Intelligent indoor low voltage electric substation equipment
1)main function:
1:power distribution control cabinet for power generation and supply system
2:centralized control of motor
3:reactive power compensation at same time
2)suitable place
1: all places where required high reliability and safe power distribution and motor control.
2 :for rated working voltage380V- 660V electric system
3:successfully widely used by national engineering designing institute, mining company, cement mill, stell mill,sugar factory,wood industry, chemical industry, city planning, high building, light industry, commucial center,etc
3)cabinet characteristic
It is top world level technique ,high intelligent assemble way, easy operation and maintenance
1:all component are standard type, conveninet for project planning
2:drawer can be built up into different modes freely
3:The frame of the cabinet selects tee bend connection of 25mm modulus special C section bar, which is assembled by locking screws and high strength screws.
4:The cabinet body is made of cold rolled steel or imported A-zinc alloy plates
5:the equipment is with function :Anti electric arc ,earthquick resistance, oscillation reistance, shock reistance
6:The cabinet body is free of maintenance to most extent
4)drawer function:
1:each drawer is independent, and seperated entirely, and each one can exchange internally
2:the drawer is contained of several engine function parts, it has place with CONNECTION/ TEST/ SEPERATE/ MOVE OUT ., and can locked seperately. the display/ control/ human-machine face to face panel are centralized in front board
3:through hand shank and interlock, can accurately fix postion in CONNECTION/ TEST/ SEPERATE/ MOVE OUT . each position will show directly on front panel
