Abstract
The utility model discloses a spring operating mechanism for an indoor high-voltage vacuum circuit breaker, which is used for closing and dividing a switch for the operation of an electric network in an electric power system. The left side of an energy storing shaft is hung and sheathed with an energy storing spring, the energy required by the mechanism is ensured, the fatigue strength of the spring and the size of space occupied by the spring are reduced. The operating mechanism for an indoor high-voltage vacuum circuit breaker has the advantages of compact structure, small size, low cost, convenient assemblage and perfect function, integrated solid sealed poles can be assembled, an insulating cylinder can be also arranged and packaged products in electric industries can be miniaturized.
Description
Technical field:
The utility model relates to a kind of indoor high-voltage vacuum circuit breaker, and is special relevant with the spring operating mechanism of indoor high-voltage vacuum.
Background technology:
The 12kV indoor high-voltage vacuum circuit breaker is that the electric power system operation of power networks is closed, the visual plant of sub-switching operation, its performance directly has influence on fail safe, reliability and the quality of power supply of electric power networks, and ensures that the critical function unit of circuit breaker characteristic is exactly its operating mechanism.Along with prepackage sell of one's property product are convenient to install, need not build a house, save the appearance of advantages such as floor space, the product that those volumes are bigger trends towards the miniaturization development gradually; 12kV vacuum circuit-breaker operating mechanism kind is more in the market, and as CT17, CT19 etc., these operating mechanism overall dimensions are bigger.
Summary of the invention:
The utility model is at the bigger problem of the integrated vacuum circuit-breaker overall dimension of 12kV electric pressure mechanism on the market, designs a kind of rational in infrastructure, miniaturization indoor high-voltage vacuum circuit breaker spring operating mechanism.
The technical solution adopted in the utility model is: energy-stored spring adopts the two-man act of one-sided hanging sleeve dress, has promptly guaranteed the energy that mechanism is required, has reduced the fatigue strength and the spring occupation space size of spring again.
The indoor high-voltage vacuum circuit breaker spring operating mechanism compact conformation that the utility model provides, volume is little, with original product versatility height, technical maturity is convenient to tissue production, can be equipped with integrated pole as required, also can adopt the insulating cylinder mounting means, easy to assembly, perfect in shape and function has promoted the development of electric utility complete sets of products miniaturization; Reduce cost, also saved resource simultaneously.
