A three-phase primary pressure and primary flow device relates to a detection device. The current test device cannot synchronously output three-phase high voltage and three-phase high current, and cannot accurately verify the operation function, which can no longer meet the current needs. The invention includes a power control box, a three-phase integrated step-up transformer, and a split-type high-isolation current booster; the power control box is provided with a three-phase four-wire power input terminal, a ground terminal, a main power switch for incoming lines, and a voltage input switch. , Voltage output voltage regulator, current input switch, current output voltage regulator, voltage output terminal, current output terminal and voltage and current monitoring meter. The technical solution does not need to disconnect the secondary wiring, prevents false recovery, and has high accuracy.
Description
technical field [0001] The invention relates to a detection device. Background technique [0002] The rapid growth of electric power construction and the large-scale popularization of substations have put forward higher requirements for the reliability of the equipment put into operation before they are put into operation. The current test equipment cannot simultaneously output three-phase high voltage and three-phase high current, and cannot accurately verify the operation function, can no longer meet the current needs. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, to provide a three-phase primary pressure and primary current flow device, so as to achieve synchronous output of three-phase high voltage and three-phase high current, and can Exactly verify the purpose of running a function. For this reason, the present invention take...
