Abstract
It the utility model is related to a kind of Tiebar structure applied to vacuum on-load operation switch, it is characterized in that, including bolt, upper spring, pull bar, bushing and lower spring, the lower slide of the pull bar in the guide groove of bushing, upper end forms pull bar chamber, the middle part of the pull bar forms lever area, lower spring is installed between the end plate and bushing in lever area, described pull bar intracavitary is provided with spring, the lower end of bolt is stretched into from the top of pull bar chamber, it is spacing by described pull bar chamber with the dynamic cooperation of described upper spring, the bolt.The utility model has the advantages that：The spring of vacuum interrupter is effectively reduced in the elastic damping pulled open with can provided in closing course of vacuum interrupter, pull bar cavity configuration makes the installation more simple and fast of the upper spring and bolt of intracavitary.
Description
Technical field
Sub-connecting switch of transformer field is the utility model is related to, it is specifically a kind of applied to the new of load ratio bridging switch
Type Tiebar structure.
Background technology
Vacuum on-load operation switch can effectively subtract when during using vacuum interrupter using the Tiebar structure
Few structure space, there is provided the reliable excess of stroke, reduce the spring of reset.It greatly strengthen the performance and vacuum of vacuum on-load operation switch
The service life of arc-chutes.
The content of the invention
The defects of to overcome prior art, the utility model provide a kind of pull bar knot applied to vacuum on-load operation switch
Structure.The technical solution of the utility model is：
A kind of Tiebar structure applied to vacuum on-load operation switch, including bolt, upper spring, pull bar, bushing and lower bullet
Spring, the lower slide of the pull bar in the guide groove of bushing, upper end forms pull bar chamber, and the middle part of the pull bar forms thick stick
Bar area, is provided with lower spring between the end plate and bushing in lever area, described pull bar intracavitary is provided with spring, the lower end of bolt
Stretched into from the top of pull bar chamber, it is spacing by described pull bar chamber with the dynamic cooperation of described upper spring, the bolt.
The contact surface of described bolt and pull bar chamber is taper surface.
The latter half of the upper spring is located in the circular groove of pull bar chamber.
The utility model has the advantages that：Have in the elastic damping pulled open with can provided in closing course of vacuum interrupter
Effect reduces the spring of vacuum interrupter, and pull bar cavity configuration makes the installation more simple and fast of the upper spring and bolt of intracavitary.Effectively
The space for saving vacuum on-load operation switch and each interregional insulation distance.
Brief description of the drawings
Fig. 1 is agent structure schematic diagram of the present utility model.
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
The utility model is further described with reference to specific embodiment, and the advantages of the utility model and feature will be with
Description and it is apparent.But these embodiments are only exemplary, do not form any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under without departing from spirit and scope of the present utility model
The details and form of art scheme are modified or replaced, but these modifications and replacement each fall within the scope of protection of the utility model
It is interior.
Referring to Fig. 1 and Fig. 2, a kind of Tiebar structure applied to vacuum on-load operation switch is the utility model is related to, including
Bolt 1, upper spring 2, pull bar 4, bushing 5 and lower spring 8, the guide groove 6 installed in bushing 5 of the lower slide of the pull bar 4
Interior, upper end forms pull bar chamber 3, and the middle part of the pull bar 4 forms lever area 9, is provided with down between the end plate 7 and bushing 5 in lever area 9
Spring 8, spring 2 is installed in described pull bar chamber 3, the lower end of bolt 1 is stretched into from the top of pull bar chamber 3, and described upper
Spring 2 is dynamic to be coordinated, and the bolt 1 is spacing by described pull bar chamber 3.
The contact surface of described bolt 1 and pull bar chamber 3 is taper surface；
The latter half of the upper spring 2 is located in the circular groove of pull bar chamber.
Operation principle of the present utility model：
(1) process is pulled open:There is provided effective pull in lever area lifts pull bar, and the guide groove in bushing provides for pull bar
Slide-and-guide, lower spring provide buffering, lifting process is accurately steadily reduced spring.
(2) closing course：Lever area pulling force disappears, the thrust of lower spring in the self-closing power of vacuum interrupter and bushing
Lower pull bar resets, and the guide groove in bushing provides slide-and-guide, and the upper spring of pull bar intracavitary can effectively make vacuum extinction
Room closes, and reduces spring and ensures contact.Bolt and pull bar intracavitary reserve certain excess of stroke, in the normal of vacuum interrupter
Compensation is provided during scaling loss.
