电表怎么看度数呢?
添加时间:2019/3/11 14:10:50     浏览次数:
一般的直进式的单相电表和三相电表可直接读取数字,减去上次的读数就为这一阶段的电量。
General single-phase and three-phase ammeters can read digits directly, subtracting the last reading for this stage of electricity.
三相电表怎么看度数,三相电表通过电流互感器连接方式连接的三相电表,电表的接线有10根接线,要观察连接的电流互感器的电流比,电流互感器的名牌上有,都是一个数字比5标出的,例如 100/5 150/5 等,电表上读取的数字乘以电流比就是计量的电量,精确的还要加上变损和线损。
How to see the degree of three-phase ammeter? Three-phase ammeter is connected by current transformer. The connection of three-phase ammeter has 10 wiring. To observe the current ratio of the connected current transformer, there is a number on the name plate of the current transformer. For example, 100/5 150/5, etc. The number read by the ammeter multiplies the current ratio by the quantity measured, which is more accurate. Add variation and line loss.
单相电表怎么看度数,单相电表计量三相电的电量,电量读取方式是直进式的连接电表的方式,读取电表上的数字乘以3,若通过互感器连接的电表要读取电表数字乘以互感器电流倍数再乘以3。
How to look at the degree of single-phase ammeter? Single-phase ammeter measures three-phase electricity. The way of reading electricity is to connect the ammeter directly. Reading the number of ammeter multiplied by 3. If the ammeter connected by transformer is to read the number of ammeter multiplied by current multiplier of transformer multiplied by 3.
智能电表怎么看度数,智能电表只有一个液晶屏,如果是单相里面会直接显示总有电量和剩余电量,直接读数就可以。如果是IC卡电表,只有发光管显示就是单显卡表,那电表上面上会有个小红点。红色的小点跳到总用那里就是总用,,跳到剩余那里就是剩余。双显卡表,读上面或下面都可以。三相的预付费电表直入式的直接读数。互感式的用表的读数乘以互感器倍率。

How to look at the degree of smart meter? Smart meter has only one LCD screen. If it is in a single phase, it will show the total and residual electricity directly, and it can read directly. If it is an IC card www.oushibilu.cnwww.quyangshidiao.net.cnwww.quyangdiaoke.net.cnwww.renwushidiao.com.cn

www.shibeidiaoke.cnwww.rewudiaosu.cnmeter, only the light emitting tube display is a single display card meter, and there will be a small red dot on the meter. Red dots jump to the total use is the total use, jump to the rest is the surplus. Double graphics card table, read above or below. Direct reading of Three-phase Prepaid meter. The reading of the mutual inductance meter is multiplied by the transformer multiplier.
