Abstract
The utility model relates to a composite wall bushing for a high/medium-voltage switch cabinet, which comprises a wall body and three bases, wherein the wall body is made of epoxy resin; static contacts of a three-phase isolating switch are respectively cast in the respective bases and positioned on the inner side of the wall body; three bus copper bars arranged on the outer side of the wall body are respectively connected with the respective isolating switch static contacts through fasteners; the periphery of each base on both sides of the wall body is provided with more than one external umbrella skirt; and the periphery of each bus copper bar on the wall body is provided with more than one internal umbrella skirt. The utility model has the advantage of small size, and can integrate the three-phase wall bushing, thereby saving the mounting space of the cabinet body and lowering the cost of the cabinet body.
Description
Technical field
The utility model relates to a kind of middle-high voltage switch and uses compound wall bushing, belongs to the fixed high-voltage switch cubicle technical field.
Background technology
Insulating support member when present known wall bushing great majority just pass various dividing plate as electric conductor and independent the use; Because not with the use that combines of other electrical equipment; Therefore must connect use through lead; This just makes the space of switch cubicle must be enough big, not only increase the manufacturing cost of switch cubicle, and along with the space of switch cubicle increases and makes the floor space increase.In addition; Present wall bushing three-phase all is independent the use; Therefore when wall bushing is installed on the cabinet, all need adjust, guaranteeing the feasible connection of respectively being on good terms, and when passing cabinet generation magnetic field eddy current; Also need it is installed on the corrosion resistant plate, further increased the manufacturing cost of cabinet again.
Summary of the invention
It is little that the purpose of the utility model provides a kind of volume, can be one with three-phase set, saves the middle-high voltage switch of cabinet installing space and cabinet manufacturing cost and use compound wall bushing.
The utility model is that the technical scheme that achieves the above object is: a kind of middle-high voltage switch is used compound wall bushing; It is characterized in that: comprise body of wall and three pedestals that epoxy resin is processed; The three-phase isolation switch fixed contact is cast in the pedestal separately respectively and is positioned at the inboard of body of wall; Three bus copper bars that are arranged on wall outer side are connected with separately static contact isolation switch through securing member respectively; The periphery that the body of wall both sides are positioned at each pedestal is provided with the above external shed of a circle, and the periphery that body of wall is positioned at each bus copper bar is provided with the above full skirt of a circle.
Wherein: said static contact isolation switch outside is provided with male and fomale(M&F), and the male and fomale(M&F) interlocking is on the male and female face of pedestal.
Said body of wall has to the perpendicular full skirt that extends below along the bottom of interior full skirt; The periphery of wall outer side is provided with the Connection Block more than six, and the inboard of body of wall is provided with the step fitting surface.
It is body of wall that the compound wall bushing of the utility model adopts the epoxy resin insulation material one-shot forming; And body of wall is provided with three pedestals, therefore can each static contact isolation switch be cast directly over the pedestal separately of body of wall, and three common securing members of bus copper bar are installed on the static contact isolation switch separately; Easy accessibility not only; And need not to take up room thereby reduced installing in the cabinet separately, practice thrift the cost of switch cubicle.In addition, the compound wall bushing of the utility model is an one with three-phase set, simultaneously each alternate through full skirt to guarantee enough creepage distances, can satisfy instructions for use.The utility model can need not use corrosion resistant plate, thereby promptly save the space with compound wall bushing integral installation on cabinet, and reduces the cabinet cost, installs and uses flexible.
