Domestic circuit is general by take a line (also call power supply cord) , switch of electric energy watch, brake knife (it is air switch commonly now) , insurance equipment (the fuse that the other type such as air switch accords with a standard) , wait for composition with electric equipment, electrical outlet, lead, switch (mostly, a few circumstance establishs ties) .
Report, the application in our life is wider, it brought a lot of advantage to our life, we more and more cannot leave phone. because such, sometimes circuit breakdown brings a lot of inconvenience and trouble with respect to the life that gives us. I introduce method of the examination measure of breakdown of circuit of a few kinds of families and maintenance below.
Breakdown of common a few kinds of circuit
(1) bulb does not shine or glimpse.
(2) TV brightness is abnormal.
(3) unexpected power failure.
Be aimed at the examination measure of partial breakdown and maintenance method
(one) bulb is not bright, or glimpse
Not bright cent is 1. bulb two kinds of circumstances
(1) all bulb in the home are not bright. Very simple to the examination measure of this kind of circumstance, should see neighbour home whether have report above all, if neighbour home also does not have report, that may be power supply unit is undertaking breakdown is maintained, this kind of circumstance is done not have necessary go checking circuit. If neighbour home or other place have report, breakdown appeared on the fuse that is the circuit in the home then or dry road. And the maintenance of this kind of circuit is simpler also. If be fuse,broke, that should change superior fuse only can; And of dry roadOpen circuitWith respect to application conductor joins two end together. If finish,above measure bulb still does not shine, that may be the bulb in the home bad, but this kind of possibility is lesser, won't appear in commonly.
(2) among them a bulb is not bright. This also is the common phenomenon in the life, at this moment we should check this bulb to whether burn out above all, check switch and lamp holder then, whether does the line that final examination receives this spur track open circuit. To the first kind of phenomenon, should change a good bulb only can, but for managing, also can undertake to bulb " maintenance " (be about to the tungsten filament series connection inside bulb rises) . But the plan that is lash-up only so, the bulb life that because repair,lives will be very brief. If be switch and lamp holder bad, also be to be changed directly likewise new. Of course, the open circuit that the processing technique that spur track opens circuit also resembles handling dry way is same, with the two end that conductor will open circuit join rises can.
2. bulb glimpse
The phenomenon of bulb glimpse can appear in the process that we use phone sometimes. When producing this kind of situation, examining is a lamp only in the home twinkling still is a few. If be, have to check lamp holder to whether be contacted undesirable; Below the circumstance that ensures lamp holder is good, the examination receives the wiring part of this bulb, if was not received good, had received afresh can. If all bulb in the home twinkle, then we should visit neighbour home above all it is normal to use phone. If report of neighbour family expenses is regular, have to check fuse to whether be contacted undesirable, or whether is the wiring place of dry road contacted undesirable, if be a contact undesirable it is OK to had joined afresh in corresponding place.
(2) TV brightness is abnormal
TV brightness also has two kinds of cases out of order, namely power source and TV interior two kinds. Introduce examination of power source breakdown and maintenance method only here. When TV brightness is abnormal, possible reason is power source voltage is not stabilized, should check socket first in good condition, if have a problem, should change an in good condition electrical outlet only can; Next, the examination does a road to whether have trouble, or fuse contact is undesirable. To this kind of problem, receive very unified line afresh or be to change new fuse can. Solving voltage not to stabilize the best method of the problem is to install a manostat.
(3) unexpected power failure
Because all sorts of using,electric equipment applies in our life more and more extensive, a general power of useful electric equipment of some families is too great, adopt dry wayElectric currentExceed electric energy watch to allow the biggest electricity that carry, at this moment circuit can appear " tripping operation " phenomenon. Appear this kind of phenomenon need not alarmed, should avoid to be used at the same time as far as possible only many with electric equipment can. But whether is examination circuit is medium fuse burned out, if burn out,should change new fuse first, renew power supply again.
Safety uses phone
(1) safe voltage: Not the voltage of prep above 36V.
(2) the conductor that do not contact live wire or connects with live wire, the object that special attention is isolated from so guided report.
(3) do not stand by high-pressured electrical body, because high pressure gets an electric shock,have two kinds of kinds: High-pressured electric arc gets an electric shock and step voltage gets an electric shock, do not contact also can get an electric shock.
(4) processing getting an electric shock: Somebody produces accident getting an electric shock, absolutely need not the hand helps person getting an electric shock, should hasten dump, or choose the route with dry dielectric; High pressure gets an electric shock, appropriate informs professional personage at once.
(5) emergency treatment: If person getting an electric shock is insensible, should first dump, redo breathes artificially, send a hospital; If produce fire, answer to cut off the power first, again put out a fire.
