Monitoring device for current-voltage-temperature and humidity of high frequency direct current switching power supply

Abstract

The invention provides a monitoring device for the current-voltage-temperature and humidity of a high frequency direct current switching power supply, and belongs to the technical field of electricians. The device comprises a transmitting apparatus and a receiving apparatus. The transmitting apparatus is used for collecting, controlling, and sending the output current, voltage, and temperature andhumidity value of a high frequency direct current switching power supply cabinet, and displaying the collected values. The receiving apparatus is used for receiving and displaying the collected values of the transmitting apparatus, sending a control signal to the transmitting apparatus, collecting the current, the voltage, and the temperature and humidity value, and displaying the values collected by the receiving apparatus. A 2.4G frequency band or an RS485 module is adopted between the transmitting apparatus and the receiving apparatus for data transmission. The monitoring device has the advantages of being simple to install, stable in wireless transmission data, capable of remotely controlling and the like.

Description

technical field [0001] The invention belongs to the technical field of electric engineering, and in particular relates to a current-voltage-temperature-humidity monitoring device of a high-frequency DC switching power supply. Background technique [0002] In the process of rare earth electrolysis, the stability of current and voltage is the main factor affecting the effect of electrolysis. Stable and accurate current and voltage can guarantee the stability of product quality to a certain extent. High-frequency DC switching power supply may experience abnormal temperature rise during long-term operation, especially when the input three-phase current is unbalanced, the temperature rise is particularly serious. Temperature rise is the main factor affecting the instability of the output current and voltage of the high-frequency DC switching power supply. In the equipment room of the rare earth electrolytic power cabinet, most of them use semi-closed display power cabinets, and t...

Problems solved by technology

Temperature rise is the main factor affecting the instability of the output current and voltage of the high-frequency DC switching power supply. In the equipment room of the rare earth electrolytic power cabinet, most of them use semi-closed display power cabinets, and the heat dissipation effect is not good. If the temperature of the corresponding power cabinet is not correct , current and voltage can be monitored in a timely and effective manner. High temperature will cause the power cabinet to fail to work normally. At the same time, the stability of the output current and voltage cannot be monitored in time. In addition, the ambient humidity of the high-frequency DC switching power supply will affect the reliability and reliability of the original equipment. Therefore, it should be ensured that the humidity is maintained within the allowable range for the normal operation of the equipment for a long time

[0003] Most of the existing technologies have the following disadvantages: the collection signal is single; the monitored data cannot be remotely controlled; it is not suitable for high-frequency equipment rooms, and it is susceptible to electromagnetic field interference, resulting in data packet loss; the transmission distance is short and the data is unstable; Acquisition of high current and low voltage
