Background technique
Currently, AC vacuum contactor work when, secondary circuit in making process, need by normally closed auxiliary contact into
The switching of row powerful actuating coil and low power Energy-saving coil.Auxiliary contact will appear high current arcing when switching, and touch
Head scaling loss is larger, keeps the service life of auxiliary contact shorter.When auxiliary contact adjust improper or disabling damage, it may appear that jump of closing a floodgate
Phenomenon.Continuous on-off can generate high overvoltage in the main circuit current short time when jump, will cause major loop breakdown, cause
Major accident brings heavy losses.When dimensions of mechanical structures changes, easily there is normally closed auxiliary contact and switch nothing not in place
Method is opened, and coil can cause heating burnout to fail because that can not switch.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of Energy-saving coil No-contact switch formula vacuum contactor control electricity
Road.
The present invention is to solve technical solution used by its technical problem: a kind of Energy-saving coil No-contact switch formula is true
Empty contactor control circuit, including rectification circuit, switching voltage Threshold detection circuit, actuating coil, closing pulse generative circuit,
VMOS pipe and Energy-saving coil, after the rectification circuit is sequentially connected switching voltage Threshold detection circuit and closing pulse generative circuit
It is connected to the pole G of VMOS pipe；Described actuating coil one end be connected to the rectification circuit and switching voltage Threshold detection circuit it
Between, the other end is connected to the pole D of the VMOS pipe；The both ends of the Energy-saving coil are respectively connected to the pole D and the S of the VMOS pipe
Pole.
As a further improvement of the present invention, whether the switching voltage Threshold detection circuit detection switching voltage, which reaches, is wanted
The setting value asked issues combined floodgate trigger command when switching voltage reaches setting value and closes a floodgate to contactor.
As a further improvement of the present invention, when contactor closes a floodgate, the closing pulse generative circuit issues 0.1~0.5
The closing pulse of second pulsewidth, triggering VMOS pipe make Energy-saving coil be bypassed short circuit, and actuating coil makes contactor when passing through high current
It closes a floodgate；Contactor in-place closing at the end of closing pulse, VMOS pipe is closed at this time, and Energy-saving coil is switched to actuating coil
Series connection carries out low-power consumption and maintains combined floodgate work；After contactor power-off, electromagnet coil magnetic field disappears, and vacuum contactor is dividing
Separating brake is completed under lock thrust.
The beneficial effects of the present invention are: 1, avoid the occurrence of the generation of combined floodgate chattering, the normal on-off of major loop will not generate
Overvoltage causes major loop to puncture；2, actuating coil only has brief energization in contactor making process, will not be closed by external action
It keeps low-power consumption to maintain after lock, coil will not be burnt；3, there are voltage threshold detection, coil No-contact switch, debugging letter when closing a floodgate
It is single, at low cost, reliability is high, long-life and non-maintaining.
Detailed description of the invention
Fig. 1 is structure of the invention schematic illustration.
In conjunction with attached drawing, make the following instructions:
1 --- rectification circuit；2 --- switching voltage Threshold detection circuit；
3 --- actuating coil；4 --- closing pulse generative circuit；

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, is a kind of Energy-saving coil No-contact switch formula vacuum contactor control circuit of the present invention, including
Rectification circuit 1, switching voltage Threshold detection circuit 2, actuating coil 3, closing pulse generative circuit 4, VMOS pipe 5 and Energy-saving coil
6, the rectification circuit 1 is connected to VMOS pipe after being sequentially connected switching voltage Threshold detection circuit 2 and closing pulse generative circuit 4
5 pole G；Described 3 one end of actuating coil is connected between the rectification circuit 1 and switching voltage Threshold detection circuit 2, the other end
It is connected to the pole D of the VMOS pipe 5；The both ends of the Energy-saving coil 6 are respectively connected to the pole D and the pole S of the VMOS pipe 5.
Wherein, the switching voltage Threshold detection circuit 2 detects the setting value whether switching voltage reaches requirement, works as combined floodgate
Voltage issues combined floodgate trigger command when reaching setting value and closes a floodgate to contactor.When contactor closes a floodgate, the closing pulse generates electricity
Road 4 issues the closing pulse of 0.1~0.5 second pulsewidth, and triggering VMOS pipe makes Energy-saving coil be bypassed short circuit, and actuating coil passes through big
Contactor is set to close a floodgate when electric current；Contactor in-place closing at the end of closing pulse, VMOS pipe is closed at this time, Energy-saving coil with
Actuating coil is switched to series connection, carries out low-power consumption and maintains combined floodgate work；After contactor power-off, electromagnet coil magnetic field disappears,
Vacuum contactor completes separating brake under separating brake thrust.
The specific work process of the Energy-saving coil No-contact switch formula vacuum contactor control circuit are as follows: when logical to contactor
When electric, the rectification circuit converts alternating current to direct current, and actuating coil and Energy-saving coil series connection small-power work, connect at this time
Tentaculum is in gate-dividing state, while whether the combined floodgate threshold voltage detection circuit sustained sensed voltage reaches setting value, when reaching
To or more than setting value when determine to allow to close a floodgate, and trigger closing pulse generative circuit, issue the combined floodgate of 0.1~0.5 second pulsewidth
Pulse, the closing pulse pulse are sent to the pole G of VMOS pipe, and VMOS pipe is connected, and Energy-saving coil is bypassed short circuit at this time, start line
Circle makes contactor close a floodgate under high-power driving by high current；After closing pulse, VMOS pipe ends, at this time energy saving line
Circle is connected again with actuating coil, and contactor carries out low-power consumption and maintains combined floodgate working condition, the electricity of combined floodgate threshold voltage detection at this time
Road locking no longer does voltage detecting until power-off restoration；After contactor power-off, electromagnet coil magnetic field disappears, vacuum contact
Device completes separating brake under separating brake thrust.
It can be seen that the Energy-saving coil No-contact switch formula vacuum contactor control circuit avoids the occurrence of combined floodgate chattering
Occur, the normal on-off of major loop, will not generate overvoltage causes major loop to puncture；Actuating coil only has in contactor making process
Brief energization will not be kept low-power consumption to maintain, will not burn coil by external action after combined floodgate；There is voltage threshold inspection when combined floodgate
It surveys, coil No-contact switch, debugs that simple, at low cost, reliability is high, long-life and non-maintaining.
