The application provides an arc heater ballast resistor fireproof fixing device. The arc heater ballast resistor fireproof fixing device comprises a metal frame and a ceramic fixing assembly for fixing the ballast resistor on the metal frame, the ceramic fixing assembly comprises a first ceramic fixing piece, a second ceramic fixing piece and a ceramic buckle, the ballast resistor has a bending part and a connecting part connected with the bending part, the metal frame has a hollow part corresponding to the bending part, the first ceramic fixing piece is fixed in the hollow part of the metal frame, the second ceramic fixing piece is fixed on the metal frame, and the bending part and the connecting part of the ballast resistor are fixed on the first ceramic fixing piece and the second ceramic fixing piece through the ceramic buckle respectively. The arc heater ballast resistor fireproof fixing device solves the fire risk caused by the sharp rise of the surface temperature of the ballast resistor under the abnormal condition of large current or cooling water supply, and has the advantages of simple structure, light weight and high reliability.

The application discloses a kind of quick breaking electrical fire protection device, it is related to electrical fire protection device field, including fireproof shell and installation backplate, the bottom of fireproof shell is provided with dehumidification mechanism.This kind of quick breaking electrical fire protection device, by dehumidification mechanism can carry out dehumidification processing to equipment inside, blow heat dissipation fan can blow, can directly blow the air in the inner chamber of fireproof shell downwards, then cooperate with moisture fan, so that the humid air in equipment inside can be quickly sucked and removed, subsequently when humid air is sucked into the inner chamber of shell, will be sucked and removed with the dust blown off, effectively avoid that dust can be accumulated in the inside of fireproof shell, will not cause influence to electrical element, and by filter screen still can directly filter small dust, impurity etc., to effectively guarantee the dry degree of equipment inside, can also avoid to accumulate a large amount of dust, improve equipment service life.
