Description

一种测试熔断器抗浪涌电流冲击能力的装置以及方法 A test apparatus and a method of anti-surge current capability fuse

技术领域 FIELD

[0001] 本发明用于测试熔断器电流冲击能力和熔断特性,具体为一种测试熔断器抗浪涌电流冲击能力的装置以及方法。 [0001] The present invention is a method and apparatus for testing the impact of the fuse current capacity and fusing properties, particularly anti-surge current capability of testing fuse.

背景技术 Background technique

[0002] 在感性和容性的电路中,电路在开机时会产生瞬间的浪涌大电流,熔断器的熔丝受到浪涌冲击时会产生热胀冷缩的机械冲击效应,极端情况下,连续的多次浪涌冲击会使熔丝截面产生裂缝,甚至直接冲断熔丝,使熔断器失效。 [0002] In the inductive and capacitive circuits, the circuit will produce a large inrush current at startup moment, a mechanical shock is generated under the effect of thermal expansion and contraction, the extreme case when hit by a surge fuse the fuse, several successive sectional surge fuse will crack, or even direct thrust fuse the fuse failure. 本发明提供一种浪涌脉冲发生装置,模拟熔断器使用时可能受到的浪涌电流冲击,测试熔断器的熔断可靠性,量化熔断器熔断特性参数,使熔断器使用者对熔断器特性进一步掌握。 The present invention provides a surge pulse generating means, the reliability of surge current fuse when the fuse analog may be used to test the fuses, fuse blown quantizing characteristic parameters, so that the fuse of the fuse user more control characteristics .

[0003] 为掌握宇航用高可靠熔断器存在的潜在质量与可靠性问题,根据ECCC GenericSpecification N0.4008和MIL_PRF_23419G以及GJB5850等相关测试方法,对熔断器性能进行极限评估,采用常规加严试验条件或施加步进式应力的试验方法,考察高可靠熔断器的热应力、电应力等极限情况,摸底其极限能力。 [0003] To grasp a highly reliable fuse aerospace present potential problems of quality and reliability, according to the related test method and MIL_PRF_23419G ECCC GenericSpecification N0.4008 GJB5850 and the like, to fuse the limit performance evaluation, using conventional test conditions tightened or test method limit where stress is applied stepwise, a highly reliable fuse investigated the thermal stress, and other electrical stress, which limits the ability to thoroughly. 为在宇航严酷的应用环境下,提供参考依据。 As in the aerospace harsh environment applications, provide a reference.

[0004] 在极限评估试验中,抗浪涌电流冲击是必不可少的考察对象,因为在熔断器的应用电路中经常会产生短暂的浪涌电流,由于输入滤波电容迅速充电,所以该浪涌电流远远大于稳态输入电流,从而使熔丝产生机械疲劳,降低熔断丝寿命,甚至在有些情况下,它能够冲断熔断丝。 [0004] In the limit evaluation test, the anti-surge current inspection object is essential, because often transient surge current generated in the fuse circuit applications, since the input filter capacitor to the charging of the surge steady state current is much larger than the input current to the fuse to produce mechanical fatigue, decreased life of the fuse, and even in some cases, it can be washed off the fuse. 浪涌电流往往是多个的、连续的脉冲,会使熔丝产生热量,改变其熔丝阻值,因此对于宇航应用时,衡量熔断器是否能承受一定量的电流冲击是相当重要的。 Surge current often plurality of successive pulses, the fuse will generate heat, which fuses the resistance change, and therefore when for aerospace applications, to measure whether the fuse can withstand a certain amount of current impact is important.

[0005] 在极限评估试验中,熔断器安秒特性(熔断器的动作是靠熔体的熔断来实现的,当电流较大时,熔体熔断所需的时间就较短。而电流较小时,熔体熔断所需用的时间就较长,甚至不会熔断。因此对熔体来说,其动作电流和动作时间特性即熔断器的安秒特性,为反时限特性)也是需特别关注的特性。 When, when the current is large, the time required for the fuse to melt shorter [0005] In the evaluation test limit, the second safety fuse characteristics (operation blown fuse by the melt is achieved. Less current melt blown required for the long time, not even fusion. Thus the melt, its operating current and operating time characteristics of the fuse safety second characteristic i.e., inverse time characteristic) is of special concern characteristic. 因为熔断器的熔断特性主要考虑保护功能,希望其在电路出现故障过流时能够及时可靠切断电流。 Because major consideration fusing characteristics of the fuse protection, it appears desirable to timely reliably cut off the current circuit in overcurrent fault. 这就要求熔断器的熔断速度快一些;而熔化热能值主要考虑承载功能,希望熔断器在电路开关瞬间出现非故障脉冲电流时能够承受,这就要求熔断器的反应速度适当慢一些;因此需对熔断器的熔断时间进行极限考核,从而对在不同电流条件下,熔断时间有所掌握,指导设计师选用。 This requires faster speed of the fuse; the melting heat value of the load-bearing function major consideration, it is desirable to withstand the fuse circuit switching occurs when a non-pulsed current momentary fault, which requires an appropriate reaction rate slower fuse; therefore required time to blow fuse for stress assessment, thus at different current conditions, fusing some time to master, guiding the designer to choose. 因此,针对宇航用熔断器开展抗浪涌电流极限能力的测试,使用浪涌脉冲电流对熔断器进行电冲击。 Therefore, for testing aerospace fuses to carry out anti-surge current limit capability, the use of surge pulse current fuses electric shock. 通过测量熔断器阻值变化率、电压降等参数,评估熔断器的抗浪涌电流能力。 By measuring the rate of change of fuse resistance, voltage drop, it evaluated the ability of the anti-surge current fuse.

