Description
Technical field:
The utility model relates to secondary distribution system technical field, specifically on-load switch and tri-station isolating switch combination unit.
Background technology:
The system that secondary distribution system is made up of relaying protection, safety automation control, system communication, dispatching automation, DCS automatic control system etc.Electrical secondary system is the indispensable important component part of electric power system, it be realize people and primary system contact supervision, control, make primary system energy safety economy and move.The unification of secondary power distribution equipment is arranged on the inside of an insulation cabinet, in prior art, and the each self-assembly respectively of circuit breaker or on-load switch and tri-station isolating switch, main switch can not assemble separately and debug, and installation accuracy is low, and production efficiency is low.
Utility model content:
Technical problem to be solved in the utility model is to provide one to be convenient to installment and debugging, the on-load switch that installation accuracy and production efficiency are high and tri-station isolating switch combination unit.
This use is novel in order to solve above-mentioned technical problem, adopts following technical scheme:
On-load switch and tri-station isolating switch combination unit, is characterized in that: comprise epoxy pole, bus outlet, vacuum interrupter, pull bar, main shaft, be flexible coupling, fixed contact, moving contact, operating axis, grounding contact and cable cone; Described bus outlet is arranged on the upside of epoxy pole and extends to the inside of epoxy pole, described vacuum interrupter arranges in epoxy pole and is connected with the downside of bus outlet, described pull bar is arranged on the downside of vacuum interrupter, and described main shaft is connected with the lower end of pull bar; Described one end being flexible coupling is connected with the bottom of vacuum interrupter, and one end is connected with the fixed contact that is fixed on epoxy pole inside upper part; Described operating axis is connected with the bottom of pull bar by a connector, described moving contact is arranged on the top of operating axis and is just positioned at the below of fixed contact, described grounding contact is arranged on the inner bottom side of epoxy pole, and described cable cone is arranged on the outside bottom side of epoxy pole.
Described bus outlet and cable cone all adopt standard interface.
Between described moving contact and fixed contact, isolation fracture is greater than 125mm.
Circuit breaker or on-load switch and tri-station isolating switch integrated design.Circuit breaker or on-load switch and tri-station isolating switch are arranged in same epoxy pole, and its operating mechanism is also arranged on and in this pole, has improved assembly precision and production efficiency.
Isolation is three-station with ground connection, possesses ground connection making capability; Isolation fracture and ground connection fracture are all greater than for 125mm; The outlet of major loop bus and cable outlet all adopt standard interface, the independent assortment of a convenient functional unit and adjustment line mode; When serious short trouble appears in major loop chamber, can, by coupled pressure relief channels pressure release, improve Personal Safety;
The beneficial effects of the utility model are: the utility model is simple and reasonable, easy to use, are convenient to installment and debugging, and installation accuracy and production efficiency are high.
