Abstract
The utility model relates to a plastic casing type circuit breaker. The tripping system of the plastic casing type circuit breaker especially comprises an electronic circuit composed of a shunt button, a power supply, a rectification circuit, a resistance and a diode. The button is connected with the power supply in series and input to the input end of the rectification circuit. Both ends of the output end of the rectification circuit are respectively connected with the resistance and the diode in series and then connected with both ends of a magnetic flux convertor coil. The magnetic flux triggered by an intelligent release and the shunt triggering are isolated by the diode. Because the electromagnetic conversion and the tripping function are realized by the electronic circuit and the magnetic flux convertor of the intelligent release, when the shunt button S is pressed, the circuit breaker is tripped, a contact is opened, the magnetic flux changer coil is cut off, the magnetic flux triggered by the intelligent release and the shunt triggering are effectively isolated by the diode without influence on each other, and the accessories of the plastic casing circuit breaker are consequently realized. A double auxiliary button, an alarm button, a shunt, and a voltage shortage button are simultaneously installed and intelligently controlled, which satisfies the requirement of the market.
Description
Affiliated technical field
The utility model belongs to a kind of circuit breaker, particularly relates to a kind of moulded case circuit breaker.
Background technology
Along with extensively being applied to rapidly in the low-voltage electrical apparatus field of electronic technology, intelligent circuit breaker is to answer the market demand and the novel breaker that is born, and its defencive function intellectuality, volume miniaturization, structure, accessory moduleization are inevitable development trend.At present known low-voltage intelligent circuit breaker by alone a cover shunted exciter tripping mechanism, the shunt opening trigger winding gets, the repulsion adhesive armature that overcomes spring is realized the function of dropout having influenced the installation of other annex like this, does not satisfy the demand in market in some cases.
The utility model content
The utility model provides a kind of magnetic flux and shunt opening that release can be triggered to trigger the moulded case circuit breaker that both isolate for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes contact system, arc quenching system, operating mechanism and tripping system, and above-mentioned four parts all are fixed in the case for circuit breaker, in described tripping system, include magnetic flow convertor and intelligent electrical apparatus release, it is characterized in that the electronic circuit that also includes shunt opening button, power supply, rectification circuit, resistance and diode composition in described tripping system; Be input to the input of rectification circuit behind described button and the power series, the output two ends of rectification circuit join with the two ends of magnetic flow convertor coil behind series resistor and the diode respectively again; Magnetic flux that intelligent electrical apparatus release triggers and shunt opening trigger both and pass through diode-isolated.
Advantage and the good effect that the utlity model has are: because the utility model is to utilize the magnetic flow convertor of electronic circuit and intelligent electrical apparatus release to realize that jointly electromagnetic conversion finishes tripping function, both ought press shunt opening button S, power supply enters and through rectification, the resistance current limliting, step-down, magnetic flow convertor gets electric (more than the direct current 0.6W), offset the magnetic field of magnet in the intelligent electrical apparatus release, spring discharges, circuit breaker tripping, open the contact, the magnetic flow convertor coil blackout, get electric to the time T＜15ms that triggers from magnetic flux, analyze from power consumption, whole load is exactly a resistance except magnetic flow convertor, resistance is resistive load, power consumption W=I*I*R*T, R is 0.5K, power 3W, electric current I=250MA, T=0.15ms, power consumption W are about 0.5＜3 joule, and resistance can not damage, magnetic flux that intelligent electrical apparatus release triggers and shunt opening trigger both by the diode effective isolation, be independent of each other, thereby realized the plastic casing circuit breaker accessory: be two auxiliary, report to the police, shunt opening, under-voltage can the installation simultaneously and Based Intelligent Control satisfied the demand in market.
