Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect Understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.

Referring to figure, this utility model provides a kind of technical scheme: a kind of network transformer test fixture, Including base 1, fixing seat 2, test bench 3, sliding seat 4, fixing probe 5 and movable probe 6, Gu Reservation 2, test bench 3 and sliding seat 4 are installed on base 1 successively along base 1 length direction, such as figure Shown in 1, fixing seat 2, test bench 3 and sliding seat 4 are sequentially arranged in base 1, wherein from right to left Fixing seat 2 and test bench 3 are fixedly mounted on base 1, are slidably matched between sliding seat 4 and base 1, And sliding seat 4 can move relative to test bench 3.Fixing probe 5 and movable probe 6 lay respectively at fixing seat 2 and sliding seat 4 on and be relatively fixed with fixing seat 2 and sliding seat 4, test bench 3 has for putting Putting the groove 301 of network transformer, test bench 3 both sides have the instrument connection connected with groove 301 sidewall 302, fixing probe 5 and movable probe 6 insert the instrument connection 302 of test bench 3 both sides respectively, fixing The inner of probe 5 enters in groove 301, and movable probe 6 moves its inner with sliding seat 4 and can pass in and out Groove 301.

The test process of network transformer is, network transformer is put into groove 301, mobile sliding seat 4 make one end (i.e. the inner of movable probe) that movable probe 6 is relative with fixing probe stretch into groove 301 And contact with the stitch of network transformer, the one end simultaneously fixing probe relative with movable probe is (the most fixing The inner of probe) also contact with the stitch of network transformer, and fixing probe and other the one of movable probe End is then connected with test machine by soft winding displacement, test machine carry out the electrical parameter of test network transformator.

This utility model is provided with the drive mechanism driving sliding seat 4 to move, drive mechanism bag on base 1 Including sliding sleeve 701, slide bar 702 and actuator 703, slide bar 702 is joined through sliding sleeve 701 sliding with it Closing, slide bar 702 one end is connected with sliding seat 4, the other end is connected with actuator 703, actuator 703 Slide bar 702 and sliding seat 4 is driven to move.Slide bar 702 is driven to drive sliding seat 4 by actuator 703 And the movable probe 6 in sliding seat 4 moves.
