Description

20Kv switch cabinet special contact box Technical Field The utility model relates to the technical field of contact boxes, in particular to a contact box special for a 20kv switch cabinet. Background The 20kv switch cabinet (switch cabinet) is an electrical device, the external line of the switch cabinet firstly enters the main control switch in the cabinet, then enters the sub-control switch, and each shunt is arranged according to the requirement. Such as meters, self-control, motor magnetic switches, various ac contactors, etc. Contact boxes are used in 20kv switchgear. The contact box is an epoxy resin APG process pressure gel forming structure and is used for various handcart type switch cabinets, and the use condition is that the altitude is not more than 1000M. The special contact box of the traditional 20kv switch cabinet has the defects that the heat dissipation effect is poor in the use process of the contact box, the heat dissipation is not facilitated, in addition, the contact box is inconvenient to install in use, and the operation is not convenient and labor-saving. Disclosure of utility model The utility model aims to provide a contact box special for a 20kv switch cabinet, which solves the problems in the background technology. According to the technical scheme, the contact box special for the 20kv switch cabinet comprises a bottom plate and a cylinder, wherein a through hole is formed in the middle of the upper surface of the bottom plate, one cylinder is arranged on the upper surface of the bottom plate, close to the periphery of the through hole, and is welded and fixed with the bottom plate, a plurality of heat dissipation rings are sleeved on the outer side wall of the cylinder and fixedly connected with the cylinder, a threaded hole is formed in the middle of the upper surface of the cylinder, a rectangular plate is arranged above the right side of the cylinder and fixedly connected with the cylinder, round holes are formed in four corners of the upper surface of the bottom plate, and threaded rings are arranged in the bottom plate and fixedly connected with the bottom plate. Further, the rectangular plate is in communication with the cylinder. Further, the bottom plate is hollow and has an open bottom surface. Further, the threaded ring is in communication with the cylinder. Further, the diameter of the round hole is 0.2-0.4 cm. The beneficial effects are that: According to the contact box designed in the utility model, the plurality of radiating rings are arranged outside the cylinder, the radiating rings are annular, so that heat in the cylinder can be conducted to the body of the contact box, heat transfer is facilitated, the heat can be conveniently radiated outside, the round holes are formed in the bottom plate, and the threaded rings are arranged in the bottom plate, so that the contact box can be conveniently installed, and the operation is simple and convenient. Drawings FIG. 1 is a schematic diagram of the structure of the present utility model; FIG. 2 is a schematic cross-sectional view of the present utility model; fig. 3 is a schematic top view of the present utility model. In the figure, 1, a cylinder, 2, a rectangular plate, 3, a heat dissipation ring, 4, a bottom plate, 5, a threaded ring, 6, a threaded hole, 7, a round hole, 8 and a through hole.
