State Instrument

,指的是开关柜里面的主设备(有断路器、电流互感器、电压互感器、隔离开关、避雷器等等)及其电气连接,将这些连接起来画到纸上图纸就是一次系统图 。 The primary system in the switch cabinet refers to the main equipment (including circuit breakers, current transformers, voltage transformers, disconnectors, lightning arresters, etc.) in the switch cabinet and their electrical connections. Draw these connections together on paper. Is a system diagram . Its role is to transmit, control and protect electrical energy.

Primary equipment refers to high-voltage electrical equipment that directly produces, transmits, and distributes electrical energy. It includes generators, transformers, circuit breakers, disconnectors, automatic switches, contactors, knife switches, bus bars, power transmission lines, power cables, reactors, motors, and so on. 。 Electrical circuits that are connected to each other by primary equipment to form power generation, transmission, distribution, or other production are called primary circuits or wiring systems .

格式,查看DWG格式的文件需要专用软件AUTOCAD打开图纸. Generally, it is in DWG format.Viewing files in DWG format requires special software AUTOCAD to open the drawings.

The following figure is an example:

When customizing the switch cabinet intelligent control device or switch status indicator , the required simulation diagram is part of it:
