Description
Technical field
The present invention relates to a kind of CPCI type high voltage relay modules for Insulation test and continuity test, are mainly used for
It builds with the passive continuity test of cpci bus structural framing and Insulation test automatic test equipment, realizes the nothing to test product
The automatic test of source conducting and the automatic test of insulation.
Background technology
Cable, it is automatically controlled when electric products production, check and accept when, need carry out insulation performance inspection, i.e., two insulation survey
Between pilot apply one compared with High Level DC Voltage, then measure its insulation resistance resistance value whether meet product specification requirement.Conventional measurement
Method for testing is to carry out Insulation test between any two to insulation tested point, is tested if necessary to carry out insulation performance two-by-two to N number of point,
It then needs to measureSecondary, the test method testing time is longer, causes the testing time longer.The present invention passes through hardware design reality
Now single point-to-multipoint Insulation test if carrying out insulation performance test to N number of point, wherein will be connected to insulation by i-th of tested point
The "+" end of test pencil, and other N-1 point is shorted to the "-" end of insulation test pencil, then it only needs whole insulation to can be realized N-1 times
Test.
In addition, the higher DC break down voltage value of the relay needs of tested point switching in Insulation test, and mainstream in market
CPCI type relay module does not have high pressure resistant property mostly, and have in the CPCI type relay module of high pressure resistant property after
Electric appliance number is again very little, and veneer is difficult to the requirement for meeting multiple spot testing insulation between plates and continuity test versatility, CPCI of the invention
Type high voltage relay module efficiently solves high pressure resistant and veneer poor universality deficiency.
Tested point is divided into three classes：(1) it had not only needed continuity test but also had needed the tested point of Insulation test, hereinafter referred A classes are treated
Measuring point；(2) tested point of continuity test, hereinafter referred B class tested points are only needed；(3) tested point of Insulation test is only needed, under
Literary abbreviation C class tested points.
Invention content
The technology of the present invention solves the problems, such as：Overcome tradition the Insulation test testing time be long two-by-two, veneer is not high pressure resistant and
The poor deficiency of veneer versatility provides a kind of for Insulation test and the CPCI type high voltage relay moulds of continuity test
Block.
The present invention technical solution be：A kind of CPCI type high voltage relays for being used for Insulation test and continuity test
