Description
Technical field
The present invention relates to the device that Transformer Winding compresses winding in process of vacuum drying.
Background technology
Transformer Winding is in process of vacuum drying; Must apply constant thrust to winding; To improve the stability of mechanical Strength for Winding and physical dimension, strengthen the anti-short circuit capability of winding, simultaneously; Can avoid adopting winding after vacuumize, to use coil press machine to compress the operation of winding, to enhance productivity.
At present, the hold down gag that winding adopts in process of vacuum drying is a hydraulic test, though this hydraulic test can apply constant thrust to winding; But this device structure is complicated, and is bulky, costs an arm and a leg; And need to be serviced maintenance; Increased the production cost of Transformer Winding, and the clamping operation of winding on hydraulic test bothers time and effort consuming very much.
Summary of the invention
The purpose of this invention is to provide the dry constant-voltage equipment of a kind of Transformer Winding simple in structure, when Transformer Winding is carried out vacuumize, can apply lasting and constant thrust winding.
The dry constant-voltage equipment of Transformer Winding according to the invention; Comprise platen, following platen, pull bar, force transmission rack and foot rest, said foot rest has three at least, and its outer end is equipped with roller; It is inner hinged with force transmission rack; Foot rest is evenly arranged on the force transmission rack, the inner of foot rest also through bearing pin and strip pin-and-hole with to press down tray bottom hinged, make foot rest and force transmission rack be positioned at time platen under; The pin joint of foot rest and following platen between the pin joint and roller of foot rest and force transmission rack, and the pin joint of foot rest and following platen apart from the distance of roller greater than the pin joint of foot rest and following platen distance apart from the pin joint of foot rest and force transmission rack; The outer end of force transmission rack is set on the lower end of pull bar, and the pull bar lower end is connected with nut, and is positioned at the force transmission rack below, and directly over the platen, it was set on the pull bar upper end under last platen was positioned at, and the pull bar upper end is connected with nut, and is positioned at the platen top.
Said upper and lower platen is the circular discoid body; Said force transmission rack is a cross; Be wholely set four first articulated slabs that are the cross layout at the force transmission rack center; Four first articulated slabs are positioned at the plane at force transmission rack place, and its integral body is put up 45 ° of angles with power transmission, and foot rest is inner hinged through first articulated slab and force transmission rack; Bottom surface at following platen has been wholely set four second articulated slabs; Offer the strip pin-and-hole on it; Foot rest is inner hinged through this strip pin-and-hole and bearing pin and second articulated slab, and said pull bar has four, and upper and lower platen lays respectively at the two ends up and down of pull bar and between four pull bars.
Be welded with spacing axle sleeve in the force transmission rack center upper surface, be welded with spacing collar pressing down disk center, spacing axle sleeve is positioned at spacing collar and spacing collar matched in clearance, presses moving radially of relative force transmission rack to limit down platen.
The clamping of Transformer Winding on this hold down gag operated as follows:
To go up platen earlier and take off, Transformer Winding will be placed on down on the platen, put platen again, and make winding between upper and lower platen, screw on the nut (this moment, nut can be screwed) of pull bar upper end then from this hold down gag.With driving lifting this hold down gag (lifting rope of driving is connected and presses down plate edge), make this hold down gag unsettled.Foot rest is sagging because of self gravitation in this process, and drives force transmission rack and move up, and afterwards the nut of pull bar lower end is screwed, and winding is clamped between the upper and lower platen.Then with this hold down gag handling to the vacuum drying tank flatcar, and put down.Hold down gag is in putting down process, and the roller of foot rest outer end contacts to earth, and along with the decline gradually of hold down gag, the inner of foot rest is surperficial near the vacuum drying tank flatcar gradually, thereby foot rest is rotated, and is placed on the vacuum drying tank flatcar until hold down gag.In this process; Force transmission rack moves down with hold down gag; The pin joint of foot rest and force transmission rack rotates (bearing pin slides in this process) around the hinging pin shaft of foot rest and following platen in the strip pin-and-hole simultaneously, the distance between force transmission rack and the following platen is increased, thereby the nut that makes force transmission rack pass through its below spurs pull bar downwards; Pull bar will be gone up platen to pressing down through the nut of last platen top again, thereby winding is pressed between the upper and lower platen.
Because the suffered thrust of Transformer Winding is caused by hold down gag according to the invention and winding self gravitation; So this thrust is lasting and constant; According to lever principle; The suffered thrust of winding is the multiple of hold down gag and winding self gravitation, so winding is compressed in vacuumize reliably.This hold down gag only is made up of limited several parts, and with respect to hydraulic test, structure is very simple, and installation cost is extremely cheap, and the clamping of winding is simple to operation.
