The developed 0 . 2s multifunctional electric energy meter considering harmonics has passed the patterns tests by electric measuring research school of china electric 本文研制的考慮諧波的0 . 2s級多功能電能表通過了中國電力科學(xué)研究院電測量研究所的型式試驗。
In the hardware level , the system acquires motor armature current by wb current sensor and pci - 1202 card . hence wb current sensor , peripheral driving circuits , pc - 1202 card and its interfaces are respectively discussed in detail in the paper . as a perfect example of the new pattern testing system previously mentioned , the system has distinct advantages because it fully exploits abundant resources and rapid speed of pcs 論文中介紹了一種無轉(zhuǎn)矩轉(zhuǎn)速傳感器直流電機快速測試系統(tǒng),在硬件上,本系統(tǒng)由wb電流傳感器與pci - 1202數(shù)據(jù)采集卡共同完成電樞電流數(shù)據(jù)采集功能,論文詳細(xì)討論了wb電流傳感器,外圍驅(qū)動電路, pci - 1202數(shù)據(jù)采集卡及其與pc機的接口及其編程等等與軟硬件有關(guān)的問題。
In this paper , it also analyses the disadvantages of methods in present pavement specification . by means of parallel field test experimentation , and gives the correlativities between test methods of specification and new pattern test methods , such as road surface profiler , ground penetrate rada test system , friction test vehicle , falling weight deflectometer . based on these correlativities , their test and quality control standards are formed 本文還分析了路面現(xiàn)行檢測方法存在的問題,通過現(xiàn)場不同方法的對比檢測,建立了激光平整度測試車、探地雷達(dá)測試系統(tǒng)、摩擦系數(shù)測試車和落錘式彎沉儀( fwd )等新型檢測方法和規(guī)范測試方法間的相關(guān)關(guān)系,從而提出新型檢測的質(zhì)量控制標(biāo)準(zhǔn)。
This company , beginning fairly early to develop and manufacture themal protector , ptc started and current relay , has accumulated certain rechnical capability and rich manufacture experience . it boasts advanced manufacture and inspection equipment and device , such as precision punch , precision dryer , energy - reserve welding machine , ampere time characteristics detector , temperature characteristics detector , life test platform and key equipment for part - processing , finished product assembly , finished product inspection and pattern test . to guarantee product quality and expand manufacture capability , a production line has been designed and installed . with the aim of absorbing advanced technology and creating famous brand ted , we are planning to introduce equipment , material and know - how from abroad to satisfy users demand with quality product and excellent service 公司較早開始研制熱保護器電流繼電器及ptc啟動器,對生產(chǎn)熱保護器電流繼電器具備了一定的技術(shù)力量和豐富的生產(chǎn)經(jīng)驗,現(xiàn)有熱保護器及電流繼電器的生產(chǎn)和檢測設(shè)備:精密沖床精密干燥箱儲能焊機安培時間特性檢測儀溫度特性檢測儀壽命檢測臺零件加工成品組裝成品檢測和型式實驗的關(guān)鍵設(shè)備。并設(shè)計制造安裝了生產(chǎn)線,保證了產(chǎn)品質(zhì)量,擴大了生產(chǎn)能力。為集天下之技術(shù),創(chuàng)tde名牌,準(zhǔn)備從國外引進(jìn)的設(shè)備材料和技術(shù)。
