Abstract
The utility model discloses a load switch, in particular to a sealed vacuum load switch. The utility model adopts the following technology program. A sealed vacuum load switch comprises a stander, a main breaker with a vacuum arc extinguish chamber, a fuse under the main breaker and a isolating switch at the top of the vacuum arc extinguish chamber of the main breaker. The isolating switch is arranged at the right above of the terminal post of the vacuum arc extinguish chamber of the main breaker. The fixed contactor of the isolating switch is arranged with the terminal post of the vacuum arc extinguish chamber as an integration. The moving contactor is connected and disconnected with the contactor on the inclined support of the stander. By using the above program, the utility model overcomes the defect of the existing technology and provides a sealed vacuum load switch of compact structure and small and with isolating switch.
Description
Technical field
The utility model relates to a kind of on-load switch, particularly a kind of Solid-sealing vacuum load switch.
Background technology
Present on-load switch has isolating switch and vacuum interrupter usually, and the main effect of isolating switch (disconnecting link) is an isolation voltage when equipment or line maintenance, to guarantee safety; Vacuum interrupter has another name called vacuum switch tube, and it mainly acts on and is: make behind the mesohigh circuitry cuts power supply blow-out rapidly and suppress electric current by the good insulating properties of vacuum in managing, avoid accident and unexpected the generation.But present isolating switch all is that split is connected with the pole of vacuum interrupter, and this makes that the structure of whole circuit breaker is huge, has influenced the use at special occasions.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned band isolating switch, and the Solid-sealing vacuum load switch of a kind of compact conformation, small and exquisite band isolating switch is provided.
The purpose of this utility model is achieved by the following technical solution: a kind of Solid-sealing vacuum load switch, include frame, the main circuit breaker of band vacuum interrupter, fuse and isolating switch, isolating switch is arranged on the upper end of the vacuum interrupter of main circuit breaker, fuse is arranged on the below of main circuit breaker, described isolating switch is arranged on directly over the pole of vacuum interrupter of main circuit breaker, the fixed contact of isolating switch and the pole of vacuum interrupter are wholely set, the moving contact of isolating switch be arranged on frame on bearing diagonal on contact conducting and disconnect cooperate.
The beneficial effects of the utility model are: the fixed contact of isolating switch and the pole of vacuum interrupter are wholely set and make the more compact structure of whole circuit breaker, profile smaller and more exquisite, thereby satisfy demand widely.
Now in conjunction with the accompanying drawings the utility model is further described:
