Abstract
The utility model relates to an embedded current transformer test device, which belongs to the technical field of an experiment of a current transformer of a transformer. According to the technical scheme, the embedded current transformer test device comprises a turn ratio instrument (1) and a tested current transformer (2), wherein a high-voltage side of the turn ratio instrument is connected to a coil head of the tested transformer; a low-voltage side of the turn ratio instrument is connected to a phase on which the tested transformer is; and a low-voltage side of the tested current transformer is in short circuit through a lead. The embedded current transformer test device has the beneficial effects of being simple to operate, high in practicability and high in generalization performance; an extra device does not need to be added to the device; the measurement method of an existing current transformer is enriched; and particularly, a good test method is provided for a transformer arranged on the spot. Therefore, the embedded current transformer test device improves efficiency, and is simple and rapid.
Description
Technical field
The utility model relates to a kind of embedded current transformer testing device, belongs to the current transformer experimental technique field of transformer.
Background technology
At present, in the test of transformer dairy products, when measuring the current transformer ratio that cooperates use with transformer, normally need to carry out the no-load voltage ratio test at the special current transformer tester of the unassembled front usefulness of current transformer, but, sometimes also special circumstances can appear, so that just be assembled on the transformer in the situation of not test at current transformer.The method that measure this moment has two kinds, and the one, measurement when waiting complete opening of this transformer test, but concerning some was embedded current transformer, solution just seemed improper like this; The 2nd, when test product is done load test, survey no-load voltage ratio from the current transformer access reometer of test product, this method labor capacity is large, needs many people to cooperate, and the instrument of access is also many, and inefficiency is inadvisable.
The utility model content
The purpose of this utility model provides a kind of embedded current transformer testing device, be applicable to embedded current transformer and be installed to straight-through current transformer on the transformer, need not add new equipment, use the equipment of existing test transformer voltage ratio can finish test, simple and fast solves the problems referred to above that background technology exists.
The technical solution of the utility model is: embedded current transformer testing device, comprise turn ratio instrument and tested current transformer, the high-pressure side of turn ratio instrument connects tested mutual inductor coil and lifts one's head, the low-pressure side of turn ratio instrument connects tested mutual inductor place phase, the low-pressure side of tested current transformer is by the wire short circuit, input tested current transformer ratio, so just can in transformer finished products, measure current transformer ratio.Applicable too for mounted straight-through current transformer.
Good effect of the present utility model: simple to operate, practical, do not need to add extras, have very strong generalization, enriched the measuring method of existing current transformer, especially provide a good method of testing to field erected transformer, raise the efficiency simple and fast.
Description of drawings
Fig. 1 is the structural drawing of the utility model embodiment;
Among the figure: turn ratio instrument 1, tested current transformer 2.
Embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is described further.
Embedded current transformer testing device, comprise turn ratio instrument 1 and tested current transformer 2, the high-pressure side of turn ratio instrument connects tested mutual inductor coil and lifts one's head, the low-pressure side of turn ratio instrument connects tested mutual inductor place phase, the low-pressure side of tested current transformer is by the wire short circuit, input tested current transformer ratio, so just can in transformer finished products, measure current transformer ratio.
With reference to accompanying drawing 1, the low pressure end of tested current transformer 2 is by the wire short circuit, CT is the tested current transformer of high pressure A phase, the high pressure A of turn ratio instrument meets the 1S1 of tested current transformer, high pressure B meets the 1S2 of tested current transformer, the low pressure a of turn ratio instrument connects tested current transformer high pressure A phase, and the low pressure b of turn ratio instrument connects tested current transformer high pressure O phase.Behind the turn ratio instrument input correlation parameter, can measure no-load voltage ratio and the polarity of tested current transformer.
