Abstract
The invention discloses a utility model of a multifunctional connecting wire for experiment of transformer. The multifunctional connecting wire consists of a common lead for transformer. One end of the lead is connected with the transformer, and the other end is connected with an aviation connector. The aviation connector is also connected with several experimental wires. A connector is connected to the end parts of the experimental wires. The utility model has tight contact structure for preventing fault connection or virtual connection, thus increasing accuracy of the experimental result.
Description
Technical field
The utility model belongs to transformer test wiring technical field, is specifically related to a kind of multi-functional transformer test wiring.
Background technology
Along with the raising day by day of social development and living standard, vast power consumer constantly increases the degree of dependence of electric power, and the power supply reliability of electric system has been proposed requirements at the higher level.For reducing customer outage hours, improve power supply reliability, require electric system to reduce the interruption maintenance test period as much as possible.The electrical performance test project of 220 kilovolts of present stages and above transformer has winding deformation, direct current resistance, carrier wave shape is arranged, low-voltage short-circuit impedance, insulation resistance and Jie decrease pilot project; Personnel need take the bucket arm vehicle wiring; Because various test apparatus interfaces are different; Tested a project, personnel will change primary connection at every turn, and testing a 220KV and above transformer needs 7 hours; Setting up time will spend more than 2 hours, and the power grid security reliability service has been caused certain influence.
Summary of the invention
The purpose of the utility model is the various test connections of transformer are integrated, and testing crew does not need the directly multi-functional transformer test wiring of wiring on transformer when carrying out projects test.
The utility model for realizing the technical scheme that above-mentioned purpose is taked is:
A kind of multi-functional transformer test wiring; Comprise the transformer common lead, wherein: an end of said transformer lead is connected with transformer, and the other end of transformer lead is connected with the aviation head; On the aviation head, also be connected with some test wires, be connected with a joint in the end of test wire.
Wherein outside test wire, be provided with and seal sheath.
The utility model adopts technique scheme; The various test connections of transformer are integrated, it is once gone into the aviation head from transformer, be connected to each test apparatus again through the joint through test wire after the switching of aviation head again by transformer lead; Testing crew does not need directly wiring on transformer when carrying out projects test; Shorten the reverse graft test wire time, reduced the labour intensity of testing crew, increase work efficiency; Secondly simultaneously since the aviation head link order and contact firmly, wrong in the time of can effectively preventing to test, virtual connection and influence test findings have improved accuracy of experimental results greatly.
