Mutual inductor polarity descriminator split type to the present invention is described in further detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention split type mutual inductor polarity descriminator.
Fig. 2 is the present invention split type mutual inductor polarity descriminator fundamental diagram.
Detailed description of the invention
As Figure 1-Figure 2:
A kind of split type mutual inductor polarity descriminator, including hand transmitting equipment 1, hand-held reception equipment 2, described hand transmitting equipment 1 includes launching housing 11, signal generator 12, power amplifier 13, first power supply, launch wire for two, launch wire one end for every and be fixedly connected with conductor clamps, it is provided with signal generator 12 in launching housing 11, power amplifier 13, first power supply, signal generator 12, power amplifier 13 is connected with the first power supply respectively, signal generator 12 is connected with power amplifier 13, launch the wire other end for every to be connected with power amplifier 13；Described hand-held reception equipment 2 includes receiving housing 21, signal discriminator 22, signal amplifier 23, second source, two reception wires, every receives wire one end and is fixedly connected with conductor clamps, it is provided with signal discriminator 22, signal amplifier 23, second source in receiving housing 21, signal discriminator 22, signal amplifier 23 are connected with second source respectively, every receives the wire other end and is connected with signal amplifier 23, and signal amplifier 23 is connected with signal discriminator 22.
Described transmitting housing 11 is externally provided with the first on and off switch 14, controls hand transmitting equipment 1 and switchs, and is provided with triggering call button switch 15, controls to trigger the transmitting situation of signal.
Described signal generator 12 uses pulse signal generator, pulse signal to be easily authenticated.
Described reception housing 21 is externally provided with second source switch 24 and two light emitting diodes 25, an employing green light, and one uses red light, and red light represents positive pole, and green light represents negative pole, and convenient and practical personnel intuitively observe.
The operation principle of the present invention split type mutual inductor polarity descriminator:
Hand transmitting equipment 1 and hand-held reception equipment 2 are connected with transformer 3 respectively, open hand transmitting equipment 1 and hand-held reception equipment 2, when the pulse signal that when call button switchs 15, hand transmitting equipment 1 sends that triggers pressing hand transmitting equipment 1 is added to the once end of tested transformer 3.According to electromagnetic induction principle, transformer 3 secondary side necessarily induces the signal as primary side, and now the induced signal of transformer 3 two times is by the wire being connected with secondary terminals, flows to hand-held reception equipment 2, hand-held reception equipment 2, through judging, demonstrates the true polarity of transformer 3.
