As shown in fig. 1, the application provides a method for evaluating the fire resistance of a ceramic matrix composite bus duct, wherein the method is applied to a system for evaluating the fire resistance of the ceramic matrix composite bus duct, and the method specifically includes the following steps:
step S100: collecting first historical use data of a first bus duct, and screening the first historical use data to obtain first target use data;
specifically, the first bus duct is a ceramic-based composite material fireproof bus duct specially used for a power supply of fire-fighting equipment, the bus duct is good in heat resistance and heat insulation, and a shell is made of a high-temperature-resistant fireproof material and an insulating material. Preferably, a fireproof material with high temperature resistance of more than or equal to 1100 ℃ and an insulating material with high temperature resistance of more than or equal to 300 ℃ are adopted. The first historical use data is the use data generated by the first bus duct in use, and comprises a use environment, a load, a highest bearing temperature, an average heated temperature, a heated temperature in failure, a use duration, a failure reason, the integrity of a line after a fire, a maintenance record and the like. The step of screening the first historical use data refers to screening the end-of-life cases with poor fire resistance as failure reasons from the first historical use data to obtain historical records of all the cases, namely the first target use data. By finding out historical data of bus duct failure caused by poor fire resistance from historical service conditions, the technical effects of providing data base and data support for subsequent preliminary analysis and estimation of fire resistance of the bus duct based on the historical service conditions of the bus duct and providing reference data for subsequent fire resistance evaluation of the bus duct are achieved.
Step S200: comparing the first target usage data to obtain a first fire resistance pre-evaluation, wherein the first fire resistance pre-evaluation is a preliminary evaluation of fire resistance of the first busway;
specifically, the comparison of the first target usage data refers to obtaining a temperature condition when the first target fails, a correlation degree between a failure cause and temperature, a fire resistance time and the like by performing comparative analysis on historical usage of the first bus duct, and performing the first fire resistance pre-evaluation on the first bus duct according to the obtained information. The first fire-resistant pre-evaluation is a preliminary evaluation obtained based on historical use conditions of fire resistance of the first bus duct, including historical data such as the highest fire-resistant temperature and the duration of fire resistance. Preferably, the temperature and the working time at the corresponding temperature when the bus duct fails in each case are respectively extracted based on a plurality of historical bus duct failure cases caused by insufficient fire resistance, and the record with the highest temperature and the longest working time is taken as the initial evaluation of the bus duct. Through right first bus duct carries out fire-resistant preliminary evaluation, can realize making the foreshadowing for confirming the follow-up temperature range that carries out the temperature test, reduces the detection operation, reduces the technological effect of detection cost.
Illustratively, the first fire resistance pre-rating may be divided into four grades based on the fire resistance time at which the first target fails, with a fire resistance time of 60 minutes being rated as the first grade, a fire resistance time of 90 minutes being rated as the second grade, a fire resistance time of 120 minutes being rated as the third grade, and a fire resistance time of 180 minutes being rated as the fourth grade.
Step S300: collecting first basic information of the first bus duct, wherein the first basic information comprises a first fire-resistant requirement;
specifically, the first basic information of the first bus duct includes: production batch, production process, production model, ceramic proportion of the composite material, composite mode, service life in fire environment, temperature capable of bearing fire and the like. The first fire demand refers to a fire resistance temperature value, which refers to a maximum temperature that can be tolerated in a fire environment, and a fire resistance time duration, which refers to a maximum time that line integrity can be maintained in a fire environment. Based on the first basic information, the technical effect of providing basic data for subsequent fire-resistant treatment on the first bus duct is achieved.
