1. during laboratory verification current transformer, exactly tested current transformer is compared with standard current transformer
Compared with, it is desirable that standard current transformer and tested current transformer primary side and secondary side polar end are docked.Mutual inductor once, two
Secondary wiring must be by manually completing, and frequent thread-changing is not only time-consuming, but also wiring error easily occurs, and leads to not examine
It surveys.
2. more than position test platform for mutual inductor, more low-voltage current mutual inductors can be examined and determine simultaneously by once flowing up.But high pressure
Current transformer volume is larger, and by verification table space and secondary wiring length limitation, high-tension current inductor can only separate unit progress
Calibrating, no fado platform detect simultaneously, reduce calibrating efficiency.
Utility model content
The purpose of this utility model provides a kind of 10kV and more than current transformer pole aiming at the deficiencies in the prior art
Speed detector, in the process can be automatic in the short period of time complete without manual intervention using this calibrating installation Whole verification
Into improving work efficiency.There is the raising of matter in terms of high-voltage mutual inductor detection speed, can be examined in the time of 3~5 minutes
Survey the high-tension current inductor of 12 any no-load voltage ratios.
The technical solution of the utility model is：A kind of 10kV and more than current transformer rapid testing apparatus, including standard
Current transformer and more tested high-tension current inductors, the more tested high-tension current inductors are put neatly, make it
Secondary side terminal will put a side of more neat tested high-tension current inductors head and the tail successively outwardly, using copper bar
Series winding, when crimping copper bar, the P2 of previous tested high-tension current inductor terminates the P1 of latter tested high-tension current inductor
End is inserted into a side terminal connecting hole with bolt and fastens copper bar, by side terminal lead-out wire folder of standard current transformer
It is crimped on tested high-tension current inductor primary side bolt, the secondary side terminal of standard current transformer passes through detachable extension
Line is connected with the secondary side terminal of tested high-tension current inductor.
The both ends of the copper bar offer once to hold the U-shaped opening being connected with tested high-tension current inductor.
The size of the copper bar connects for 50*5*200mm for adjacent two tested current transformers, and the size of copper bar is
50*5*400mm is for upper and lower two tested current transformer connections.
The bolt uses M8*1.25*71mm coppers bolt copper bar to be reinforced.
The detachable extended line uses 2 meters of long sectional areas as 4mm2Conducting wire.
The utility model is designed reasonably using adjustable copper bar and copper bolt, can be directed to different size mutual inductors, to inspection
Determine device to be transformed, significantly improve calibrating efficiency, solving laboratory verification, time-consuming, and manual intervention is excessive etc. asks
Topic, has the characteristics that safe and reliable, easy to operate, is applicable not only to the interior of 10kV, 20kV and 35kV high-tension current inductor
Calibration operation also has the innovation work of other electric measurements specialty certain promotion and application value.
