Arc contact assembly, arc extinguish chamber, load switch and gas insulated switchgear

The invention provides an arc contact assembly, an arc extinguish chamber, a load switch and a gas insulated switchgear, and belongs to the technical field of switchgears. The gas insulated switchgear comprises a load switch and a vacuum circuit breaker, the load switch comprises an arc extinguish chamber, the arc extinguish chamber comprises an arc contact assembly, the arc contact assembly comprises an arc contact and an insulated flow guide piece, and the insulated flow guide piece is provided with a flow guide head extending out of the arc contact. A guide channel is formed between the diversion head and the end part of the arc contact, and the guide channel is used for guiding air flow blown out of the arc contact to be sprayed all around and blown to the root part of the arc during opening. The arc extinguishing capability of the load switch is improved, when the capacitor is normally switched, the load switch is used as a main switch for switching on and off, and the success rate of switching on and sw