Step S400: determining a first treatment condition based on the first refractory requirement and the first refractory pre-evaluation, wherein the first treatment condition comprises a first treatment temperature threshold;
specifically, based on obtaining the first fire resistance requirement and the first fire resistance pre-evaluation, a first processing condition for a fire resistance test measuring the first busway can be determined. The first treatment condition refers to specific test conditions in a fire resistance test of the first bus duct, and comprises test temperature conditions, test duration and the like. The first treatment temperature threshold refers to a treatment temperature interval for the first bus duct according to the first fire-resistant requirement and the first fire-resistant pre-evaluation, namely a temperature range in a fire-resistant performance test. Wherein the first refractory requirement is taken as the lowest test temperature, i.e. the lower limit of the first treatment temperature threshold, and the highest temperature evaluation in the first refractory pre-evaluation is taken as the highest test temperature, i.e. the upper limit of the first treatment temperature threshold. Therefore, the temperature range of the test can be accurately determined, the test amount is effectively reduced, the test time is shortened, the test efficiency is improved, and the technical effect of the fire resistance evaluation efficiency of the first bus duct is improved.
Step S500: generating a first processing scheme by using a control variable method according to the first processing temperature threshold, wherein the first processing scheme comprises a first constant temperature scheme and a first variable temperature scheme;
specifically, the first treatment recipe is generated by a controlled variable method based on the obtained trial temperature range. Because there are many variables characterizing the first bus duct, it is necessary to analyze and evaluate factors mainly affecting the fire resistance performance of the first bus duct by a controlled variable method. The first processing scheme refers to that the first bus duct is subjected to test processing by controlling other variables, such as wind speed, air pressure, humidity and the like, and only changing the variable of temperature. The first constant temperature scheme is that the test temperature is adjusted to be a fixed value, and different fixed temperatures are adopted for testing the first bus duct for multiple times. The first temperature changing scheme is that a temperature interval is set, and the first bus duct is tested by carrying out random temperature change in the temperature interval. Therefore, the fire resistance of the first bus duct can be further tested by controlling the temperature parameter, and the technical effect of improving the accuracy of the test of the fire resistance of the bus duct is achieved.
Step S600: carrying out constant temperature treatment on the first bus duct according to the first constant temperature scheme to obtain a first treatment result, and carrying out variable temperature treatment on the first bus duct according to the first variable temperature scheme to obtain a second treatment result;
specifically, the first processing result is that after the first bus duct is processed at a constant temperature, the condition of the bus duct includes: whether the internal circuit is complete or invalid, whether the internal circuit is invalid or invalid after a long time, whether the internal circuit can work by electrifying, and the like. The second processing result is that after the first bus duct is subjected to temperature change processing, the conditions of the bus duct include: whether the internal circuit is complete or invalid, whether the internal circuit is invalid or invalid after a long time, whether the internal circuit can work by electrifying, and the like. Therefore, the technical effect of providing basic analysis data for subsequent failure check and analysis is achieved.
Step S700: sequentially carrying out failure check and analysis on the first processing result and the second processing result to respectively obtain a first analysis result and a second analysis result;
specifically, the sequentially performing failure check and analysis on the first processing result and the second processing result refers to checking relevant parameters characterizing the performance of the first busway in the processing results, and preferably, the relevant parameters may be: appearance parameters of the bus duct, temperature rise condition parameters of a bus duct shell, temperature rise condition parameters of the surface of an insulating piece in the duct and the like. And whether the first bus duct fails or not is judged by checking whether the conductive function of the first bus duct is intact or not and whether the circuit integrity can be kept or not in a flame state within a certain time. The first analysis result is the highest temperature that the bus duct can bear under the constant temperature state, and the longest operating time that can persist under each high temperature. And the second analysis result is the highest temperature change interval which can be borne by the bus duct in the temperature change state and the longest working time which can be maintained in each temperature change interval. This achieves the technical effect of providing reliable test data for later development of a fire resistance evaluation of the first bus duct.
Step S800: and generating a first fire resistance evaluation of the first bus duct according to the first analysis result and the second analysis result.
Specifically, the information related to the fire resistance of the first bus duct in the first analysis result and the second analysis result, optionally, such as fire resistance time, fire resistance temperature, etc., is analyzed to analyze the fire resistance of the first bus duct under the conditions of temperature changing and constant temperature. The refractory performance of the ceramic matrix composite bus duct can be evaluated stably and comprehensively, the operability is high, the detection cost is reduced, the intelligent degree of the detection of the refractory performance is improved, and therefore the technical effects of the detection efficiency and the accuracy are improved.
