Features and Design of AC and DC Switchboards
It so happened that electricity plays one of the main roles in the life of every second modern person. Without it, it is difficult to imagine not only our existence, but also the work of industrial enterprises. That is why it is so important to ensure its stable and continuous operation — AC and DC circuit boards were created for these purposes.
Purpose and function of the DC shield
The DC board is a specialized equipment whose main task is continuous power supply of channels for operational control, network protection, automation and notification of electrical substations and power plants, in addition, they can be used in a wide variety of industrial enterprises.
The main functionality of DCS is:
-
Power supply from rechargeable batteries, as well as their recharging through the chargers built into the panel.
-
Redistribution of power between users
-
Creating a "blinking light" bus
-
Protection of inputs from interruptions and short circuits
-
Allows connection of different busbars with sectional connectors
-
Continuous automated control of current resistance
-
Quick identification of the shorted line
-
Measuring the main indicators of batteries
-
Light indication of the status of devices with a direct current board
DCB design
The panel board is mainly made of several sections of floor cabinets, which are rectangular frame structures with side and back walls, as well as front doors. At the same time, the inner decoration is made using zinc coating, and the outer one using powdered enamel. All the internal equipment of the DCB is installed on special panels, elements and sensors for control and visual indication — on the front doors of the board.
Purpose and function of AC shield
An AC switchboard is a complex low-voltage switchgear used to receive and further separate power supply and short-circuit protection... Such shields are designed to provide:
-
Feeding consumers
-
Automatic collection of fault notifications received from other devices in the electrical installation
-
Equipment for automatic switching on / switching on
-
Input and output voltage level monitoring
-
Measurement and control of voltage in batteries and so on.
AC circuit board construction
In nine out of ten cases, such a shield is made in the style of a one-way service cabinet. The side panels of the switchboard have openings that are necessary for installing uninterruptible power supplies.Inside the AC switchboards are usually installed devices for starting and blocking backup electrical substations, as well as equipment for monitoring the voltage supplied to the guaranteed power bus.
After all, AC and DC panels are indispensable equipment that are present not only in large enterprises, factories and production workshops, but also equipment that can find application in people's living conditions, for example, for the protection of electronics or the continuous supply of electricity.
