Brief Introduction to the Structure显示装置的传感器和显示器经外接导线，联通成电容分压回路（见图1原理图）The sensor and the display of the display device are connected by external wires into the capacitance voltage-dividing circuit (see the schematic diagram of Figure 1).High voltage bus Capacitor C2 Resistor RNeon lamp NDCapacitor C1Sensor Display图1Figure 13.1 传感器3.1 Sensor传感器制成支柱绝缘子式，内埋高强介电功能性材料制成芯棒式电容C1、其C1的一端经上法兰与高压母线连接，C1另一端由传感器下端（二次接线端）连接（见图2），传感器的外形结构根据配套要求，制成不同高度和各式伞裙（如图47所示）。根据安装要求，上法兰制成有单螺孔、双螺孔、四螺孔（具体孔径、孔距、孔数见表2）。传感器的外绝缘结构有以下二种：The sensor is made in the post insulator style which is internally buried with core-rod style capacitor C1 made of high dielectric functional material. One end of the capacitor C1 is connected with high voltage bus via the upper flange while the other end is connected with the lower end of the sensor (secondary connection terminal) (see Figure 2). According to requirement of operation the outline structure of the sensor can be made in different heights and different umbrella skirts (shown as in Figure 4-7). According to requirement of installation, the upper flange has single screw hole, double screw holes and four screw holes (detailed diameter of hole, distance of holes and number of holes are shown in Table 2). The outer insulation structure of the sensor has two kinds as follows:a. 用环氧树脂制成的外绝缘套，中间埋设高压电容C1，制成的传感器其型号CG3型（见图2）a. The outer insulation sleeve made of epoxy resin with high voltage capacitor C1 buried inside. The model of the finished sensor is CG3 (see Figure 2).b. 具有阻燃性，憎水性的SMC材料制成的外绝缘套与高压电容C1，制成的传感器，其型号为CG2（见图3）。b. The sensor is made of the outer insulation sleeve which is made by flame-retarded and hydrophobic SMC material and the high voltage capacitor and the model is CG2 (see Figure 3).Figure 2 Figure 31. 上法兰 Upper flange2. 强介电容C1 Strong dielectric capacitor C13. 壳体Sleeve4. 下法兰 Lower flange5. 二次接线端Secondary wiring terminal Direction AFigure 43.2 显示器3.3 Display显示器功能有：提示型和强制性。提示型有单显示（即三只传感器配一只显示器，接线原理见图10）和双显示（即三只传感器配套二只显示器，接线原理同单显示），二只显示器分别安装在开关柜的两个不同侧面。提示型号氖灯不允许休止。强制型：它不但具备提示型的全部功能，而且利用抽压信号控制电子开关，配合电磁锁强制闭锁。当三相回路只有一相带电时，电磁锁就不能解锁。显示器中的直键开关是作为氖灯工作与休止状况选择用，当氖灯处于休止状况时强制闭锁回路不得解锁，（接线原理见图11）。 The display has functions as follows: the prompt type and the compulsory type. The prompt type has single-display (that is, three sensors incorporated with one display and wiring principle is shown in Figure 10) and double-display (that is, three sensors incorporated with two displays and wiring principle is the same with that of the single-display). Two displays are mounted on two different sides of the switch cabinet separately and the neon lamp for the prompt type is not allowed to halt. For the compulsory type, it has no all functions the prompt type has and electronic switch is co
