Switchgear Tegangan Tinggi (KYN28-12)

KYN28-12 High-voltage Switchgear is a kind of metal-sealed, sheathed, moving-away-style, indoor switchgear, for three-phase single bus-bar and bus-bar subsection systems of exchange frequency 50 Hz, rated voltage 3-10 KV, rated power below 3000A for acceptance and distribution of electric energy. This switchgear has complete five-protection devices, and meets the requirements of all types of power plants, substations and industrial and mining enterprises.

KYN28-12 high-voltage Switchgear is the metal-sealed, sheathed, moving-away-style, indoor switchgear. Switchgear body is made of bending steel board plated with aluminum zinc, it is an entire enclosed structure, devidied into four parts with steel board inside and bolt-linked, the top for bus-bar, the middle for handcart, the lower for cable part. Meters and relays are installed in the instrument room in front of the top part, with function lifting overhead the wires in and out and connecting both sides.

Handcart is welded by angle steel and steel board, divided into circuit breaker handcart, voltage transformer arrester handcart, capacitors arrester handcart, using transformers handcart, separation handcart, earth handcart and so on. The panel of handcart is the door of switchgear, and observation window and lights are on the top of the door which can lock the handcarf in working place, testing place and separating place.

A chain is installed on the top and below of the door at the back, We can open the lower door and then open the top door bihind only after drawing out the handcarf when power off and earthing switch grounded. The earthing switch will be separated only after closing the top door behind and then closing the lower door, so that the handcart can be inserted into the work place to prevent from entering with power on.
