压电陶瓷性能全参数解析汇报
即经过极化后的压电陶瓷具有两个介电常数ε11和ε33。
由于压电陶瓷存在压电效应，因此样品处于不同的机械条件下，其所测得的介电常数也不相同。在机械自由条件下，测得的介电常数称为自由介电常数，在εT表示，上角标T表示机械自由条件。在机械夹持条件下，测得的介电常数称为夹持介电常数，以εS表示，上角标S表示机械夹持条件。由于在机械自由条件下存在由形变而产生的附加电场，而在机械受夹条件下则没有这种效应，因而在两种条件下测得的介电常数数值是不同的。
上面两式弹性顺度常数S11和S12之比，称为迫松比，即
(1-9)
它表示横向相对收缩与纵向相对伸长之比。
同理，可以得到S13，S21，S22，其中，S22=S11，S12=S21。极化过的压电陶瓷，其独立的弹性顺度常数只有5个，即S11，S12，S13，S33和S44。
独立的弹性劲度常数也只有5个，即C11，C12，C13，C33和C44.
（1）介电常数
介电常数是反映材料的介电性质，或极化性质的，通常用ε来表示。不同用途的压电陶瓷元器件对压电陶瓷的介电常数要求不同。例如，压电陶瓷扬声器等音频元件要求陶瓷的介电常数要大，而高频压电陶瓷元器件则要求材料的介电常数要小。
介电常数ε与元件的电容C，电极面积A和电极间距离t之间的关系为
ε=C·t/A (1-1)
由于压电陶瓷存在压电效应，因此压电陶瓷样品在不同的电学条件下具有不同的弹性顺度常数。在外电路的电阻很小相当于短路，或电场强度E=0的条件下测得的称为短路弹性顺度常数，记作SE。在外电路的电阻很大相当于开路，或电位移D=0的条件下测得的称为开路弹性顺度常数，记作SD。由于压电陶瓷为各向异相性体，因此共有下列10个弹性顺度常数：

PA/V A SOLUTIONSVARIODYN D1Digital Public Address andVoice Alarm System2 | Voice Alarm is increasingly important in the safe management of buildings. A voice message informs occupants exactly what to do in an emergency and it is a long established fact that people respond more quickly and are more likely to take the correct action during an evacuation if voice messages are used instead of tone sounders.THE ROLE OF VOICE ALARM• Clear directions to people in the building• Live messages giving exactinstructions to people whoare not familiar with the surroundings • Customised pre-recordedmessages (available inmultiple languages)• Up to 20 minutes shorter response time to fire alarm• Serial Interface toHoneywell fire panels for EVAC guidance and time-controlled evacuation • High-end non-emergency features such asequalizing, automatic volume control and multi-channel announcements as well as backgroundmusic • Alarm cancellation and manual evacuation override controlBENEFITS | 3PUBLIC ADDRESS -MORE THAN VOICE ALARMVoice Alarm systems are more frequently used as public address and entertainment systems than only as automatic evacuation system inpublic buildings with a high number of visitors.• Paging and evacuation with zone-dependent messages • Integration with airport/train station managementsystems• Multiple channel/zone music broadcasting • Sport/concert hall and stadium sound systemintegration • Time-scheduled announcements• Touch screen operation panels• Operation from intuitive computer management systems • High quality background music for high class shopping experienceFEATURES PUBLIC ADDRESS PROVIDES ADDITIONALL Y:4 |Selecting, designing and commissioning a PA/VA system can be challenging. At Honeywell we have a team of experts that will help you build the most suitable system for your building.The first step is to decide exactly what type of PA/VA system you will need. This will largely depend on the size and functional complexity of your building.The following two types of systems are available that start from small ‘Compact Solution’ packages suitable for single storey buildings such as shops and offices and move up to a custommade ‘Modular System’ that will consist of a number of distributed systems linked together for large structures such as exhibition fairgrounds and airports.VOICE ALARMCOMPETENCE FOR YOU• Controlling and indicating equipment certified to EN 54-16 and EN 54-4• Complete range of EN 54-24 certified loudspeakers • Flexible systems that supports both simple and the most complex communication needs • High quality digital audio matrix• Intuitive touchscreen Graphical User Interface that manages the entire system • Phased evacuation scenarios • Situation, location & evacuation phasedependent voice messages • Exact guidance regarding evacuation routes• Freely configurableevacuation scenarios with logical dependencies • Dedicated Honeywelldesign and project supportSYSTEMS KEY FEATURES |5 LEISURE COMPLEXES SCHOOLS SMALL HOTELS OFFICESTHE COMPACT SOLUTION:COMPRIO D1An easy-to-install PA/VA system.Suitable for small to medium buildingswith up to 24 loudspeaker zones.APPLICATIONS• Leisure complexes• Supermarkets• Schools• Hotels• OfficesBENEFITS• Amplifier with build-in PSU available• ‘Off the Shelf’ Package• Installation within two hours• Only 8 HU rack space incl. amplifier,charger and batteries• Ensured compliance to ENstandards• Complete solution for up to 24zones• max. 2000 W output powerexpandable with additional DOM/AMPs6 | Our PA/VA systems can be distributed and networked together to deliver the most comprehensive and powerful solution for a wide range of applications.

