Definitions
- This invention relates to an electronic ballast, and more particularly to a method for time-division start of an electronic ballast and a time-delayed electronic ballast in order to overcome a short-time voltage drop of a line when multiple electronic ballasts are operated in parallel.
- ballast is an electronic control device that converts a direct current or low frequency alternating current voltage into a frequency alternating current voltage and drives a light source such as a low pressure gas discharge lamp or a tungsten halogen lamp.
- a light source such as a low pressure gas discharge lamp or a tungsten halogen lamp.
- Electronic ballasts are widely used due to their low energy consumption, high efficiency, light efficiency, light weight, and power factor. In particular, the advantages of high-power electronic ballasts in applications are more obvious. Therefore, in the case of vegetable cultivation, street lamps, etc., multiple units in parallel are used in series. In the application, each electronic ballast starts working simultaneously when the switch is uniformly energized to the line. Due to the line impedance of the power grid, multiple large currents simultaneously start to cause the line voltage to drop.
- the electronic ballast is a constant power load. In order to maintain the power at startup, the electronic ballast can only increase the input current by a multiple, and the input current increases. The further increase caused the grid voltage to drop, forming a vicious circle.
- the invention provides a control method for delaying start of an electronic ballast and an extension method for solving the problem that the electronic ballast is randomly damaged due to the simultaneous start of the multi-electronic ballast and the lamp tube in parallel, causing the instantaneous voltage drop of the grid voltage and the random damage of the electronic ballast. When starting the electronic ballast.
- the technical scheme of the utility model is: a control method for time-division start of an electronic ballast, wherein after the electronic ballast is powered, the electronic ballast is delayed to start, and the electronic ballast delay is obtained.
- the delay time of the startup includes the following steps:
- Step A detecting the real-time temperature of the electronic ballast
- Step B normalizing the real-time temperature value of the electronic ballast at this time;
- Step C obtaining the real-time temperature value in the mapping relationship between each value and the delay time in the previously determined normalization interval The delay time after mapping.
- step B When the real-time temperature is normalized in step B, the following steps are included:
- Step B01 amplifying the real-time temperature value
- Step B02 intercepting the low-order portion of the amplified real-time temperature value.
- step B01 the real-time temperature value is amplified to at least one hundred digits, and the decimal point portion is discarded; the step B02 is intercepted and amplified.
- the single digit and the tens digit of the subsequent real-time temperature value further includes step B03, dividing the number of results in step B02 by 2, and then "rounding off" to obtain the normalized number.
- the relationship between each value and the delay time in the predetermined normalization interval is: normalized number is 0 to 49, mapped to 0 ⁇ The delay time is from 0.1 to 5. 0 seconds.
- the invention also provides a delay-activated electronic ballast, comprising an electronic ballast body and a delay switch, wherein the delay switch is disposed at the current input end of the electronic ballast body;
- the delay switch is a digital delay switch that automatically sets a delay time, and includes a temperature sensor that detects an external ambient temperature of the electronic ballast, and an A/D converter that performs analog/digital conversion on the signal output by the temperature sensor,
- the digital output processor of the A/D converter outputs data, and the processing result output by the digital processor is connected to the digital input end of the digital delay switch.
- the delay device using the delay time set by the random number corresponding to different ambient temperatures is added to the ballast, the plurality of ballasts connected in the circuit are Under the control of the same control switch, starting at different time points through different delay times, the current impact on the power grid is significantly reduced, and the voltage drop is reduced, thereby solving the instantaneous voltage drop of the grid voltage caused by the simultaneous start of multiple machines.
- Technical problems with random damage to electronic ballasts since the delay device using the delay time set by the random number corresponding to different ambient temperatures is added to the ballast, the plurality of ballasts connected in the circuit are Under the control of the same control switch, starting at different time points through different delay times, the current impact on the power grid is significantly reduced, and the voltage drop is reduced, thereby solving the instantaneous voltage drop of the grid voltage caused by the simultaneous start of multiple machines.
- 1 is a flow chart of the acquisition delay time of the present invention.
- FIG. 2 is a block diagram showing the structure of a single time delay electronic ballast of the present invention.
- the embodiment i is an electronic ballast that can be used in parallel by a plurality of electronic ballasts.
- the difference from the ordinary electronic ballast is that it is connected to the mains.
- a digital delay switch is added, and the delay time is separately obtained by the method of the present invention.
- FIG. 2 a single electronic ballast with a delay switch in this embodiment is shown in the figure.
- Example of a delayed start electronic ballast including an electronic ballast body and delay
- the delay switch is set at the mains current input end of the electronic ballast body
- the delay switch is a digital delay switch that automatically sets the delay time, including a temperature sensor for detecting the external ambient temperature of the electronic ballast, and the temperature sensor output
- the signal is subjected to analog/digital conversion A/D converter, the digital processor for data processing of the digital output of the A/D converter, and the processing result of the digital processor output is connected to the digital input terminal of the digital delay switch.
- the digital processor has the following steps to complete the setting of the random delay time: as shown in Figure 1.
- Step A detecting the real-time temperature of the electronic ballast
- Step B normalizing the real-time temperature value of the electronic ballast at this time; amplifying the real-time temperature value to at least one hundred digits, and discarding the decimal point portion; intercepting the single digit of the amplified real-time temperature value and Ten digits;
- Step C In the mapping relationship between each value and the delay time in the predetermined normalization interval, obtain the delay time mapped after the normalized temperature value is normalized.
- each value and the delay time in the previously determined normalization interval is as follows:
- the normalized number is 0 to 49, and the delay time is 0.1 to 5. 0 seconds.
- a control method for time-divisionally starting an electronic ballast is adopted, and the electronic ballast in the method includes a variable generation and a program calculation portion.
- Variable generation includes temperature detection and A/D conversion modules. Temperature detection detects small differences in temperature of different electronic ballasts, and thus obtains different variable coefficients of different machines.
- the A/D conversion module quantizes the analog part, and the program calculation includes decimal calculation and time setting.
- the decimal calculation section is used to amplify the low-order portion of the quantized data to make the random time difference more obvious, while limiting the case where the coefficient of the variable is very large.
- the time setting section takes the random coefficient as the time base from power-on to startup. The startup work is performed when the arrival time is set.
- the electronic ballast is started in time sharing as shown in Fig. 2, including the variable generation and program calculation sections.
- Variable generation includes temperature detection and A/D conversion modules. The temperature is detected by the external ambient temperature signal, and the temperature signals at different positions are slightly different.
- the digital conversion is digitally quantized by the AD conversion module to facilitate signal processing.
- the program calculation section includes decimal calculation and time setting and execution.
- the AD conversion module outputs the fraction that ingests the low position during the conversion process in decimal calculation, and is mainly used to amplify the changed portion while limiting the variable value to a certain range. Since the change time is in seconds, the variable value is limited to 50 steps to achieve 0.1 seconds.
- the time setting and execution load the variable value of the decimal calculation output into the time counter, and different variable values implement different startup times.
- the above method can also not perform the calculation of divide by 2, so the normalized number is 0-99, if the first number corresponds to the number plus 1 and then divided by 20 to obtain the number of seconds, the same.
