Specify how voltage values ​​relate to copper in orCAD
How to lay copper in orCAD (1)Shape/Polygon (2) Option column setting 1) class and subclass 2) Dynamic copper dynamic positive film type copper, will automatically hollow out Static Solid static solid Static crosshatch static grid, does not automatically dig to avoid Unfilled means static unfilled shape, suitable for drawing board outline, package geometry, room, etc., the electrical layer can not add this type of shape 3) Assign net name, click the expand button, select the network to give the network name or directly enter the network name, OK Note : Voltage values ​​must be specified when assigning power attributes to the network. Logic/Identify DC Nets, such as Gnd voltage is 0 Segment type indicates the line type when drawing the boundary (valid when Polygon is selected) Line represents a straight line in any direction Line 45 indicates a corner of 45 degrees Line Orthogonal is expressed as a right angle Arc represents an arc (3) Copper , drag the mouse in the work area to draw graphics, right click, Done (4) Editing the copper boundary Shape/Edit Boundary or click on the icon Option column Segment type select Line Orthogonal Click on the target copper, Click on the copper border and drag the mouse to draw a new border. Right click, Toggle changes direction The end of the line is also on the boundary Note : The end of the line must be a point on the boundary, otherwise it cannot be placed. If the copper is drawn, the network name is not specified. (1)Shape/Select Shape or Void(Cavity) (2) Select copper, right click, Assign Net (3) In the Option column, assign net name, click the expand button, select the network (4) Right click on the work area, Done completes the operation, the above is the operation process of copper plating .

2. Impedance transformation function: increase the system impedance, so that the protection device can be easily matched;
3. Function of stabilizing system voltage: for example, when starting heavy load equipment, reduce the impact on system voltage;
4. Function of preventing system grounding: when single-phase grounding occurs on the load side of the isolation transformer, it will not cause single-phase grounding of the whole system (above the Satons isolation transformer);
5. Reduce short circuit current: limit the short circuit current of the system when a short circuit accident occurs on the load side.
DG (B) /BK series single-phase isolation transformer can not only change the voltage, but also electrically isolate the input winding and output winding from each other, so as to avoid the danger caused by touching electrified body (or metal parts that may be electrified due to insulation damage) and ground at the same time. In addition, the isolation transformer also has the function of restraining various inter ferences.
