Title:
PORTABLE EMERGENCY POWER
Document Type and Number:
WIPO Patent Application WO/2018/019240
Kind Code:
A1
Abstract:
A portable emergency power, comprising an intermediate frequency generator (1), an uncontrolled 12-pulse rectifying part (2), a serial/parallel switching knife switch (3), an emergency power switch (4), a DC ice-melting switch (5), an inverter (6), a DC ice-melting wiring device (7), and an ice-melting 3-phase jumper (9); the intermediate frequency generator (1) is in output connection with the uncontrolled 12-pulse rectifying part (2), the uncontrolled 12-pulse rectifying part (2) is connected with the serial/parallel switching knife switch (3), and the serial/parallel switching knife switch (3) is connected with the inverter (6) by means of the emergency power switch (4) to achieve a power supply function; the uncontrolled 12-pulse rectifying part (2) is configured to rectify an outputted current of the intermediate frequency generator (1), and after rectification, the outputted current is referred to as a rectified current; the serial/parallel switching knife switch (3) is configured to adjust an outputted voltage and the rectified current of the intermediate frequency generator (1), so as to meet the ice-melting requirements of various circuits and the power requirements thereof during power supply. The portable emergency power possesses functions of both DC ice-melting and emergency power supply, which expands the range of use.
