Problems solved by technology
If the traditional winding method is used, it is easy to cause the primary wire to be knotted, causing the test personnel to spend a lot of time to straighten the primary wire, resulting in a decrease in test efficiency; Serious safety hazards caused by weak connection and disconnection
In addition, during the commutation experiment, the required length of the primary wire changes. Without moving the position of the high-voltage test equipment, it is only necessary to retract the primary wire. At this time, personnel are required to manually retract the wire once. Potential safety hazards of personal electric shock due to high-voltage static electricity retained in the wire
[0003] Therefore, the traditional winding method has problems such as low efficiency and complicated operation.

The invention relates to the technical field of wire take-up and pay-off, in particular to a wire take-up and pay-off device and a high-voltage testing device. The wire take-up and pay-off device comprises a fixing disc body, a wire spool body and a movable handle, wherein the fixing disc body comprises a positioning portion, an installation hole which is in rotating fit with the positioning portion is formed in the wire spool body, a groove for winding a wire is formed in the outer circumferential face of the wire spool body, the movable handle is arranged on the wire spool body, and the movable handle is used for driving the wire spool body to rotate relative to the central axis of the fixing disc body. When the wire take-up and pay-off device performs various kinds of high-voltage testing boosting, wire take-up and pay-off can be conveniently and safely performed by means of a primary wire, the requirement for the complete pay-off length of the boosting wire is met, the damage caused by primary wire take-up and pay-off during boosting is avoided, the high-voltage test safety is ensured, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of wire retraction, in particular to a wire retraction device and high-voltage test equipment. Background technique [0002] At present, when carrying out high-voltage test boosting, multi-strand copper braided soft bare wires with a diameter of 2.5-4mm are generally used as the primary boosting wire, because the height of the high-voltage equipment tested varies (the height difference can reach more than 20 meters) , and in order to meet the requirements of various complex environments on site, it is necessary to prepare a long enough primary wire for high voltage test boost. During the test, due to the different lengths of the primary outlet wires in the high-voltage test boost, the traditional method is to wind and fix the extra primary wires on the uniform ring. If the length is not enough, connect another wire to extend it. If the traditional winding method is used, it is easy to cause the primary wire...
