Description
Technical field
The present invention relates to contact box, especially a kind of heat radiating type contact box.
Background technology
High-tension switch cabinet is one of most important part in electric system, with compact-sized, space is small, is easy to
The features such as repair and maintenance.Since it is just very likely caused as the connection hinge between power grid and user once breaking down
The serious consequences such as equipment damage or user's power failure.
The contact box and static contact of current existing high-tension switch cabinet are all sleeve-shapeds, and smaller static contact cylinder bottom end is solid
Dingan County is inside larger contact box.Because of the presence of self-resistance and contact resistance, heat is will produce when running, and it is high
Compress switch cabinet contact heat dissipation effect be influence its service life a major reason.If the heat dissipation of high-tension switch cabinet contact
It is not prompt enough or bad, gently then cause the switch cabinet contact scorification loss of power accident, it is heavy then explosion accident can occur, therefore high-voltage switch gear
The contact heat dissipation problem of cabinet is all paid attention to by manufacturer always.
In order to limit Wen Sheng, the operational reliability of switchgear is improved, over the years in the design and mounting process of insulating part
It also proposed many improvement.For this purpose, there is a kind of band heat emission hole in known field（Slot）Contact box, the contact box back（Or
Top）Design one（Or it is multiple）Heat emission hole（Slot）, to realize heat dissipation, improve the operational reliability of switchgear.But this change
It is into caused negative effect：It is real although the form being mutually communicated using the dynamic and static contact accommodating cavity of contact box and extraneous air
The purpose for having showed heat dissipation, but reduces the creepage distance and electric clearance of contact box, to reduce the practicability of contact box with
Versatility.
Technology contents
Present invention solves the technical problem that being good to overcome above-mentioned deficiency in the prior art to provide a kind of heat dissipation
Contact box.
In order to solve the above technical problems, present invention employs following technical schemes.
A kind of heat radiating type contact box, including tubular box body；The bottom of the box body opens, top seal, and the top
Metal insert with an installation high pressure static contact, the top outer of box body have the annular insulation wall extended to form upward,
The heat dissipation cavity that the annular insulation wall surrounds is installed and is radiated for busbar, and in the side of the annular insulation wall also with one for mother
The opening passed through is arranged, the thickness of annular insulation wall is more than 0.2cm, and is less than 2cm；Metal insert is pierced by upwards by the top of box body
It is exposed in heat dissipation cavity to be used to that busbar to be fixedly mounted.
Above-mentioned technical proposal can also be further perfect by following technical measures：
The inside of annular insulation wall is smooth surface, and outside has a plurality of annular rib for improving insulation performance,
The a plurality of annular rib parallel arrangement.
The inside of box body is smooth surface, on the outside of upper and lower part respectively have one group for improving the annular of insulation performance
Rib, two groups of equal parallel arrangements of annular rib.
Annular insulation wall is the U-shaped being open to side.
A U-shaped protection cover has been removably installed above annular insulation wall.
Box body is three and is arranged side by side that three box bodys are connected by Z-shaped mounting plate.
Z-shaped mounting plate has multiple longitudinally disposed connecting plates and two installation wing plates being laterally arranged, polylith connecting plate
It is integrally formed with box body and three box bodys is connected, installation wing plate is used to contact box being mounted in high-tension switch cabinet.
As a result of above technical scheme, the present invention has following advantageous effects：
Since the busbar and static contact of the contact box of the present invention are isolated in two spaces, and busbar is in open sky
In, thus heat dissipation effect be improved significantly, and the outlet due to expanding busbar, creepage distance and electric clearance are also big
It is big to increase, improve safety.

Specific implementation mode
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
A kind of heat radiating type contact box as shown in Figures 1 to 5, including tubular box body 1；The bottom of the box body 1 opens,
Top seal, and the top has the metal insert 3 of an installation high pressure static contact, the top outer of box body 1 has prolongs upward
The annular insulation wall 2 to be formed is stretched, the heat dissipation cavity which surrounds is installed and radiated for busbar, and exhausted in the annular
The side of edge wall 2 also with one for busbar by opening, the thickness of annular insulation wall is more than 0.2cm, and is less than 2cm, at this
In embodiment, the thickness of annular insulation wall is 0.8cm；Metal insert 3 is pierced by by the top of box body 1 and exposed is used in cavity upwards
In fixed installation busbar.
