What is self switching and self restoring? When the main power supply is in normal condition, the main power supply is automatically put into use, and the standby power supply is standby; When the main power supply loses power, the control device disconnects the main power supply circuit breaker, the standby power circuit breaker is closed, and the standby power supply works; When the main power supply restores the power supply, the control device disconnects the standby power supply circuit breaker, the main power circuit breaker is closed, and the main power circuit breaker is restored to power supply. What are alternate functions? When the main power supply is in normal condition, the main power supply is automatically put into use, and the standby power supply is standby. When the main power supply fails or loses power, the standby power supply is put into use. If the main power supply is back to normal, it will no longer automatically switch to the main power supply. The power supply can only be switched to the main power supply only when the artificial switching or standby power failure or loss of power occurs. What is overload? Overload refers to the actual load exceeding the rated load. This is mostly due to electrical equipment increased, the power consumption exceeds the capacity approved by the power supply enterprise or the design use capacity of the electric circuit, which will result in burning of metering device and electric equipment. What is overload protection? When the circuit current exceeds the rated value, according to the amplitude beyond the set of different action time limit, and can avoid the motor start and the like short-term overload. what is a short circuit? In a normal power supply circuit, the current flows through the wire and the electrical load, and then goes back to the power supply to form a closed loop. But if in the circuit that the current passes through, two wires are touched together, or by other small resistance objects short circuited, this is called short circuit. What is short circuit protection? Short circuit protection means that the power supply can be cut off quickly and reliably after the short circuit fault occurs in the electrical circuit, so as to avoid the damage to the electrical equipment caused by the short circuit current.

Sé Common Sense go mór le Leictreoir Know Cad é féin lasctha agus féin a athbhunú? Nuair a bhíonn an soláthar cumhachta is mó i riocht gnáth, tá an soláthar cumhachta is mó a chur go huathoibríoch in úsáid, agus is é an soláthar cumhachta fuireachas fuireachas; Nuair a chailleann an soláthar cumhachta is mó cumhachta, an comhoibriúntrol disco gléasnnects an breaker is mó soláthar cumhachta chuaird, tá an breaker ciorcad cumhachta fuireachas dúnta, agus na n-oibreacha soláthair cumhachta fuireachas; Nuair a restores an soláthar cumhachta is mó an soláthar cumhachta, an comhoibriúntrol disco gléasnnects an breaker ciorcad fuireachas soláthar cumhachta, tá an breaker ciorcad cumhachta is mó dúnta, agus tá an t-breaker ciorcad is mó cumhachta ar ais ar an soláthar cumhachta. Cad iad feidhmeanna malartach? Nuair a bhíonn an soláthar cumhachta is mó i riocht gnáth, tá an soláthar cumhachta is mó a chur go huathoibríoch in úsáid, agus is é an soláthar cumhachta fuireachas fuireachas. Nuair a theipeann ar an soláthar cumhachta is mó nó cailleann cumhachta, tá an soláthar cumhachta fuireachas a chur in úsáid. Má tá an soláthar cumhachta is mó ar ais go dtí gnáth, beidh sé aon longer go huathoibríoch soláthar cumhachta is mó. An soláthar cumhachta is féidir oa aistrigh nly go dtí an príomh-soláthar cumhachta only nuair a tharlaíonn an t-athrú saorga nó cliseadh cumhachta fuireachas nó caillteanas cumhachta. Cad é ró-ualach? Tagraíonn Overload leis an t-ualach iarbhír níos mó ná an t-ualach rátáil. Tá sé seo den chuid is mó mar gheall ar trealamh leictreach méadaithe, an co cumhachtansumption sháraíonn acmhainn ceadaithe ag an bhfiontar soláthar cumhachta nó cumas úsáide ar dhearadh an ciorcad leictreach, a mbeidh de thoradh dhó gléas méadraithe agus trealamh leictreach. Cad is cosaint overload? Nuair a théann an t-atá ann faoi láthair chuaird an luach rátáilte, i gcomhréir leis an aimplitiúid níos faide ná an tacar teorainn éagsúla ama gníomh, agus is féidir a sheachaint an tús mótair agus a leithéidí overload gearrthéarmacha. Cad é ciorcad gearr? I chuaird soláthar cumhachta gnáth, sreabhadh an sruth tríd an sreang agus an t-ualach leictreach, agus ansin téann ar ais go dtí an soláthar cumhachta chun foirm a lúb dúnta. Ach más rud é sa chiorcad a théann an sruth ag dul trí, tá dhá shreang i dteagmháil léi le chéile, nó trí frithsheasmhacht beaga eile réada gearr circuited, seo ar a dtugtar chuaird gearr. Cad is cosaint chuaird gearr? Ciallaíonn cosaint chuaird gearr gur féidir leis an soláthar cumhachta a ghearradh as go tapa agus go hiontaofa tar éis di an locht chuaird gearr sa chiorcad leictreach, ionas go seachnófar an damáiste don trealamh leictreach ba chúis leis an láthair chuaird gearr.
