Abstract
The utility model discloses a kind of self-locking based on electromagnetic controller and multiple control circuit,By connections terminal,First relay and the second relay group into,Second relay is in long-term off-state,By the break-make of the first relay control circuit,When the first relay goes wrong,Closure state can be in,Now the second relay just can in time instead of the break-make of the first relay control circuit,When the second relay is in closure state,No matter the first relay is in disconnecting or closure state,Circuit is constantly in conducting state,Circuit is controlled using two relays,The timely substitute and the emergency lock to relay to damaging relay are reached by way of the modification of circuit,Prevent accident,The damage if one of relay goes wrong,Also circuit will not be had any impact,It is easy to use,It is flexible and changeable.
Description
Technical field
The utility model is related to a kind of control circuit for controlling forceful electric power break-make by light current change, and specially one kind is based on
The self-locking of electromagnetic controller and multiple control circuit.
Background technology
At present, known control relay circuit be by single triode, some resistance and relay group into.By light current
It is connected to the base stage of triode i.e. the control end of control relay circuit, the drive circuit required for cut-in relay is corresponding
Power supply and control strong power part, after the voltage of weak current part changes, relay can make corresponding break-make
Action.General control relay circuit is easily damaged, and causes the situation of uncontrollable circuit, it is impossible to changed immediately, and
Controlled device cisco unity malfunction is caused after damage.
Utility model content
In order to solve existing relay damaged without timely substitute component and damage the deficiency of locking, this practicality is new
Type provides a kind of self-locking and multiple control circuit based on electromagnetic controller, the circuit can not only solve relay damaged without and
When substitute component problem, moreover it is possible to damage relay lock, allow controlled device to carry out normal work.
To achieve the above object, the utility model provides following technical scheme：A kind of self-locking based on electromagnetic controller and
Multiple control circuit, by connections terminal, the first relay and the second relay group into second relay is in long-term
Off-state, by the break-make of the first relay control circuit, when relay goes wrong, can be in closure state, now
Second relay just can in time replace the break-make of the first relay control circuit, when the second relay is in closure state, no
It is in by the first relay and is disconnected or closure state, circuit is constantly in conducting state.
Compared with prior art, the beneficial effects of the utility model are：The utility model is using two relays come to line
Road is controlled, and timely substitute and the urgent lock to relay to damaging relay are reached by way of the modification of circuit
It is fixed, accident is prevented, the damage if one of relay goes wrong will not also have any impact to circuit, user
Just, it is flexible and changeable.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
1- connections terminals；2- relays；3- relays.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 is referred to, the utility model provides a kind of technical scheme：A kind of self-locking and multiple control based on electromagnetic controller
Circuit processed, is made up of connections terminal 1, the first relay 2 and the second relay 3, and second relay 3 is long-term
Off-state, by the break-make of the control circuit of the first relay 2, when the first relay 2 goes wrong, can be in closure state,
Now the second relay 3 just can in time instead of the break-make of the control circuit of the first relay 2, when the second relay 3 is in closed form
During state, no matter the first relay 2 is in disconnection or closure state, circuit is constantly in conducting state.
The utility model is controlled using two relays to circuit, is reached by way of the modification of circuit to damaging
The timely substitute and the emergency lock to relay of bad relay, prevent accident, if asking occurs in one of relay
Topic is damaged, and also circuit will not be had any impact, easy to use, flexible and changeable.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
Claims (1)
1. a kind of self-locking and multiple control circuit based on electromagnetic controller, it is characterised in that by connections terminal (1),
