Description

Technical Field

[0001] The utility model belongs to the technical field of distribution equipment and relates to a novel disconnector cabinet. Background Art

[0002] A switch cabinet is a set of power transmission and distribution electrical equipment (such as high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into a assembled sectionalized ring network power supply unit. Its core part adopts a load switch and a fuse, and has the advantages of simple structure, small volume, low price, improving power supply parameters and performance, and power supply safety. At present, mainly two methods of SF 6 gas insulation arc extinguishing and solid insulation vacuum arc extinguishing are adopted. However, the existing cabinet doors are usually hinged, and their opening and closing ends are locked by a buckle. After long-term use, the sealing strip is extruded and deformed due to uneven unilateral force on the opening and closing ends, resulting in a poor sealing effect of the sealing strip, causing the leakage of insulating gas or making the inside of the cabinet in a non-vacuum state.

[0011] A pull rod, which is arranged within the operating opening. One end of the pull rod extends into the second engaging portion and is provided with a second engaging portion, and the other end of the pull rod is connected to the first engaging portion;

[0012] The structure and size of the second engaging portion are adapted to the inserting portion, for passing the second engaging portion through the inserting portion and then rotating and engaging within the second engaging portion along the arc-shaped protrusion to achieve reverse tensioning of the cabinet door.

[0013] A sealing cover, which is installed on the pull rod and is arranged between the opposite surfaces of the cabinet door and the first engaging portion, for sealing the operating opening after the cabinet door is closed.

[0014] Optionally, the first engaging portion is a strip-shaped plate, and the first engaging portion is installed on the pull rod to form a T-shaped structure;

[0015] There are two sets of the first engaging portions, and the two sets of the first engaging portions are symmetrically arranged on both sides of the opening of the cabinet body, for the pull rod to drive both sides of the first engaging portion to rotate and engage on the two sets of the first engaging portions.

[0016] Optionally, the sealing cover is a shell with an opening on one side. The opening side of the sealing cover faces the cabinet door, and the opening of the sealing cover is not less than the outer diameter of the operating opening. A sealing ring is installed within the sealing cover, and the sealing ring is sleeved on the pull rod.

[0017] Optionally, the sealing ring is in a crescent shape, and there are two sealing rings. The open ends of the two sealing rings are butted together to form a ring.

[0018] The beneficial effects that the present utility model can produce include:

[0019] A novel isolating switch cabinet provided by the present utility model optimizes the opening and closing structure of the switch cabinet. When closing the switch cabinet, the cabinet door can be reversely tightened to achieve the overall force during the closing of the cabinet door, thereby avoiding the extrusion deformation of the sealing strip due to uneven unilateral force at the opening and closing end, and effectively ensuring the sealing performance of the switch cabinet.
