The utility model mainly has following technical characterstic:
1, operating passing zero
The basic functional principle of capacitance compensation numerical control switching device is with reverse-blocking tetrode thyristor and common contactor and connects, and by mcu programming, carries out program work, realizes that reverse-blocking tetrode thyristor cuts off in voltage zero-cross conducting and electric current limit zero.Contactor then follows up after the controllable silicon conducting, and the work after the alternative controllable silicon conducting allows controllable silicon back off, controllable silicon moment work is not generated heat, do not produce harmonic wave, and when needs switch disconnection, controllable silicon sends the excision program singal by single-chip microcomputer, controllable silicon Q1 conducting once more, red light D3 is bright, after 0.2S～0.5S time-delay, A.C. contactor turn-offs, green light D4 puts out, and silicon control zero-cross disconnects behind time-delay 0.2S～05.S, thereby realizes the current over-zero excision.
2, no harmonic wave injects
Because controllable silicon conducting moment work, the contactor adhesive conducting of zero cross fired time-delay back does not produce spark, can not produce harmonic wave, and controllable silicon is deactivated, and also can not produce heat.Thereby, so just need not outer radiation fin or fan, reduced cost, thoroughly avoided silicon controlled to burn phenomenon, also to not working the mischief, really reached energy saving purposes simultaneously, improved the life-span of capacitance compensation switching device shifter and the useful life of compensation condenser greatly with other electrical equipment that advances operation, be 10～15 times of original capacitance compensation switching device shifter useful life more than 100,000 times.

One-chip computer module is accepted control signal input, detection, computing, establishment, earlier by controllable silicon with the electric capacity input compensation, red light puts out, continuation is by the A.C. contactor adhesive, green light is bright, and after 0.2～0.5S time-delay, controllable silicon is out of service again, red light puts out, and continues to keep electric capacity to devote oneself to work by A.C. contactor.When control signal required electric capacity to withdraw from compensation, controllable silicon sent the excision program by one-chip computer module, and controllable silicon is conducting once more, and red light is bright, A.C. contactor and disconnected after 0.2～0.5S time-delay, and green light puts out; Controllable silicon turn-offs behind time-delay 02～05S, and red light puts out, and makes the building-out capacitor excision, withdraws from compensation.
Adopt the digital control technology of the little processing of single-chip microcomputer, utilization bidirectional triode thyristor element and combinations such as relevant electronic component, integrated package and contactor, make the capacitance compensation switching along with the signal conveys single-chip microcomputer, just follow procedure carries out reliable, reliable zero passage input compensation, and the conversion contactor does not have harmonic operation; Controllable silicon is out of service, and no harmonic wave produces.When the excision signal arrives one-chip computer module, drop into again by the module instruction controllable silicon, contactor is out of service, and silicon control zero-cross disconnects behind 0.2S～0.5S, thereby realizes the current over-zero excision.So not only prolong the life-span of contactor but also also increased life of capacitors simultaneously.
