Description

Power distributor

The utility model relates to a kind of Power distributor, and the power consumption equipment that it is suitably for the interim field operation use of all departments such as construction site, boiler erection, factory connects interim electrical source of power.

The present power consumption equipment that in the interim job sites of all departments such as industrial and civil buildings, boiler erection, factory, uses; generally all be in supply main, to connect power supply; only be provided with the interim power supply box of band disconnecting link switch between supply main and the job site power consumption equipment; because power consumption equipment such as motor, electric welding machine, electric hand tool etc. all do not have the safeguard protection of overload, short circuit, electric leakage, person electric shock; the job site is comparatively chaotic again, is difficult to management.Particularly when using many power consumption equipments, a lot of temporary tracks be need connect, therefore equipment and personal injury very easily caused, very dangerous.Job site power consumption equipment kind is more, and each power consumption equipment capacity difference uses the grade of supply voltage also different, does not therefore satisfy the needs of each power consumption equipment by the interim power supply box that sets up the disconnecting link switch.Interim power supply box can not move, and away from the power consumption equipment of interim power supply box, wiring will be very long, use also very inconvenient at the construction field (site) for this.

It is little that the purpose of this utility model provides a kind of volume, easy to use, complete function, safe and reliable Power distributor.

The purpose of this utility model is achieved in that it comprises and has two-sided opening the door and the casing that cable is imported and exported and the support of supporting box, it is characterized in that, be provided with two distribution boards in the casing, one of them is a fixed disk, be fixedly mounted in the casing, another is a movable plate, is connected with casing with articulated form, whole electric elements of Power distributor are divided on two distribution boards card outwardly, at the opposite face distribution of two distribution boards; Mid-stent is installed the reel have crank, is tied with standby electric power incoming line cable on the reel, and the support bottom is provided with two supporting overlines and walks wheel and one and turn to running wheel; The circuit of power distribution equipment adopts the automatic switch of electric leakage of a plurality of different capabilities with overload, short circuit, electric leakage or personal electric shock safeguard protection; with corresponding use of power consumption equipment that adapts to different capacity; adopt transformer and a plurality of socket inequality simultaneously; multiple supply voltage is provided, makes each power consumption equipment select corresponding voltage to use.

Characteristics of the present utility model are owing to adopt two distribution boards in casing, have made full use of cabinet space, and it is little to make it volume; Because mid-stent is provided with standby inlet wire cable and reel thereof, the support bottom is provided with running wheel, makes this power distribution equipment removable, and is easy to use.The automatic switch of electric leakage with overload, short circuit, electric leakage or personal electric shock safeguard protection of a plurality of different capabilities and the accessory power outlet of a plurality of electric pressures have particularly been adopted in the power distribution equipment circuit; make this power distribution equipment complete function; thereby avoided each power consumption equipment owing to the damage of transshipping, short circuit causes equipment, ensured electricity consumption personnel's safety.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the Power distributor shape assumption diagram.

Fig. 2 is a Power distributor casing sectional view.

Fig. 3 is a Power distributor casing internal fixation distribution board electric component layout plan.

Fig. 4 is a rotatable distribution board electric component layout plan in the Power distributor casing.

Fig. 5 is the Power distributor circuit theory diagrams.

With reference to figure 1～4, the utility model comprises and has two-sided opening the door and the casing 1 that cable is imported and exported and the support 2 of supporting box 1, and casing 1 is provided with two distribution boards, and one of them is a fixed disk 3, is fixedly mounted in the casing 1.Another is a rotatable disc 4, is connected with casing 1 with articulated form, is convenient to I﹠M, electric component air automatic switch ZK, the automatic switch of electric leakage 1ZK of Power distributor ₂, 2ZK ₂, transformer BK, fuse 1RD, 2RD, two hole socket 2CZ and automatic switch of electric leakage ZK ₁, 1ZK ₁A.C. contactor 1C, thermal relay 1RJ, Three-hole socket 1CZ, four spring hole scoket 3CZ, start and stop button 1QA, 1TA are divided on fixed disk 3 and rotatable disc 4 card outwardly, opposite face distribution at two distribution boards, mid-stent is installed the reel 5 that has crank, be tied with standby electric power incoming line cable 6 on the reel 5, the support bottom is provided with two supporting overlines and walks 7,8 and one of wheels and turn to running wheel 9.

With reference to figure 5, the utility model circuit is by air automatic switch ZK, automatic switch of electric leakage ZK ₁, 1ZK ₁, 1ZK ₂, 2ZK ₂, socket 1CZ, 2CZ, 3CZ, transformer BK, fuse 1RD, 2RD, A.C. contactor 1C, thermal relay 1RJ, start and stop button 1QA, 1TA form.Wherein forming single magnetic starter by A.C. contactor 1C, thermal relay 1RJ, start and stop button 1QA, 1TA uses for the frequent motor of starting.Automatic switch of electric leakage 1ZK ₁The motor that uses is played overload.The protective effect that short circuit, electric leakage or operating personnel get an electric shock.Automatic switch of electric leakage ZK ₁, 1ZK ₂, 2ZK ₂The power consumption equipment of capacity is correspondingly played the protective effect that overload, short circuit, electric leakage or operating personnel get an electric shock; socket 1CZ, 2CZ, 3CZ are suitable for the power consumption equipment of different electric pressures and peg graft; 1CZ is three hole 220V supply sockets; 2CZ is two hole 36V supply sockets, and 3CZ is four hole 380V supply sockets.When using this power distribution equipment, the air automatic switch ZK that closes earlier, when the power consumption equipment below the use 20KW (as electric welding machine), can closed 1ZK ₂, 2ZK ₂, when the motor below the use 15KW, closed 1ZK ₁, can start by 1QA, press 1TA when needing to shut down and get final product.When power consumption equipment uses 36V, 220V, 380V supply voltage, can be plugged into corresponding socket 2CZ, 1CZ, 3CZ, the above each power consumption equipment connects the X that corresponding electric component can use simultaneously, draw from automatic switch of electric leakage ₀₁, X ₀₂, X ₀₃Must be connected on the shell of power consumption equipment, when power consumption equipment overload, short circuit, electric leakage or the person got an electric shock, automatic switch of electric leakage was just cut off the electricity supply automatically, only after fault is excluded, just may realize sending once more the purpose of electricity, thereby ensure power consumption equipment operation and operating personnel's safety.
