Calaamadinta jebiya. Noocyada, sifooyinka iyo mawjadaha Ujeedada

Marka la barbar dhigo Iyo mawjadaha circuit caadiga galiyey golaha wasiirada iyo waxaa loogu talagalay si loo ilaaliyo taararka ka wareeggeedii gaaban iyo overloads inta lagu guda jiro mawjadahaa. mawjadaha Calaamadinta codsatay in ay jidhka, waxa ku jira sifooyinka ay ugu weyn. iyaga On aad ka heli karto sawir buuxa oo ah qalabka.

Mawjadaha Circuit: calaamadeynta iyo sixitaanka

Waxaa jira noocyo badan oo ka mid ah mashiinada, tusaale ahaan, nooca jir - AE20HHH.

Tusaale ahaan, waayo AE2044 mashiinka lagu calaamadiyey tarjunto sida soo socota: 20 - Horumarinta, 4 - 63 A, 4 - unit safar hal pole kaamerada iyo electromagnetic. Qalabka waxa lagu gartaa jirka karbolitovogo midab madow ah dabeecad u.

nidaamka lagu calaamadiyey si toos ah waxaa cabiran. Ujeedada ugu muhiimsan ee ay tahay in la keeno ugu cad in dadka isticmaala ku soo koobin ugu muhiimsan ee qalabka.

Calaamadinta mawjadaha akhriyi on jidhka ka soo top si hoose.

1. saaraha ama summad - Schneider, ABB, iek, EKF.
2. Tirada Serial ama tusaha (taxane S200U, shirkadda SH200 ABB).
3. Time-hadda sifo (A, B, C) iyo rating ampere (I _naanaysta.).
4. danab lagu qiimeeyo.
5. qiimaha ugu badnaan la ogolaan karo breaking hadda k. S.
6. Class xadka hadda.
7. Part saaraha, kaas oo aad ka heli kartaa noocan ah mashiinka ee buugga.

Sawirka hoose wuxuu muujinayaa sida loo sixitaanka mawjadaha ABB iyo Schneider.

furitaanka pushbutton calaamadeeyay ama tilmaamay in cas. Haddii ay tahay mid ka mid ah oo keliya, iyo ku cidhiidhinaya la sameeyo, ka dibna booska ilig ah oo macnaheedu yahay in circuit xiran yahay.

Calaamadaynta ee jebiya wareeg ee soo saarayaasha ugu waaweyn waxaa ka mid ah QR code-, halkaas oo dhammaan macluumaadka ku saabsan model waa ka muuqataa. Joogitaankooda waa nooc ka mid ah damaanad ah oo tayo leh.

Saamaynta ay ku deegaanka

1. kala duwan ee heerkulka for moodooyinka caadiga ah waa in kala duwan ee ka -5 ° C si +40 ° C. Si aad u shaqeeyaan dhaafsiisan, kuwaas oo soo saaray nooc gaar ah.
2. Oggol yahay qalab shaqada huurka qaraabo of 50% at 40 ° C. Iyada oo hoos u ogolyahay heerkulka qoyaan kordhay (ilaa 90% at 20 ° C).

nooca mishiinnada

Mashiinada lagu doorto ku xiran Bannaanka korontada.

1. Hal-cirif automatic

Qalabka loo isticmaalo in shabakadaha-hal waji. Wajiga xiran terminal sare iyo load - si hoose ee. Ku xiridda qalabka la soo saaray ee silig wajiga farqiga u baabbi'iyo amar ay load ee xaaladaha degdega ah.

2.-cirifoodka Machine

Qaab ahaan, qalabka waa block a of laba odnopolyusnikov xiran lever. Quful dhexeeya hab off waxaa loogu talagalay si ay wajiga of eber ka hore (sida ku cad shuruucda ee SAE ah).

3. mashiinka saddex-pole

Qalabka loo isticmaalo in ay xidhi doonto korontada ee network saddex waji in ay dhacdo shil. Saddex-dhibic isku daraa 3 odnopolyusnika la qabsiga hawlgalka isku mar. The daayo electromagnetic iyo kulka si gooni gooni ah loo sameeyaa, waayo, circuit kasta.

breaker: sooc

Mashiinnada waxaa laga yaabaa in sifooyinka kala duwan waqti hadda:

a) ku tiirsan tahay hadda,
b) ka madax banaan hadda ah;
c) laba tallaabo ah;
d) saddex-yada.

