Purpose of RDZ disconnectors
The RDZ external disconnectors are intended for inclusion and shutdown of deenergized sites of electric network of high voltage, and also grounding of the disconnected sites by means of the stationary grounding knives.
Design of RDZ disconnectors
RDZ disconnectors consist of separate poles which can be used in unipolar and three polar option of installation on the horizontal plane. RDZ-35 disconnectors and RDZ-110 Disconnectors on a class of tension of 35 and 110 kV on rated current 1000 A allow installation on the vertical plane. The pole razjedinitelyavypolnen in the form of the dvukhkolonkovy device with a turn of the main knives in the horizontal plane also consists of a socle, insulating columns, current carrying system and the grounding device.
Contact knives of the disconnector on 1000A are executed from two copper parallel tires installed "on an edge" which one end is connected by flexible communications to a contact conclusion, and on another the demountable contact is formed. Contact knives of RDZ disconnectors on 2000 and 3150A consist of two contact knives on 1000A. The grounding knives which are permanently established on a tsokolerazjedinitel of RDZ and the motionless contact come on the main contact knife enter the grounding device of the disconnector. The main parts of RDZ disconnectors made of ferrous metals have a resistant corrosion-resistant coating - hot or galvanic zinc.
