Abstract

The invention relates to the field of vehicle engineering and electrical equipment, and discloses an energy-saving type starter control system with a self-protection function. The energy-saving type starter control system with the self-protection function comprises a compound relay, a starting unit, a reset unit and a self-protection unit; the compound relay, the starting unit and the reset unit are in electrical connection, and the self-protection unit balances the starting unit and the reset unit through magnetic force. According to the technical scheme, a permanent magnet is adopted to replace an original holding coil to improve the technical scheme, the design that neutral points of an engine is matched with a return coil control device in a voltage matching mode is utilized, the energy consumption problem, in the prior art, of the holding coil is solved, a gear reducer device can be prevented from being additionally installed or the rated power and the boundary dimension of a starter can be prevented from being reduced, and the cost of the starter and a vehicle is saved; meanwhile, the system has the self-protection function and the function of preventing secondary starting and igniting caused by misoperation, and the service life of equipment such as the starter, a storage battery and flywheels is prolonged.

Description

technical field

[0001] The invention belongs to the fields of vehicle engineering and electrical equipment, in particular to an energy-saving starter control system with self-protection function. Background technique

[0002] At present, the commonly used starter control circuit systems for engineering locomotives (automobiles) include: switch direct control type, type with starter relay and type with composite relay, etc.

[0003] The above background technology has the following defects: in the starting process of the switch direct control system, the key switch is easily damaged due to the fact that the current through the key switch and the electromagnetic switch coil is too large (generally more than 35A);

[0004] The system with starting relay uses the starting relay contact to control the electromagnetic switch of the starter, which reduces the current passing through the key switch during starting and prolongs the service life of the key switch. Collision damage oc...
