技术领域 technical field
本发明涉及一种应用于熔断器寿命试验与评估系统中对熔断器组中各熔体温度进行测量与记录的熔断器自动测温系统。 The invention relates to an automatic fuse temperature measuring system used in a fuse life test and evaluation system to measure and record the temperature of each melt in a fuse group.
背景技术 Background technique
熔断器在使用过程中，由于自身流过的电流及外界环境的影响，其不可避免的发生老化降级，影响其使用寿命。已有研究表明，只要运行环境能够保证，熔断器的寿命主要取决于熔体的状态。熔断器的熔体在通电条件下的主要老化机理就是金属电迁移，即金属中的离子迁移，这种迁移会在局部区域发生质量亏损而出现空洞，或产生质量堆积而出现小丘或凝固态毛刺，造成金属缺陷，电阻增大，引发局部过热，熔体温度升高，高温又会加速金属化电迁移的过程，使缺陷进一步增大，逐渐累积至发生熔体熔断。 During the use of the fuse, due to the current flowing through itself and the influence of the external environment, it will inevitably undergo aging and degradation, which will affect its service life. Studies have shown that as long as the operating environment can be guaranteed, the life of the fuse depends mainly on the state of the melt. The main aging mechanism of the fuse melt under energized conditions is metal electromigration, that is, ion migration in the metal. This migration will cause mass loss in a local area and voids, or mass accumulation and hillocks or solidification. The burrs cause metal defects, increase the resistance, cause local overheating, and the melt temperature rises. The high temperature will accelerate the process of metallization electromigration, further increase the defects, and gradually accumulate until the melt melts.
在对熔断器进行寿命评估、变加速因子的寿命评估等试验时，需要测量熔体的温度。但目前，熔体温度测试依然采用手动测量与记录的方法，无法避免由测量时间、仪器使用方式、测量位置、测量角度、读数等带来的误差。 When performing tests such as life evaluation and variable acceleration factor life evaluation of fuses, it is necessary to measure the temperature of the melt. But at present, the melt temperature test still adopts the method of manual measurement and recording, which cannot avoid errors caused by measurement time, instrument use method, measurement position, measurement angle, reading, etc.

一种熔断器自动测温系统，用于在熔断器寿命评估系统中自动检测熔断器组1中各熔体11的温度，其包括测试装置2、控制装置3、设置于测试装置2上或控制装置3上的位移传感器。 An automatic temperature measurement system for fuses, which is used to automatically detect the temperature of each melt 11 in a fuse group 1 in a fuse life evaluation system, which includes a test device 2, a control device 3, set on the test device 2 or control Displacement sensor on device 3.
测试装置2包括温度传感器、带动温度传感器移动的行动机构。温度传感器为非接触式的红外热成像温度传感器。行动机构包括与温度传感器相固定连接并与控制装置相信号连接的步进式电机、与步进式电机相配合的轨道4，轨道4沿各熔体11的排布方向设置。位移传感器用于监测温度传感器位置。 The test device 2 includes a temperature sensor and an action mechanism that drives the temperature sensor to move. The temperature sensor is a non-contact infrared thermal imaging temperature sensor. The action mechanism includes a stepping motor that is fixedly connected with the temperature sensor and signaled with the control device, and a track 4 matched with the stepping motor. The track 4 is arranged along the arrangement direction of the melts 11 . A displacement sensor is used to monitor the temperature sensor position.
控制装置3为程控装置，其分别与温度传感器、行动机构、位移传感器相无线信号连接。控制装置3采集并存储温度传感器测得的各熔体11的温度数据，控制装置3控制行动机构移动。 The control device 3 is a program-controlled device, which is respectively connected with the temperature sensor, the action mechanism and the displacement sensor with wireless signals. The control device 3 collects and stores the temperature data of each melt 11 measured by the temperature sensor, and the control device 3 controls the movement of the action mechanism.
熔断器自动测温系统具有循环式测量和定点式测量两种工作方式，控制装置3根据熔断器组1的温度状态控制熔断器自动测温系统在两种工作方式之间转换。常规情况下，该熔断器自动测温系统处于循环式测量工作方式，此时，控制装置3控制步进式电机沿轨道4移动，温度传感器逐个测量各熔体11的温度并将测得的数据传回控制装置3存储。当所有熔体11的温度全部测量完时完成一次测量循环。相邻两次测量循环之间经过第一时间间隔，该第一时间间隔可在控制装置3中设定。若某一熔体11的温度的连续两次测量值之差大于第一温差时，熔断器自动测温系统自动转换为定点式测量工作方式。第一温差的值可根据实际情况在控制装置3中设定，例如设定为10℃。 The fuse automatic temperature measurement system has two working modes: cycle measurement and fixed-point measurement. The control device 3 controls the fuse automatic temperature measurement system to switch between the two working modes according to the temperature state of the fuse group 1 . Under normal circumstances, the fuse automatic temperature measurement system is in the cyclic measurement working mode. At this time, the control device 3 controls the stepper motor to move along the track 4, and the temperature sensor measures the temperature of each melt 11 one by one and the measured data Send it back to the control device 3 for storage. A measurement cycle is completed when the temperatures of all melts 11 have been measured.

The second time interval can also be set in the control device 3, and usually the second time interval is shorter than the first time interval, for example, the test frequency is set to 1 time/second. At this time, if the difference between the temperature of the melt 11 measured by the temperature sensor within the third time interval is less than the second temperature difference or the melt 11 is blown, the fuse automatic temperature measurement system will automatically switch to the cyclic measurement working mode . For example, if the third time interval is set to 5 seconds and the second temperature difference is set to 5°C, then if the temperature difference measured within 5 seconds is less than 5°C or the melt 11 is blown, the fuse automatic temperature measurement system will Automatically return to the cycle measurement work mode.
