Abstract

The invention discloses a two-way lightning protection box with RS485 monitoring data output, a power supply lightning protection system configured by two power supply systems is installed in one lightning protection box, there is no need to install a set of lightning protection system on each line, and the lightning protection systems of two loops can be monitored only through one lightning protection box system, so that the user cost is reduced, and the space utilization rate is increased. The two-way lightning protection box can monitor information such as the number of lightning strokes, the failure state of a lightning protector, the temperature of the lightning protector and opening and closing of an air switch in real time, and is connected to an intelligent lightning protection monitoring system arranged on the background or a monitoring system of a user through an RS485 interface.

Description

technical field [0001] The invention relates to power supply equipment, in particular to a dual-way lightning protection box with RS485 monitoring data output. Background technique [0002] The existing power supply and distribution lines are mainly in the single-loop power supply mode. With the rapid development of society and economy, hospitals, banks, fire-fighting power supply systems, elevator power supply, railway information machine rooms and some special power supply systems that do not allow power outages, which require relatively high power consumption, often use two-way loop power supply during circuit design , In case of failure of one power supply circuit, the other power supply circuit effectively guarantees the continuity and reliability of power consumption. Traditional lightning protection devices and lightning protection boxes are based on single-circuit power supply mode for line protection. When used in a double-circuit power supply system, a set of simi...
