On-site uninterruptible power supply automatic test method for on-site feeder automation switch terminal

The invention discloses an on-site uninterruptible power supply automatic test method for an on-site feeder automation switch terminal, and relates to the technical field of distribution automation. The on-site uninterruptible power supply automatic test method for an on-site feeder automation switch terminal is suitable for on-site automatic test of on-site feeder automation equipment such as a voltage-time type, a voltage-current time type, a national grid adaptive type, a voltage-current time + relay protection type and a closing quick-break type. The on-site uninterruptible power supply automatic test method for an on-site feeder automation switch terminal uses a feeder automatic intelligent tester with a programmable function and a feeder condition switch adaptive simulator to complete the automatic test of the related functions and technical indicators of a power distribution switch terminal during the overall process of fault occurrence, fault judgment, fault isolation and non-faulty area power restoration for the fault occurrence position in various situations, such as the upstream, the downstream and irrelevant branches of the tested power distribution switch terminal under the transient fault and permanent fault conditions for one time when the tested switch device is running normally without power failure, at the same time, automatically generates a test report, andcan store, output or upload the test report to a cloud platform.
