Dress or overhaul replaced mutual inductor after to carry out transducer check, test its it is polar configuration it is whether correct, if polar configurations are wrong
Protective device malfunction or the harm of refused action will accidentally be caused；If tripping will cause tripping of bypassing the immediate leadership, malfunction to cause mistakenly stop electricity
Serious consequence.
Currently, current transformer and the traditional polarity method of voltage transformer are to use battery pack, pointer milivoltmeter into
Row direct current measurement, survey tool are loose mail, and when carrying is easy to omit and lose, and usually more than two people operates, needs tacit agreement
Personnel cooperation carry out the work, human factor is excessive during the test, operation it is cumbersome；And mutual inductor pole in the market
Property tester, merged mostly mutual inductor ratio test etc. multiple functions, equipment instrument it is big, quality weight is not portable, into
It is not suitable in the single polarity test course of work of row.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of simple in structure, easy to carry and night time operation, behaviour
Make simple, the simple mutual inductor polarity testing tool of raising on-the-spot test efficiency.
To solve the above problems, a kind of simple mutual inductor polarity testing tool described in the utility model, including test board
Face, it is characterised in that：The test plate face is provided with LED light close to upper side edge or so is corresponding, which connects LED switch；
The test plate face middle position is respectively arranged with primary connection terminal and secondary wiring terminals, below the secondary wiring terminals
It is equipped with equipment charge mouth, charge power supply and dry cell successively；The charge power supply right side side is equipped with earth leakage protective device and power supply is opened
It closes, left side side is equipped with pointer multimeter, and operation plug-in strip is connected with above the pointer multimeter；The charge power supply and dry
Respectively the earth leakage protective device, primary connection terminal, secondary wiring terminals connect power supply with LED light after cell parallel.
The primary connection terminal is divided into high-pressure side L1 and high-pressure side L2.
The secondary wiring terminals are divided into low-pressure end K1 and low-pressure end K2.
The equipment charge mouth is connect with the charge power supply.
Compared with prior art, the utility model has the following advantages：
（1）The utility model keeps its simple in structure due to combination installation test power supply used and instrument in test plate face
It is easy to carry.
（2）The utility model setting LED light in test plate face is illuminated, and night time operation is made it easy to.
（3）Charge power supply and dry cell two ways power supply of the utility model due to using direct current, utilize operation plug-in strip
The power supply of test equipment is connected, traditional human factor is removed, keeps its easy to operate, improve on-the-spot test efficiency.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the wiring diagram of the utility model.
In figure：1. testing plate face, 2.LED lamps, 3.LED switches, 4. primary connection terminals, 5. secondary wiring terminals, 6. set
Standby charge port, 7. charge power supplies, 8. dry cells, 9. earth leakage protective devices, 10. power switches, 11. pointer multimeters, 12. operations
Plug-in strip.
Specific implementation mode
With reference to the accompanying drawings shown in 1,2, a kind of simple mutual inductor polarity testing tool, including test plate face 1, test plate face 1 are leaned on
Nearly upper side edge or so is corresponding to be provided with LED light 2, which connects LED switch 3；Test 1 middle position of plate face is set respectively
It is equipped with primary connection terminal 4 and secondary wiring terminals 5, which divides for high-pressure side L1 and high-pressure side L2, secondary to connect
Line terminals 5 are divided for low-pressure end K1 and low-pressure end K2；5 lower section of secondary wiring terminals is equipped with equipment charge mouth 6, charge power supply 7 successively
With dry cell 8, which connect with charge power supply 7；7 right side side of charge power supply is equipped with earth leakage protective device 9 and power supply is opened
10 are closed, left side side is equipped with pointer multimeter 11, which is connected with operation plug-in strip 12；Charge power supply
7 and 8 parallel connection of dry cell after be respectively earth leakage protective device 9, primary connection terminal 4, secondary wiring terminals 5 and LED light 2 connection supply
Electricity.
In use, connecting direct current by equipment charge mouth 6, direct current is provided to charge power supply 7, then dry cell in parallel
8,7 are turned on the power switch, tests whether to leak electricity by earth leakage protective device 9；It is then shut off power switch 10, pointer multimeter 11 passes through
Conducting wire is connected on operation plug-in strip 12, makes the anode of the high-pressure side L1 access direct currents of primary connection terminal 4, primary connection
The cathode of the high-pressure side L2 access direct currents of terminal 4, the low-pressure end K1 accesses pointer multimeter 11 of secondary wiring terminals 2 is just

Electricity, closes or the swaying direction of 12 process observation pointer multimeter 11 of opening operation plug-in strip, judges whether polarity；When operation plug-in strip
12 close moment, and pointer multimeter 11 is swung to positive direction, 12 moment of opening operation plug-in strip, and pointer multimeter 11 is to negative side
To swing, then it is same polarity that direct current, which connects the terminal that electric positive terminal connects electric anode with pointer multimeter 11, at this time mutual inductor
For subtractive polarity terminal, conversely, being then additive polarity terminal；When needing night use, LED switch 3 is opened, LED light 2 is made to illuminate.
