Description General 3AH47 Vacuum Circuit-Breakers 3AH47 circuit-breaker The Special for railway electrification applications at 17.5 kv and 27.5 kv 1 The electrical power supply for railway systems requires circuit-breakers with special features. Not only are there single-pole circuit-breakers in normal operation, but also the high requirements regarding operational reliability and number of operating cycles reach far beyond the standards of other applications. 3AH47 impressive with one or two poles R-HG11-206.tif R-HG11-207.tif The vacuum circuit-breaker series 3AH47 offers both for 16 2 /3 Hz at a rated voltage of 17.5 kv and for 50/60 Hz at a rated voltage of 27.5 kv an impressive product range with rated normal currents up to 2500 A and rated shortcircuit breaking currents from 25 ka to 31.5 ka, and even up to 50 ka at 17.5 kv. 3AH47 vacuum circuit-breakers control up to 60,000 operating cycles. Minimum maintenance work, such as greasing of operating mechanisms after 10,000 operating cycles and replacement of vacuum interrupters after 30,000 operating cycles, preserves the reliability of these circuit-breakers throughout their entire service life. 6 Siemens HG 11.52 2010
Description Construction and mode of operation The 3AH47 vacuum circuit-breaker consists of the pole assembly (1) and the operating mechanism box (2). The pole assembly is fixed to the operating mechanism box via post insulators (3). The switching movement is transferred by means of operating rods (4) and levers. Switching medium The vacuum switching technology, proven and fully developed for more than 30 years, serves as arc-quenching principle by using vacuum interrupters. HG11-2607 eps 2 3 4 1 1 Pole assembly 2 Operating mechanism box 3 Post insulator 4 Operating rod 1 Pole assembly A pole assembly consists of the vacuum interrupter (6) and the interrupter supports. The vacuum interrupter is airinsulated and freely accessible. This makes it possible to clean the insulating parts easily in adverse ambient conditions. The vacuum interrupter is mounted rigidly to the upper interrupter support (5). The lower part of the interrupter is guided in the lower interrupter support (7), allowing axial movement. The braces absorb the external forces resulting from switching operations and the contact pressure. Operating mechanism box The whole operating mechanism with releases, auxiliary switches, indicators and actuating devices is accommodated in the operating mechanism box. The extent of the secondary equipment depends on the case of application and offers a multiple variety of options in order to meet almost every requirement. Operating mechanism The operating mechanism is a stored-energy mechanism. The closing spring is charged either electrically or manually. It latches tight at the end of the charging process and serves as an energy store. The force is transmitted from the operating mechanism to the pole assembly via operating rods. To close the breaker, the closing spring can be unlatched either mechanically by means of the local ON pushbutton or electrically by remote control. The closing spring charges the opening or contact pressure springs as the breaker closes. The now discharged closing spring will be charged again automatically by the mechanism motor or manually. Then the operating sequence OPEN-CLOSE-OPEN is stored in the springs. The charging state of the closing spring can be checked electrically by means of a position switch.

In the event of an opening command being given after a closing operation has been initiated, the moving contacts return to the open position and remain there even if the closing command is sustained. This means that the contacts of the vacuum circuit-breakers are momentarily in the closed position, which is permissible according to IEC 62271-100.

