Kev Ua Haujlwm Siab LW36-40.5 Circuit Breaker rau Cov Ntawv Thov High-Voltage
Qauv thiab lub ntsiab lus
Txheej txheem cej luam
Lub LW36 - 40.5 circuit breaker tau tsim los rau cov ntawv thov hloov capacitor bank, qhia txog kev hloov pauv zoo tshaj plaws hauv cov xwm txheej tso tawm capacitor hauv 750kV thiab 550kV substations. Siv lub hauv paus ntsiab lus ntawm tus kheej lub zog, nws muab kev ua haujlwm zoo tshaj plaws: nrog rau qhov ntsuas luv luv ua rau tam sim no txog li 50kA thiab qhov ntsuas tawg tam sim no rau capacitor banks ncav cuag 3150A, nws qhov kev ua tau zoo parameter yog ib qho ntawm cov qib siab tshaj plaws hauv kev lag luam. Txawm hais tias nws yog kev cuam tshuam ntawm cov motors high-voltage, kev ua haujlwm ntawm cov reactors txuas nrog tsheb npav, kev hloov ntawm transformers, lossis cov xwm txheej ua haujlwm nyuaj xws li kev them kab thiab kev hloov pauv tam sim no me me (suav nrog kev hloov pauv tam sim no capacitive, kev hloov pauv shunt reactor, thiab kev hloov pauv tam sim no tsis muaj load transformer), LW36 - 40.5 circuit breaker tswj hwm lawv yooj yim, ua kom muaj kev ua haujlwm ruaj khov ntawm lub zog nrog nws cov kev ua tau zoo txhim khu kev qha. Nrog lub tank SF6 inflatable ua ke nrog lub tshuab tua hluav taws luv luv, nws txhawb nqa kev teeb tsa sai ntawm ob qho tib si kho thiab rho tawm yam tsis tau rhuav tshem lub chamber tua hluav taws arc. Qhov no tso cai rau kev teeb tsa ncaj qha rau hauv cov chaw hloov hluav taws xob uas twb muaj lawm, txo qis lub sijhawm teeb tsa thiab cov nqi zog ua haujlwm, thiab muab kev txhawb nqa zoo rau kev nce qib ntawm cov haujlwm fais fab.
Lub tshuab ua haujlwm caij nplooj ntoos hlav tau tsim los nrog kev ywj pheej thiab kev txawj ntse, txhawb nqa ntau hom kev suav nrog kev tswj chaw taws teeb, kev ua haujlwm hauv zos, thiab kev ua haujlwm thaum muaj xwm txheej ceev. Qhov no ua tau raws li ntau yam kev xav tau siv hauv ntau qhov xwm txheej sib txawv, ua rau kev ua haujlwm yooj yim dua thiab ntse dua.
