Product Description

Overview

Function
This machine is special-purpose unit for body assembly for amorphous alloy transformer, it is used for various specs of oil-immersed and dry-type transformers. It has changed the traditional process, the coils are pre-placed on the lift platform of assembly stand, the winding axis is horizontal, each single-frame core cross through winding inner hole. And can complete the core folding, bandaging, the body insulation assembly, clamps fastening and other processes. The height of assembly stand can be adjusted easily to meet the requirements in different steps of the assembly process.
The main movement mechanism uses hydraulic system, with features of stable lift, easy adjustment, redundant power and so on.

Operation instruction
3.1Power-on, turn on power switch, then the unit is in working state.
3.2 Following the workpiece specifications:
* Adjust the left and right hand wheels on the front of assembly stand ,pre-set the width of the work table, the pre-set width is the height of winding axial plus extra 5 mm for winding easy hanging.
* Adjust the left and right pressure holding brackets on the assembly table, allow the distance between the two pressure plates longer than max length of the body.
* Operate the lift ,make the three "V" brackets on the lift slightly higher than the working platform ,and adjust the distance between the three brackets according to the size of the body. Then lock them after adjustment.
* Hanging A, B, C three-phase coils on the bracket in turn, the coils of the long axis is vertical to the work plane. Adjust the handwheel on the bracket, press the plate against the side of the coils gently to ensure the winding vertical crossing through the core and safety.

* Low the lift platform slowly, allow the inner plane of short axis of the winding is slightly lower than the working plane by about 5 mm. And then place the end insulation of the body.
* Hang the core on the auxiliary mobile trolley. The core can be adjusted to the winding position with the manual hydraulic jack.
* After inserting the first layer main and sub-frame core into the winding in turn, fold the cores on the other side of assembly stand, painting epoxy and binding up. Operate the lift down to keep the upper plane of first layer core parallel to the fixed working plane ,then start to insert and assembly the second layer core. In the process, in order to avoid the displacement deformation of the core and the damage due to press , the temporary support tool shall be used to support the impending part of the core.
* After installing the body insulation, assemble the upper and lower clamp, left and right side plates, then fastening according to process requirement. Complete the body process and lift away by crane.
* Electrical protection devices are equipped in the limit parts to prevent malfunction and ensure safety.

Main structure:
The lift adopts hydraulic system , it includes: oil pump, motor, kinds of  valves, etc., high-quality parts are used to ensure high reliable, low noise and non leakage system. Rated working pressure 14 Mpa. Use high-pressure hose connection, safe and easy operation.
* Design large-scale lifting platform, (1400 × 670 mm) to meet movement space for various bearing mechanism and sliding table. At the same time, leave enough margin to facilitate the support operation.
* The movement method for sliding bearing table using pulley driving, with strong load-bearing ability, portable operation, accurate positioning. The bearing table can be raised and lowered to the range of 100 mm, which can meet the usage requirements. The fine-tuning mechanism equipped a plane bearing to reduce the manipulation strength of the adjustment when heavy loaded.
* The front fixed platform equipped screw- bar drive mechanism, move the fixed platform straight or back by turning the hand wheels. After the platform to the working position, lock the platform by pulling handle.
* The press-contact mechanism is installed on the left and right sides of assembly stand to hold the winding and iron core and ensure the safety at the same time. The effective stroke of each press mechanism is 500 mm.
* The main electronic components are used Schneider products to ensure high reliability.
