Abstract
The utility model relates to an identifier for the wiring state of a phase splitter, in particular to an identifier used for identifying whether the wiring state of the phase splitter is correct or not before the starting test of the phase splitter so as to avoid faults caused by starting the phase splitter under a wrong wiring state. The identifier for the wiring state of the phase splitter is mainly used for solving the problem that faults on the phase splitter and electric equipment, and the like, are possibly caused when the phase splitter is started under the wrong wiring state due to the unsymmetrical three-phase windings of the phase splitter; and in serious case, the equipment can be burnt to cause loss. In the identifier for the wiring state of the phase splitter, a 110V DC (direct current) provides a working power supply for an RLC (radio link control) circuit and an electronic circuit through a power supply; and the phase splitter and the RLC circuit form an oscillating circuit to generate three signals which form three pulses through a pulse forming circuit, and are outputted to a display circuit through a pulse comparison circuit to display the wiring state of the phase splitter. The identifier for the wiring state of the phase splitter has small size, is convenient to operate, and can avoid unnecessary losses caused by error wiring when the identifier for the wiring state of the phase splitter is used for identifying the wiring of the phase splitter.
