Qhov txawv ntawm lub nplhaib lub ntsiab chav tsev thiab switchgear
Apr 08, 2022
Lub switchgear muab faib ua ob hom: siab thiab tsawg voltage. High voltage muaj xws li lub nplhaib lub ntsiab chav tsev, nruab nrab txee, &1A, thiab lwm yam. Nws kuj muaj ntau hom nplhaib lub ntsiab units.
The ring main unit means that each power distribution sub-bureau has a switch cabinet (outgoing switch cabinet), and the busbar of this switch cabinet is also a part of the ring trunk. That is, the cylinder is made up of the busbars of each outlet cabinet. Each outlet cabinet is called a "ring main unit".
In fact, if you take out a ring main unit alone, you cannot see the meaning of "ring network". These ring main units are not large, so the high-voltage switch of the ring main unit generally does not use a circuit breaker with a complex structure, but a high-voltage load switch with a simple structure and a high-voltage fuse.
Uas yog hais, lub siab -voltage hloov nyob rau hauv lub nplhaib txee feem ntau yog ib tug load hloov. Lub tshuab hluav taws xob siv hluav taws xob hloov hluav taws xob los ua haujlwm tam sim no thiab lub fuse tshem tawm qhov luv luv tam sim no. Ob qhov sib xyaw ua ke los hloov cov hluav taws xob hluav taws xob. Tau kawg, qhov no tsuas yog txwv rau qee lub peev xwm.
