        Detailed introduction


        Electric control cabinet




        It is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in enclosed or semi-enclosed metal cabinet or screen according to the requirements of electrical wiring. Its arrangement should meet the requirements of normal operation of power system, facilitate maintenance, and not endanger the safety of personal and surrounding equipment. Including (distribution cabinet) (distribution box) (electrical control cabinet), etc., in normal operation, can be connected or disconnected by manual or automatic switches. When a fault or abnormal operation occurs, the circuit is cut off or the alarm is given by means of a protective device. By means of measuring instrument, various parameters in operation can be displayed, some electrical parameters can be adjusted, and the deviation from normal working state can be prompted or signaled. It is often used in power generation, distribution and substation.




        Generally, the secondary line of low-voltage electronic control cabinet, the minimum distribution cross-section area of voltage line is 1.5 square, the minimum cross-section area of current circuit is 2.5 square. Current circuit refers to the current signal line of current transformer, ammeter, power factor meter, current signal line of mutual inductance ammeter, etc. The current flowing through is 5 amperes. In addition, the power line is yellow-green-red, zero-line blue or light blue (some are grey). Because international standards also distinguish between European standards and American standards. The main line of the circuit is at least 1.5 square millimeter black line, the control line is 1.0 square red line with AC voltage, and the DC voltage is 1.0 square blue line. Signal line color is not required.
