1. sky opens tripping operation principle
Sky of domestic distribution box opens wiring to form objective plan
Alleged sky leaves, namely air switch, breaker of professional term air, it is to use control in our home total power supply and different area (wait like kitchen, toilet, air conditioning) distribute power supply, the electric current that should have flowed to leave for nothing only exceeded it can susceptive is rated electric current, it is met tripping operation.
The sky of different type leaves
To go to the lavatory below explain, we are necessary to understand the meaning that opens the label that go up for nothing, the classification that leaves for nothing is very much, we basically say housekeeping money, for example: Wrote above air switch " DZ47-63, c25 " , among them, DZ47-63 is model (DZ represents breaker of type of plastic outer covering) , the country is general-purpose date, 25 it is 25A of value of rated electric current, c is switch take off buckle (movement) curve (miniature breaker still has curve of A, B, D, suit at different environment just) , the C32 in as above graph is rated electric current the value is 32A. Understood this, it is how old that we can know the sky in the home opens rated electric current, also know it can susceptive electric current is how old.
Open structure of the interior when be in condition closing gate for nothing
Leave for nothing be in disconnect structure of the interior when condition
Three-phase sky opens behavioral principle to pursue
Voluntary action principle: When circuit produces run-of-mill overload, although overload electric current cannot make electromagnetism is taken off buckle implement movement, but can make hot component produces certain quantity of heat, make bimetallic piece be heated upsweep, drive lever to make build hook and lock come away, will advocate the disjunction that touch a head, dump. Short-circuit when circuit or when serious overload electric current, short-circuit current exceeds instantaneous to take off buckle make cost of calm electric current, electromagnetism is taken off buckle implement generation is enough big attraction, suck armature amalgamative bump lever, make build a hook to circle runner shaft up roll and lock come away, lock falls in the action of the bedspring that return power third mate advocate the disjunction that touch a head, dump. (principle graph is owed mediumly press buckling is another suit buy, be not article key)
Breaker of leakage of electricity
Leave to want to be able to distinguish with breaker of leakage of electricity for nothing: Breaker of leakage of electricity also says leakage is protected, leakage of electricity, short circuit, overload appears to break a tripping operation automatically in husband. Leakage protects comprise by two parts: One part is breaker, another part is protector of movement of odd electric current, both combination has overload, short circuit to protect action already together, again leakage of electricity protects action, can prevent to get an electric shock accidentally. If be to leave for nothing merely, it is not effective to leakage of electricity. The loop that use phone waits except illume, toilet in average home (the place that hand may touch, change bulb for instance, the likelihood when bathing leakage of electricity) , other can use air switch control. Say simply, leaving for nothing use protective circuit, breaker of leakage of electricity is can protect circuit already, OK also tutelar.
Sketch map of principle of movement of protector of odd electric current
Protector of odd electric current, abbreviation is RCD (listening to others to speak so when the abbreviation of foreign flavour, what is we also know) , its working principle as above pursues, narrate with straightaway word even if: There is voltaic check line in-housely to encircle in breaker, when the electric current that should go out and the electric current that come back differ (size is decided according to rectifying) or original front line did not go out electric current, but answer an incoming telegram to flow from loop line, take off buckle coil to be able to drive breaker to take off arrest orgnaization movement.
Leave to be compared with breaker of leakage of electricity for nothing, because latter returns the function that has tripping operation of leakage of electricity, become so when tripping operation of breaker of leakage of electricity, breakdown is checked may bother little relatively.
2. sky opens platoon of tripping operation breakdown to check
Face the understanding of tripping operation principle through going up, the electric current that we know to bring about tripping operation no more than to had flowed namely greatened (short circuit, the electric equipment of high-power perhaps was bought again in the home, make circuit excess load) or leakage of electricity, of course breaker is likely also bad.
The sky in the home opens position now besides total brake, it is illume and electrical outlet part, we say the tripping operation that socket causes first, the tripping operation that socket causes divides a lot of cases again, after jumping for instance flat do not close to go up, some can close, but with return meeting tripping operation a little while!
