet AC contactor B6, the interlocking mounting plate 1 is fixed in the bottom of the interlocking pillar 2
On, 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 of the joining beam
Both ends are located at 7 lower section of on/off switch armature of the permanent-magnet AC contactor A4 and permanent-magnet AC contactor B6, the permanent magnetism
When the on/off switch armature 7 of A.C. contactor A4 or permanent-magnet AC contactor B6 moves downward closing locking, under the on/off switch armature 7
Press described 3 one end of joining beam that 3 other end of joining beam is made to push against another permanent-magnet AC contactor A4 or permanent-magnet AC contactor B6 upwards
On/off switch armature 7 prevent its 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.
