MTL浪涌保护器TP32系列介绍
TP32浪涌保护器专为保护现场总线系统上的过程变送器和设备而设计。TP32在备受赞誉的TP48系列的高规格基础上进行了改进，为现场总线变送器提供的浪涌保护水平甚至超过了某些变送器制造商提供的可选瞬态保护。
至关重要的接地连接通过发射机外壳实现，无需在发射机处单独设置接地连接或接地桩。TP32工作时，确保发射机电子元件不会受到线路与地之间瞬态电压的损害。任何以串联或共模瞬态形式出现的浪涌电流都会被转换为共模电压，此时发射机电子元件的电压会被暂时提升至更高的水平，然后自动（且无损地）“浮回"至正常工作状态。
TP32保护网络采用混合设计，由高功率固态电子元件和气体放电管组成，能够分流高达20kA的浪涌电流。 TP32采用316不锈钢外壳，具有机械耐久性，即使在严苛环境下也能多年免维护运行。外壳带有螺纹，适用于所有常用导管入口。提供1/2" NPT、20mm ISO和G 1/2"（BSP 1/2 英寸）螺纹入口版本。
安装简便，可轻松对现有装置进行改造升级。TP32与变送器电路并联，不会干扰总线的正常运行——在传输交流或直流信号时不会增加总线上的压降，同时始终安全地将浪涌电流接地，并将输出电压钳位在安全范围内。
The TP32 surge protection device is specifically designed to protect process transmitters and devices on fieldbus systems. The TP32 builds on the high specification of the acclaimed TP48 range to provide a level of surge protection for fieldbus transmitters in excess of the optional transient protection available from some transmitter manufacturers.
The all-important earth connection is made via the casing of the transmitter, negating the need for a separate earth connection or a ground stake at the transmitter. In operation, the TP32 makes sure that the transmitter electronics are never exposed to damaging transients between the lines and ground. Any surge current appearing as a series-mode or common-mode transient is converted into a common-mode voltage whereupon the transmitter electronics are temporarily raised to some higher voltage level before ‘floating’ down automatically (and without damage) to resume normal operation.
The TP32 protection network is a hybrid design consisting of high-power, solid state electronics and a gas discharge tube which is capable of diverting surges up to 20kA. Encased in a 316 stainless steel enclosure, the TP32 exhibits unparalleled mechanical durability providing years of maintenance-free operation in harsh environments.The enclosure is available threaded for all the common conduit entries.Versions are available for 1/2" NPT, 20mm ISO, and G 1/2" (BSP 1/2 inch) threaded entries.
Installation is simple and can easily be carried out retrospectively to existing installations. By connecting in parallel to the transmitter circuit the TP32 does not interfere with the normal operation of the bus – passing AC or DC signals without adding increased voltage drop across the segment while consistently diverting surge currents safely to ground and clamping output voltage to safe levels.
