实施方式Implementation

下面结合附图和具体实施例对本申请作进一步说明:Below in conjunction with accompanying drawing and specific embodiment the application is further described:

本申请实施例公开一种电气火灾监控方法。参照图1,作为一种电气火灾监控方法的一种实施方式,一种电气火灾监控方法包括以下步骤:The embodiment of the present application discloses an electrical fire monitoring method. Referring to Fig. 1, as an embodiment of an electrical fire monitoring method, an electrical fire monitoring method includes the following steps:

步骤S101、实时获取电力设备的电参数信息。Step S101, acquiring electrical parameter information of electric equipment in real time.

电参数信息包括电流信息及电压信息;电流信息包括第一特征电流值。The electrical parameter information includes current information and voltage information; the current information includes a first characteristic current value.

具体地,可以通过连接在电力设备中的电流互感器采集电流信息,通过连接在电力设备中的电压互感器采集电压信息,也可以对电力设备中的电信号进行取样处理后通过示波装置等得到电力设备的电参数信息。第一特征电流值可以是电力设备在一段时间内电流值的平均值,也可以是一段时间内的电流值进行误差处理后得到的平均值,第一特征值表示电力设备当前的电流的大小。Specifically, the current information can be collected through the current transformer connected to the electric equipment, the voltage information can be collected through the voltage transformer connected to the electric equipment, and the electrical signal in the electric equipment can also be sampled and processed by an oscilloscope device, etc. Obtain the electrical parameter information of the electrical equipment. The first characteristic current value may be an average value of the current value of the electric device within a period of time, or an average value obtained after error processing of the current value within a period of time, and the first characteristic value represents the current magnitude of the electric device current.

步骤S102、判断第一特征电流值是否大于预设区间的上阈值;如果是,则在预设第一时长内基于第一特征电流值大于上阈值的时长总和得到第二时长。Step S102 , judging whether the first characteristic current value is greater than the upper threshold of the preset interval; if yes, the second duration is obtained based on the sum of the time durations in which the first characteristic current value is greater than the upper threshold within the preset first duration.

具体地,电力设备中的电流值过大会导致电力设备的电缆温度升高,进而导致电缆绝缘软化,降低电缆的使用寿命。当采集到的第一特征电流值大于预设区间的上阈值,表明电力设备处于过载的异常状态,此时处理器在预设第一时长内统计第一特征电流值大于上阈值的时长总和进而得到第二时长,由于电力设备实时处于波动状态,如果第一特征电流值大于预设区间的上阈值就马上进行提示,容易出现误报的情况。Specifically, an excessive current value in the power equipment will cause the temperature of the cables of the power equipment to rise, which in turn will lead to softening of the cable insulation and reduce the service life of the cables. When the collected first characteristic current value is greater than the upper threshold value of the preset interval, it indicates that the electric equipment is in an abnormal state of overload, and at this time, the processor counts the sum of the time lengths during which the first characteristic current value is greater than the upper threshold value within the preset first time length, and then When the second duration is obtained, since the power equipment is in a fluctuating state in real time, if the first characteristic current value is greater than the upper threshold of the preset interval, a prompt will be issued immediately, which is prone to false alarms.

步骤S103、基于第二时长及第一时长得到过载比值。Step S103. Obtain an overload ratio based on the second duration and the first duration.

步骤S104、判断过载比值是否大于预设比值,如果是,则发送过载信息至外部终端;所述过载信息用于触发所述外部终端生成火灾风险提示信息。Step S104 , judging whether the overload ratio is greater than a preset ratio, and if so, sending overload information to the external terminal; the overload information is used to trigger the external terminal to generate fire risk warning information.

具体地,当过载比值大于预设比值时,表明当前电力设备出现过载的情况,电力设备出现过载容易导致电气设备过热,进而容易导致电气设备发生火灾。此时处理器发送过载信息至外部终端,外部终端可以是中控设备,也可以是外部的智能手机等,用于提醒相应的工作人员。在本申请中,通过对电力设备中的电参数信息进行采集并对采集的电参数信息进行处理,判断电力设备是否处于异常状态,当过载比值大于预设比值时,此时处理器发送过载信息至外部终端,,在外部中端提示电力设备存在一定的火灾风险,便于工作人员更加快速地进行处理,减少电力设备发生火灾的可能性。Specifically, when the overload ratio is greater than the preset ratio, it indicates that the current electrical equipment is overloaded, and the overload of the electrical equipment may easily lead to overheating of the electrical equipment, which in turn may easily cause a fire in the electrical equipment. At this time, the processor sends overload information to the external terminal, which can be a central control device or an external smart phone, etc., to remind corresponding staff. In this application, by collecting the electrical parameter information in the power equipment and processing the collected electrical parameter information, it is judged whether the power equipment is in an abnormal state. When the overload ratio is greater than the preset ratio, the processor sends the overload information at this time To the external terminal, there is a certain fire risk in the external middle end of the electric equipment, which is convenient for the staff to deal with it more quickly and reduces the possibility of fire in the electric equipment.

