Analysis Of High-voltage Disconnector Wiring: A Reverse-flow Fire Layout Explanation
Date: | Read: 5
High Voltage Disconnect Switch is typically used in electrical cabinets to disconnect or connect circuits, and its contact configuration determines the connection method for each circuit. Generally, the stationary contact is connected to the power supply side, and the moving contact is connected to the load side. However, when using cable entry in the receiving cabinet, the power supply end is reversed to the moving contact side, forming a so-called "reverse-entry" connection. This wiring method is more common in cable entry conditions, facilitating the internal wiring layout of the cabinet to correspond with the busbar direction.
