K18-7.2(FC) cov khoom siv hauv tsev ua ke yog cov khoom siv hauv tsev hloov nrog qhov ntsuas hluav taws xob ntawm 7.2kV thiab AC zaus ntawm 50/60Hz. Nws yog tsuas yog siv nyob rau hauv KYN18C-12 armored tshem tau AC hlau-kaw switchgear nyob rau hauv ib tug parallel FC Circuit Court qauv, ua hauj lwm raws li ib tug ua ke lub hwj chim faib khoom nyob rau hauv lub hwj chim systems nrog rated voltage xws li 3.6kV mus rau 7.2kV. Nws yog tsim los tswj thiab tiv thaiv motors txog li 1200kW thiab transformers mus txog 1600kVA.

Khoom zoo

K18-7.2(FC) cov khoom siv hauv tsev ua ke muaj ntau yam zoo:

Lub neej ua haujlwm ntev heev

Siv lub tshuab latch contactors nrog lub neej ua haujlwm txog li 100, 000 cycles; electromagnetic tuav contactors muaj lub neej ua haujlwm txog li 300, 000 cycles.

Compact tsim

Redesigned conductive circuit layout tso cai rau lub tsheb chassis kom phim lub txee dav, txo nws mus rau 500mm.

Comprehensive kev khiav hauj lwm interlocks

Thaum siv nrog tshwj xeeb switchgear, FC chassis tsheb muab kev txhim khu kev qha thiab ua tiav tsib-tiv thaiv kev cuam tshuam.

Kev tiv thaiv ceev ceev

Siv lub tshuab tripping uas tshwm sim los ntawm high-voltage fuse's striker pin, ua kom tus contactor tuaj yeem txav mus los thaum lub fuse tshuab, muab kev tiv thaiv siab tshaj plaws.
