Abstract
The utility model relates to a switch cabinet external origin bus device, wherein a bus connector bar 2 and a side seal plate 5 of an origin bus are poured in the inner portion of a bus pouring body 7 according to fixed structures by using composite resin, the outside is covered with an origin case shell 4, one end of a PE bar 3 is connected with the origin case shell 4 through an earthing screw bolt 1, and the other end is connected with the side seal plate 5 of the origin bus, which guarantees the electrical continuity of a protective circuit. The side seal plate 5 of the origin bus is provided with two or a plurality of shoulder-shaped counterbores 8, the shoulder portions of the counterbores 8 are embedded in the pouring body in casting, which increases the connecting force between the side seal plate 5 of the origin bus and the bus pouring body 7, the counterbores can be used as connecting holes, which tightly connects the origin case shell with a pouring block through a self-tapping locking screw 6.
Description
Technical field
The utility model relates to a kind of external initial end bus device of switch cabinet.
Background technology
In the existing power transmission and distribution facility technology, the point of attachment of panel switches cabinet and power transmission busbar---external initial end bus device of switch cabinet product structure complexity, the top line bank that the phase line busbar is reserved has certain length, the installing space that takies is bigger, after line leading device connection is simultaneously finished, the initial end bus lead-in line row touches with top case side plate generation misconnection easily with stube cable, brings very big hidden danger to the safe operation of whole system.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of reliable external initial end bus device of switch cabinet is provided, and prevents that top that the phase line busbar is reserved from connecting row and touching with top case side plate.
The technical scheme that solves its technical problem employing is: utilize compound resin that bus line bank, the side seal board of initial end bus are poured into integral body by fixed structure; outer mask is with top case shell; PE arranges an end and is connected with top case shell by earth stud; the other end is connected with the initial end bus side seal board, has guaranteed the protective circuit electrical continuity.The initial end bus side seal board has two or more shoulder shape counterbores, its shoulder embeds in the pour mass when cast, increase the power that is connected of initial end bus side seal board and pour mass, its counterbore can also be used as connecting hole, by self-tapping lock screw top case shell closely is connected with castable.
The utility model device is owing to be integrated poured structure, after the installation castable effectively fixed support connect row, prevent that initial end bus line bank and top case side plate generation misconnection from touching, simultaneously with low cost, structural safety is reliable, can reach simple, easy for installation, the economical and practical purpose of technology.
