Detailed description of the invention:
Fig. 1 is circuit diagram of the invention.
Specific embodiment:
Present invention will be further explained below with reference to the attached drawings and specific embodiments:
A kind of processing method reducing the nigrescence carbonization of timer contact, includes the following steps, the first step, in load and timing
Series connection delay output control circuit between device, as shown in Figure 1, delay output control circuit includes by first resistor R1, the second electricity
A delay turn-on circuit of R2, diode D1, capacitor C1, voltage-stabiliser tube Z1 and relay RY1 composition are hindered, wherein first resistor
R1, second resistance R2 and diode D1 are in parallel with capacitor C1, voltage-stabiliser tube Z1 and relay RY1 after connecting, and further include 3rd resistor
R3 and the 4th resistance R4,3rd resistor R3 and the 4th resistance R4 are connected in parallel between output terminal and input terminal, in relay RY1
When actuation, by 3rd resistor R3 and the 4th resistance R4 powering load, relay after relay RY1 is attracted
The contact RY1 and 3rd resistor R3 and the 4th resistance R4 short circuit, high current are passed through from the contact relay RY1, and ACN terminal is timer
Power supply common end, wherein capacitor C1 be electrolytic capacitor.Visible Fig. 1 of design parameter in circuit；
Second step after timer output, first passes through the 3rd R3 and the 4th R4 powering load on delay plate, by above-mentioned
The effect of two resistance is so that timer is not up to rated power, and immediate current is also smaller (if power supply is AC220V/ at this time
50Hz, resistive load are 1000W, then powered on moment electric current does not exceed 4.5 amperes), effectively reduce the contact of timer contact
The electric current of moment, reduce timer to the interference of power grid, prevent contact to be sintered and reduce contact carbonization probability；
Third step, while 3rd resistor R3 and the 4th resistance R4 powers to timer, also by first resistor R1, the
Two resistance R2 and diode D1 charge to capacitor C1, when the voltage at the both ends capacitor C1 reaches the pick-up voltage of relay, relay
Device is attracted, and due to there is voltage-stabiliser tube Z1 to be connected in parallel on capacitor and relay both ends, so voltage will not rise always, but is stablized steady
The clamp voltage of pressure pipe is so that will not puncture capacitor C1 and burn out relay RY1.The contact of mechanical timer has been at the same time
Through contacting securely, maximum contact contact area is reached；It inhales contact after relay RY1 is attracted inside 3,4 feet of relay
It closes 3rd resistor R3 and the 4th resistance R4 short circuit, prevents 3rd resistor R3 and the 4th resistance R4 from passing through high current for a long time hot
It burns out, at this time since 3rd resistor R3 concatenated in load circuit and the 4th resistance R4 are shorted, so timer will enter
It works under normal power rating.
The present invention is by concatenation output delay control circuit, using the resistance in time delay resistance value to the voltage between contact
Contacted after being depressured, reduce because high voltage exist due to be electrically conductive forming under-stream period arc stiffness, reduction contact carbonization probability,
Increase contact service life, improves the reliability of timer.
Only the preferred embodiment of the present invention has been described above, but is not to be construed as limiting the scope of the invention.It is all
It is the equivalent structure or equivalent flow shift done using description of the invention and accompanying drawing content, is included in patent of the invention
Within protection scope.
