Description
Technical field
One kind is the utility model is related to be avoided that because electronic component breaks down so as to cause due protective device not
Action causes equipment and the industrial frequency withstand voltage test device of personal injury.
Background technology
The overcurrent protection of conventional industrial frequency withstand voltage test device is typically all to the electric current in circuit by current measuring device
Sampled；When collecting current signal and reaching over-current adjusting value, protective device acts, and disconnects industrial frequency withstand voltage test device
Power supply, to realize overcurrent protection function.During use, when electronic component breaks down because of various reasons so as to cause to protect
Device is not operating to cause equipment and human casualty accident.We have developed one kind be avoided that because electronic component break down so as to
Cause due protective device is not operating to cause equipment and the industrial frequency withstand voltage test device of personal injury.
Utility model content
The utility model aim is to provide one kind for overcome the deficiencies in the prior art and be avoided that because electronic component is sent out
Raw failure is so as to cause due protective device is not operating to cause equipment and the industrial frequency withstand voltage test device of personal injury.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of industrial frequency withstand voltage test device, including examination
Test change, divider and console；The experiment becomes and divider is electrically connected；The experiment becomes to be electrically connected with test item；Described point
Depressor is in parallel with test item；The console and experiment are electrically connected with electric current relay between becoming；The normally closed of electric current relay is touched
Point connects the spare opened point of console；The normally-closed contact of electric current relay is changed to the separating brake line of normally opened signal access input switch cabinet
Circle；The ground terminal and high pressure tail end that electric current relay access experiment becomes；The input termination test circuit that the experiment becomes；Work as test
When electric current in circuit exceedes over-current adjusting value, the normally-closed contact closure of electric current relay, console control test circuit disconnects.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Industrial frequency withstand voltage test device described in the utility model is avoided that because electronic component breaks down so as to cause to answer
Some protective devices are not operating to cause equipment and personal injury.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is the fundamental diagram of industrial frequency withstand voltage test device described in the utility model.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Attached drawing 1 is industrial frequency withstand voltage test device described in the utility model, including experiment change, divider and console；Institute
Experiment is stated to become and divider electrical connection；The experiment becomes to be electrically connected with test item；The divider is in parallel with test item；The control
Platform processed and experiment are electrically connected with electric current relay between becoming；The normally-closed contact of electric current relay connects the spare opened point of console；Will
The normally-closed contact of electric current relay is changed to the switching winding of normally opened signal access input switch cabinet；Electric current relay access experiment becomes
Ground terminal and high pressure tail end；The input termination test circuit that the experiment becomes；When the electric current in test circuit is whole more than overcurrent
During definite value, the normally-closed contact of electric current relay disconnects, and console control test circuit disconnects.
In the present embodiment, the normally-closed contact of electric current relay connects the spare opened point 37 of console, and 38, and normally closed signal is changed
The switching winding of input switch cabinet is accessed for normally opened signal.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Industrial frequency withstand voltage test device described in the utility model is avoided that because electronic component breaks down so as to cause to answer
Some protective devices are not operating to cause equipment and personal injury.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
