Abstract
The utility model discloses a kind of static contact isolation switch increased the service life at double, the first contact site being engaged including fixed part, for the one pair of which fingertip with disconnecting switch and the second contact site being engaged for another pair fingertip with disconnecting switch, the first contact site and the second contact site are located at the relative two ends of fixed part；The fixed part is in the form of a column, and its side wall is circumferentially spaced to be provided with several stationary planes, and the static contact can be steered the stationary plane rotatable around its axis to switch with the cooperation of its contact base.The utility model can greatly improve the utilization rate of static contact isolation switch, extend the service life of static contact isolation switch at double, and reduce the cost of overhaul, reduce the unnecessary trouble that buying is brought.
Description
Technical field
The utility model is related to a kind of static contact of disconnecting switch, more particularly to it is a kind of increase the service life at double every
From switch static contact.
Background technology
GW31 type disconnecting switch is one of traditional transformer station more conventional disconnecting switch, and the model disconnecting switch is to pass through
The conducting of electric current is realized in 4 fingertips and the contact of static contact, because contact area is small, contact surface is dirty or maintenance craft etc.
Problem frequently results in contact point overheat, so that the static contact of contact portion burns, it is impossible to be further continued for using.But transformer station
The static contact of used GW31 disconnecting switch is that one side is fixed, once contact, which is burnt out, can only re-replace static contact, wherein
It is often a very small part to burn part, therefore the practical efficiency of static contact is very low.Purchasing new stationary contact simultaneously
During head, producer generally will not only sell merely single static contact, may require that a whole set of contact of purchaser's purchase, therefore to spend than quiet
Contact real value has more the fund of decades of times to buy, while process of purchase is also extremely complex.
Therefore propose that a kind of New Type Isolating Switch static contact is imperative, to improve the utilization rate of static contact isolation switch,
The cost of overhaul is reduced, the unnecessary trouble that buying is brought is reduced.
Utility model content
The utility model provides a kind of static contact isolation switch increased the service life at double, which overcomes prior art
Static contact isolation switch present in weak point.
The utility model solves the technical scheme that its technical problem used：A kind of isolation increased the service life at double
Switch static contact, including fixed part, the first contact site for being engaged for the one pair of which fingertip with disconnecting switch and be used for
The second contact site being engaged with another pair fingertip of disconnecting switch, the first contact site and the second contact site are located at fixed part phase
To two ends at；The fixed part is in the form of a column, and its side wall is circumferentially spaced to be provided with several stationary planes, and the static contact can be grasped
The control stationary plane rotatable around its axis to switch with the cooperation of its contact base.
Further, the stationary plane is to face directly.
Further, the quantity of the stationary plane is three, and three stationary planes uniformly divide along the circumferential of the fixed part
Cloth.
Further, the stationary plane is located at the medium position of the fixed part.
Compared to prior art, the utility model has the advantages that：
Several stationary planes are provided with because the side wall of the fixed part is circumferentially spaced, and static contact can be steered around its axle
Line rotates to switch the stationary plane coordinated with its contact base so that when being burnt with the stationary plane that contact base coordinates, and only needs
Rotate static contact, you can a stationary plane and contact base secure fit are reselected in remaining stationary plane, by that analogy, directly
To each stationary plane is finished, therefore, static contact isolation switch compared with prior art, the utility model can greatly improve isolation
The utilization rate of switch static contact, extends the service life of static contact isolation switch at double, and reduces the cost of overhaul, saves buying money
The unnecessary trouble that gold and reduction buying are brought.
The utility model is described in further detail below in conjunction with drawings and Examples；But it is of the present utility model it is a kind of into
The static contact isolation switch increased the service life again is not limited to embodiment.
Brief description of the drawings
Fig. 1 is the front view of static contact of the present utility model；
Fig. 2 is the A-A sectional views of static contact of the present utility model.
Embodiment
Embodiment, is referred to shown in Fig. 1, Fig. 2, and a kind of disconnecting switch increased the service life at double of the present utility model is quiet
Contact, including fixed part 1, the first contact site 2 for being engaged for the one pair of which fingertip with disconnecting switch and for every
The second contact site 3 that another pair fingertip of pass is engaged is left, the first contact site 2 and the second contact site 3 are located at the phase of fixed part 1
To two ends at；The fixed part 1 is in the form of a column, and its side wall is circumferentially spaced to be provided with several stationary planes 11, and the static contact can
It is steered the stationary plane rotatable around its axis to switch with the cooperation of its contact base.
In the present embodiment, the quantity of the stationary plane 11 is three, but is not limited to three.Three stationary planes 11 are along institute
The circumference for stating fixed part 1 is uniformly distributed, and each stationary plane 11 is faced directly.The stationary plane 11 is located at the fixed part 1
Medium position.
Using when, select one of stationary plane of the fixed part 1 and the contact base secure fit of static contact.Once work as
The preceding stationary plane coordinated with contact base burns, and only static contact need to be rotated into 120 °, using in remaining two stationary planes
The contact base secure fit of one of them and static contact (because the area for burning part is very small, therefore, can rotate static contact
The static contact may continue to use after switching stationary plane).Similarly, when second stationary plane coordinated with contact base also burns
When, only static contact need to be rotated 120 ° again, utilize the contact base secure fit of a remaining stationary plane and static contact.This
The utilization rate of static contact is improved 3 times by utility model compared with the static contact isolation switch of prior art, while also prolonging at double
The service life of static contact has been grown, and has reduced the unnecessary trouble that the cost of overhaul and adoption process are brought.
Above-described embodiment is only used for further illustrating a kind of disconnecting switch increased the service life at double of the present utility model
Static contact, but the utility model is not limited to embodiment, it is every according to technical spirit of the present utility model to above example
Any simple modification, equivalent variations and the modification made, each fall within the protection domain of technical solutions of the utility model.
