The utility model can automatically complete the switching tasks under various conditions. The utility model can not only receive the control signal from the program-controlled machine to work but also constitute a logic circuit, edit simple operation sequence, and make one or a plurality of machines automatically work or work in phase. According to requirement, the utility model can be provided with optical control, temperature control, pressure force (piezoelectric) control, voltage control and current control, and the utility model is used for safety production and automatic control. Compared with the similar switch, the utility model has the advantages that the safety, the reliability, the sensitivity and the transmission efficiency of the electrical energy can be enhanced, and the function is expanded.
Description
The utility model belongs to noncontacting switch class field.
Several advanced persons' non-contact switch circuit is consulted China Machine Press's in April, 1986 Beijing front page " electric semiconductor circuit theory " P516 page or leaf " Figure 11-144 " and " Figure 11-146 "; Science Press's in November, 1988 the third printing " electronic circuit encyclopedia " P623 page or leaf " triode ac switch zero voltage switch "; " radio " magazine fifth phase P29 in 1988 page or leaf " application of novel solid-state relay "; Publish second edition " novel bidirectional triode thyristor trigger " " electronics newspaper " on September 11st, 1988; " electronics newspaper bound volume in 1987 " P168 page or leaf " accumulator cell charging and discharging automatic control circuit ".Look into " Chongqing patent place " Chinese patent bulletin, be difficult and this switchtype patent.
More than several circuit and other non-contact switch circuit following shortcoming is arranged respectively: (1) fail safe and poor reliability, especially with exchange (220V) power supply the switch of DC channel arranged; (2) function difference or function singleness, the automatic transfer process that has far need relay to help; (3) range of application is narrow or electric energy transmitting efficient is lower, and the zero-voltage-switch as 1988 10 phase P6 of " CYBERSPACE " magazine page or leaf " controllable silicon zero voltage switching circuit and application " is introduced is unsuitable for big inductive load, and incandescent lamp loads can produce scintillation; " electronics newspaper " second edition on September 11st, 1 " novel bidirectional triode thyristor trigger " circuit, because current-limiting resistance R resistance is big (~220V, MOC3041 get R=330 Ω), certainly lead to phase shift and influence electric energy transmitting efficient, controlled plant power supply accommodation is diminished.
The purpose of this utility model is the function that will enlarge noncontacting switch and improve the performance that exchanges scope solid-state switch (K part).
