Disconnectors

RD(Z) voltage rating 35, 110, 150, 220, 330 kV

RD(Z) voltage rating 35, 110, 150, 220, 330 kV

Outdoor high-voltage horizontal swinging type disconnectors are meant to build up visible disconnecting spacing in accordance with regulatory requirements and to earthen disconnected sections with the help of earthing devices being an integral part of the disconnectors.

Disconnectors are manufactured as single-pole or three-pole versions (with one master pole) without grounding blades. With one or two grounding blades.

A disconnector consists of the poles composed of the basement, mounting insulating column, main contacts, one or two grounding blades (installed in accordance with a customer requirements) and drive.

Disconnectors with voltage ratings of 110 and higher are delivered with male cutters control motor drive (set up a successor to power transformers drive RPN) and male cutters control manual drive. Male cutters of disconnector for 35 kV are controlled with the help of manual drive. If required by a customer, other arrangement options are possible.

Insulating columns can be manufactured out of porcelain or polymer insulators.

Disconnectors are manufactured as major units and then delivered to a customer for installation on the operation place.

In the design of disconnectors their operating experience in electric power systems is taken into the account. Contact combination units which provide for their reliability and service life increase were upgraded. Drives both motor (have been manufactured by our plant for a long time) and manual have easy design and operational reliability.

Disconnectors are manufactured in accordance with the requirements of International Electrotechnical Commission having regular and reinforced insulation. Climatic versions are N1 and NF1.

Service lifetime is 30 years.

Warranty service lifetime is 5 years.

Disconnectors series RLN

Disconnectors series RLN

Disconnectors series RLN are meant for switching on and off high voltage electric networks under the voltage in the absence of load current in three-phase AC 50 Hz networks.

These disconnectors are manufactured both for domestic and abroad deliveries.

Disconnectors series RLN are meant for switching on and off high voltage electric networks under the voltage in the absence of load current in three-phase AC 50 Hz networks.

Disconnectors series RLNZ are equipped with grounding blades. When grounding blades are switched on network section gets earthed which is required for people protection working on the network.

Climatic version is N.

Placement category is 1 in accordance with GOST 15150 and GOST 15543.

Operating capability of the disconnectors is ensured provided:

  1. wind full pressure is 1000 Pa (corresponds to wind speed 40 m/sec);
  2. wind full pressure in sleet does not exceed 140 Pa (corresponds to wind speed 15 m/sec);
  3. rain rust thickness is not less than 10 mm;
  4. atmosphere type is II under GOST 15150. Ambient medium is explosive-free without conductible dust, corrosive gases and vapor in such concentration that corrodes metal and insulation;
  5. rain intensity is 3 mm/min in accordance with GOST 15150.

Disconnectors provide for minimum allowed distance of:

    • switch on and off:
    • ground fault current is up to 5A;
    • cross current for aerial circuits and cable lines is up to 30A;
    • tripout lines’ loading current is up to 5A.
    • switch off:
    • power transformers’ excitation current is up to 5.5A;
    • aerial circuits and cable lines charging current (capacitive current) is up to 3A.

Disconnectors series RV, RVZ, RVF, RVFZ

Disconnectors series RV, RVZ, RVF, RVFZ

High-voltage three-pole disconnectors series RV, RVZ, RVF, RVFZ with manual drive PR-10 are meant for switching on and off high voltage electric networks under the voltage in the absence of load current in AC 50 Hz networks, voltage 6 kV and 10 kV. These disconnectors are manufactured for national economy needs.

Disconnectors and drives are used as components for packaged switchgear cabinets and single-end service assembled chambers.

Disconnectors can be installed:

  1. vertically;
  2. horizontally;
  3. inclined;

Disconnectors are manufactured with and without grounding blades. Disconnectors with grounding blades are equipped with mechanical interlocking which was manufactured in such way that ground circuit cannot be switched on if main circuit is switched on. And main circuit cannot be switched on if ground circuit is switched on.

Disconnectors are manufactured with phase-to-phase distance from 200 mm or 250 mm.

The drive length can be:

  • 250 mm for disconnectors 630 A;
  • 350 mm for disconnectors 1000 A.
