Nakaradduka:
Gas Insulated Switchgear (GIS) shine mahaɗin daɗi na 3-phase AC tsohon kofin kula da aka faɗa don inganci, kiyaye, haɗaƙarwa, da kuma gudanar da hanyoyin kungiyar. Daga cikin zaka 5,000 baya da aka fitowa a duniya, an fitar da shi a kasashen kamar Tajaniya da Guinea Tsohon Gini, wanda ya fi yin abin daɗi a duniya.
ZF12B -72.5/126/145 (L) GIS ya ɗauke masu muhimmanci na substation, sama da circuit breakers, disconnectors, earthing switches, voltage transformers, current transformers, da surge arresters. An gina shi da layout ta ɗaya enclosure, da take tsara funsamiyar. A matsayin hasashe, ɗan ɗaukan DS/ES (disconnector/earthing switch) na 3-working-position tana ba da tsarin mai kyau, wanda ya bayyana aiki mai kyau da kuma tsari mai kyau.
Abubuwan Da Yawa:
Tsarin Mai Kyau: Ɗan ɗaukan DS/ES na 3-working-position tana ba da tsari mai kyau, ƙwarewa, physical mechanical interlocks, da kuma inganci, wanda ya taimaka waɗannan da suka amfani da shi don samun aiki da kalmomin kanta.

Parametolin Teknikalai:
Koda da ɗan ɗaukan protection function na gas-insulated switchgear?
Principles of Protection Function:
GIS equipment is equipped with various protection functions to ensure the safe operation of the power system.
Overcurrent Protection:
The overcurrent protection function monitors the current in the circuit using current transformers. When the current exceeds a predefined threshold, the protection device triggers the circuit breaker to trip, cutting off the faulty circuit and preventing damage to the equipment due to overcurrent.
Short-Circuit Protection:
The short-circuit protection function quickly detects short-circuit currents when a short-circuit fault occurs in the system and causes the circuit breaker to act rapidly, protecting the power system from damage.
Additional Protection Functions:
Other protection functions, such as ground fault protection and overvoltage protection, are also included. These protection functions use appropriate sensors to monitor electrical parameters. Once any abnormality is detected, the protection actions are immediately initiated to ensure the safety of the power system and equipment.
