Electromagnet control electromagnetic system of energy-saving safety starting relay

Abstract

The invention provides an electromagnet control electromagnetic system of an energy-saving safety starting relay. The electromagnet control electromagnetic system comprises a starting switch (K), a switch (KJ) of a relay node or an electromagnet, and an electric motor (M); the starting switch (K) is connected with a power supply or the switch (KJ) of the relay node or the electromagnet; and the switch (KJ) of the relay node or the electromagnet is connected with the electric motor (M) in series, wherein the system further comprises a reliable pull-in judgment circuit, a resistance bridge voltage division triode conduction control circuit based on AND gate control and an RC time delay control circuit. The electromagnet control electromagnetic system of the energy-saving safety starting relay provided by the invention has the following advantages and effects: 1, after the reliable pull-in judgment is completed, the sustaining voltage of the starting relay or an electromagnet coil is reduced, the purpose of saving energy is achieved, and the problem that a control electromagnetic coil is overheated and burnt due to long-time work can be solved; 2, the time for starting the electromagnetic coil and a related control electric appliance is controllable: a safety starting controller is designed with a starting time control electromagnetic coil circuit, and a control circuit is used for accurately controlling the starting working time of the related electric appliance; and 3, the installation and use are convenient: an energy-saving safety starting controller adopts the integrateddesign of a control part and an execution part, so that the energy-saving safety starting controller can be directly replaced and installed for use on the basis that automobiles and motorcycles do notchange an original starting circuit and the external cable mode.

Description

technical field [0001] The invention relates to an energy-saving safety control device for starting relays of automobiles and motorcycles and electromagnets of electric control door locks, in particular to an energy-saving and safe start control electromagnetic coil system. Background technique [0002] The starter relay and the lock control electromagnet are one of the indispensable electromagnetic control switching devices on the car and motorcycle. The performance of the starter controller directly affects whether the car or motorcycle can start normally, and at the same time determines the condition of the starter motor and the battery. life. At present, the starting controllers used in automobiles and motorcycles usually use the starting switch to control the starting relay, and then directly control the starting motor after the relay contacts are connected. However, this starting method has the following disadvantages: [0003] In order to prevent misoperation and ant...
