It is divided into single power supply line and dual power supply network power supply line indicator, single power supply line fault indicator, the design principle is to use the positive current mutation and line power failure to detect the fault point when the line fails, and add a fast detection circuit; For dual-power networked power supply lines, the design principle is based on the current mutation and power direction judgment when the line fails. When the short-circuit moment, the current mutation is greater than a certain value and the same as the set power direction, and the line will soon be affected by the failure. If there is a power failure, the line is considered to be faulty. The control equipment of the motor of the busbar bender machine should be checked and repaired regularly to ensure its normal operation.

The technical condition of the motor control equipment plays a decisive role in the normal starting of the motor. Copper bending machine are widely used in high and low voltage switch cabinets, substations, bus ducts, bridges, electrical switches, communication equipment, household appliances, shipbuilding, office automation equipment, elevator manufacturing, chassis and cabinet manufacturing and other electrical complete manufacturing industries. This machine can be operated according to the limit device on the worktable of the unit during punching and cutting. You can adjust the limit device, and then the workpiece is leaned on the limit device to ensure the punching or cutting size.

 When you are using punching, please punch the reversing handle to the position marked with punching; after punching is completed, punch the handle to the oil return label position. For the single-ended method, in simple terms, it can be boiled down to the iterative method and the method of solving quadratic equations. The iterative method may have false roots, or it may not converge. Although the method of solving quadratic equations is superior to the iterative method in principle and substance, it still has the problem of pseudo-roots. Between multiple rectangular bus bars, a gap not less than the thickness of the bus bar should be maintained. The metal splints (except fasteners) at the end of the bushing for busbars 600A and above should be made of non-magnetic materials, and there should be a metal connection between the busbars and the busbars, and the contact with the copper cutting machine should be stable. The thickness of the metal splints should not be less than 3mm. When there are two or more bus bars, the bus bars themselves should be fixed. The fixing between the busbar fixing hardware and the pillar insulator should be flat and firm, and the busbar supported by it should not be subjected to additional stress. IP20 protective housing is usually used to prevent solid foreign objects with a diameter greater than 12mm and small animals such as rats, snakes, cats, and birds from entering, causing malignant failures such as short-circuit power failures, and providing a safety barrier for live parts.
