Abstract
The utility model provides a secondary protective shield of outdoor high-voltage vacuum breaker, being arranged on one side of the box body of the operating mechanism of a vacuum circuit breaker body. The secondary protective shield of outdoor high-voltage vacuum breaker is provided with a secondary protective control wiring box which is fixed on the box body of an operating mechanism; the inside of the wiring box is provided with a secondary wiring terminal block, a secondary transformation ratio transfer switch, an electronic surge suppressor and a secondary protective shield; the outside of the wiring box is provided with an operating pull ring which is connected with the switch of the secondary protective shield. The secondary protective shield of outdoor high-voltage vacuum breaker is used for the shielding of the secondary protection of an outdoor high voltage vacuum breaker; when the shielding and protective functions of the vacuum circuit breaker is required, power outage is not required, and the housing and the closing plate of the box body of the operating mechanism are not required to be opened to dismount and reconnect a secondary protective wire; the adjustment can be completed by common electricians, and specialized technical personnel are not required. The secondary protective shieldof outdoor high-voltage vacuum breaker has the advantages of power outage free, easy operation and direct viewing.
Description
Technical field
The utility model relates to the electric switch technical field, especially relates to the electric switchgear that outdoor high-voltage vacuum breaker in the power circuit shields secondary protection function fast.
Background technology
The second protection circuit of the outdoor high-voltage vacuum breaker of present domestic use all is contained in the operating mechanism casing of vacuum circuit-breaker; when a certain section distribution line do not need the vacuum circuit-breaker protection; will shield the defencive function of vacuum circuit-breaker so; normally way is first power failure; the case or the shrouding of opening operation mechanism casing again, with instrument to the second protection line dismantle, reclosing, it is very loaded down with trivial details to operate; interruption duration is long, and must be adjusted by the professional.
Summary of the invention
The purpose of this utility model is for solving the difficult problem of above-mentioned second protection thread-changing, and a kind of second protection screening arrangement of outdoor high-voltage vacuum breaker is provided, and only needs the mask switch of this device of actuating, can realize the shielding of vacuum circuit-breaker second protection or open-minded.
The purpose of this utility model is achieved in that on the basis of existing outdoor high-voltage vacuum breaker; the second protection line is shifted out in the operating mechanism casing; be loaded in the ad hoc secondary control junction box; be equiped with secondary connection terminal board, secondary no-load voltage ratio change over switch in the case; electronics surge damper and second protection mask switch are equipped with the operation draw ring on the second protection mask switch.
In the time need masking to the defencive function of vacuum circuit-breaker, only need will operate draw ring and upwards shift onto and get final product with the insulation hook stick, when needing protection, will operate draw ring and pull down to put in place and get final product.
Owing to adopted technique scheme; when needs during to vacuum circuit-breaker shielding protection function; need not to have a power failure; need not the case and the shrouding of opening operation mechanism casing; remove dismounting, reclosing second protection line, also needn't operate, can conveniently realize the purpose of adjusting with general electrician personnel by the professional and technical personnel; do not have need have a power failure, easy and simple to handle, characteristics intuitively.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, vacuum circuit breaker main; 2, secondary connection terminal board; 3, secondary no-load voltage ratio change over switch; 4, electronics surge damper; 5, second protection mask switch; 6, second protection control junction box 7, operation draw ring.
Embodiment
