The main function of Current transformer core is to change a large current into a small current suitable for electrical measuring instruments and relay protection. In the high-voltage system, Current transformer core isolates the current loops of electrical instruments and relays from the high-voltage conductive loops to ensure the safety of measuring instruments and relays, and to ensure personal safety when working on measuring instruments and relay protection.
Current transformer core Open circuit operation is not allowed on the secondary side. If the secondary side of Current transformer core is open, the magnetic flux in the iron core increases sharply with the increase of the primary current, which not only causes serious saturation of the iron core, but also induces a high voltage on the secondary side, which will seriously harm the insulation of the secondary circuit. , Even breakdown and burn out; at this time, if someone touches the secondary circuit, it is easy to cause electric shock injury.
Current transformer core When the secondary side is open, not only is the high voltage induced on the secondary side due to the large value of the magnetic flux in the iron core, but also due to the saturation of the iron core, the slope of the curve of the magnetic induction intensity increases, causing the secondary side induced electromotive force to appear very high. The peak wave, its voltage amplitude can reach a dangerous value of 2-3KV. Therefore Current transformer core does not allow secondary open circuit during operation.
