The effect of Surge suppression.
Description of the drawings
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is that the present invention is a kind of is closed life based on line voltage, switch in silicon-controlled intelligent switch Surge suppression method
Enable the practical closure of line voltage zero passage interrupt signal, relay control signal and relay that signal, computation chip provide
The oscillogram that state changes over time；
Fig. 2 is a kind of structure diagram of intelligent switch Surge suppression system in the present invention.
Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.
A kind of intelligent switch Surge suppression method, includes the following steps：
Step 1, when intelligent switch receives switch control signal, start acquire alternating current zero crossing information, calculate alternating current
First zero crossing arrives the time；Step 2 carrys out interim, closing relay when first zero crossing of alternating current.
Preferably, in the step 1, mode receives switch control signal to the intelligent switch by radio communication.
Preferably, step 2 specifically includes：Reserved relay starts the time, it is ensured that when first zero crossing of alternating current come it is interim,
The contact closure of relay.
As shown in Figure 1, it illustrates line voltage, switch closure command signal, the line voltage mistake that computation chip provides
Zero interrupt signal, relay control signal show the oscillogram that the practical closed state of relay changes over time, and are 1. alternating current electricity
2. corrugating represents switch closure command (coming from wireless communication module), 3. represents the line voltage zero passage that computation chip provides
4. interrupt signal, waveform are relay control signal (high level relay closures), the practical closure of waveform 5. indicating relay
Time (relay disconnects before trip point, is reliably closed after trip point).Intelligent switch captures zero crossing, and root by computation chip
Best close commands generation time T3 is calculated according to the relay response time, ensures that relay practical closing moment is fallen in zero passage
Near point.
When intelligent switch receives at the T1 moment switch command of wireless telecom equipment transmission, computation chip starts to acquire alternating current
Zero passage is interrupted, and first zero crossing arrives at the T2 moment, generates interruption.Relay is closed control command and is generated at the T3 moment, T3
Selection be to be determined according to the response time T of T2 and relay, ensure that relay is fallen in T4~T5 sections.T4, T5 are close to mistake
Zero (zero crossing voltage is zero).According to ohm law it is found that when one timing of load, voltage determines the size of electric current, so as to reach
To the effect of Surge suppression.
