Description

The detection system of quality is electrically connected between a kind of conductor
Technical field
The utility model relates to electric detecting technology field, in particular between a kind of conductor be electrically connected quality detection method and System.
Background technique
In various electrical components, electrically or electronically in device, electrical connection between generally existing conductor, such as direct current generator Electrical connection between rotor windings and commutator, the electrical connection between motor stator winding and outlet terminal.It is electrically connected quality It is to influence electrical component, electrically or electronically one of key factor of device reliability.
Electrical connection technique between conductor is divided into two kinds of welding and crimping.When welding or crimp quality are good, between conductor The contact resistance of junction is smaller.Conversely, the contact resistance of junction is larger between conductor when welding or crimp quality are bad. Therefore, the size of junction contact resistance is electrically connected quality between capable of characterizing conductor between conductor.
The contact resistance that junction between conductor is directly measured using four-wire system is the biography that quality is electrically connected between detecting conductor System method.However, junction between the conductor of many electrical components, electrically or electronically device, measures connector or probe can not be therewith Contact cannot construct four-wire system circuit to measure the contact resistance of junction between conductor, to cannot connect by directly measuring Electric shock resistance is to detect the electrical connection quality between conductor.
In consideration of it, how it is more enough provide it is a kind of not by directly measurement contact resistance can be detected conductor between be electrically connected matter The system of amount, has important practical significance.
Utility model content
The purpose of the utility model is to provide the detection systems that quality is electrically connected between a kind of conductor.
The utility model provides the detection system that quality is electrically connected between a kind of conductor, comprising: power supply, power distribution equipment, temperature Spend detection device, measure and control device and display device;
Wherein, the power supply is for providing between the electric current that junction is electrically heated the conductor;
The power distribution equipment makes current flow through institute for making junction and the electric power generating composition current loop between the conductor State junction between conductor;
