Rectifying plants of atmospheric ice melting with direct current

Rectifying plants of atmospheric ice melting with direct current (RPAIM) and mobile plants of ice melting with direct current (MPAIM) for the rated voltages of 0.4 ÷ 50 kV three-phase alternating current with a frequency of 50 Hz with capacity of up to 60 MVA are intended for melting atmospheric ice on wires and grounding wires.

RPAIM (MPAIM) are used at electric grid facilities, in power supply systems of industrial enterprises, gas and oil-producing industries, at rural and urban facilities, and also in railway transport.

          RPAIM (MPAIM) distinguishing features

  • RPAIM (MPAIM) is a product of maximum operational readiness.
  • Mobility and transportation ease.
  • Possibility to install remotely from the existing power sources.
  • Convenience of assembling and operation.

RPAIM (MPAIM) operation conditions

  • RPAIM (MPAIM) climatic version and placement category is Y1 (YXL1) in accordance with GOST 15150-69;
  • ambient air temperature from -60° C to +40° C;
  • type II atmosphere – industrial, environment – non-explosive, free of dust in concentrations that reduce the product parameter, air relative humidity up to 80% at the temperature of 20ºС;
  • installation altitude above sea level is no more than 1000 m;
  • wind speed up to 36 m/s (wind pressure up to 80 daN) in the absence of atmospheric ice, wind speed up to 15 m/s (wind pressure up to 14 daN) with the atmospheric ice with its thickness of 20 mm;
  • seismic resistance is 8 points per MSK- 64.

RPAIM (MPAIM) complete set

RPAIM (MPAIM) is a set of equipment of full factory readiness, consisting of one or more modules: of the rectifier module of the controlled atmospheric ice melting, of the diesel generator unit (DGU) module and the Packaged Transformer Substation (PTS) module. Each module includes a separate mobile platform, providing substation mobility, in the mobile version.

The DGU and PTS modules are supplied to provide power for the rectifier module for controlled atmospheric ice melting. These modules are not supplied if there are existing power sources at the facility.
