Technical field
This utility model relates to state monitoring system for circuit breaker, belongs to low-voltage distribution or low voltage control field.
Background technology
Primary cut-out effect is: one is control action, i.e. according to the needs of operation of power networks, by partial electric equipment or
Circuit puts into or out of service；Two is protective effect, i.e. when electrical equipment or power circuit break down, relay protection or from
Dynamic device sends trip signal, makes chopper disconnect, and faulty equipment or circuit is excised rapidly from electrical network, it is ensured that nothing in electrical network
Faulty component properly functioning, chopper success cut-offs required electric parameter and is through mechanical property parameter and controls
System, and overtravel is exactly a critically important mechanical property parameter.Overtravel be contacts of vacuum switch of completely closed after, dynamic touch
Head or the mobile distance of static contact.The effect of overtravel mainly have following some: 1. ensure contact remain to after electrical wear
Keep certain contact pressure；2. touch spring power can be utilized during contact closure to buffer, reduce spring；3. when contact separating brake,
Make moving contact obtain certain initial kinetic energy, break melting welding point, improve initial opening velocity, reduce the arc time, thus improve
The speed of medium recovery.
If overtravel is the least, contact due contact pressure after scaling loss cannot be ensured, so may result in disconnected
Road device cisco unity malfunction；Meanwhile, initial opening velocity diminishes, and can affect breaking and making and the dynamic thermal stability of vacuum switch
Can, even produce reclosing springing.If overtravel is too big, can increase the combined floodgate power of operating mechanism, making combined floodgate become pole can not
Leaning on, therefore, it is the most necessary for monitoring the overtravel of chopper in real time.
