Abstract
The invention relates to the field of high-voltage switches, in particular to a five-station disconnecting and earthing switch. The five-station disconnecting and earthing switch comprises a body and a protective device connected with the body. The body comprises a shell, a three-station disconnecting switch and a three-station earthing switch, wherein the three-station disconnecting switch and the three-station earthing switch are assembled in the shell and connected with a conductor. The protective device is a lightning arrester or a voltage transformer, the protective device and the body are connected together through a movable adapter contact and a fixed adapter contact which are arranged on the protective device and the body respectively, and the movable adapter contact is in transmission connection with a driving mechanism used for driving the movable adapter contact to be inserted into or separated from the fixed adapter contact. The protective device can be disconnected from the body through the driving mechanism, it is only needed to insert the movable adapter contact into the fixed adapter contact under driving of the driving mechanism after a withstand voltage test is finished, the protective device can be installed on the body to be transported in ex-factory transportation, and therefore the problems that an existing three-station disconnecting and earthing switch is high in transportation cost and needs to be assembled on site are solved.
Description
Technical field
The present invention relates to high-voltage switch gear field, a kind of five station isolation grounding switchs are especially related to.
Background technology
In recent years, common box type GIS develops rapidly, and three-station isolating grounding switch has tended to ripe, but three stations with
Certain restriction is also existed on the connection of spark gap or voltage transformer.Concrete condition is as follows, and existing three station isolation ground connection are opened
The structure closed is as shown in figure 1, it includes three station grounding switchs 1, tri-station isolating switch 2, static contact isolation switch 3, ground connection
Switch 4, protection device 7（Spark gap or voltage transformer）, it is by transition conductor 5 and contact that protection device is connected with three stations
Seat 6 connection.During On-Site Testing, because protection device is connected and can not isolate with GIS body, can only test after being dismantled,
Deng reinstalling spark gap or voltage transformer after off-test, process moisture, again inflate, therefore typically adopt spark gap or electricity
The mode that pressure transformer individually transports, GIS pressure test is installed after terminating again, which results in cost of transportation, manpower financial capacity
Increasing, especially unloading process also can cause certain potential safety hazard to GIS.
Content of the invention
It is an object of the invention to provide a kind of five station isolation grounding switchs, opened with solving existing three station isolation ground connection
The cost of transportation closing is high and needs site-assembled problem.
In order to solve the above problems, five station isolation grounding switchs of the present invention employ the following technical solutions：Five stations every
From earthed switch, the protection device be connected including body and with body, body includes shell, three stations being assemblied in shell
Disconnecting switch and three station grounding switchs, tri-station isolating switch and three station grounding switchs are connected with conductor, protector
Part is spark gap or voltage transformer, by being divided into switching moving contact on the two, turning between protection device and body
Connect static contact to link together, switching moving contact is connected with and is plugged together and detached drive with switching static contact for ordering about it
Motivation structure.
Described drive mechanism is gear-rack drive mechanism.
Described gear-rack drive mechanism is provided with lockable mechanism.
Described switching moving contact is located on conductor.
Protection device is passed through switching conductor and is connected with body, and described switching static contact is on switching conductor.
Due between the protection device of five station isolation grounding switchs of the present invention and body by being divided on the two
Switching moving contact, switching static contact link together, and moving contact of transferring be connected with for order about its with switching quiet
Contact plugs together and detached drive mechanism, therefore, when installation carries out voltage-withstand test after terminating at the scene, can pass through drive mechanism
Make the activity of switching moving contact and separate with switching static contact, thus protection device is cut off with body, after finishing pressure test, lead to
Overdrive mechanism order about switching moving contact with switching static contact plug together, thus can be in the good transport section of grown place inter-process
Moisture, dispatch from the factory transport when protection device is installed on body transport, thus solving existing three-station isolating grounding switch
Cost of transportation is high and needs site-assembled problem.
Brief description
Fig. 1 is the structural representation of existing three-station isolating grounding switch；
Fig. 2 is the structural representation of five station isolation grounding switchs of the present invention.
Specific embodiment
The embodiment of five station isolation grounding switchs, as shown in Fig. 2 this five station isolation grounding switch include body and
The protection device 11 being connected with body.
Body includes shell 12, the tri-station isolating switch being assemblied in shell 12 and three station grounding switchs, three works
Position disconnecting switch includes disconnecting switch moving contact 13 and static contact isolation switch 14, and three station grounding switchs include earthed switch and move
Contact 15 and static contact of grounding switch 16, tri-station isolating switch and three station grounding switchs are connected with conductor 17, in this enforcement
In example, tri-station isolating switch is to be connected with conductor 17 by static contact isolation switch 14, and three station grounding switchs are by connecing
Ground switch movable contact 15 is connected with conductor 17.
Protection device 11 is spark gap or voltage transformer, by being divided into the two it between protection device 11 and body
On switching moving contact 18, switching static contact 19 link together, switching moving contact 18 be connected with drive mechanism, driving machine
Structure is used for ordering about switching moving contact 18 and is plugged together with switching static contact 19 and separate.In the present embodiment, switching moving contact 18 sets
On conductor 17, body is passed through switching conductor 20 and is connected with protection device 11, and switching static contact 19 is located on switching conductor 20, drives
Motivation structure is gear-rack drive mechanism, and the gear 21 of wherein pinion and rack is assemblied on conductor 17, and tooth bar 22 is assemblied in
On switching moving contact 19 and be connected with turning handle, in order to avoid switching moving contact 18 is plugged together with switching static contact 19 accident,
Gear-rack drive mechanism is additionally provided with lockable mechanism.Locking structure takes bidirectional ratchet control, indicates that handle controls by division
Its direction can not invert thus realizing actuating handle.When to be closed a floodgate, by division instruction handle wrench to " conjunction " position, when actuating handss
When handle goes to certain position, another group of locking structure starts, and realizes actuating handle locked；When being intended to separating brake, division is indicated handss
Handle is pulled to " dividing " position, and bidirectional ratchet realizes counteresteer, and when actuating handle goes to certain position, another group of locking structure opens
Dynamic, realize actuating handle locked.
In the other embodiments of five station isolation grounding switchs, drive mechanism can also adopt turbine and worm mechanism etc..
