A kind of concentration bus duct side plate protective device
Technical field
The utility model belongs to bus duct technical field, and in particular to a kind of concentration bus duct side plate protective device.
Background technology
Bus duct is the metal device of a kind of closing being made of copper, aluminium busbar column, for for each element of decentralized system
Distribute relatively high power.Indoors more and more instead of electric wire in the power Transmission trunk project project of low pressure.
External developed country and Hong Kong, the Macao in China etc. have popularized.In the Guangzhou Guangdong in China, all 12 layers or more Building Power Distributions
Room outlet leads to 90% bus duct used above of backbone of floor;630KVA transformers to power distribution cabinet will use bus duct.
Bus duct is new circuit mode developed by the U.S., being referred to as " Bus-Way-System ", it using copper or aluminium as
Conductor, with non-alkene insulating supporting, the novel conductor that is then attached in metallic channel and is formed.Japanese really practical application be
Showa 29 years, bus duct is developed from then on.Nowadays build in high level, the electrical equipments such as factory, in electric system into
Indispensable wiring mode.Due to building, factory etc. it is various building electric power needs, and it is this need it is increased year by year
Trend, using original circuit wiring pattern, i.e. poling mode, when construction, brings many difficulties, moreover, when to change power distribution system
During system, it to be made to become simple, and some are nearly impossible, however, if using bus duct, are very easy to reach
To purpose, in addition also building can be made to become more beautiful.For economic aspect, bus duct is in itself compared with cable, price
It is more expensive, but can make construction cost using bus duct compared with the various attachmentes comprising wiring and entire electric system
Just it is cheap mostly, particularly current capacity it is big in the case of, such case is with regard to more obvious.

Conjunction is fixedly connected, and the inside of the busbar protection rubber cushion is enclosed with protection rubber cushion relief spring.
Preferably, it is provided with waterproof plastic pad at the cooling absorbent wool and the link position of busbar protection rubber cushion.
Preferably, the length of the protection rubber cushion relief spring is equal to 3/4ths of busbar protection rubber cushion maximum width.
Preferably, it is provided with circular hole on the outside of the busbar protection rubber cushion.
Preferably, the length of the cooling absorbent wool is equal to the length of busbar protection rubber cushion.
Compared with prior art, the beneficial effects of the utility model are:
(1) it is protected by devising the protection rubber cushion relief spring being mounted on inside busbar protection rubber cushion convenient for reducing busbar
Rubber cushion and the pressure at busbar side board sharp edge, solve existing concentration bus duct side plate protective device and are used in long-time
The problem of rubber cushion of busbar protection later is vulnerable to abrasion.
(2) it is convenient for dropping busbar connector by devising the cooling absorbent wool being mounted on the outside of busbar protection rubber cushion
Temperature solves existing concentration bus duct side plate protective device and asking for busbar heat dissipation is also prevented while busbar is protected
Topic.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
It please refers to Fig.1 and Fig. 2, the utility model provides a kind of technical solution:A kind of concentration bus duct side plate protection dress
It puts, including busbar trough floor 7, there are busbar side board 6, busbar in the upper surface both sides of busbar trough floor 7 by integral cast
Cooling absorbent wool 1 is provided on the outside of one end of slot side plate 6, busbar protection rubber cushion 3 is provided on the inside of one end of busbar side board 6,
And busbar protection rubber cushion 3 is glued to stick and is fixedly connected with cooling absorbent wool 1 by viscous glutinous agent, busbar protection rubber cushion 3 and busbar side board 6
By the way that rubber cushion fixing bolt 2 is protected to be fixedly connected, the upper surface of busbar side board 6 has been bolted to connection bus slot cover board
5, the rear surface of bus slot cover board 5 is provided with busbar connector 4, and busbar connector 4 with busbar side board 6 by being fixed
Connection, the inside of busbar protection rubber cushion 3 are enclosed with protection rubber cushion relief spring 8.
For the ease of preventing contact with moisture busbar connector 4, in the present embodiment, it is preferred that cooling absorbent wool 1 is prevented with busbar
It protects at the link position of rubber cushion 3 and is provided with waterproof plastic pad.
Rubber cushion relief spring 8 is protected for the ease of installing, in the present embodiment, it is preferred that the length of protection rubber cushion relief spring 8
Degree is equal to 3/4ths of busbar protection 3 maximum width of rubber cushion.
For the ease of protecting rubber cushion fixing bolt 2 and protecting the insertion of rubber cushion relief spring 8, in the present embodiment, it is preferred that
The outside of busbar protection rubber cushion 3 is provided with circular hole.
For the ease of covering busbar protection rubber cushion 3, in the present embodiment, it is preferred that the length of cooling absorbent wool 1 is equal to busbar
Protect the length of rubber cushion 3.
The operation principle and process for using of the utility model:The device is after installation is complete, by busbar protection rubber cushion 3 and cooling
Then absorbent wool 1 is placed busbar connector 4 and mother by the way that rubber cushion fixing bolt 2 is protected to be fixed on one end of busbar side board 6
Bus slot cover board 5 is finally fixed in the upper surface of wire casing bottom plate 7 using bolt, due to depositing for protection rubber cushion relief spring 8
When each busbar is contacted with busbar protection rubber cushion 3, can all reduce at busbar protection rubber cushion 3 and 6 sharp edge of busbar side board
Pressure, so as to reduce the loss of busbar protection rubber cushion 3, and due to the presence for the absorbent wool 1 that cools down, cooling absorbent wool 1 absorbs sky
Steam in gas, and stored, and when the temperature rise of busbar connector 4, the steam volatilization inside the absorbent wool 1 that cools down,
So as to cool down to cooling absorbent wool 1, fill up due to the presence of busbar protection rubber cushion 3, so as to cause busbar connector 4
The problem of subregion cooling is undesirable.
