塑壳断路器也被称为装置式断路器，所有的零件都密封于塑料外壳中，辅助触点，欠电压脱扣器以及分励脱扣器等多采用模块化。由于结构非常紧凑，塑壳断路器基本无法检修。其多采德力西塑壳断路器用手动操作，大容量可选择电动分合。由于电子式过电流脱扣器的应用，塑壳断路器也可分为A类和B类两种，B类具有良好的三段保护特性，但由于价格因素，采用热磁式脱扣器的A类产品的市场占有率更高。 塑壳断路器是将触头、灭弧室、脱扣器和操作机构等都装在一个塑料外壳内，一般不考虑维修，适用于作支路的保护开关，过电流脱扣器有热磁式和电子式两种，一般热磁式塑壳断路器为非选择性断路器，仅有过载长延时及短路瞬时两种保护方式，电子式塑壳断路器有过载长延时、短路短延时、短路瞬时和接地故障四种保护功能。部分电子式塑壳断路器新推出的产品还带有区域选择性连锁功能。大多数塑壳断路器为手动操作，也有部分带电动机操作机构。

供应三菱塑壳断路器NF1000-SEW三菱机电英文概述：Tokyo, October 27, 2009 ? Mitsubishi Electric Corporation (TYO: 6503) announced today it has developeda 12.1-inch XGA color TFT-LCD module that is approximately 10% smaller in size with a reduced framewidth compared to its previous model. The new AA121XL01 offers super high brightness (up to 1,000cd/m2) and longer backlight life thanks towhite light emitting diodes (LED), and is inverter-less. Theseimprovements are expected to help reduce size and weight of portable data terminals and other displaymonitors for POS systems which incorporate the new model.The product will be available beginning February 1, 2010 through Mitsubishi Electric’s sales sitesin Japan, Europe, China, Korea, andTaiwan. Incorporating the technologies used in the AA121XL01, Mitsubishi Electric also intends to expandits lineup of smaller TFT-LCD modules to further meet customer needs. The cost per unit in Japan will be52,500 yen, including consumption tax.Background:In recent years, TFT-LCD modules have been widely used in a variety of applications and environments.Store or warehouse inventory management and factory processing management often relies on POS systemswith information display monitors as well as portable data terminals, which interpret digital pen movements.These applications in particular need TFT-LCD modules that are compact and maintain high brightness toensure high optical performance.Main Product Features:1) 10% smaller size and 20% less thickness helps reduce size and weight of portable data terminals andother display monitors for POS systemsWithout changing the 12.1-inch size of the active area, Mitsubishi Electric has reduced the module size from280.0mm (W) x 210.0mm (H) x 12.0mm (D) to 260.5mm (W) x 203.0mm (H) x 9.7mm (D), which is。TOKYO, December 5, 2017 ? Mitsubishi Electric Corporation (TOKYO: 6503) and the University of Tokyoannounced today that they believe they are the first to quantify the impacts of three electron-scatteringmechanisms for determining the resistance of silicon carbide (SiC) power semiconductor devices in powersemiconductor modules. They have found that resistance under the SiC interface can be reduced by two-thirdsby suppressing electron scattering by the charges, a discovery that is expected to help reduce energyconsumption in power equipment by lowering the resistance of SiC power semiconductors.Going forward, Mitsubishi Electric will continue refinindesignandspecifications of its SiC metal-oxidesemiconductorfield-effect transistor (SiC MOSFET) to further lower the resistance of SiC powersemiconductor devices. This research achievement was initially announced at TheInternational ElectronDevices Meeting (IEDM2017) in San Francisco, California on December 4 (PST).The impact that charges and atomic vibration have on electron scattering under the SiC interface was revealedto be dominant in Mitsubishi Electric’s analyses of fabricated devices. Electron scattering focusing on atomicvibration was measured using technology from the University of Tokyo. Although it has been recognized thatelectron scatting under the SiC interface is limited by three factors, namely, the roughness of the SiC interface,the charges under the SiC interface and the atomic vibration (see Fig. 1), the contribution of each factor hadbeen unclear. A planar-type SiC-MOSFET in which electrons conduct away from the SiC interface to aroundseveral nano meters was fabricated to confirm the impact of the charges. As a result, Mitsubishi Electric andthe University of Tokyo achieved an unprecedented confirmation that the roughness of the SiC interface haslittle effect while charges under the SiC interface and atomic vibration are dominant factors (see Fig. 2). 2/2Compared with a previous planar-type SiC-MOSFET device, resistance was reduced by two thirds owing tosuppression of electron scattering, which was achieved by making the electrons conduct away from the chargesunder the SiC interface. The previous planar-type device used for comparison has the same interface structureas that of the SiC-MOSFET fabricated by Mitsubishi Electric.For the test, Mitsubishi Electric handled the design, fabrication and analysis of the resistance-limiting factorsand the University of Tokyo handled the measurement of electron-scattering factors.BackgroundPower equipment used in home electronics, industrial machinery, trains, etc. requires a combination ofmaximized efficiency and minimized size. Mitsubishi Electric is accelerating use of SiC power semiconductordevices for power semiconductor modules, which are key components in power equipment. SiC power，semiconductor devices offer lower resistance than conventional Si power semiconductor devices, so to furtherlower their resistance it is important to understand the characteristics of the resistance under the SiC interfacecorrectly. Until now, however, it had been difficult to separately measure resistance-limiting。
“政府工作报告提到，要深入实施创新驱动发展战略，推动实体经济优化结构，不断提高质量、效益和竞争力。”3月6日，谈及今年的政府工作报告，全国政协委员、家蚕基因组生物学国家重点实验室主任夏庆友颇有感触。他认为，提升科技创新能力，可以从进一步调动科研院所、科技人员的积极性着手。“报告中提到，完善对基础研究和原创性研究的长期稳定支持机制。我认为非常有必要。”夏庆友说，科学研究大致可分为基础研究和应用研究两大类。基础研究一般没有专门的目的或特定目标，主要注重基本原理和理论性研究，是科研的基础，对一个国家而言非常重要。而应用研究则是主要针对某一特定目的或目标开展的研究，实用性很强，更多体现了科研院所的自主性。夏庆友说，十八大以来，国家先后出台多项政策，不断加强市场对科研资源配置的调控作用，让科研资源向重点领域、重点行业倾斜，起到了良好效果，也激发了科研院所和科研人员的积极性。报告中提出的“落实股权期权和分红等激励政策，落实科研经费和项目管理制度改革”等内容，更让人信心倍增。他认为，要进一步调动科研院所和科研人员的积极性，就应该让科研院所得名，让科研人员得利。“科研人员研究出成果、创造出价值，获得收益是应该的，而科研院所的存在和发展，也是建立在院所的声望和研究成果上的。”夏庆友说，科技创新为产业转型升级、经济社会发展提供动力，科研院所和科研人员功不可没，报告中提到这一点，表明了国家对提升科技创新能力的重视，让他十分期盼。仪器仪表
