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

The invention discloses a starting voltage drop control circuit for an electric wheel mine truck. The circuit comprises a start-stop switch, a control system flameout relay, a control system cut-off relay, an engine flameout relay and an engine start relay. The circuit disclosed by the invention can effectively control power supply of the control system and the control system can be normally started.

Description

Technical field [0001] The invention relates to a mining dump truck, in particular to a starting voltage drop control circuit for an electric wheel mining truck. Background technique [0002] When the engine is started, the electric-wheeled mining vehicle will cause the battery voltage to drop to the lowest value of the control system power supply voltage. In this case, the control system will be in a protective state, causing the control system to "crash" after the engine starts. Eventually cause the startup to fail. [0003] When the engine is started, the starter of a large electric-wheeled mining vehicle is in operation. At the moment the engine starts, it will generate about 6 times the full load current, and it will continue until the engine speed is close to the synchronous speed, causing serious voltage. drop. The electric-wheeled mining vehicle has a control system and adopts a modular design. Its rated voltage is DC24V. If the power supply voltage is lower than DC16.5V,...