参照图2,作为一种电气火灾监控方法的其中一种实施方式,电压信息包括电压相位,电流信息还包括电流相位;获取电力设备的电参数信息之后,还包括:Referring to Figure 2, as one of the implementations of an electrical fire monitoring method, the voltage information includes the voltage phase, and the current information also includes the current phase; after obtaining the electrical parameter information of the electrical equipment, it also includes:

步骤S201、基于电压相位及电流相位得到第一功率因数。Step S201. Obtain a first power factor based on the voltage phase and the current phase.

步骤S202、判断第一功率因数是否位于预设功率因素区间;如果否,则发送第一提示信息至外部终端。Step S202, judging whether the first power factor is within a preset power factor interval; if not, sending a first prompt message to an external terminal.

具体地,电压与电流之间的相位差(Φ)的余弦叫做功率因数,用符号cosΦ表示,在数值上,功率因数是有功功率和视在功率的比值,即cosΦ=P/S。电力负荷如电动机、变压器、日光灯及电弧炉等,大多属于电感性负荷,这些电感性的设备在运行过程中不仅需要向电力系统吸收有功功率,还同时吸收无功功率。当用电负载多为感性负载或容性负载时,会消耗大量的无功功率,较大的无功功率会拉低整个电力设备的输电效率,对电力设备的正常运行产生不利的影响。通过电压相位及电流相位得到第一功率因数,判断第一功率因数是否位于预设功率因素区间,当第一功率因数未位于预设功率因素区间,表明电力设备输送了较多的无用功,此时处理器发送第一提示信号至外部终端以提醒相应的工作人员。Specifically, the cosine of the phase difference (Φ) between voltage and current is called the power factor, represented by the symbol cosΦ. In numerical terms, the power factor is the ratio of active power to apparent power, that is, cosΦ=P/S. Electric loads such as motors, transformers, fluorescent lamps, and electric arc furnaces are mostly inductive loads. These inductive devices not only need to absorb active power from the power system during operation, but also absorb reactive power at the same time. When most of the electrical loads are inductive loads or capacitive loads, a large amount of reactive power will be consumed, and large reactive power will lower the transmission efficiency of the entire power equipment and adversely affect the normal operation of the power equipment. Obtain the first power factor through the voltage phase and current phase, and judge whether the first power factor is in the preset power factor range. When the first power factor is not in the preset power factor range, it indicates that the electric equipment has delivered more useless work. The processor sends the first prompt signal to the external terminal to remind corresponding staff.

参照图3,作为一种电气火灾监控方法的其中一种实施方式,在判定第一功率因数未位于预设功率因素区间之后,还包括:Referring to Figure 3, as one of the implementations of the electrical fire monitoring method, after determining that the first power factor is not within the preset power factor range, it further includes:

步骤S301、发送第一控制信号至无功补偿电容器模块;第一控制信号用于触发无功补偿电容器模块的预设个数的电容器工作;无功补偿电容器模块并联于电力设备的输电线路;无功补偿电容器模块包括若干相互并联的电容器;Step S301, sending the first control signal to the reactive power compensation capacitor module; the first control signal is used to trigger the operation of the preset number of capacitors in the reactive power compensation capacitor module; the reactive power compensation capacitor module is connected in parallel to the transmission line of the power equipment; The power compensation capacitor module includes several capacitors connected in parallel;

步骤S302、在无功补偿电容器模块运行预设时长后,基于当前的电流相位及电压相位得到第二功率因素;Step S302, after the reactive power compensation capacitor module runs for a preset period of time, obtain a second power factor based on the current current phase and voltage phase;

步骤S303、判断第二功率因素是否位于预设功率因素区间;如果是,执行步骤S304;如果否,执行步骤S305;Step S303, judging whether the second power factor is within the preset power factor interval; if yes, execute step S304; if not, execute step S305;

步骤S304、发送第二提示信息至外部终端;Step S304, sending the second prompt message to the external terminal;

步骤S305、发送第二控制信号至无功补偿电容器模块;第二控制信号用于触发无功补偿电容器模块逐个增加并联至电力设备的输电线路的电容器的数量,重复步骤S302~S303。Step S305, sending a second control signal to the reactive power compensation capacitor module; the second control signal is used to trigger the reactive power compensation capacitor module to increase the number of capacitors connected in parallel to the transmission line of the electric equipment one by one, and repeat steps S302-S303.

