Abstract
The utility model relates to a device for a CT coil test, comprising at least one unit used for being connected with a CT coil secondary side winding and an experiment instrument, wherein each unit comprises at least one pair of wiring parts used for being connected with a group of secondary side windings of the CT coil and a switch corresponding to the wiring pair; and each pair of wiring parts is connected with the switch corresponding to the wiring part in parallel. The device for the CT coil test is used for solving the problem of needing repeated wiring in the process of the test.
Description
Technical field
The utility model relates to a kind of CT coil test device, belongs to the current transformer field tests.
Background technology
Along with the fast development of electric system, increasing at present to the demand of CT coil, brought the more work amount also for the CT coil test.When CT flowed at once electrification, the necessary short circuit of secondary forbade second open circuit to move.During the CT coil test for enhancing productivity, general a plurality of coil feeds the primary current of regulation together, therefore require to test a coil wherein at every turn, the necessary short circuit of the outlet of other CT coil, same coil has the outlet of many groups during test, therefore except that underproof coil outlet, the also necessary short circuit of remaining coil outlet, this has just caused need be with other coil outlet short circuit when one group of coil is gone out thread test, when another group coil is gone out thread test, need be last group of coil outlet short circuit, this group testing coil disconnects and linking to each other with experimental apparatus then, the problem that wiring repeatedly occurs has influenced test efficiency greatly.
The utility model content
The purpose of this utility model provides a kind of CT coil test device of exempting from wiring repeatedly, is used for solving the problem that present process of the test needs wiring repeatedly.
For achieving the above object, the utility model adopts following technical scheme: a kind of CT coil test device, this device comprises that at least one is used to connect the unit of CT coil secondary winding and experimental apparatus, each unit comprises that at least one pair of is used to connect the wiring part of one group of secondary winding of CT coil and a switch corresponding with this butted line spare, described every butted line spare and the switch in parallel corresponding with it.
Corresponding every butted line spare a pair of incoming end that is used to insert experimental apparatus in parallel in described each unit.
Described wiring part is electrician's clip.
Described switch is normally closed plug-in strip.
The beneficial effects of the utility model are: the utility model adopts a switch to control the short circuit and the disconnection of the outlet of tested CT coil, after testing coil connected, the switch that only need control this group during to that group test gets final product, and need not repeat wiring, has improved conventional efficient.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
In conjunction with Fig. 1 this CT coil test device is described, this device comprises seven unit 1 that are used to connect CT coil secondary winding and experimental apparatus, each unit 1 comprise two pairs of electrician's clips 2, every pair of electrician's clip 2 correspondences two access sides 4 and and a normally closed disconnecting link 3 of every pair of electrician's clip 2 correspondences, every pair of electrician's clip 2 and an access side 4 and normally closed disconnecting link 3 parallel connections corresponding with it.
During test, the outlet of the coil that will be tested earlier connects with electrician's clip 2 successively, when one group of coil of one of them CT coil is gone out thread test, should organize the pairing normally closed plug-in strip 3 of coil outlet opens, experimental apparatus 5 is connect the pairing incoming end 4 of this group coil outlet, during to another group coil test, normally closed disconnecting link 3 closures with last group, the normally closed disconnecting link of this group is opened, experimental apparatus 5 is connect the pairing incoming end of this group coil outlet get final product, in like manner other CT coil is also adopted in a like fashion.
