【 摘 要 】

The main technical indicators of high-current output equipment include current amplitude magnitude, current output accuracy, current carrying capacity, current rise time parameters, harmonic output capability and other technical indicators, among which the carrying capacity is an important technical indicator of current output. . When the substation on-site equipment is tested, the on-site test cable is long and the load impedance is large. This imposes a high requirement on the carrying capacity of large-current devices. With the connection mode and external load unchanged, the load capacity of high-current devices is increased. The technical requirements and production difficulty of the equipment are greatly increased, and the overall weight and volume of the high-current equipment are also increased, which increases the difficulty of on-site testing of the high-current equipment. This article mainly discusses a test method for improving the carrying capacity of high-current devices. By changing the test method, the load carrying capacity of the device can be improved, and the difficulties in making high-current devices and the difficulty of on-site testing can be reduced.
