JTFY Automaitc Rods Auto Insert & Welding Machine for Transformer Tank Cooler Fin

Transformer Tank Cooler Fin Rods Auto Insert and Welding Machine   is used to weld steel rods on the two sides of   Corrugated Fin   top as below: Corrugated fin transformer tank wall Rods Auto Insert and Welding Machine   can weld two   Steel Rods   and   Fin seams   at one time. automatic rod insertion welding machine corrugated cooler wall welding machine The welded area is smooth and bright. As A accessory machine, JTYF   Rods Auto Insert and Welding Machine   can be operated automatically. Other transformer machine supplier need weld two fins terminals to hold the rods, which is slow and low efficiency. Transformer tank fin rod insert and welding machine ,which set steel rods on corrugated fin top automatically. Then the welding mechanism weld the rod and corrugated fin together. And the corrugated fins seam also be welded. auto rod insert welding machine body Rods Auto Insert and Welding Machine ...

Oil filled transformer test & trial operation

After Oil immersed transformer be installed, we should do testing works as follows: 1. Telemetry of insulation resistance: (1) Telemetry project, high pressure to low pressure and ground (shell), low pressure to high pressure and ground (shell) (2)Select 2500V megohm meter, the appearance of megohm meter should be good, complete shell, flexible shake handle, no long resistance pointer, no glass damage. (3) Open circuit test of megawatt-hour meter, separate two pens, shake the handle of megawatt-hour meter up to 120 y/min, the needle pointing to infinite (∞) is better. Short circuit test: shake the handle of megawatt-hour meter, overlap two than instantaneous, the needle pointing to “0” (zero), indicating that megawatt-hour meter is normal. (4) Qualified value: at 20℃+, the new transformer is not less than 450 MΩ, and the operation is not less than 300 MΩ. This value should not be reduced by 30% compared with the previous value. (5)Absorption ratio R60/R12 should be 1.3 tim...

Corrugated Transformer Tanks Welding Procedure

Corrugated Transformer Tanks Welding Procedure   detail state the   Corrugated Fins Wall Welding  and   Transformer Tank Bottom and Frame Welding . 1 Overview of Corrugated Transformer Tanks Welding This process specification describes the welding requirements and relevant regulations for corrugated tank of distribution transformer. 2. Corrugated Transformer Tanks Welding preparation 1) Drawing preparation and familiarity with drawing requirements. 2) Material preparation Prepare welding materials according to drawings, including bottom, edge and   Corrugated Fins Wall .(The corrugated fin wall is made by   JTFY corrugated fins wall pressing machine , and fins seam weld by   JTFY auto fin wall welding machine .) corrugated wall with bottom embossing Welding wire should be stored in a dry and well ventilated place and kept by a special person. Welding wire, groove and groove should be kept clean in the range of 10-20 mm, and no fore...
