Description
Technical field
The utility model relates to a kind of breaker more particularly to a kind of breaker transmission modules.
Background technique
Function of the breaker in medium voltage switchgear equipment be mainly when normal or current overload carry out circuit carrying,
It cut-offs and closes, it can be seen that, breaker is a highly important part in medium voltage switchgear equipment.Transmission module is that vacuum is disconnected
One of the core of road device, the part are related to the mechanical property parameter of the transmission efficiency cooperated with mechanism and vacuum interrupter
And its adjustment.
The breaker transmission module of the prior art uses cam drive mode, according to the distance of cam rail to main-shaft core
Difference realizes the divide-shut brake function of breaker.
As shown in Figure 1 and Figure 2, it is connect in the prior art using monoblock type guide post with vacuum interrupter, connection type is using solid
Fixed connection, and regular screw threads is mostly used to connect.
The shortcomings that prior art:
1, guide post is monoblock type, and transmission module is not easy to assemble, and needs to assemble using special tooling；
2, guide post is monoblock type, if connection screw thread destruction just needs integral replacing, replacement is inconvenient and replacement cost is high, is increased
When processing；
3, monoblock type guide post connection screw thread is regular screw threads, and precision is low when mechanical property small parameter perturbations, time-consuming；
4, guide post is monoblock type, and craftsmanship is poor, and Fei Cai is at high cost.
Utility model content
The purpose of the utility model is to provide a kind of breaker transmission modules.
The purpose of this utility model is achieved through the following technical solutions:
The lower end of the breaker transmission module of the utility model, including guide post, the guide post is equipped with screw hole, the screw hole
In studs is housed, the guide post is connect by the studs with vacuum interrupter moving contact.
The breaker use provided by the embodiment of the utility model it can be seen from above-mentioned technical solution provided by the utility model
Transmission module is easily assembled, cost is lower, transmission is more reliable, replacement is more convenient.

Specific embodiment
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The breaker transmission module of the utility model, preferable specific embodiment is:
Including guide post, the lower end of the guide post is equipped with screw hole, studs is housed in the screw hole, the guide post passes through institute
Studs is stated to connect with vacuum interrupter moving contact.
One end that the studs is connect with guide post is equipped with fastening nut.
One end that the studs is connect with guide post uses left hand thread, and the fastening nut is left-handed nut.
One end that the studs is connect with vacuum interrupter moving contact uses fine thread.
The breaker transmission module of the utility model improves transmission module assembly process process, saves working hour, improves assembly
Efficiency；Improve adjustment accuracy when mechanical property fine tuning；Reduce replacement cost；Improve guide post processing technology, raising and vacuum
Arc-chutes connection reliability.
Specific embodiment:
As shown in Figure 3, Figure 4；
The monoblock type guide post for connecting vacuum interrupter moving contact is changed to studs and guide post type of attachment, improves guide post
Processing technology, material saving reduce replacement cost, while improving transmission module assembly process process, only need universal tooling
Assembling is completed, working hour is saved, improves assembly efficiency；
Studs and vacuum interrupter connecting pin use closely-pitched structure, connects with guide post using left hand thread, improve and
The reliability of vacuum interrupter connection, reliable transmission improve adjustment accuracy when mechanical property fine tuning；
Transmission module principle:
Attached drawing 3, Fig. 4 are closing positions shown in showing, main shaft drives 1 rotation of shaft set to shown position, that is, shaft set
Longest distance position away from main-shaft core, moves downward pin 10 in the vertical slots of guide post, and limit sleeve 7 is driven to move downward,
Here limit sleeve has the function of limit, guiding, transmission.Pressure spring 4 is under pressure, and passes to vacuum by studs 6 and goes out
Arc chamber moves back and forth in this way to realize divide-shut brake.
The utility model is connect with the connection of vacuum interrupter moving contact using studs；Transmission parts using guide post with
Studs type of attachment, is easily assembled and replacement cost is low；Studs and vacuum interrupter connecting pin use closely-pitched structure,
Reliable transmission, adjustment parameter are more accurate.
The utility model reliable transmission saves working hour, worker is facilitated to install；Replacement cost is low；When mechanical property is finely tuned more
Add precisely；Modularized design, positioning is reliable, stable drive.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
