ABB集团位列全球500强企业，集团总部位于瑞士苏黎世。ABB由两个历史100多年的国际性企业瑞典的阿西亚公司(ASEA）和瑞士的布朗勃法瑞公司(BBC BrownBover)）在1988年合并而成。两公司分别成立于1883年和1891年。ABB是电力和自动化技术领域的领导厂商。ABE的技术可以帮助电力、公共事业和工业客户提高业绩，同时降低对环境的不良影响。

PBSE5117使用要点

抗开扰措讫。来自电股的赍波，能造成系纳电任腋变，导致系功内电气设备的过电压、过负荷、过热甚至赞服元器件，造成叭C等接j设备银动作。所以，在电源入口处最好应设置屏蔽变压雒或电阕滤波等肪干扰设兹。其中，电源滤波器的地要以最短线路接到中央保护地。对于直流电源，则可加装微分电容加以干扰抑制。

保护接批。可采取用不小于10omm2的保护导钱接行配电板的保护批，相将的控制柜也应良妤接)钎并与地可靠逡接，同时顿的子防责保护接地，通觉可采取总牦电赟使用屏蔽电缆且屏蔽层两说接地，或模拟信目电统延取两层屏蔽，外层屏蔽两端接地等措施。另外，为防止感应雷进入系统，可采用浪涌吸收器。

做子信居屏蔽。信号的屏蔽非常关键，—般可采取屏蔽电绑佈传送健似信后。注意刘多个榄似信各共用一报多芯屏蔽电将就用两种屏蔽电将佈传送时，信号间一定要的屏蔽。而且电烧的屏蔽层一拽一股在控制柜鸠腰可专抽地当现场没有或无法设置硬点时，可在操作界面上采取软按键的方法解决走向选择或控制方式选择等问题。此外，与变频器、暂能仪表等的连接，最好还是采用信号线直接相连的方式。

应合理配置PLC的使用环境，提高乐统抗干扰能力。具体采取的措他有:远离高压柜、高频设备、动力屏以及高压线或大电流动力孩置。通信电练和境拟信号电频尽星不与其他屏(或没备共鸭电统的FPC柜的内不形我托等。另外，PLC虽适合工业现场，但使用中也应尽量避免直接震动和冲击、阳光直射、油露、雨淋等;不要在有腐蚀性气体、灰尘过多、发热体附近应用;避免导电性杂物进入控制器。

ABB Group is one of the world's top 500 companies and is headquartered in Zurich, Switzerland. ABB was formed in 1988 by the merger of two international companies with a history of more than 100 years: Sweden's ASEA and Switzerland's BBC BrownBover. The two companies were founded in 1883 and 1891, respectively. ABB is a leader in power and automation technologies. ABE's technology can help power, utility and industrial customers improve their performance while reducing their environmental impact.

Points to use PBSE5117

Anti-interference is checked. The STICKS wave from the electronics company can cause the electrical equipment to change, resulting in over voltage, over load, over heat and even over the components of the electrical equipment in the system, resulting in silver action of the equipment such as flash C and j. Therefore, it is best to set up a shielding transformer or electrical voltage filter and other interference devices at the power supply entrance. Among them, the ground of the power filter should be connected to the central protection ground with the shortest line. For DC power supplies, differential capacitors can be added to suppress interference.

Protect the batch. Can be taken with not less than 10omm2 of the protection guide money connected to the distribution board of the protection lot, the phase of the control cabinet should also be well connected) bit and reliably connected to the ground, at the same time, the sub-anti-fault protection grounding, general sense can be taken to use the total yake dielectric shield cable and the shield layer two said grounding, or analog electrical extension of two layers of shielding, grounding at both ends of the outer shield and other measures. In addition, to prevent induced thunder from entering the system, a surge absorber can be used.

Do the child trust house shield. Signal shielding is very critical - generally can be used to shield electrical tape after transmission of the message. Note that when two kinds of shielding cables are used to transmit the cloth, the shielding between the signals must be necessary. In addition, the shielding layer of electric burning can be pulled one by one in the control cabinet. When there is no or no hard point can be set on the scene, the soft key can be adopted on the operation interface to solve the problem of direction selection or control mode selection. In addition, the connection with the frequency converter, temporary energy instrument, etc., is best to use the signal line directly connected.

The use environment of PLC should be reasonably configured to improve the anti-interference ability of Letong. Specific measures taken include: stay away from high voltage cabinets, high frequency equipment, power screens, and high voltage lines or high current power devices. The frequency of the communication and simulation signal is not matched with other screens (or the FPC cabinet is not equipped with a common electrical system. In addition, although PLC is suitable for industrial sites, it should also be used to avoid direct vibration and impact, direct sunlight, oil dew, rain, etc. Do not apply in the vicinity of corrosive gases, too much dust, and heating bodies; Prevent conductive debris from entering the controller.
