Description
技术领域 technical field
本实用新型属于电缆制造领域，涉及一种海工设备用特种本安仪表电缆。 The utility model belongs to the field of cable manufacturing and relates to a special intrinsically safe instrument cable for marine engineering equipment.
背景技术 Background technique
伴随着全球能源开采向海洋的转移，海洋油气工程方兴未艾。由于海洋油气工程中充斥易燃易爆油污和气体，因此，对海工设备用电缆提出了“防爆”的要求。由于电火花和热效应是引发易爆气体爆炸的主要根源，而从系统布线角度考虑，由于电缆是由许多分布电容、电感等分布元件所组成，使其相应地成为储能元件，因此在信号传输过程中不可避免地存储一定的能量。一旦系统出现故障，这些储能就会以电火花或热效应的形式释放出来，影响系统的安全性。因此，要求电缆具有低电容和低电感，电缆本身所带的电荷要少，不易产生电火花；其次，要求电缆具有良好的屏蔽性能，具有优良的抗外电磁场干扰及不产生对外的干扰。这就要求电缆具有“本质安全”特性。因此，本质安全系统仪表电缆应具有低电容和低电感，并具有良好的屏蔽性能和抗干扰性能，防爆性能优于一般的普通型控制电缆和仪表电缆。 With the transfer of global energy exploitation to the ocean, offshore oil and gas engineering is in the ascendant. Because offshore oil and gas projects are full of flammable and explosive oil and gas, the requirements for "explosion-proof" are put forward for cables used in offshore equipment. Since electric sparks and thermal effects are the main causes of explosive gas explosions, and from the perspective of system wiring, since cables are composed of many distributed components such as distributed capacitances and inductances, they become energy storage components accordingly, so in signal transmission A certain amount of energy is inevitably stored in the process. Once the system fails, the stored energy will be released in the form of electric sparks or thermal effects, affecting the safety of the system. Therefore, the cable is required to have low capacitance and low inductance, the cable itself has less charge, and it is not easy to generate electric sparks; secondly, the cable is required to have good shielding performance, excellent resistance to external electromagnetic field interference and no external interference. This requires the cables to be "intrinsically safe". Therefore, the intrinsically safe system instrument cables should have low capacitance and low inductance, and have good shielding performance and anti-interference performance, and the explosion-proof performance is better than ordinary ordinary control cables and instrument cables.
因此，需要一种海工设备用特种本安仪表电缆以解决上述问题。 Therefore, a special intrinsically safe instrument cable for marine engineering equipment is needed to solve the above problems.