Further, as shown in fig. 2, in the generating the first processing solution by using a control variable method according to the first processing temperature threshold, step S500 in this embodiment of the present application further includes:
step S510: performing gradient division on the first processing temperature threshold to respectively obtain first division results, wherein the first division results comprise a plurality of temperature intervals;
step S520: sequentially calculating each temperature interval in the plurality of temperature intervals to respectively obtain a plurality of average temperatures, wherein the average temperatures are in one-to-one correspondence with the temperature intervals;
step S530: and respectively designing a plurality of constant temperature tests according to the average temperatures, wherein the constant temperature tests form the first constant temperature scheme.
Specifically, after the first processing temperature threshold is obtained, the temperature interval is divided according to a gradient, and the first division result is obtained. The first division result includes a plurality of temperature intervals. The average temperature is calculated in each temperature interval, and as the difference of the influence degree of the fire resistance of the first bus duct in each temperature interval is not large, the average value can be taken, so that the test times are reduced, the test efficiency is improved, and the test cost is reduced. And then respectively designing a plurality of constant temperature tests according to the average temperatures, and forming the first constant temperature scheme by the constant temperature tests, wherein the average temperatures correspond to the temperature intervals one by one. Therefore, the technical scheme for testing the fire resistance of the first bus duct at the constant temperature is established, and the technical effect of foundation is laid for the subsequent fire resistance evaluation of the first bus duct.
Illustratively, the first processing temperature threshold is 800 ℃ to 1050 ℃, and the first processing temperature threshold is divided according to a condition that the fire resistance of the first bus duct in different temperature nodes changes, where the nodes are: 850 deg.C, 900 deg.C and 1050 deg.C. The divided temperature ranges are 800-850 ℃, 850-900 ℃, 900-1000 ℃ and 1000-1050 ℃, and the average values are respectively obtained according to the four temperature ranges, and the obtained temperatures corresponding to the four constant temperature tests are as follows: 825 deg.C, 875 deg.C, 950 deg.C, 1025 deg.C. And carrying out constant temperature test on the first bus duct according to the four temperatures.
Further, as shown in fig. 3, in the generating the first processing solution by using a control variable method according to the first processing temperature threshold, step S500 in this embodiment of the present application further includes:
step S540: extracting a first temperature interval of the plurality of temperature intervals, and screening the lowest temperature of the first temperature interval as a first lowest test temperature;
step S550: extracting the highest temperature of the first processing temperature threshold value as a first highest test temperature;
step S560: determining a first test temperature range according to the first lowest test temperature and the first highest test temperature;
step S570: obtaining a first temperature-changing test, wherein the first temperature-changing test refers to a temperature-changing test in which the test temperature randomly changes in the first test temperature range based on a preset temperature-changing frequency;
step S580: and determining a first temperature variation scheme according to the first temperature variation test, and generating the first treatment scheme by combining the first constant temperature scheme.
Specifically, the first temperature zone is any one of a plurality of temperature zones formed by dividing the first process temperature threshold value. And setting the lowest temperature in the first temperature interval as a first lowest test temperature, and taking the highest temperature of the first processing temperature threshold as the first highest test temperature, thereby obtaining the temperature change range of the temperature change test. The first temperature-changing test refers to a temperature-changing test in which the test temperature randomly changes in the first test temperature range based on a preset temperature-changing frequency. The preset temperature change frequency refers to the number of times of finishing temperature change in unit time, is set by a worker after the worker comprehensively analyzes the actual use environment, conditions and the like of the first bus duct, and preferably, a higher temperature change frequency is set for a bus duct use area with large day-night temperature difference change. Further, the first processing scheme can be generated according to the determined first temperature changing scheme and the determined first constant temperature scheme, wherein the first processing scheme is a scheme of performing a fire resistance test on the first bus duct by controlling other variables, optionally, wind speed, air pressure, humidity and the like and only changing the variable of temperature to perform test processing on the first bus duct and integrating two conditions of constant temperature and temperature changing. The technical effect that the fire resistance of the first bus duct can be comprehensively, accurately and efficiently tested, and the fire resistance can be accurately evaluated is achieved.
