技术领域technical field
本发明涉及软磁材料测量技术领域，更为具体地，涉及一种高低温动静态软磁特性测量系统。The invention relates to the technical field of soft magnetic material measurement, and more specifically, to a high and low temperature dynamic and static soft magnetic characteristic measurement system.
背景技术Background technique
随着我国航天航空事业的飞速发展，对材料的性能要求越来越高，尤其是对使用在航天航空精密控制系统中的磁性材料的要求也越来越严格，特别是要预先确切知道在一定温度环境下应用的软磁材料的磁特性指标随温度变化的规律尤为重要，便于设计者考虑环境温度对软磁的磁性能的影响因素，才能确保航天航空器的精密控制，从而确保航天航空器的可靠运行。要求采用的测量方法满足国标软磁材料：国标GBT13012-2008_软磁材料直流磁性能的测量方法标准和国标GBT 3658-2008软磁材料交流磁性能环形试样的测量方法标准的同时，实现对软磁材料的磁性能特性参数常温精确测量的同时，还要求对应用在低温和高温环境中的软磁材料，进行高温和低温下的准确测量。With the rapid development of my country's aerospace industry, the performance requirements for materials are getting higher and higher, especially for the magnetic materials used in aerospace precision control systems. The law of the magnetic properties of the soft magnetic materials used in the temperature environment changes with temperature is particularly important. It is convenient for the designer to consider the factors affecting the magnetic properties of the soft magnetic material by the ambient temperature, so as to ensure the precise control of the aerospace vehicle, thereby ensuring the reliability of the aerospace vehicle. run. The measurement method required to meet the national standard for soft magnetic materials: national standard GBT13012-2008_Measurement method standard for DC magnetic properties of soft magnetic materials and national standard GBT 3658-2008 Standard for measurement methods for AC magnetic properties of ring specimens for soft magnetic materials While accurate measurement of the magnetic performance parameters of soft magnetic materials at room temperature is required, it is also required to perform accurate measurements at high and low temperatures for soft magnetic materials used in low and high temperature environments.
目前对软磁材料的测量一般有两种，冲击测量方法和振动磁强计测量方法。冲击测量法：现一般采用“MATS-2010SD软磁直流测量装置(含有直流励磁电源)和“MATS-2010SA软磁交流测量装置”(含有交流励磁电源)，这两种测量装置需要将软磁材料做成标准环，此装置价格便宜，能反应软磁材料的整体性能，测试准确，但是目前只能独立进行常温测量，不能进行低温和高温测量。振动样品测量法：国际上美国量子Quantum Design公司和英国Cryogenic公司均采用振动磁强计测量方法，仪器包括美国量子公司生产的综合物性测量系统和磁性测量系统，还有国内的一些仪器，虽然能进行高温和低温测量，但这类仪器测试的试样质量少至微克计量，只能对材料破坏性取样，表征的是材料某个微区域的材料磁性能，不能反应材料整体的磁性能，适合进行材料研究，不宜于材料生产的磁性测量，同时仪器价格昂贵，操作复杂，测量时对操作人员要求高，需专人操作，需液氦冷却，耗材昂贵。因此，目前对于在高温和低温环境中使用的软磁材料，测量其高温和低温磁性能，急需寻找一种价格便宜，操作简单，能表征整体软磁材料高温磁性能、低温磁性能的测量系统。At present, there are generally two types of measurement for soft magnetic materials, impact measurement method and vibration magnetometer measurement method. Impact measurement method: "MATS-2010SD soft magnetic DC measurement device (including DC excitation power supply) and "MATS-2010SA soft magnetic AC measurement device" (including AC excitation power supply) are generally used. These two measurement devices need soft magnetic materials Made into a standard ring, this device is cheap, can reflect the overall performance of soft magnetic materials, and the test is accurate, but at present it can only be used for normal temperature measurements independently, and cannot be used for low temperature and high temperature measurements. Vibration sample measurement method: International Quantum Design Company of the United States Both Cryogenic and the British company use the vibration magnetometer measurement method. The instruments include the comprehensive physical property measurement system and the magnetic measurement system produced by the American Quantum Company, as well as some domestic instruments. The mass of the sample is as small as micrograms, which can only be used for destructive sampling of the material. It characterizes the magnetic properties of a certain micro-region of the material and cannot reflect the overall magnetic properties of the material. It is suitable for material research, but not suitable for magnetic measurement of material production. At the same time, the instrument is expensive, the operation is complicated, and the requirements for the operator are high during the measurement. Special personnel are required to operate, liquid helium cooling is required, and the consumables are expensive. Therefore, at present, for soft magnetic materials used in high temperature and low temperature environments, it is necessary to measure their high temperature and low temperature magnetic properties. It is urgent to find a cheap, easy-to-operate measurement system that can characterize the high-temperature magnetic properties and low-temperature magnetic properties of the overall soft magnetic material.

