GGD Control Cabinets in the Mining Industry

# Structural Features

- **Sturdy and Durable**: The mining environment is complex, with a large amount of dust, vibrations,

 and possible rock impacts. The cabinet frame and side panels of the GGD control cabinet are usually 

made of high-strength cold-rolled steel plates, with a thickness generally of 2.0 mm or more. They can 

withstand a certain degree of external impacts and prevent the cabinet from being damaged due to 

accidental collisions or falling rocks during mining operations.

- **Sealed and Dustproof**: Tighter sealing measures and an efficient air filtration system are adopted,

 which can filter out most of the dust and prevent it from entering the inside of the cabinet to affect the

 normal operation of electrical components. Meanwhile, high-quality sealing strips are used between the 

cabinet door and the cabinet body to ensure the tightness when the door is closed.

- **Moisture-proof and Drainage**: To adapt to the potentially humid environment underground in the

 mine, the GGD cabinet is equipped with moisture-proof and drainage facilities inside. For example, drainage 

holes and drainage pipes are set at the bottom of the cabinet body to drain accumulated water in a timely 

manner. Moisture-proof heaters or desiccants are installed inside to reduce the humidity inside the cabinet,

 ensuring that stable and reliable power can be provided for mining equipment in the harsh mining environment.

### Electrical Performance

- **High Current-carrying Capacity and Short-circuit Withstand Capacity**: Mining equipment has relatively 

high power, so the busbars and electrical components of the GGD cabinet need to have higher current-carrying

 capacity and short-circuit withstand capacity. The busbars are usually made of copper bars or aluminum bars.

 Copper bars have better electrical conductivity and corrosion resistance, but their cost is relatively high. 

Aluminum bars have a certain cost advantage and can meet the requirements in some occasions where the

 demand for electrical conductivity is not extremely high. Meanwhile, the rated current and short-circuit 

breaking capacity of electrical components such as circuit breakers and contactors in the GGD cabinet will 

also be selected according to the actual needs of mining equipment. Generally, the rated current can reach

 several thousand amperes, and the short-circuit withstand current is between dozens of thousand amperes

 and hundreds of thousand amperes.

- **Good Electromagnetic Compatibility**: A reasonable layout of components can reduce electromagnetic

 interference and improve the electromagnetic compatibility of the cabinet. When arranging the components, 

the high-voltage components and low-voltage components are separated. For example, high-voltage control 

components such as relays and contactors are kept at a certain distance from low-voltage components such

 as measuring instruments and controllers. This can prevent the electromagnetic fields generated by high-voltage

 components during operation from interfering with the signals of low-voltage components.

### Functional Configuration

- **Convenient Operation**: The layout of the operation panel is reasonable, and the function keys are clear, 

making the operation convenient and less prone to errors. Meanwhile, to facilitate the operation of operators 

underground in the mine, some GGD control cabinets are also equipped with lighting devices and emergency

 stop buttons, etc.

- **Intelligent Monitoring**: They can be equipped with an intelligent monitoring system. Through various 

communication technologies and interfaces, such as the Modbus communication protocol and Ethernet 

communication, parameters such as voltage, current, and temperature inside the cabinet can be transmitted 

to a remote monitoring center or users' mobile devices, realizing remote monitoring and management of

 the cabinet. Once abnormal situations such as overload and overheating occur, the monitoring system 

will immediately issue an alarm and can be linked with the mine's automated management system to realize 

operations such as automatic circuit switching or starting of backup power supplies, ensuring the uninterrupted

 power supply to mining equipment.

- **Overload, Short-circuit and Leakage Protection**: Protective components such as circuit breakers, fuses, 

and thermal relays are installed inside the GGD control cabinet, which can provide protection against overload, 

short-circuit and leakage of the circuit. When faults such as overload, short-circuit or leakage occur in the circuit, 

these protective components can quickly cut off the circuit, prevent the expansion of the faults, and protect the

 safety of mining equipment and personnel.

### Application Scenarios

- **Power Distribution on the Surface of the Mine**: In the ground industrial square of the mine, such as ore 

dressing plants, machine repair shops, warehouses and other places, the GGD control cabinet can be used 

to provide power distribution and lighting distribution for various production equipment, lighting systems, 

office equipment, etc. For example, it can provide a stable power supply for equipment such as crushers, 

ball mills, and flotation machines in the ore dressing plant to ensure the normal progress of production 

processes such as ore crushing, grinding, and flotation.

- **Power Distribution Underground in the Mine**: Underground in the mine, the GGD control cabinet 

can be used to provide power control and protection for underground mining and transportation equipment 

such as roadheaders, coal cutters, scraper conveyors, and hoists. Due to the harsh underground environment,

 higher requirements are placed on the protection level and explosion-proof performance of the GGD control 

cabinet. Usually, explosion-proof GGD control cabinets need to be adopted to ensure safe and reliable operation

 in environments with flammable and explosive gases such as gas and coal dust.
