Technical scheme: install the multiple indicating circuit of electronics of little power consumption in single-pole circuit breaker or multipole circuit breaker additional, indicating circuit is made up of by the highlighted light emitting diode of capacitance decompression, silicon diode rectification, mu balanced circuit and different colours civil power.By the bright of 3 light emitting diodes and the various combination that does not work, can judge the nature of trouble of line.
Description of drawings
Accompanying drawing is a working state indicator of circuit breaker circuit working schematic diagram.
Circuit in the accompanying drawing is made up of 3 groups of identical in structure indicating circuits, and the requirement of every group of indicating circuit component parameter is also basic identical; Q is a single-pole circuit breaker, is called for short: isolating switch; RL is a consumer.
Embodiment
Accompanying drawing and description of drawings are that example is further described correlation technique of the present invention with single-pole circuit breaker (single-phase 220V alternating current) mode indicator below to specifications.
Circuit is formed: working state indicator of circuit breaker is made up of single-pole circuit breaker and 3 groups of identical in structure indicating circuits.The indicating circuit of single-pole circuit breaker mode indicator is made up of by the highlighted light emitting diode of capacitance decompression current limliting, silicon rectifier diode rectification, mu balanced circuit and different colours civil power 220V alternating current.
Principle of work: when the line normal power supply, the indicating circuit of single-pole circuit breaker obtains 5V stable DC voltage by civil power by decompression capacitor C1, silicon diode D1 rectification, voltage stabilizing diode D3, utilize resistance R 1 current-limiting points shiny red light emitting diode D2, in like manner green LED D9 is also lighted luminous.It is because two connection terminals up and down of isolating switch (Q) are in on-state that yellow light-emitting diode D6 does not work, the event of no-voltage difference between the L end of civil power live wire and the L ' end;
When the isolating switch generation that is connected between the L of civil power live wire end and the L ' end is tripped (disconnection), red light emitting diodes D2 keeps lighting, green LED D9 extinguishes, yellow light-emitting diode D6 forms the loop by consumer (RL) and civil power working zero line N and is lighted, and this shows with electric line and overloads or consumer fault such as be short-circuited;
After night, isolating switch tripped, the low-light that light emitting diode D2, D6 send can be used as the temporary lighting of panel box, and electricity consumer can be checked the processing circuitry fault by low-light, and the power consumption during indicating circuit work is very little, can ignore substantially.In order to solve light emitting diode operating voltage deficiency, cause the not enough problem of light-emitting diodes brightness, special in the circuit for the light emitting diode reliably working has designed stabilized voltage supply, and the light emitting diode of brightness or superbright degree is used in selection.Voltage stabilizing diode has access to two effects: the one, and for light emitting diode provides working power, the 2nd, guarantee that light emitting diode is not punctured by the civil power reverse voltage.
When civil power took place to have a power failure, the isolating switch that connects can not trip between the L of civil power live wire end and the L ' end, and 3 light emitting diodes (D2, D6, D9) on the isolating switch circuit all extinguish.Electricity consumer according to light emitting diode D2, D6, D9 is bright and the various combination that do not work, can roughly judge the character of line fault.
