AC screens and DC screens are generally used together during use. They are two common types of power distribution screens. Due to the differences in output, usage, and other aspects, today we analyze the specific differences between the two types of power distribution screens. Department.

First, the definition is different.

AC power distribution screen (abbreviated as AC screen) is based on different electrical equipment and different power consumption, and is generally controlled by a branch switch composed of a voltmeter, ammeter, switch (or automatic switch), insurance, signal lamp, and line. In the entire power system can monitor the total voltage, current or branch voltage, current usage, according to the required conditions switch branch.

The DC panel is mainly used to provide DC power to the high-voltage switchgear, control system, comprehensive protection, instrumentation, and accident lighting.

Second, the output is different.

The input power of the AC panel and the DC panel is AC, but the output is different. The AC panel outputs AC, and the DC panel outputs DC.

When the AC power failure occurs, the AC panel has no output, and the DC panel can still output DC power.

The AC panel is essentially a low-voltage power distribution cabinet, with AC input and output, and it is generally matched with a DC panel to provide power distribution for DC panels and power distribution rooms.

Third, the nature is different.

The DC panel converts AC to DC to charge the battery. When the mains power is cut off, the battery is used to power the busbar to the high-voltage closing and closing system and the control system and the comprehensive protection to provide power.

Fourth, use different.

The function of the AC panel is to display the operating status of the various high and low voltage distribution cabinets. Generally, there are current, voltage display, and closing and closing instructions.

DC screens are used in large, medium, and small power plants and substations to provide DC power for high-voltage switches in the normal operation and accident conditions, such as switching on and off, relay protection, automatic control, and accident lighting. The reliability of the DC screen is irreplaceable for other power supply devices. It can meet the high reliability requirements of the power supply in substations and power plants.

In fact, whether it is a DC screen or an AC screen, it has an extremely important role in practical applications. The difference between them provided by Xiao Bian is just to make everyone understand the DC screen and the AC screen clearly. The above is for reference only.
