Problems solved by technology

[0005] It can be seen from the figure that when the engine starts, the voltage of the battery pack has an obvious voltage drop, and the bottom of the voltage drop is close to about 9VDC, which lasts about 10 seconds, which is seriously lower than the power supply voltage requirement of the control system. Seriously affect the normal start and work of the control system

Abstract

A circuit for controlling an activation voltage drop of an electric-drive mining vehicle. The circuit comprises an activation-termination switch (1), a control system extinction relay (2), a control system cut-out relay (3), an engine extinction relay (4), and an engine activation relay (5). The present invention effectively controls power supply to a control system (7) to ensure normal activation of the control system (7).

Description

technical field [0001] The invention relates to a mining dump truck, in particular to a control circuit for starting voltage drop of an electric wheel mining vehicle. Background technique [0002] When the engine of the electric wheel mining vehicle is started, the voltage of the battery pack will drop to the lowest value of the power supply voltage of the control system. In this case, the control system will be in a protection state, causing the control system to "crash" after the engine is started. Eventually the startup fails. [0003] When the engine of a large-scale electric wheel mining vehicle is started, the starter is in the running state, and the current of about 6 times that of the full load will be generated at the moment the engine is started, and it will continue until the engine speed is close to the synchronous speed, resulting in serious voltage drop. There is a control system on the electric wheel mining vehicle, and it adopts a modular design. Its rated ...
