Abstract
The utility model discloses a kind of low-voltage network to turn fast for contact cabinet, comprise cabinet and cabinet door, be provided with the first copper busbar and the second copper busbar in described cabinet, described first copper busbar is connected by isolating switch with the second copper busbar.Contact cabinet of the present utility model can switch fast, and integrated operation is convenient, installs also very convenient simultaneously, therefore has good market prospects.
Description
Technical field
The utility model relates to power control unit, particularly relates to a kind of low-voltage network and turns fast for contact cabinet.
Background technology
In prior art, transformer when certain region breaks down or needs maintenance, needs to carry out power failure operation to this transformer, and the transformer near usually adopting carries out transformer contact turn and supplies, or adopt generator car carry out generator car access turn confession, all need in these processes to use contact cabinet.
At present, the contact cabinet turned for operation of distribution adopts copper bar to connect mostly, causes turning longer for the time, and needs power operation, make whole work efficiency low, affect the use of user.
Utility model content
Based on this, the purpose of this utility model is to provide a kind of turning fast for contact cabinet for low-voltage network.
Concrete technical scheme is as follows:
A kind of low-voltage network turns fast for contact cabinet, and comprise cabinet and cabinet door, be provided with the first copper busbar and the second copper busbar in described cabinet, described first copper busbar is connected by isolating switch with the second copper busbar.
Wherein in an embodiment, the connected mode of described isolating switch is that plug-in connects.
Wherein in an embodiment, described isolating switch is fuse disconnecting switch.
Wherein in an embodiment, the outside of described cabinet is provided with connector.
Wherein in an embodiment, the side plate up and down of described cabinet is respectively equipped with the through hole for line.
Wherein in an embodiment, the material of described cabinet and cabinet door is ABS plastic.
Principle of the present utility model and advantage as follows:
The first copper busbar and the second copper busbar (copper bar employing T2 compression copper material is provided with in the cabinet of the utility model contact cabinet, the purity of copper is 99.9%), described first copper busbar is connected with a-power supply, described second copper busbar is connected with B-source, described first copper busbar is connected by isolating switch with the second copper busbar, is provided with fuse in described isolating switch.In normal power supply situation, the first copper busbar and the second copper busbar are off-state, and a-quadrant is powered by a-power supply, and B region is powered by B-source; When needs carry out distribution turn for time, such as a-quadrant transformer overhauls, and needs B-source to power to a-quadrant simultaneously, then the first copper busbar is communicated with the fuse of the second copper busbar by isolating switch.The operation principle of isolating switch changes main power source and stand-by power supply or changes the carrying out of two load equipments; there is the deixis such as charged, overload, electric current, protection; there are good fire resistance, dielectric property, carbonization resistance and shock resistance, reliably avoid the misoperation in A district and B district.
Contact cabinet of the present utility model adopts isolating switch (inside establishing fuse) to carry out the advantage connected:
(1) fuse established in isolating switch can be protected power supply unit, avoids causing because load is excessive damaging;
(2) can hot line job (adopt copper bar to connect in prior art, must, by the power-off simultaneously of a-quadrant and B region, just can carry out turning for operation);
(3) can select fuse according to the size of load, operate more flexible;
(4) connected mode of isolating switch is dismountable plug-in, flexible and convenient operation.
Also be provided with connector outside the cabinet of contact cabinet of the present utility model in addition, can be conveniently fixed on wall; Cabinet and cabinet door all adopt ABS plastic to make, and intensity is high, and water resistance is better simultaneously.
Contact cabinet of the present utility model can switch fast, and integrated operation is convenient, installs also very convenient simultaneously, therefore has good market prospects.

Embodiment
By the following examples the application is further elaborated.
With reference to figure 1-Fig. 4, a kind of low-voltage network of the present embodiment turns fast for contact cabinet, and comprise cabinet 1 and cabinet door 2, be provided with the first copper busbar 5 and the second copper busbar 8 in described cabinet, described first copper busbar is connected by isolating switch 6 with the second copper busbar;
Described isolating switch is fuse disconnecting switch, and connected mode is that plug-in connects;
The outside of described cabinet is provided with connector 3, can conveniently be fixed on wall;
The side plate up and down of described cabinet is respectively equipped with the through hole 4 for line;
Being made up of ABS plastic of described cabinet and cabinet door, intensity is high, and water resistance is good.
The first copper busbar and the second copper busbar is provided with in the cabinet of this contact cabinet, described first copper busbar is connected with a-power supply, described second copper busbar is connected with B-source, and described first copper busbar is connected by isolating switch with the second copper busbar, is provided with fuse in described isolating switch.In normal power supply situation, the first copper busbar and the second copper busbar are off-state, and a-quadrant is powered by a-power supply, and B region is powered by B-source; When needs carry out distribution turn for time, such as a-quadrant transformer overhauls, and needs B-source to power to a-quadrant simultaneously, then the first copper busbar is communicated with the fuse of the second copper busbar by isolating switch.
This contact cabinet adopts isolating switch (inside establishing fuse) to carry out the advantage connected:
(1) fuse can be protected power supply unit, avoids causing because load is excessive damaging;
(2) can hot line job (adopt copper bar to connect in prior art, must, by the power-off simultaneously of a-quadrant and B region, just can carry out turning for operation);
(3) can select fuse according to the size of load, operate more flexible;
(3) connected mode of isolating switch is dismountable plug-in, flexible and convenient operation.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
