With the new VACUTAP® VI, MR is tak­ing vac­u­um tech­nol­o­gy to a new lev­el and mak­ing it even more effi­cient and sus­tain­able. This inno­v­a­tive on-load tap-chang­er enables com­pact trans­form­ers for net­work oper­a­tion that were pre­vi­ous­ly unthink­able. A big step for a world that needs more and more ener­gy.

Less is more

Less mate­r­i­al, few­er com­po­nents, less effort in trans­former pro­duc­tion – but max­i­mum effi­cien­cy and more sus­tain­abil­i­ty. With the VACUTAP® VI, the inven­tor of the on-load tap-chang­er is once again set­ting new stan­dards. 

Maximum compactness 

The VACUTAP® VI was devel­oped for pow­er trans­form­ers of up to 100 MVA. It shares the transformer’s oil sys­tem and there­fore takes up sig­nif­i­cant­ly less space than con­ven­tion­al on-load tap-chang­ers. All wind­ing con­nec­tions are locat­ed on one side, which sim­pli­fies the cable rout­ing to the wind­ing and also the instal­la­tion. 

Automatic drive control 

MR offers two con­trol cab­i­net solu­tions for dri­ve con­trol, which can be flex­i­bly posi­tioned direct­ly on the trans­former or exter­nal­ly. The TCC (Tap Chang­er Con­trol) solu­tion is the basic vari­ant that con­trols the VACUTAP® VI effec­tive­ly and reli­ably. The ETOS® ID offers addi­tion­al com­pre­hen­sive func­tions for mon­i­tor­ing and con­trol­ling the trans­former. 

Innovative direct drive 

The inno­v­a­tive DC direct dri­ve con­trols the tap-chang­er elec­tron­i­cal­ly with­out a spring ener­gy accu­mu­la­tor, thus elim­i­nat­ing the dri­ve link­age. An inte­grat­ed pow­er capac­i­tor ensures con­tin­u­a­tion of the switch­ing process even in the event of a pow­er fail­ure. An inno­v­a­tive con­trol algo­rithm com­pen­sates for exter­nal influ­ences such as high oil vis­cos­i­ty. 

There’s a lot in it! 

Effi­cient, sus­tain­able and reli­able – the most impor­tant advan­tages of the VACUTAP® VI at a glance. 

Maximum efficiency

Maximum efficiency 

With the new VACUTAP® VI, man­u­fac­tur­ers can increase the out­put of trans­form­ers by up to 30 per­cent – while main­tain­ing the same space require­ment. Alter­na­tive­ly, trans­form­ers can also be built small­er while main­tain­ing the same out­put. This is made pos­si­ble by the com­pact dimen­sions of the tap-chang­er and a sim­pli­fied wind­ing con­nec­tion, among oth­er things. And since few­er addi­tion­al com­po­nents are required, trans­former pro­duc­tion also becomes sig­nif­i­cant­ly more effi­cient.

Environmentally friendly 

The VACUTAP® VI reduces CO² emis­sions by up to 25 per­cent over its entire life cycle com­pared to con­ven­tion­al vac­u­um tap-chang­ers. It requires 135 kilo­grams less mate­r­i­al and, thanks to its direct dri­ve and shared oil sup­ply with the trans­former, com­po­nents such as dri­ve shafts and pipes can also be elim­i­nat­ed, which means less mate­r­i­al use for trans­former man­u­fac­tur­ers. The MR engi­neers have also opt­ed for high-per­for­mance plas­tics instead of ener­gy-inten­sive alu­minum.

Reliable 

The VACUTAP® VI incor­po­rates the con­cen­trat­ed know-how that MR has gath­ered with vac­u­um tech­nol­o­gy over the last three decades. It was spe­cial­ly devel­oped for net­work oper­a­tion and is main­te­nance-free for up to 300,000 switch­ing oper­a­tions. It has been test­ed in the MR lab­o­ra­to­ry far beyond the stan­dard require­ments. Reli­able arc quench­ing and a fail-safe switch­ing con­cept ensure max­i­mum oper­a­tional safe­ty.

New and already proven 

With the VACUTAP® VI, MR is once again break­ing new ground. And yet this inno­v­a­tive tap-chang­er con­cept already incor­po­rates a great deal of expe­ri­ence that has been proven thou­sands of times in prac­tice. 

Entry into vacuum technology

MR entered the vac­u­um tech­nol­o­gy mar­ket 35 years ago. Since then, it has deliv­ered over 120,000 vac­u­um on-load tap-chang­ers to 150 coun­tries world­wide. 

First resistance tap-changer with vacuum technology

With the VACUTAP® VV®, MR was the first man­u­fac­tur­er to bring to series pro­duc­tion vac­u­um switch­ing tech­nol­o­gy for instal­la­tion inside of oil-filled trans­form­ers. For the first time, this meant main­te­nance-free oper­a­tion for almost all net­work appli­ca­tions.

Common oil system

The ECOTAP® VPD® for dis­tri­b­u­tion trans­form­ers, which also shares the transformer’s oil sys­tem, is switch­ing reli­ably in more than 10,000 appli­ca­tions in over 70 coun­tries. 

Intelligent drives

Since the intro­duc­tion of the first intel­li­gent head dri­ve for pow­er trans­form­ers, over 10,000 units are now in use in 150 coun­tries.