Description Construction and mode of operation, standards 3AH47 Vacuum Circuit-Breakers 1 Releases A release is a device which transfers electrical commands from an external source, such as a control room, to the latching mechanism of the vacuum circuit-breaker so that it can be opened or closed. How many releases are used and how they are combined is defined when the secondary equipment is selected. The closing solenoid unlatches the charged closing spring of the vacuum circuit-breaker, closing it by electrical means. Shunt releases are used for tripping the circuit-breakers via protection relay and for manual tripping via electrical operation. For this purpose they are operated with an auxiliary voltage (AC or DC) supplied by the protection relay or the control room. Instantaneous releases are used for switching duties with extremely short breaking times, especially for applications in 16 2 /3 Hz systems, in order to keep the arcing time short. For operation of the instantaneous release, a capacitor tripping unit is required additionally. Undervoltage releases comprise a stored-energy mechanism, an unlatching mechanism and an electromagnetic system, which is permanently connected to voltage while the vacuum circuit-breaker is closed. If the voltage falls below a predetermined value, unlatching of the release is enabled and the circuit-breaker is opened via the stored-energy mechanism. Closing In the standard version, the 3AH47 vacuum circuit-breakers can be remote-closed electrically. They can also be closed locally by mechanical unlatching of the closing spring via pushbutton. Instead of this manual mechanical closing, manual electrical closing is also available. In this version, the closing circuit of the circuit-breaker is controlled electrically by a pushbutton instead of the mechanical button. In this way, switchgear-related interlocks can also be considered for local operation in order to prevent involuntary closing. If constant CLOSE and OPEN commands are present at the vacuum circuit-breaker at the same time, the vacuum circuit-breaker will return to the open position after closing. It remains in this position until a new CLOSE command is given. In this manner, continuous closing and opening (= pumping ) is prevented. Circuit-breaker tripping signal The NO contact makes brief contact while the vacuum circuit-breaker is opening, and this is often used to operate a hazard-warning system which, however, is only allowed to respond to automatic tripping of the vacuum circuitbreaker. Therefore, the signal from the NO contact must be interrupted when the circuit-breaker is being opened intentionally. This is accomplished under local control with the cut-out switch that is connected in series with the NO contact. Interlocking Mechanical interlocking The switch position of the circuit-breaker is checked from the switchgear side, and its closing is blocked if the associated disconnector is in faulty position. On the other hand, disconnector operation is prevented while the circuit-breaker is closed. Accordingly, the mechanical interlocking can also be used to interlock against circuit-breaker trucks or withdrawable parts. Electrical interlocking The vacuum circuit-breakers can be integrated in electromagnetic feeder or switchgear interlocks. In case of electrical interlocking, the disconnector or its operating mechanism is equipped with a magnetic lock-out mechanism. This mechanism is controlled by an auxiliary contact of the circuit-breaker, so that the disconnector can only be operated when the circuit-breaker is open. On the other hand, the circuit-breaker is also controlled by the disconnector or its operating mechanism, so that it can only be closed when the disconnector is in an end position. For this purpose, manual electrical closing must be provided in the circuit-breaker operating mechanism (see Closing ). Standards 3AH47 vacuum circuit-breakers conform to the following standards: EN 50152-1 IEC 62271-100 (former IEC 60056) IEC 62271-1 (former IEC 60694) BS 5311 VDE 0671 (former VDE 0670) All 3AH47 vacuum circuit-breakers fulfill the endurance classes E2 and C2 according to IEC 62271-100, and surpass the endurance class M2 six times (60,000 operating cycles). 8 Siemens HG 11.52 2010
Description Ambient conditions, current carrying capacity and dielectric strength Ambient conditions The vacuum circuit-breakers are designed for the normal operating conditions defined in IEC 62271-100. Condensation can occasionally occur under the ambient conditions shown opposite. 3AH47 vacuum circuitbreakers are suitable for use in the following climatic classes according to IEC 60721, Part 3-3: Climatic ambient conditions: Class 3K4 1) Biological ambient conditions: Class 3B1 Mechanical ambient conditions: Class 3M2 Chemically-active substances: Class 3C2 2) Mechanically-active substances: Class 3S2 3) 1) Low temperature limit: 5 C 2) Without icing and wind-driven precipitation 3) Restriction: Clean insulation parts 40 C -5 C max. 95% per day max. 90% per month HG11-2515a_en eps 1 Current carrying capacity The rated normal currents specified in the opposite diagram have been defined according to IEC 62271-100 for an ambient air temperature of + 40 C and apply to open switchgear. For enclosed switchgear the data of the switchgear manufacturer applies. At ambient air temperatures below + 40 C, higher normal currents can be carried (see diagram): Characteristics curve 1 = Rated normal current 1250 A Characteristics curve 2 = Rated normal current 2000 A Characteristics curve 3 = Rated normal current 2500 A Rated normal current 3400 A 3000 2600 2200 1800 3 2 Dielectric strength The dielectric strength of air insulation decreases with increasing altitude due to low air density. According to IEC 62271-1, the values of the rated lightning impulse withstand voltage and the rated short-duration powerfrequency withstand voltage specified in the chapter Technical Data apply to a site altitude of 1000 m above sea level.
