发布时间:2022-12-31来源://www.aqfitlab.com/浏览量:

电气成套具备电气参数灵敏准确的感知功能、系统故障的判断功能、安全可靠执行结构的操控功能。智能设备是一种高度自动化的机电一体化设备。下面来讲讲 电气成套的技术交底注意事项。
The electrical complete set has the sensitive and accurate sensing function of electrical parameters, the judgment function of system failure, and the control function of safe and reliable execution structure. Intelligent equipment is a highly automated electromechanical equipment. Now let's talk about the precautions for technical disclosure of electrical complete sets.
1、柜型、系统图、平面布置图、一次方案图、台数(XGN2、GZS1、GG-1A、GGD、PGL、MNS、GCS、GCK、GZD、PK等等);
1. Cabinet type, system diagram, floor plan, primary scheme diagram, number of units (XGN2, GZS1, GG-1A, GGD, PGL, MNS, GCS, GCK, GZD, PK, etc.);
2、柜体尺寸(长、宽、高);
2. Cabinet size (length, width and height);
3、进出线方式及架空进出线的相序(电缆上进出、电缆下进出、母排上进出、母排下进出);
3. Incoming and outgoing line mode and phase sequence of overhead incoming and outgoing lines (upper incoming and outgoing cables, lower incoming and outgoing cables, upper incoming and outgoing buses, lower incoming and outgoing buses);
4、断路器详细参数(额定电压12-31.5KV、额定绝缘电压42(28)-95(1min工频耐受电压有效值干燥状态),34(28)-85(1min工频耐受电压有效值干燥状态),75(60)-185(额定冲击耐受电压峰值干燥状态)、额定电流200,400,630,1000,1250,1600,2000,2500,3150,4000,5000、额定短路开断电流3.15,6.3,8,12.5,16,20,25,31.5,40,50,63KA)
4. Detailed parameters of circuit breaker (rated voltage 12-31.5KV, rated insulation voltage 42 (28) - 95 (1min power frequency withstand voltage effective value dry state), 34 (28) - 85 (1min power frequency withstand voltage effective value dry state), 75 (60) - 185 (rated impulse withstand voltage peak dry state), rated current 2004006301000125016000200025003150400005000, rated short circuit breaking current 3.15,6.3,8,12.5,16,20,25,31.5,40,50,63KA)

5、负荷开关详细参数、上下隔离详细参数
5. Detailed parameters of load switch and upper and lower isolation
6、电流互感器详细参数(型号、电压等级、变比、绕组数、精度、容量。注意事项:电流互感器外壳(铁壳)和二次侧须同时接地;电流互感器的二次侧不允许接闸刀和熔断器;电流互感器的二次回路连接导线应用绝缘软铜线,截面不得小于1.5mm2,不得使用铝导线;电流互感器二次回路的负荷不得大于对应的一定精确度的额定值;运行中电流互感器,二次侧不得开路。)
6. Detailed parameters of current transformer (model, voltage class, transformation ratio, number of windings, accuracy and capacity). Precautions: the shell (iron shell) of current transformer and secondary side must be grounded at the same time; The secondary side of current transformer shall not be connected with knife switch and fuse; The secondary circuit connecting conductor of current transformer shall be insulated flexible copper wire, with the section not less than 1.5mm2, and aluminum conductor shall not be used; The load of secondary circuit of current transformer shall not be greater than the corresponding rated value with certain accuracy; The secondary side of current transformer in operation shall not be open circuit.)
7、熔断器详细参数(RN2熔断器不能作过载保护,如需要对电压互感顺过载加以保护时,则可在电压互感器的低压侧装置低压熔断器。如果要使用于短路容量大于2000兆伏安的线路上时,则应在熔断器前串联限流电压。标准参数:额定电压(KV)、额定电流(A)、额定开断容量(MVA,RN1<200\RN2<1000))
7. Detailed parameters of fuse (RN2 fuse cannot be used for overload protection. If it is necessary to protect the voltage transformer from overload, a low-voltage fuse can be installed on the low-voltage side of the voltage transformer. If it is to be used on lines with a short circuit capacity greater than 2000 MVA, the current limiting voltage should be connected in series in front of the fuse. Standard parameters: rated voltage (KV), rated current (A), rated breaking capacity (MVA, RN1<200 RN2<1000))
8、电压互感器详细参数(型号、电压等级、变比、绕组数、精度、容量。注意事项:电压互感器外壳(铁壳)和二次侧必须同时接地,以降低高压窜入低压造成的危险性;电压互感器的一二次绕组都应接熔断器,以防止二次侧工作时接地和短路;电压互感器的二次回路连接导线应用绝缘软铜线,截面不得小于1.5mm2,不得使用铝导线;电压互感器二次回路的电压降不应超过0.5%,对0.5级电能表不得超过0.25%。)等等。
8. Detailed parameters of voltage transformer (model, voltage grade, transformation ratio, number of windings, accuracy and capacity). Precautions: the shell (iron shell) and secondary side of voltage transformer must be grounded at the same time to reduce the risk caused by high-voltage channeling into low-voltage; The primary and secondary windings of the voltage transformer shall be connected with fuses to prevent grounding and short circuit when the secondary side is working; The secondary circuit connecting wire of voltage transformer shall be insulated flexible copper wire, with the section not less than 1.5mm2, and aluminum wire shall not be used; The voltage drop of the secondary circuit of the voltage transformer shall not exceed 0.5%, and it shall not exceed 0.25% for the class 0.5 electric energy meter.) wait.
