Description
Technical field
The present invention relates to a kind of electricity protection technologies.
Background technique
Current electricity protection breaker and guard method are all based on the comparator of a preset reference value.Such as volume
Constant current is the breaker of 63A, and when in use, it can compare the size of actual current Yu rated current 63A the moment, when practical electricity
When stream is greater than rated current 63A, breaker will will disconnect circuit, to play the role of protection.But, in construction personnel for certain
When kind reason, the diameter of wire of installation and the rated current of breaker mismatch, breaker will fail.Such as construction personnel's peace
The copper electric wire that diameter is 6 square millimeters has been filled, the breaker of 63A has but been selected, has not just had protective effect.6 square millimeters
Copper electric wire can only safety 48A electric current, deduct poling, enter the factors such as wall, environment temperature, safe current only has 80%, practical electricity
Stream should not be more than 40A, otherwise there is risk on fire.If user has selected the breaker of 63A, that is, cable it is on fire short circuit with
It afterwards just can trip protection.The case where this erroneous matching line footpath is with breaker is much, especially in some unkind buildings
In the engineering of construction team, using inferior materials and turning out substandard goods often will appear: breaker is mounted in switch-box, everybody is observable, is not allowed
Easily play tricks, but electric wire is that poling enters wall installation, everybody is invisible, is just easy to be changed to minor diameter by illegal construction team
Electric wire, in the hope of higher project benefits.
Summary of the invention
Diameter of wire size can be detected and according to diameter of wire size setting safety the purpose of the present invention is to provide a kind of
The electricity protection breaker of protective current.
The invention is realized in this way including microprocessor chip part, the breaker being connected between power supply line and power supply
Partially, the temperature detection part for detecting power supply line temperature, the current detecting part for detecting power lead current, detection power line voltage
Current detection section, the memory of microprocessor chip part have various national standard diameter power supply lines (such as 4 square millimeters or
6 square millimeters of person) at national standard voltage (such as 220V), caused by the electric current that imports various numerical value in the set time period
The data acquisition system of the data set of the changing value of temperature detects the current detecting part institute of power lead current in the set time period

The electronic data of variation, the electronic data for importing electric current, voltage electronic data are spent to be matched with data set in data acquisition system, if
Successful match, then the corresponding national standard diameter power supply line of matched data set be actually use power supply line, it is then, micro-
Processor chips part sets corresponding safeguard protection electric current according to the power supply line diameter information of actual use obtained.
The diameter of wire, real time temperature have directly related mathematical relationship with realtime power, when electric current reaches certain numerical value
When, the temperature of power supply line can be caused to rise, and the rising of temperature be it is related with power supply linear diameter, such as access thousands of watts of electric appliance
When, the temperature of power supply line can increase, and until reaching fever and heat dissipation balancing, and when starting importing high current, temperature rises
Be it will be apparent that and it is mainly related with electric current, power supply linear diameter, voltage, duration, it is true when electric current, voltage, duration
After fixed, power supply linear diameter is determined that, in this way, being just accurately to know power supply line by the relationship between analysis electric current and temperature
Diameter provides possibility, is largely detected at different conditions in advance, and will test what acquired data set was constituted
Data acquisition system is pre-stored in microprocessor chip part, using the method for big data machine learning, utilizes minimal amount of electric current, temperature
Sensor, so that it may by the real time temperature of electric wire, real-time current and between cable rate temperature change when curent change
Relationship, extrapolate the diameter of electric wire, thus automatically be arranged a safeguard protection electric current.It thus can achieve intelligence setting to protect
Protect the function of limit value.Even if user is ignorant of selecting appropriate breaker or is used inferior materials and turned out substandard goods to install wrong breaker, this open circuit
Device can also play the defencive function of Electrical Safety.
Here, it is provided with wireless communication part, data acquired in microprocessor chip part pass through wireless network
Communications portion is transmitted to background server, and background server is also by number acquired in its other electricity protection breaker obtained
According to the electricity protection breaker is transmitted to, to use the method for big data machine learning, Lai Tisheng electricity protection breaker intelligence
Judge the accuracy of power supply linear diameter.
Compared with the prior art, diameter of wire size can be detected and set safety according to the diameter of wire size present invention by having
The advantages of protective current.
