Abstract
The utility model relates to a breaker. A groove is opened at a reserved position of a side surface of the breaker; the specific position of the groove is below a terminal; the breaker also comprises a control circuit board and a communication wire of external connection; the communication wire of external connection is arranged in the groove opened in the side surface; and the communication wire of external connection is connected with the control circuit board through a lead, and the control circuit board is connected with a release coil through a lead. When a prepay ammeter or a remote line provides an incoming signal, control voltage is added to a shunt release through a line element; an excitation coil carries out induction; an iron core is attracted to move; a release rod is pushed; and the breaker is disconnected. When a current overload happens, bimetallic strips of an overload release generate deformation; a connecting rod is driven; a lock catch is pushed; and the breaker is released and disconnected. When a short circuit current passes through an electromagnetic system, a moving iron core is absorbed; a push rod is driven; the lock catch is pushed; the breaker is released; a contact is disconnected under the effect of a release spring; and protection effect due to disconnection of the breaker is completed.
Description
Technical field
The utility model relates to a kind of circuit breaker.
Background technology
What existing pre-paying kilowatt-hour meter adopted is direct analysis, and its circuit specification receives bigger restriction, and lacks overload and short-circuit protection function.The words that lack overload and short-circuit protection function can produce great puzzlement to the user.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and a kind of pre-payment circuit breaker is provided.
For realizing above-mentioned purpose; The utility model adopts a kind of pre-payment circuit breaker; Include case for circuit breaker, tripping coil, lead, binding post; The reserved location place, a side of circuit breaker offers a groove, and the particular location of this groove is below binding post, and this circuit breaker also includes a control circuit board and an external order wire; External order wire is installed in the groove of offering the side, all adopts lead to be connected between external order wire and the control circuit board and between control circuit board and the tripping coil.
Wherein, The control circuit intralamellar part and with tripping coil, external order wire connected mode be that external order wire connect with resistance R 1, R2, diode D1 successively, capacitor C 1 and resistance R 3 are connected in the end of diode D1, an end of resistance R 3 links to each other with controllable silicon SCR; The other end of controllable silicon SCR links to each other with diode D2, D4, DZ respectively; Diode D2 and diode DZ also are connected in controllable silicon SCR, also are connected on an end of capacitor C 1 simultaneously, and diode D2 connects with valve with electrically motorized operation YM; The end of valve with electrically motorized operation YM links to each other with termination S with diode D3 respectively; The other end of diode DZ joins with the end of resistance R 4 and diode D4 respectively, and the other end of diode D4 links to each other with an end of resistance R 5 and capacitor C 2 respectively, and capacitor C 3 and resistance R 6 are parallelly connected and be connected with resistance R 5 one ends; Also be connected simultaneously with an end of capacitor C 2; The other end of capacitor C 3 and resistance R 6 all is connected with an end of controllable silicon SCR, and the other end of controllable silicon SCR, resistance R 4 and diode D3 all is connected on the termination of tripping coil L, and another termination of capacitor C 2 and tripping coil L joins.
The utility model adopts holding wire and control circuit board control, under the normal operation of circuit breaker, presses pneumatic operating mechanism, makes power connection, tripping mechanism locking this moment, and moving, fixed contact reliably contacts.When prepayment ammeter or remote link provided input signal, the via line element added control voltage to shunt release, and the magnet exciting coil induction is converted into mechanical energy with electromagnetic energy, attracted the iron core motion, promoted release lever, and circuit breaker is broken off; When current overload, the bimetal leaf of overload release produces distortion, and drivening rod promotes snap close, and circuit breaker tripping is broken off; When short circuit current when the electromagnetic system, moving iron core is inhaled, drives push rod, promotes snap close, makes circuit breaker tripping, contact is under the effect of retracting spring and break off completion circuit breaker disjunction protective effect.
This pre-payment circuit breaker; It has shunt release, and overload and break protecting are arranged, and can also carry out far distance controlled disjunction or automatic signal control disjunction to circuit; At present; Be widely used in supporting the making of IC-card pre payment watthour meter and be used for the break-make of control circuit, this circuit breaker meets the IEC60898GB10963GB14048.2 standard, has international most advanced level.
