Continuously adjustabe between 170V, can meet breaker tripping and closing voltage that inspection procedure specifies in this requirement of the 30%-65% of 220V, breaker tripping and closing
Coil is inductive nature, can produce high pressure back-emf when test, components and parts in control box constitutes certain threat, protects module
Effectively solve this problem in that, back EMF control at about 250V, thus ensure the safety of operation circuit；Output sky open be for
Prevent because tester internal fault causes breaker operator loop abnormal, when carrying out testing the same period to chopper, external testing
Instrument starts internal relay, is 3ms through busy relay intrinsic movement time, and test result should deduct the intrinsic action of relay
Time, operation full voltage being added on tripping coil, it is ensured that the accuracy of test, it is empty that direct current input first passes through switch S4
Opening, switch S3 handle select, carry out pressure regulation or full voltage test, during selection pressure regulation, display 23 can show magnitude of voltage,
Being divided into combined floodgate test or tripping operation test, voltage is opened output to terminal block breaker tripping and closing voltage link by output sky again through protection board 24
On, circuit connection need not be removed, by potentiometer R8, voltage is adjusted, integrated circuit U3 range of regulation is 1.25-125V
Between, through Zener diode D4, voltage being suspended to minimum about 55V, the upper limit is 175V, and electric current expands through 2 2N3055
Export after stream, when selecting full voltage, be mainly used to coordinate the chopper test same period, it is also possible to carry out the jumping of chopper with full voltage
Closing operation, the switch tester activate switch closing relay K1 same period, switch separating brake relay K 2, relay K 1 and relay K 2
Operation voltage is applied directly on tripping coil through protection board 24, and switch S7, switch S8 button can be directly operation electricity
Pressure is applied on breaking coil, thus directly carry out point, conjunction chopper.
Embodiment 3, in conjunction with accompanying drawing 6 ~ 7, implements a kind of chopper online breaker tripping and closing voltage tester described in the utility model
Instrument, in use, first the model according to cable selects the snap ring of dimension, then by the first cable 33 and the second cable 41 points
It is not inserted in the first snap ring 32 and the second snap ring 40, at this moment opens the lid 28 on air bag 36 gas outlet 30 above, then press
Press two corresponding rollers 35 so that roller 35 does relative motion, under the effect of roller 35, the first snap ring 32 and the second card
Ring 40 is in adverse movement, and the cutting knife on the first connecting plate 31 that two such is relative will be cut, so that cut in cable
Cutter is connected with the core in cable, owing to cutting knife, first snap ring the 32, second snap ring 40 and roller 35 are conductive material, therefore
First cable 33 is connected with the second cable 41, when the first connecting plate 31 and the second connecting plate 38 linearly when, that
That is the first cable 33 is connected thoroughly with the second cable 41, and same clamp device is the most just fixed
, the dop 39 on clamp device is connected with draw-in groove 42 or the first hook 44 is connected with the second hook 45, such two
Cable is just fixed, and now the air in air bag 36 is discharged in the gas outlet 30 of air bag 36, is at this moment covered by lid 28
Just so that air bag 36 is in vacuum state in gas outlet 30, thus it is greatly reduced the probability of oxidation, extends
In service life, it is additionally, since the such structure of employing, fixing both threads cable when, need not special Crimping Pliers the most permissible
, thus greatly facilitate daily work.
The non-detailed portion of this utility model is prior art, although combining preferred embodiment specifically show and describe this
Utility model, implements this technical scheme method and approach is a lot, and the above is only the side of being preferable to carry out of the present utility model
Formula, but those skilled in the art should be understood that in the essence of the present utility model limited without departing from appended claims
In god and scope, this utility model can be made a variety of changes in the form and details, be protection of the present utility model
Scope.
