Elephants are the biggest animals on the land.They are big and srong.They have big ears and trunks.They can walk quietly and help people move heavy things. They are very friendly,kind and always live together.But the number of elephants reduces.People kill elephants for their ivories.We must take action to protect them or else they will extinct from the world.
尊敬的居民用电客户朋友们大家好!
近年来,随着人民生活水平的不断提高,现代家庭安装使用的电器设备也越来越多,如空调、微波炉、电磁灶等,使得家庭中用电的总功率大幅度上升。我县老旧居民楼居室的电源导线一般设计为6至l0A,总负荷1.5至2 kW,当用电总功率超过2.5 kW时就存在电线短路起火、电表烧毁的可能。最常见的莫过于超负荷、电线短路、接触不良等原因引起的电气火灾。那么,老旧居民住宅中如何安全用电,将电气火灾拒之于门外呢?电力管理者认为关键要加强防范。家庭配电箱的布臵及负荷的要求:在老旧居民住宅中,通常家庭中配电箱上都装有熔断器,在熔断器中又安装有保险丝,当通过保险丝的电流超过允许的安全数值时它就会熔断,因此不能将配电箱安放在可燃物品的上方,防止炽热的熔珠落下后将物品引燃。保险丝的选择要根据家庭中电器总功率来确定,选择过大的保险丝起不到保险作用;选择过小的保险丝则会经常被烧断。保险丝的熔断电流通常为额定电流的1.5一2.0倍,若家庭中电器总功率不超过l.lkW的,选择5A的保险丝就可以了;当通过它的电流超过7A时,保险丝就会自动熔断,达到保护的目的。如果选用的保险丝符合规格但又经常熔断,则说明电源线路或用电器有间题,应及时地查找原因以清除隐患,切不可随意更换粗保险丝或干脆用铝、铜甚至铁丝代替,使熔断器起不到保护作用。如果家中电线的安全用电量在2.2 kW ( 10A ,晚上同时
使用电灯、电视、空调等用电器用电量达到2.1 kW左右,此时再使用一个功率为0.5 kW的电熨斗,电路就超负荷了,要是再使用微波炉就更加危险了。在超负荷情况下使用的电线绝缘层老化速度会加快,如果线芯发出的`热量使绝缘层的温度超过250,电线就会着火,因此对电线的选择要考虑用电电流,不能超负荷用电。有条件的家庭还可安装漏电保护器,当有电流泄漏(包括人身触电等事故发生时,它可以及时动作并切断电源,这样就更增加了安全系数。
电线的选择:目前很多家庭使用的电源线路大多还是十几年前或更早建房时铺设的,与现代家庭电器要求不相适应。在20xx年前所建的居民住宅楼,居室内所配导线全是1.5mm2的双铝芯护套线。线路经过若干年的使用后电线表面的绝缘层逐渐松散、老化,会造成轻微漏电,严重时会造成短路起火,酿成火灾烧毁设施。
目前,县城区内的不少老旧住宅楼房的单元保护开关和个人家庭使用的保护开关可靠性差、质量不符合要求或是无铭牌的低劣产品,当出现用电短路、过负荷、接触不良、漏电等情况时,不能有效起到保护作用,随时都有发生火灾的危险。随着民用电器的快速普及,当初设计的负荷己不能满足供电要求,以臵于在特殊原因导致居民楼房电气线路载流量不够,导致线路温度过高,会使导线的绝缘层老化,导线的绝缘层老化以后,就有发生火灾的危险。
鉴于上述原因,电力公司温馨提示老旧住宅楼的用电客户、朋友们:
1.避免两种或两种以上大功率用电器同时使用;
2.避免多种家电在同一个多用插座上同时开启使用; 3.合理使用空调、多功能电扇。
4.家用电脑、饮水机、电视机、热水器等耗电设备不要同时要开启使用。
4.积极推广使用节能灯具,提倡绿色照明。
Elephants are the biggest wild animals in land, in the world. But now, they are also in danger. Let me tell something to you about them.
Elephants are big and strong and they are grey. They have long trunks and tusks, so they look a little dangerous. But in fact, they’re friendly towards each other and hardly hunt people.
Elephants have ears like fans, they make them look bigger and bigger.
They live in a group together for many years, they’re a big family. They also have good hearing and good sense of smell. Elephants can do lots of things if people train them. For example, they can carry heavy things, can do as a vehicle, ext.
