Description
Technical field
The present invention relates to a kind of electric relay detection device, belong to relay production field.
Background technology
Relay is generally rated voltage in the design, but in actual use then likely because a variety of causes causes input voltage unstable, relay is made in use usually to access non-rated voltage, generally speaking relay should normally work in rated voltage floats 30% scope, but in the use procedure of reality, relay in process of production some little defects work abnormal when just directly causing relay in rated voltage floats 30% scope, thus other equipment failures of user may be caused, therefore after relay has been produced, be necessary to test relay under different voltage, to see whether it meets pre-provisioning request completely, but for the test of relay in production phase end in prior art, multiple transformer is mainly adopted to carry out multi-point sampler, and such mode and actual use procedure have very big difference, cause relay cannot detect in the floating more abnormal little defects of 30% operated within range of rated voltage.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of electric relay detection device, this electric relay detection device accesses simple test circuit by the voltage device structure of variable output voltage, test relay under effectively ensure that the free voltage that can float in 30% scope in rated voltage, test process fidelity is high.
The present invention is achieved by the following technical programs.
A kind of electric relay detection device provided by the invention, the input of alternating current access transformer, output terminal connecting terminal A, the contact C respectively of transformer, difference connecting terminal B, contact D after another output terminal series connection test circuit, contact A, contact B, contact C, contact D respectively connect a conductive link moved horizontally, and connecting rod is driven by hydraulic pressure or baric systerm can with relay contact pad to be detected; In transformer: secondary winding transformer one end of transformer is connected and fixed the output terminal of terminals as transformer, on secondary winding transformer, cover has movable loop, movable loop is wholely set movable terminals another output terminal as transformer, on movable loop, cover has at least three to roll ring, and movable loop moves on secondary winding transformer by rolling the rotation of ring.

Embodiment
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of electric relay detection device as shown in Figure 1 and Figure 2, the input of alternating current access transformer, output terminal connecting terminal A, the contact C respectively of transformer, difference connecting terminal B, contact D after another output terminal series connection test circuit, contact A, contact B, contact C, contact D respectively connect a conductive link moved horizontally, and connecting rod is driven by hydraulic pressure or baric systerm can with relay contact pad to be detected; In transformer: secondary winding transformer 11 one end of transformer is connected and fixed the output terminal of terminals 12 as transformer, on secondary winding transformer 11, cover has movable loop 22, movable loop 22 is wholely set movable terminals 21 another output terminal as transformer, on movable loop 22, cover has at least three to roll ring 23, and movable loop 22 moves on secondary winding transformer 11 by rolling the rotation of ring 23.
During use, by hydraulic pressure or baric systerm, contact A, contact B, contact C, contact D and relay contact pad can be controlled, can realize testing relay, and by adjusting the position of movable loop 22, can realize testing relay under different voltage.
For convenience of accurate control and the Automated condtrol of movable loop 22 position, the movement of described movable loop 22 on secondary winding transformer 11 is controlled by hydraulic pressure or baric systerm.
As the scheme of robotization, described multiple hydraulic pressure or baric systerm are connected to the unified control of a control circuit.
If relay defectiveness, then when the input of different voltage often circuital current meeting and expectation situation inconsistent, be therefore connected with reometer in described test circuit.
