Integrated underground dual-circuit automatic circuit breaker

Abstract

An integrated underground dual-circuit automatic line switch device comprises: a housing with a door and a receiving space, the receiving space having a first subspace, a second subspace and a third subspace, wherein the first subspace is for inserting a feeder information terminal device; a fully sealed operating box disposed in the second subspace and electrically coupled to the feeder information terminal device; and a switch cylinder disposed in the third subspace and mechanically coupled to the fully sealed operating box, wherein the fully sealed operating box mechanically controls the opening and closing of the switch cylinder.

Claims

1. An integrated underground dual-circuit automatic circuit breaker device, comprising: a housing having a door and a receiving space, the receiving space having a first subspace, a second subspace, and a third subspace, wherein, The first subspace is used to insert a feeder information terminal device; a fully sealed operation box is disposed in the second subspace and electrically coupled to the feeder information terminal device; And a switch cylinder, which is located in the third subspace and is mechanically coupled to the fully sealed welding operation box, wherein the fully sealed welding operation box controls the opening and closing of the switch cylinder by mechanical force.

2. The integrated underground dual-circuit automatic line switch device as described in claim 1, further comprising the feeder information terminal device, wherein the feeder information terminal device is inserted into the first subspace.

3. The integrated underground dual-circuit automatic circuit breaker as described in claim 2, wherein, The feeder information terminal equipment has a charger and a battery.
