Armored Removable AC Metal-enclosed Switchgear
Switchgear structure (see Figure 1).
Completely metal armored,assembled structure,wide combination solution.
● The cabinet body is made of imported aluminum and zinc coated thin steel plate,processed by MINGE machine tool,adopting advanced multi-edge folding technology,connected with rivet nuts and high-strength bolts,with high precision,lightweight,high strength and strong versatility of parts.
● lt can be equipped with VS1-24 series or imported VD4 series vacuum circuit breaker,with wide applicabiity,high reliability and long maintenance free years.
● The handcart is equipped with working and testing positions,and each position is equipped with positioning and display devices, which is safe and reliable.
● All kinds of handcarts can be changed according to modular building blocks,ensuring that handcart of the same specipcation can be freely interchangeable,and handcart of different specipcations can never enter.
● Ground switch installation mode
a.Installed in the middle part of the cabinet (front-mounted type)for convenience of double-sided maintenance of the cabinet.
b.Installed at the back of the cabinet (rear type)to save space against the wall.
● Current transformer installation method:
a.Installed in the front of cable room at the back of cabinet.
b.Hoisted at the bottom of large bending plate.
● Up to 9 single-core cables can be installed in the cable room.
● Each high pressure room has a pressure relief channel to ensure personal safety.
● Highly reliable interlocking device fully meets the safety requirements of "five-prevention".
● The handcart is transported by special truck,which is light and ßexible in operation.
● The front and back doors are equipped with observation windows,which can easily observe the working status of indoor components.
