The contact box is cast into a one-piece structure in vacuum by employing epoxy resin; the inlet wire insulation sleeve and the outlet wire insulation sleeve are intersected with a circular column through a hemispheroid; and the two outlet wire terminals and the outlet wire insulation sleeve are arranged at two sides of the inlet wire insulation sleeve in a symmetrical distribution. The outlet wire terminals are plate-shaped with rectangular cross sections, and are arranged at the center of the outlet wire insulation sleeve. According to the utility model, the advantages of agile structure, convenient installation, large creepage distance and stable insulation are possessed.
Description
Technical field
The utility model relates to the contact box in the electric power system High-Voltage Insulation equipment, transition, insulating element on specifically a kind of metal-clad moveable formula switch cubicle.
Background technology
40.5KV metal-clad moveable formula contact box for switch cabinet is main electric transition and an insulating element in the electric power system metal-clad moveable formula switch cubicle; Make handcart or circuit breaker realize connecting with high voltage bus is electric through these parts, its installation site is in the main bus bar chamber of switch cubicle.The contact box outlet terminal of electric power system metal-clad moveable formula switch cubicle use at present is single outlet form, for female switch cubicle that requires that joins is arranged, needs increase transition copper bar to connect, and has shortcomings such as operation inconvenient installation, cost height, complex structure.The contact box that at present, can adapt to novel switched cabinet growth requirement does not appear in the newspapers as yet.
The utility model content
The purpose of the utility model is to above deficiency, and a kind of two leading-out terminal minor contact boxs that structure is flexible, easy for installation, creepage distance big, insulation is stable for adopting the epoxide resin vacuum cast to form are provided.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of switch cubicle is with two outlet terminal contact boxs; Comprise inlet wire fixed contact, inlet wire insulating sleeve, outlet terminal, outlet insulating sleeve, insulating mounting dividing plate, adopt the epoxide resin vacuum formula structure that pours into an integrated entity, the inlet wire insulating sleeve is joined through hemisphere and cylinder with the outlet insulating sleeve mutually; It is characterized in that; Two outlet terminals and outlet insulating sleeve in inlet wire insulating sleeve both sides, are symmetrical distribution.
Said outlet terminal is that the cross section is the tabular of rectangle, is symmetrically distributed in the center of outlet insulating sleeve.
The intracavity section of said outlet insulating sleeve is a rectangle, and outer periphery is distributed with the 1st full skirt.
Said inlet wire fixed contact is the cylindrical form of end band fillet, is arranged at the root in the inlet wire insulating sleeve.
Said inlet wire insulating sleeve intracavity section is circular, and outer periphery is distributed with the 2nd full skirt.
Said the 2nd full skirt size interval is arranged.
The utlity model has following advantage:
1, structure is flexible, easy for installation: the whole epoxide resin vacuum that adopts of the utility model is cast for integral structure; An outlet terminal is two outlet terminal structures; Make things convenient for busbar arrangement design in the switch cubicle, further improved the equipment and technology reliability of switch cubicle;
2, creepage distance is big, insulation is stable: the utility model inlet wire fixed contact and outlet terminal design respectively in the insulating sleeve center; Electric Field Distribution is even; Insulation is stable, and outside insulating sleeve is designed with the insulation full skirt that strengthens the surface creepage distance, and the surface creepage distance is bigger.

Fig. 4 is the utility model internal structure sketch map.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
A kind of pair of leading-out terminal minor contact box; Comprise inlet wire fixed contact 1, inlet wire insulating sleeve 2, outlet terminal 3, outlet insulating sleeve 4, insulating mounting dividing plate 5; Adopt the epoxide resin vacuum formula structure that pours into an integrated entity, inlet wire insulating sleeve 2 is joined through hemisphere 8 and cylinder with outlet insulating sleeve 4 mutually, guarantees that not only the product inside and outside has uniform electric field distribution; And product structure is compact more, installs more flexible.Two outlet terminals 3 and outlet insulating sleeve 4 in inlet wire insulating sleeve 2 both sides, are symmetrical distribution.
Said outlet terminal 3 is positioned at the center of said outlet insulating sleeve 4 for the cross section is the tabular of rectangle.
The intracavity section of said outlet insulating sleeve 4 is a rectangle, and outer periphery is distributed with the 1st full skirt 6.Being electrically connected of busbar in the convenient realization switch cabinet, outside the 1st full skirt (6) guarantees outlet terminal over the ground, has very big surface creepage distance, reinforced insulation.
Said inlet wire fixed contact 1 is the cylindrical form of end band fillet, is arranged at the root of inlet wire insulating sleeve.Inlet wire fixed contact 1 is the cylindrical form of end band fillet, realizes cooperating connections with handcart moving contact electric, and its position is arranged at the root of inlet wire insulating sleeve, and handcart can not take place when operating to discharge and corona phenomenon.
Said inlet wire insulating sleeve 2 intracavity sections are circular, and outer periphery is distributed with the 2nd full skirt 7.Effectively strengthen high voltage electric field insulation distance over the ground.
Said the 2nd full skirt 7 size interval are arranged.
The utility model is using the installation smoothly that can directly utilize 5 realizations of insulating mounting dividing plate and cabinet when installing; The interior bus row of outlet terminal 3 and cabinet employing bolt etc. is fixed; Not only as being electrically connected the transition terminal; And it is auxiliary as product lifting stationary device, the i.e. smooth installation of product.
