From understanding the crusher power distribution system to how to repair it

September 21, 2023    Hawk

The crusher‘s power distribution system is a complex power system that is responsible for delivering power from the source to various parts of the crusher to ensure that it can operate safely and efficiently. The following are some of the major components of a power distribution system:


  1. Power supply: The power supply is the starting point of the power distribution system, which can be a public power grid or a dedicated generator. The public power grid usually provides stable AC power, but in some cases, a generator may be needed to provide power, especially in locations far away from the grid. Generators can be fuel, diesel, or natural gas powered and can provide AC or DC power.


  1. Distribution box: The distribution box is the core of the power distribution system. It receives power from the power source and distributes it to various parts of the crusher. Distribution boxes usually contain protective devices such as circuit breakers and fuses to protect the power supply from overloading. A circuit breaker is an automatic switch that opens a circuit when the current exceeds a set value, preventing the power supply from overloading. The fuse is a one-time protection device. When the current is too large, the fuse will blow and cut off the circuit.


  1. Transformer: Transformer is an important part of the power distribution system, which adjusts the voltage to the appropriate level. The working principle of a transformer is to use the principle of electromagnetic induction to change the voltage through changes in the magnetic field between two or more coils. Transformers usually consist of an iron core that guides the magnetic field and coils that generate and receive voltage.


  1. Controller: The controller is an electronic device used to control the distribution of power and the operation of the crusher. The controller can adjust the flow of power as needed to optimize the crusher’s performance. The controller usually contains some sensors and actuators. The sensors are used to monitor the flow of power and the status of the crusher, and the actuators are used to control the distribution of power and the operation of the crusher.


  1. Wires and Cables: Wires and cables are the physical media of power distribution systems and are used to transmit power within the system. Wires and cables must be strong enough to withstand the flow of electricity and must be properly insulated to prevent electric shock. Wires are usually made of conductive material (such as copper or aluminum), while cables are composed of one or more wires wrapped in a protective coating.


  1. Ground wire: The ground wire is a safety device in the power distribution system. It is used to guide current to the ground in the event of a power failure to prevent electric shock. A ground wire is usually made of a conductive material and is connected to a power source or appliance on one end and to the ground on the other end.

This system requires regular maintenance and inspection to ensure it is functioning properly. If there are any problems, you should stop using the crusher immediately and contact a professional for repair. The design and maintenance of power distribution systems require professional knowledge, so if you are not a professional, it is not recommended to do it yourself.


When there is a problem with the crusher’s power distribution system, it should be detected and repaired by professional electricians or maintenance personnel. Here are some possible steps:


  1. Preliminary inspection: First, turn off the power and disconnect all power connections, then conduct a visual inspection. Check for damage to wires, cables, and ground wires, and for signs of burnt or melted distribution boxes and controllers. Also, check that all electrical equipment is properly installed and secured.


  1. Use testing equipment: Use professional equipment such as voltmeters, ammeters, and insulation resistance meters for testing. Check whether the power supply voltage is normal, whether the current is excessive, and whether the insulation of wires and cables is intact. If any abnormalities are found, the damaged parts may need to be replaced.


  1. Check the protective equipment: Check whether the circuit breakers and fuses in the distribution box are working properly. If a circuit breaker keeps tripping or a fuse blows frequently, it may indicate an overload or short circuit problem in the circuit. In this case, it may be necessary to adjust the circuit design or replace the protection device with a higher specification.


  1. Check the controller: Check the working status of the controller and see if there are fault codes or warning messages. If so, follow the manufacturer’s instructions for troubleshooting and repair.


  1. Repair and replacement: If any damaged parts are found, they should be replaced immediately. When replacing wires or cables, make sure the new part meets the system’s electrical specifications. When replacing protective devices or controllers, ensure that the new parts are compatible with the rest of the system.


  1. Retest: After repair, test again to ensure that all components are working properly, the power supply voltage and current are within the normal range, and there are no short circuit or overload problems.


  1. Regular maintenance: In order to prevent the problem from recurring, regular maintenance and inspections should be carried out. This includes cleaning distribution boxes and controllers, checking the insulation of wires and cables, testing the working condition of protective equipment, and more.


Please note that electrical work can be very dangerous and you should not attempt to perform inspections and repairs yourself if you are not a professional. If you’re not sure what to do, contact a professional immediately.
