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 is then possible in actual use because a variety of causes is led
Cause input voltage unstable so that relay usually accesses non-rated voltage in use, it is however generally that relay is in volume
Determine voltage float in the range of 30% should normal work, but during actual use, relay in process of production one
A little small defects work abnormal when just directly resulting in relay in the range of rated voltage floating 30%, so as to cause user
Other equipment failure, therefore after the completion of relay production, it is necessary to he relay is tested under different voltages, to see it
Whether pre-provisioning request, but in the prior art test for relay in production phase Mo are complied fully with, mainly using multiple
Transformer carries out multi-point sampler, and such mode and Shi Jishiyong process have very big difference, cause relay in rated voltage
Some abnormal small defects of 30% operated within range that floats can not be detected.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of electric relay detection device, the electric relay detection device leads to
The voltage device structure for crossing variable output voltage accesses simple test circuit, and 30% model that can be floated in rated voltage has been effectively ensured
Enclose and relay is tested under interior free voltage, test process fidelity is high.
The present invention is achieved by the following technical programs.
A kind of electric relay detection device that the present invention is provided, exchange is electrically accessed transformer input, an output of transformer
Connecting terminal B, contact D respectively after end connecting terminal A, contact C respectively, another output end series connection test circuit, contact A, are touched
The each conductive link that moves horizontally of connection one of point B, contact C, contact D, connecting rod by hydraulic pressure or baric systerm drive can with it is to be detected
Relay contact pad；In transformer：Secondary winding transformer one end of transformer terminals that are connected are used as one of transformer
Be cased with movable loop on output end, secondary winding transformer, movable loop be wholely set movable terminals as transformer another
At least three rolling rings are cased with output end, movable loop, and movable loop can be by rolling the rotation of ring on secondary winding transformer
It is mobile.
The movable loop is moved through hydraulic pressure or baric systerm control on secondary winding transformer.
The multiple hydraulic pressure or baric systerm are connected to a control circuit and are uniformly controlled.
Ammeter is connected with the test circuit.
The beneficial effects of the present invention are：The voltage device structure of variable output voltage accesses simple test circuit, effectively
Ensure that can test relay under the free voltage in the range of rated voltage floating 30%, test process fidelity
Height, and either time cost, space cost or financial cost, are all greatly reduced relative to prior art.

Embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of electric relay detection device as shown in Figure 1 and Figure 2, exchange is electrically accessed transformer input, and one of transformer is defeated
Go out and connecting terminal B, contact D are distinguished after end connecting terminal A, contact C respectively, another output end series connection test circuit, contact A,
The each conductive link that moves horizontally of connection one of contact B, contact C, contact D, connecting rod by hydraulic pressure or baric systerm drive can with it is to be checked
The relay contact pad of survey；In transformer：One end of secondary winding transformer 11 of transformer is connected terminals 12 as transformer
An output end, be cased with movable loop 22 on secondary winding transformer 11, movable loop 22 has been wholely set the movable conduct of terminals 21
At least three rolling rings 23 are cased with another output end of transformer, movable loop 22, and movable loop 22 can be by rolling ring
23 rotation and moved on secondary winding transformer 11.
In use, by hydraulic pressure or baric systerm, controllable contact A, contact B, contact C, contact D and relay contact connect
Touch, you can realization is tested relay, and by adjusting the position of movable loop 22, you can it is right under different voltages to realize
Relay is tested.
Accurate control and Automated condtrol for convenience of the position of movable loop 22, the movable loop 22 is in secondary winding transformer 11
On be moved through hydraulic pressure or baric systerm control.
As the scheme of automation, the multiple hydraulic pressure or baric systerm are connected to a control circuit and are uniformly controlled.
If relay is defective, the often circuital current meeting and it is expected that situation is inconsistent in different control sources, because
Ammeter is connected with this described test circuit.
