In order to better meet the needs of large-volume data transmission and exchange, higher transmission requirements are imposed on the connector. However, in order to better save the space of the device and reduce its volume as much as possible, more and more Signal transmission, such as optical signals, microwave signals, power signals, and high-voltage signals, must be collected on a connector. At the same time, it is required that different signals can be transmitted independently without interference between terminals, which determines the integrated development of connectors in signal and transmission.
At present, the installation position of outdoor cable connection terminals is relatively concealed, and they are less likely to suffer direct lightning stroke. However, after all, some electrical cables are connected with overhead lines or other electrical equipment, maybe they will be invaded and affected by lightning current. So, to be foolproof, how to install the terminal to make the lightning protection effect good?
1. It has strict requirements on the terminals to be installed. If they do not meet the national standards, then they are absolutely unusable, so we need to grasp them at the source. Moreover, we need have a clear understanding of the use of the purchased terminals. The purchasing personnel shall visit more grassroots units to learn about the use of the purchased items in the installation process, collect the use opinions in time, select the cable accessories from the designated manufacturers of the country, and select good terminal blocks and hardware, so as to avoid the problems caused by the unqualified quality in the operation.
2. It is necessary to consider the power and capacity of the use r's electric equipment, so as to select the suitable terminal blocks and improve the safety performance. Pay attention to the field investigation. When making the plan of power consumption, it is necessary to distribute the three-phase load reasonably, and consider the economy of power consumption as well as the safety of power consumption.
3. When we install the terminal, we need to deal with the contact surface, for example, the contact surface of the connection terminal should be polished, and conductive paste should be applied. The purpose is to make the contact between the limit terminal and the lead clip good, meet the connection strength and electrical performance requirements of the connection terminal, and reduce the occurrence of heat generation.
4. The facilities affecting the safety of wiring terminal lines shall be cleared and rectified to ensure that there are no obstacles around the lines. The distribution lines led out by power cables shall be inspected regularly to reduce the peripheral fault factors and natural hazards of the distribution lines.
We must take more effective lightning protection measures to ensure the safe and stable operation of the terminals in the cable.
