Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：As shown in Figure 1, Figure 2 with Fig. 3 institute
A kind of intellectual alarming in short range of electric power device showing, this alarm includes shell 1 and the internal structure being arranged in shell 1, described inside
Structure includes whether carrying the double type warning circuit of electric current for sensing apparatus, and described double type warning circuit includes electromagnetic change formula
Warning circuit and curent change formula warning circuit, described electromagnetic change formula warning circuit includes the electromagnetism for detecting changes of magnetic field
Formula sensor, described curent change formula warning circuit includes the digital display ammeter 2 for detecting curent change, and described electromagnetic type passes
The outfan of sensor and digital display ammeter 2 is all connected with the input of PLC, and the outfan of described PLC connects respectively
Connect phonetic alarm 3 and warning lamp 4.
Electromagnetic change formula warning circuit includes 10, three magnetic induction loops 5 being connected in power supply 10 two ends in parallel of power supply, each
Magnetic induction loop 5 is also in series with a resistance 6, and the resistance of three resistance 6 is different, and each parallel circuit also has a branch switch
7, described power supply 10 side is additionally provided with the first master switch 8, and described electromagnetic sensor is three and is respectively used to detect magnetic strength
Magnetic flux change in coil 5.
Curent change formula warning circuit is included described three magnetic induction loops being arranged in parallel 5 and is connected with each magnetic induction loop 5
Resistance 6 and branch switch 7, the magnetic induction loop 5 also including being arranged in parallel with three is in series the digital display ammeter 2 of setting, institute
The side stating digital display ammeter 2 is provided with the second master switch 9.
The outfan of digital display ammeter 2 is connected with the input of PLC after D/A converter module.
The number of turn of three magnetic induction loops 5 is identical.
Phonetic alarm 3 and warning lamp 4 are arranged on described shell 1, and described shell 1 is additionally provided with for controlling respectively
Five buttons 11 of three branch switches 7, the first active switch 8 and the second master switch 9.
Electrical verification can be carried out with Fig. 3 in two ways when in use as shown in Figure 1, Figure 2, the first is electromagnetic change formula
Second master switch 9 is now disconnected during use, the first master switch 8 is closed, according to the band of electrical verification to be carried out by warning circuit
The electric pressure of electric equipment and select with which magnetic induction loop 5, by the resistance of the resistance 6 that three road magnetic induction loops 5 are connected
Difference, thus different in 10 times passed through electric currents of same power supplies, also different through the magnetic flux of corresponding magnetic induction loop 5, so
The charging equipment of voltage levels can be directed to and select the magnetic induction loop 5 of different magnetic flux to be detected, charging equipment voltage is high
Then larger to flux effects, optional low resistance circuit, because the low then circuital current of resistance is big, it is unlikely to make magnetic flux moment
Amplification is too big, and charging equipment voltage is low then less to flux effects, optional high value circuit, because resistance height then circuit electricity
Stream is little, though magnetic flux change little it is also possible to detect, press on lower casing 1 it when selecting a certain magnetic induction loop 5 corresponding
Button 11, then its corresponding branch switch 7 open, then can be detected using it, if equipment live, through magnetic induction loop 5
Magnetic flux it may occur that change, then can be signaled to PLC after electromagnetic sensor detects, PLC can be controlled
Phonetic alarm 3 processed is reported to the police and warning lamp 4 flashes.
If selecting curent change formula warning circuit to be detected, then then to disconnect the first master switch 8, main by second
Control switch 9 closure, selects some magnetic induction loop 5 to be detected, if the larger namely electric pressure of charging equipment electric current is relatively
Height, then the larger namely magnetic flux change of magnetic flux passing through magnetic induction loop 5 is larger, then the resistance of optional resistance 6 is larger
A road, it is to avoid exceed the range of digital display ammeter 2, if charging equipment electric pressure is relatively low, by the magnetic of magnetic induction loop 5
The less namely magnetic flux change of flux is less, then the less road of resistance of optional resistance, is so unlikely to because electricity
Flow too little and make digital display ammeter 2 can't detect weak current.Digital signal is converted into analogue signal by digital display ammeter 2 in the same manner
Pass to PLC, PLC then report to the police and warning lamp 4 flashes by control voice alarm 3.
The beneficial effects of the present invention is, whether this device can carry out testing equipment in the case of not contacting charging equipment
Powered, increased safety, and can increased for different voltage levels values to select different magnetic induction loops to detect
The sensitivity of detection, has the preferable suitability.
