Structural features:
1.Framework using 8 mf type opening sections, installed on the main frame modulus is E = 20 mm and 100 mm Φ 9.2 mm of mounting holes, making flexible frame assembly.
2.The function rooms of the switch cabinet are isolated from each other, and the compartments are divided into functional unit rooms, bus rooms and cable rooms.The function of each chamber is relatively independent.
3.The horizontal busbar adopts the way of horizontal arrangement behind the cabinet to enhance the ability of the busbar to resist electric power.
4.The design of the cable compartment makes it very convenient to go in and out of the cable.
5.The module of drawer height is 160mm.Drawer changes change on height dimension only, its width, depth dimension is changeless.Drawers of the same functional unit have good interchangeability.Rated current of unit loop 400A and below.
6.Drawer panel with division, close, test, pull out the obvious mark of the position.The drawer unit is provided with a mechanical interlock.Drawer unit as the main body, at the same time with draw - out and fixed, can be mixed combination, arbitrary use.
7.The protection grade of cabinet body is IP30 IP40, still can choose according to user need.
Conditions of use
1.For indoor use, the elevation of the service point shall not exceed 2000m.
2.The ambient air temperature is no higher than +40 degrees and no lower than -5 degrees.The average temperature should not be higher than +35 degrees within 24 hours.When exceeding, the capacity should be reduced according to the actual situation.
3.The relative high temperature of the surrounding air is +40 ° c and does not exceed 50%.If +20 degrees is 90%, consideration should be given to the effect of occasional condensation caused by temperature changes.
4.When the device is installed, the tilt with the vertical plane shall not exceed 5°, and the whole set of cabinets shall be relatively flat in line with the standard of gbj232-2.
5.The device shall be installed in a place free from violent vibration and shock and where the electrical components are not sufficiently corroded for use
