Automatic Recloser Controller ngadto sa Cebuano: Awtomatikong Pagsarado nga Tagapamahala

Mga Pahayag

Ang RWK-35 usa ka intelligent medium Voltage controller nga gigamit sa overhead line grid monitoring aron maprotektahan ang overhead line. Kini mahimong pagbutangan og CW(VB) type vacuum circuit breaker aron maabot ang automatic monitoring, fault analysis ug store event records.

Kini nga yunit naghatag og safe line switching sa mga fault sa power grid ug naghatag og automatic power recovery. Ang serye sa RWK-35 kuyog sa hangtod sa 35kV outdoor switchgear sama sa vacuum circuit breakers, oil circuit breakers, ug gas circuit breakers. Ang RWK-35 intelligent controller gipakompleto ngadto sa line protection, control, measurement, ug monitoring sa Voltage ug current signals nga integrated automation ug control devices sa labas.

Ang RWK usa ka automatic management unit para sa single way/multi ways/ring network/two power sourcing, na-provide og tanang Voltage ug current signals ug tanang function. Ang RWK-35 column switch intelligent controller nagsuporta sa: Wireless (GSM/GPRS/CDMA), Ethernet mode, WIFI, optical fiber, power line carrier, RS232/485, RJ45, ug uban pang form sa communication, ug makapuyo sa uban nga station premises equipment (tulad ni TTU, FTU, DTU, etc.).

Q: Ano ang recloser?

A: Ang reclosing device usa ka device nga makakita sa automatic detection sa fault current, ug automatic cut off sa circuit kon may fault, ug paghuman perform multiple reclosing operations.

Q: Ano ang function sa recloser?

A: Ginagamit kini sa distribution network. Kon may temporary fault sa line (tulad sa branch touching the line for a short time), ang reclosing device restores power supply pinaagi sa reclosing operation, nga dako kaayo nakatabang sa pagreduce sa outage time ug scope ug nag-improve sa power supply reliability.

Q: Asa ang recloser magdetermine sa type sa failure?

A: Ini monitor nia ang characteristics sama sa magnitude ug duration sa fault currents. Kon permanent ang fault, human sa preset number of reclosing, ang reclosing device will be locked aron iwasan ang further damage sa device.

Q: Asa ang application scenarios sa reclosers?

A: Widespread kini gamiton sa urban distribution network ug rural power supply network, nga effective cope sa various possible line failures ug ensure stable supply of power.
