It basically replaces the old-fashioned electric wood switch with fuse that has been used for a long time. But in the cold face of the circuit breaker in the mains line, its working status is not intuitive enough. For example, when the power circuit breaker trips at night or encounters a power outage, the power user cannot make a correct judgment for a while, especially for the power equipment. After a short-circuit fault occurs, power users are accustomed to closing the switch blindly under unknown circumstances, which is easy to cause accidents such as expansion of the fault range due to habit or wrong judgment.

In order to make up for and overcome the lack of no indication of the working state of the existing circuit breaker, it is necessary to develop an auxiliary device that can indicate the working state of the circuit breaker. On or off, whether there is power at the output terminal of the circuit breaker, etc., provide a basis or reference for the power user to judge the nature of the line fault more accurately, and avoid electric shock accidents due to blind operation by the power user.
本发明的技术既可作为断路器辅助装置进行单独开发，也可组合到单极断路器或多极断路器总成内部进行配套开发。The technology of the present invention can be independently developed as an auxiliary device of a circuit breaker, and can also be combined into a single-pole circuit breaker or a multi-pole circuit breaker assembly for supporting development.

The circuit in the attached drawing is composed of 3 groups of indicating circuits with the same structure, and the requirements of parameters of each indicating circuit components are basically the same; Q is a single-pole circuit breaker, Abbreviation: circuit breaker; RL is electrical equipment.
具体实施方式Detailed ways
按照说明书附图和附图说明，下面以单极断路器(单相220V交流电)工作状态指示器为例对本发明的相关技术作进一步的描述。According to the accompanying drawings and descriptions of the drawings, the related technology of the present invention will be further described below by taking the working state indicator of a single-pole circuit breaker (single-
工作原理：当市电线路正常供电时，单极断路器的指示电路由市电通过降压电容C1、硅二极管D1整流、稳压二极管D3得到5V稳定直流电压，利用电阻R1限流点亮红色发光二极管D2，同理绿色发光二极管D9也被点亮发光。黄色发光二极管D6不亮是因为断路器(Q)的上下两个接线端子处于接通状态，市电火的线端L与用电设备端L′之间无电压差之故；Working principle: When the mains line is normally powered, the indicator circuit of the single-pole circuit breaker is 5V stable DC voltage obtained by the mains through step-down capacitor C1, silicon diode D1 rectification, and Zener diode D3, and the red light is lit by resistor R1 current limiting The light-emitting diode D2 and the green light-emitting diode D9 are also turned on to emit light. The reason why the yellow light-emitting diode D6 is off is that the upper and lower terminals of the circuit breaker (Q) are in the connected state, and there is no voltage difference between the terminal L of the mains fire and the terminal L' of the electrical equipment;
当市电火的线端L与用电设备端L′之间连接的断路器发生跳闸时(断开)，红色发光二极管D2保持点亮，绿色发光二极管D9熄灭，黄色发光二极管D6通过用电设备RL与市电的零线端N形成回路而被点亮，这表明用电线路超过负荷或者用电设备发生短路等故障；When the circuit breaker connected between the line terminal L of the mains fire and the electrical equipment terminal L′ trips (disconnects), the red light-emitting diode D2 remains on, the green light-emitting diode D9 goes out, and the yellow light-emitting diode D6 passes through the power supply. The device RL and the neutral terminal N of the mains power supply are turned on by forming a loop, which indicates that the power line is overloaded or the power consumption device is short-circuited or other faults;
在夜晚断路器发生跳闸后，发光二极管D2、D6发出的微光可作为配电箱的临时照明，用电户可以借助微光查看处理线路故障，指示电路工作时的耗电甚微，基本可以忽略。为了解决发光二极管工作电压不足，导致发光二极亮度不够的问题，电路中专门为发光二极管可靠工作设计了稳压电源，并且选择使用亮度或超亮度的发光二极管。稳压二极管接入有两个作用：一是为发光二极管提供工作电源，二是保证发光二极管不被市电反向电压击穿。After the circuit breaker trips at night, the low light emitted by the light-emitting diodes D2 and D6 can be used as temporary lighting for the distribution box. Power users can use the low light to check and deal with line faults, indicating that the power consumption of the circuit is very small when it is working, and it can basically be used. neglect. In order to solve the problem of insufficient light-emitting diode working voltage and insufficient brightness of light-emitting diodes, a regulated power supply is specially designed for the reliable operation of light-emitting diodes in the circuit, and light-emitting diodes with brightness or super brightness are selected. The connection of the Zener diode has two functions: one is to provide working power for the light-emitting diode, and the other is to ensure that the light-emitting diode is not broken down by the reverse voltage of the mains.
