High-voltage Distribution txee - Cov khoom siv hluav taws xob rau lub zog hluav taws xob tsim hluav taws xob

High-voltage fais fab tuag txee xa mus rau cov khoom siv hluav taws xob siv rau kev tawm-tawm, kev tswj lossis kev tiv thaiv hauv kev tsim hluav taws xob, kev sib kis, kev faib tawm, kev hloov hluav taws xob thiab kev siv hluav taws xob, nrog rau qib voltage xws li 3.6kV txog 550kV, feem ntau suav nrog high-voltage Circuit Court breakers, high-voltage Isolation hloov thiab grounding hloov, high-voltage load hloov, high-voltage automatic reclosing thiab sectionalizer, high-voltage kev khiav hauj lwm mechanism, high-voltage tawg-pov thawj fais fab faib khoom thiab high-voltage hloov txee, thiab lwm yam. Kev lag luam high-voltage hloov kev lag luam yog ib feem tseem ceeb ntawm lub zog xa hluav taws xob thiab hloov khoom siv kev lag luam thiab ua haujlwm tseem ceeb hauv kev lag luam hluav taws xob tag nrho.

Lub tshuab hluav taws xob faib hluav taws xob muaj lub luag haujlwm ntawm cov khoom siv hluav taws xob sab hauv thiab sab nraud, cov kab nkag thiab cov kab tawm, thiab kev sib txuas ntawm busbar.

muaj pes tsawg leeg

Lub txee faib hluav taws xob yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm GB3906-1991 "3-35kV AC hlau-kab switchgear" tus qauv. Nws muaj ob qhov chaw: lub txee lub cev thiab lub Circuit Court breaker. Nws yog tsim los ntawm mechanism, theem nrab davhlau ya nyob twg thiab kev sib txuas.

Cov khoom siv txee

1) Txias dov steel phaj lossis lub kaum sab xis hlau (rau vuam txee);

2) Aluminium-zinc steel ntawv lossis galvanized steel ntawv (rau cov khoom sib dhos);

3) Stainless hlau phaj (tsis yog hlau nplaum);

4) Aluminium phaj ((tsis-magnetic).

functional unit

1) Main busbar chav tsev (feem ntau lub ntsiab busbars yog teem nyob rau hauv ob tug qauv ntawm "pin" puab los yog "1" puab)

2) Circuit Court breaker chav

3) Cable chav

4) Relay thiab ntsuas chav

5) Chav tsev me me rau saum lub txee

6) Chav tsev thib ob