On godadka mashiinada badan aad ka arki kartaa warqado magaalada B, C, D. Calaamadinta mawjadaha B, C, D tusinaysaa sifo ay ka muuqato ku tiirsanaanta waqtiga jawaabta ee K xiriirka mishiinka ah = Waxaan / ayaan _naanaysta.

1. B - ilaalinta kaamerada waxaa firfircoonaan iyada oo 4-5 la ka badan 3 jeer qiimaha magacaaban, iyo electromagnetic - in 0,015 seconds. Qalabkaas waxaa loogu talagalay ugu rarataan culaysyo la hadda inrush hooseeyo, gaar ahaan iftiinka.
2. C - sifo ugu badan ee mashiinada si ay u ilaaliyaan xarumaha korontada la dhexdhexaad hadda inrush.
3. D - for mashiinada la hadda load weyn bilowdo.

feature The been sifo waqti hadda ka jirta xaqiiqda ah in la noocaas oo kale ah mashiinada madaahibta B, C iyo D waa la bakhtiin doonaa hawlgalka at exceedances hadda kala duwan.

Noocyada kale ee mashiinada

1. MA - iyada oo aan la sii daayo kaamerada. Haddii silsiladda ayaa lagu wadaa Relay hadda, oo ku filan in la dhiso breaker oo keliya ilaalinta-circuit gaaban.
2. A - daayo kulaylka waxey imaneysaa marka aad iyo aad ayaan _naanaysta. 1.3 jeer. Xaaladdan oo kale, markii hurdo wuxuu noqon karaa 1 hr. Haddii qiimaha dhaafto 2 jeer ama in ka badan, sii daayo hadda waxey imaneysaa iyada oo loo marayo 0.05. In case of failure of ilaalinta this sii marayo 20-30 leh ilaalinta kulayl. Mashiinka A leh dabeecad u ah waxaa loo isticmaalaa si ay u ilaaliyaan qalabka elektarooniga ah. Waxaa sidoo kale codsatay in ay Z. sifo qalabka

Shuruudaha xulashada automatic

1. Waxaan _naanaysta. - xad-dhaaf ah ee taas oo horseedaysa a keenaysay ilaalinta dollar ah. Heshaan soo xulay sida ay xarkaha hadda ugu badnaan la ogolyahay, ka dibna waxa loo yareeyo in 10-15%, waxaa xulashada kala duwan ee caadiga ah.
2. actuating hadda. Beddelashada Class of baxsadeen oo Bannaanka la doorto waxay ku xiran tahay nooca load. Ujeedooyinka qoyska, sifo ugu badan ee S.
3. Selectivity - hantida xiritaanka la xushay. Mashiinnada xulay rating hadda, in qalab ugu horeysay si fiican u shaqeeyay kooxda load ah. First, dami ilaalinta ee meelaha circuit gaaban ama network buux dhacdaa. takoorka Time la doortay si ay waqtiga jawaabta ahayd mid ka dheer, waayo, mishiinka, oo ku yaalla u dhaw in ay korontada ka.
4. Number of ulo. On saddex waji aqbasho mashiinka ku xiran afar ulo, iyo wajiga hal - hal ama laba. qalabka iftiiminta iyo reerkiisii oo ay maamulaan on odnopolyusnikah. Haddii guriga uu leeyahay kuleeliyaha koronto ama motor saddex waji leh, mashiinada saddex-cirif waxaa loo isticmaalaa iyaga u.

fursadaha kale

Marka breaker sifo ay heleen waa in la doortay si waafaqsan shuruudaha isticmaalka iyo isku xirnaanta. mashiinka kasta waxaa loogu talagalay tiro cayiman oo wareegyada hawlgalka. Sida ku biiro load ah laguma talinayo in la isticmaalo. Tirada mashiinada baahan doortay. U hubso in aad dhigay furitaanka, oo waxay ka daba - on warbaahinta line iftiinka iyo si gooni gooni ah si ay macaamiisha awood badan. Hababka for kordhaya daydo kala duwan kala duwanaan karaan. Sidaa darteed qalabka soo xulay mid ah lagu rakibay ee golaha wasiirada ah.

gunaanad

Calaamadaynta ee jebiya circuit ayaa loo baahan yahay si ay u doortaan sida ay baahidaada gaarka ah. sifooyinka ay si toos ah oo la xidhiidha qaybta taararka iyo noocyada load. Marka circuit gaaban dhacdaa ugu horrayn jilaafada daayo electromagnetic, inta lagu guda jiro overloads sii dheerayn - ilaalinta kaamerada.
