NZIRA DZEKUCHENGETERA PAKUSHANDISA MACHINJO EKUEDZERA AKANYWISWA NEOIRI

Nzira dzekudzivirira pakushandisa ma transformer anonyudzwa mumafuta ndeidzi dzinotevera:

1. Batanidza dunhu rekushanda zvichienderana nebvunzo inodiwa. Goko remuchina wekuyera wakanyikwa mumafuta negoko rebhokisi rekudzora (tafura) zvinofanira kunge zvakagadzikwa zvakanaka. X-end (muswe wemagetsi akakwira) wekutenderedza kwemagetsi akakwira wemuchina wekuyera wakanyikwa mumafuta neF-end yekutenderedza kwemuchina zvinofanirwa kunge zvakagadzikwa zvakanaka.

2. Pakuita bvunzo ye cascade, X terminal ye low-voltage windings yechipiri neyechitatu, F terminal ye measuring winding uye X terminal (high-voltage tail) ye high-voltage winding zvese zvakabatana ne casing ye test transformer yedanho rino. Casing yekunze ye test transformers ye second-nethird-level oil-immersed inofanira kugayiwa ne insulating support.

3. Usati wabatidza magetsi, muchina wekutonga magetsi webhokisi rekudzora re transformer rakanyudzwa mumafuta (yuniti) unofanirwa kugadziriswa kusvika pazero usati wabatidza magetsi, wavhara switch, uye watanga kuwedzera magetsi.

4. Tenderedza vhiri reruoko remutongi zvakaenzana kuti uwedzere kumanikidzwa kubva pa zero. Nzira dzekusimudzira ndeidzi: nzira yekusimudzira nekukurumidza, kureva nzira yekusimudzira nhanho nhanho ye20s; nzira yekusimudzira zvishoma nezvishoma, kureva nzira yekusimudzira nhanho nhanho ye60s; nzira yekusimudzira zvishoma nezvishoma yekusarudza.

Mushure mekunge voltage yakwira kubva pa zero kusvika pa 75% yevoltage yekuyedza yaunoda nenzira yakati yekusimudzira uye kumhanya, inokwira kusvika pavoltage yakayerwa yaunoda nekumhanya kwe 2% yevoltage yekuyedza yakayerwa pasekondi, uye nyatsoteerera kuyerwa kwezviratidzo zvemita nemamiriro echinhu chekuyedza. Kana chiratidzo chechishandiso chekuyera nemamiriro echigadzirwa chakayedzwa zvikaonekwa zvisina kujairika panguva yekuwedzera kwe transformer yekuyedza yakanyudzwa mumafuta kana panguva yekuyedza, kumanikidzwa kunofanira kudzikiswa nekukasika, simba remagetsi rinofanira kugurwa, uye mamiriro acho anofanira kuongororwa.

5. Mushure mebvunzo, chinodzora magetsi chinofanira kudzoserwa panzvimbo ye zero nekumhanya kwakafanana mukati memasekonzi mashoma, uye ipapo magetsi anofanira kugurwa.

6. Usapfuure ma parameter akatarwa. Kunze kwekunge zvichidikanwa pakuedza, usambobvumira simba rakazara remagetsi kana kuderedza simba.

7. Paunenge uchiita bvunzo yekupisa kwakanyanya, pamusoro pekuziva bhuku remirayiridzo yechigadzirwa, zvakakoshawo kushandisa mitemo yenyika yakakodzera uye maitiro ekushanda. Tarisa GB311-83 "Kubatanidzwa kwemidziyo yekudzivirira kupisa uye kushandura ine simba guru, tekinoroji yekuedza ine simba guru"; "Maitiro ekudzivirira emidziyo yemagetsi" nezvimwewo.
