Abstract
A 10kV contact box of 4000 A comprises a static contact and a contact box body. The forepart of the static contact is a cylinder, the rear part thereof is a flat body and the middle part thereof is provided with a flange. The contact box body is an insulator; the front part of the contact box body is in a cylindrical structure, the rear part thereof is in a semi-cylindrical structure and the middle part of an inner chamber thereof is provided with an annular partition wall; and the static contact is fixed on the annular partition wall in the inner chamber of the contact box body by the flange at the middle part. The rear part of the body of the static contact of the contact body is in a half open-type structure, is conveniently and reliably connected with a bus duct, has good head dissipation, can meet the electric requirements of rated operational current 4000A and rated short circuit current 50kA and can endure larger short circuit electrodynamic force.
Description
Technical field
The utility model relates to the contact box of a kind of power distribution equipment, particularly power distribution equipment.
Background technology
10kV withdraw-type controller switching equipment adopts circuit breaker cart as removing parts, and the grafting and the extraction of moving contact and contact box device upper static contact by circuit breaker cart realize the connection and the isolation of electric major loop.Consider the electric insulation distance, existing contact box device generally adopts enclosed construction, will connect busbar and fixed contact is enclosed in narrow space.Because of spatial relationship, busbar can only be connected with a screw with fixed contact.Existing contact box heat dispersion is poor, and it is unreliable that electric-conductor connects, and can not pass through bigger electric current, can not bear the above short-circuit electromotive force of 40kA.
The utility model content
The utility model aims to provide the 10kV contact box of a kind of 4000A, the conduction perfect heat-dissipating, and electric-conductor connects reliable, can pass through bigger electric current, can bear bigger short-circuit electromotive force.
The technical solution of the utility model is: the 10kV contact box of a kind of 4000A, comprise fixed contact, contact box body, described fixed contact front portion is a cylinder, the rear portion is a segment, and there is flange at the middle part, and described contact box body is an insulator, the front portion is columnar structured, the rear portion is the semi-cylindrical shaped structure, and the inner chamber middle part has annular to cut off, and fixed contact cuts off by the annular that central flange is fixed on the contact box intracoelomic cavity.
2 to 4 through holes are arranged on the segment of described fixed contact.
The segment of described fixed contact is connected with busbar.
There is flange at the middle part of described contact box external body.
Further, described contact box external body has raised line.
Preferably, the raised line of described contact box external body is continuous a plurality of.
Contact box body of the present utility model rear portion is the semi-open-type structure, conveniently is connected with busbar, connects reliably, and thermal diffusivity is good, can satisfy rated operational current 4000A, and the electric requirement of rated short circuit current 50kA can bear big short-circuit electromotive force.
Description of drawings
Fig. 1 is the utility model structural representation.
Mark among the figure: 1-busbar, 2-contact box body, 3-bolt, 4-fixed contact, 5-screw, 6-dividing plate, 7-bolt, 8-moving contact.
Specific embodiments
As shown in Figure 1, the utility model comprises fixed contact 4, contact box body 2.Fixed contact 4 front portions are cylinder, cylinder is pegged graft with moving contact 8 and is cooperated, fixed contact 4 rear portions are segment, through hole is arranged on the segment, and segment can be chosen the flat face of different sizes according to the electric current difference, its connecting hole quantity is according to busbar specification difference, can have 2 to 4, busbar 1 is connected with the segment of fixed contact 4 by bolt 3, and there is flange arrangement at fixed contact 4 middle parts.The insulator that contact box body 2 is made for insulating material, the front portion is a cylindrical shape, and the rear portion is the semi-cylindrical shaped structure, and the inner chamber middle part has annular to cut off, and fixed contact 4 is fixed on the annular partition of contact box body 2 inner chambers by the flange at its middle part.The annular partition is embedded with nut, with screw 5 fixed contact is fixed on the contact box body, and is easy to connect, firm.Certainly, also can cut off and be embedded in bolt, with the fixing fixed contact 4 of nut in annular.After fixed contact 4 was fixed on the contact box body 2, the anterior cylinder of fixed contact 4 was positioned at the anterior cylindrical shape of contact box body 2, and the rear portion segment of fixed contact 4 is positioned at the rear portion semi-cylindrical shaped of contact box body 2.The cylindrical space of contact box body 2 front portions can satisfy fixed contact 4 and cooperate requirement with the grafting of moving contact 8, and the semi-cylindrical shaped structure at rear portion is convenient to link together securely with the segment and the busbar 1 of bolt 3 with fixed contact 4 rear portions.
Further, there is flange arrangement at the middle part of contact box body 2 outsides, be fixed on the cabinet internal partition 6 with bolt 7 during installation, the sealing surface at contact box body 2 rear portions is towards cabinet internal partition 6, can satisfy the insulation distance requirement of fixed contact 4 and cabinet internal partition 6 fully, and open upper portion helps the heat radiation of busbar 1 and contact box body 2 inside.
Further, there is raised line described contact box body 2 outsides, and raised line strengthens electric creepage distance like the shirt rim structure, improve insulation property, and are preferred, and described raised line is continuous a plurality of.
Preferably, fixed contact 4 material of selecting for use copper, aluminium etc. to have optimum energy is made.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
