[embodiment]
In order to achieve the above object, the High-Voltage Insulation proving installation of the cable that the utility model provides, described cable 10 1 ends have wire and cable connector 20, and described wire and cable connector 20 has odd bits terminal 21 and even bit terminal 22, and this proving installation comprises:
Device connector 30, it has the odd bits interface 31 corresponding with described odd bits terminal 21, the even bit interface 32 corresponding with described even bit terminal 22;
Several first wires 40, one end are corresponding one by one respectively to be connected with described odd bits interface 31, and the other end comes together in the first contact 50;
Several second wires 60, one end are corresponding one by one respectively to be connected with described even bit interface 32, and the other end comes together in the second contact 70;
Direct supply 80, its selectivity are connected in 70 of described the first contact 50 and described the second contacts;
Display unit, it is electrically connected at 70 of described the first contact 50 and described the second contacts;
High voltage testing device 100, its selectivity are connected in 70 of described the first contact 50 and described the second contacts, and described high voltage testing device 100 has testing current unit 101, resistance test unit 102, respectively leakage current and the resistance value of cable 10 under the testing high voltage.
Wherein, described display unit can also be serially connected with switch 110, in order to protect described display unit.
Wherein, described display unit can be light emitting diode 90.
Wherein, described direct supply 80 voltages can be for 3～～5V.
Wherein, described high voltage testing device 100 employed high pressure can be selected from direct current or the AC power of 150V, 250V, 500V.
When test, described direct supply 80 is connected in 70 of described the first contact 50 and described the second contacts, closed described switch 110, if described light emitting diode 90 is luminous, the odd bits interface 31 that device connector 30 then is described and even bit interface 32 are without short circuit, again described wire and cable connector 20 is inserted described device connector 30, if described light emitting diode 90 is still luminous, the odd bits terminal 21 that described wire and cable connector 20 then is described and even bit terminal 22 are without short circuit; Again described direct supply 80 is withdrawn, be changed to high voltage testing device 100 is connected in 70 of described the first contact 50 and described the second contacts, if the result that described testing current unit 101, resistance test unit 102 are tested all meets standard, then the High-Voltage Insulation test is passed through.
The standard of High-Voltage Insulation test is to need its leakage current less than one first preset value (for example being 1mA), and its resistance is greater than one second preset value (for example being 20M Ω).Because adopting this mode to test with even bit terminal 22 with previous adjacent two odd bits terminals 21 compares, it has been equivalent to more resistance in parallel, and both end voltage is constant, leakage current when therefore its leakage current is greater than single the survey, if the leakage current that measure this moment still less than the first preset value, must pass through when then list is surveyed.As a same reason, for the test of resistance, because more resistance in parallel, the inevitable resistance during less than single survey of its resistance is if the resistance of this moment still greater than the second preset value, then must pass through during single the survey.
When adopting proving installation of the present utility model that cable 10 is carried out actual test, leakage current is 0.034mA, and test is passed through, and leakage current was 0.021mA when the list of its correspondence was surveyed, and naturally can pass through especially; The resistance of resistance is 13.5G Ω, and the resistance of resistance was 26G Ω when the list of its correspondence was surveyed, and naturally can pass through especially.
As seen, utilize the High-Voltage Insulation proving installation of cable of the present utility model, because odd bits terminal 21 and even bit terminal 22 with described wire and cable connector 20, finally come together in described the first contact 50 and described the second contact 70 by described device connector 30, therefore test convenient, and testing time still less, reaches the timesaving effect.
