Description
Technical field
The present invention relates to high-voltage board contact box, especially a kind of high-tension switch cabinet 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.
Current existing contact box and static contact are all sleeve-shapeds, smaller static contact cylinder bottom end be fixedly mounted on compared with
Inside big contact box.Because of the presence of self-resistance and contact resistance, when operation, will produce heat, and contact heat dissipation effect
Fruit is a major reason for influencing its service life.If the heat dissipation of contact is not prompt enough or bad, gently if cause switchgear
The contact scorification loss of power accident, it is heavy then explosion accident can occur, therefore contact heat dissipation problem always all by the weight of manufacturer
Depending on.
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 with tactile to overcome above-mentioned deficiency in the prior art to provide a kind of heat dissipation
Head cartridge.
In order to solve the above technical problems, present invention employs following technical schemes.
A kind of high-tension switch cabinet heat radiating type contact box, including tubular box body；The bottom of the box body opens, top
Closing, and the top has the metal insert of an installation high pressure static contact, the top outer of box body has to be extended to form upward
Annular insulation wall, the heat dissipation cavity which surrounds is installed and is radiated for busbar, and in the side of the annular insulation wall
Portion also with one for busbar by opening；Metal insert by the top of box body be pierced by upwards it is exposed in heat dissipation cavity for solid
Dingan County fills busbar.
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, this is more
Item 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 on interior.
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 space
It is interior, thus heat dissipation effect be improved significantly, and the outlet due to expanding busbar, creepage distance and electric clearance are also significantly
Increase, improves safety.
