Ut ad curare personalis salus et necessitates potentiae ratio, sunt severus requisita ad grounding de Diesel generantis paro. Tria genera ratio modi operantes grounding, praesidium grounding et tutela nulla. Ad grounding est ut sequitur:
I. Grounding opus
Opus terram est ad terram neutrum punctum ad:
I) reducere electrica inpulsa voltage. Nam ratio cum impensae neutram, cum tempus pertinet ad terram et humanum corpus tangit unus de aliis duo phases, in inpulsa intentione plus 1.7 temporibus tempus voltage; Nam neutrum terram systems, in inpulsa intentione reducitur ad proxima vel aequalis ad tempus voltage.
II) cito interficiam off vitiosa apparatu. For the system with ungrounded neutral point, when a phase is connected to the ground, due to the existence of capacitance and insulation resistance in the wire and ground, the current path can be formed, and the grounding current is small, which is not enough to make the protection device operate and cut off the power supply, and cannot ensure personal safety. Nam neutrum punctum grounding ratio, cum in terra current est magna post tempus grounding, tutela fabrica erit celeriter agere ad DEJUGO est culpa punctum.
III) reducere ad insulationem gradum electrica apparatu ad terram. In systema ubi neutram punctum non fundatur, cum tempus sit funditus terra voltage alterius duo augmenta erigetur lineam voltage. Nam neutrum terram ratio cum tempus connectitur terra humi voltage alteri duo gradus est prope ad tempus voltage, ita in oratione electrica apparatu et traductionem lineae gradu potest reduci.
II. Grounding Tutela
Protective grounding is often used in low-voltage systems where the neutral point is not grounded, its role is: when the insulation structure of a winding of the motor has been damaged so that the shell is charged, if it is not grounded, the human body hits the shell, which is equivalent to single-phase electric shock, and the risk of electric shock may occur. Si tutela grounding adhibetur, cum humanum corpus tangit testa, resistentia humani corporis est in parallel cum grounding resistentia, propter resistentiam humani corporis; Multo altior quam terra resistentia, in hodiernam per humanum corpus est valde parvum, illic erit periculum electricum inpulsa.
III. Praesidium Iungo ut nulla
Protective zero is often used in neutral ground low-voltage systems, its role is: when the insulation structure of a winding of the motor has been destroyed and connected with the shell, due to the use of protective zero, the formation of single-phase short circuit, quickly fuse this phase in the fuse, the shell will no longer live. Etiam corpus tangit crusta ante fuse est canitur, quia resistentia corporis multo maior linea resistentia, hodiernae per corpus est valde et non est periculum electricum inpulsa.
Nam magis quaestiones circa generantis set, placere vocant beidou potentia dolor. Plus quam decem annos professional productio et Sales de potentia generationem apparatu experientia, magis professional ipsum quadrigis servire vobis, eligere beidou potestate est eligere quieti certo, grata, site officinas inspectionem.
