Differential vs. Non-Differential Thermal Overload Relays: Liphapang tsa Bohlokoa le Tataiso ea Khetho

Selelekela

Tšireletso ea likoloi e bohlokoa bakeng sa ho thibela ho theoha ha theko e boima le tšenyo ea lisebelisoa. Mekhoa e 'meli e tloaelehileng ea ts'ireletso ke li-relays tse fapaneng tsa mocheso o feteletseng le li-relay tse ngata tse sa tšoaneng tsa mocheso. Le hoja ka bobeli li ikemiselitse ho sireletsa li-motor maemong a mangata, li fapane haholo ka mekhoa ea ho lemoha, lebelo la karabo, ho rarahana le litšenyehelo.

Phapang ea Thermal Overload Relay ke Eng?

A relay e fapaneng ea mocheso oa overload e beha leihlo mekhahlelo eohle ea makoloi ka nako e le 'ngoe ebe e bapisa maemo a hona joale. Haeba karolo e 'ngoe e hula ho feta tse ling, relay e tsamaea hang-hang. Karabo ena e potlakileng e thusa ho lemoha:

• Phase ho se leka-lekane

• Ho hloleha ha mokhahlelo

• Liphoso tsa motlakase ka hare

Litsamaiso tse fapaneng hangata li sebelisoa li-transformer tsa hona joale (CTs) bakeng sa papiso e tsoelang pele ea mekhahlelo, ho etsa hore e nepahale haholo ebile e ka tšeptjoa bakeng sa lisebelisoa tsa bohlokoa.

Relay e sa Feleng ea Thermal Overload ke Eng?

A e sa fapanang le mogote overload relay e itšetlehile ka lihlopha tsa bimetallic mokhahlelong ka mong. Ho feta hona joale marapeng ho hlahisa mocheso; haeba maqhubu a feteletseng a ntse a tsoela pele, likhoele lia kobeha ebe li baka leeto. Mokhoa ona o fana ka:

• Tšireletso e bonolo le e theko e tlaase

• Karabelo e butle-butle e ipapisitse le kaho ea mocheso

• Ts'ebetso e tšepahalang bakeng sa li-motors tse tloaelehileng tsa indasteri

• 

Phapang khahlano le Papiso e sa Phapanong

Karabelo le Phapano ea Theknoloji

• Li-relay tse fapaneng: Sebelisa CTs ho bapisa maqhubu a mohato ka mokhoa o tsoelang pele. Ho se leka-lekane leha e le hofe ho baka khato e potlakileng.

• Li-Relay tse sa Phapanong: Itšetlehile ka lintho tse futhumatsang mocheso ha nako e ntse e ea, ho bolelang tšireletso e liehang empa e bonolo.

Mathata a ho Hloma

• Li-relay tse fapaneng: E hloka li-CT tse ngata, li-wiring tse qaqileng, le ho lekanya ka nepo ke litsebi tse nang le boiphihlelo.

• Li-Relay tse sa Phapanong: Ho potlakile ho kenya ka li-setting tsa mantlha tsa hajoale, ho li etsa hore li tšoanelehe bakeng sa ts'ebeliso e akaretsang.

Molemo ka ho Fetisisa Likopo

• Li-relay tse fapaneng:

  • Li-motor tse kholo

  • Li-transformer tsa matla

  • Mekhoa e mahlonoko moo nako ea ho phomola e theko e boima

• Li-Relay tse sa Phapanong:

  • Lipompo

  • Fans

  • Bapalami

  • Li-motor tsa indasteri tse akaretsang

Litaelo tsa Khetho

• Boleng ba makoloi:

  • $5,000 kapa lits'ebetso tsa bohlokoa → Tšireletso e fapaneng e nepahetse.

• Boleng ba Matla:

  • Li-voltage tse sa tsitsang kapa liphoso tse etsahalang khafetsa li rata tšireletso e fapaneng.

  • Libaka tse tsitsitseng li sebetsa hantle ka li-relays overload overload.

FAQs

P: Phapang ea phepelo ea mocheso oa overload ke eng?
A: E bapisa phallo ea hona joale pakeng tsa mekhahlelo ea likoloi le maeto hang-hang ha ho se leka-lekane ho bontša ho hlōleha ha karolo kapa liphoso tsa ka hare.

P: Ke mefokolo efe ea li-relay tse fapaneng?
A: Litšenyehelo tse phahameng, ho kenngoa ho rarahaneng, le tlhokahalo ea ho lekanya ka litsebo.

Litharollo tsa Tšireletso ea Likoloi tsa Litsebi

Feela Reka lisebelisoa li-relay tse ngata tse fapaneng le tsa mocheso ho tsoa ho mahlale a etellang pele joalo ka ABB, Schneider, Siemens, le Eaton. Sehlopha sa rona sa litsebi se lekola lintlha tsa koloi ea hau le maemo a ts'ebetso ho khothaletsa leano le nepahetseng la ts'ireletso.
