The utility model discloses the technical scheme who adopts is slidable frock for support column type current transformer welding process, including slidable welding fixed plate, a conductor upper fixed plate, a conductor bottom plate and cushion, a conductor upper fixed plate be connected with slidable welding fixed plate's upper end for fixed a conductor upper end, a conductor bottom plate be connected with slidable welding fixed plate lower extreme for fixed a conductor lower extreme, slidable welding fixed plate's upper end open and to have the spout, a conductor upper fixed plate card in the spout, and reciprocate in the spout, the spout bottom is arranged in to the cushion, cushion upper end bearing primary conductor upper fixed plate, the lower extreme top of cushion leans on the bottom at the spout.

In the preferred embodiment of the present invention, the primary conductor has edge notches at both ends of the upper fixing plate, and the edge notches are engaged with the groove edges of the sliding groove.

The technical effects are as follows: the upper fixing plate of the primary conductor can easily move up and down, and the position size of the primary conductor can be ensured.

In the preferred embodiment of the present invention, the primary conductor upper fixing plate and the primary conductor lower fixing plate are respectively connected to each other by four sets of bolts.

The technical effects are as follows: the position size after the primary conductor welding is ensured, and the deviation cannot be too large.

In a preferred embodiment of the present invention, the cushion block has a square structure.

The technical effects are as follows: the structure is simple, and the fixing plate on the primary conductor can be rapidly moved down when in use.

The utility model has the advantages that: because adopt the utility model discloses a frock is used in welding, support type current transformer is when welding primary conductor, because secondary coil keeps away from the welding department, so the temperature that produces when heating primary conductor can not lead to the fact the influence to secondary coil's quality, and this technology has reduced manufacturing cost, improves production efficiency, and the secondary coil condition such as short circuit, insulation breakdown have been appeared in very big having avoided, have guaranteed novel current transformer's quality.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of the embodiments of the present invention, as generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

The utility model discloses a concrete structure includes: the device comprises a slidable welding fixing plate 1, a sliding chute 2, a primary conductor upper fixing plate 3, a primary conductor lower fixing plate 4 and a cushion block 5; the primary conductor 6 is divided into an upper end and a lower end, a copper rod is additionally arranged in the middle of the primary conductor 6, the primary conductor 6 of the strut type current transformer is connected with the slidable welding fixing plate 1 through a primary conductor upper fixing plate 3 and a primary conductor lower fixing plate 4, the upper portion of the slidable welding fixing plate 1 is provided with a sliding groove 2, the sliding groove 2 penetrates through the upper side face of the slidable welding fixing plate 1, the whole structure is in a cuboid hole shape, the primary conductor upper fixing plate 3 is of a structure with a side notch 8 and is clamped into the groove edge of the sliding groove 2, the sliding groove 2 can move up and down, the primary conductor upper fixing plate 3 and the primary conductor lower fixing plate 4 are connected with the primary conductor 6 through four groups of bolts, a cushion block 5 is arranged at the bottom end of the primary conductor upper fixing plate 3, the bottom of the cushion block 5 is in contact with the bottommost end of the sliding groove 2, the cushion block 5 blocks the cushion block 5, the cushion block 5 supports the primary conductor upper fixing plate 3 and moves the primary conductor upper fixing plate 3 upwards, and the distance of the primary conductor upper fixing plate 3 is equal to the height of the cushion block 5.
