Description
Technical field
The utility model relates to power transmission and distribution and arranges detection technique field, particularly relates to a kind of mutual inductor polarity somascope.
Background technology
At present, when the power transmission and distribution equipment of powering is installed, often need to use mutual inductor, because mutual inductor exists polarity, by estimating the polarity being difficult to determine detected mutual inductor, once uncertain for polarity mutual inductor is arranged on the power transmission and distribution equipment of power supply, to bring hidden danger to power transmission and distribution equipment, when the polarity of mutual inductor is incorrect, the work about electric power personnel of power supply department need to reinstall mutual inductor, time-consuming, cause inefficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of mutual inductor polarity somascope.
For achieving the above object, the utility model is by the following technical solutions:
A kind of mutual inductor polarity somascope, comprising: detect power supply, power switch, detector switch, slide rheostat, multiple binding post and milliammeter; One end of described detection power supply is connected with the first binding post by detector switch, and the other end of power supply is connected with the second binding post by power switch, and the first described binding post and the second binding post are connected to the two ends of the primary side of detected mutual inductor; Described milliammeter and slide rheostat are connected into the polarity display device of range of adjustment, and one end of polarity display device is connected with the 3rd binding post, and the other end of polarity display device is connected with the 4th binding post; The 3rd described binding post and the 4th binding post are connected to the two ends of the secondary side of detected mutual inductor.
Owing to adopting technical scheme as above, the utility model has the following advantages:
A kind of mutual inductor polarity somascope, adopts detection power supply, power switch, detector switch to provide power supply to the two ends of the primary side of detected mutual inductor; The voltage of the secondary side two ends induction of detected mutual inductor shows the polarity of mutual inductor by the polarity display device being connected into range of adjustment by milliammeter and slide rheostat; Namely judge that the polarity of mutual inductor connects fast by the deflection of the indicator of milliammeter, have that Detection accuracy is high, circuit simply, work efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is the circuit diagram block scheme of mutual inductor polarity somascope.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail,
As shown in Figure 1, a kind of mutual inductor polarity somascope, comprising: detect power supply, power switch, detector switch, slide rheostat, multiple binding post and milliammeter; One end of described detection power supply is connected with the first binding post by detector switch, and the other end of power supply is connected with the second binding post by power switch, and the first described binding post and the second binding post are connected to the two ends of the primary side of detected mutual inductor; Described milliammeter and slide rheostat are connected into the polarity display device of range of adjustment, and one end of polarity display device is connected with the 3rd binding post, and the other end of polarity display device is connected with the 4th binding post; The 3rd described binding post and the 4th binding post are connected to the two ends of the secondary side of detected mutual inductor.
The utility model provides power supply by detection power supply, power switch, detector switch to the two ends of the primary side of detected mutual inductor; The voltage of the secondary side two ends induction of detected mutual inductor shows the polarity of mutual inductor by the polarity display device being connected into range of adjustment by milliammeter and slide rheostat; Namely judge that the polarity of mutual inductor connects fast by the deflection of the indicator of milliammeter, have that Detection accuracy is high, circuit simply, work efficiency advantages of higher.
