Disconnector horizontal-rotary type with rated voltage 35 kV RG-35
Disconnectors RG-35 with a rated voltage of 35 kV are designed for switching on and off de-energized sections of energized electrical circuits, as well as to ground disconnected sections of the network using built-in grounding knives. Disconnectors are also used to disconnect no-load currents of transformers and charging currents of overhead and cable lines.
Disconnectors are manufactured in single-pole, double-pole and three-pole versions. The pole to which the drive is connected is the leading pole. The drives are designed to operate disconnectors. The rotation of the drive shafts of the main circuit and the grounding circuit is carried out manually, using PR-2B or PRG drives, as well as using a PD-14 motor drive.
Disconnectors are manufactured in the UHL climatic version, placement category 1 according to GOST 15150 and GOST 15543.
The connecting dimensions of the new disconnectors were selected taking into account the possibility of installing them on existing supporting structures of disconnectors of the RDZ series. Disconnectors are two-column devices with contact blades rotating in a horizontal plane.
Disconnectors consist of a main current-carrying system, rotary support insulation, a supporting frame and grounding conductors. The contact blades of the disconnectors are made of copper busbars, to which lamellas made of a bronze alloy are attached. The output contacts are made with transition contact rollers and are hermetically sealed. This ensures stable contact pressure throughout the entire service life and low operating forces on the manual drive handle. The contacting surfaces of the detachable and output contacts are coated with silver. Disconnectors are equipped with polymer or high-strength porcelain insulators.
The electrical insulation strength meets the requirements for disconnectors of 35 kV voltage class according to GOST 1516.3. The creepage distance of the external insulation of serial disconnectors with porcelain insulators is:
- with insulation for pollution degree I – at least 70 cm;
- with insulation for pollution degree II – at least 105 cm.
Disconnectors are not intended to be used under severe vibration, vibration or shock.
