The general-purpose tester disclosed by the utility model integrates effective functions so as to improve the working efficiency, reduce the labor intensity, have an automatic measurement process and effectively reduce time for testing.
Description
Technical field
The utility model belongs to the instrument that the method for electricity consumption is measured, and especially belongs to integrated testing instrument for transformer.
Background technology
Traditional instrument will be realized main transformer direct current resistance, the no-load voltage ratio of measuring transformer, the parameter of these three projects of load ratio bridging switch, with three different instruments, measures respectively item by item, measure the wiring amount large, complicated, setting up time is long, and labour intensity is large, inefficiency.Straight resistance is measured repeatedly the manual change and is measured wiring, and high pressure, middle pressure, low-pressure side are measured minute three wiring and just can be finished a pilot project, and power off time is long, and the staff steps on visit often, has greatly wasted the man power and material.
Summary of the invention
The utility model purpose is to overcome above-mentioned shortcoming, provide the parameter of a kind of main transformer direct current resistance that can detect simultaneously transformer, no-load voltage ratio, load ratio bridging switch three-phase dc resistance, no-load voltage ratio, the integrated testing instrument for transformer of carrying is arranged.
The technical scheme that the utility model adopts is a kind of integrated testing instrument for transformer, its main points are, it comprises PC, Control and signal of communication switch unit, the three-phase dc resistance meter, no-load voltage ratio tester, the comprehensive tester of carrying is arranged, relay board, the p-wire output terminal, with the three-phase dc resistance meter, no-load voltage ratio tester, there be disposable all the connecting by the relay board unification of wiring of carrying on the comprehensive tester to be connected to the p-wire output terminal, by relay board with the three-phase dc resistance meter, no-load voltage ratio tester, have the different instruments that carry comprehensive tester to export needed p-wire and switch, utilize PC by Control and signal of communication switch unit with the three-phase dc resistance meter, no-load voltage ratio tester, there is the test data of carrying comprehensive tester to be transferred to PC.
PC control communication protocol plate switches the needed output connection of different instruments, and when needing the magnetic assist method as measuring direct current resistance, instrument can be annotated magnetic from the trend high-pressure side, finish the measurement to low-pressure side; Measurement has the time of carrying, and Control is but changed to a low pressure short circuit ground connection, prevents the induction electromotive force jamming equipment; When no-load voltage ratio is measured, according to the parameter that host computer arranges, relay can automatically switch to high pressure centering press measure or high pressure to the measurement of low pressure.All wiring only need to get main transformer and high, normal, basicly all connect by p-wire is disposable, just can finish no-load voltage ratio by handling upper computer software, have year, the surveying work of direct current resistance.
Three-phase dc resistance meter, no-load voltage ratio tester, on-load tap changer tester, these three kinds of instruments have following common feature: A, measure main transformer; B, p-wire all are four groups (Aa, Bb, Cc, Oo); C, power supply capacity are roughly the same, take the measuring resistance principle as main project; D, test connecting line length are consistent, and mode of connection is roughly the same.Therefore based on above reason, the tap position of finishing transformer directly hinders, the quick test of tap position no-load voltage ratio, load ratio bridging switch and short-circuit impedance, with these being combined into one of test apparatus to a test cell, realization primary connection, single job.
The utility model has the advantage of that measuring process is automatic, effectively reduce the test time spent.By effective Function Integration Mechanism, reduce volume, reduce connection times, increase work efficiency, reduce labour intensity, time shorten 2/3 is the test method of maintenance department an urgent demand.Primary connection finishes no-load voltage ratio, have carry, three kinds of tests of direct current resistance.
