Emergency heating method of emergency heating device for portable SF6 tank type circuit breaker

The invention relates to an emergency heating method of an emergency heating device for a portable SF6 tank type circuit breaker. At present, the existing SF6 tank type circuit breaker usually has a heating device for winter. Once the alarm is raised for low gas pressure due to the damage to the heating device, power outage will be required, and power supply to equipment will be affected. The emergency heating device includes an SF6 switch (1) of which the middle part is cylindrical. The outer diameter of the cylinder is sleeved with an emergency heating device (2) and a heating device (3). The emergency heating device is internally provided with a silica gel electric heating plate (4). A silica gel sleeve (6) is arranged outside the silica gel electric heating plate. The silica gel sleeveis provided with a silica gel slot. The silica gel electric heating plate is placed in the silica gel slot. The outer side of the silica gel sleeve is pasted onto an insulating plate (7) by special glue water for silica gel. The insulating plate is fixed to the switch through a buckle A (8) and a buckle B (9). The emergency heating method is used in an emergency heating device for a portable SF6tank type circuit breaker.
