目前手里一套房子正在装修过程中,感觉装修真的好贵啊,全部弄齐每平米必须超过2200,荷包在滴血中。能省的地方那当然都得省,装修材料,我们尽量买便宜的,当然,还得货真质优。

装修公司进场时经理就说原来的电箱小了,让买个20位以上的,到选的时候,想想干脆大点,空着也好过放不下空开嘛,于是整了个24位的。不喜欢双排,还是买的单排。德力西86块,入手渠道是淘宝,后面买东西发现拼多多的明显都要便宜一些,所以后面基本都是把拼多多当采购基地了。

先看看大电箱。

到电线穿完,电工师傅给写的空开单子是1个63A两位、1个32A、6个20A和3个32A漏保。了解下价格,施耐德西门子罗格朗这些都挺贵的,就选国产吧,空开只要满足国标就没问题。看看现在住的房子里用的空开,居然不知名的牌子,还稳稳的用了十年以上。想想正泰也算是大名鼎鼎了,就它吧。

确定了品牌,去京东淘宝拼多多逛了一圈,明显拼多多更便宜,正泰旗舰店出的也不用担心假货。当然,还要想办法拿到更优惠的价格。

五折平台券那个真的很香。

拼多多超级省里面天天折扣,连买七天,最便宜的券是五折减50,买了两次。不知道现在我的怎么没有了,可能是被屏蔽了吧。DZ47和漏保入了一部分后,发现正泰还有个泰极系列,质量可能不一定更好,颜色看起来高端些。问了客服说可以混用,于是又拿五折券买了四个20A的空开,这个时候5折的最高优惠金额已经只有20了。

空开漏保都到了,看看样子吧。

漏保贵一些,有正泰的包装盒。

泰极系列也是随便堆在盒里里的,毕竟这玩意小磕碰也不会坏。

不愧是专业级,多了层塑封。仔细看了下,白色蓝色都是GB/T10963.1,白色款开合有个小窗口显示状态,蓝色款没有,开关上喷了off表示关闭状态。

价格是真的优惠,估计一百左右全部搞定。劲省五百,本来想玩个谐音梗,没想到违规,只能删了发布。

蔡绍路28832005年前630a空开触头是什么材料 -
洪冠柏18430327070 ______ 这么大的空开,触点一般都是合金银,含银比重决定品质高低.

蔡绍路2883大型电器开关里的触点是白银吗 -
洪冠柏18430327070 ______ 是白银的,延长使用寿命和接触良好

蔡绍路2883人民电气的ss630a的空气开关是不是银触头 -
洪冠柏18430327070 ______ 那是不可能的,最多镀一层银.abb的比人民电器贵十倍的触头也只是接触面那一小点的面积是银的,

蔡绍路2883请问电力开关或空开接触点是银子吗? -
洪冠柏18430327070 ______ 不是.最多铜镀银.

蔡绍路2883空气开关的静点是有什么材料制成
洪冠柏18430327070 ______ 旧式空开触点, 用的是纯净度较高的银! 但也有用粗铜表面包银的! 你的开关的触点, 即是包银或镀银触点! 因它内里只渗有银离子, 所以是另一种状态! 它也有可能是银包石墨掺银铜触点!

蔡绍路2883空气开关里面的金属部件是铜的吗 -
洪冠柏18430327070 ______ 是铜的,不过这种铜材料要比一般的铜线好很多,也就是纯度高,当然还有别的材料混合

洪冠柏18430327070 ______ 铜上加了一层镀膜,不是银.

蔡绍路2883空气开关上的银怎么提纯??? -
洪冠柏18430327070 ______ 用喷枪加热,加热时加少许硼砂,就可把银分离出来.

蔡绍路2883电解可不可以把空气开关里面的银提出来 -
洪冠柏18430327070 ______ 对触点来说可以但太慢,不如用机械选折的办法快.如对表面的镀层就只有用电解法了.

蔡绍路2883空气开关内部触头是并联的吗? -
洪冠柏18430327070 ______ 不是,里面是相互绝缘的.要是并联的话,一接上电源,A\B\C\N都短接到一块,就短路了.
