摘要本文主要通过测试Al/CuO复合半导体桥火工品经过静电放电后的点火性能的变化，分析了Al/CuO复合半导体桥静电防护效果，以及对1A1W5min实验和恒流激励下的温度变化进行了测试研究，判断是否具有良好的抗射频、抗杂散电流的能力，并为其安全性能研究提供定量依据。68582

研究发现：

（1）在国军标（500pF、5kΩ、25kV）条件作用下，6种桥型的Al/CuO复合半导体桥火工品均未爆发，说明Al/CuO复合半导体桥火工品具有一定的抗静电性能。而在美军标（500pF、500Ω、25kV）条件作用下，只有3号和5号Al/CuO复合半导体桥火工品能够通过静电放电实验。

（2）Al/CuO复合半导体桥火工品在恒流1A，作用时间5min条件下未发生变化，说明Al/CuO复合半导体桥具有良好的抗射频和抗杂散电流的能力，且经过1A1W5min实验后的Al/CuO复合半导体桥，性能未受影响。

（3）对6种桥型的Al/CuO复合半导体桥进行恒流测温时，只有1号桥爆发，而其它几种桥型的半导体桥均未发火，且温度均为不断上升到一定值后趋于稳定。说明除1号桥外，其它几种桥型的Al/CuO复合半导体桥具有较好的安全性能。

Title      The safety capability of the Al/CuO composite SCB  in constant current excitation                                           

Abstract

In this paper, by testing Al/CuO compound semiconductor bridge(SCB) change the performance of the ignition after electrostatic discharge, analyzes the Al/CuO compound SCB electrostatic protective effect,as well as tested 1A1W5min experiments and constant excitation temperature changes, to determine whether a good anti-RF, resistance to stray current and provide a quantitative basis for its safety performance studies.

The study found:

(1) Under the military standard (500pF, 5kΩ, 25kV) , six kinds of Al / CuO compound SCB no outbreak, illustrate Al / CuO compound SCB has some antistatic properties. While in the U.S. military standard (500pF, 500Ω, 25kV) condition, only the 3rd and the 5th Al / CuO compound SCB can through electrostatic discharge experiments. 

(2) After 1A1W5min experiment, Al/CuO compound SCB not changes, illustrate Al / CuO compound SCB has good resistance to RF and anti-stray current.

(3) Researched constant current temperature of six kinds of Al / CuO compound SCB, only the 1st bridge broke out, and several other bridge-type SCB were not exploded, and the temperatures are rising tends to a certain value. Illustrate except the 1st bridge, several other Al / CuO compound SCB has a better safety performance.
