The voltage instantaneous fluctuation prevention protector comprises a charging / discharging circuit, wherein the charging / discharging circuit is connected between a direct current power supply of the elasticizer and a load and comprises a current-limiting resistor R1, a charging / discharging capacitor C1 and a discharging diode V1, one end of the current-limiting resistor R1 and the output end of the discharging diode V1 are connected with the positive electrode of the direct current power supply of the elasticizer, the other end of the current-limiting resistor R1 and the input end of the discharging diode V1 are connected with the one end of the charging / discharging capacitor C1, and the other end of the charging / discharging capacitor C1 is grounded. The voltage instantaneous fluctuation prevention protector for the elasticizer has the advantages of simple structure, very low cost and subsequent maintenance cost and very strong practicability.

Description

technical field [0001] The invention relates to an electrical control technology for preventing voltage fluctuations of a texturing machine, in particular to a protector for a texturing machine against instantaneous voltage fluctuations. Background technique [0002] Texturing machine is a kind of textile machine that can process polyester, polypropylene and other untwisted yarns into elastic yarns with medium and low elastic properties through false twist deformation. [0003] However, due to various reasons such as thunderstorms in summer and power user line failures, the grid voltage has an average of 5 to 7 voltage fluctuations per year, resulting in an instantaneous drop or interruption of the supply voltage. This fluctuation generally lasts for 50 Between milliseconds and 500 milliseconds. When voltage fluctuations occur, it is likely that the texturing machine will be powered off and stopped. After parking, the operator has to doff the bobbin and start the new head,...

AI Technical Summary

Problems solved by technology

After parking, the operator has to doff the bobbin and start the new head, which increases the labor load and reduces the utilization rate of the machine, resulting in a decrease in the full volume rate, a corresponding increase in the amount of waste silk and paper tube consumption, and a corresponding increase in the consumption of compressed air. Increase

Therefore, every time the texturing machine is stopped, the loss caused by each machine exceeds 10,000 yuan (depending on the product and the loss)

[0004] In order to solve the above problems, the current feasible solution is: add UPS (Uninterruptible Power Supply, uninterruptible power supply) to the power supply and control circuit of the texturing machine. However, due to the high price of UPS, the transformation cost of the whole equipment is too large and The structure is more complicated, and once the UPS fails, its maintenance cost is also quite high
