Abstract
The utility model relates to an electricity supply structure for motors of a two-stage partial ventilator, which is composed of the ventilator and the motors arranged on the ventilator, wherein the two motors of the two-stage partial ventilator are connected with each other by power supply wires; three-phase alternating current 380V electric network power wires provided by an electric network are connected with one motor of the two-stage partial ventilator to form the relation of connection in series, and only three heads are needed; each motor is additionally provided with a connecting wire screw sleeve, so the utility model has two connecting wire screw sleeves. A plurality of ventilators can be connected in series with a plurality of motors, and the wire connection mode of the two-stage partial ventilator is suitable for various series of two-stage partial ventilators. The utility model only needs three connecting heads which are directly connected in series with the electric network power wires by the power supply wires, thereby, the utility model saves one three-way terminal box, reduces the use cost of equipment and the work hours of equipment connection, increases the work efficiency, enables the construction to be simple and convenient and reduces the failure occurrence.
Description
Technical field:
The utility model relates to a kind of motor electric power-feeding structure that is used for the secondary booster in various mines, tunnel and other special producing place.
Background technology:
At present the secondary booster is widely used in various mines, tunnel and other special producing place, and multiple series, multiple structure are arranged, and its noise is low, blast is high, efficient is high, the inverted ventilation performance is good, is the ideal equipment of the enforcement local ventilation that can't replace now.But not having a kind of wiring construction on the motor supply power mode of secondary booster is conveniently, rationally, fast, all secondary boosters all are to adopt two motors, each motor connecting cartridge 1 is provided with a wiring swivel nut 5, causes and must use an independent threeway terminal box 3 to connect two motor of secondary booster in actual production process.On the mode of connection, being one group with three supply lines 2,4 needs wiring five statures altogether, concerning tens the secondary boosters in a mine the wiring trouble, efficient is low, cost is high.
Summary of the invention:
At above deficiency, the utility model proposes a kind of motor electric power-feeding structure of secondary booster, it by ventilation blower and on motor constitute, between two motor of secondary booster, connect by supply lines, the three-phase alternating current 380V electrical network power line that again electrical network is provided is connected on wherein motor of secondary booster, form series relationship, only need connect three statures.
Respectively increase a wiring swivel nut on the described motor, become two wiring swivel nuts.
Described ventilation blower and motor can be many and be connected in series.
The mode of connection of described secondary booster is applicable to the secondary booster of various series.
The utility model will need five joints originally and must could guarantee the operate as normal of secondary booster by a threeway terminal box, change into and only need three joints directly to connect with the electrical network power line with supply lines, not only saved a threeway terminal box, reduced the equipment use cost, and reduced connection device man-hour, increased operating efficiency, it is simple and convenient to construct, and has reduced the fault generation.
Description of drawings:
Fig. 1 is existing wiring construction schematic diagram.
Fig. 2 is a wiring construction schematic diagram of the present utility model.
Embodiment: reach embodiment in conjunction with the accompanying drawings and describe.
As shown in Figure 1, it is the motor power supply wiring construction of existing secondary booster, it by the secondary ventilation blower and on two flameproof motors constitute, one end of supply lines 2 is entered on the terminal block by a wiring swivel nut 5 on first motor connecting cartridge 1 and is connected with binding post, the other end of supply lines 2 is introduced in the threeway terminal box 3 and is connected with a set of connections terminal, another set of connections terminal in the threeway terminal box 3 is connected with electrical network power line 4, the 3rd set of connections terminal of threeway terminal box 3 is connected with an end of another root supply lines 2, the other end of this supply lines is entered on the terminal block by a wiring swivel nut 5 on second motor connecting cartridge and is connected with binding post, when the electrical network power line was connected, two motor on the secondary booster were switched on simultaneously and are started working.
As shown in Figure 2, be the motor power supply wiring construction of the secondary booster that provides of the utility model, it has respectively increased a wiring swivel nut on two motor connecting cartridges of secondary booster, and making has two wiring swivel nuts 5 on every motor connecting cartridge.During wiring, one end of supply lines 2 is entered on the terminal block by a wiring swivel nut 5 on first motor connecting cartridge 1 and is connected with binding post, the direct wiring swivel nut of introducing on second motor of the other end of supply lines 2 enters on the terminal block and is connected with binding post, on second motor connecting cartridge, electrical network power line 4 is entered with binding post on the terminal block by another wiring swivel nut and is connected, when the electrical network power line was connected, two motor on the secondary booster were switched on simultaneously and are started working.
