Explicação, anotação:

To protect electric equipment of transformer station and ac networks hour òîòîé 50 cycles from atmospheric and short-term switching surge voltages

Descrição porminorizada da marca:

The active part of clippers consists of in series with zno resistors with high linear voltage-current õàðàêòåðèñ teak. the internal cavity of tyre with resistors shall be filled in heat-conductive composition. The protective effect can be explained by the fact that in case of appearing is dangerous ãî for over-extension insulation elapsing through impulse limiter the humanitarian aid current because of high non-linearity of resistors shall not create dangerous for insulation of voltage rise. priority - low protective level for all types over-extensions - high energy intensity - enhanced resistance to effects pollution - explosion safety and seismic resistance small sizes and mass technical characteristics class of network voltage, apartment. 0, 38 maximum operating voltage, apartment. 0, 4 voltage on clipper, kW 20 minute. 0, 48 20 S.. 0, 53 1 S.. 0, 65 0, 15 S.. 0, 7 nominal discharge current, K.. 2, 5 design current of commutation over-extension at a wavelength of 30/60 usec, A.. 125 discharge voltage in case of design current switching overvoltage, not more, apartment. 1, 3
