Capacitor shell expansion (also known as bulging), but also a common capacitor abnormalities. It is normal for a fuel tank to expand and contract with changes in temperature. However, when a partial discharge occurs inside the capacitor or the insulation is broken down, a large amount of gas will be

Capacitor is a fully sealed device, but due to manufacturing defects and improper use of maintenance, often lead to capacitor bleed oil, the capacitor is mainly the first part of the oil seepage casing, conductive rod sealing gasket failure, resulting in oil leakage. The second is the capacitor weld

Sometimes we will encounter a rather special situation, that is, after the performance of the capacitor capacitance that is worn, but after the failure and showed no breakdown, with a multimeter test it does not show the breakdown of the characteristics of electricity The DC voltage across the measu

From full customization to today's COTSPrevious views on the continued use of hybrid circuits and modules in military systems remain valid. It is important, however, to recognize that commercial pressure on military equipment manufacturers is greater than ever, especially in terms of costs and timin

SafetyObsolete elimination of products is a very serious problem for the military industry. 30 to 50 years of project life is common, so military and aerospace equipment suppliers are constantly looking for ways to reduce risk. Hybrid circuits and modules have been a way of trying to isolate the rap

PerformanceMilitary and aerospace systems are generally designed on the basis of modular subsystems. For example, field replaceable units (LRUs) simplify service and operational support. LRU interconnection relies on standards such as MIL-STD-1553 bus interfaces. Implementing these functions in hybr

IntegrationDuring the period covered in this article, ASIC technology brought about a revolution in the industry. At first, hundreds of gate arrays provided the military with a way to improve digital integration, and with the rapid increase in gate density and the improvement of development tools. T

When the capacitor is leaking, the insulation performance between the two poles of the capacitor is decreased, the leakage resistance exists between the two poles, there is a DC current passing through the capacitor, the straightness of the capacitor becomes worse, and the capacity of the capacitor

If the capacitor is broken down, it will also lose the function of the capacitor, because there is a path between the two pins of the capacitor, the direct action of the capacitor disappears, and the DC circuit of the circuit fails, thus affecting the AC working state.Solution: replace the breakdown

Problem description: if the capacitor has an open-circuit fault, then its line appears to be broken, lost capacity, that is, without the role of the capacitance. However, it should be noted that the capacitor has an open-circuit fault, in different circuits, the reason is different, need to be speci
