Abstract
The utility model discloses the control devices that a kind of relay substitutes contactor, including low-voltage control power, control switch and relay, the relay includes the first relay and the second relay, first relay and the second relay simultaneously concatenate after connecing with described switch, then the positive and negative anodes of low-voltage control power, the first relay and the second relay are connect and draws an electric shock respectively after connecing and is linked into main circuit.The utility model is simple in structure, at low cost；Assembling is easy, efficient；Maintenance cost is low, easy to maintain；Work noise is small；Low-voltage can be utilized to control high voltage, realize remote control, automatically control.
Description
Technical field
The utility model is related to electric switch technical fields, are filled more particularly, to the control that contactor is substituted using relay
It puts.
Background technology
Contactor refers to flow through current induced magnetic field using coil in industrial electro, makes contact closure, loaded with reaching control
Electric appliance, its main application is in main circuit, and during work, electromagnet is powered, and armature, which is inhaled, makes A points and B point contacts, main work
Make closing of circuit；Electromagnet loses magnetism when powering off, and spring handle armature pulls up, and cuts off main operating circuit operating circuit.In reality
Border is big with duration, noise in use, the contactor assembling in some main circuits is relatively difficult, and use cost is high.Relay
And a kind of common electric switch, at low cost with respect to having for contactor, assembling is easy, efficient, easy care, noise
The advantages that small, how to substitute contactor using relay to reach preferable cost performance in actual circuit is the utility model
Purpose.
The content of the invention
The utility model is in view of the above-mentioned problems, provide a kind of control device that contactor is substituted using relay.This practicality
New technical solution is：
A kind of relay substitutes the control device of contactor, described including low-voltage control power, control switch and relay
Relay includes the first relay and the second relay, and the first relay and the second relay simultaneously concatenate after connecing with described switch,
Then the positive and negative anodes of low-voltage control power, the first relay and the second relay are connect and draws an electric shock respectively after connecing and is linked into main electricity
Lu Zhong.
It is further illustrated as the utility model, the voltage of the low-voltage control power is less than the voltage of the main circuit.
Further, the low-voltage control power voltage is DC power supply.
Further, the low-voltage control power voltage is 12V.
Further, the control device is used to substitute the contactor in former main circuit.
Compared with present technology, the utility model such as following advantages:
1st, the utility model design control device it is simple in structure, by two relay Parallel Controls, contact of connecting
Mode changes the contactor control of former main circuit；
2nd, the assembling of control device is easy, efficient, at low cost；
3rd, the maintenance cost of control device is low, easy to maintain；
4th, the work noise of control device is small；
5th, low-voltage can be utilized to control high voltage, realizes remote control, automatically controls.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Specific embodiment
Embodiment：
A kind of relay substitutes the control device of contactor, described including low-voltage control power, control switch and relay
Relay includes the first relay and the second relay, and the first relay and the second relay simultaneously concatenate after connecing with described switch,
Then the positive and negative anodes of low-voltage control power, the first relay and the second relay are connect and draws an electric shock respectively after connecing and is linked into main electricity
Lu Zhong.As shown in Figure 1, the low-voltage control power of the present embodiment is 12V DC power supply, main circuit is 60V DC working circuits, electric
Road load is drawn an electric shock for heater, the first relay and the second relay and after connecing and is concatenated into main circuit respectively, and connect
12V DC control power supply is connected after first relay and the second relay concatenation control switch.During utility model works, it is closed
Control switch, the first relay and the second relay obtain electric, and electromagnet is powered, and armature, which is inhaled, makes A points and B point contacts, leads
Operating circuit, which is closed, to be connected, and load heater, which is powered, starts to work；Control switch is opened, the first relay and the second relay lose
Electricity, electromagnet power-off lose magnetism, and spring handle armature pulls up, and cut off main circuit, and main circuit disconnects, and load heater dead electricity is stopped
Only work.The present embodiment substitutes the contactor in former main circuit by low-voltage control power, control switch and relay assembly, real
Now high voltage, far distance controlled being controlled using low-voltage and being automatically controlled, reaching reduces cost, simplifies assembling, improves efficiency, subtracts
The effect of few noise.
Although more detailed elaboration is done to the technical solution of the utility model and has been enumerated, it should be understood that for
For those skilled in the art, modification is made to above-described embodiment or uses equivalent alternative solution, this skill to this field
Be for art personnel it is clear that on the basis of without departing from the utility model spirit these modifications or improvements, belong to
In the scope of the requires of the utility model protection.
