AGU-50 is an electrical control and protection system for underground mining operations. It is designed to provide fail-safe stop and start control of electrical equipment and protect it from overload and short circuit damage. The system is used in underground coal and metal mining applications where the equipment installed is powered by either medium voltage (MV) or low voltage (LV) direct current (DC) high amperage electricity.The system consists of the AGU-50 control and protection unit, which is connected to the main distribution board and other field equipment such as motor starter or control relay panels. It is capable of safely controlling and protecting electrical systems that draws up to 1000 amperes (A) at 1000 volts (V). The AGU-50 also provides continuous monitoring and reporting of system conditions, with outputs available for remote control.The AGU-50 control and protection unit consists of three different basic components: the main control board, the power supply board, and the fuser. The main control board contains the logic and circuit breakers that control the operation of the system. It also contains logic to monitor motor current and temperature, as well as providing protection against short circuit and over-temperature.The power supply board provides power to the main control board and other field equipment. It consists of a DC-DC converter, battery, and charging circuit. The battery is used to store energy to prevent voltage drops during motor starting or other high current applications. The charging circuit ensures that the battery is charged and ready to provide energy in case of a power failure.The fuser is the last component of the AGU-50 control and protection unit. It controls the motor protection relays and the protective circuit breakers. It also monitors the motor current, temperature, and voltage. In the event of a short circuit or over-temperature, the fuser will open the circuit breakers to stop the motor and protect it from further damage.The AGU-50 control and protection system is designed to provide fail-safe stop and start control of electrical equipment and protect it from overload and short circuit damage. Its features include automatic motor protection, sensing current to detect motor overloading, and a programmable logic controller to enable programmable control of the system.The AGU-50 system is an important part of underground mining systems for safe operations. It provides the necessary safety features to prevent accidents and damage to employee and equipment. Additionally, it offers operational and cost benefits due to increased operational efficiency. With its robust design and automatic protection features, the AGU-50 can provide reliable and long-lasting operation of underground mining systems.
