Abstract
The utility model discloses an insulating tie rod of a circuit breaker, which comprises a vacuum arc extinguishing chamber connecting bar, a nut and an insulation part, and is characterized in that the end of the insulation part is fixed with a connecting block tie rod, and the connecting block tie rod which is a screw structure is in threaded connection with a connecting block and is fastened by the fastening nut. By utilizing the structure, the insulating tension tie rod has the advantages of convenient operation without detaching the primary part when adjusting mechanical parameters, increasing production efficiency, bringing convenience to overhaul and maintain the equipment and guaranteeing sound contact of the conductive surfaces.
Description
Technical field
The utility model relates to field of circuit breakers, particularly a kind of insulating pull rod for breaker.
Background technology
Indoor AC high voltage vacuum breaker is as indispensable major control in the electric power system and protection equipment; the reliability height, cut-off that capacity is big, the time between overhauls(TBO) long, pollution-free, no explosion hazard, be fit to series of advantages such as frequent operation, all obtained application more and more widely in every field such as power industry, industrial and mining enterprises, railway transportations.The design of adjustable insulated tension pole and application in the time of can being implemented in the circuit breaker machine debugging, do not need part such as dismount arc-extinguishing chamber just can change the position of insulated tension pole in system, adjust the purpose that overtravel obtains necessary contact pressure to reach.
Traditional insulated tension pole uses fixed pin shaft with being connected of mechanism, and provides contact pressure by the deformation of about 22 dish springs.Use this type insulated tension pole, as adjusting to the breaker mechanic property parameter, just must draw off once part as parts such as vacuum interrupters, repeated disassembled and assembled has influenced production efficiency significantly, good contact to conducting surface simultaneously also has certain negative effect, brings certain obstacle for the organization of production of mass.Simultaneously, the user scene is overhauled circuit breaker or safeguarded also certain difficulty.
When the mechanical property parameter is adjusted, need not dismantle once part, enhance productivity, conveniently equipment being overhauled and safeguards is the problem that prior art need solve.
The utility model content
Technical problem to be solved in the utility model is, a kind of insulating pull rod for breaker is provided, and to reach when the mechanical property parameter is adjusted, need not dismantle once part, enhances productivity, the convenient purpose that equipment is overhauled and safeguards.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of insulating pull rod for breaker, comprise vacuum interrupter connecting rod, nut, insulated part, it is characterized in that: the end of described insulated part is fixed with the contiguous block connecting rod, and the contiguous block connecting rod is a screw-rod structure, be threaded with contiguous block, the locking of employing locking nut by the variation of nut position on the contiguous block connecting rod, thereby realizes dismantling once part realization to the purpose of mechanical property parameter adjustment.
A kind of insulating pull rod for breaker, described insulated part is provided with metal lining, is provided with spring in the metal lining, and spring one end is connected with the metal lining bottom by pad, and the other end fixes by nut and vacuum interrupter connecting rod.
A kind of insulating pull rod for breaker, described vacuum interrupter connecting rod and contiguous block connecting rod are the M12 screw rod.
A kind of insulating pull rod for breaker, described contiguous block connecting rod links to each other with operating mechanism master connecting lever by contiguous block.
A kind of insulating pull rod for breaker, owing to adopt said structure, this device has when the mechanical property parameter is adjusted, and need not dismantle once part, and is easy to operate, enhances productivity; Convenience is overhauled equipment and is safeguarded; Guarantee the advantage of the good contact of conducting surface.
