Abstract
The utility model discloses a porcelain sleeve fixing rack for a high-voltage breaker. The porcelain sleeve fixing rack comprises a fixing frame in a long strip shape. The distance between two sliding racks on the fixing frame is more than the diameter of a porcelain sleeve. Three positioning seats are in sliding fit with the fixing frame. The two ends of each positioning seat are extended out of the two sides of the fixing frame. Installing ears are disposed on the positioning seats. Through holes for passing through the porcelain sleeves are disposed on the positioning seats. Installing base plates are disposed on the positioning seats and around the through holes. Installing holes are distributed on the four corners of each installing base plate. The porcelain sleeve fixing rack with simple and reasonable structure facilitates the installing operation of the porcelain sleeves. When used, the porcelain sleeve fixing rack is installed horizontally on the tops of a group of porcelain sleeves so as to achieve effects of effectively enhancing the stability of the porcelain sleeves, effectively decreasing influences of external force such as vibration on the porcelain sleeves, preventing the porcelain sleeves from loosening or inclining, prolonging the service lives of the porcelain sleeves, and guaranteeing the using security of the high-voltage breaker.
Description
Technical field
The utility model relates to field of circuit breakers, is specially a kind of primary cut-out insulator fixed mount.
Background technology
Primary cut-out is switchgear common in electrical system, its structure mainly comprises operating mechanism, be built-in with the arc control device unit of current transformer and transmission mechanism etc., have minute, closing speed is fast, compact conformation, the break-make that can fast and effeciently control electrical system, is widely used among various high-voltage electric system.And the insulator structure of existing primary cut-out is reasonable not, stability is not good, installs and adjusts inconvenience, easily crooked, easily affected by vibration and loosening after long-time use, and then causes the shortening in useful life of insulator, affects the use safety of primary cut-out.
Utility model content
The purpose of this utility model is to provide a kind of primary cut-out insulator fixed mount, insulator structure with primary cut-out traditional in solution prior art is reasonable not, stability is not good, install and adjust inconvenience, easily crooked, easily affected by vibration and loosening after long-time use, and then cause shorten the useful life of insulator, affect primary cut-out and use safe problem.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of primary cut-out insulator fixed mount, it is characterized in that: include strip fixed frame, spacing between two balladeur trains on described fixed frame is greater than insulator diameter, on described fixed frame, be sliding combined with three positioning seats, fixed frame both sides are stretched out at described positioning seat two ends, and are provided with mounting ear, and described positioning seat is provided with the through hole passing for insulator, on described positioning seat, around through hole, be provided with installation backing plate, four jiaos, described installation backing plate is distributed with installing hole.
Described a kind of primary cut-out insulator fixed mount, is characterized in that: described mounting ear is provided with location hole, in described location hole, is combined with clamping screw.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, facilitated the fitting operation of insulator, during use, fixed mount level is arranged on to the upper end of one group of insulator, can effectively improve the stability of insulator, effectively weakened the impact of the External Force Actings such as vibration on insulator, prevent that insulator from loosening, crooked phenomenon occurring, extended the useful life of insulator, guaranteed the use safety of primary cut-out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
