Description

Technical Field

[0001] The invention belongs to the technical field of steelmaking equipment, and in particular relates to a UPS power supply control system and a use method thereof and an application on a crane. Background Art

[0002] As heavy machinery, the operation of cranes is highly dependent on stable power supply. Power fluctuations or interruptions may cause sudden equipment shutdown, which not only affects work efficiency, but may also cause safety accidents such as cargo falling and equipment damage. Therefore, the emergency power supply system needs to have the ability to respond quickly and output stably to ensure seamless takeover of power supply tasks in the event of a power grid failure.

[0003] The emergency power supply system in the prior art may not be able to start quickly and provide stable power support when the main power supply is interrupted, causing the crane to suddenly shut down when the power fluctuates or is interrupted, affecting work efficiency and even causing safety accidents. The power control system in the prior art cannot adapt well to the working requirements of the crane under different environmental conditions (such as high temperature, low temperature, humidity, dust, etc.), resulting in its performance degradation or increased failure rate. The original technology may not be equipped with sufficient emergency lighting devices and cannot provide sufficient light in the event of a city power outage or other emergency, affecting the safety of operators and the normal operation of equipment.

[0004] UPS is a core component of the emergency power supply system. It can start immediately when the main power supply is interrupted and provide power support for the crane for a period of time until the backup power supply (such as a diesel generator) starts and takes over the power supply. UPS usually uses battery packs as energy storage elements, combined with advanced power electronic conversion technology to achieve smooth conversion and stable output of electrical energy. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a UPS power supply control system and a method for using the same and an application on a crane.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A UPS power supply control system, the system includes a mains power supply, a rectifier, an inverter, a transformer, a battery pack, a charger, a communication device, an alarm device, an emergency lighting and a load, wherein the output end of the mains power supply and the input end of the rectifier and the charger are connected, the output end of the charger is connected to the input end of the battery pack, the output end of the rectifier and the output end of the battery pack are connected to the input end of the inverter, the output end of the inverter is connected to the input end of the transformer, and the output end of the transformer is connected to the load, the emergency lighting, the communication device and the alarm device;

[0008] The mains is the input power source of the system, which can provide the original alternating current. The rectifier can convert the alternating current of the mains into direct current. The inverter converts the direct current output by the rectifier into alternating current again to adapt to the needs of the load. The transformer is used to adjust the voltage in the circuit to ensure the stable operation of the system. The battery pack is used as a backup power source to provide power support when the mains is interrupted. The charger is used to charge the battery pack to ensure that the battery pack always maintains a certain amount of power. The communication device is used to monitor and process noise or interference in the circuit to ensure clear and accurate signal transmission. The alarm device will sound an alarm when the circuit fails or an abnormal situation occurs, reminding the operator to deal with it in time. The emergency lighting is activated when the system needs it, providing emergency lighting to ensure that there is enough light in the event of a mains interruption or other emergency. The load is the terminal of the circuit and consumes electrical energy to work.

[0009] The method of using the UPS power control system on the crane as described above is as follows:

[0010] (1) The UPS power control system first receives AC power as the original power supply through the mains;

[0011] (2) AC power is converted into DC power through a rectifier, and the charger inputs the power of the mains into the battery pack, which then stores the power;

[0012] (3) If the load requires AC power, the DC power is then converted back into AC power through an inverter.

[0013] (4) The transformer adjusts the voltage level to ensure that the voltage is within the acceptable range for the load;

[0014] (5) After rectification (and inversion) and voltage regulation, the power is transmitted to the load, driving the load to perform normal work;

[0015] (6) If an emergency occurs and the AC power is cut off, the battery pack replaces the AC power and rectifier to discharge to the inverter, and the system automatically switches to the backup power supply, connecting the load, emergency lighting, communication devices and alarm devices, so that the equipment can still operate normally when a fault occurs.

[0016] Furthermore, the UPS power supply control system also includes a PLC control system, and the PLC control system is connected to the inverter.

[0017] Furthermore, it is characterized in that: the inverter is an inverter using IGBT (insulated gate bipolar transistor) inverter technology.

[0018] The advantages and positive effects achieved by the present invention are:

[0019] 1. The UPS power control system of the present invention can start immediately when the main power supply is interrupted, providing stable power support for the crane, ensuring that the equipment will not stop suddenly, improving work efficiency and avoiding safety accidents. The UPS power control system has good environmental adaptability. It realizes smooth conversion and stable output of electric energy, meeting the strict requirements of the crane for power supply.

[0020] 2. In the UPS power control system of the present invention, the battery pack serves as the backup power supply of the system, providing power support when the city power is interrupted or the main power supply is insufficient. When the system needs it, the emergency lighting can be started to provide emergency lighting, providing safety protection for the operator. The reliability of the overall crane system is improved, the equipment downtime caused by power supply problems is reduced, and the production efficiency is improved.
