Description
Technical field
The utility model relates to the transformer parameter technical field of measurement and test, relates in particular to a kind of transformer multiparameter batch testing system.
Background technology
Transformer is the Primary Component of household electrical appliance, electrical equipment, is directly connected to equipment and whether can satisfies state compulsion 3C authentication requesting, more relates to user's property and life security, thereby the transformer parameter test becomes very necessary.At present, in the production run of transformer, the scheme of transformer parameter test is one one in a transformer, tests for one one, or further several continuous parameters of a transformer is tested.Because the test of transformer not only comprises the precision measurement of electrical quantity but also use 4000 volts, 6000 volts even above high-tension safety test up to ten thousand volts, so need to adopt multiple different equipment, as electric current, voltage, power factor and power consumption etc. adopt a kind of equipment, but need adopt high voltage testing device when carrying out voltage-withstand test, be used for the switch commonly used of conversion testing item (as conventional relay in the general automatization test system, the light lotus root, mechanical switch) can't bear so high voltage, thereby other connecting lines of transformer will disconnect during voltage-withstand test, causing when other parameters of test and voltage-withstand test needs ceaselessly wiring and removes line, step is very loaded down with trivial details, institute can't guarantee that in steps all by manually finishing omission and test that human factor produces do not conform to rule, also do not have complete test record simultaneously.
Thereby a kind of all parameters that can not only disposable accurately measuring transformer, and need not rewiring thoroughly solve the design that possesses the smart machine of the collaborative test of many electric parameters of transformer in batches of high-voltage breakdown problem and produce and just seem very necessary.
Summary of the invention
Measure the defective that existence is dispersed, the artificial wiring of need causes poor efficiency, measuring error is big at the transformer parameter of prior art, the utility model provides a kind of all parameters that can not only disposablely accurately measure a transformer, and need not rewiring, can thoroughly solve the transformer multiparameter batch testing system of high-voltage breakdown problem.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of transformer multiparameter batch testing system, the tested transformer that comprises several same models, the transformer excitation power supply, high pressure generator, described transformer excitation power supply is connected the primary input terminal of tested transformer, high pressure generator is connected between the winding of tested transformer, also comprise several hyperchannel electric parameter test cells, the primary input terminal of the tested transformer of several same models inserts the data import of same hyperchannel electric parameter test cell, the same secondary output end of the tested transformer of several same models inserts the data import of same hyperchannel electric parameter test cell, between each hyperchannel electric parameter test cell and the civil power, all be connected a high insulated isolation transformer between transformer excitation power supply and the civil power, be connected leakage current between high pressure generator and the tested transformer and detect mutual inductor.This structural design is with equipotential group of elementary or same secondary composition of tested transformer, tested like this transformer has several groups of insulation windings just to form several equipotential group, Hi-pot test can be carried out between each equipotential group, each equipotential group can only be equipped with a High-Voltage Insulation transformer that is used to isolate, it is high greatly to have reduced price, the quantity of bulky High-Voltage Insulation transformer, in each equipotential group, the interchannel insulation request of A/D of hyperchannel electric parameter test cell reduces greatly, thereby can realize the analog acquisition of duplex high precision easily.
As preferably, described hyperchannel electric parameter test cell comprises test processes CPU, the A/D converting unit is connected between the input end of data import and test processes CPU, and the wireless communication module that is connected with test processes CPU is connected to PC by the micro power consumption wireless communication unit.The employing of wireless communication module has reduced wiring, has avoided suffering by wiring the risk of high-voltage breakdown.
As preferably, also comprise the transformer group testing jig, the tested transformer of several same models is inserted on the transformer group testing jig.Avoided the wiring confusion, also made the number transformer of access have extendability preferably simultaneously.
A kind of transformer multiparameter batch testing described in the utility model system can not only carry out hyperchannel in batches, the high precision electric parameter measurement, and the measurement that can carry out the high-voltage breakdown electric current under the situation that does not change wiring judges, has that cost is low, efficient is high, measurement is comprehensive, advantage of high precision.