Socket causes breaker tripping operation, do not close the case that go up:
- Had better look for a screwdriver that takes insulation, the laden line below pick off breaker, try to whether can close next, can explain circuit has trouble (continue to see 2) , cannot explain this breaker is bad, need is changed new. Receive the laden line of pick off afresh go up, next this all the way pilot is all inside area unplug entirely with electric equipment electrical outlet, ensure after joining with electric equipment, try to close gate again. Can explain with electric equipment breakdown (continue to see 3) , there cannot be trouble in demonstrative circuitry (continue to see 4) . If be to should decide breakdown of which electric equipment, we should fall in the circumstance that puts out breaker, go be being discharged one by one check, below the case that closing gate for instance, in the sky insert the outlet of tone, close gate next again, if do not close to go up (go up a little push, the feeling is not hanged when going up, do not go be being pushed forcedly, have short circuit probably) , explain air conditioning has a problem; If can close, after we break dam up water, go inserting test of another electric equipment again. Do not fall in electrify circumstance, of many a electric equipment go inserting, if be electric equipment leakage of electricity, do the dangerous sex with have certain so. We should follow this one step of an electrical outlet go discharging check, workload is met a little a bit bigger. Begin from a farthermost first, socket debus comes (the chamfer that there is to be able to use one word screwdriver to lever face plate below socket, screw can see after levering) , pick off front line, come to live wire defray rise high into the air is placed, do not want lay a finger on to assume a post why elsewhere, go closing gate next, if do not close, the electrical outlet of pick off does not want to move temporarily, continue to pick next electrical outlet, till discovery pick off after a certain electrical outlet, can close, at this moment we are nodded from breakdown very stood by. Then we go to the electrical outlet of other pick off one by one restoring again, restore an attempt syncretic second brake, it is OK to such doing a line that has trouble or electrical outlet discharge fish to come. Because of the electrical outlet from the back, we also may forget (or knows far from) , it receives the past from the where of nearby. If alone finally with respect to remnant an electrical outlet causes tripping operation, we can change new electrical outlet, perhaps abandon need not. According to my experience, this kind of circumstance, get offline damp circumstance is in the majority inside the box, want to continue to use, need solves damp problem.
Socket causes breaker tripping operation, can close but the circumstance that jumps a little while:
- The platoon investigates case of electric equipment leakage of electricity (premise is recently did not add electric equipment, and these circumstances had not appeared in be being used before these electric equipment) , after breaking dam up water, unplug electrical outlet of all electric equipment entirely, close gate next, look whether tripping operation, if tripping operation, demonstrative circuitry has trouble (continue to see 2) ; If not tripping operation, explain circuit is no problem, the problem depends on electric home appliances
Illume causes breaker tripping operation:
- If be being decorated recently, the likelihood appears this kind of circumstance, when the electrician that average user individual or technology close nevertheless is changing circuit, when wanting to add electric lamp or electrical outlet, nearby down-lead, but draws 0 lines and live wire cent belong to two breaker, cause tripping operation thereby. This kind of circumstance, need from the down-lead in same way. Specific knowing is the tripping operation that when wanting to turn on which lamp, appears (for instance desk lamp) , undertake checking to the lamp next, it is wired wore away, when perhaps be being installed at that time, the line did not screw, strike a light is hit to now, cannot use eventually.
Actually, no matter face what situation, we should be recollected well above all, recently is to be in in the home when to discover leave for nothing appeared breakdown, rained recently for instance? Go to splashing not carefully recently on socket? Be the case that there was tripping operation after bathing? Fill always is when heating water with electric jug is full, after water leaves, meet every time slop a lot of water? ...
In follow-up article, we can be shared mix about ground connection, 0 lines equipotential a few knowledge that wait a moment, with their recombine today's content, we can discover everything is not so difficult!
Today's share arrive here! Content is scanty shallow, if have misgivings, forgive please!