Badly, it’s difficult for elephants to survive in the world usually because of people. If people sell tusks, they will make lots of money.
So, many people kill elephants for their tusks. Living areas are also an important reason of the die out of elephants.
Animals are our friends, we should protect them, or the number of wild animals will getting smaller and smaller.
I like elephants. They are very gentle and they can walk quietly and help people move heavy things.
Elephants are the biggest animals on the land.They are big and strong.They have big ears and trunks. It weights some ninety kilograms and is about one metre high when born. When it is 12 years old, it is over three meters high and does not grow any more. Elephants are usually grey in color. They usually live in groups and care for each other.
We should protect elephants . They are the friends of ours.
Elephant is the largest animal on land today. It weights some ninety kilograms and is about one metre high when born. When it is 12 years old, it studs over three meters and does not grow any more. Elephant is usually grey in color, having a long trunk with large ivory tusks protruding from each side of its mouth. Usually moving in groups and caring for each other, Elephant is know to be a very and gentle creamre. For many years people have used the strength of these poweful animals to move trees and heavy logs. Elephant has been and is a vital tool for people to do many things that would normally be imposs-ible. Elephant is and will continue to be one of the greatest creatures man has ever come into contact with. Its size. beauty, and power willforever be useful to man.
我的童年是多姿多彩的,有喜,有怒,有哀有乐,那些事情有时很可笑,有时又很无奈。
我的小时候,什么都不知道,主要是哭,学会走路的时候乱跑,到早教班也是玩儿,好不容易学会了一个“大"字,还是我哥教会我的。我小时候还经常逃课,逃午睡,躲到男厕所里不出来,由于大部分老师都是女性,所以我们总能逃过午睡。现在想想,我都不知道那些时间我是怎么耗过去的。
有次,妈妈因为当时的我还够不着马桶,就给我买了个尿盆回来,绿色的还泛着点黄色,刚拿回来的时候我还不知道这是干什么用的,好奇的这边瞧瞧那边看看,端详了一阵后,举起了尿盆,妈妈不知道我又在搞什么怪也只是看着我不为所动。只见我”咣“的一下把尿盆我的头上,当帽子戴了!我那时候头还很小,如果按我现在的头围把尿盆往头上扣,应该像个西瓜太郎,但像我原来那么小的头,尿盆往上一放把脸也给盖住了,成了四不像,妈妈看见了”扑哧“笑出了声,看不下去了,过来纠正了我,我乖乖的往里面撒尿,尿完之后把尿到了又扣在了头上,一点儿也不长记性。
我童年的事,常常有一些滑稽的举动,但是在家长看来它是可爱的,在现在的我看来是可笑的,我一些早教班的老师对我的逃课现象当然是可气的。
小时候的我就是这样:可爱,可笑又可气。
每当看到那部剃须刀,七彩的童年生活犹如放电影般呈现在了我的脑海中,久久挥之不去。
那年我才四岁,有一天我去姥爷家,看着家中柜上面各种各样的摆设品,强烈的好奇心驱使我不住地摸摸这儿,玩玩那儿。忽然老爷手中的一个黑盒子”吸引了我的注意力,他长得并不好看。却能发出嗡嗡的声音。姥爷拿着它在嘴边蹭来蹭去,一副悠闲自得的样子,那感觉简直像腾云驾雾的活神仙。而站在一旁的我早就看得心痒痒了,眼睛直直地盯着黑盒子,恨不得马上就体验一下那感觉。好不容易等到姥爷出去,我立刻一个箭步冲上去。拿起黑盒子”,随手按了一个按钮,那玩意儿立刻不停的震动起来,犹如蜜蜂采蜜般嗡嗡地叫起来,真好听。我尝试着慢慢用它在脸上蹭来蹭去,啊!那感觉仿佛把整个脸都埋进了棉花里,皮肤都跟着不停颤动,舒服极了。这时姥爷回来了,他神情怪异地盯着我看,忽然缓缓地问:你的眉毛哪儿去了?”我闻声大惊,急忙拿起镜子一瞧,嘿,果真我的眉毛竟不翼而飞啦!我吓得哇哇大哭起来,姥爷却忍不住哈哈大笑。这时我又瞅见了镜中那个狼狈不堪的我,又不禁破涕而笑。
冰心曾说过,童年是梦中的真,是真中的梦,是回忆时含泪的微笑,这句话是多么贴切啊。
