Relay control mode has the powerful feature of control small in size.But the meeting of the moment due to the load of relay on-off
Higher electric arc is generated, the contact to relay is fatal harm.It just will appear contact " viscous dead " break not open load or touching
The bad phenomenon of point contact.
Summary of the invention
The purpose of the present invention is to provide a kind of voltage over zero high-voltage arcs to inhibit system, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the invention provides the following technical scheme:

Compared with prior art, the beneficial effects of the present invention are: production when the present invention can effectively turn on/off controller
The uncontrollable state of raw electric arc changes into controllable state.The effective service life for extending controller and relay.
Detailed description of the invention
Fig. 1 is structural block diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, embodiment 1: in the embodiment of the present invention, a kind of voltage over zero high-voltage arc inhibits the system to include
Zero-detection circuit, power circuit, MCU control circuit and load circuit；Electric main be separately connected zero-crossing detection circuit and
Power circuit, MCU control circuit are separately connected zero-crossing detection circuit, power circuit and load circuit；
Wherein, load circuit includes relay J1, triode Q2 and bidirectional thyristor Q1, and the base stage of triode Q2 connects resistance
The other end of R9, resistance R9 connect MCU relay control signal, the collector connection relay J1 and diode D5 of triode Q2
Anode, diode D5 cathode connection relay J1 the other end and power supply VCC, the contact shunt of relay J1 is in two-way crystalline substance
The both ends of brake tube Q1, one end of bidirectional thyristor Q1 connect firewire L, and the other end connection load M of bidirectional thyristor Q1 loads M
The other end connect zero curve N.
Bidirectional thyristor Q1 is used with the contact shunt of relay J1, attached in zero crossing first in the moment that load M is connected
Proximity pass two-way thyristor Q1 connects relay after allowing load to connect alternating current again.And when relay J1 be attracted when tip side electricity
Pressure has dropped down to 5V hereinafter, the actuation of contact will not generate electric arc.
When disconnect load M when, the operation of the above process is just on the contrary, first disconnect relay J1, then disconnects bidirectional thyristor Q1.
Above scheme is cleverly utilized bidirectional thyristor Q1 and connects the advantages of load will not generate electric arc, avoids bidirectional thyristor Q1
The advantages of flowing through the shortcomings that high current needs big cooling fin, while capable of flowing through high current using relay J1, avoids relay
J1 on-off generates the shortcomings that electric arc.

In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
