Abstract

A self-test auxiliary device and method for visual hardware of a distribution terminal belongs to the technical field of electrical power. The auxiliary device is used for carrying out test wiring of the distribution terminal. A self-test program module is used for automatically complete analog acquisition channel detection, on-off input and output consistency detection, and memory and clock detection for a distribution terminal to be tested. A liquid crystal screen or an LED lamp on the distribution terminal is used for indicating the detection process and the detection result. At the same time, an examination filed is formed and stored in a memory for production technical personnel to consult. For unqualified products, abnormal hardware can be rapidly found according to a self-test file. Periodic self-test of hardware is carried out in the product aging process, the hardware quality problem caused by hardware welding, assembly and the like in the aging process is recorded, automatic testing of distribution terminal hardware is achieved, the test efficiency and the terminal product quality are improved, and the phenomenon that test items are missed due to human factors is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric power, and relates to a data acquisition and control terminal of power distribution equipment in a power grid, in particular to auxiliary equipment and a detection method for power distribution terminal detection.
