Background technology
In prior art, the insulation resistance instrument can only be tested parts to the another one parts insulation resistance of (or over the ground) at every turn, the insulation resistance between can not a plurality of parts of one-shot measurement, when between a plurality of parts of needs tests during insulation resistance, need to measure repeatedly inefficiency, and easily test leakage.For example, when measuring the insulation resistance between the parts in threephase asynchronous machine, as: with heating tape, thermistor, just need the test winding insulation resistance of same heating tape, thermistor respectively, insulation resistance between thermistor and heating tape, heating tape, thermistor, winding difference resistance over the ground need test 6 minor insulation resistance altogether, need to press from both sides the joint of 6 ends to be measured with chuck, efficient is very low.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of primary connection can measure the intelligent multiplex Insulation Resistance Tester of the insulation resistance of a plurality of parts.
For achieving the above object, the technical solution used in the present invention is: the multiplex Insulation Resistance Tester of a kind of intelligence comprises single-chip microcomputer, relay K A1, relay K A2, relay K A3, relay K A4; Described relay K A1, relay K A2, relay K A3, relay K A4 are arranged in parallel; One end ground connection of each relay, the other end is communicated with single-chip microcomputer by triode; Each relay is electrically connected to bus by diode; Each triode is electrically connected to bus; Described bus is connected with single-chip microcomputer; Described relay K A4 controls the conducting of insulation resistance meter; When on insulation resistance meter, voltage being arranged, detected respectively the Leakage Current of the parts that are connected with relay K A1, relay K A2, relay K A3 by Single-chip Controlling.
Preferably, be provided with self-checking circuit on described single-chip microcomputer, described self-checking circuit is connected with LED1, LED2, LED3 respectively; When relay K A1 worked, LED1 lighted, and during greater than ratings, LED1 dodges when Leakage Current; When relay K A2 worked, LED2 lighted, and during greater than ratings, LED2 dodges when Leakage Current; When relay K A3 worked, LED3 lighted, and during greater than ratings, LED3 dodges when Leakage Current.
Preferably, described single-chip microcomputer is electrically connected to hummer; When LED1 or LED2 or LED3 sudden strain of a muscle, the hummer sounding alarm.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The present invention program's intelligent multiplex Insulation Resistance Tester is by primary connection, after energising, by the insulation resistance of 3 parts of the Single-chip Controlling automatic disposable measurement of energy.Certainly, if similar relay is set more, also can the be disposable insulation resistances that detect more parts more; Simple structure of the present invention, automaticity are high.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the circuit theory diagrams of the multiplex Insulation Resistance Tester of intelligence of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is the multiplex Insulation Resistance Tester of intelligence of the present invention, comprises single-chip microcomputer, relay K A1, relay K A2, relay K A3, relay K A4; Described single-chip microcomputer is the STC5204AD single-chip microcomputer; Described relay K A1, relay K A2, relay K A3, relay K A4 are arranged in parallel; One end ground connection of each relay, the other end is communicated with single-chip microcomputer by triode; Each relay is electrically connected to bus by diode; Each triode is electrically connected to bus; Described bus is connected with single-chip microcomputer; Described relay K A4 controls the conducting of insulation resistance meter; When on insulation resistance meter, voltage being arranged, detected respectively the Leakage Current of the parts that are connected with relay K A1, relay K A2, relay K A3 by Single-chip Controlling; Be provided with self-checking circuit on described single-chip microcomputer, described self-checking circuit is connected with LED1, LED2, LED3 respectively; When relay K A1 worked, LED1 lighted, and during greater than ratings, LED1 dodges when Leakage Current; When relay K A2 worked, LED2 lighted, and during greater than ratings, LED2 dodges when Leakage Current; When relay K A3 worked, LED3 lighted, and during greater than ratings, LED3 dodges when Leakage Current; Described single-chip microcomputer is electrically connected to hummer; When LED1 or LED2 or LED3 sudden strain of a muscle, the hummer sounding alarm.Be the insulation resistance of measuring each parts of motor in the present embodiment, the relay contact of relay K A1 is controlled the conducting of winding by the wire of white; The relay contact of relay K A2 passes through the conducting that red wire is controlled the conducting of PTC, controlled shell by double-colored wire; The relay contact of relay K A3 is controlled the conducting of heating tape by the wire of black.In addition, this programme is by the Power supply of 3.6V.
when the multiplex Insulation Resistance Tester of intelligence of the present invention uses, joint first switches on power, LED1 dodges successively one time to LED5 and carries out self check once, after self check finishes, LED6 dodges, enter holding state, when insulation resistance meter voltage being detected, begin conversion and detection of leaks electric current automatically by Single-chip Controlling, during conversion, corresponding LED lights, the circuit that corresponding relay automaticallyes switch and detects, when arbitrary group of line Leakage Current during greater than settings, corresponding LED begins to dodge, hummer is sounded, if detect electric current lower than setting value, enter holding state after detecting end, prepare to detect next time.
