It is middle pressure handcart-type high-current switch cabinet in running current often reach 3000A and more than.Larger running current
Make switch cubicle caloric value very big, especially at switch cabinet contact box position, because of the closure of contact box structure, make dynamic in contact box
Heat caused by static contact operation can not be distributed effectively, and substantial amounts of heat aggregation makes dynamic/static contact temperature rise exceeded, longtime running
Very likely use electrification.
Utility model content
The above mentioned problem according to existing for contact box in the prior art, the utility model offer is a kind of to possess touching for heat sinking function
Head cartridge.
The technical solution of the utility model is as follows：
A kind of contact box for possessing heat sinking function, the contact box are arranged in high current handcart switch cabinet, described big
Outlet copper bar and copper static contact are additionally provided with electric current handcart switch cabinet, the contact box is cast directly over outlet copper bar
Together, only copper static contact is installed in later stage use, and the contact box includes openend and blind end, and the blind end is with going out
Line copper bar is fixedly connected, and the openend is towards moving contact.The utility model redesigns contact box structure, by contact box with going out
Line copper bar is cast directly over together, is had laid a good foundation for the design of integral heat sink structure.
As further improvement of the utility model, in high current handcart switch cabinet running, copper static contact with
The contact position of moving contact is that heat assembles position, is provided with heat dissipation channel on the outside of the contact box, the one of the heat dissipation channel
End is connected with heat aggregation position, and the other end outside contact box with being connected.Research is found, when switch cubicle is run, heat
Amount is largely assembled in the contact position of copper static contact and moving contact, and the design of heat dissipation channel is efficiently exhausted the heat,
So as to reduce electrification is used caused by heat is assembled.
As further improvement of the utility model, the position that contact box is stretched out in outlet copper bar is provided with radiating wing
Copper radiator.So, a heat part for aggregation discharges contact box by the heat emission hole of the utility model contact box bottom,
Another part is largely absorbed heat by the outlet copper bar in contact box, and heat is discharged into contact box using the radiating wing on copper bar.
As further improvement of the utility model, tip is provided with the top of the heat dissipation channel opposite with heat dissipation direction.
Summarized by many experiments, it is found that this structure design is scattered compared to not having cuspidated structure design that heat can be made quickly to flow to
The passage of heat is simultaneously discharged, and is advantageous to improve radiating efficiency.
The beneficial effects of the utility model are as follows：
The utility model redesigns contact box structure, and heat dissipation channel and heat dissipation equipment are devised in contact box, maximum
In degree by dynamic/static contact run caused by heat derives contact box, improve contact box service condition.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The structure of existing high current handcart switch cabinet 1 is as shown in figure 1, including existing contact box 2 and heavy current breaker
3, the structure of existing contact box 2 is as Figure 2-3.The running current of this high current handcart switch cabinet makes switch cubicle caloric value
It is very big, especially at the existing position of contact box 2 of switch cubicle, because of the closure of contact box structure, transport the dynamic/static contact in contact box
Heat caused by row can not be distributed effectively, and substantial amounts of heat aggregation makes dynamic/static contact temperature rise exceeded, and longtime running is very likely
Use electrification.
A kind of structure for the contact box for possessing heat sinking function of the utility model is as Figure 4-Figure 6.Contact box 10 be arranged at as
In high current handcart switch cabinet 1 shown in Fig. 1, outlet copper bar 4 and copper quiet is additionally provided with high current handcart switch cabinet 1
Contact 7.Together with contact box 10 is cast directly over outlet copper bar 4, copper static contact 7 is set to be arranged at the epoxy resin cavity to be formed
In 6, only copper static contact 7 is installed in later stage use.The structure of contact box 10 as seen in figs. 5-6, including openend and closing
End, blind end is fixedly connected with outlet copper bar 4, and openend is towards moving contact.The utility model redesigns contact box structure, will
