Abstract
The utility model relates to an outdoor vacuum high voltage circuit breaker which is utilized in overload protection of the power line, especially the breaker can adjust the second-time protection value quickly when the power load of the power line leaping or reducing drastically; based on the present outdoor vacuum high voltage breaker, the utility model transfers the second-time protection circuit device from the operation chamber to another proper second-time wiring protection chamber, the chamber is fixed and connected to the side of the operation mechanism chamber; a binding post row, transfer switch, and electronic elimination gushing are arranged in the second-time wiring protection chamber. A secondary current indication board is arranged around the handle of the transfer switch. When the second-time protection parameter of the vacuum breaker going to be modulated, the operation carried out is that only rotating the handle of the current transition switch which increase the secondary current to the required value, the operation is simple and direct, and the cut-off time is short.
Description
Technical field
The utility model relates to the protective overload circuit-breakin technical field, especially relates to the outdoor high-voltage vacuum breaker that can fast adjust circuit breaker second protection numerical value when power circuit increases severely because of power load or reduces sharply.
Background technology
The second protection line unit of the outdoor high-voltage vacuum breaker of present domestic use; all be assemblied in the operating mechanism casing of circuit breaker; increase severely because of power load or reduce sharply when power circuit takes place; when needing to adjust the second protection numerical value of circuit breaker; must open the case or the shrouding of operating mechanism casing, with instrument to the second protection line dismantle, reclosing adjusts, 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 to adjust difficult problem at above-mentioned second protection circuit; and a kind of novel outdoor high-voltage vacuum circuit-breaker that provides; it can need not dismounting, reclosing second protection line; also needn't non-ly operate by the professional and technical personnel; can conveniently realize the purpose adjusted with general personnel; have easy and simple to handle, directly perceived, the characteristics that interruption duration is short.
The purpose of this utility model is achieved in that on the basis of existing outdoor high-voltage vacuum breaker, the second protection line unit is shifted out in the operating mechanism casing, in the second protection junction box who establishes along for accommodation into other, this junction box is fixedly connected on operating mechanism casing one side; Front the second protection junction box has door, is provided with secondary connection terminal board, second protection change over switch and electronics surge damper in the door; Around the handle of second protection change over switch, be provided with the secondary current direction board.
In the time need adjusting to the second protection setup parameter of vacuum circuit-breaker, only need open second protection wiring chamber door, directly the handle of rotatory current change over switch transfers to needed size with the second protection electric current and gets final product.
Owing to adopted technique scheme; when the second protection setup parameter is adjusted; need not to open the case or the shrouding of operating mechanism casing; remove dismounting, reclosing second protection line; also needn't non-ly operate by the professional and technical personnel; can conveniently realize the purpose adjusted with general personnel, have easy and simple to handle, directly perceived, the characteristics that interruption duration is short.
