Voltage transformer - chinokosha Chishandiso

Makambani kuti mubasa kutenga, kutengeswa magetsi, kazhinji kuchengeta zvinyorwa kudyiwa zvinhu, kurasikirwa kukosha, uyewo anobatsira zvivako. For kwacho setsika kushandiswa kuitika uye voltage transformers. mano akadaro vanokwanisa kushanda flow pamusoro soro voltage pasina okuwedzera namano. midziyo kwakadaro aiendeswa mudziye yechipiri mumatunhu uye kunofambidzana tambo midziyo yemagetsi kubva kumusoro-voltage michina. Small tsika voltage uye kuitika kubvumira kuti vakadaro mano kupfuura chiine nyore.

Current transformers (CTs) anoshandiswa kutendeutsa dzenzvimbo hombe diki zvakawanda. Vane akakodzera kuyera dzakasiyana-siyana kwezvipimo zviridzwa. Uyezve, zvinoita here kuti kudzivirira tambo redunhu kubva inokanganisa pfupi redunhu.

inotevera TT kusiyaniswa design:

1. Reference.

2. Tire.

3. Built.

4. Kufamba.

5. Split.

6. Electrical pingisi.

The kuitika transformer iri sezvinotevera:

1. The kakawanda zvenguva akakodzera kushanda.

2. The coefficient tishandurwe.

3. Kutaura.

4. Kutaura.

5. Rated ano.

6. kunonyanyisa iyezvino.

Uyewo voltage transformer (VT) rinoshandiswa kuderedza kukura kuunhu dzinokodzera yakayerwa. Kuburikidza remagetsi coupling pamusoro nesekondari windings ari woga michina iri kuyera mumatunhu, uye kuparadzana runodzivirira ataure zvokushandisa mukuru-voltage Network. Kuti ave nechokwadi kuchengeteka electrotechnical vashandi kushanda mano izvi, mumwe zviteshi ari yechipiri ichitenderera iri makateyiwa. The runoratidza, iro rine voltage transformer, - zvarakanga nokushanda kwadzinoita pedyo idling. Panyaya iyi, kuti kurwisa anokosha zvakakwana guru, uye ano mutengo, nekusiyana, ishoma. Somugumisiro, transformer pfupi-redunhu voltage iri zvakaenzana kunoparadza zvikuru.

Mumwe VT ine maitiro ayo, varehwa maererano:

1. Akarurama, izvo kunobva simba rinonzi magnetic permeability uye rinobva marongerwo. Kuderera vachishingaira zvinoriumba anogona kuderedza muchichinjana iri rinonyanya ichitenderera, uye kushandisa compensating mudziyo.

2. Kutaura Rating.

3. coefficient tishandurwe.

4. kunonyanyisa voltage.

5. Rated voltage.

By kuvakwa zvavo danho uye zvitatu danho VT. First kushandiswa chero voltage, wechipiri - kuti voltage kusvika 18.000 V.
Maererano akashandisa kuputira dzoga yakaoma, jikichira uye vachikanda.
Kusiyana ano transformer iyo yaisanganisira mumidziyo mu series, mumwe voltage rwokuyeresa transformer chepuraimari ichitenderera kunofambidzana akaererana tambo redunhu.

Pakusarudza parameters akayera redunhu riri sezvinotevera: kukosha iyo anoratidza voltage transformer uye ano, kane nhengo kushanduka coefficient mudziyo.

The peculiarity kuti kuyera transformers ndechokuti zvinoita pachena yechipiri ichitenderera zvachose yakapedza vakachengeteka mitemo.
