Gas insulation switch cabinet convenient for heat dissipation

The invention discloses a gas insulation switch cabinet convenient for heat dissipation, which comprises a shell, a bus chamber, a circuit breaker chamber and a cable chamber which are isolated from one another are sequentially arranged in the shell from top to bottom, and a static contact box is arranged in the circuit breaker chamber; a heat dissipation pipe is arranged in the shell; one end of the radiating tube is located in the circuit breaker chamber; the other end of the heat dissipation pipe is located above the top face of the shell. Cooling liquid is injected into the heat dissipation pipes. When the switch cabinet is in a switching-on operation state, the heat dissipation pipe absorbs heat conducted out from the lap joint pile head of the static contact box, and cooling liquid in the heat dissipation pipe conducts the heat to the top radiator for heat dissipation. Cooling liquid in the heat dissipation pipe is vaporized at high temperature and rises to the top heat dissipation device along the heat
