中波模块发射机目前世界上先进的中波全固态发射机,该机完全摆脱了电子管的束缚、效率高、电声指标好、故障率低、维护方便。但是,对静电的抵抗能力弱,特别是功率模块中的场效应管对防静电要求很高。一、静电的产生和危害在维护工作和日常生活中的大多数静电是由于不同物质的接触和分离或互相摩擦而产生的。例如,检修中的挤压、切割、擦洗、移动及生活中的行走、起立、穿、脱衣服等都会产生静电。因为,不同
Medium wave module transmitter At present, the advanced medium wave all solid state transmitter in the world can completely get rid of the shackles of the electron tube, has high efficiency, good electroacoustic index, low failure rate and convenient maintenance. However, the resistance to static electricity is weak, and especially the FETs in the power module are highly antistatic. First, the static electricity generation and harm Most of the static electricity in the maintenance work and daily life is due to the contact and separation of different substances or friction with each other. For example, overhauling squeezing, cutting, scrubbing, moving and living in walking, standing, wearing, undressing and so on will produce static electricity. Because, different
