Description
Technical field
The invention belongs to field of aviation measurement and test, particularly relate to a kind of big current surge proving installation.
Background technology
At present, to the important evidence of aircraft carrier aircraft device power supply (DPS) security examination is proof voltage surge (anti-overvoltage, under-voltage surge) test among the GJB181-86/GJB181A-2003 " aviation power supply characteristic and to the requirement of consumer ", and aircraft carrier aircraft equipment great majority need carry out this project testing.At the testing apparatus fast transient burst generator UCS500 of existing configuration, only support the direct supply test, and be 16A by its maximum current.And along with the continuous upgrading of airborne equipment, power supply is powered, and type is various (to comprise DC28V/270V, AC115V400Hz etc.), its electric current that needs increases gradually, some special equipments particularly, its electric current has reached more than the 200A, present testing apparatus both domestic and external does not also reach big electric current index, and only with existing little testing current equipment, can't carry out the proof voltage surge test of big electric current carrier aircraft equipment, cause equipment component not carry out just directly installation of this project test, thereby cause that aircraft can not resist overvoltage because of part carrier aircraft equipment, under-voltage surge impact and influence the significant problem of aircraft safety.Need to design a kind of big electric current overvoltage, under-voltage surge test device for this reason, solve big electric current overvoltage, the under-voltage surge test difficult problem of different electrical power kind.

Embodiment
Below in conjunction with accompanying drawing the present invention is done to describe in further detail, see also Fig. 1 to Fig. 3.
As shown in Figure 1, be the little current surge of tradition (overvoltage/undervoltage, withstand voltage excessively, direct current and interchange) the proving installation synoptic diagram, this device is by electrical fast transient burst generator 3 first power supply 1 and second source 2 to be changed according to the high voltage and the low-voltage of standard-required, and the control transformation time, carry out by overvoltage of trial product AC and DC and under-voltage surge test.At present, it is 16 amperes that the testing apparatus electrical fast transient burst generator 3 on the domestic and international market only can bear maximum current, and present all not the high-current test means and the device of this project of domestic each test experience chamber.And along with development of science and technology, the electric current that tested device requires has reached more than 200 ampere, and this test macro can not be satisfied the demand.
As shown in Figures 2 and 3, a kind of big current surge proving installation, comprise first power supply 1, second source 2, electrical fast transient burst generator 3, also comprise a contactor 4, described electrical fast transient burst generator 3 is connected with control computer 5, and is connected with contactor 4, and the switch 6 of contactor 4 inside is connected with equipment under test 7, by the switch 6 of electrical fast transient burst generator 3 control contactors 4 inside, realize the conversion between first power supply 1 and the second source 2.
On the coil 8 of contactor 4, be parallel with a diode, be parallel with a diode on switch normally closed contact 9 and the normally opened contact 10 respectively.
On contactor 4, also be provided with a terminal block 11, be used to connect contactor 4, first power supply 1, second source 2 and diode.
The coil 8 of the present invention by electrical fast transient burst generator 3 control contactors 4, the further break-make of control contactor 4 internal switches reaches that AC and DC is crossed, the index of under-voltage surge test requirement.Because the switching characteristic of contactor 4 influence; understand and produce the useless voltage of spike clutter excessively; in order to eliminate this useless peak voltage of crossing; and protection is by trial product 7; two ends at the coil 8 of contactor 4 are connected with the diode that shields; eliminate useless peak voltage simultaneously, finally make to be added to by the complete conformance with standard of the surging signal on the trial product.
