Full-automatic multiloop secondary cable Insulation test servicing unit described in the utility model, by all cores of cable under test
Line with test wire terminal be connected after be connected to again on aviation plug, last cut-in relay, insulation tester p-wire also access after
Electrical equipment, by the way that cpu controller is single-chip microcomputer control relay connection point on-off to realize Insulation test changing-over line.The utility model is only
Need to be by after all cored wires disposably full access device, follow-up test is automatically finished, and the insulation of each cored wire can be surveyed simultaneously
Examination, the cable of either several cores, detection used time need to only disconnect the line average used time plus the measurement average used time, realize that overall shorten is surveyed
Try the target of time；The disposable whole access devices of all cable cores, something lost caused by artificial single line core is respectively connected to can be eliminated
Possibility is leaked, avoids test leakage.
The beneficial effects of the utility model：The utility model has that circuit structure is simple, wiring is simple, easily makes, makes
The advantages that with facilitating, finished-product volume is small, good insulation preformance, cost-effective；The utility model not only substantially reduces the testing time,
And test leakage phenomenon is effectively prevent, the accuracy and reliability of Substation secondary circuit Insulation test are greatly improved, very well
Solve the problems, such as exist during secondary cable Insulation test, reduce secondary circuit insulation it is unqualified caused by power network fortune
Sector-style danger；Wiring is simple, simple operation, optimizes Insulation test process, effectively shortens newly-built, technology innovation project construction, checks and accepts
The Insulation test activity duration；On-site personnel is freed from a large amount of mechanicalnesses, repetitive operation, avoids tired work
Industry, improve operating efficiency.
Brief description of the drawings
