Constantly improve and development along with ac variable speed technology, owing to its energy conservation and consumption reduction effects is notable, alternating-current actuating system is in industrial circle, particularly it is used widely in the industries such as metallurgical, coloured, building materials, all newly-built on a large scale or transformation project, top-priority is all alternating-current actuating system.For reducing the harmonic current in electrical network, use converter must be powered by isolating transformer.Chinese utility model patent CN103440971B discloses a kind of AC converter isolating transformer, reduces the hardware cost of isolating transformer.But, the transformator of this structure, in use owing to tank temperature changes greatly, so needing the fuel reserve tank that configuration volume is bigger, brings inconvenience to installation and use.
Utility model content
The technical problems to be solved in the utility model is to provide the AC converter isolating transformer of a kind of improvement, it is possible to solves the deficiencies in the prior art, reduces the dependency for fuel reserve tank.
For solving above-mentioned technical problem, technical solution adopted in the utility model is as follows.
A kind of AC converter isolating transformer of improvement, including fuel tank main body, it is provided with in fuel tank main body and is respectively fitted in a conjugation iron core column unit and the first winding in lower unit and the second winding, it is provided with insulation board in described fuel tank main body, it is flexibly connected by the first rubber bellows set between adjacent insulation board, insulation board is provided with several through holes, fuel tank main body is provided with and through hole radiating tube one to one, it is connected by the second rubber bellows set between through hole with radiating tube, it is provided with choke in the middle part of second rubber bellows set, the inner side of choke is provided with spring leaf, spring leaf and choke fit tightly, all radiating tubes are all connected with the return duct at fuel tank main body top, it is positioned on the insulation board at fuel tank main body top and is provided with return port, return duct and return port are rigidly connected.
As preferably, the arranged outside of described radiating tube has several heat radiation sleeve pipes, and heat radiation sleeve pipe is connected with radiating tube, and fin runs through the sidewall being arranged on heat radiation sleeve pipe.
As preferably, the junction of described radiating tube and return duct is provided with impeller.
What employing technique scheme was brought has the beneficial effects that: this utility model is by arranging the insulation board of activity, fluid in fuel tank can be cushioned, thus reducing the demand for fuel reserve tank inner fluid by moving of insulation board when volume changes.Entering radiating tube by through hole when fluid is heated, then pass through return port backflow, fluid dispels the heat in radiating tube.When the insulation board generation change in location that activity is arranged, spring leaf can be driven to produce elastic deformation, so that the internal diameter of choke produces change, it is achieved the real-time change of fluid flow, improve radiating efficiency.Heat radiation sleeve pipe can improve the radiating efficiency of radiating tube, when fluid flow to impeller place, under the drag effect of impeller, produce extra flow resistance, thus extending fluid flowing time in radiating tube and heat radiation sleeve pipe, further increase radiating efficiency, reduce the expansion volume of fluid.
