Chitsanzochi chimagwirizanitsa makina ogwiritsira ntchito ndi chodulira dera, chokonzedwa bwino, chowoneka bwino komanso chophatikizika.2.Mchitidwewu ukhoza kugwiritsidwa ntchito kawirikawiri, wokhoza kuthyola ndi kutsekanso mofulumira nthawi zambiri.3. Mitundu iwiri yoyika (yokhazikika kapena yosuntha) imakwaniritsa zofunikira za ma switchgear osiyanasiyana.(VS1) -12 ndi HV indoor vacuum circuit breaker yomwe imagwira ntchito ngati chitetezo ndi chiwongolero cha zida zamagetsi zamagetsi ndi zida zamagetsi zamafakitale mumagetsi amagetsi ovotera kuchokera ku 7.2KV mpaka 12KV.Imakwaniritsa zofunikira za GB/T1984-2014 (AC HV circuit breaker) ndi JB355-1996 (3.6KV-40.5KV m'nyumba AC HV vacuum circuit breaker).Itha kugwiritsidwa ntchito pama switchgears a KYN28(GZS1), XGN ndi GG-1A.
Makina ogwiritsira ntchito ndi mtundu wamagetsi osungidwa opanda maulendo omwe amatsegula ndi kutseka mosasamala kanthu za zochita za wogwiritsa ntchito.Makina ogwiritsira ntchito amagwiritsidwa ntchito kwambiri pamagulu onse a VD4-R ozungulira omwe amawongolera kutsogolo.
Wowononga dera amatha kuyendetsedwa kutali atayikidwa ndi zida zamagetsi zodzipereka (gearmotor, kutsegula ndi kutseka kumasulidwa).
Makina ogwiritsira ntchito, mizati itatu ndi masensa omwe alipo (ngati aperekedwa) amaikidwa pazitsulo zachitsulo popanda mawilo.Chomangacho chimakhala chophatikizika, cholimba komanso cholemera pang'ono.
VD4-R mndandanda wophwanya ma circuit-breaker okhala ndi ma lateral opareshoni ndi zida zomata kwa moyo wonse. (Miyezo IEC 62271-100)
