High-voltage remote power supply device with active safety protection function and interlocking protection method

Abstract

The invention discloses a high-voltage remote power supply device with an active safety protection function and an interlocking protection method. The high-voltage remote power supply device comprisesa plurality of sets of power converters, an electronic load electrically connected with the power converters through a back plate, a high-voltage output section matched with the power converters, a cable terminal box, a power distribution box, and a cabinet with a bottom layer empty box at the bottom, wherein the power distribution box is configured to comprise multiple power outputs; a circuit breaker passed by each power output realizes output state switching; the power outputs match with a main circuit breaker set and auxiliary circuit breakers according to current magnitudes of devices connected with the power outputs; the main circuit breakers are provided with a first mechanical lock; and a sliding plate is connected to the lower part of a rotating rod of the first mechanical lock through a pivoted crank. According to the high-voltage remote power supply device with the active safety protection function, the passive protection can be changed to the active protection through thestructure design of the power distribution box, so that the device has the higher safety performance.

Description

technical field [0001] The invention relates to the field of high-voltage power supply. More specifically, the present invention relates to a high-voltage remote power supply device with an active security function and an interlock protection method. Background technique [0002] High-voltage remote power supply equipment refers to input low-voltage DC (such as ±48V) or AC (such as ~220V or ~380V) after power conversion, output DC voltage of thousands of volts or tens of thousands of volts, and output power of thousands of watts or tens of thousands of watts. Voltage or constant current remote power supply system. However, because the DC voltage output by the high-voltage remote power supply is very high, it has great safety hazards. Therefore, it is strictly forbidden for maintenance personnel to operate with power on during equipment maintenance, so as to avoid electric shock accidents and affect the life and health of operators. [0003] However, when the existing high-...

Problems solved by technology

[0003] However, when the existing high-voltage remote power supply equipment is overhauled, its safety protection depends on the safety protection awareness of the operator, and it is impossible to realize active protection to ensure the safety of the operator. In the prior art, the high-voltage power supply is usually realized through a circuit breaker The components of the power supply equipment are cut off to achieve safety protection, but the working status of each handle in the circuit breaker cannot be controlled, and then when misoperation occurs on site, electric shock accidents will occur, causing casualties. In order to prevent this phenomenon from happening , which requires later research to make the high-voltage remote power supply equipment have safety protection devices to endow the high-voltage remote power supply equipment with active safety protection functions during maintenance
