Description
Technical field
The present invention relates to a kind of rotary three-stations, belong to substation field.
Background technique
Domestic at present, GIS substation of foreign countries generallys use miniaturized products, largely uses three-station structure.It is original
Three-station, the kind of drive of running part multiselect gear, rack-driving or lead screw, nut.The three-station
Structure is complicated, and manufacturing cost is high.
Summary of the invention
The technical problem to be solved by the present invention is to：Solving existing three-station, structure is complicated, manufacturing cost is high
Problem.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of rotary three-station,
It is characterized in that, including switch case, the intracorporal right side of switch housing is equipped with moving contact support, and the intracorporal left side of switch housing is equipped with isolation
Static contact, the intracorporal top of switch housing are equipped with grounding static contact, and the end of moving contact support is equipped with middle conductor, in middle conductor
Equipped with spring touch finger, spring touch finger is connect with the one end for the moving contact that can be rotated around middle conductor, the other end of moving contact
It is fixedly connected with one end of insulated pull rod, the other end of insulated pull rod passes through the front side of switch case.
Preferably, the intermediate ends of the moving contact pass through the connection of middle conductor and grounding static contact or with static contact is isolated
Connection.
Rotary three-station of the invention, compared with original three-station, running part is insulated pull rod
It directly drives coupled moving contact to make rotating motion, eliminates the gear in former three-station drive mechanism, rack gear passes
Dynamic or lead screw, nut the kind of drive, simple and reliable for structure, manufacturing cost is low；The present invention is driven using insulated pull rod and it
Connected moving contact reaches different stations by rotary motion, contacts moving contact with isolation static contact respectively, is quiet with ground connection
Contact realizes the basic operation of three-station, solves the problems, such as that structure is complicated for current three-station, effectively
Reduce the cost of three-station.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of rotary three-station；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The present invention be a kind of rotary three-station, as shown in Figure 1 and Figure 2, by switch case, isolation static contact 1,
Moving contact 2, grounding static contact 3, middle conductor 4, spring touch finger 5, moving contact support 6, insulated pull rod 7 are composed.
The intracorporal right side of switch housing is equipped with moving contact support 6, and the intracorporal left side of switch housing is equipped with isolation static contact 1, switch
The intracorporal top of shell is equipped with grounding static contact 3, and the end of moving contact support 6 is equipped with middle conductor 4, is equipped with bullet in middle conductor 4
Spring fingertip 5, spring touch finger 5 with can connect around one end of moving contact 2 that middle conductor 4 rotates, the other end of moving contact 2 and
One end of insulated pull rod 7 is fixedly connected, and the other end of insulated pull rod 7 passes through the front side of switch case.
The present invention drives moving contact 2 connected to it to make rotating motion by insulated pull rod 7, makes the intermediate ends of moving contact 2
It contacts across middle conductor 4 with isolation static contact 1 or is contacted with grounding static contact 3, complete the basic operation of three-station.
Workflow of the invention is：
Insulated pull rod 7 drives coupled moving contact 2 to make rotating motion, and (is isolated quiet with the static contact of disconnecting switch
Contact 1) contact is at this time disconnecting switch closing position；Insulated pull rod 7 drives coupled moving contact 2 to make rotating motion, with
The static contact (i.e. isolation static contact 1) of disconnecting switch separates, when moving to horizontal plane into 45 degree angles, at this time for disconnecting switch with
The common open position of earthing switch；Insulated pull rod 7 drives coupled moving contact 2 to make rotating motion, and moves to and is grounded
Static contact 3 contacts, and is at this time earthing switch closing position.
