Ga wani yadda ake amfani da bushing HV da LV a transfoma?

Muhimminci na Bushings na High Voltage da Low Voltage a Cikin Transformers

A cikin transformers, Bushings na High Voltage (HV) da Low Voltage (LV) suna kayayyakin muhimmiyar. Muhimmincinsu shine zuwa tushen bayanai daga karkashin transformer zuwa hanyoyi masu amfani ko kadan. Duk da cewa haka, wasu abubuwan da suke yi masu yawan muhimmiya su ne:

Bushings na High Voltage (HV)

Funkar Isolation:

• Isolation na Electriki: Muhimmincinsu da HV bushings ke shiga shine bayar da isolation na high voltage, domin kuma bayar da adadin current mai kyau ya zama daidai daga karkashin transformer zuwa grid ko load na gaba baki daya, bana da samun electric arcs ko wasu abubuwan da za su iya haifar da fadada.

• Yawan Daɗi na High Voltages: Saboda ingantaccen voltages (misali, kilovolts miliyan) an sa ta hanyar HV side, yawancin HV bushings suna buƙata da inganci na insulating don bayar da su dadi wajen kawo wannan voltages mai kyau bana da break down.

Ingancin Protection:

• Protection na Physical: HV bushings ba su shafi bayar da insulation na electriki kawai, amma suna buƙata da protection na physical wajen kawo internal conductors daga damage na mechanical saboda amfani na gaba (misali, dust, moisture, contaminants, etc.).

• Sealing: Bushings suna buƙata da performance mai kyau wajen kawo air, moisture, da wasu abubuwan daga gaba baki daya kafin suka zama da transformer, wanda ya iya haifar da aiki na normal.

Heat Dissipation:

A cikin wasu designs, HV bushings suna iya taimakawa wajen kawo heat away, musamman a cikin transformers na large-capacity inda adadin current ya fi yawa. Design na HV bushings suna buƙata da heat dissipation issues.

Bushings na Low Voltage (LV)

Funkar Isolation:

• Isolation na Electriki: Hakanan LV bushings suna shiga da voltages mai basu, suna buƙata da insulation na yawan adadin don bayar da low-voltage current ya zama daidai daga karkashin transformer zuwa hanyoyi masu amfani, bana da samun short circuits ko wasu abubuwan da za su iya haifar da fadada.

• Yawan Daɗi na Low Voltages: Ba sai dai ingantaccen voltages, LV bushings suna buƙata da level na yawan adadin na insulation don kawo partial discharge ko breakdown na insulation.

Ingancin Protection:

• Protection na Physical: Kamar HV bushings, LV bushings suna buƙata da protection na internal conductors daga amfani na gaba.

• Sealing: Kamar HV bushings, LV bushings suna buƙata da performance mai kyau don kawo contaminants daga transformer.

Funkar Connection:

• Connections na Gaba: LV bushings suna amfani a cikin connecting low-voltage side na transformer zuwa external loads ko grids, domin bayar da smooth transmission na current.

• Flexibility: A cikin wasu applications, design na LV bushings zai iya zama flexible, don bayar da installation da maintenance mai kyau.

Bayanai

• Bushings na High Voltage (HV) suna amfani a cikin handling current na high-voltage side na transformer, domin bayar da insulation na electriki da protection na mechanical a wurare na high voltage, kuma kawo amfani na gaba daga karkashin transformer.

• Bushings na Low Voltage (LV) suna amfani a cikin handling current na low-voltage side. Ba sai dai voltages mai basu, suna buƙata da insulation da protection na mechanical mai kyau don bayar da safe transmission na current.

Duka biyu na bushings suna bayar da transformer ya yi aiki da dalilai da inganci a cikin levels na different voltages.
