Further, described first contact, the 4th contact, the 7th contact, the tenth contact are normally-closed contact, remaining contact
For normally opened contact.
Further, described first group relay and the second group relay pass through interlocking and circuit control are specifically included:
The normally closed auxiliary contact of the first group relay is serially connected in control one end of zl2, the normally closed auxiliary of corresponding the second group relay
Contact will be connected with control one end of zl1, play interlocked and use.When zl1 runs, the startup of zl2 can be returned by relay normally closed contact
Road disconnects.The normally closed auxiliary contact of four two group relays, mutually makes the other side can not energized action simultaneously between two groups.
After first group relay action, k1b, k2b, k1c, k2c adhesive, k3b, k4b simultaneously, k3c, k4c disconnect, kz1,
Kz2 is connected with+pp ,-pp loop and obtains forward voltage.Second group relay action, k3a, k4a disconnect, then zl1 loop disconnects.
K3b, k4b, k3c, k4c adhesive, k1b, k2b simultaneously, k1c, k2c disconnect, and kz1, kz2 are connected with-pp ,+pp loop and obtain reversely
Voltage.
Further, one group of two relay Redundancy Design, when any one in the first group relay, the second group relay
Individual relay failure will not produce impact to interlock circuit.
This circuit passes through the first group relay, the second group relay composition output logic mutual exclusion it is ensured that the control of two states
Circuit processed can only send a kind of state in synchronization, be prevented effectively from and be simultaneously emitted by control signal and lead to control signal short circuit to cause
Fault, the effect of interlocking is in order to avoid the contact competition in relay major loop produces adverse consequencess.One group is continued using two
The Redundancy Design of electrical equipment, can improve the reliability of control circuit.
This utility model realizes by relay interlock circuit that control circuit is simple, interlocking avoids mistake that associated loop is made
Become damaging influence, two-way Redundancy Design avoids individual devices to lose efficacy and causes the inefficacy of interlock circuit, improves control circuit
Safety and reliability.
Brief description
Fig. 1 interlocks conversion control circuit composition frame chart for the relay that this utility model embodiment provides.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.Additionally, institute in each embodiment of this utility model disclosed below
As long as the technical characteristic being related to does not constitute conflict each other just can be mutually combined.
In order to improve control circuit dependability, safety, using relay logic mutual exclusion interlocked control design principle,
Driven by external command, the teamwork of many group relays is realized control circuit state and reliably changed.In order to realize to relay
The requirement that interlock circuit control effectively, this utility model provides a kind of interlock circuit of Control；As Fig. 1 institute
Show, the normally closed auxiliary contact of two group relays be connected in series in the starting-up later time of other side that is to say, that the first group relay normally closed
Auxiliary contact is serially connected in control one end of zl2, and the normally closed auxiliary contact of the second corresponding group relay will be with the control one of zl1
End series connection, plays interlocked and uses.When zl1 runs, the starting-up later time of zl2 can be disconnected by relay normally closed contact.Four two groups of relays
The normally closed auxiliary contact of device, mutually makes the other side can not energized action simultaneously between two groups.
Its operation principle particularly as follows: when zl1 sends, the first group relay (k1, k2) action, k1a, k2a disconnect, then zl2
Loop disconnects.K1b, k2b, k1c, k2c adhesive, k3b, k4b simultaneously, k3c, k4c disconnect, and kz1, kz2 are connected with+pp ,-pp loop
Obtain forward voltage, thus promoting outside high current actuator to realize correlation function；If zl2 sends, the second group relay
(k3, k4) action, k3a, k4a disconnect, then zl1 loop disconnects.K3b, k4b, k3c, k4c adhesive, k1b, k2b simultaneously, k1c, k2c
Disconnect, kz1, kz2 are connected with-pp ,+pp loop and obtain backward voltage, thus it is related to promote outside high current actuator to realize
Function.When arbitrary relay failure in the first group relay (k1, k2), the second group relay (k3, k4) will not be to interlock circuit
Produce impact.This circuit is simple, interlock, two-way redundancy protecting perfects, and can be applicable to the practicality such as DC motor positive and negative rotation control
In higher control circuit.
This utility model passes through relay mutual exclusion chain control circuit state and locks, and not only increases the reliability of control circuit
Property, also improve the safety of operation, effectively prevent the risk that maloperation brings.
