Description
Technical field
The invention belongs to electric secondary circuit technical field, especially relates to the anti-jump control loop of a kind of 10kV switch cubicle.
Background technology
Anti-jump loop is secondary circuit conventional in electrical system, can prevent the combined floodgate contact because of control switch or automatics from failing to return (the non-release handle of such as operating personnel in time, the combined floodgate contact adhesion of automatics) and just in time close a floodgate on faulty line and equipment, cause circuit breaker to close continuously and cut phenomenon.Electric trip-preventing loop for current start, voltage freeze mode also has a critical function, prevents circuit breaker auxiliary contact adjustment improper (conjugate slow) because of trip(ping) circuit exactly, causes the elder generation's current interruption of protection exit contact and the phenomenon of burning.This phenomenon is intolerable for microcomputer protecting device, and this point is often ignored by people.Conventional anti-jump loop has tandem anti-jump loop, parallel anti-jump loop, spring energy-storage anti-jump loop, breaking coil auxiliary contact formula anti-jump loop etc.Domestic circuit breaker many employings tandem anti-jump loop; wherein tandem anti-jump loop is the most reasonable, and application is also the most extensive, and it is except having anti-bouncing function; also have and prevent the current interruption of protection exit contact and the advantage of burning, this is also the indispensable technical conditions of application microcomputer protecting device.Other anti-jump loops only have the function preventing circuit breaker from jumping, and breaking coil auxiliary contact formula anti-jump loop is when performing anti-bouncing function, and breaking coil is charged for a long time likely to be burnt.
