The basic frame of this series of products is assembled and assembled. All the components of the cabinet are connected to each other by screw fastening to the basic frame. Then, if necessary, add doors, baffles, partitions, drawers, mounting brackets, and parts such as busbars and electrical components. , assembled into a complete switchgear, this cabinet has the following advantages:
1. The frame is made of C-shaped profile, which is positioned by three-dimensional gusset. The self-tapping stud is connected with no welded structure to avoid welding deformation and stress and improve the installation accuracy.
2. The mounting holes of the cabinet and parts are changed according to the modulus ^25 (TM).
3. The internal structural parts are forged and cast. External pickling and phosphating
After treatment, it is sprayed with electrostatic epoxy powder.
4. In the power center (PC) inlet cabinet, the top is the horizontal bus area
In the domain, the lower part of the horizontal busbar area is the circuit breaker room. The circuit breaker can be equipped with various circuit breakers produced by foreign electric companies, such as E-system 歹IJ produced by ABB, MT series produced by Schneider of France or SIMEN produced by Germany. 3WN6 series circuit breakers, as well as intelligent circuit breakers.
