KYN61-36 air-insulated metal-clad withdrawable switchgear (hereinafter as switchgear is a kind of MV switchgea r.
It is designed as a withdrawable module type panel, and the withdrawable part is fitted with VD4-36E,VD4-36
withdrawable vacuum circuit breaker manufactured by FARADY Electric Company . It can also be fitted with isolation
truck, PT truck, fuses truck and so on. It is applicable to three phase AC 50/60 Hz power system,and mainly
used for the transmission and distribution of electrical pow er and control,protection,monitoring of the circuit.
Normal Operating Conditions
A. Ambient temperature: -15 40
B. Ambient humidity:
Daily average RH no more than 95%;Monthly average RH no more than 90%
Daily average value of the steam pressure no more than 2.2k Pa, and montly no more than 1.8kPa
C. Altitude no higher than 1000m;
D. The air around without any pollution of duty,smoke,ercode or flammable air,steam or salty fog;
E. External vibration from switchgear and controlgear or land quiver can be neglected;
F. The voltage of the secondary electromagnetism interference induced in the system shall no more than 1.6kV.
Special Operating Conditions
According to IEC60694, GB/T11022, the manufacturer and user may agree on special service conditions whic h
deviate from the normal service conditions.
To prevent the condensation phenomena,the heater is necessary for switchgear and needs to be put into service
when the switchg ear is in readiness and service conditons. The heat dissipation probl em of switchg ear can be
sloved by ventilation facilities.
