Embodiment
According to accompanying drawing, the present invention is described in further detail below:
As shown in Figure 1, dynamic STS reactive compensation switching adjuster, mainly comprise a control chip, the input of this control chip exports switching signal after connecting the signal of sample circuit, voltage transformation module, control signal input circuit, control chip process sample circuit, voltage transformation module, control signal input circuit and carries out switching action to thyristor gating circuit.And radiating module its form primarily of radiator, radiator fan and a temperature collect module; Temperature collect module gathers the temperature signal input control chip of radiator, and control chip treatment temperature signal outputs signal to the work that radiator fan controls radiator fan.
Control chip also connects indicator light, control chip export switching signal to trigger module and output signal to indicator light display.Control chip also connects a protection module, and this protection module exports the input of control guard signal to control chip after gathering the gentle default phase signal of mistake of control chip, control the switching work of control chip.
Wherein sample circuit is by three-phase electricity by magnetic bead High frequency filter, and after electric resistance partial pressure, through the zero crossing of the electric wherein two-phase of two Light Coupled Device sampling three-phases, the crossover point signal of electrical network adjusts through trigger, as input signal input control chip.
Thyristor gating circuit is three road thyristor gating circuits, and each route two triggers optocoupler series connection at the two ends of silicon controlled module, drives inverse parallel silicon controlled module when triggering optocoupler and receiving the switching signal that control chip sends.
Power supply input 380V, export the switching power circuit of two-way+12V and+5V, its circuit realizes primarily of an Infineon ICE3B0565 metal-oxide-semiconductor of connecting, and wherein+12V powers to fan, and+5V powers to control circuit simultaneously.
As shown in Figure 2: during work, first control chip collecting temperature signal, when temperature is lower than 45 degrees Celsius, direct collection voltage zero-crossing signal, judge voltage whether phase shortage simultaneously, when voltage not phase shortage time judge whether to need switching action, if need switching, send triggering signal to controlling switching action.
When temperature starts fan higher than when 45 degrees Celsius, simultaneously collecting temperature signal again, when temperature is higher than 45 degrees Celsius, reports to the police and excises triggering signal.
Simultaneously when the voltage zero-crossing signal phase shortage alarm prompting collected, and return beginning.
The present invention its can be applicable to the switching of all kinds of capacitor; And there is the advantage such as fast response time, the dynamic switched capacitor without overvoltage, no-flashy-flow, more convenient bring to use.
