Abstract

The invention relates to a full-automatic low-voltage current transformer testing wiring apparatus comprising main transmission shafts, a driving wheel, a fixed baffle plate, a power source and a transmission mechanism. Two main transmission shafts are arranged in parallel in an insulated housing; the driving wheel is installed below the two main transmission shafts that are driven simultaneously by the driving wheel; and the driving wheel is connected with the power source by the transmission mechanism. A plurality of stand columns are arranged at the main transmission shafts; bar-shaped holes are arranged at the insulated housing, wherein the number of the bar-shaped holes is identical with that of the stand columns; the stand columns are extended out of the insulated housing through the insulated housing; and the fixed baffle plate is arranged at one side of the bar-shaped holes. One ends of the springs are fixed at the stand columns and the other ends of the springs are connected with testing contacts; the testing contacts, the springs, the stand columns and the main transmission shafts are connected with each other by a mutual insulated way; and the testing contacts and the testing outgoing lines are connected by a conductive way. According to the invention, the provided apparatus has the advantages of having high automation degree, having good reliability, being free of polarity determination, short-circuit and open-circuit phenomena, and carrying out wire removing process simply.

Description

technical field [0001] The invention relates to a test wiring device for a transformer, in particular to a fully automatic low-voltage current transformer test wiring device. Background technique [0002] The current calibration method of manual wiring uses metal test wire clips to connect with the secondary circular metal terminals of the transformer. In this way, the test wire clip is very easy to fall off, resulting in an open circuit. At the same time, due to the loose connection, the metal head of the wire clip slides, causing a short circuit. In the event of poor contact, wrong connection of test line clips, reversed polarity, etc., the entire calibration work will be interrupted, and the calibration can only be restarted after re-inspection and approval. At the same time, the test wires are entangled with each other after the wires are removed, causing trouble and confusion for the next calibration. Contents of the invention [0003] In order to overcome the probl...
