Disconnector horizontal-rotary type with rated voltage 110 kV RG-110
Disconnectors RG-110 are designed to turn 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-6: PR-180 drives, or PD-14 motor drive.
A distinctive feature of the RG is the design of the main knives. The contacts of the main knives and grounding knives are made of bronze alloy and have a special configuration that ensures uniform pressure and high-quality electrical contact, which allows for flawless operation during the entire service life of the disconnectors, because Bronze, according to its physical and chemical characteristics, does not change its given shape. Contact connections of the main knives equipped with anti-ice covers. The contacts work well in extreme weather conditions with ice thicknesses up to 20mm
The bases of the pole columns use maintenance-free sealed bearing units, which ensure the reliability of the rotating units of the contact system. One of the columns of the device is made fixed, which reduces the number of kinematic connections and increases the reliability of the product.
Disconnectors are manufactured in the UHL climatic version, placement category 1 according to GOST 15150 and GOST 15543.
The electrical insulation strength meets the requirements for disconnectors of 110 kV voltage class according to GOST 1516.3-96. The creepage distance of the external insulation of serial disconnectors with porcelain insulators is:
- with insulation for pollution degree I – at least 200 cm;
- with insulation for pollution degree II – at least 250 (280) cm;
- for polymer insulation – at least 250 (280) cm.
