Abstract

The invention relates to a special-purposed power test wire plug and a test method thereof. At present, test cannot satisfy a plug-and-play function when DDC test wires are used, a connecting wire is needed, and the working efficiency is influenced. The plug is characterized by comprising a plug conduction joint, a magnetic ring, a plug bushing, a conductive spring, a plug pedestal and a stop block, the plug pedestal is fixed at one end of the plug bushing, the magnetic ring is fixed at the other end of the plug bushing, the stop block is positioned in the plug bushing, the diameter of the stop block is greater than the internal diameter of the magnetic ring, the plug conduction joint is fixed at the top of the stop block, the conductive spring is placed in the plug bushing, one end of the conductive spring abuts against the plug pedestal, and the other end of the conductive spring abuts against the bottom of the stop block. According to the invention, a fastening screw of a terminal row is connected tightly via a magnetic force, so that a contactor part of the plug is reliably connected with the fastening screw of the terminal row, an internal loop of the terminal row is connected with an external loop which is connected with the plug, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a special electric power test line plug and a test method. Background technique [0002] When developing, testing, testing, and maintaining power and electrical secondary equipment (generator-transformer protection devices, fault recorders, and excitation, etc.), power test lines are often used to apply current, voltage, or short-circuit to the terminals of the equipment. terminals. At present, DDC test lines are basically used. There are elastic steel wires around the test line plugs, or elastic steel sheets are connected to the terminal blocks. Some current terminal blocks can be plugged and played. For a small number of current terminals, the test cannot meet the plug-and-play function and requires the use of connecting wires. The workload is relatively large during the test process, which affects work efficiency. For example, in the Chinese patent whose publication date is December 24, 2008 and whose publication number is...
