In short, the electric arc protection device is designed for the internal arc fault of the switchgear. The purpose is to quickly identify the fault current and internal arc, so as to directly remove the fault in a short time. A lot of preparatory work needs to be done before equipment installation, such as measuring various dimensions on site.

First, according to the project configuration arc protection (for example, how many arc light sensors are required), go to the site to investigate the geographical distribution of the switchgear, and determine which switchgear the main control unit and arc light collector are specifically required to be installed in, mostly in the bus Pt cabinet, because these cabinets are generally empty and have enough space for installation, and actually open them for on-site investigation, Prevent other things from taking up space and cannot be installed.

The second is to determine how to route the optical fiber of the arc probe. After the installation location of the main control unit and arc light collector equipment is determined, actually measure the optical fiber length from each arc light probe to the main control unit or arc light collector, and summarize and calculate how many optical fibers the whole equipment needs.

Thirdly, the brackets and gaskets used to fix the arc probe, the ties used to fix the optical fiber and other tools, as well as the lamps for experiments should be prepared in advance.
