Description
Technical field
This utility model relates to 10KV distribution switchgear, belongs to electrical equipment technical field, and i.e. a kind of solid insulation is high
Pressure vacuum distribution switchgear.
Background technology
Along with the development of power construction, electrical network is constantly expanding, and capacity is also being continuously increased.Solid insulation high pressure vacuum is joined
Electric switching system is a kind of equipment that in equipment for power transmission and distribution, usage amount is more, and its version is various, the occasion installed and used
Also it is not quite similar, in power distribution actual motion, it is necessary to follow strictly: when disconnecting switch is when closing a floodgate, and earthed switch must divide
Lock, disconnecting switch is when gate-dividing state, and earthed switch can carry out the operation closed.And keep apart in controller switching equipment structure
Close, earthed switch is separately to install, and is easily caused maloperation.Once maloperation is easily caused owing to there is electric current on circuit, special
Be not electric current bigger time, and cause beat arc, occur security incident.
Summary of the invention
It is separately to install to solve in background technology disconnecting switch, earthed switch in existing controller switching equipment structure, holds
The shortcoming being easily caused maloperation so that the effect that product had the most not only been reduced investment outlay but also safety can be run, durable is suitable for, and uses
Scope is wide, and this utility model provides the new design of a kind of solid insulation high pressure vacuum distribution switchgear.
This solid insulation high pressure vacuum distribution switchgear, the disconnecting switch including framework and being fixed on framework,
On-load switch, earthed switch, it is characterised in that described disconnecting switch includes isolating axle, isolation connecting lever, and isolation axle passes through linking arm
Being hinged with isolation connecting lever, described earthed switch includes grounding shaft and earthed crank arm, is hinged between them, and linking arm is also and grounding shaft
Being hinged, described isolation axle and framework are fixing to be connected, be provided with between described isolation axle and grounding shaft isolate connecting lever, earthed crank arm and
Linking arm, isolation connecting lever and earthed crank arm respectively with isolation axle and grounding shaft is connected, the two ends of linking arm respectively with isolate axle with
And grounding shaft is hinged.
Described earthed crank arm lower end connects insulated tension pole, and described insulated tension pole is sequentially provided with static contact, vacuum from top to bottom
Arc-chutes, bus casing；Described bus casing is positioned at the underface of vacuum interrupter；Described on-load switch is provided with insulating boot,
Being connected together by bus casing and be arranged on base, motor drive mechanism is coupled by operation axle.
When by isolated operation hole, operating axle, turn left, drive isolation axle, isolation connecting lever action, now disconnecting switch
Close a floodgate, drive linking arm grounding shaft and earthed crank arm to link successively, now grounding switch tripping simultaneously.Described isolation axle and ground connection
Axle link, and disconnecting switch and earthed switch opening and closing state contrary.
The beneficial effects of the utility model are, disconnecting switch and earthed switch linkage, disconnecting switch is closed a floodgate when, connect
Ground switch separating brake, disconnecting switch separating brake when, earthed switch closes a floodgate, it is possible to realizing anti-misoperation, on-load switch is provided with
Insulating boot improves the safety index of operator.Utilize the space in high-tension switch cabinet fully, make electrical equipment in high-tension switch cabinet
The configuration of element is compacter.
