Solar power system with temperature monitoring emergency device

The utility model relates to a solar power system with a temperature monitoring emergency device. A side wall of a center control connection shell is provided with a hollow de-electrostatic shell. A stretch-out end part of a conductive rod is provided with a thermal expansion assembly. A thermal expansion metal sheet body has a semi-arc-shaped structure which protrudes upward, and the top position of the semi-arc-shaped structure is fixed on the stretch-out end part of the conductive rod. A spring steel contact assembly is arranged under a rear end of a first metal plate. A PLC control panel has an LED display screen and a buzzer alarm which are connected with an electronic pressure gauge. The de-electrostatic shell is internally provided with a fluoroprotein foam cavity. According to the solar power system, the thermal expansion assembly is smartly adopted for monitoring temperature in the center control connection shell, a mechanical mode enables the pressure gauge to indirectly output a temperature value, and an alarm can be given out at the same time; and after a preset parameter is exceeded, a pressure release pipe can be started emergently, and the connection shell is filled with fluoroprotein foam, so that escalation of the accidental situation is prevented, and loss is reduced. Thus, the solar power system has a great practical value.
