Abstract
The utility model discloses an automatic detecting wire cross-core guiding assembly for a low voltage current transformer, which comprises a frame and a guiding mechanism. The guiding mechanism is composed of an insulation roller and two recessed wheel bearing servo-actuators. The surface of the insulation roller is provided with a ring of grooves that are mated with the diameter of the one-time wiring cross-core rod of an automatic detecting wire. The insulation roller is disposed on the lower portion of the frame. The two sides of the upper portion of the frame are respectively equipped with one recessed wheel bearing servo-actuator. The distance between the two recessed wheel bearing servo-actuators is consistent with the width of the one-time wiring cross-core row of the automatic detecting wire. The guiding mechanism is additionally arranged, thereby solving a problem that the one-time wiring cross-core rod or the one-time wiring cross-core row is liable to bend and deform during cross-core operation. Meanwhile, an additionally-arranged cross-core guiding drive device helps to realize automation and allows operation to be more accurate. The automatic detecting wire cross-core guiding assembly of the utility model is suitable for automatic detection of a low voltage current transformer.
Description
Technical field
The utility model relates to a kind of guide piece, particularly a kind of low-voltage current mutual inductor automatic Verification line punching guidance set.
Background technology
At present, along with the fast development of China's electric utility, current transformer is widely used as the important component part of electric power meter, and especially the application of low pressure straight-through current transformer is more common.
Must be before metering is used with mutual inductor through using behind the measurement verification department assay approval, the completion of current transformer test board is adopted in the calibrating of estimated current mutual inductor basically, and this test board can realize that 12 examine and determine when only reaching above transformer error.The method of in early days big current lead being passed mutual inductor center hole to be checked, coiling is complicated, and it remains on the center to be difficult to control, is unfavorable for realizing, also can influence measuring accuracy.Primary connection is reduced to primary connection punching bar (60A-750A) or primary connection punching row (750A-2000A) at present, has simplified operating process greatly.But primary connection punching bar or primary connection punching row material are copper, flexural deformation easily in the punching process.
Summary of the invention
In order to solve in the prior art because primary connection punching bar or primary connection punching row material are copper; Cause in the punching process primary connection punching bar or primary connection punching to arrange easy diastrophic problem, the utility model embodiment provides a kind of low-voltage current mutual inductor automatic Verification line punching guidance set.Said technical scheme is following:
A kind of low-voltage current mutual inductor automatic Verification line punching guidance set; Comprise: framework and guiding mechanism; Guiding mechanism is made up of an insulation roller and two recessed wheel bearing followers; The surface of insulation roller is provided with the groove that a circle matches with the primary connection punching shank diameter of said automatic Verification line; Said insulation roller is installed in the bottom of said framework, and the both sides, top of framework are equipped with a recessed wheel bearing follower respectively, and the spacing of two recessed wheel bearing followers is consistent with the primary connection punching row's of said automatic Verification line width.
In the such scheme; This assembly also comprises the punching guide driver; This punching guide driver is a punching guiding cylinder, and the movable end of punching guiding cylinder is fixedly connected with the top of said framework, and this assembly is used to drive framework and guiding mechanism moves to assigned address; With the realization robotization, and operation is more accurate.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: through increasing guiding mechanism, solved in the punching process primary connection punching bar or primary connection punching and arranged easy diastrophic problem; Simultaneously, the punching guide driver of increase is realized robotization, and operation is more accurate.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side-looking structural representation of Fig. 1;
Fig. 3 is the user mode structural representation of the utility model;
Fig. 4 is another user mode structural representation of the utility model.
Among the figure, 1 framework, 2 guiding mechanisms, 21 insulation rollers, 22 recessed wheel bearing followers, 23 grooves, 3 punching guide drivers, 4 primary connection punching bars, 5 primary connection punchings row.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
As shown in Figure 1; A kind of low-voltage current mutual inductor automatic Verification line punching guidance set that the utility model provides; Comprise: framework 1, guiding mechanism 2 and punching guide driver 3; Guiding mechanism 2 is made up of an insulation roller 21 and two recessed wheel bearing followers 22, and the surface of insulation roller 21 is provided with the groove 23 (referring to Fig. 2 and Fig. 3) that a circle matches with primary connection punching bar 4 diameters, and said insulation roller 21 is installed in the bottom of said framework 1; The both sides, top of framework 1 are equipped with the spacing of recessed wheel bearing follower 22, two recessed wheel bearing followers 22 and primary connection punching row 5 width consistent (referring to Fig. 2 and Fig. 4) respectively; Said punching guide driver 3 is punching guiding cylinder; The movable end of punching guiding cylinder is fixedly connected with the top of said framework 1; This assembly is used to drive framework 1 and moves to assigned address with guiding mechanism 2, realizing robotization, and operation more accurately (referring to Fig. 2).
The utility model embodiment is through increasing guiding mechanism 2, solved in the punching process primary connection punching bar 4 or primary connection punching and arranged 5 easy diastrophic problems; Simultaneously, the punching guide driver of increase is realized robotization, and operation is more accurate.
When the utility model used, after the motion of punching mutual inductor put in place, the gas bar motion of dependence punching guiding cylinder drove guiding mechanism 2 and sinks to putting in place; After guiding mechanism 2 moves into place; When primary connection punching bar 4 is come to 2 motions of guiding mechanism; Primary connection punching bar 4 falls in the groove 23 of said insulation roller 21; This groove 23 has been realized the height of primary connection punching bar 4 and the guiding of horizontal level, has also played the jacking effect simultaneously, thereby reaches the situation that prevents that primary connection punching bar 4 from deforming in the punching process; When the primary connection punching arranges 5 when 2 motions of guiding mechanism are come; The primary connection punching is arranged 5 on insulation roller 21; Insulation roller 21 has been realized the guiding of primary connection punching row 5 short transverse; Also played the jacking effect, simultaneously the recessed wheel bearing follower 22 of both sides has been realized the guiding on primary connection punching row 5 the horizontal direction.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
