The advantages are that: the user can know the power utilization state and the related trip reasons more conveniently.
Description
Technical Field
The utility model belongs to the low-voltage circuit breaker field, concretely relates to miniature earth leakage protection circuit breaker with voice function.
Background
In order to distinguish the tripping reason, the traditional miniature leakage protection circuit breaker is provided with an leakage tripping indication mark (an indicator light or an indicator key), when the circuit breaker trips, if the indication mark changes the state, the circuit breaker indicates the tripping caused by leakage, and if the indication mark does not change the state, the circuit breaker indicates the tripping caused by overload or short circuit.
However, with the development demand, the protection functions of the miniature earth leakage circuit breaker are more and more, and a plurality of new protection functions are added, such as: the problems of the prior art are that owing trip, overvoltage trip, undervoltage trip, overheating trip and the like exist if the reason of each trip is distinguished according to the traditional method:
1. the number of the indication marks is large, and the indication marks need to be printed, so that the panel area is small and the layout is difficult.
2. The user is inconvenient to observe.
In view of this, the utility model provides a miniature earth leakage protection circuit breaker with voice function when solving above-mentioned problem, can also carry out voice broadcast to other incident.
Disclosure of Invention
In order to solve the above problems, the utility model provides a miniature earth leakage protection circuit breaker with voice function, which comprises a circuit breaker body and a circuit, wherein the circuit comprises a sampling unit, a CPU processing unit and a voice unit;
the sampling unit is connected with the CPU processing unit and provides the acquired data to the CPU processing unit, and the CPU processing unit automatically judges whether a voice broadcast control signal needs to be sent to the voice unit or not according to the data provided by the acquisition unit;
the voice unit is connected with the CPU processing unit, receives a voice broadcast control signal of the CPU processing unit, and broadcasts corresponding voice content.
The voice broadcasting system further comprises a key, wherein the key is connected with the CPU, and the CPU repeatedly sends a voice broadcasting control signal after receiving a key action signal.
Further, the voice unit contain voice chip, speaker, the voice content that needs to report has been preset to the segmentation in the voice chip.
The utility model has the advantages that: the user can know the reason of the trip fault more conveniently.

Detailed Description
The utility model provides a pair of miniature earth leakage protection circuit breaker with voice function refers to fig. 1, contains circuit breaker body 5 and circuit, the circuit has contained sampling unit 1, CPU processing unit 2, button 4, speech unit 3.
Of course, the circuit breaker body contains shell, handle, divide closing mechanism, electronic release, leakage current transformer, bimetallic strip, arc extinguishing bars, electromagnetic release, binding post etc. to realize the function of circuit breaker, if: overcurrent trip protection, earth leakage trip protection, over-under voltage trip protection, etc.
The sampling unit 1 is connected with the CPU processing unit 2, and the sampling unit 1 provides the acquired data to the CPU processing unit 2, such as: current, voltage, temperature, etc.
Specifically, CPU processing unit 2 has preset corresponding judgement logic and procedure, if, has preset the threshold value of corresponding data such as electric current, voltage, temperature at CPU processing unit 2, has surpassed the threshold value of corresponding data when the actual data that sampling unit 1 gathered, whether reunion circuit breaker body trips, if the circuit breaker body has tripped, just carry out voice broadcast processing to corresponding trouble to send voice broadcast control signal for voice unit 3.
Further, after the CPU processing unit 2 receives the action signal of the key 4, the voice broadcast control signal is repeatedly sent. The necessity of such an arrangement lies in: when the circuit breaker is tripped due to faults, a user cannot know the information (if the user goes out) at the first time to a great extent, and at the moment, the user can know the fault information only by operating the key.
Further, referring to fig. 2, the voice unit 3 includes a voice chip 31 and a speaker 32, and voice contents to be broadcasted are preset in the voice chip 31 in segments.
Further, referring to fig. 3, the utility model provides a technique is applicable to the miniature earth leakage protection circuit breaker of three-phase four-wire system equally.
Here, it should be noted that the "voice content to be reported" preset in the voice chip not only is the trip fault information of the miniature earth leakage protector, but also includes the alarm (abnormal condition that is not enough to trigger the miniature earth leakage protector to trip) information during the operation process.
Finally, it is to be noted that: the above description is for the purpose of describing the present invention in further detail with reference to specific preferred embodiments, and it is not to be construed that the embodiments of the present invention are limited thereto, and it will be apparent to those skilled in the art that the present invention is susceptible to various and simple deductions and substitutions, and all such changes and modifications are deemed to fall within the scope of the claims of the present invention.
