Description
Technical field
Electrical part is controlled the present invention relates to one kind, more specifically, it relates to a kind of relay action unit and its relay
Component.
Background technology
Relay（English name：relay）It is a kind of electric control device, is to work as input quantity（Energizing quantity）Change reach rule
During provisioning request, controlled volume is set to occur a kind of electrical equipment of predetermined Spline smoothing in electric output circuit.It has control system
（Also known as input circuit）With by control system（Also known as output loop）Between interactive relationship.It is commonly used to the control of automation
In circuit, it is actually the one kind " automatic switch " for going to control high current running with low current.Therefore play in circuit automatic
Regulation, safeguard protection, change-over circuit etc. are acted on.It includes following structure：Coil holder, armature component, promote piece, splitter and
Coil is arranged with movable contact and at least one stationary contact on splitter, coil holder, coil controls armature group by weak electric signal
Part is acted, and armature component, which drives, promotes piece motion so that movable contact and stationary contact division on splitter.Stationary contact sets still
On, when stationary contact and movable contact contact, division control is realized in still and moving plate conducting.
As intelligent control is applied and is popularized, increasing equipment relies on signal and works and carry out logic judgment, by not
Same algorithm realizes the intelligent control of whole system, and the feedback and acquisition of each device action and working condition are to realize intelligence
The essential important technology of control system, and for adaptive polarizing memory voltage time constant, a most important feedback signal is exactly to represent relay
The status signal of operating state, one, whether can normally be moved according to the multilevel iudge relay of input signal and output signal
Make.Two, can be directly according to the operating state of relay as according to the operation for controlling the relay or other equipment.
At present, the function of relay working state signal feedback is realized, it is technically relatively common to have following several realities
Existing method：
1st, by setting circuit in the outside of relay, whether detection still turns on corresponding moving plate, to judge at present
Actuating of relay state, but this mode, because detected electric current is larger, so need to set strong and weak electric isolating circuit,
And the feedback signal of detection still there may be interference and power consumption, while undoubtedly adding relay user when in use
Design cost.
2nd, sensing element directly is set in movable contact structure（Because moving plate is static, so dynamic touch can only be arranged on
Select or splitter is close to the position of movable contact）, by sense element senses mechanical action, and export electric signal, this output side
Formula, although reduce design cost and not over any other circuit, feedback time is very fast, still, if this position is set
Put one end close to movable contact in splitter, then be equivalent to be arranged on the position collaborated after splitter shunting, herein
Electric current easily disturb, because electromagnetic induction phenomenon produces harmonic current and influences signal to transmit, and sensing element is in itself
Easily by magnetic interference, so this design method does not obtain extraordinary promotion and application yet.