[0006] 还需要针对宇航用熔断器开展不同电流条件下熔断器熔断时间的测试,从而得出安秒曲线。 [0006] needed for aerospace fusing time to carry out tests under different current conditions fuse with a fuse, so as to arrive safe second curve. 熔断器按照常规要求,不必进行脉冲电流性能测试。 Fuses in accordance with the general requirements, performance test pulse current is not necessary. 但对于航天用熔断器,由于高可靠性的要求,其抗浪涌电流冲击能力测试是很有必要的。 But for the aerospace fuses, due to the high reliability requirements of its anti-surge current capability test it is necessary. 因为在感性和容性的电路中,电路在开机时会产生瞬间的浪涌大电流,熔断器的熔丝受到浪涌冲击时会产生热胀冷缩的机械冲击效应,极端情况下,连续的多次浪涌冲击会使熔丝截面产生裂缝,甚至直接冲断熔丝,使熔断器失效。 Because the inductive and capacitive circuits, the circuit will produce a large inrush current at startup moment, thermal expansion and contraction produces mechanical shock effects when hit by a surge fuse the fuse, in extreme cases, continuous surge times will fuse sectional crack, or even direct thrust fuse the fuse failure. [0007] 电路的浪涌电流波形是多样的,有可能是正弦波、三角波、锯齿波…,其能量是可以等效计算。 [0007] The inrush current waveforms of the circuit is varied, there may be sinusoidal, triangular, sawtooth ..., which is equivalent to the energy calculation. 常用的试验电路,可以采用'555'等电路搭建脉冲发生电路,图2所示,因为受制于电源,其脉冲电流值不会太高,太高的话,易产生过冲。 Commonly used test circuit, the circuit may be employed '555' and other structures pulse generating circuit shown in FIG. 2, because the subject power source, the pulse current is not too high, too high, easy to produce overshoot. 同时脉冲调制电路的脉冲占空比设置不能轻易改变。 While the pulse duty set pulse modulation circuit can not be easily changed.

[0008]目前普遍使用熔断器熔断特性测试仪有2种。 [0008] the current widespread use of fuse blowing characteristics tester has two kinds.

[0009] 一种是用恒流源搭建的测试台,图3所示,这种测试电路中的直流电源是市售的恒流电源,输出过载电流,在通过计时器(通常采用频率计)来同步记录熔断器的熔断时间。 [0009] A constant current source is built test rig shown in Figure 3, this test circuit DC power source is a commercially available constant current power supply, the output current overload, by a timer (usually frequency meter) blown fuse to synchronize time record. 这种测试装置实际使用有很受大的限制。 This test device has a practical use popular restricted. 主要缺点有:(1)输出中存在开关脉冲电流,电源使用的恒流电源是把市电通过整流、滤波、稳流来得到恒定的直流电流,其中必定存在着峰值电流相当大的开关脉冲电流,这种开关电流可以达到正常输出电流的好几倍,虽然时间只有几十或几百微秒,但足够可以对熔断器产生额外的冲击,甚至会直接冲断熔芯。 The main disadvantages are: a switching pulse current, constant current power supply used in the presence of (1) output is rectified by the mains, filtering, to obtain a constant direct current of constant current, where there must be a large peak current switching pulse current this switch current can reach several times the normal output current, although for only several tens or hundreds of microseconds, but enough to produce additional impact fuse, or even directly washed off the fuse. 航天用熔断器属于超快速反应的熔断器,其在600%熔断时的熔断时间只有几百微秒,所以用这种测试装置无法真实测量熔断器的熔断时间;(2)输出功率小,航天器用熔断器的测试条件与民用熔断器的测试条件有所差异。 Fuses space belonging to ultra-fast reaction fuses, which fuse fusing time only a few hundred microseconds at 600%, so this test device is not a true measure of time for fusing the fuse; small (2) output power, aerospace Used test conditions and civil fuse fuse test conditions vary. 航天器用熔断器的熔断时间测试需要测试电路的开路电压大于等于熔断器的额定电压,一般要大于等于125vdc。 Used open circuit voltage of the fuse space required test time is greater than the test circuit is equal to the rated voltage fuse, generally greater than or equal 125vdc. 同时熔断器的最大规格可达有15A,如果要进行61.(宇航极限考察要求)的熔断时间测试,测试电流要达到90A,这种大功率电源直流输出质量差,不能满足测试要求。 At the same time there are up to a maximum size of the fuse 15A, time fuse 61. If you want to test (limit visits aerospace requirements), the test current to reach 90A, the difference between this kind of high-power DC power supply output quality, can not meet the test requirements. 所以通常这类测试装置只能适合对开路电压没要求、且测试熔断点低的测试,如250%的低过载的测试。 Such test apparatus so usually only suitable for open-circuit voltage is not required, and the test low fusing point test, such as 250% overload test low.

[0010] 另一类测试仪使用了微处理器来避免加载过载的过冲,但这种加载的过载电流的建立时间过长。 [0010] Another type of tester uses a microprocessor to prevent excessive overshoot load carrier, but this load current overload too long settling time. 从图5中看出过载电流的建立时间到达了2ms,显然不适合600%熔断时间只为几百毫秒的测试。 Seen from FIG. 5 than the build overload current reaches 2ms, 600% is obviously not suitable fusing time test only a few hundred milliseconds.
