cockpit substation remote screen, screen communication network / voice / 2m signal / rs232 / rs485 signal port a variety of surge overvoltage protection;
substation 10kv high voltage surge chamber signal port network switch cabinet overvoltage protection.
power plants, hydropower systems room network / voice / 2m signal / rs232 / rs485 signal port a variety of surge overvoltage protection
network power surge centralized control center / voice / 2m port signals over-voltage protection
surge powered by the communications and information network room / voice signal port and other over-voltage protection
detail:
patented product, designed for the actual situation of power system applications development, iu height standard for 19-inch rack structure is mounted;
lightning protection devices have deteriorated over current alarm remote signal output interface, for maintenance personnel at the scene determined spd performance status, without disconnecting the line is detected, can be detected using a universal table; facilitate monitoring;
after the remote communication interface access to dedicated data acquisition unit can display the spd performance centralized state;
remote communication interface by the data acquisition unit and monitoring software platform for remote online monitoring;
protection unit is built into two levels of protection, energy level see a reasonable match, the output residual depression;
pluggable, various signal lightning module uses plug-in structure, easy maintenance and replacement;
can be any combination, rj45, l9, ch, rj11 different modules can be any combination of signals mine;
scalable, port channel different signals can be reserved position, the subsequent expansion is very convenient;
maintenance replacement is very easy and does not affect other signal circuit is working properly.
