The application discloses a cold-pressing connection method for high-voltage outgoing lines and tap switches of a transformer, which comprises the following steps: firstly, determining the wire specifications and the wire quantity to be connected, and determining the tinned copper sleeve specifications; calculating the filling rate according to the wire cross-sectional area and the effective internal area of the tinned copper sleeve, so as to determine the wire quantity to be crimped and the filling wire; performing paint removal treatment on the wire end part to be cold-pressing connected, and the filling wire should be subjected to the paint removal treatment; and cold-pressing the wire by using a cold-pressing tool. The method replaces the existing traditional welding connection mode, the whole operation process is simple, different specifications of the high-voltage outgoing lines and the tap switches of the transformer can be quickly connected, the unique filling mode can ensure the tensile strength and the current-carrying performance of the wire, improves the wiring quality, and greatly improves the production efficiency.

This invention discloses a 135-degree PCB area routing method based on dynamic mesh. First, a serial routing priority queue is constructed to determine the routing order of each net. Then, onboard components and PCB bounding boxes are stored in an obstacle list as basic obstacles for each layer of routing. Next, a dynamic mesh is constructed based on the starting pin position of the net and the obstacles. The constituent elements of the edges in the constructed dynamic mesh are analyzed to obtain the non-obstacle edges. For non-uniform segmentation of channels, the center point of each segment is set as a candidate node for routing and added to the candidate list. An improved heuristic algorithm is used to find the node with the lowest estimated cost. A 135-degree mapping scheme is executed based on the real-time constructed dynamic mesh. Finally, for nets that cannot be extended to the endpoint, a rewiring mechanism is used to adjust existing lines, further improving routing quality.
