Abstract
The utility model discloses a kind of rotary three-stations, it is characterized in that, including switch case, the intracorporal right side of switch housing is equipped with moving contact support, the intracorporal left side of switch housing is equipped with isolation static contact, the intracorporal top of switch housing is equipped with grounding static contact, the end of moving contact support is equipped with middle conductor, spring touch finger is equipped in middle conductor, 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 is fixedly connected with one end of insulated pull rod, and the other end of insulated pull rod passes through the front side of switch case.The utility model is of simple structure and low cost, different stations is reached by rotary motion with moving contact using insulated pull rod, moving contact is set to contact with isolation static contact, contact respectively with grounding static contact, realize the basic operation of three-station, it solves the problems, such as that structure is complicated for current three-station, significantly reduces the cost of three-station.
Description
Technical field
The utility model relates to a kind of rotary three-stations, belong to substation field.
Background technique
Domestic at present, GIS substation, 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
Technical problem to be solved by the utility model is: solving existing three-station, structure is complicated, manufacturing cost
High problem.
In order to solve the above-mentioned technical problem, there is provided a kind of rotary three stations to open for the technical solution of the utility model
It closes, which 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 set
There is isolation static contact, the intracorporal top of switch housing is equipped with grounding static contact, and the end of moving contact support is equipped with middle conductor, intermediate
Spring touch finger is equipped in conductor, spring touch finger is connect with the one end for the moving contact that can be rotated around middle conductor, moving contact
The other end is fixedly connected with one end of insulated pull rod, and 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.
The rotary three-station of the utility model, compared with original three-station, running part is insulation
Pull rod directly drives coupled moving contact to make rotating motion, and eliminates gear, tooth in former three-station drive mechanism
The kind of drive of item transmission or lead screw, nut, simple and reliable for structure, manufacturing cost is low；The utility model utilizes insulated pull rod
Coupled moving contact is driven to reach different stations by rotary motion, contact moving contact with isolation static contact respectively,
It is contacted with grounding static contact, realizes the basic operation of three-station, solve that current three-station is complicated to ask
Topic, significantly reduces 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
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The utility model is a kind of rotary three-station, as shown in Figure 1 and Figure 2, by switch case, isolation stationary contact
First 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 utility model drives moving contact 2 connected to it to make rotating motion by insulated pull rod 7, makes in moving contact 2
Between end contact or contacted with grounding static contact 3 with static contact 1 is isolated across middle conductor 4, complete the basic behaviour of three-station
Make.
The workflow of the utility model are as follows:
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.
