Abstract
The utility model relates to a phase sequence-changeable three-phase five-wire plug. An A-phase plug and a B-phase plug are fixed on a two-phase plug rotating wheel which is clamped in a plug fixing block, and the plug fixing block can rotate along the axis; and a C-phase plug, a zero-line plug and a ground wire plug are fixed on the plug fixing block. The utility model belongs to the field of three-phase five-wire power supply plugs, the rear parts of three plugs belonging to a three-phase power supply are connected with the three-phase power supply by using screws, the middle part of the two-phase plug adopts the plugging and pulling mode, and is fixed on a rotatable circular wheel, when two plugs are pulled out from the middle parts, the circular wheel can be rotated manually to change the inner socket of the two-phase plug, and then the plug is re-inserted, so that the phase sequence change of two phases in the three-phase power supply is achieved; and the phase sequence-changeable three-phase five-wire plug can swiftly change the phase sequence of the three-phase power supply under the condition of not opening the plug, and can improve the working efficiency.
Description
Technical field
The utility model relates to a kind of Three-phase five-wire plug, especially can change the attaching plug of three phase mains phase place.
Background technology
At present, the Three-phase five-wire plug on the market generally has five copper pins, the plastic plug box, and compositions such as line ball screw, these five copper pins connect three phase mains, zero line and ground wire respectively.The staff is when connecting electric wire for the Three-phase five-wire plug and do not know the phase sequence of three phase mains, three phase sequences that can't guarantee power supply are consistent with desired three phase sequences of power supply unit, occur easily the Three-phase five-wire plug connect finish after, the staff closes a switch, reversal development appears in equipment, and the staff must open plug once more, changes the phase sequence that the Three-phase five-wire plug connects power supply, change the direction of rotation of equipment with this, cause unnecessary trouble to real work.In addition when an equipment replacement working region; transfer to new position; when the Three-phase five-wire plug is transferred to new gang socket; because three phase sequences of new working region power supply are different with original three-phase power supply phase sequence; also the power supply phase sequence occurring through regular meeting changes; the situation of equipment counter-rotating, the phase sequence that the staff must change three phase mains just can make equipment direction rotation according to the rules.
Summary of the invention
For fear of Three-phase five-wire plug phase sequence mistake after connecting power line, the equipment operation direction in the opposite direction, must open the situation that the Three-phase five-wire plug carries out the phase sequence transposing, the utility model provides a kind of Three-phase five-wire plug, the utility model is not at the power phase that three-phase power supply phase sequence and equipment requirements occur not simultaneously, the staff does not need to open plug and carries out power line accent preface, only need rotate device on the plug and can change the phase sequence of three phase mains, reduce unnecessary workflow, improved operating efficiency.
The technical scheme that its technical problem that solves the utility model adopts is:
The utility model is fixed on A phase plug, B phase plug on the two-pin plug runner, and the two-pin plug runner is stuck in the plug fixed block, and the plug fixed block can rotate along axis, and C phase plug, zero line plug and ground wire plug are fixed on the plug fixed block.
Described two-pin plug runner is by rectangle projection and the clamping of plug fixed block.
Adopt the utility model of technique scheme, in the Three-phase five-wire attaching plug, three plug rear portions under the three phase mains use screw to connect three phase mains, the plug form is adopted at wherein two-pin plug middle part again, and is fixed on the rotatable circle wheel, when these two plugs after the middle part unplugs, can rotate the circle wheel by hand, change the inner socket of this two-pin plug, and then insert plug, so just realized the wherein phase sequence of two-phase change in the three phase mains.Thereby the utility model can change the phase sequence of three phase mains rapidly under the situation of not opening plug, increase work efficiency.
