The system operation
principle of the utility model is that the short circuit of the photovoltaic
module causes the overheating of cables and joints. Before the cables are
overheated and ignited, the customized high-temperature thrust device filled
with mercury liquid will reflect the super-high temperature. When the designed
temperature is exceeded or reached, such as 80-90 degrees Celsius, the mercury
liquid volume will be multiplied, and the thrust force of the normal contact
spring will be greater than that of the normal contact spring. The force acts
on the force bar. When the force of the force bar is higher than the normal
spring top contact thrust, the lead plate will be separated, and the internal
electrical circuit of the two sections of the male stamen structure will be cut
off, so that the current can not be turned on. All the electrical circuits of
the 20 photovoltaic modules in this series will be suspended without any
current output, so that fire can be prevented. Operating and maintenance
personnel can also take the first place. At one time, it was found from the
monitoring system and arrived at the specific site to deal with and eliminate
the danger.
