DC contact line disconnector with voltage 3.3 kV RKS-3.3

DC contact network disconnectors RKS-3.3/1250 and RKS-3.3/3000 are designed for switching on and off unloaded sections of the DC contact network of electrified railways, and when operating with a motor drive - also for disconnecting at peak operating hours current voltage of auxiliary machines of electric rolling stock, heating currents of passenger cars and in emergency mode - make-up currents of adjacent substations.
Disconnectors RKS-3.3/1250 are also designed for simultaneous grounding of disconnected sections in the disconnector's open position, using contacts located on the rotary column.
Disconnectors are manufactured in the UHL climatic version of placement category 1 according to GOST 15150-69 and GOST 15543.1-89, and the functionality of the disconnectors must be ensured under the following conditions:
- at an altitude above sea level of no more than 1000 m;
- at the upper operating value of the ambient air temperature plus 40°C;
- at the lower operating value of the ambient air temperature minus 60°C;
- in the absence of ice formation and a maximum wind pressure of 1000 Pa (corresponding to a wind speed of 40 m/s);
- with an ice crust thickness of up to 20 mm and a wind pressure of 140 Pa (corresponding to a wind speed of 15 m/s).
To operate the disconnector, motor drives of the PJ series and manual PRG series are used.
The disconnectors are complete analogues of the disconnectors RKZH, RKM.
