Description
Power: 300 . . . 600 A
Voltage: 10 kV
Warranty: 3 years.
Purpose: Current transformers TOL - 10, accuracy classes 0.2S; 0.5S; 0.5; 5P; 10P are intended for installation in complete switchgears (KRU) and are used to transmit the signal of measuring information to measuring devices and protection devices in electrical installations of alternating current of voltage class 10 kV and frequency of 50 Hz.

Current transformers TOL - 10, accuracy classes 0.2S; 0.5S; 0.5; 5P; 10P are intended for installation in complete switchgears (KRU) and are used to transmit the signal of measuring information to measuring devices and protection devices in electrical installations of alternating current of voltage class 10 kV and frequency of 50 Hz.

Transformers are made in basic design.

Transformers are manufactured in the UHL 2.1 climatic version in accordance with GOST 15150 - 69 and are designed for indoor operation in the following conditions:

  • height above sea level no more than 1000 m;
  • ambient temperature, taking into account air overheating inside the switchgear, from minus 60 ° C to plus 50 ° C;
  • non - explosive environment, free of dust, chemically active gases and vapors in concentrations that destroy metal coatings (type II atmosphere in accordance with GOST 15150 - 69);
  • nominal operating values of mechanical external influencing factors for the group of mechanical performance M5 in accordance with GOST 17516.1 - 90.

Any working position of transformers in space.

Transformers are available with two or three secondary windings.

The terminals of the secondary windings of the transformers are covered with transparent covers that can be sealed.

In transformers with two secondary windings, winding No. 1 is intended for measurements and metering, winding No. 2 is for protection circuits. In transformers with three secondary windings, windings No. 1 and No. 2 are intended for measurement and metering, winding No. 3 is for protection circuits.

The lower limit of the secondary load for windings of accuracy classes 0.5S and 0.2S is 25% of the rated value.

The primary and secondary windings of the transformers are filled with epoxy compound, which provides electrical isolation and protection from external influences.
