Description of drawings
Accompanying drawing is working state indicator of circuit breaker circuit working schematic diagram, and the circuit in accompanying drawing is comprised of 3 groups of identical indicating circuits of structure, and the requirement of every group of indicating circuit component parameter is also basic identical; Q is single-pole circuit breaker, is called for short: isolating switch; RL is consumer.
Embodiment
Accompanying drawing and description of drawings to specifications, the below is further described correlation technique of the present invention as an example of single-pole circuit breaker (single-phase 220V alternating current) mode indicator example.
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 also is lit 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 poor event of no-voltage between the line end L of civil power fire and consumer end L ';
When tripping operation occurs in the isolating switch that is connected between the line end L of civil power fire and consumer end L ' (disconnection), red light emitting diodes D2 keeps lighting, green LED D9 extinguishes, the zero line side N of yellow light-emitting diode D6 by consumer RL and civil power forms the loop and is lit, and this shows with electric line and overloads or the 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, substantially can ignore.Not enough in order to solve the light emitting diode operating voltage, cause the inadequate problem of light-emitting diodes brightness, special in the light emitting diode reliably working has designed stabilized voltage supply in circuit, and the light emitting diode of choice for use brightness or ultra-brightness.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 occured to have a power failure, between the live wire end L of civil power and consumer end L ', the isolating switch that connects can not trip, and 3 light emitting diode 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.
Components and parts are selected:
C1, C2, C3 are decompression capacitor, select the dacron terylene condenser of 0.39～0.47 μ F/400V;
D1, D5, D7 are silicon rectifier diode, and model is: 1N4007;
R1, R2, R3 are current-limiting resistance, select 1/4W～1/8W metalfilmresistor or carbon resister, and resistance is: 300～430 Ω;
D3, D4, D8 are silicon voltage regulator diode, and the voltage stabilizing value is 5V, and the model of stabilivolt is not limit;
D2, D6, D9 select highlighted or the ultra-brightness light emitting diode, and the diameter of 3 light emitting diodes is: ￠ 5mm, the color of 3 light emitting diodes is respectively that D2 is that redness, D6 are green for yellow, D9.
Circuit debugging: relatively simple for structure because of the indicating circuit on single-pole circuit breaker, correct as long as the components and parts wiring connects, indicating circuit need not debugging and gets final product work.If need further to improve the brightness of certain group light emitting diode, can suitably reduce the resistance of the corresponding current-limiting resistance R1 of light emitting diode or R2 or R3.The General Requirements of debugging light-emitting diode luminance: the brightness of yellow light-emitting diode D6 is the brightest, and the brightness of green LED D9 is taken second place, and the brightness of red light emitting diodes D2 is the darkest.
Attention: if technical scheme of the present invention is used on multistage isolating switch (three-phase 220V alternating current), the structure of indicating circuit is constant, just will readjust respectively 3 groups of parameters such as the decompression capacitor, dropping resistor in indicating circuit.
