Fireproof and explosion-proof capacitor for rail transit

The invention provides a fireproof and explosion-proof capacitor for rail transit, and relates to the technical field of rail transit capacitors. The capacitor comprises a shell, a core and a terminalconnector. A top plate is arranged above the shell, the terminal connector is arranged at the top end of the top plate, the core penetrates through an inner cavity of the shell and extends downwardsout of the shell, the bottom end of the core is connected with an installation column, installation bases are arranged on the periphery of the installation column and the bottom of the shell, and a fireproof and explosion-proof mechanism is arranged on the periphery of the shell. When fire and explosion happen in the shell, the heat-conducting glue adsorbs heat and diffuses and discharges the heatout of the fireproof shell, and fire prevention and flame retardance are achieved. A first explosion-proof spring and a second explosion-proof spring are elastically deformed to relieve severe deformation caused by explosion s
