[embodiment]
In order to achieve the above object, the High-Voltage Insulation proving installation of cable provided by the invention, described cable 10 one end 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, its one end is corresponding one by one to be respectively connected with described odd bits interface 31, and the other end comes together in the first contact 50;
Several second wires 60, its one end is corresponding one by one to be respectively connected with described even bit interface 32, and the other end comes together in the second contact 70;
Direct supply 80, its selectivity is 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 is 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 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 3～～5V.
Wherein, the high pressure that described high voltage testing device 100 is used can be selected from direct current or the AC power of 150V, 250V, 500V.
When test, described direct supply 80 is connected in to 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 is described with even bit interface 32 without short circuit, again described wire and cable connector 20 is inserted to 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 is described with even bit terminal 22 without short circuit; Again described direct supply 80 is withdrawn, be changed to high voltage testing device 100 is connected in to 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, High-Voltage Insulation test is passed through.
The standard of High-Voltage Insulation test is to need its leakage current to be less than one first preset value (being for example 1mA), and its resistance is greater than one second preset value (being for example 20M Ω).Because adopting which tests and compares with even bit terminal 22 with previous adjacent two odd bits terminals 21, 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 survey, if the leakage current of now measuring is still less than the first preset value, when list is surveyed, must pass through.As a same reason, for the test of resistance, due to parallel connection more resistance, resistance when its resistance must be less than single survey, if resistance now is still greater than the second preset value, must pass through during single survey.
When adopting proving installation of the present invention to carry out actual test to cable 10, leakage current is 0.034mA, and test is passed through, and when the list of its correspondence is surveyed, leakage current is 0.021mA, naturally can pass through especially; The resistance of resistance is 13.5G Ω, and when the list of its correspondence is surveyed, the resistance of resistance is 26G Ω, naturally can pass through especially.
