Abstract
The utility model discloses a contact box for movable-type switching devices. The contact box comprises a box body (1) with a round port and a rectangular port, wherein an umbrella skirt piece (4) is arranged at the part of the round port, and five screw holes (7) are formed on an embedded piece (3). The contact box has the advantages of good heat-dissipating capability, good insulating property and convenient installation.
Description
Technical field
The utility model relates to a kind of switchgear, and is special relevant with a kind of withdraw-type switch contact box structure.
Background technology
The withdraw-type contact box is the chief component of switchgear.Because contact box inside is the branch bar of switchgear, the place that fixed contact combines with the moving contact of circuit breaker, when working, switchgear can produce a large amount of heats, particularly power plant or large-scale industrial enterprise electricity capacity are big, and this just requires contact box to have good performance of heat dissipation.Existing contact box is made up of inserts, box body and full skirt, and long and narrow and its port inside of box body is provided with quite long full skirt, though strengthened creepage distance wind path is obstructed, and heat-sinking capability is not strong.Present this contact box only is used for little current switch cabinet.
Summary of the invention
The purpose of this utility model is exactly to design the good withdraw-type switch contact box of a kind of heat dispersion.
The technical solution of the utility model is: box body is provided with circular port and rectangular port, and the circular port outside is provided with full skirt, and this and existing contact box have than big-difference, can avoid wind path to be obstructed, and improves heat-sinking capability.The rectangular port inboard is provided with concave station, and inserts is cast in the box body.
The diffusing skirt of the withdraw-type switch contact box box body front end that the utility model provides has enlarged area of dissipation, has strengthened the creepage distance between contact and the mounting panel, and has guaranteed that wind path is unimpeded.The design of box body intracavity section helps hot-air like this and flows fast in cavity, reaches the purpose of rapid heat radiation.
Description of drawings
Fig. 1 is the structural representation of existing contact box;
Fig. 2 is the structural representation of an embodiment of the utility model switch contact box;
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, box body A 2, full skirt A 3, inserts A 4, inserts B 5, box body B6, full skirt B 7, screw
As shown in Figure 2, box body 1 is provided with circular port and rectangular port, and the circular port outside is provided with full skirt 2, and inserts 3 is cast in the box body.
During use, five bolts of fixedly employing of busbar and fixed contact and inserts 3 are connected on the one hand, make their tight contacts, reduce contact resistance, reduce the generation of heat; The design of contact box body cavity body can make heat flow through from conductive surface fast with air on the other hand, thereby reaches the purpose of quick heat radiating.The utility model heat-sinking capability is strong, good insulation preformance, easy for installation.Particularly suitable rated voltage 12Kv and following, rated current is to the switchgear of 5000A.
Claims (1)
- A kind of withdraw-type switchgear contact box comprises box body (1), inserts (3), and it is characterized in that: box body (1) is provided with circular port and rectangular port, and the circular port place is provided with full skirt (4), and inserts (2) is provided with 5 screws (7).
