Description
Technical field
The utility model belongs to electronic technology and electrical technology field, relates to a kind of working state indicator of circuit breaker.
Background technology
(be commonly called as: many advantages are arranged air switch), be widely used at present, it has replaced substantially prolongs the old-fashioned bakelite knife switch of using the sort of band fuse for a long time for single-pole circuit breaker or multipole circuit breaker.But the frosty face of isolating switch in line, its duty is directly perceived inadequately, as: when tripping operation takes place in electricity consumption at night isolating switch or run into situation such as power failure, electricity consumer can't correctly be judged for the moment, particularly consumer is short-circuited after the fault, electricity consumer is got used to blindly closing a floodgate under not clear situation, and the easy like this accident such as fault coverage expansion that causes because of custom or misjudgment takes place.
There is not the deficiency that duty is indicated in order to remedy and to overcome existing isolating switch, be necessary to develop a kind of servicing unit that can indicate working state of circuit breaker, make electricity consumer no matter by day or can both know night the duty of seeing isolating switch be switched on or switched off, whether the isolating switch lead-out terminal have electricity etc., judging line fault character comparatively exactly for electricity consumer provides foundation or reference, avoids electricity consumer because of blindly operating electric shock accidents to take place.
Technology of the present utility model both can be used as the isolating switch servicing unit and had developed separately, also capable of being combinedly carried out supporting exploitation to single-pole circuit breaker or multipole circuit breaker assembly inside.
The utility model content
Goal of the invention and beneficial effect: in order to remedy and overcome the defective of existing single-pole circuit breaker or the no duty indication of multipole circuit breaker existence, by installing the multiple indicating circuit of simple electronics additional, can judge single-pole circuit breaker or the residing duty of multipole circuit breaker fast, fixing a breakdown for electricity consumer provides reference, avoids electricity consumer blindly to operate and accidents such as electric shock take place.Indicating circuit both can also can be used isolating switch with the trendy electrician of its technical research as the update device of normal circuit breaker.
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.
Technical characterictic: working state indicator of circuit breaker, by single-pole circuit breaker and 3 groups of indicating circuits, it is characterized in that: the composition structure of 3 groups of indicating circuits is identical.
The annexation of components and parts in the working state indicator of circuit breaker circuit
The single-pole circuit breaker mode indicator is made up of single-pole circuit breaker and 3 groups of identical indicating circuits of circuit structure.The indicating circuit of working state indicator of circuit breaker is made up of by the highlighted light emitting diode of capacitance decompression, silicon diode rectification, mu balanced circuit, dropping resistor and different colours civil power 220V, its annexation is: the L end of the termination civil power live wire of decompression capacitor C1, the positive pole of another termination silicon rectifier diode D1 of C1, the negative pole of D1 connects the negative pole of voltage stabilizing diode D3 and the end of dropping resistor R1 respectively, the positive pole of another termination red light emitting diodes D2 of R1, the negative pole of D2 and the N end that connects the civil power zero line after the positive pole of D3 links to each other in the lump.
The rule of the components and parts annexation in the other 2 groups of indicating circuits of indicator is same as above.
The upper terminal of single-pole circuit breaker Q connects the L end of civil power live wire and the end of decompression capacitor C1, and the lower terminal of single-pole circuit breaker Q connects the L ' end of consumer.
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 circuit breaker 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 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.
