EXAMPLE III
In order to solve the above technical problems in the prior art, an embodiment of the present invention provides a control method for preventing an indicator light from being turned on falsely based on a second embodiment, where in the control circuit for preventing an indicator light from being turned on falsely, the control module includes an intermediate relay, and the switch module is a normally open contact.
Referring to fig. 4, the control circuit for preventing the false lighting of the indicator lamp includes: (1) the intermediate relay KA, (2) the absorption capacitor C and (3) the indicator lamp L. The indicating lamp L is connected with the normally open contact KA of the intermediate relay KA in series, the normally open contact is controlled to be switched on and off by the coil of the intermediate relay KA, and finally the absorption capacitor C is added in a loop and connected with the indicating lamp L of the normally open contact KA in series in parallel for absorbing interference current and voltage transmitted by the indicating lamp L and preventing a control circuit behind the indicating lamp L from being influenced by interference.
Referring to fig. 5, the control method for preventing the indicator lamp from being falsely turned on of the present embodiment includes the steps of:
the control method can enable the indicator light of the frequency converter to effectively resist interference current and voltage, and the control method utilizes the on-off control principle of the intermediate relay to isolate the indicator light from the interference current and the interference voltage, and then absorbs the interference current and the interference voltage by the absorption capacitor. The detailed implementation mode is as follows:
firstly, if a small current and a low voltage generated by interference are introduced into an indicator light loop, the current and the voltage generated by the interference are very small and cannot reach the capability of enabling an intermediate relay to act, so that the intermediate relay KA cannot be actuated to act at the moment, a normally open contact cannot be closed, an indicator light L cannot be electrified and does not flicker, and finally the interference current and the interference voltage are absorbed by a C absorption capacitor to prevent a following control circuit from being influenced by the interference;
secondly, if the indicator light needs to work normally, then the power and signal controller S1 will send out a signal, the power supply of the indicator light will be switched on, and will provide a rated voltage of 24V dc, first the coil of KA relay will start to act after having 24V ac voltage passed through, so the KA normally open contact controlled by KA relay will be closed, so the indicator light L can only be switched on 24V rated voltage, and can work normally and light. When the indicating lamp L does not need to work, the power supply is disconnected, firstly, the coil of the KA intermediate relay loses power, then the KA normally open contact is reset to be in an open state from a closed state, at the moment, the indicating lamp L is disconnected from the 24V power supply, and the indicating lamp L stops working.
When the control method and the control circuit for preventing the indicator light from being falsely lighted according to the embodiment are applied to a magnetic suspension frequency converter of a large-scale central air conditioner, specifically, a high-power frequency converter of a magnetic suspension frequency conversion centrifugal water-cooling unit, referring to fig. 6, a circuit of the high-power frequency converter includes a 380V three-phase alternating current power supply, a transformer T, a power supply and signal controller S1, a KA intermediate relay S2, an indicator light L, a normally open contact KA, an absorption capacitor C, a driving and control circuit S3, a rectification and inversion IGBT module S4 and a magnetic suspension compressor M.
The control module and the power module in the first embodiment are embodied as the power supply and signal controller S1 and the KA intermediate relay in this embodiment, and the switch module in the first embodiment is the normally open contact KA in this embodiment.
The working principle of the high-power frequency converter is as follows:
the 380V three-phase alternating current of the industrial power is introduced into the magnetic suspension high-power frequency converter, and is supplied to the magnetic suspension compressor M to work after being rectified and inverted by the frequency converter IGBT module S4. The 380V alternating current is led out from the frequency converter, is converted into 220V alternating current by voltage reduction through a transformer T, and then is supplied to a power supply and signal controller S1. After passing through the controller S1, a dc power of, for example, 24V and related control signals may be output. The 24V dc power is mainly used to power the frequency converter related indicator lamp L and the driving and control circuit S3.
24V direct current is connected to a KA intermediate relay S2, and then connected with a related indicator light L of a frequency converter, a normally open contact KA is connected with the indicator light L in series, and the action of the normally open contact KA is controlled by the KA intermediate relay S2. The absorption capacitor C is used for absorbing the conducted interference current and voltage to prevent the following driving and control circuit S3 from being affected by interference. The driving and controlling circuit S3 controls the rectification and inversion IGBT module to work so as to drive the magnetic suspension compressor M to work.
In the control circuit for preventing the indicator light from being falsely lighted in the embodiment, the power-on condition of the indicator light is controlled by utilizing the working principle that the relay contact is controlled to be switched on and off by the intermediate relay, then, the external absorption capacitor absorbs the interference current and the voltage flowing through the loop of the indicator light, and the interference of an interference source to the indicator light is further prevented.
In the control circuit for preventing the indicator light from being falsely lighted of the embodiment, when the frequency converter is electrified and started, large current exists in the whole frequency converter, small current exists between loops of the frequency converter due to high voltage, low voltage and the like are generated, so that an interference source enters the loops of the indicator light, the problem that the indicator light flickers and misreports is caused, the indicator light of the frequency converter can achieve the capacity of resisting interference by using the principle of an intermediate relay and measures such as an additional absorption capacitor and the like, the problems that the indicator light flickers and misreports and the like are caused by interference of the indicator light of the high-power frequency converter are effectively solved, the normal operation of the high-power frequency converter is ensured, the design scheme is low in cost, and the effect is obvious.
It should be noted that the control method for preventing the indicator light from being falsely turned on can be applied not only to the high-power frequency converter shown in this embodiment, but also to the indicator light of the high-power equipment such as a starting cabinet, an electric cabinet, a load box, and the like.
