Ing kene, SPL, pabrik trafo China, menehi referensi babagan proteksi transportasi kecemplung lenga. Ana 3 piranti proteksi safety utama:

1, relay gas: digunakake kanggo 800kVA lan ndhuwur trafo kecemplung lenga. Nalika kapasitas kontak relay gas luwih saka 66VA utawa 15W lan akumulasi gas 250 ~ 300ml utawa ing sawetara disetel ing kacepetan lenga, kontak sing cocog kudu disambungake. Struktur lan posisi instalasi relay gas kudu bisa mirsani jumlah lan werna saka gas, lan iku gampang kanggo njupuk gas. Instal kanthi nambah 1.5% ing gradien. 220kV tutup tank lenga trafo uga kudu 1 ~ 1.5% tambah slope.

2, katup release meksa: digunakake kanggo 800kVA lan ndhuwur trafo; Nalika tekanan ing kothak lenga saluran udara safety utawa katup relief tekanan tekan 5.07 × 104Pa, kudu dibebasake kanthi andal. Loro katup relief tekanan kudu disetel kanggo trafo kanthi 120000kVA lan ndhuwur.

3, tutup, plug ventilasi: kabeh tembok tank trafo kudu dilengkapi tutup sampel lenga, 110kV, 90000kVA lan 220kV, 63000kVA lan ndhuwur tengah tembok tank uga kudu tutup sampel lenga. Tangki 315kVA lan ndhuwur kudu duwe piranti saluran ing sisih ngisor. Sisih ngisor tank trafo kudu tutup discharge lenga cukup gedhe, trafo 220kV uga kudu katup discharge lenga Laka. Trafo kudu ngetokake gas nalika ngisi lenga lan tes, saengga sisih ndhuwur alas trafo, radiator, bushing, lan sapiturute, dilengkapi plug ventilasi kanggo njamin keamanan trafo.
