Abstract
Disclosed is a high voltage frequency conversion apparatus with a wireless remote control function, comprising a high voltage frequency converter, and a remote control device matched to the high voltage frequency converter, wherein the high voltage frequency converter is provided with a first central processor; the first central processor is connected with a wireless signal receiving module; the remote control device is provided with a second central processor; and the second central processor is connected with a control module and a wireless signal emission module that is wirelessly communicated with the wireless signal receiving module. As a wireless remote control device is added to the high voltage frequency converter, the remote control over the high voltage frequency converter can be realized. When a bypass is needed to be switched or something is wrong with the device, the frequency converter can be directly controlled in a remote manner to reach the secure state, thereby providing convenience for users and ensuring the personnel safety.
Description
Technical field
The utility model relates to a kind of converter plant, specifically high voltage frequency converter.
Background technology
Converter plant VFD (Variable-frequency Drive) is application of frequency conversion technology and microelectric technique, and the frequency through changing the machine operation power supply and the mode of amplitude are controlled the Electric Drive element of alternating current motor.Converter plant is integrated high-voltage high-power transistor technology and electron controls technology are used widely.The effect of converter plant is frequency and the amplitude that changes the alternating current machine power supply, thereby changes the cycle of its moving magnetic field, reaches the purpose of level and smooth control motor speed.The appearance of converter plant; Make complicated speed regulating control oversimplify, with converter plant+mouse cage AC formula induction motor combination replacement most ofly originally can only dwindle volume with the work of direct current machine completion; Reduced maintenance rate, made drive technology develop into the new stage.Present high voltage frequency converter does not generally have the wireless remote control function, must directly contact with frequency converter when needing to regulate frequency converter, when frequency converter is out of order, goes out danger so easily.
The utility model content
For overcoming the deficiency of prior art, the utility model provides a kind of can realize Long-distance Control, guarantees the high voltage frequency converter with wireless remote control function of personal security.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is a kind of high voltage frequency converter with wireless remote control function, comprises high voltage converter and the remote control suitable with it; Be provided with first central processing unit in the said high voltage converter, on first central processing unit, be connected to the wireless signal receiver module; Be provided with second central processing unit in the said remote control, on second central processing unit, be connected to control module and with the wireless signal transmitting module of wireless signal receiver module wireless telecommunications.
Beneficial effect: the utility model is owing to set up wireless remote control device on high voltage converter; Therefore can realize remote control to high voltage converter; When needs switch bypass or equipment and break down; Directly the far distance controlled frequency converter reaches safe condition, makes things convenient for the user and guarantees personal security.
