Operating conditions

1. Ambient air temperature: -15℃ ~+40℃
Daily average temperature: ≤35℃
When the actual temperature exceed the range, it should be used by reducing the
capacity accordingly.
2. Altitude: ≤2000m
3. Relative humidity: ≤50%, when temperature is +40℃
When temperature is low, larger relative humidity is allowed. when it is +20℃,
relative humidity can be 90%. Since the temperature change will make out
condensation.
4. Installation inclination: ≤5%
5. Applicable in the places without corrosive and flammable gas.
Note: Customized products are available.

Features

1. C type material adopted for the mainframe, frame use the form of Assembling structure. Main frame have the installation modular hole E=20mm
2. The Compartment is divided into functional unit rooms, bus room, cable rooms,Each unit is relatively independent .”
3. Take the drawer as main body, meanwhile have the draw out type and fixed type, can mixed combination, Arbitrary selection.

4. Cabinet size (refer to sheet 2)                                                                                                                                                                                                 Sheet 2

5. Functional unit
1) The higher modulus of drawer is 160mm, divide to1/2 unit, 1 unit, 1.5unit, 2 unit,3 unit 5 different size series. Unit loop rated voltage below 400A.
2) The same functional unit of the drawer has good interchangeability.Each MCC cabinet can install max 11 set drawer with 1 unit, or 3) 22 sets drawer with 1/2 unit. Drawer with more than 1 unit adopt multi-functional plate .
4) Drawer incoming and outgoing line adopt the same standardized plug of slice structure with different quantity according to current 5) The transfer between ½ unit drawer and cable cabinet use ZJ-2 adapter..
6) The transfer between drawer which is above 1 unit and cable cabinet use standardized bar type or tube type ZJ-1 adapter according to different current rated.
7) Drawer panel have the open, close, test, draw out position indicator.
8) Drawer unit have Mechanical linkage.
9) Feeder cabinet and motor control cabinet have special cable insulation cabinet. The connection between functional unit and cable cabinet adopt adapter.Not only improves the reliability of the cable, and greatly facilitates the user safety and repair of cable.

6. Busbar
In order to improve the bus dynamic thermal stability and improved contact surface temperature rise, device use TMY-T2 series of hard copper, Copper plate surface will be treated with new advanced oxidation process. The performance index is superior to the traditional tin plating process.
1) Horizontal busbar
Horizontal busbar is arranged in Busbar compartment at the back of cabinet,double busbar for above 2500 A, single layer busbar for current below 2500A.Each phase is composed of 4 or 2 pcs busbar ,improve the Short circuit strength of bus.
2) Vertical bus
"L" shape hard copper tin bus is used for vertical busbar of drawer.L type bus specification(mm):
(Height ×thickness)+(button×Thickness)(50 ×5)+(30 ×5)Rated current 1000A
Neutral grounding busbar
3) Adopt hard copper. Through the level of neutral grounding wire (PEN) or ground +neutral line (PE+N).