Illustratively, the first temperature range is 800 ℃ to 850 ℃, the first minimum test temperature is 800 ℃, the maximum temperature of the first processing temperature threshold is 1050 ℃, and the first maximum test temperature is 1050 ℃. And then obtaining the first test temperature range of 800-1050 ℃. And setting the preset temperature change frequency as the temperature is changed every half hour, and further determining the first temperature change scheme.
Further, as shown in fig. 4, in the step S600 of the embodiment of the present application, performing constant temperature processing on the first bus duct according to the first constant temperature scheme to obtain a first processing result, further includes:
step S610: carrying out constant temperature treatment on the first bus duct according to the first constant temperature scheme;
step S620: a thermocouple is used for detecting in real time to obtain a first actual processing temperature, wherein the first actual processing temperature refers to an actual temperature when the first constant temperature scheme carries out constant temperature processing on the first bus duct;
step S630: extracting a first standard processing temperature in the first constant temperature protocol;
step S640: and calculating to obtain a first temperature error according to the first standard processing temperature and the first actual processing temperature.
Specifically, in the constant temperature treatment of the first bus duct according to the first constant temperature scheme, the actual treatment temperature is detected in real time to be compared with the treatment temperature in the scheme, so as to obtain the temperature control error condition. Wherein, the real-time detection of the temperature is realized by a thermocouple. The first actual processing temperature is the actual processing temperature when the first bus duct is processed at a constant temperature according to the first constant temperature scheme, namely, the actual processing temperature is the real-time detection temperature in the test process. The first standard processing temperature refers to that after the plurality of temperature intervals are mentioned, average temperature values are obtained by calculating average temperatures of the temperature intervals, wherein the plurality of temperature intervals correspond to one average temperature value, and each average temperature value is used as a standard processing temperature during constant temperature processing of the temperature interval. And preferably, searching the scheme by taking the temperature as a keyword to obtain the first standard processing temperature. Thus, the first temperature error can be calculated according to the first standard processing temperature and the first actual processing temperature. Wherein the first temperature error is a temperature difference between a temperature set in the test scheme and a temperature in an actual test. The temperature error change data along with the processing time lapse is obtained through real-time detection and calculation, and the technical aim of intuitively quantizing the test error is achieved. The method and the device have the advantages that the basis is provided for screening the test scheme subsequently, and the technical effect of evaluating the fire resistance of the first bus duct is improved.
Further, in the obtaining the first analysis result, step S700 in the embodiment of the present application further includes:
step S710: judging whether the first temperature error meets a first preset temperature error threshold value or not;
step S720: if the first temperature error does not accord with the first preset temperature error threshold, removing the processing result of the corresponding constant temperature test to generate a first analysis scheme;
step S730: and according to the first analysis scheme, performing failure check and analysis on the first processing result to obtain a first analysis result.
Specifically, the first preset temperature error threshold refers to a preset error range, and if the difference between the actual test temperature and the standard test temperature in the test scheme is within the range, the influence of the temperature error on the test result is considered to be negligible. Specifically, the first preset temperature error threshold may be set by a worker, and is not limited herein. If the first temperature error does not meet the first preset temperature error threshold, the corresponding constant temperature test temperature control error is too large, and the first temperature error cannot be used as a basis for evaluating the fire resistance of the first bus duct and needs to be eliminated. And forming the first analysis scheme according to the constant-temperature processing result obtained after the elimination and the screening. The first analysis scheme is a specific scheme for further analyzing the fire-resistant condition of the first bus duct by analyzing the test result. And performing failure check and analysis on the first processing result, mainly analyzing whether the conductive function of the first bus duct is intact and whether the circuit integrity can be maintained in a flame state for a certain time to judge whether the first bus duct fails. Therefore, the technical effects of improving the test precision and improving the accuracy of the fire resistance evaluation of the first bus duct are achieved.
