Purpose of the development: Switchgear assembly City "Troika" (KRU / TEL-10-16 / 630-0111-V3) is intended for use in substations, which are an essential element of the ring schema urban cable networks 6 (10) kV.

Technical characteristic: Rated voltage 10 kV Rated current busbar A 400; 630 Rated current accession and 400; 630 Rated breaking current embedded switches, 16 kA The level of insulation in accordance with GOST 1516.1 normal Type of insulation combined Ingress protection from the service area IP40 Dimensions (width x depth x height), mm 68хh550х1700 The service life of 25 years before replacement

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: Rated current busbar up to 630 A Minimum installation work The most compact in its class switchgear It does not require setting up and maintenance

Description of the development:
()
Key Chain KRU series TEL fully protected solid insulating material, which, combined with air gaps between live circuits of different phases, provide the required degree of dielectric strength of internal insulation and eliminate the need for the use of sulfur hexafluoride. Overall dimensions of the control cabinet series TEL low for devices of this class - the width of the monoblock 3 connection on the front is 680 mm., Ie one connection takes 227 mm., Which significantly reduces the floor space RU 6 (10) kV and reduce the consumption of the basic building materials to create a transformer substation. Installation works are reduced to the control cabinet mounting / TEL-10-16 / 630-0111-V3 on the prepared base and connecting cable lines. As well as all the equipment brand TEL, complete switchgear KRU / TEL-10-16 / 630-0111-V3 keeps working during their lifetime without an adjustment, preventive or other maintenance. Urban Design "Troika" fully supports the expansion of both the number of connections, and functional capabilities. Since switchgear installed vacuum switches BB / TEL, designed to disable the full short-circuit currents up to 16 kA, it can easily be supplemented by modules of relay protection and automation, telemetry and remote control (system SCADA), an uninterruptible power supply secondary circuits and so forth. When This basic candy bar and switching devices remain unchanged, which gives substantial savings while increasing functionality.
