极限挑战第三季

工业和信息化部拟加强电动自行车用充电器安全技术管理_我的网站

一 |     Ottawa, Oct 20 (UNI) Hurricane Fiona is estimated to have caused 660 million Canadian dollars (about 528 million US dollars) in insured damage in Canada, the Insurance Bureau of Canada said.



Fiona is the most costly extreme weather event ever recorded in Atlantic Canada, and the tenth largest in the country in terms of insured damages, the bureau said in a press release, quoting the "record-breaking" initial estimates from Catastrophe Indices and Quantification Inc.



Many affected residents were located in high-risk flood areas and floodplains where residential flood insurance coverage is not available. As a result, the overwhelming majority of costs for this disaster will be borne by government, according to the release.



"As we begin to see the extent of damages caused by Hurricane Fiona, it is clear that much more needs to be done to enhance our resilience to extreme weather events and build a culture of preparedness moving forward," said Amanda Dean, vice-president, Atlantic, Insurance Bureau of Canada.



The long-lived and powerful storm first made landfall in Atlantic Canada on Saturday, September 24. With maximum wind gusts exceeding 100 km/h in Atlantic Canada and Eastern Quebec, Fiona resulted in tragic loss of life as well as violent winds, torrential rainfall, large waves, storm surge, downed trees and widespread power outages, the release said.



Insurance claims from severe weather have more than quadrupled across Canada since 2008. The new normal for insured catastrophic damages in the country has reached 2 billion Canadian dollars (about 1.6 billion US dollars) annually.

UNI/XINHUA PRT。    工业和信息化部近日公开征集对《电动自行车用充电器安全技术要求》强制性国家标准第1号修改单（征求意见稿）的意见。征求意见稿在“防触电保护类别”中，增加了电动自行车用充电器不得设计、制造及使用车载形式。　　中国电子技术标准化研究院安全技术研究中心副主任何鹏林表示，增设对电动自行车车载形式充电器的技术管理要求，主要考虑到其可能带来的安全隐患。　　什么是车载形式充电器？据悉，车载形式充电器一般是指出厂时直接集成在电动自行车内部、不借助工具通常无法从车体上分离的充电器。这类充电器由于直接为电动自行车引入220V的交流电压，易造成漏电、触电等问题，在使用过程中不利于热量散发，存在较大风险隐患。　　何鹏林介绍，与车载形式充电器相对应的是外置充电器，形态可与电动自行车本体分离。目前，电动自行车销售时附赠的充电器以及消费者自行购买的充电器，绝大多数为外置形式。

二 | 外置充电器不在此次提出的“电动自行车用充电器不得设计、制造及使用车载形式”范围内。

三 | 值得一提的是，市面上常见的、为了防止丢失而被消费者临时存放在车体内部（如储物箱中）的外置充电器不会被视为车载形式充电器。

四 | 　　此次征求意见稿中，标准的修改还包括增加了耐高温永久性标识等内容，旨在进一步提高电动自行车用充电器的安全性、可追溯性，推动电动自行车行业健康发展。
