12kV Switchgear KYN28A-12
KYN28A-12 air-insulated metal-clad enclosed switchgear is a necessary power distribution
equipment in 7.2~12kV 3-phase AC50/60Hz single busbar sectional power system.
It is major used in power generator, substation,
factory and high building to receive and distribute electrical power. Also it is used to control,
protect and monitor the circuit. The switchgear accords with the standard of GB3906, DL/T404 and so on.
■Characteristic:
● Completely metal-clad and enclosed, prevent the accident spreading.
The low voltage section and the high voltage section are full individual.
● The protection degree with the door closed is up to IP4X.
It prevents persons and outside solid approaching the live part and withdrawable part,
ensuing persons safe and the switchgear operated reliably.
● Install and maintain conveniently with the cable compartment enough space.
● The interlocks are simple and reliable and prevent maroperation effectively.
● Equipped with advanced relay-protecting device and can realize the power system automatically.
● Full assembled structure, handsome figure and high precision process.
● The switchgear installed against wall is maintained in the front;
double-side maintenance is convenient and reliable.
● There are pressure relief passages in the trolley compartment,
busbar compartment and cable compartment.
Thus ensure persons safely and prevent accident spreading when electrical arc occurs due to fault
■ Normal use condition
● Ambient air temperature:maximum temperature+40 ℃, minimum temperature -15℃.
● Humidity condition:daily average relative humidity: ≤95, daily average vapor pressure shall not exceed 2.2Kpa;
Monthly average relative humidity: ≤90?, Monthly average vapor pressure shall not exceed 1.8Kpa
● Altitude:Below 3000m.
● Earthquake intensity:Lower than 8 degrees.
● The ambient ait shall not be polluted by distinctive corrosive ot conbustble gas, vaporetc.
● Places free of frequent excessive vibrations.
● The user shall negotiate with manufacturer if the equipment is used beyond the normal conditions described in GB3906.
■ Design featuers
● Switch gear structure plesse see to figurel.
● Entirely metal armored, assembly structure, wide range of assembly schemes.
● The cabinet body adopts importes aluminized and galvanized sheet , which is prossed
