The application discloses a transformer de-blocking of inrush current implementation method, device, medium and equipment. The method comprises the following steps: calculating the differential current sampling value mutation of the transformer corresponding to the sampling point in the first predetermined time interval; in the case that the differential current sampling value mutation of the two continuous sampling points meets the starting criterion, the time corresponding to the latter sampling point is determined as the first starting time; after the second predetermined time interval from the first starting time, in the case that the differential current sampling value mutation of the two continuous sampling points meets the starting criterion, the time corresponding to the latter sampling point is determined as the second starting time; after the first starting time, whether to send a blocking signal is determined according to the differential current sampling value mutation and the intermittent angle blocking criterion; whether to send a blocking signal is determined according to the differential current sampling value mutation of the two sampling points of the second starting time and the intermittent angle blocking criterion, and whether the transformer is de-blocked from the excitation inrush current is determined.

A PPU combined mechanical hand is characterized in that motors of X-axis movement modules, Y-axis movement modules and C-axis movement modules are all installed on a base and transmission connection is realized through light telescopic rods. Its advantages are that X-axis movement modules, Y-axis movement modules and C-axis movement modules are additionally arranged on X-axis guide rails of a PPU driving module, the limitation that a conventional PPU mechanical hand can only move for two-point grabbing is solved, and the PPU mechanical hand can meet automatic picking operation in a larger range; meanwhile, all motors for driving X-Y-C movement modules are installed on a machine base, and transmission connection is realized through light telescopic rods, the moving weight borne by the PPU driving module is greatly reduced, and thus the PPU driving module can move faster and the overall operation speed is improved.

This utility model discloses a high-voltage protection device for power input, comprising: a sensor module; the sensor module is used to collect voltage, current and temperature signals of the power supply in real time; this utility model introduces a MOSFET fast cut-off circuit, the MOSFET's operating speed is much higher than that of a mechanical relay, and it quickly cuts off the input power supply when high voltage is detected, protecting the downstream circuit, effectively dealing with transient high voltage impacts and avoiding equipment damage caused by slow response speed; based on the fast cut-off provided by the MOSFET, a varistor is used as an auxiliary protection element to absorb high voltage transient energy, further mitigating the impact of high voltage on downstream equipment. At the same time, varistor one is used to absorb transient high voltage impacts, and varistor two is used for backup protection under continuous high voltage conditions; by integrating a Wi-Fi communication module and an OLED screen, it provides comprehensive real-time monitoring, remote management and fault diagnosis functions, meeting the needs of modern intelligent equipment protection.
