1) power state detection
Programmable power supply module output voltage or frequency are realized over-voltage by the index of test request, under-voltage, overfrequency, are owed
Frequency exports after being configured, and is adopted after being isolated by supply input of the conditioning module to airborne power supply by AD board
Collection, judges whether the output state of power supply meets test index according to collected signal, program starts timing after satisfaction, simultaneously
The 115V voltage output end for acquiring airborne power supply, judges whether power down, after meeting test request, timing terminates.Programming
In consider product failure situation, the judgement of response time and output voltage to product carries out range setting, time-out or superpressure
Program is automatically powered-down after under-voltage exits and shows fault cues.
2) over-voltage and over-current is tested
After electric control module work, switching airborne power supply is that band carries mode, is switched to setting by controlling load blocks
Nominal value, by control load parameter realized current test, electric current index is acquired by output of products end gauge outfit.
3) test resource explanation
Component is more demanding to artificial mains, is equipped with the power reguirements that programmable power supply is used to meet equipment.
Equipment is equipped with program-control electronic load, and load when to overcurrent controls, and selects the electronic load of a 2KW, leads to
RS232 control is crossed, the single-phase load capacity of AC20A is reached.
4) electric control module
Test equipment requires the output to programmable power supply to carry out software control, therefore passes through contactor composition control module,
220V power supply, the output of 0-12V three-phase, 0-115V three-phase, 0-115V single-phase output are controlled and switched.Contactor is not according to
Same current requirements select direct current or A.C. contactor respectively, and control coil uniformly selects 24VDC specification, main contacts selection
3NO1NC form is used for control interlocking.
The control of contactor is divided into two parts: manually controlling the switch button realization by panel, automatically controls and pass through two
Block relay module realizes that relay module is finished product, passes through 485 Communication Controls.
The electric control system of test equipment is the key that entire test macro, fully takes into account test signal in design
Index properties and test request, system use two-step evolution, panel manual switch be level-one control, software be Two-stage control portion
Point, substantially ensure the safety of system operatio.Based on considerations above, electric part selection is real by the end main contacts NC of contactor
It now interlocks, forms entire electric control module.Mainly include following part:
1. contactor controls the interlocking realization of signal, phase sequence selects interlocking realization；
As shown in figure 5, the interlocking in this equipment is mainly realized by two ways, one is the interlockings of control signal, mainly
It is that the end NC of band on used contactor main contacts is realized, if the control signal of A contactor is by behind the contact NC of B contactor, then
Be connected on A contactor, it is ensured that when A contactor inhale and when, B contactor once motion, A contactor turns off, this interlocking
Mode is used primarily in two and needs between interlocking contactors, as 115V three-phase and single-phase selection, the switching of 115V negative phase sequence,
In the switching of 115V output loading；Another kind is the interlocking between three contactors, 115V selection A B C phase sequence when, A is communicated
The port NO for crossing A contactor, is then connected to the end NC of C contactor, and three contactors successively interlock, it is ensured that only one primary phase
Sequence can be input to unit under test.
2. equipment 220V power supply control
As shown in fig. 6, equipment is powered by 220 input of outside, after filter process, pass through two panel-switch SW1
Total power switch, SW2 scram button, control K18 contactor, and K18 selects 220V control, complete the system power supply of equipment
Control.
3. as shown in fig. 7, the load control of components A C115V three-phase alternating current；Power supply output after, first pass through K15, K16 two it is soft
After the interlocking contact device of part control completes output selection, in the K17 contactor controlled by panel-switch SW8, complete cheek
The band of output carries control.
5) acquisition module explanation
The signal acquisition of test equipment is divided into three parts: the acquisition of panel gauge outfit, programmable power supply SENSE end readback, collection plate
Card is read.
Gauge outfit is exchanged, alternating-current meter is combined using famous-object three, the acquisition precision of voltage, electric current and frequency reaches 0.5%.
Direct current gauge outfit, select famous-object direct current table, voltage, electric current acquisition precision reach 0.5%.
Alternating-current meter and direct current table are equipped with 485 communication modules, and 485 boards being equipped with by computer, software can will join
Number collects test macro in real time.
Voltage, electric current, frequency can be passed through the port RS232 by programmable power supply readback, the then end SENSE carried by power supply
It is acquired in real time.
6) analog input card, be mainly responsible for read the AC12V that power to component AC115V three-phase and component output
Voltage, the current value of 115V three-phase.Board carries out data output by serial ports.
Tested power supply is connected by cable with test equipment, and operator opens corresponding test software, selects product type
And after inputting piece number, program enters test mode by 232 control power supplys and load, and into test program, program is automatically brought into operation
The electric control module in box is controlled, after powering on for product, the gauge outfit installed by control panel 2, real-time detection input and defeated
Voltage out, electric current, a-c cycle value and in interface real-time display, by analog input card (module), acquisition input in real time
AC0-200V voltage, frequency, AC voltage, the electric current of output record test result according to the regulation of testing process.When
After the completion of test, in interface display as a result, judging whether the value is qualified simultaneously, report is filled in, is saved.
This test equipment has the function of power supply status control, load control, response time test, phase sequence test etc., has
The features such as integrated level is high, compatibility is high, rich interface；Using general test cabinet structure, carry industrial personal computer, test instrumentation,
The components such as control switch carry out function and performance test to intermediate frequency (115V/400HZ) AC power source, pass through replacement and operating surface
The different cables of plate connection, realize the test of multiple power sources, applied widely.
The content not being described in detail in the utility model is the prior art, and the software control in embodiment is not belonging to
The range of the utility model protection, and it is the prior art, therefore is not belonging to the improvement proposed to method itself.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
