Description
Technical field
The utility model relates to the coupling arrangement of a kind of threephase potential transformer tester and test lead, belongs to the electric energy metrical technical field of measurement and test.
Background technology
Existing mutual-inductor tester, Burden box, automatic coupling voltage regulator all adopt the binding post connected mode, need connect 20 leads during calibrating three-phase three element voltage transformer (VT), connect one by one, after examining one by one, could begin test, the shortcoming of this method is a lead connection procedure complexity again, the professional who needs rich experiences finishes, make mistakes easily, in case mistake appears gently then cause equipment damage, and heavy then cause the accident even casualties; Labour intensity is big, and efficient is low.The method of attachment of research threephase potential transformer calibrating installation is to changing above-mentioned situation, and is significant.
The method of attachment of existing threephase potential transformer calibrating installation mainly exists adopts many leads to connect one by one, lead connection procedure complexity, the professional who needs rich experiences finishes, and makes mistakes easily, in case mistake appears gently then cause equipment damage, and heavy then cause the accident even casualties; And the wiring trouble, labour intensity is big, and efficient is low.
Summary of the invention
The purpose of this utility model is that design one cover is simple, uses easily and the threephase potential transformer tester that is difficult for makeing mistakes and the coupling arrangement of test lead, increases work efficiency.
The technical solution of the utility model is, the similar grouping of employing connection lead, lead colour code differentiation on the same group, cable one end adopt aviation plug to concentrate to be connected with equipment, but cable other end employing lock plug divides colour code and equipment interconnection technique, and a kind of coupling arrangement that can satisfy the on-site proving requirement is provided.
Total between threephase potential transformer (TV) calibrating installation inside and device and the test product: boost driving power and stepup transformer, tester and standard TV, tester and test product TV metering winding, Burden box and test product TV metering winding, Burden box and test product TV protection winding amount to 5 set of connections; consider the integrated equipment of tester and Burden box; tester is merged into one group with test product metering winding, Burden box with the lead that is connected of test product metering winding; final formation connects leads for 4 groups, further the connections of simplification device lead.Connect lead and comprise that the driving power lead that boosts, transformer test lead, Burden box connect lead.
The utility model by multi-core cable wire (1), aviation plug (2) but lock plug (3) formed, one end of cable is installed aviation plug, but the other end of cable is installed a plurality of lock plugs, constitute aviation socket one end and can concentrate the equipment of connecing, the private cable connecting line of special-purpose fork, crocodile clip or binding post but lock plug one end can be pegged graft.But the color configuration that the lock plug of described connection heart yearn is pressed the heart yearn crust is the identical color of heart yearn crust therewith, but lock plug divides colour code corresponding connection with equipment, but lock plug has interchangeability flexibly, can with press terminal, each model wiring fork, each model crocodile clip is reliable peg graft after, link to each other with institute survey mutual inductor.
Being connected between threephase potential transformer calibrating installation inside and device and the test product comprises 4 groups of cables, and wherein one group is 8 cores, and three groups is 4 cores; 8 core cables, one termination, 8 core aviation plugs, but the other end 8 cores divide homochromy merging to connect 4 look lock plugs respectively, yellow, green, red, black A, B, C, the N phase line represented respectively; 4 core cables, one termination, 4 core aviation plugs, but the other end 4 cores connect 4 look lock plugs respectively, yellow, green, red, black all connections of representing A, B, C, N phase line, these four groups of cables just can finish the threephase potential transformer calibrating respectively.
The utility model beneficial effect compared with the prior art is that the present invention has following advantage: 1. corresponding equipment of cable, and lead press the corresponding connection of colour code, and is short and sweet; 2. Zhuan Zhi 20 binding posts are replaced by 4 aviation plugs, make the clear attractive in appearance of device panel change, the more important thing is and have improved work efficiency, and effectively avoided the generation of false wiring and accident; 3. but the cable other end adopts lock plug to divide colour code to be connected with equipment, merge into 4 lock plugs but the 8 core leads that device is connected with test product metering winding are homochromy, but lock plug has interchangeability flexibly, can reliably be connected with binding post, each model wiring fork, each model crocodile clip, can adapt to the connected mode of all kinds equipment test product secondary output; 4. workload is verified in the wiring of simplifying greatly after the wiring.The present invention can make the panel of portable threephase potential transformer intelligence testing device of watthour clear attractive in appearance, simplifies the wiring work in the threephase potential transformer verification process greatly, has improved work efficiency, and has effectively avoided the generation of false wiring and accident.
The utility model is applicable to that the threephase potential transformer calibrating detects.
