The smelter will cause a lot of high-temperature soot and soot in the whole process of the steel smelting plant, which will cause environmental pollution to the natural environment. A very small part of this kind of soot is scattered in the production workshop, and most of them overflow from the top of the production workshop, and the dust suspended matter falls into the surrounding area of the industrial area, which seriously endangers everyone's work life. With the development of economic development and technical development and the improvement of everyone's awareness of protection, improve the natural environment of the surrounding industrial areas of the production workshop, and set dust removal equipment is indispensable.
The intelligent smelter dedusting equipment contains one ash removal and another ash removal. One time, the ash removal is selected by the force to remove ash, and the coarse particulate matter is removed. Once the ash is removed, the ash removal is carried out again. The dust removal equipment is related to the advantages and disadvantages of the surrounding environment.
In the dust removal equipment again, the dust collector is a very important machine equipment, and the high-voltage motor is driven by the dust collector. The high-voltage solid-state soft start cabinet is started immediately, the starting current is very large, and the impact high-voltage line immediately jeopardizes all the normal work of the piezoelectric device under the same power grid. In some smelters with low power grid capacity, when the high-voltage motor is started, It is imperative to shut down other electrical equipment on the power grid, seriously jeopardizing the manufacturing theme activities of the smelter. The other immediate start causes strong mechanical stress on the mechanical structure, reduces the service life of the centrifugal fan and the motor, and increases the compressive strength and cost of maintenance of the dust removal equipment.
In order to reduce the amount of motor starting current and prevent the adverse effect of excessive starting current, it is necessary to use a soft start method to start the high voltage motor. Among all the soft start methods, the thyristor hypotensive SSD soft start combined with electronic information technology and contemporary power electronic technology has unique advantages. The result is at the leading level among a variety of soft start methods.
Features of high-pressure solid-state soft start cabinet:
The high-voltage solid-state soft start cabinet selects the internationally excellent optical fiber technology between the main control loop and the automatic control system. The control board also selects the dual CPU system software according to the DSP operation and the single-chip design management method. The DSP is 16 bits. Large digital signal processor, command production pipeline actual operation, fast response time, and implement key operations. The MCU design is consistent with the main parameter setting, text display information and data communication implementation management method, and high efficiency.
Thin film panel, Chinese display, visualized industrial touch screen, easy to use. According to the RS485 or Profibus standard interface, communicate with the host computer to maintain remote control, telemetry or multi-level linkage.
The system software has the following functions: 1 On-site button activation. 2 The keyboard button is activated. 3 The host computer remote control starts. 4 composition starts.
Depending on the motor load, the high-pressure solid-state soft starter can be set to a different method of operation.
1) Steep slope working voltage control. Given the necessary raw output operating voltage and soft start time, the operating voltage rises linearly with time during the start of the motor until the motor exceeds the rated speed ratio. The original working voltage is 20% to 80% of the full working voltage, the size can be adjusted by the load characteristics, and the original working voltage of the heavy load is high. The operating method of the steep slope working voltage is simple, and the load can have different steep slopes, which can be mastered.
