Installation and commissioning of on-load tap-changers

(1) The quality of storage prior to installation will affect the installation quality of the on-load tap-changers. Because the contact is oxidized in the air, and some insulating materials especially the paper insulation in the air may be cracking and deformation, so there is my tap-proof preservation of the switch is very important.

(2) The division of the wire can not be too much force. If the force is too large, then the switch itself and contact the single side of the force is too large, easy to cause sealing leakage, contact not in place and so on.

(3) Drying treatment. Because of the small density of the switch, and most of the use of epoxy resin materials, the water is very small, not with the transformer body synchronous drying, which can avoid high-temperature, especially the coal-gas phase drying 135° high temperature infringement, to prolong the service life of the switch is beneficial.
