Vacuum On-Load EPTp Changers For Oil Immersed Transformers change
CM2 OLTC
EPT
CM2 on load tap changer (Hereafter, referred to as OLTC) applies to EPT and rectification transformers with
highest voltage of 72.5kV,126kV,170kV and 252kV, maXiHu (West Lake) Dis.mum rated via recent of 600A for three phases
and 1500A for solitary phases, to adjust the taps below load for the function of voltage regulation. A few section
OLTCs are used at the EPT level of Y connection, and solitary stage OLTC can be employed for any
connections.
CM2 OLTC is a standard OLTC of blended composition, consisting of diverter change and tap selector.
CM2 on load faucet changer is to be mounted to the transformer tank cover by its faucet changer head which serves
also for connecting to the motor EPTr CMA7 or SHM-III through the worm EPT box and EPTl EPT box to EPT faucet
change procedure.
When CM2 OLTC is utilized with out a alter-in excess of selector, the maXiHu (West Lake) Dis.mum operating positions accessible will be 18,
and 35 positions with a changeover selector. (EPT design and style is excEPTd).
This operation recommendations incEPTs all the essential information for the installation and operation of CM2
OLTC. CM2 EPT OLTC has the exact same total dimension as CM kind OLTC.
Variety designation
The operating issue of OLTC
The temperature of oil unEPTwhich the faucet changer operates have to not exceed one hundred ordmC and not reduced than
-twenty five ordmC .
The ambient temperature all around the faucet changer need to not exceed forty ordmC and not reduced than -25 ordmC .
The non-perpendicularity of OLTC on the transformer in opposition to ground degree should not exceed 2%
The room for mounting OLTC ought to be cost-free from significant dust and other explosive and corrosive gases.
The mechanical life of OLTC must not be much less than 1,five hundred,000 functions.
The mechanical lifestyle of OLTC need to not be much less than 1,500,000 functions.
EPT procedure basic principle of the tap changer
EPTp change operation starts with the electrical motor of the motor EPT device. The driving pressure is transferred to
the worm EPT box on the prime go over of the faucet changer via driving shaft and belt pulley box,then the power
is actuated to the vitality accumulating system and the shaft which passes through the diverter change sown
to the cylinEPTbottom.
There the cylinEPTbottom EPT clutch is connected to the Geneva wheel mechanism of the tap selector. The
rotation of Geneva wheel tends to make the getting in contact with bridge to rotate an angle corresponding to one phase, therefore the
connecting bridge will be related to the desired faucet of the faucet winding with no load.
Transportation of transformer collectively with the faucet changer
When the faucet changer is assembled to the transformer, mindful thought shall be offered to the basic safety of
transportation (for illustration, to offer the short term supporting). If the faucet changer is immersed type, it is not
necessary to take away it for transportation. If there is difficulties which requires to dismantle the motor EPT device, it
must be loosened at the placing placement, so that it can be transported in the horizontal position. After arriving
on website, the motor EPT unit can be re-installed according to above described.
If the transformer is transported or saved with out the conservator, then the bypass pipe (see Appendix 9)
supplied by our factory can be put in in between the oil filling flange of the faucet changer and the overflow pipe
flange of the transformer (the place of the flange is revealed in the Appendix1), so that the static stress
caused by the oil growth can be balanced.
If transformer is essential to be transported or saved with no oil filling, then the oil in the oil compartment of the
diverter change need to be completely drained. The bypass pipe have to be put in at that time so that the oil
compartment and the transformer oil tank will be subjected to the same stress (nitrogen sealing).
In orEPTto avoid damaging the faucet changer caused by the displacement of relocating areas, they have to be
quickly secured.
Observe: The bypass pipe shall be taken off from the faucet changer head when the transformer is
put in onsite and just before putting it into operation.
EPT
The tap changer and the motor EPT device are packaged separately for shipping and delivery following they have been executed
routine test and set at the specified situation.
Upkeep time period
It is cost-free routine maintenance for 300,000 operations.
