Technical Advantages And Functional Characteristics

-The product replaces the voltage transformers inside the high-voltage electrical equipment such as the high-voltage power distribution device and high-voltage starter of the 10KV/6KV system of the underground substation, and uses an independent voltage transformer cabinet for the secondary operation of each electrical equipment. Centralized and unified power supply, providing detection power and control power.

-The front door panel of the product is equipped with a display observation window and a 7-inch color display man-machine interface. You can query, set and operate through the front door buttons. The product controls the access and output of the equipment power supply through microcomputer protection, and has early warning functions of power supply switching, overvoltage, undervoltage and zero sequence overvoltage.

-The product can realize the secondary power supply of the high-voltage equipment in this branch, and can switch to another circuit for use when the power supply of this branch needs to be powered off for maintenance.
- The connection between the movement trolley of the product and the isolation fracture of the main circuit adopts the hand-crank method of the ground switch cabinet. When the trolley is inserted, the front door microcomputer window can operate the switch of the power supply of the device. When the PT hand crank of the local machine exits, it will switch to the power supply of the PT trolley of the other machine. When the local PT trolley is inserted, it will return to the local PT power supply to run.
