两相空气开关又称2P空气开关，它的接线如下图所示，如果空气开关没有标记L与N，那就按照左零右火的习惯接线就好。一般空气开关用在线路中作为总开关，而漏电开关作为支路的开关，所以正常的接法应该是空气开关－－漏电开关。为什么要这样接呢，从它的功能上我们就可以知道，如果把漏电开关接在空气断路器的前面。因为漏电开关一旦出现漏电就会切断电源，而空气开关在这个时候不会作出反应，就会导致越级跳闸的现象出现。

The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 square, tell from some cable, power cable according to the demand of power grid more generally for 5 core, and control cable transmission control, some more, according to the terms of more than 61 core, but also can produce according to user re

Spin cassette XF5-273 communication cable transfer box, adopting advanced technology at home and abroad, in accordance with the international advanced standard production in the eighty s of cable wiring e, for the city, the town of telecommunication network backbone cable and wiring cable transfer. Features: 1. The connection jumper adopts rotary clamp-type connection and is sealed with silica gel on the metal clip, because it is not only reliable and durable, but also easy to operate and repair without stripping. 2. The wiring terminals in the handover box shall be arranged in 25 pairs as a basic unit, consistent with the basic units of the local telephone cables and marked with Numbers on the terminals to facilitate construction and maintenance. 3. The structure, arrangement and installation dimensions of the wiring modules are exactly the same as those of 3M products and can be used for each other. 4. The box body is treated by electrostatic spraying, beautiful and generous, with clear lines, good anti-corrosion and waterproof performance and long service life. Main technical parameters: the environment temperature: - 40 ℃ ~ + 65 ℃ atmospheric pressure: 70 ~ 106 kpa relative humidity: 95% or less is random ends and insulation resistance between terminals and ground > 5 x 104 Μ Ω. When connecting any two ends and any terminals and grounding to 1000V ac, there shall be no breakdown or flying arc in 1min. Contact resistance between wire and terminal < 5 x lO - 3 Ω.

一位LED数码显示单元电路如所示。WR与A8(P2.0)相或提供74LS273的时钟信号，当执行“MOVX@DPTR，A”指令时，地址信息由DPTR寄存器确定，会出现有效的写信号WR，只有当地址A8为满足“0”时，写信号才可以作为74LS273的时钟信号输入，完成数据锁存。P2口为A8～A15的8位地址线，很容易扩展到8只LED数码管，WR信号分别与A8～A15按或关系连接，每位地址线均为低电平有效，即可实现8个有效地址。
