ТОП-0.66 and ТШП-0.66 CURRENT TRANSFORMERS

Transcription

1 ТОП-0.66 an ТШП-0.66 CURRENT TRANFORMER ТОП-0.66 an ТШП-0.66 current transformers are intene for transmission of measuring signals to measurement evices an are applie in electricity metering an counting circuits of a.c. installations of 0 z frequency an up to 0.66 kv (inclusive) rate voltage. Transformers comply wit te requirements of GOT 6- stanar. Climatic version CT as in accorance wit IEC :2 stanar. Transformers are resistant to externally inuce mecanical stresses as for M2 mecanical performance group in accorance wit GOT an are rate for installation at te altitue of not more tan 000 m above sea level. As to installation conitions on worksite, te transformers are incorporate ones an tey allow to be installe in watever attitue position. Insulation termal-enurance class E as to GOT Magnetic cores of te ; 0.2 an 0.2 accuracy class current transformers for 0 A primary currents are of two esigns: - mae of electric steel; 2 - composite type mae of electric steel an nanocrystalline alloy. Magnetiс cores of 0.2 an 0.2 accuracy class are of te 2n esign multiple-unit of electric steel an nanocrystalline alloy. Inex of magnetic core esign variant is inclue into te transformer esignation. Winow type current transformers ТШП-0.66 for 0 A primary currents are of two esigns epening on winow size: -I - 23x03 mm (current transformers for A primary currents); -II - 38x8 mm (current transformers for 000 A primary currents); -III - 60x3 mm (current transformers for A primary currents). Magnetic cores of transformers are mae of electric steel. Te winow esign variant number also is a part of ientification coe of current transformer. econary wining contact terminals are covere wit a transparent plastic cap, wic, if necessary, can be seale up. Transformers are subject to inspection by te Public tanars Boy representatives. ТОП-0.66 an ТШП-0.66 current transformers esign provies ouble contact terminals allowing to carry out control cecks at facilities witout loa-off an, for ; 0.2 an 0.2 accuracy class a seale-up contact terminal for connection to a counter coil, wic prevents electricity stealing. tructural parts of te transformers cases are mae of arly ignitable plastic. As to protection against electric-sock azar te transformers belong to 0 class in accorance wit GOT an ave IP00 protection egree in accorance wit GOT
