Disconnectors RLND-1-10/200 U1, RLND-1-10/400 U1, RLND-1-10/630 U1 (polymer)

Description

Designed to create a visible break in the electrical circuit in order to ensure safe servicing of electrical equipment;

• for switching on and off de-energized sections of a high-voltage circuit;
• Grounding of disconnected sections using stationary grounding conductors;
• to switch off and on the no-load current of transformers;

The PRNZ-10 drive is designed for manual switching on and off of the main and grounding knives of disconnectors.

Main technical data of disconnectors RLND-1-10-200 U1, RLND-1-10-400 U1, RLND-1-10-630 U1

The disconnector is a two-pole or three-pole device, each pole of which has one fixed and one movable column, with the main knives turning in the horizontal plane.

The disconnector drive is designed so that it excludes the possibility of operating the grounding switch until the knives of the main circuit are disconnected. The drive body has openings for installing a block lock.

The isolation switch insulation consists of four or six insulators, two or three of which are mounted on levers and the rest on channels.

The current-carrying system, made in the form of two contact blades, is installed on the upper flanges of the disconnector insulators. The general appearance, overall, installation and connection dimensions of the disconnectors are shown in Fig. 1.