当市电发生停电时，市电的火线端L与用电设备端L′之间所接断路器不会跳闸，断路器线路上的3只发光二极管D2、D6、D9全部熄灭。用电户根据发光二极管D2、D6、D9亮与不亮的不同组合，可以大致判断市电线路故障的性质。When the mains power fails, the circuit breaker connected between the live wire terminal L of the mains power supply and the electrical equipment terminal L' will not trip, and the three light-emitting diodes D2, D6, and D9 on the circuit breaker line are all extinguished. According to the different combinations of light-emitting diodes D2, D6, D9 on and off, the user can roughly judge the nature of the mains line fault.
元器件选择：Component selection:
C1、C2、C3为降压电容，选用0.39～0.47μF/400V的涤纶电容器；C1, C2, and C3 are step-down capacitors, and polyester capacitors of 0.39～0.47μF/400V are selected;
D1、D5、D7为硅整流二极管，型号为：1N4007；D1, D5, D7 are silicon rectifier diodes, model: 1N4007;
R1、R2、R3为限流电阻，选用1/4W～1/8W金属膜电阻或碳膜电阻，阻值为：300～430Ω；R1, R2, R3 are current limiting resistors, choose 1/4W～1/8W metal film resistors or carbon film resistors, the resistance value is: 300～430Ω;
D3、D4、D8为硅稳压二极管，稳压值为5V，稳压管的型号不限；D3, D4, and D8 are silicon Zener diodes, the voltage regulator value is 5V, and the model of the Zener tube is not limited;
D2、D6、D9选用高亮或超亮度发光二极管，3只发光二极管的直径为：￠5mm，3只发光二极管的颜色分别是D2为红色、D6为黄色、D9为绿色。D2, D6, and D9 use high-brightness or super-brightness light-emitting diodes. The diameter of the three light-emitting diodes is: ￠5mm. The colors of the three light-emitting diodes are red for D2, yellow for D6, and green for D9.
电路调试：因单极断路器上的指示电路的结构比较简单，只要元器件接线连接正确，指示电路无需调试即可工作。若需要进一步提高某组发光二极管的亮度，可以适当减小发光二极管相应的限流电阻R1或R2或R3的阻值。调试发光二极管亮度的一般要求：黄色发光二极管D6的亮度最亮，绿色发光二极管D9的亮度次之，红色发光二极管D2的亮度最暗。Circuit debugging: Because the structure of the indicating circuit on the single-pole circuit breaker is relatively simple, as long as the components are connected correctly, the indicating circuit can work without debugging. If the brightness of a certain group of light-emitting diodes needs to be further improved, the resistance value of the corresponding current-limiting resistor R1 or R2 or R3 of the light-emitting diodes can be appropriately reduced. General requirements for adjusting the brightness of LEDs: the brightness of the yellow LED D6 is the brightest, followed by the brightness of the green LED D9, and the brightness of the red LED D2 is the darkest.
注意：若本发明的技术方案使用在多级断路器(三相220V交流电)上，指示电路的结构不变，只是要分别重新调整3组指示电路中的降压电容、降压电阻等参数。Note: if the technical solution of the present invention is used on a multi-stage circuit breaker (three-
