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, particularly relate to a kind of five station isolation grounding switchs.
Background technology
In recent years, common box type GIS develop rapidly, three station isolation grounding switchs have tended to ripe, but also there is certain restriction in the connection of three stations and lightning arrester or voltage transformer.Concrete condition is as follows; the structure of existing three station isolation grounding switchs as shown in Figure 1; it comprises three station grounding switchs 1, tri-station isolating switch 2, static contact isolation switch 3, earthed switch 4, protection device 7(lightning arrester or voltage transformer), it is connect by transition conductor 5 and contact base 6 that protection device is connected with three stations.During On-Site Testing; because protection device is connected can not isolates with GIS body; test after can only being dismantled; Deng reinstalling lightning arrester or voltage transformer after off-test, process moisture, again inflate; therefore the general mode adopting lightning arrester or voltage transformer to transport separately; installed after GIS withstand voltage test terminates again, which results in the increasing of cost of transportation, manpower financial capacity, especially unloading process also can cause certain potential safety hazard to GIS.
Summary of the invention
The object of the present invention is to provide a kind of five station isolation grounding switchs, high and need site-assembled problem with the cost of transportation solving existing three station isolation grounding switchs.
In order to solve the problem, five station isolation grounding switchs of the present invention are by the following technical solutions: five station isolation grounding switchs, the protection device comprising body and be connected with body, body comprises shell, be assemblied in the tri-station isolating switch in shell and three station grounding switchs, tri-station isolating switch and three station grounding switchs are connected with conductor, protection device is lightning arrester or voltage transformer, by being divided into the switching moving contact on the two between protection device and body, switching fixed contact links together, switching moving contact is connected with the driving mechanism plugging together for ordering about it with switching fixed contact and be separated.
Described driving 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 connected with body by switching conductor, and described switching fixed contact is located on switching conductor.
Due between the protection device of five station isolation grounding switchs of the present invention and body by being divided into the switching moving contact on the two, switching fixed contact links together, and moving contact of transferring is connected with the driving mechanism plugging together for ordering about it with switching fixed contact and be separated, therefore, when installation carries out voltage-withstand test after terminating at the scene, make switching moving contact movable by driving mechanism and be separated with switching fixed contact, thus protection device and body are cut off, after finishing withstand voltage test, order about switching moving contact by driving mechanism to plug together with switching fixed contact, thus can at the moisture of the good transport section of grown place inter-process, dispatch from the factory transport time protection device be installed on body transport, thus the cost of transportation solving existing three station isolation grounding switchs is high and need site-assembled problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing three station isolation grounding switchs;
Fig. 2 is the structural representation of five station isolation grounding switchs of the present invention.
Embodiment
The embodiment of five station isolation grounding switchs, as shown in Figure 2, the protection device 11 that this five station isolation grounding switch comprises body and is connected with body.
Body comprises shell 12, be assemblied in tri-station isolating switch in shell 12 and three station grounding switchs, tri-station isolating switch comprises isolating switch moving contact 13 and static contact isolation switch 14, three station grounding switchs comprise moving contact of grounding switch 15 and static contact of grounding switch 16, tri-station isolating switch and three station grounding switchs are connected with conductor 17, in the present embodiment, tri-station isolating switch is connected with conductor 17 by static contact isolation switch 14, and three station grounding switchs are connected with conductor 17 by moving contact of grounding switch 15.
Protection device 11 is lightning arrester or voltage transformer; between protection device 11 and body by being divided into the switching moving contact 18 on the two, fixed contact 19 of transferring links together; switching moving contact 18 is connected with driving mechanism, and driving mechanism is used for ordering about switching moving contact 18 and plugs together with switching fixed contact 19 and be separated.In the present embodiment; switching moving contact 18 is located on conductor 17; body is connected with protection device 11 by switching conductor 20; switching fixed contact 19 is located on switching conductor 20; driving mechanism is gear-rack drive mechanism, and wherein the gear 21 of pinion and rack is assemblied on conductor 17, tooth bar 22 be assemblied in switching moving contact 19 on and be connected with turning handle; in order to avoid switching moving contact 18 plugs together with switching fixed contact 19 is unexpected, gear-rack drive mechanism is also provided with lockable mechanism.Locking structure takes bidirectional ratchet to control, and controls its direction thus realize actuating handle to reverse by a deciliter instruction handle.When for closing a floodgate, by deciliter instruction handle wrench to " conjunction " position, when actuating handle forwards certain position to, another group locking structure starts, and realizes actuating handle locked; When for separating brake, by deciliter instruction handle wrench to " dividing " position, bidirectional ratchet realizes counteresteer, and when actuating handle forwards certain position to, another group locking structure starts, and realizes actuating handle locked.
In other embodiment of five station isolation grounding switchs, driving mechanism can also adopt turbine and worm mechanism etc.
