Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments：As shown in Figure 1, Figure 2 with Fig. 3 institutes
A kind of intellectual alarming in short range of electric power device shown, the alarm include shell 1 and the internal structure being arranged in shell 1, the inside
Structure includes whether carrying the double type warning circuit of electric current for sensing apparatus, and the double type warning circuit includes electromagnetic change formula
Warning circuit and curent change formula warning circuit, the electromagnetic change formula warning circuit include the electromagnetism for detecting changes of magnetic field
Formula sensor, the curent change formula warning circuit include the digital display ammeter 2 for detecting curent change, and the electromagnetic type passes
The output terminal of sensor and digital display ammeter 2 is all connected with the input terminal of PLC controller, and the output terminal of the PLC controller connects respectively
Connect phonetic alarm 3 and warning lamp 4.
Electromagnetic change formula warning circuit includes 10, three magnetic induction loops 5 for being connected in 10 both ends of power supply in parallel of power supply, each
Magnetic induction loop 5 is also connected, and there are one resistance 6, and the resistance value of three resistance 6 is different, and there are one branch switches on each parallel circuit
7,10 side of power supply is additionally provided with the first master switch 8, and the electromagnetic sensor is three and is respectively used to detect magnetic strength
Magnetic flux change in coil 5.
Curent change formula warning circuit includes described three magnetic induction loops 5 being arranged in parallel, connects with each magnetic induction loop 5
Resistance 6 and branch switch 7, further include the digital display ammeter 2 of the setting that is in series with three magnetic induction loops being arranged in parallel 5, institute
The side for stating digital display ammeter 2 is equipped with the second master switch 9.
The output terminal of digital display ammeter 2 is connect after D/A converter module with the input terminal of PLC controller.
The number of turn of three magnetic induction loops 5 is identical.
Phonetic alarm 3 and warning lamp 4 are arranged on the shell 1, are additionally provided with to control respectively on the shell 1
Five buttons 11 of three branch switches 7, the first active switch 8 and the second master switch 9.
Can electrical verification be carried out in two ways when in use with Fig. 3 as shown in Figure 1, Figure 2, the first is electromagnetic change formula
Warning circuit, it is existing during use to disconnect the second master switch 9, the first master switch 8 is closed, according to the band for the electrical verification of being carried out
The voltage class of electric equipment and select with which magnetic induction loop 5, the resistance value of resistance 6 connected by three road magnetic induction loops 5
Difference, so different in 10 times passed through electric currents of same power supplies, the magnetic flux by corresponding magnetic induction loop 5 is also different, in this way
The magnetic induction loop 5 of different magnetic flux can be selected to be detected for the charging equipment of voltage levels, charging equipment voltage is high
It is then larger to flux effects, low resistance circuit may be selected, because the low then circuital current of resistance value is big, be unlikely to make magnetic flux moment
Amplification is too big, and charging equipment voltage is low then smaller to flux effects, and high value circuit may be selected, because then circuit is electric for resistance value height
It flows small, even if magnetic flux change is little, is also able to detect that, its is corresponding by lower casing 1 when selecting a certain magnetic induction loop 5
Button 11, then its corresponding branch switch 7 open, it may be used and is detected, if equipment live pass through magnetic induction loop 5
Magnetic flux, it may occur that variation, then PLC controller can be sent a signal to after electromagnetic sensor detects, PLC controller can be controlled
The alarm of phonetic alarm 3 processed and warning lamp 4 flicker.
If selection curent change formula warning circuit is detected, then is then disconnected the first master switch 8, by the second master
Control switch 9 be closed, some magnetic induction loop 5 is selected to be detected, if the larger namely voltage class of charging equipment electric current compared with
Height, then it is larger by the larger namely magnetic flux change of the magnetic flux of magnetic induction loop 5, then the resistance value that resistance 6 may be selected is larger
All the way, the range of digital display ammeter 2 is avoided exceeding, if charging equipment voltage class is relatively low, passes through the magnetic of magnetic induction loop 5
Flux is smaller, and namely magnetic flux change is smaller, then the resistance value that resistance may be selected is smaller all the way, is unlikely in this way because of electricity
Stream is too small and digital display ammeter 2 is made to can't detect weak current.Similarly digital signal is converted into analog signal by digital display ammeter 2
PLC controller is passed to, then the alarm of control voice alarm 3 and warning lamp 4 flicker PLC controller.
The beneficial effects of the present invention are whether the device can carry out detection device in the case where not contacting charging equipment
Electrification, increase safety, and can be detected for different voltage levels values to select different magnetic induction loops, increases
The sensitivity of detection has preferable applicability.