为了方便表述，将进行直流测量的标准环称之为静态环。For the convenience of expression, the standard ring for DC measurement is called the static ring.
标准环悬挂在低温炉1或高温炉2内，不能同时在高温炉2和低温炉1内悬挂标准环的原因是MATS-2010SD软磁直流测量装置和MATS-2010SA软磁交流测量装置各自只具有一个磁化线圈接口和一个测量线圈接口，因此，MATS-2010SD软磁直流测量装置或MATS-2010SA软磁交流测量装置只能对一个标准环进行测量，本发明只能按照先测低温后测高温或者先测高温后测低温的顺序对标准环进行测量，具体地，以先测低温后测高温为例，先将标准环(动态环或静态环)放入低温炉中进行低温直流测量或低温交流测量，再将标准环(动态环或静态环)从低温炉内取出放入高温炉内，对标准环进行高温直流测量或高温交流测量。The standard ring is suspended in low temperature furnace 1 or high temperature furnace 2. The reason why the standard ring cannot be suspended in high temperature furnace 2 and low temperature furnace 1 at the same time is that the MATS-2010SD soft magnetic DC measuring device and the MATS-2010SA soft magnetic AC measuring device only have A magnetizing coil interface and a measuring coil interface, therefore, the MATS-2010SD soft magnetic DC measuring device or the MATS-2010SA soft magnetic AC measuring device can only measure a standard ring, and the present invention can only measure the low temperature first and then measure the high temperature or Measure the standard ring in the order of measuring the high temperature first and then the low temperature. Specifically, taking the low temperature measurement first and then the high temperature as an example, first put the standard ring (dynamic ring or static ring) into the low temperature furnace for low temperature DC measurement or low temperature AC Then take the standard ring (dynamic ring or static ring) out of the low-temperature furnace and put it into the high-temperature furnace, and perform high-temperature DC measurement or high-temperature AC measurement on the standard ring.
图2为根据本发明实施例的低温炉的结构。Fig. 2 is a structure of a low temperature furnace according to an embodiment of the present invention.
如图2所示，在低温炉1内开设有容纳槽，在容纳槽内设置有低温灌11，在低温灌11内充入有液氮，液氮能够降低低温灌11内的温度，为低温灌11提供低温环境，在低温灌11的外壁上绕制有电阻丝12，电阻丝12通过导线与低温炉控制柜15电性连接，在低温灌11内悬挂有标准环13；在低温炉控制柜15向电阻丝12通电后，电阻丝12对低温灌11进行加热，从而调节低温灌11内的温度，改变标准环13的测量温度。As shown in Figure 2, a holding tank is provided in the low-temperature furnace 1, and a low-temperature tank 11 is arranged in the housing tank, and liquid nitrogen is filled in the low-temperature tank 11, and the liquid nitrogen can reduce the temperature in the low-temperature tank 11, which is low temperature The tank 11 provides a low-temperature environment, and a resistance wire 12 is wound on the outer wall of the low-temperature tank 11. The resistance wire 12 is electrically connected to the low-temperature furnace control cabinet 15 through wires, and a standard ring 13 is suspended in the low-temperature tank 11; After the cabinet 15 energizes the resistance wire 12, the resistance wire 12 heats the low-temperature tank 11, thereby adjusting the temperature in the low-temperature tank 11 and changing the measurement temperature of the standard ring 13.
