Section is convenient and will not generate any interference to DC loop, is the key that on-line testing, range of regulation DC 55-170V it
Between be continuously adjusted, be able to satisfy breaker tripping and closing voltage as defined in inspection procedure in this requirement of the 30%-65% of 220V, tripping coil is
Inductive nature can generate high pressure back-emf in test, constitute certain threat to component in control box, protective module is effective
It solves this problem in that, back EMF control in 250V or so, to guarantee the safety of operation circuit；It is in order to prevent that output, which is spaced apart,
Because tester internal fault causes breaker operator circuit abnormal, when carrying out same period test to breaker, external tester starting
Internal relay is 3ms by busy relay intrinsic actuation time, and test result should subtract relay intrinsic actuation time,
Operation full voltage is added on tripping coil, ensure that the accuracy of test, direct current input first passes through switch S4 and is spaced apart, by opening
It closes S3 handle to be selected, carries out pressure regulation or full voltage test, select display 23 when pressure regulation that can show voltage value, be divided into combined floodgate
Test or tripping test, voltage is spaced apart by output again by protection board 24 to be output on terminal block breaker tripping and closing voltage link, is not had to
Circuit connection is removed, voltage is adjusted by potentiometer R8, integrated circuit U3 range of regulation is between 1.25-125V, warp
It crosses zener diode D4 and voltage is suspended to minimum 55V or so, upper limit 175V, electric current is defeated after 2 2N3055 expand stream
Out, when selecting full voltage, it is mainly used to cooperate the test of the breaker same period, behaviour is closed in the jump that breaker can also be carried out with full voltage
Make, switch same period tester starts switch closing relay K1, switch separating brake relay K2, relay K1 and K2 behaviour of relay
Make voltage to be applied directly on tripping coil by protection board 24, switch S7, switch S8 button can directly make operation voltage
It uses on breaking coil, to directly carry out point, close breaker.
Embodiment 3 implements a kind of online breaker tripping and closing voltage tester of breaker of the present invention in conjunction with attached drawing 6 ~ 7,
In use, first selecting the snap ring of dimension according to the model of cable, then the first cable 33 and the second cable 41 are inserted respectively
Enter into the first snap ring 32 and the second snap ring 40, at this moment opens the lid 28 above air bag 36 on gas outlet 30, then press two
The corresponding roller 35 of root, so that roller 35 does relative motion, under the action of roller 35, the first snap ring 32 and the second snap ring 40
In counter motion, the cutter on the first opposite connecting plate 31 of two such will be cut into cable so that cutter with
Core in cable is connected, since cutter, the first snap ring 32, the second snap ring 40 and roller 35 are conductive material, so that
First cable 33 is connected with the second cable 41, when the first connecting plate 31 and linear the second connecting plate 38, then
That is the first cable 33 is thoroughly connected to the second cable 41, same clamp device is at this time just fixed, tightly
It is fixedly mounted with that the clamp 39 set is connected with card slot 42 or the first hook 44 45 is connected with the second hook, such both threads cable is just
It is fixed, and the air in air bag 36 is discharged out of the gas outlet of air bag 36 30 at this time, at this moment covers lid 28 in outlet
It can be so that air bag 36 be thus greatly reduced the probability of oxidation, extends using the longevity in vacuum state in mouth 30
Life, moreover, because using such structure, do not needed when fixed both threads cable dedicated Crimping Pliers can, from
And greatly facilitate daily work.
Part not in the detailed description of the invention is the prior art, although specifically showing and describing this hair in conjunction with preferred embodiment
It is bright, it implements the technical solution method and there are many approach, the above is only a preferred embodiment of the present invention, but affiliated neck
The technical staff in domain, which should be understood that, not to be departed from the spirit and scope of the present invention defined by the appended claims, in shape
In formula and the present invention can be made a variety of changes in details, be protection scope of the present invention.
