4 Description General information SION 3AE Lateral vacuum circuit breakers from kv to 4 kv SION vacuum circuit breakers control all switching operations in medium-voltage distribution systems and are suitable for installation in all established and new air-insulated mediumvoltage switchgear as well as for retrofitting existing switchgear. They are applicable for operation of e.g. overhead lines, cables, transformers, capacitors and motors. The optional installation accessories enable easy integration into switchgear panels. Our comprehensive range of lateral circuit breakers offers a wide selection of pole-center distances as well as various equipment options for voltage levels from kv to 4 kv. Compact dimensions and well-protected terminals enable simple integration into commonly used medium-voltage switchgear. High reliability and availability are a matter of course, as are 0,000 maintenance-free operating cycles. 3AE SION Lateral for kv 3AE3 SION Lateral for 4 kv HG-07_3AE.tif HG-07_3AE3.tif Thanks to a range of equipment options, SION vacuum circuit breakers can be precisely tailored to your requirements. 4 Catalog HG / 07

5 Siemens AG 07 Description Construction and mode of operation Switching medium 3AE Proven and fully developed for more than 40 years, vacuum switching technology is the principal arc-quenching element used in vacuum interrupters. Pole assemblies 3AE_V_0.ai The pole assemblies consist of vacuum interrupters and pole shells. The vacuum interrupters are air-insulated and freely accessible. The pole assemblies are fixed on the mechanism mounting plate and supported by means of the pole shell (). The vacuum interrupter () is mounted rigidly to the upper interrupter support. The lower part of the interrupter is guided into the lower interrupter support, allowing axial movement. The pole shell () absorbs external forces resulting from switching operations and the contact pressure. Front view Cover of low-voltage interface Operating mechanism The whole operating mechanism with motor (3), releases, indicators and actuating devices is mounted on the mechanism mounting plate (9). This compact design enables very fast operating times. 3 3 The circuit breaker operating mechanism is a stored-energy spring mechanism. The force is transmitted from the operating mechanism to the pole assemblies via operating levers. The closing spring () can be charged either electrically or manually, and latches in automatically when charging is complete. The closing spring () acts as a stored-energy mechanism kv Pole structure 3 Separating shell to the operating mechanism 4 Upper connection Vacuum interrupter Pole shell 7 Lower connection Insulator Trip-free mechanism AE_V_03_kV.ai For charging the closing spring (), the motor (3) operates in short-time duty. Therefore the voltage and power consumption might differ from the data of the motor rating plate. kv In this way, the stored-energy mechanism stores the OPEN CLOSE OPEN operating sequence that is required for an auto-reclosing operation on the system side. All stored-energy mechanisms perform the switching duties of synchronizing, rapid load transfer, and auto-reclosing. The circuit breakers have a trip-free mechanism. 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. However, the vacuum circuit breaker contacts are momentarily in the closed position AE_V_0.ai To close the breaker, the closing spring () can be unlatched either mechanically at the device (ON pushbutton), or electrically by remote control. The closing spring () charges the opening and/or contact-pressure springs as the breaker closes. The now discharged closing spring () will be charged again automatically by the motor (3).

6 Description Construction and mode of operation 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. The releases are designed for shorttime duty up to minute and are reset internally. The various types of releases available are described in detail below: Closing solenoid The closing solenoid unlatches the charged closing spring of the vacuum circuit breaker, closing it by electrical means. Shunt releases Shunt releases are used for automatic tripping of the circuit breaker by suitable protection relays and for deliberate tripping by electrical means. They are intended for connection to an external power supply (DC or AC voltage). Current-transformer-operated releases Current-transformer-operated releases consist of a stored energy mechanism, an unlatching mechanism and an electro magnet system. They are used when there is no external source of auxiliary power (e.g. a battery). Tripping is effected by means of a protection relay (e.g. overcurrent time protection) acting on the current-transformer-operated release. Undervoltage releases Undervoltage releases consist of a stored-energy mechanism, an unlatching mechanism and an electromagnet system which is permanently connected to the secondary or auxiliary voltage while the 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. A maximum of two releases can be equipped in accordance with page 3. The consumption data of the releases is listed on page. Closing spring charged indication The circuit breakers have a mechanically operated spring charged indicator. The charging status of the closing spring can also be queried electrically by means of an integrated position switch. Circuit breaker tripping signal During electrical opening, the NO contact S makes brief contact. This is often used to operate a hazard warning system which should respond to automatic tripping of the circuit breaker. In case of local control, the NO contact S does not close. For the corresponding circuit diagrams, refer to page 9. Interlocking Mechanical interlocking At the interface of the mechanical interlocking of the circuit breaker, sensors on the switchgear side can check the switch position and prevent the associated disconnector from being operated while the circuit breaker is closed. The system also prevents the circuit breaker from being closed while the associated disconnector is in the fault position. Electrical interlocking The auxiliary and signaling contacts which show the switch position of the circuit breaker electrically can be integrated into the switchgear interlocking concept in order to prevent impermissible switching sequences. Low-voltage interface The removable cover of the SION 3AE vacuum circuit breakers enables easy access to the low-voltage interface. All customer-side control and signaling options are concentrated here. Closing and anti-pumping In the standard version, the circuit breakers can be closed electrically via remote. In addition, they can be mechanically closed locally by direct unlatching of the closing spring. If constant electrical signals for CLOSE and OPEN commands are present at the circuit breaker at the same time, the circuit breaker will carry out an OPEN-CLOSE-OPEN or a CLOSE-OPEN operating sequence. A new CLOSE command is given only following a brief interruption of the closing signal. This prevents continuous closing and opening (= pumping ) operations. Catalog HG / 07

For enclosed switchgear, the data of the switchgear manufacturer applies. At ambient air temperatures below +40 C, higher operating currents can be carried (see diagram): Characteristics curve = Rated operating current 30 A Characteristics curve = Rated operating current 00 A Characteristics curve 3 = Rated operating current 0 A Dielectric strength Altitude correction factor Ka Ambient temperature Installation altitude H HG-7c_en.eps The dielectric strength of air insulation decreases with increasing altitude due to lower air density. According to IEC 7-, the rated lightning impulse voltage and the rated short-time AC withstand voltage values specified in the Chapter Technical data apply for an installation altitude of up to 000 m above sea level. For altitudes above 000 m, the insulation level must be corrected according to the diagram opposite. The characteristics curve shown applies to both rated withstand voltages. When selecting the devices, the following applies: U U 0 x K a U Rated withstand voltage under reference atmosphere U 0 Rated withstand voltage requested for the installation location K a Altitude correction factor according to the opposite diagram Example For a requested rated lightning impulse voltage of 7 kv at an altitude of 00 m, an insulation level of at least 90 kv under reference atmosphere is required: 90 kv 7 kv x.
