Water path collecting pipe for internal water cooling phase-shifting transformer

Abstract

The invention relates to the technical field of electrical equipment manufacturing, in particular to a water path collecting pipe for an internal water cooling phase-shifting transformer. The water path collecting pipe is characterized by comprising a collection header pipe (1), a plurality of collection branch pipes (2) and a plurality of water path connectors (5); one end of each collection branch pipe (2) is communicated with the collection header pipe (1), one end of the collection header pipe (1) is sealed, and the other end of the collection header pipe (1) is provided with a flange (3); the water path connectors (5) are welded to the collection branch pipes (2) and communicated with the collection branch pipes (2). According to the water path collecting pipe, all cooling water branches in the internal water cooling phase-shifting transformer are connected in parallel for operation, and the water path collecting pipe has the advantages that the cooling water flow resistance is small, the cooling effect is good, the water supply pressure is low, and the product is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electric equipment manufacturing, and more specifically relates to a water channel confluence pipe for a phase-shifting transformer with internal cooling in water. Background technique [0002] With the continuous development of technology, water-cooled phase-shifting transformers have been continuously applied in the high-voltage inverter industry. Due to the large number of cooling water branches of the water-cooled phase-shifting transformer, the length of a single branch is relatively long. If the cooling water branches are connected in series to the water cooling system, it has the following disadvantages: long water path, high flow rate, and large flow resistance. , high temperature, high water supply pressure, poor reliability and high cost. Contents of the invention [0003] In order to overcome the defect that each cooling water circuit runs in series, the invention provides a water circuit co...
