Description
Technical field
The utility model relates to power distribution equipment, especially relates to a kind of A.C. distribution box.
Background technology
AC distribution is the most widely used at present equipment distribution form, and A.C. distribution box is exactly to play a part to distribute or shunt current in ac power supply line.By A.C. distribution box, the electric power of one or minority power supply can be distributed to numerous equipment and use; One the road or several roads electric current can be divided into numerous branch currents, improved the power supplying efficiency of circuit and power supply.
The general input and output mode of present widely used distribution box is single, can not adapt to the input and output requirement of different configurations, cause distribution construction trouble, and cost is higher.
Now with a 9 road distribution boxs explanation, this distribution box is 1 tunnel 34 lines input mutually, 9 tunnel single-phase outputs, and its structure is as shown in Figure 1.The input of this distribution box is made up of air switch 1, air switch 2, air switch 3, zero terminal 10, ground wire terminal 11; Output is made up of air switch 12-20, zero terminal 10, ground wire terminal 11.Wherein the air switch 1 of input connects by the air switch 12,13,14 of distribution box inside cable 6 with output, because air switch 12,13,14 usefulness short-circuiting bars 7 connect, therefore the electric current by input air switch 1 is divided into 3 the tunnel and exports from the air switch 12,13,14 of input respectively.In like manner, the input current of air switch 2 is by air switch 15,16,17 outputs, and the electric current of air switch 3 is by air switch 18,19,20 outputs.
During use, with 1 the tunnel 3 mutually 3 live wires of 4 line system cables insert the air switch 1,2,3 of input respectively, zero line is received on the zero terminal 10, an independent ground wire is received on the ground wire terminal 11.And any one picks out a live wire from output air switch 12-20, picks out a zero line, picks out a ground wire from ground wire terminal 11 and just realized the single-phase output of 1 road 220V from zero terminal 10.Owing on zero terminal 10 and the ground wire terminal 11 enough wiring holes are arranged, so this distribution box can be divided into the single-phase output of 9 road 220V with 1 tunnel 3 phase, 4 line system 380V input at most.
Simultaneously, this distribution box also can be divided into 1 road 220V single-phase alternating current 3 tunnel single-phase 220V interchange outputs.Live wire with the single-phase cable of 1 road 220V during use inserts air switch 1, zero line inserts air switch 10, ground wire inserts air switch 11, correspondingly draws a live wire, a zero line, a ground wire respectively from air switch 12,13,14 and zero terminal 10, ground wire terminal 11 and just can realize that maximum 3 the tunnel import.
There is following shortcoming in the distribution box of above-mentioned prior art structure:
1, because per 3 short circuits of output air switch are one group, and every group independently of one another, can't realize that therefore 1 the tunnel imports 9 tunnel outputs, and input and output mode is single;
2, because therefore zero terminal output and import sharedly, can only be divided into 1 single phase alternating current circuit the output of 3 tunnel single phase alternating current (A.C.)s, and can not simultaneously 3 tunnel single phase alternating current (A.C.)s be divided into the output of 9 tunnel single phase alternating current (A.C.)s, because if like this, the zero line of 3 tunnel single phase alternating current (A.C.)s causes the zero line short circuit with regard to short circuit.
