Abstract
The utility model relates to a standard coil for testing idle load data of a C-shaped iron core of a voltage transformer. The standard coil comprises a booster, an ampere meter, a standard coil, a voltmeter and a coiling paper tube, wherein the booster, the ampere meter and the standard coil are serially connected in turn; two ends of the voltmeter are in parallel connection with the standard coil; and the standard coil is wound on the outer wall of the coiling paper tube. A lead is wound on the paper tube of a fixed size for a standard number of circles, thereby forming the standard coil. The C-shaped iron core is more simply and conveniently screened during an initial testing process.
Description
Technical field
The utility model belongs to the mutual inductor electronic device field, particularly relates to the unloaded data test of a kind of C-type ironic core of voltage mutual inductor and uses standard coil.
Background technology
Iron core is one of important component part of voltage transformer (VT); The quality of quality unshakable in one's determination will directly have influence on the measuring accuracy and the serviceable life thereof of voltage transformer (VT); So in the middle of the R&D and production process of voltage transformer (VT); It is to be even more important that the detection of quality unshakable in one's determination is just become, and volt-ampere characteristic is one of important parameter of examination quality unshakable in one's determination, in traditional voltammetric characteristic measuring process unshakable in one's determination; Often have following defective: test process can not really embody product actual motion environment, and the traditional test flow process can cause production cost of products too high.
Summary of the invention
The utility model improves the pick-up unit unshakable in one's determination that has voltage transformer (VT) now for the technical matters that solves above-mentioned existence, proposes the unloaded data test of C-type ironic core of voltage mutual inductor a kind of simple in structure, easy to use and uses standard coil.
The utility model is for solving the technical matters that exists in the known technology, and the technical scheme of being taked is: the unloaded data test of a kind of C-type ironic core of voltage mutual inductor is used standard coil, comprises stepup transformer, reometer, standard coil, voltage table and coiling paper tube; Said stepup transformer, reometer and standard coil are connected successively, and said voltage table two ends are parallelly connected with standard coil, and said standard coil is wound in coiling paper tube outer wall.
As optimal technical scheme, the utility model can also adopt following technical measures:
Said standard coil is wound in coiling paper tube outer wall, its direction of winding be the right side around to.
Said standard coil is provided with at least two taps.
Advantage and the good effect that the utlity model has are: one, be wrapped on the fixed sturcture through standard coil, make in test process, only need to change iron core to be measured, do not need to twine again, thereby saved the time of test greatly; Two, a plurality of taps are set on the standard coil, make in test process, can change the tap interface as required, increased the dirigibility of test process greatly.Three, this utility model can be avoided the waste of material largely in existing testing process unshakable in one's determination.Four, this measurement can be monitored the consistance of no-load curve unshakable in one's determination in the initial period of producing, and directly had influence on the final zero load coupling of product.

Wherein: 1, stepup transformer; 2, reometer; 3, standard coil; 4, voltage table; 5, tap; 6, coiling paper tube; 7, iron core.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, the technical scheme that the utility model adopts is: the unloaded data test of a kind of C-type ironic core of voltage mutual inductor is used standard coil, comprises stepup transformer 1, reometer 2, standard coil 3, voltage table 4, iron core 7 and coiling paper tube 6; Said stepup transformer 1, reometer 2 and standard coil 3 are connected successively, and said voltage table 4 two ends are parallelly connected with standard coil 3, and said standard coil 3 right sides are around in coiling paper tube 6 outer walls; Said standard coil 3 is provided with three taps 5.Said unshakable in one's determination 7 axis from coiling paper tube 6 pass.
The concrete course of work of the utility model is: be around in standard coil 3 magnitude of voltage (2%, 5%, 80%, 100%, 120%, 190% rated voltage) that requires of GB in addition on coiling paper tube 6 outer walls to the right through stepup transformer 1; Read current value and the magnitude of voltage at standard coil 3 two ends in the standard coil 3 through reometer 2 and voltage table 4; Can draw unshakable in one's determination 5 VA characteristic curve according to the magnitude of voltage of measuring gained and current value; Through connecting different tap 5, can realize voltammetric characteristic measuring to different no-load voltage ratio products.Need to change 7 o'clock unshakable in one's determination, only need from coiling paper tube 6, extract out original unshakable in one's determination 7, the iron core 7 after will changing then inserts and gets final product, and operates more convenient.
More than a kind of embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
