Specific embodiment
This utility model embodiment will be described in further detail below.
40.5kV earthed switches with independent operation mechanism of the present utility model, its preferably specific embodiment is：
Be welded including gas tank, the gas tank be welded in be provided with ground connection earthed switch, the earthed switch is by yoke plate and dynamic
Sealing is connected with ground connection operating mechanism.
The earthed switch includes earthing portion dress, grounding static contact component, and the both sides of the grounding static contact component set
There is grading ring.
The ground connection operating mechanism is welded including main shaft, and the main shaft is welded and is connected with spring and spring conductor rod, described
The handle hole position that main shaft is welded is provided with gear hole piece.
Direction board is mounted with the ground connection operating mechanism, the direction board is connected with the dynamic sealing.
40.5kV earthed switches with independent operation mechanism of the present utility model, connect for 40.5kV circuits are specially designed
Ground switch and its operating mechanism, and make them simpler in structure, it is more reliable, it is more economical, can preferably ensure high-tension line
Reliable ground and maintainer safety；The adjustment for solving the position divided, close a floodgate of general earthed switch is inconvenient, adjusts
Whole more difficult problem；Solve, because the meeting that grounding static contact components are difficult to avoid that has wedge angle, to cause around it
Electric field is uneven, easily causes the problem of point discharge；In operation bore portion machine for casing-in or applying cover to book tool interlock, it is to avoid to earthed switch
Maloperation so as to more install reliable；Solve earthed switch point, combined floodgate indication problem, and make its indicate function more may be used
Lean on.The reliable ground of 40.5kV high-tension lines can be realized, it is ensured that the safety in service work, and make that equipment is simple, reliability, Jing
Ji.
Specific embodiment：
As shown in Figure 1 a, 1 b, this scheme is connecing in this utility model to the straight-through cabinet overall technical architecture of 40.5kV cables
Ground switch and its an instantiation of operating mechanism application.
Earthed switch point, combined floodgate motion principle：
When operation axis, spring compressed energy-storage under the driving of the connecting lever being welded on main shaft, while being arranged on mechanism
Connecting lever below, by connecting plate, dynamic sealing earthing motion, after main shaft turns over dead point, the spring wink now compressed are driven
Between discharge, close earthed switch, and the height of bolt that can be by adjustment on the spacing bearing led to limit to be welded
The angle of the block on axle reaches preferable closing position making earthing.Separating brake is moved in the same manner.
The structure of earthed switch as shown in Fig. 2 a, Fig. 2 b, structure such as Fig. 3 a of operating mechanism, Fig. 3 b, Fig. 4 a, Fig. 4 b institutes
Show, block 23 is welded on main shaft, main shaft connecting lever 24 is welded on main shaft.
The overall structure of this earthed switch and its operating mechanism is very simple.It is relatively reliable because driving-chain is very short,
Parts are little and all easy to process therefore more economical.
Operating mechanism only needs the height of the bolt by adjustment on spacing bearing, so that it may easily adjust earthed switch
Point, close a floodgate position, implement very convenient.
Due to the presence wedge angle that grounding static contact components are difficult to avoid that, cause its surrounding electric field uneven, easily cause
Point discharge, is that we design in grounding static contact components and are mounted with grading ring 9 this, is so meeting insulating requirements
On the premise of, the well uniform electric field of grounding static contact components, it is to avoid point discharge.
Mechanical interlocks gear hole piece 15 is also designed and has installed additional in operation bore portion, this keeps off hole piece by spring reset, and
Padlock can be installed, under normal circumstances, gear hole piece blocks handle hole, and prevention carries out operating to operating mechanism, only when need
When wanting, padlock is removed, and push gear hole piece open to the left, mechanism could be operated, so avoid what is switched with docking
Maloperation so as to more safe and reliable.
In order to preferably react the splitting or integrating gate position of earthed switch, also design and be mounted with to refer on ground connection operating mechanism
Show board 16, and direction board is arranged in the dynamic sealing being directly connected with earthing main shaft, so makes it indicate that function more may be used
Lean on.The reliable ground of high-tension line and the safety of maintainer can well be ensured.
The beneficial effect that technical solutions of the utility model are brought：
1st, this utility model is for the specially designed earthed switch of 40.5kV circuits and its operating mechanism, this earthed switch
It is more reliable and its operating mechanism is simpler in its structure, it is more economical, can well ensure reliable ground and the inspection of high-tension line
Repair the safety of personnel.
2nd, the operating mechanism of this utility model only needs the height of the bolt by adjustment on spacing bearing, so that it may adjust
The position divided, close a floodgate of whole earthed switch, implements very convenient.
3rd, grading ring is designed and is mounted with grounding static contact components, so meeting the premise of insulating requirements
Under, the well uniform electric field of grounding static contact components, it is to avoid point discharge thus can be by the size of gas tank
That what is done is less, reduces manufacturing cost.
4th, mechanical interlocks gear hole piece has been installed additional in operation bore portion, it is to avoid maloperation to earthed switch so as to
More install reliable.
5th, direction board is also mounted with ground connection operating mechanism, and direction board is arranged on and is directly connected with earthing main shaft
Dynamic sealing on, make instruction function relatively reliable.This design can well ensure reliable ground and the maintainer of high-tension line
Safety.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
This is confined to, any those familiar with the art can readily occur in the technical scope that this utility model is disclosed
Change or replacement, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
