Detailed Description
First, it should be noted that the specific structures, features, advantages, etc. of the present invention will be specifically described below by way of example, but all the descriptions are for illustrative purposes only and should not be construed as limiting the present invention in any way. Furthermore, any single feature described or implicit in any embodiment or any single feature shown or implicit in any drawing may still be combined or subtracted between any of the features (or equivalents thereof) to obtain still further embodiments of the utility model that may not be directly mentioned herein. In addition, for the sake of simplicity, the same or similar features may be indicated in only one place in the same drawing.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or orientations or positional relationships that the products of the present invention are conventionally placed in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the description refers must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The present invention will be described in detail with reference to fig. 1 to 4.
As shown in fig. 1-4, the zero sequence current transformer convenient for a cable to pass through includes a first fixing seat 1 and a second fixing seat 2, where an iron core 3 is fixedly sleeved in both the first fixing seat and the second fixing seat; the first fixing seat is also fixedly connected with a cylindrical insertion rod 7, a notch 8 is formed in the position, corresponding to the insertion rod, of the second fixing seat, and an internal thread 9 is formed in the inner wall of the notch; the inserted link is further sleeved with a rotating ring 10 through a bearing 12, and the outer wall of the rotating ring is further provided with an external thread 11;
the inserted bar end inserts in the notch to make through rotating the circle passes through external screw thread and the intraoral internal thread connection of notch, and fixed connection is realized with the second fixing base to first fixing base, and the iron core in first fixing base and the second fixing base contacts each other.
In order to make the first fixing seat 1 and the second fixing seat 2 more stable when forming the zero sequence current transformer, it can be considered that a sliding rod 5 is further fixedly arranged on the second fixing seat, a sliding groove 4 is formed in the position of the first fixing seat corresponding to the sliding rod, the tail end of the sliding rod is inserted into the sliding groove, the limiting effect through the sliding rod is achieved, and a damping spring 6 is further installed at the bottom end in the sliding groove, so that the vibration can be reduced when the first fixing seat 1 and the second fixing seat 2 are installed, and the damage is avoided.
