Heinl oth hanz-Stra ße 21 TGA-Z fgh-ma.com M-02-9 0 The Centre Break Disconnectors from Siemens Our centre break disconnector family is available for rated voltages from 72.5 kV up to 420 kV. The centre break disconnector is the most frequently used disconnector type worldwide. The base frame (4) carries the compact operating mechanism (5) and two rotating base mounted supporting insulators (2). In the closed position, the current flows via the current path arms (1), which are fixed to the insulators. The disconnector opens in the centre, thus providing an insulating distance. Each rotating unit (3) comprises two high quality sealed ball-bearings and is designed for high mechanical loads, therefore providing a maintenance free service life. These qualities result in low service and investment costs which provide our customers with competitive advantages worldwide. 1 2 3 4 5 1 Current path arms 2 Supporting insulators 3 Rotating unit 4 Base frame 5 Compact operating mechanism 3 The Contact System The main contact system has been adopted from the well established range of Ruhrtal high-voltage disconnector products. This system consists of block contacts and spread contact fingers and assures a steady contact force even after decades of operation. The current flows in the contact head from the terminal (7) to the current path tube (6) through highly-flexible copper leads (8). 6 7 8 The most significant features are: Self-resilient contact fingers, no further spring elements necessary to generate the contact force Factory-set contact forces, no re-adjustments required during service life Ice layers up to 20 mm can be broken without difficulties Silver-plated contact surface providing highest conductivity without regular grease lubrication Maintenance-free contact system up to 25 years By using the well-established blockfinger contact system, we provide our customers with very practical advantages: smooth operation, exemplary availability and optimum security. 4 The Earthing Switch The use of earthing switches ensures absolute safety by grounding and discharging all high-voltage components in a circuit or switchgear. Suitable built-on earthing switches are available for the complete range of our centre break disconnector types from 72.5 up to 420 kV. Three-pole centre break disconnector with earthing switch in inboard design 5 Motor Operating Mechanism 2 1 3 The motor operating mechanism includes all components required for operating the disconnector and consists of three main subassemblies: 1 Corrosion-resistant housing (protection degree IP 55) 2 Gear unit with motor 3 Electrical equipment with auxiliary switch The motor operating mechanism can also be operated manually by a hand crank which can be inserted inside the cubicle. The insertion of the hand crank automatically isolates the motor circuit for safety purposes. Heaters are provided to prevent condensation. 6 Technical Data High-Voltage Centre Break Disconnectors Rated voltage Type 3DN1 [kV] 72.5 123 145 245 300 362 420 Rated power frequency withstand voltage common value [kV] 140 230 275 460 395 450 520 across isolating distance [kV] 160 265 315 530 435 520 610 1050 1175 1425 Rated lightning impulse withstand voltage common value [kV] 325 550 650 1050 across isolating distance [kV] 375 630 750 1200 1050 + 170 1175 + 205 1425 + 240 Rated normal current Rated short-time withstand current (1 s - 3 s) Temperature range 1250/1600/2000/2500/3150 A up to 50 kA -50 ... +50 °C Rated frequency 50/60 Hz Control voltage 110/125/220/250 VDC Motor voltage 110/125/220/250 VDC or 230 VAC, 50 Hz/ 60 Hz Values in accordance with IEC, other values on request 7 For further Information Please fax this page to the following number: Fax +49 30/386-25867 Name/Company or send us an e-mail: [email protected] Street Postal code/City/Country Phone/Fax E-mail Please send me more information on the following topics: Ruhrtal - Disconnectors and Earthing Switches High-voltage circuit-breakers: Type 3AP1/2, 72.5 kV to 550 kV High-voltage circuit-breakers for outdoor installation Live-tank and dead-tank high-voltage circuit-breakers technology High-voltage compact switchgear 3AP1 DTC for 145 kV and 245 kV Eliminate stress: Controlled switching of high-voltage circuit-breakers SF6 in power engineering - acting responsibly Further copies of this brochure Published by and copyright © 2009 Siemens AG Siemens AG Energy Sector Energy Sector Power Transmission Division Freyeslebenstrasse 1 High Voltage Products 91058 Erlangen, Germany Nonnendammallee 104 13629 Berlin, Germany www.siemens.com/energy For more Information please contact our www.hv-circuit-breaker.com Customer Support Center.
