Abstract
The utility model discloses a high-voltage connecting device of a dry-type electric transformer. The high-voltage connecting device of the dry-type electric transformer comprises a first high-voltage connecting rod (4), a second high-voltage connecting rod (5) and a third high-voltage connecting rod (6). The first high-voltage connecting rod (4) is used for connecting an upper connecting terminal of a left side high-voltage coil (1) and a lower connecting terminal of a right side high-voltage coil (3), the second high-voltage connecting rod (5) is used for connecting an upper connecting terminal of a middle high-voltage coil (2) and a lower connecting terminal of the left side high-voltage coil (1), and the third high-voltage connecting rod (6) is used for connecting a lower connecting terminal of the middle high-voltage coil (2) and an upper connecting terminal of the right side high-voltage terminal (3). Upper sections of the first high-voltage connecting rod (4) and the second high-voltage connecting rod (5) are bent upwards, and the lower sections of the first high-voltage connecting rod (4) and the second high-voltage connecting rod (5) are bent downwards. According to the high-voltage connecting device of the dry-type electric transformer, the distances from the branched terminals to the high-voltage connecting rods are increased, and electric discharge is prevented.
Description
Technical field
The utility model relates to the transformer technology field, specifically is a kind of high-voltage connection device of dry-type power transformer.
Background technology
On the 3-phase dry type power transformer, the upper and lower of every group of high-tension coil is respectively equipped with the principal tapping terminal, the one component connecting terminal at the middle part.Now illustrate in Dyn11 tap mode; The dry-type power transformer that connects by traditional connected mode has the following disadvantages: adopt copper rod to connect because most of dry-type power transformer high pressure connects, copper rod is not carried out bending to be handled, when coil height low excessively, copper rod is just very near apart from the distance of tap terminals, cause discharge easily, cause short circuit.
The utility model content
The technical problems to be solved in the utility model is, a kind of distance that increases tap terminals and high pressure connecting rod is provided, and prevents the high-voltage connection device of the dry-type power transformer that discharges.
The technical solution of the utility model is, a kind of high-voltage connection device with dry-type power transformer of following structure is provided, the first high pressure connecting rod that comprises the following splicing ear of the last splicing ear that connects the left side high-tension coil and right side high-tension coil, the 3rd high pressure connecting rod of the following splicing ear of the last splicing ear of the middle high-tension coil of connection high-tension coil and the last splicing ear of right side high-tension coil with the second high pressure connecting rod of the following splicing ear of left side high-tension coil and in the middle of being connected, the epimere of the described first high pressure connecting rod and the second high pressure connecting rod is bent upwards, and hypomere is bent downwardly.
The bend of the described first high pressure connecting rod and the second high pressure connecting rod is 100mm to the distance of end.
After adopting said structure, the utility model compared with prior art, have the following advantages: the mode that adopts bending, distance between high pressure splicing ear and the high pressure connecting rod is increased, prevent discharge, avoid short circuit, though increased a little copper rod consumption, but avoided a lot of hidden danger, reduced unnecessary loss, improved the security performance of transformer.
