In the industrial production environment, safety is always the top priority. Especially in petrochemical, coal mine, pharmaceutical and other flammable and explosive places, a tiny electrical spark may lead to disastrous consequences. Today, let's talk about the control panel of high-voltage explosion-proof brushless fan, a seemingly ordinary but vital industrial safety equipment.
Core value of explosion-proof control panel
The control board of high-voltage explosion-proof brushless fan is not an ordinary circuit board, it is a safety guardian specially tailored for dangerous environment. To put it simply, this control panel is designed with a special explosion-proof structure to seal the electrical components that may generate sparks, arcs or high temperatures in an explosion-proof housing to prevent direct contact with external flammable and explosive gases. Even if there is an internal fault, the danger can be prevented from spreading to the external environment through the isolation function of the explosion-proof shell.
The working principle of this control panel is actually quite interesting. It uses the three-phase inverter bridge circuit as the core, works with MOS tube through driving chips such as IR2101S, and cooperates with SVPWM modulation technology to convert direct current energy into three-phase alternating current with a phase difference of 120, so as to accurately control the operation of the fan motor. The whole process forms a closed-loop control to ensure stable operation under severe working conditions.
Technical characteristics and application scenarios
The technical characteristics of the control panel of high-voltage explosion-proof brushless fan are mainly reflected in several aspects. The first is high efficiency, which can achieve high ventilation effect with low energy consumption by adopting hydrodynamic design. Secondly, safety, which not only has basic over-current and over-voltage protection, but also adds insulation monitoring and fault prediction functions, which can warn potential risks in advance and prolong the service life of equipment by more than 20%.
In the application field, this kind of control panel can be described as a "generalist". In the petrochemical industry, it is used to control the ventilation system and prevent the accumulation of flammable gases; In coal mine, it ensures air circulation and reduces gas concentration; In the fields of pharmacy and food processing, it provides security for the environment containing flammable dust. Especially in industrial fans, the 10-50kW high-voltage brushless control panel can drive the fans to run stably under different working conditions, and adjust the rotating speed to meet the different requirements of workshop ventilation and waste gas treatment.
Strength guarantee of source manufacturers
Speaking of high-voltage explosion-proof brushless fan control panel, we have to mention Shenzhen Hengtai Innovation Electronics Co., Ltd., the original manufacturer. The company was established in March 2012, headquartered in Guangming District, Shenzhen, and also set up a subsidiary in Beijing. After more than ten years of development, it now has a professional team of more than 100 engineers and production employees.
Hengtai's innovative production strength is quite strong, with five advanced Yamaha high-speed patch lines, one wave soldering line, one three-proof automatic coating line and one assembly line. The company uses MES management system to keep 10,000+kinds of electronic components in stock to ensure the production quality and efficiency of the control panel. More importantly, the company passed the ISO9001:2015 international quality system certification and established a perfect quality management system to ensure that every link from raw material procurement to product production meets international standards.
