Description

(RDZ)-series disconnectors for a voltage of 35 kV are designed to switch on and off the de-energized areas of the electrical circuit under high voltage, as well as grounding disconnected areas using stationary grounding switches.

(RDZ)-series disconnectors of a horizontal-rotating type for outdoor installation manufactured in three-pole, two-pole or single-pole configurations conform to the DSTU EN 62271-102 requirements.

Design:

Disconnectors are manufactured as single-pole, two-pole, or three-pole (depending on the order) on a general frame.

Disconnectors are designed as a two-column device with the rotation of the main blades in a horizontal plane. There are the following installation options: three-pole, two-pole, and single-pole. The pole of the disconnector to which the drive is connected is called the leading pole. The pole of the disconnector that is connected to the leading one is called the trailing pole. The leading pole is connected to the drive and to the driven pole with the help of connecting elements on site. Each disconnector consists of a base, insulating columns, a current-carrying system, and a grounding circuit.

The disconnector is operated with the help of an RSM-05-type drive (analog of ПР-05 (manual drive)) and an RSM-07-type drive (analog of ПР-07 (manual drive)),  or an RSD-1-type electromechanical drive (or similar), whereas the grounding blades can also be operated with the help of a motor drive.
