Road, which will be leaned against in processing procedure, is put into insulating stay to support.It does so and there is following shortcoming：
1st, artificial and equipment cost is high：Insulating stay to be added to do heat dissipation air flue in coiling, be required for shutting down every time and spent
It is time-consuming；
2nd, material cost increases：Insulating stay belongs to insulating materials, increases insulating stay and is increased by insulating materials cost；
3rd, small product size is big：Since insulating stay thickness generally all (is unable to greatly shape not less than 6mm less than 6mm air drag
Into convection current), so interiors of products increases an air flue and increases a size (6mm and more than)；
4th, the whole temperature of product rises lack of homogeneity：Since the width of Wen Shengyu air flues, length and depth have relationship in air flue,
Each airway dimension can not possibly be just the same, so the temperature of each air flue also not sample, the general temperature difference is at 10-30 DEG C.
Utility model content
The purpose of this utility model is that for the above-mentioned insufficient and defect of the prior art, a kind of water cooling three-phase is provided
AC reactor, to solve the above problems.
Following technical scheme may be used to realize in the technical issues of the utility model solves：
A kind of water cooling three-phase alternating current reactance device, including upper yoke, lower yoke and be disposed side by side on the upper yoke, under
First, second, third phase iron core column between iron yoke, be respectively arranged with first in the first, second, third phase iron core column,
Second, third coil, the upper and lower side of first, second, third coil are respectively arranged with outlet row, and the lower yoke bottom connects
Chassis is connected to, the rear and front end of the lower yoke is locked respectively by lower clamping piece and lower fastener, and front and rear the two of the upper yoke