具体地,无功补偿电容器模块包括若干相互并联的电容器,无功补偿电容器模块并联于电力设备。在判定第一功率因数未位于预设功率因素区间之后,处理器发送第一控制信号至无功补偿电容器模块。无功补偿电容器模块并联且工作于电力设备时,可以提供补偿感性负荷所消耗的无功功率,减少了电力设备向感性负荷提供的无功功率。并联到电力设备的无功补偿电容器会对谐波有放大作用,谐波电流会使得变压器的局部过热,因此在本申请中,逐个增加并联至电力设备的输电线路且工作的电容器的数量。由于减少了无功功率在电力设备中的流动,进而降低了电能损耗,提高了电能的传输效率。Specifically, the reactive power compensation capacitor module includes several capacitors connected in parallel, and the reactive power compensation capacitor module is connected in parallel with the electric equipment. After determining that the first power factor is not within the preset power factor range, the processor sends a first control signal to the reactive power compensation capacitor module. When the reactive power compensation capacitor modules are connected in parallel and work on electric equipment, they can provide compensation for reactive power consumed by inductive loads, reducing the reactive power provided by electric equipment to inductive loads. The reactive power compensation capacitors connected in parallel to the power equipment will amplify the harmonics, and the harmonic current will cause local overheating of the transformer. Therefore, in this application, the number of capacitors connected in parallel to the transmission lines of the power equipment and working is increased one by one. Since the flow of reactive power in the electric equipment is reduced, the loss of electric energy is reduced, and the transmission efficiency of electric energy is improved.

参照图4,作为一种电气火灾监控方法的其中一种实施方式,若判定第一功率因数没有位于预设功率因素区间,该方法还包括:Referring to Figure 4, as one of the implementations of an electrical fire monitoring method, if it is determined that the first power factor is not within the preset power factor range, the method further includes:

步骤S401、获取电力设备的若干个检测点的温度得到若干检测温度值;Step S401, obtaining the temperatures of several detection points of the electric equipment to obtain several detection temperature values;

步骤S403、判断温度特征值是否大于预设值;如果是,则发送第三提示信息至外部终端。Step S403, judging whether the temperature characteristic value is greater than a preset value; if yes, sending a third prompt message to the external terminal.

具体地,并联到电力设备的无功补偿电容器会对谐波有放大作用,谐波电流会使得变压器的局部过热。若干个检测点是预先设置的,可以通过设置于检测点的温度传感器得到检测点的温度值。处理器与温度传感器相通信,温度传感器检测对应检测点的温度后将温度数据发送至处理器,处理器基于获取的温度数据得到温度特征值,温度特征值可以是所有温度数据进行求和取平均值得到的,也可以是所有的温度数据进行误差处理后再求和取平均值后得到的,当判定温度特征值大于预设值是,处理器发送第三提示信息值外部终端以提示相对应的工作人员。Specifically, the reactive power compensation capacitor connected in parallel to the power equipment will amplify the harmonics, and the harmonic currents will cause local overheating of the transformer. Several detection points are pre-set, and the temperature value of the detection point can be obtained through the temperature sensor set at the detection point. The processor communicates with the temperature sensor. The temperature sensor detects the temperature of the corresponding detection point and sends the temperature data to the processor. The processor obtains the temperature characteristic value based on the acquired temperature data. The temperature characteristic value can be summed and averaged for all temperature data. It can also be obtained by summing and averaging all the temperature data after error processing. When it is determined that the temperature characteristic value is greater than the preset value, the processor sends the third prompt information value to the external terminal to prompt the corresponding staff of.

参照图5,作为一种电气火灾监控方法的其中一种实施方式,在判定温度特征值大于预设之后,还包括:Referring to Figure 5, as one of the implementations of the electrical fire monitoring method, after determining that the temperature characteristic value is greater than the preset, it also includes:

步骤S501、重新采集电力设备的电参数信息;Step S501, re-collect the electrical parameter information of the electric equipment;

步骤S502、基于电参数信息中的电压信息得到电压中的谐波分量;以及,Step S502, obtaining the harmonic component in the voltage based on the voltage information in the electrical parameter information; and,

步骤S503、判断电压中的谐波分量是否大于预设幅值;如果是,则发送第三控制信号至电力设备的整流器件,第三控制信号用于触发整流器件增加整流相数或者增加整流的脉动数。Step S503, determine whether the harmonic component in the voltage is greater than the preset amplitude; if so, send a third control signal to the rectifier device of the power equipment, and the third control signal is used to trigger the rectifier device to increase the number of rectification phases or increase the rectification phase Pulse count.

具体地,处理器重新采集电力设备的电参数信息并基于电参数信息中的电压信息得到电压中的谐波分量,当判定谐波分量大于预设幅值,表明发热的原因极大可能是由于谐波导致的,此时处理器发送第三控制信号至电力设备的整流器件,增加整流相数或者增加整流的脉动数,从而有效地抑制频率稍低的谐波;当整流相数增加至一倍时,谐波电流将下降四倍左右,大大降低了谐波的数量,进而能够降低变压器的温度,有利于维持电力设备的正常运行。Specifically, the processor re-collects the electrical parameter information of the power equipment and obtains the harmonic component in the voltage based on the voltage information in the electrical parameter information. When it is determined that the harmonic component is greater than the preset amplitude, it indicates that the cause of heating is most likely due to caused by harmonics, at this time the processor sends a third control signal to the rectifier device of the power equipment to increase the number of rectification phases or increase the number of pulsations of rectification, thereby effectively suppressing the harmonics with a slightly lower frequency; when the number of rectification phases increases to one times, the harmonic current will drop by about four times, greatly reducing the number of harmonics, which in turn can reduce the temperature of the transformer, which is conducive to maintaining the normal operation of power equipment.
