Disconnectors РЛН(RLN) series

Disconnectors РЛН(RLN) series

   Disconnectors of the РЛН(RLN) series are designed to turn on and off under voltage sections of a high voltage electrical circuit in the absence of load current in three-phase alternating current networks with a frequency of 50 Hz.

   Manufactured for domestic and export deliveries. Disconnectors are designed to turn on and off under voltage sections of the high voltage electrical circuit in the absence of load current in alternating current networks with a frequency of 50 Hz.

Disconnectors of the РЛНЗ(RLNZ) series have grounding blades, when turned on, the line section connected to the disconnectors from the side of the grounding blades is grounded, which is necessary to ensure the safety of people working on the line. Climatic version - У; Placement category - 1 in accordance with ГОСT 15150 and ГОСT 15543. Our plant produces the following РЛН(RLN) disconnectors:

РЛН-10/400(630) У1, РЛНЗ-10/400(630) У1.

The operability of disconnectors is ensured under the following conditions:
1. maximum wind pressure - 1000 Pa (corresponds to a wind speed of 40 m / s);
2. maximum wind pressure in ice - no more than 140 Pa (corresponds to a wind speed of 15 m / s);
3. when an ice crust is formed with a thickness of not more than 10 mm;
4. atmosphere of type - II according to ГОСT 15150.
5. The environment is not explosive, does not contain conductive dust, corrosive gases and vapors in concentrations that destroy metal and insulation; rain intensity is 3 mm / min in accordance with ГОСT 15150.
Disconnectors provide at the minimum permissible distance:
disable and enable:
earth fault currents - up to 5 A
equalizing current of air and cable lines - up to 30 A
load current of disconnection lines - up to 5 A
shutdown: magnetizing current of power transformers - up to 5.5 A
charging current of air and cable lines (capacitive current) - up to 3A.
