Current transformer TOL-10 m-15.2 UHL 0.5/2 2500/5 10 p/10 p
Current transformer TOL-10 m-15.2 UHL 0.5/2 10/5 10 p/10 p 3-piece magnet buy in Yekaterinburg from Berezovsky Plant substation.
This transformer is designed for implanting in Switchgears (CREWE) and serves to transmit the signal with measuring information measuring devices and/or device protection and management, as well as to isolate the secondary circuit high voltage connections in electrical devices AC voltage class up to 10 kV, frequency 50 or 60 Hz.
Transformer for differential protection is supplied on request.
Transformer manufactured in climatic design "t" and "Uhl" category properties 2.1 according to GOST 15150 and is designed to work indoors, in accordance with the following conditions:
- height above sea level should be no more than 1000 m;
- temperature Wednesday, taking into account the overheating air inside KRU ― from minus 60° c to + 50° c for execution "Uhl 2.1" and from-10° c to + 55° c for execution "2.1";
- environment nonexplosive Wednesday, containing no dust, chemically active gases and vapours in concentrations destroying metals coating and insulation;
- position ― any.
Transformers are manufactured with a single secondary windings for measurement and one secondary winding for protection. Transformers rated at 1000 and 1500 and can be produced with two secondary windings to protect.
The transformers are equipped with protective transparent lids for separate sealing secondary conclusions.
In transformers current TOL-10 allowed the use of secondary windings for metering, precision class 0 .2s and 0, 5S, with a value of secondary load below 25% of the nominal. The minimum allowable load for winding accuracy class 0 .2s and 0, 5S is 1va airborne hospital helicopter.
In the Passport on current transformers with secondary windings for accounting classes of accuracy 0 .2s and 0, 5S, you specify the measured current and angular error of nominal secondary throttle 1va airborne hospital helicopter.
It is possible to produce transformers with different coefficients of transformation of the secondary windings.
