Description
Technical field
This utility model relates to a kind of middle pressure vacuum circuit breaker carrying preventer, belongs to vacuum circuit breaker technology neck
Territory.
Background technology
" vacuum circuit breaker " because of after its arc-extinguishing medium and arc extinguishing the dielectric of contact gap be all fine vacuum and gain the name；Its
Have that volume is little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, apply the most universal in power distribution network.Very
Empty chopper is 3～10kV, and the indoor distribution in 50Hz three-phase alternating current system is available for industrial and mining establishment, power plant, transformer station
The middle protection as electric equipment and control are used, and be particularly well-suited to requirement non-oil ultra high vacuum system, few maintenance and frequent operation makes use
Institute, chopper is configurable in middle-placed switch cabinet, double-layer cabinet, fixing cabinet as controlling and protection high voltage electric equipment use.
The most common failure of vacuum circuit breaker mainly divides electric loop fault and two aspects of mechanical breakdown.Mainly show themselves in that
The gas leakage of vacuum interrupter, insulation fault, tripping and maloperation, divide-shut brake not same period etc..
The pole insulation of vacuum circuit breaker experienced by air insulation-meet insulation-sealing and insulate.Although the third generation insulate
(pole) improves against weather, but major part vacuum circuit breaker or the second filial generation meets insulation, by extraneous ring at present
Border impact is bigger.It is aging that the heat produced in operation and power plant's stress all can make insulation produce.The running environment of vacuum circuit breaker,
Such as dust, moisture etc. are bigger on equipment impact.
Therefore, it is necessary to vacuum circuit breaker is improved, to reduce or to prevent fault from occurring.
Utility model content
This utility model mainly solving the technical problems that provide a kind of be affected by the external environment little, reduce the carrying of fault
The middle pressure vacuum circuit breaker of preventer.
This utility model provides a kind of middle pressure vacuum circuit breaker carrying preventer, described in carry in preventer
Pressure vacuum circuit breaker includes middle pressure vacuum circuit breaker main and preventer main body；Medium pressure vacuum circuit breaker main is installed on
In preventer main body；Described preventer main body includes protective cover and base；Described protective cover be shaped as inverted U-shaped,
The side of protective cover is movably connected with the base by hinge, and the opposite side of protective cover is connected by snap close and base are fixing.
In a kind of embodiment of the present utility model, described base is two I-shape constructions, two I-shape constructions
Lower end seamless link.
In a kind of embodiment of the present utility model, medium pressure vacuum circuit breaker main and the lower end of I-shape construction
Fixed installation.
In a kind of embodiment of the present utility model, the inside of described protective cover is provided with reinforcement, is used for preventing protection
Cover shake.
In a kind of embodiment of the present utility model, the middle part of described I-shaped structure with one or more hole,
The connection line of middle pressure vacuum circuit breaker main can be attached with outside by this some holes.
In a kind of embodiment of the present utility model, the hole wall in described hole contains sealing gasket.
In a kind of embodiment of the present utility model, described protective cover is transparent material, can directly be seen by protective cover
Operation conditions to middle pressure vacuum circuit breaker main.
