夏季的酷热使人难耐,空调、电风扇也都转了起来。因为使用这些电器而造成的火灾、触电事故每年都有发生,怎样既安全又科学地用电,是每个家庭必须注意的大事。首先,要考虑电能表和低压线路的承受能力。电能表所能承受的电功率近似于电压乘电流的值,民用电的电压是220伏,如家中安装2.5安的电能表,所能承受的功率便是550瓦,像600瓦的电饭煲则不能使用。如此推算,5安的电能表所能承受的电功率是1100瓦。其次,要考虑一个插座允许插接几件电器。如果所有电器的最大功率之和不超过插座的功率,一般是不会出问题的。用三对以上插孔的插座,而且要同时使用空调、电饭锅、电饭煲、电热水器等大功率电器时,应先算一算这些电器功率的总和。如超过了插座的限定功率,插座就会因电流太大而发热烧坏,这时应减少同时使用的电器数量,使功率总和保持在插座允许的范围之内。另外,安装的刀闸必须使用相应标准的保险丝(现在普遍用空气开关,保险丝基本已淘汰)。不得用其他金属丝替代,否则容易造成火灾,毁坏电器。如因家用电器着火引起火灾,必须先切断电源,然后再进行救火,以免触电伤人。 The summer heatmakesintolerable, air conditioning, electric fansturnup.Thefirecaused bytheuseofthese appliances,electric shockevery year, howsafe andscientificallyelectricity,each familymust pay attention totheevent.First of all,to considerthe affordabilityofenergy meterandlow voltage lines.Energy metercan withstandelectric powerissimilartothe valueofthevoltage multiplied bycurrent,public electricityvoltageis220 volts,such ashomeenergy meterinstallationto2.5,can withstand thepoweris550watts,likethe600-wattrice cookercan not be used.Such projections,5amppower metercan withstandelectric poweris1100watts.

Some safety measures in using electrcity
Nowadays,with the development of society and the improvement of people's life,an increasing
numbers of families have more and more domestic appliances ,which makes it of great
importance for people to make safe use of electrcity .
First of all,it's quite necessary to have the eitectrc circuit and thesocketsas well as switches
examined or checked regularly,which helps prevent any possible eitectrc problems at the
very root .
Secondly,it is strongly suggested that one should not turn on a lot of appliances at the
same time.In this case there is greater chance of electic problems or even disasters.
Thirdly,make sure that all the electricsockets should be kept out of the reach of babies and
little children.This can effectively get rid of the risks of babies and little children' getting
an electric shock.
In addition,while cooking or boiling water,one should keep an eye on the state of theelectric
cooker and kettle constantly and pull off the plugs or turn off the awitches in time.
Last but not least,it is considered wise to pull off all the plugs and put down all the switches
in order to cut off the electricty ,which is said to be helpful for preventing fires resulted from
thunderstorms or other potential dangers.
In conclusion,electricty is essential not only to instry and agriculture but also to our daily
life although it is also very dangerous for users.However,as long as we can make proper
and safe use of it, we can make it our best friend.
