Description
Technical field
The utility model belongs to the high voltage power distribution technical field, relates to a kind of permanent magnetic vacuum breaker, the side-mounted permanent magnetic vacuum breaker of especially a kind of monostable.
Background technology
Vacuum circuit-breaker, by English, U.S. research, develops into the other countries such as Japan, Germany and the former Soviet Union at first subsequently.China is from the nineteen fifty-nine vacuum circuit-breaker theory that begins one's study, and formally produces all kinds of vacuum circuit-breakers to early 1970s.Along with the manufacturing technologies such as vacuum interrupter, operating mechanism, insulation level are constantly brought forth new ideas and improve, make the development of vacuum circuit-breaker very rapid, obtaining a series of great achievements aspect large capacity, miniaturization, intellectuality and reliability consideration.
The ZNlO0-12/D630-20 vacuum circuit-breaker adopts spring operating mechanism, mounting means is flip-over type, the ZNlO0-12 vacuum circuit-breaker is to possess good arc quenching characteristic, electrical endurance is long, operational reliability is high, long advantage of time between overhauls(TBO) not, at the net transformation of current China's electric power town and country state, chemical industry, metallurgy, railway is electric and the industry such as mine is widely used.But because the mechanical endurance of spring mechanism is short, spring mechanical is tired, mechanical connection is unreliable, its upside-down mounting mode can't access isolating switch in addition, therefore its scope of application is restricted.How the deficiency of complete high-pressure vacuum breaker in practical application, become a technical problem to be solved.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of monostable side-mounted permanent magnetic vacuum breaker, this permanent magnetic vacuum breaker is when keeping existing vacuum circuit-breaker technical advantage and improving the prior art parameter, can solve that mechanical endurance is short, spring mechanical is tired, mechanical connection is unreliable, upper isolating switch such as can't install at the problem, and is applicable more extensive.
The purpose of this utility model solves by the following technical programs:
The side-mounted permanent magnetic vacuum breaker of this kind monostable, the pole mounting seat that comprises the permanent magnet mechanism chamber and be arranged on permanent magnet mechanism chamber side and with it, be communicated with, at the indoor permanent magnet mechanism that is provided with of described permanent magnet mechanism, the permanent magnet mechanism pull bar of described permanent magnet mechanism lower end is flexibly connected by link gear and the mechanism rod that is arranged in the pole mounting seat; On described pole mounting seat, a plurality of poles are installed, the lower end insulated tension pole of pole stretches in the pole mounting seat and with described mechanism rod, by connector, is connected.
Above-mentioned permanent magnet mechanism inside is equiped with the divide-shut brake coil, and coil is connected to output place of permanent magnet mechanism controller power supply.
Above-mentioned link gear comprises L-type link gear plate and the permanent magnet mechanism axis of guide; Be installed with two connecting plates by spline on the described permanent magnet mechanism axis of guide, the outer end of one of them connecting plate is connected with the lower end axle of described permanent magnet mechanism pull bar, another connecting plate is flexibly connected by an end of connector and L-type link gear plate, and the other end of L-type link gear plate and described mechanism rod are flexibly connected.
On the said mechanism connecting rod, tripping spring is installed.
The utlity model has following beneficial effect:
Monostable permanent magnetic vacuum breaker employing Monostable permanent magnetic mechanism of the present utility model, not only improved mechanical endurance but also its machine components are few, reliable in action; Again because it is to keep circuit breaker position by permanent magnet, so there are not the problems such as spring mechanical fatigue.The monostable permanent magnetic vacuum breaker adopts the pole type vacuum pipe simultaneously, effectively raises the insulating capacity of circuit breaker.
Above-mentioned breaker mechanism is simple, and is rationally distributed.Vacuum interrupter is vertically installed and is become word order with mechanism, and vacuum tube seals with pole inner admittedly,, even under rugged environment, still can keep very high creepage performance and insulation property; Its without the blast, pollution-free, noise is low, volume is little, lightweight, the life-span is long.
