Below in conjunction with accompanying drawing the utility model is done to describe in further detail, seen also Fig. 1 to Fig. 3.
As shown in Figure 1, a kind of aircraft AC circuit breaker test unit, comprise DBG exerciser 1, for tested product provides the AC load device 2 of variable load electric current, the supply unit 3 to 1 power supply of tested product and DBG exerciser, the interface arrangement 4 that is electrically connected with tested product, it is interconnected that described DBG exerciser 1, AC load device 2 and interface arrangement 4 pass through three-phase circuit.
As shown in Figures 1 and 2, a kind of aircraft AC circuit breaker test unit is characterized in that described DBG exerciser 1 comprises power unit 101, display part 102, control section 103, AC load apparatus connection interface 104, tested product connecting interface 105.Described power unit 101 is made up of gauge tap SA1, D.C. contactor KM1, fuse etc., display part 102 is made up of voltage table, reometer and electric capacity and pilot lamp, control section 103 comprises switch SA2, SA3, and D.C. contactor KM2, KM3 form.
As Fig. 1 and shown in Figure 3, described 2 AC load devices are by resistive load control module 201, resistive load module 202, inductive load control module 203, inductive load module 204, and current adjusting module 205, display control module 206, product interface module form 207.
The utility model major function is to realize that the key technical index of stipulating in the finished product technical conditions is the measurement of contact voltage drop and ampere-time characteristic index.The test that realizes these two indexs need provide condition of work to tested finished product: three-phase 115V voltage, power factor are 100% and 200% nominal load current of Cos=0.6～0.7, simultaneously, proving installation should be able to be realized the connection of finished product and the control conversion of duty.The concrete following several respects of branch of implementing are carried out:
Supply unit 3 provides and exchanges 115V, 400Hz power supply and direct current 28V power supply.Supply unit 3 effects are to provide test unit and the required operating voltage of tested product work on the one hand, on the other hand external power source and test unit are kept apart, and can in time protect equipment and personal security when line fault.
The required load current of tested product is supplied with by AC load device 2 of the present utility model.This AC load device is under three-phase alternating current 115V rated voltage, and 202 resistive load modules can provide 0A～100A resistive load, 204 inductive load modules every phase under the control of 203 inductive load control modules that 0A～30A inductive load can be provided at least in every phase under the control of 201 resistive load control modules at least.Load current by 205 current adjusting module carry out 8A, 4A, 2A, the 1A mode makes up, and can guarantee the adjustment of every phase power factor Cos Φ=0.6～0.95, can be adjusted into different integer current values arbitrarily.And vernier adjustment knob is arranged, be used for adjusting the current value that keeps a position effective digital behind the radix point and make up with round values.Use resistive loads separately or use the inductive load under the different capacity factor Cos Φ, the electric current that carries out and have perfect overtemperature, overload protection and 2 outputs of AC load device, voltage, power factor, frequency demonstration by showing that controller module 206 is controlled; the product interface module is connected with DBG exerciser 1 AC load device 2 with tested finished product, be the required load current requirement that AC load device 2 satisfies the finished product index measurement fully.
DBG exerciser 1 is core of the present utility model, and contactor is used for finished product and carries out the control conversion that contact voltage drop is measured and ampere-time characteristic is measured.When measuring, contact voltage drop uses 100% rated current, and carry out using when ampere-time characteristic is measured 200% rated current, test unit must be supplied with and adjustment and transformed load reliably, fast, and DBG exerciser 1 has used two HJJ-100 D.C. contactors of KM2, KM3 for this reason.The KM2 contactor is that contactor is adjusted in load, and its contacting back loading device is thrown off product and inserted test unit, and testing crew carries out the adjustment of the required power-factor of load and electric current, has guaranteed that finished product works under stable load current.The KM3 contactor is finished product work contactor, and finished product obtains required operating voltage and load current is started working behind its contacting, and the experimenter carries out contact voltage drop and ampere-time characteristic index test.
Interface arrangement 4 is used for tested finished product is inserted pilot system.The required working current of DBG exerciser 1 and AC load device 2 output control signals and product work is given tested finished product by interface arrangement 4.
Tested product is inserted test circuit by figure, and this moment, the finished product working handle necessarily was in off-state.After the power supply that supply unit 3 provides is supplied with 101 power units of 1DBG exerciser, connect SA1, the SA2 power switch of 101 power units, the H4 DC control pilot lamp of 102 display parts ignites, and PV4 voltage table indication circuit has direct current 28V control voltage.Direct-current control voltage is mainly used in making the action of 101 power unit KM1 D.C. contactors, and the contact adhesive is served alternating current to AC load device 2 and tested product.Here use the working method of the big electric current of little Current Control, used the contact of D.C. contactor to connect the AC great current circuit, guaranteed the reliability of power supply.Three-phase voltage enters the 1DBG exerciser, and the indication of power supply signal has adopted electric capacity to add the mode of small-sized DC pilot lamp, can make equipment small and exquisite succinct.Alternating current ammeter will adapt to the request for utilization of big electric current, selects the 0-50A reometer, therefore needs to use mutual inductor at reometer.Need before the manufacture test to adjust suitable load current value by the different model AC circuit breaker earlier.The SA3 of 103 control sections is pulled to " short circuit " position, the action of KM3 D.C. contactor, contact load device line attachment, by 206 display control modules on the combination adjustment AC load device, resistance with 206 display control modules, inductance switch is selected suitable finished product load current value and power factor value, after adjusting the SA3 switch of 103 control sections is pulled to " work " position, the KM3 DC relay of 103 control sections loses voltage, the contact disconnects, the KM2 D.C. contactor of 103 control sections gets, the contact adhesive, connect the finished product working handle, the load of before adjusting inserts finished product, and can carry out contact voltage drop and ampere-time characteristic test this moment to tested product.The automatic tripping circuit of tested product or disconnection finished product handle back loading device also break away from circuit, finish performance test.
The utility model is successfully realized the accurate test of used three-phase alternating current and single-phase AC isolating switch key characteristic in the electric route of present stage aircraft, guarantees the quality of crucial finished product in the electric route of aircraft complex.The design of the utility model principle and parameter are selected with strong points, stable and reliable for performance, easy and simple to handle, the measuring accuracy height, and the test condition high conformity, test speed is fast.From cost, cheap, be better than domestic similar testing table.Test fixture does not have excessive demand to the physical dimension of tested finished product, goes for the test of different model AC circuit breaker.Be applicable to that the proving installation of three-phase 115V feed circuit is equally applicable to the work of each model 115V single-phase circuit breaker, makes proving installation have good extendability.The extensive practicality of test load can be achieved the test of civilian 220V isolating switch by the small change of this equipment.The design of this test unit meets man-machine work efficiency principle, simple to operate, easy to maintenance, safe and reliable, has improved work efficiency in actual use greatly, has saved the working time.