为了便于测量低温灌11内的温度，本发明通过一根测温管14测量低温灌11内的温度，测温管14的一端伸入低温灌11内，另一端与低温炉控制柜15连接，通过低温炉控制柜15显示测温管14测得的温度。In order to measure the temperature in the low temperature tank 11 conveniently, the present invention measures the temperature in the low temperature tank 11 through a temperature measuring tube 14, one end of the temperature measuring tube 14 extends into the low temperature tank 11, and the other end is connected with the low temperature furnace control cabinet 15, The temperature measured by the temperature measuring tube 14 is displayed through the low temperature furnace control cabinet 15 .
图3示出了根据本发明实施例的高温炉的结构。Fig. 3 shows the structure of a high temperature furnace according to an embodiment of the present invention.
如图3所示，在高温炉2内开设有收容槽，在收容槽内设置有绕制成中空的加热线圈21，加热线圈21通过导线与高温炉控制柜22电性连接；在加热线圈21的中空位置悬挂有标准环23，当高温炉控制柜22向加热线圈21通电后，加热线圈21对标准环23进行加热。As shown in Figure 3, a storage tank is provided in the high-temperature furnace 2, and a heating coil 21 wound into a hollow is provided in the storage tank, and the heating coil 21 is electrically connected with the high-temperature furnace control cabinet 22 through a wire; A standard ring 23 is suspended in the hollow position of the furnace. When the high-temperature furnace control cabinet 22 energizes the heating coil 21, the heating coil 21 heats the standard ring 23.
为了便于测量高温炉2内的温度，本发明通过一根测温管24测量高温炉2内的温度，测温管24的一端伸入高温炉2内，另一端与高温炉控制柜22连接，通过高温炉控制柜22显示测温管24测得的温度。For the convenience of measuring the temperature in the high-temperature furnace 2, the present invention measures the temperature in the high-temperature furnace 2 through a temperature-measuring tube 24. One end of the temperature-measuring tube 24 extends into the high-temperature furnace 2, and the other end is connected with the high-temperature furnace control cabinet 22. The temperature measured by the temperature measuring tube 24 is displayed through the high temperature furnace control cabinet 22 .
为了防止标准环23在高温炉2内氧化，高温炉2需要抽真空或充入惰性气体，因此，在高温炉2上设置有进气阀25和出气阀26，进气阀25通过气管连通有储气罐27，储气罐27内装有惰性气体，出气阀26通过连接管道连通有真空泵28，本发明先打开出气阀26，通过真空泵28将高温炉2内的空气抽走，然后再打开进气阀，由于高温炉2内的压强高于外部的大气压，在打开进气阀25时，储气罐27内的惰性气体被抽进高温炉2内。由于真空泵28不能完全将高温炉2内的空气抽出，因此，才向高温炉2内充入惰性气体，惰性气体能够防止标准环23在高温的条件下被氧化。In order to prevent the standard ring 23 from being oxidized in the high-temperature furnace 2, the high-temperature furnace 2 needs to be evacuated or filled with an inert gas. Therefore, the high-temperature furnace 2 is provided with an inlet valve 25 and an outlet valve 26, and the inlet valve 25 communicates with a Gas storage tank 27, inert gas is housed in gas storage tank 27, and gas outlet valve 26 is communicated with vacuum pump 28 through connection pipe, the present invention opens gas outlet valve 26 first, the air in high temperature furnace 2 is sucked away by vacuum pump 28, then opens and enters Gas valve, because the pressure in the high-temperature furnace 2 is higher than the external atmospheric pressure, when the inlet valve 25 is opened, the inert gas in the gas storage tank 27 is drawn into the high-temperature furnace 2 . Since the vacuum pump 28 cannot completely extract the air in the high-temperature furnace 2, an inert gas is charged into the high-temperature furnace 2, and the inert gas can prevent the standard ring 23 from being oxidized under high-temperature conditions.
