Abstract
Pulse controller is in use for controlling power supply of breaker in equipment for distributing electric power. Circuits of the pulse controller are as following: passing through rectification, electric supply is divided into two routes; one route of supplying electromagnetic coil of breaker passes through circuit of monitoring coil operation; passing through power transfer circuit including circuit of step down the voltage, filter etc, another route passes through circuit of monitoring operational power supply to supply voltage comparator circuit, and monostable circuit as well as circuit for monitoring impulse for switching on or off. In each time of switching on/off, monostable circuit generates a pulse in 50ms to trigger field effect transistor to on so as to supply power for magnet coil of breaker in order to switch on/off reliably. The invention prevents overlong time of switching breaker on/off as well as monitors and indicates pulses and procedure for electrifying coil.
Description
Technical field
The present invention relates to the electric switch technical field, especially relate to the control device of circuit breaker power supply.
Background technology
In electric power system, circuit breaker is widely used as power distribution equipment, and circuit breaker generally is by the charged adhesive of solenoid, and the lead agency transmission comes deciliter power circuit, thereby reaches the purpose of power distribution; Yet following situation in use takes place through regular meeting in present circuit breaker: the one, because of breaker mechanism moves dumb, appearance is got stuck or the auxiliary contact adhesion causes the circuit breaker branch, it is unsuccessful to close a floodgate, if operating personnel carry out branch, combined floodgate for a long time, will burn out coil; The 2nd, because of auxiliary contact adhesion meeting cause branch, close, divide, close ... jump over phenomenon, the stability that this will greatly damage power equipment and destroy electric power system; The 3rd, under the situation that appearance can not divide, close a floodgate, search reason and get entirely by rule of thumb, waste time and energy, there are not special inspection means.
Summary of the invention
The objective of the invention is easily to burn coil and initiating system and problem such as occur jumping over, a kind of power supply pulse controller of breaker is provided, also make it to have fault diagnosis functions simultaneously, fix a breakdown to make things convenient for the user for solving above-mentioned circuit breaker.
For achieving the above object, technical scheme of the present invention is such: a kind of power supply pulse controller of breaker, have separating brake control and combined floodgate controlled function, comprise branch or combined floodgate switch, power rectifier circuit, gate-controlled switch, branch or closing coil, coil working monitoring circuit, integrated circuit working power translation circuit, working power monitoring circuit, voltage comparator circuit, monostable circuit, branch or closing pulse monitoring circuit; Civil power is through power rectifier circuit, and one the tunnel connects gate-controlled switch, for branch or closing coil, and coils work monitoring circuit; One the tunnel through power converting circuit, and through the working power monitoring circuit, voltage supplied comparison circuit and monostable circuit; Wherein voltage comparator circuit is made up of voltage comparator and branch or switching voltage sample circuit and reference voltage circuit; Monostable circuit adopts monostable wave mode generator, and through dividing or the closing pulse monitoring circuit; Monostable circuit outputs signal to gate-controlled switch, starts gate-controlled switch and realizes dividing or closing operation; In coil working monitoring circuit, working power monitoring circuit, branch or closing pulse monitoring circuit, be respectively equipped with light-emitting diode; Monostable circuit is worked as working power just often, in the pulse that divides or the moment of closing a floodgate produces a 50ms; Reference voltage through sampling branch or power switch voltage and setting in the voltage comparator circuit compares, when being higher than the reference voltage of setting, allow monostable wave mode generator to start, when being lower than the reference voltage of setting, then reset, can close or sub-gate signal output under the improper voltage of locking like this; And by light-emitting diode power supply and branch, closing pulse and coil electricity are finished three key points and monitor and indicate.
Owing to adopted technique scheme, a kind of power supply pulse controller of breaker of the present invention has following beneficial effect: the one, minute, to close a floodgate be a 50ms pulse, thoroughly changed traditional branch, closing a floodgate burns out the phenomenon of coil because of overlong time; Simultaneously also fundamentally eliminated the circuit breaker branch, close, divide, close ... jump over phenomenon; The 2nd, increased supervision and deixis, comprise indication and supervision that power supply, branch, closing pulse, coil electricity are finished, effective inspection means are provided for fixing a breakdown.
