Case Study: Customer Specials/Layout
Industrial Medium Voltage Switchgear
Objective: Build 10kV switchgear to customer specification
Standard Breakers
| |
| A series of standard breakers are designed in 3D
|
Standard Cabinet Design
| | |
| A range of 5 cabinets
| |
| Standard cabinet designed in 3D
| |
| Cabinet unfolded using Sheet Metal
|
Custom Electrical Protection
| | |
| Dependent on electrical load
| |
| Dependencies from other breakers
| |
| Significant electrical design content
| |
| A variable number of components to mount on each cabinet door
| |
| The customer always has the final say on the layout of each door
| |
| The design of the door occurs in the last day or two before production, due to time needed to get agreement from the customer on electrical design
|
Challenge: To lay out the equipment selected by the designers on the unfolded door, agree it with the customer, and then produce door.
Solution: Produce door layout in 2D with STHENO/PRO, and automatically punch door
| | |
| A list of all components required is produced from the B.O.M. output of the electrical system
| |
| A tool is provided to select the appropriate symbol for a part directly from the B.O.M.
| |
| The designer lays out the door to the customer's requirements, regularly e-mailing the customer a drawing for agreement
| |
| The labelling is automatically added to the symbols from the electrical B.O.M.
| |
| The cut-outs for the components are in the symbols on a special layer
| |
| The outline of the door, derived from 3D, is automatically merged with the 2D component layer and CNC punch data automatically produced
|
From approval of design to manufacture in a few minutes!
Benefit: The manufacturer is building a custom product at least as efficiently as other companies build standard products, but at a premium price.
