Specific embodiment
Describe this utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining this utility model, but it is not intended as to restriction of the present utility model.
As shown in Figure 1-2, this specific embodiment is employed the following technical solutions：No-load voltage ratio tester, it includes housing；It is described
Housing be provided with the p-wire of multiple sockets for being connected with enclosure interior circuit control panel and described multiple sockets electrical connection；
Described multiple sockets include high voltage interface 2, low-voltage interface 3, power interface 5, ground interface 7；Described enclosure interior is provided with
Battery 9 and multiple modules 8；Described multiple modules 8 are connected by electrical connection with multiple sockets on housing.
Further, described high voltage interface 2 includes A, B, C；Described low-voltage interface 3 includes a, b, c.High-pressure side：It is high
Pressure side A, B, C are connected respectively by yellow, green, red p-wire with high pressure A, B, C terminals of transformator.Low-pressure end：Low-pressure end a,
B, c are connected respectively by low pressure a, b of yellow, green, red p-wire and transformator, c terminals.
Further, described housing is provided with display 1, keyboard 6, printer 4.
Originally it is embodied as operation principle：Test clamp is correctly coupled according to the concrete condition of tested transformator.Instrument connects
After the completion of line, plug in line, turns on the power switch, and carries out parameter modification, time setting, single-phase transformer or PT mutual inductor measurings
Amount, after measurement is finished, currently displaying data can be printed if desired for printing by printing key.
As shown in figure 3, specific embodiment embodiment one, Y-d-11, the change of 110 ± 8 × 1.25%/10.5KV of combinations of voltages
Depressor.
Turn on the power switch, can now be input into nominal transformation ratio value, according to the high tension voltage value 110.0 on transformator nameplate,
Low voltage voltage 10.5, calculates nominal transformation ratio 10.476, is input into nominal transformation ratio 10.476, and tap sum 17 taps spacing
1.25%, after the completion of input, main menu is returned to by return key, F1 keys are pressed, instrument starts measurement.
As shown in figure 4, specific embodiment embodiment two, the single-phase transformation of the √ 3 ± 8 × 1.25%/20 of combinations of voltages 525/
Device.
Turn on the power switch, operation is similar to upper example, and the simply calculating of nominal transformation ratio should be noted that transformator nameplate high-tension electricity
Pressure value (525/1.732=) 303.1, low-pressure side voltage 20, value of calculation is 303.1/20=15.155, is input to nominal transformation ratio position
Put, in parameter setting, high pressure mode is made into " list ", nominal transformation ratio makes 15.155 into, and total number of taps makes 17 into, taps spacing
Make 1.25%, after the completion of modification into, press F1 keys and tested.
After said structure, what this specific embodiment was produced has the beneficial effect that：It has, and test speed is fast, accuracy
Height, small volume, lightweight, employing once complete the test of three-phase no-load voltage ratio, greatly save the on-the-spot test time, are the test of client
Bring very high efficiency.
The above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should cover in the middle of right of the present utility model.
