With the trend of ultra-large-scale circuits, system integration, component miniaturization, and high-density PCB surface mounting, the market's demand for automatic frequency converter continues to heat up. With the continuous application of new materials and new processes, manufacturers of Siemens 6SE6430 series inverters continue to research and innovate frequency converter with various structures to meet the needs of different market applications.
Here is the content list:
What factors disturb smooth operation of Siemens 6SE6430 series inverters?
How to implement protection measures of Siemens 6SE6430 series inverters?
What development will Siemens 6SE6430 series inverters have in the future?
As the high-density frequency converter has been put into application for more than half a century, and its main advantage is to reduce the consumption of electrical energy. It is precisely because of the changing needs and applications that there are many things that need to be paid attention to in the use process.
With the development of Industry 4.0, it has become the dark horse in this industrial revolution. Automatic Siemens 6SE6430 series inverters transform their inverters from pure power processing devices to intelligent components for automation systems. However, in actual use, there are some interference factors that make it unable to play its best role.
Poor operating environment
If the humidity in the working environment of Siemens 6SE6430 series inverters is too high, the internal insulation will cause discharge breakdown, resulting in moldy PCB boards, leading to wire breakage or poor contact of connectors, and also accelerate the oxidation of some metal structures, leading to the main circuit or power terminals Poor contact of the row.
When the working environment of Siemens 6SE6430 series inverters contains corrosive gas, the environment is too dirty or too oily, it will damage the PCB board and small electronic components greatly, which will significantly reduce the service life of the inverter.
Short circuit
Although Siemens 6SE6430 series inverters have very fast over-current detection and protection circuits, the large current value during short-circuit will cause the semiconductor device to withstand huge stress.
The short circuit may be caused by a short circuit between the motor phases, a short circuit between the motor and the ground, poor insulation of the motor cable, or a short circuit between the motor and the ground. Frequent output short circuits, especially output to ground short circuits, can cause very fatal damage to the inverter.
Input grid and surge voltage
Input surge voltage or surge voltage will cause fatal damage to the Siemens 6SE6430 series inverters input rectifier module. Since the grid voltage surge comes from the outside, Siemens 6SE6430 series inverters cannot be used for active protection, and only the operator can implement protective measures.
How to implement protection measures of Siemens 6SE6430 series inverters?
Operators must be familiar with the basic working principles and functional characteristics of Siemens 6SE6430 series inverters, and have common sense of electrician operation.
Before performing routine maintenance on the frequency converter, it is necessary to ensure that the total power supply of the equipment is cut off; and perform the operation after 3-30 minutes after the frequency converter display disappears completely.
Cooling fan
The power module of Siemens 6SE6430 series inverters is the most serious device, and the heat generated by its continuous operation must be discharged in time. According to the continuous operation of the inverter, the fan must be replaced once every 3 to 5 years to avoid malfunctions caused by poor heat dissipation.
Filter capacitor
The filter capacitor needs to store energy during operation, so it must be energized for a long time. The heat generated by its continuous operation and the heat generated by the Siemens 6SE6430 series inverters will accelerate the drying of its electrolyte and directly affect its capacity.
The service life of the capacitor is 5 years under normal conditions. It is recommended to check the capacity regularly once a year. Generally, the filter capacitor should be replaced if the capacity is reduced by more than 20%.
Preservative
Due to the production characteristics of some companies, the concentration of corrosive gas in electrical mcc chamber is too high, causing Siemens 6SE6430 series inverters to be damaged by corrosion. In order to solve this problem, an air conditioning system can be installed and positive pressure fresh air can be used to improve environmental conditions.
Dust removal
According to the different use environment, you should regularly check the Siemens 6SE6430 series inverters heat dissipation channel and circuit board for accumulated dust, and clean it once every six months to ensure that the inverter has good heat dissipation to avoid malfunctions.
What development will Siemens 6SE6430 series inverters have in the future?
For fans who care about the Siemens 6SE6430 series inverters, the update of this series is also a joy to see. Automation and artificial intelligence are pushing to the extreme what Siemens 6SE6430 series inverters can do. Of course, the technological advancements of Siemens 6SE6430 series inverters are inseparable from the teamwork and capital investment behind which.
In order to reduce production costs, many frequency converter companies rely on the replacement of electronic components, the replacement of materials and the simplification of circuits.
This may eventually lead to a situation where the reliability of the frequency converter is sacrificed in exchange for short-term benefits. In the long run, this will be very detrimental to the healthy development of the entire frequency converter industry.
On the contrary, Shenzhen Juson believes that to promote the development of the industry, innovate automatic frequency converter products with better performance and more adaptability, it is necessary to rely on technological innovation to effectively improve the profitability of the company, instead of deliberately reducing costs through the choice of cheap components.
The continuous challenges of the industrial field to the performance of the whole machine will inevitably drive the development of electronic frequency converters in the direction of high frequency, low loss, surface mount, new materials, and new structures. Shenzhen Juson Automation Company Limited. supports a variety of Siemens 6SE6430 series inverters services to provide our customers with feasible frequency converter choices and achieve a wide range of social economic benefits.