The endangered areas are then selected automatically and informed via the PA/VA system, while at the same time the fire alarm control panel activates fire protection systems, for example, fire doors, air-conditioning and ventilating systems, elevator controls or smoke dampers.The combination of voice alarm and fire alarm technology not only offers functional advantages, there are economical advantages as well: PA/VA reduces the total EVAC time significantly, a PA/VA system is not much more expensive than standard sounders, while it adds valuable support by increasing productivity of building occupants.8 | | 9VARIODYN D1 AND COMPRIO PA/VA SYSTEM DIAGRAM Thanks to its modular construction and the varioussystem components, the VARIODYN D1 system can easily DCS Digital Call Station DSCF DSC for Firefighter Fire Alarm Control PanelInterfaceDOMAMP PSUDCSF 1/12Configuration via LaptopCD playerETCSDCS PlusCentral Operating Terminal(PAMMI, WINMAG, Honeywell EBI etc)Loop Isolator ModuleAdvanced,Automatic Volume Control10 | WINMAGPLUSONE MANAGEMENT SYSTEM FOR ALLPERFORMANCE FEATURES OF THE VARIODYN D1 INTERFACE WINMAGPLUS DRIVER• System configuration readout of a VARIODYN D1 network to take it over via import files to WINMAGplus application.• Fault and status indication of the VARIODYN D1 system components: • DOM, SCU, DAL bus devices like DCS and • UIM, Amplifiers (each channel)• Audio and control contact inputs and outputsThe WINMAGplus hazard management system lets you create a scalable software solution with superb levels of integration with different sub-systems.In case of Voice Alarm system, VARIODYN D1 is connected via Ethernet/RJ45 to the same network as the WINMAGplus server.

Simplified, prescriptive method, requiring loudspeakers mounted every 6 meters or less.2. Detailed method, requiring in practice acoustics simulations as VA system design base regarding spacing, location, type selection, audio equalizing and proper orientation of loudspeakers.Acoustic simulations are paramount for a proper PA/VA system design in complex, tough and large areas. EN 50489 and CEN/TS 54-32 require minimum intelligibility level from installed VA systems. Installing and planning VA systems bears a risk of failure during intelligibily measurements in the handover phase. Toprevent such critical situations and underbudgeting of VA systems acoustic simulations are the only guarantee. |13EXAMPLE OF THE ACOUSTIC SIMULATION OF AN AUDITORIUM Acoustic simulation software provides to precisely and reliably assess sound pressure level (dB) and intelligibility level (STI/CIS). The software calculates the simulatedroom as a space map in 3D, enabling the user to verify the selected type, location and setting of loudspeakers.Voice Alarm system design for acoustically challenging areas must be based on professional, quality simulations,prepared by experienced acoustic experts.Our Technical Support Team provides expertise, experience, tools and wide portfolio of certified VA loudspeakers to assure our partners and system designers that Variodyn D1 system designs will pass acceptance tests.14 | VARIODYN D1 PRODUCT FAMIL YAll of the components of the VARIODYN D1 product family are compatible, interchangeable and optimally adapted to the customers growing needs. As varied as the requirements may be, all of the components are modular designed andcan be combined with each other quick and easy.ComprioComprio is a voice alarm system optimised for small and medium-size facilities such as schools,hotels, leisure centres and offices. It's characterised by its compact design, wide performance range and its flexibility.Digital Output Module (DOM)The Digital Output Module (DOM) is the heart of the Honeywell Voice Alarm and Public Address system.

压电陶瓷变压器
压电变压器直流高压电源设计摘要压电陶瓷变压器是一种新型的压电换能器件，具有尺寸小，结构简单，不可燃，耐辐射，高可靠等优点。
压电变压器在电视显像管、雷达显示管、静电复印机、静电除尘、小功率激光管、离子发生器、高压极化等设备中得到广泛的应用。
本课题是研究压电变压器设计出10kV的直流高压电源。
当在压电陶瓷变压器输入端（驱动部份）加入交变电压时，通过逆压电效应，瓷片产生沿长度方向的伸缩振动，将输入电能转变为机械能；而发电部分则通过正压电效应将机械能转换为电能从而输出电压因瓷片的长度远大于厚度，故输出端阻抗远大于输入端阻抗，输出端电压远大于输入端电压．一般输入几伏到几十伏的交变电压，可以获得几千伏以上的高压输出．关键词：压电陶瓷变压器直流高压阻抗Design of Piezoelectric Transformer DChigh voltage power supply ABSTRACTPiezoelectric ceramic transformer is a new type of piezoelectric transducer device, the size is small, simple structure, non-combustible, resistance to radiation, high reliability.
