TECHNICAL DATA TYPE CVT VACUUM ON-LOAD TAP CHANGER FOR DRY TYPE TRANSFORMER HM0.154.001 SHANGHAI HUAMING POWER EQUIPMENT CO., LTD.

1. General Type CVT vacuum on-load tap changer (hereafter refer as CVT or CVT OLTC) is a combined structure on-load tap changer, It comprises of diverter switch and tap selector. The tap selector changes tap from one to the adjacent without carrying current, and then the diverter switch switches under the load, the vacuum interrupters work as arcing contacts, which enables reliable performance and long life expectancy. CVT OLTC is applicable to dry type transformer with voltage up to 12kV, the max. rated through current 160A, linear regulation up to 9 operation positions, regulation at any winding...

Table 1 CVT OLTC Technical Specifications Note: Please contact with us for special requirement. 4.2 Step voltage Rated step voltage (U,) For each value of rated through-current, the highest permissible voltage between terminals which are intended to be connected to successive taps of the transformer. Maximum rated step voltage (Uim) The highest value of the rated step voltage for which the tap-changer is designed. TYPE CVT VACUUM ON-LOAD TAP CHANGER TECHNICAL DATA

4.3 Step capacity Step capacity is the product of step voltage and load current, that is Ps=UI. Rated step capacity is the maximum permissible step capacity for the tap changer under continuous working condition, that is P stN=Ium×Ui. For a certain range of load, its rated step capacity can be represented by the range curve shown in Fig. 1. This range is defined by the maximum rated through-current on the horizontal axis and maximum permissible step voltage on the vertical axis. Loads within the defined curve is the rated values of the tap changer. Fig1 Correlation between Rated Step Capacity,...
