Abstract
The utility model provides a binding post protective sleeve of an outdoor AC high-voltage vacuum circuit breaker. The protective sleeve comprises a lower folding opening and an insulating outer sleeve for wrapping a binding post electric joint portion. The lower folding opening is provided with a connection portion that enables two sides of the opening to be fixedly connected. The binding post protective sleeve is provided with a port that matches a surface of a binding post insulating column, and the other end of the protective sleeve is a tube-type port for a wire to pass through. According to the technical scheme, the binding post electric joint portion is insulated and protected, thereby effectively preventing the electric joint portion from being eroded by rain, snow, mist and dust, and eliminating safety hidden troubles of electric insulation.
Description
Technical field
The utility model relates to ZW20A-12 type outdoor AC high-voltage vacuum breaker, in particular described vacuum circuit-breaker binding post protector.
Background technology
ZW20A-12 type outdoor AC high-voltage vacuum circuit breaker is in the 50Hz power frequency electric power system, rated voltage is the vacuum circuit-breaker of 12kV; its function is the switchgear as the load current of breaking and making electric power system, overload current, short circuit current etc.; it also can install zero sequence current mutual inductor additional, is grounded defencive function.Lead to respectively inlet wire binding post and outlet binding post on two pairs of sides of this product, each binding post adopts a sulphurated siliastic insulating outer layer, have abundant insulation between the binding post and open distance, guarantee its insulation property, but binding post electric connection part is fully exposed, do not meet the insulating protection requirement, the electric connection part stands the erosion of rain, snow, mist, dust in natural environment, can greatly reduce dielectric strength alternate and over the ground, increase the damage probability of this outdoor AC high-voltage vacuum circuit breaker, shortened useful life.
Summary of the invention
Thereby goal of the invention of the present utility model is to provide a kind of outdoor AC high-voltage vacuum circuit breaker binding post insulating sheath of strengthening the comprehensive raising vacuum circuit-breaker insulated of the dielectric strength barrier propterty of binding post electric connection part.The outdoor AC high-voltage vacuum circuit breaker binding post insulating sheath technical scheme that the utility model provides, its main technical content is: a kind of outdoor AC high-voltage vacuum circuit breaker binding post insulating sheath, this binding post protective jacket is the insulating coating with lower involutory opening, parcel binding post electric connection part, lower involutory opening is provided with the connecting portion that the opening both sides are fixedly connected with, the binding post insulating sheath has the port that coincide with binding post insulated column surface, and the other end is the cast port that electric wire is walked.
The outdoor AC high-voltage vacuum circuit breaker binding post insulating sheath technical scheme that the utility model provides, the pair of wire connection terminals electric connection is partly implemented insulating protection, effectively stop rain, snow, mist, dust to electric connection erosion partly, eliminated the potential safety hazard of electric insulation aspect, its profile is succinct, structure is light and handy, be easy to install, need not any maintenance, its use has prolonged the useful life of vacuum circuit-breaker.
