Description
Technical field
The invention belongs to transformer circuit protection equipment technical field, and in particular to a kind of circuit based on bar linkage structure is protected
Protection unit.
Background technology
Feeding switch is as the switch set in transformer outgoing line cabinet, the use of the feed for controlling outlet.Make
For feeding switch, the functions such as protection switch electrical equipment overload, disconnected phase, electric leakage are not only acted as, it is necessary to ensure going out when feeding switch
When mouthful end occurs short-circuit, can disjunction short circuit current, to protect transformer and to prevent the high-voltage switch gear of transformer upper end from producing dynamic
Make and caused by large area blackout.In use, can be with the breaker in disconnecting circuit, still when feeding switch closes a floodgate
When general feeding switch carries load in operation, the damage of feeding switch is easily caused.
The content of the invention
It is an object of the invention to provide a kind of circuit protection device based on bar linkage structure, solves feeding switch in circuit
Load is carried during combined floodgate, the problem of easily damage.
A kind of circuit protection device based on bar linkage structure of the present invention breaks the technical scheme adopted is that including breaker
Road device is sequentially connected in series feeding switch and travel switch by wire, is connected between feeding switch and travel switch by insulating tape
Linkage.
The features of the present invention also resides in,
Linkage includes base, is connected with base and is movably connected with its orthogonal frame, frame both sides
There are side link a and side link b, connected between side link a and side link b by connecting rod.
Side link a feeds disconnecting link by the band connection that insulate；Side link b passes through the band connection stroke disconnecting link that insulate.
The angle of side link a and bottom plate is 60 °~120 °, and the angle of side link b and bottom plate is 120 °~180 °.
Side link b, side link a are connected by bearing pin respectively with frame, and side link b, side link a and connecting rod pass through pin respectively
Axis connection.
The beneficial effects of the invention are as follows：A kind of circuit protection device based on bar linkage structure of the present invention is opened by using stroke
Drivening rod device triggering feeding switch is closed, ensure that feeding switch closes a floodgate in the case of no load, avoid feed and open
Situation about being closed a floodgate under with load is closed, protects feeding switch, it is simple to operate, there is good use value.

In figure, 1. feeding switch, 2. travel switches, 3. feed disconnecting links, 4. stroke disconnecting links, 5. breakers, 6. wires, 7. is exhausted
Marginal zone, 8. linkages, 9. side link a, 10. side link b, 11. connecting rods, 12. frames, 13. bearing pins, 14. bases.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of circuit protection device based on bar linkage structure of the present invention, as shown in figure 1, logical including breaker 5, breaker 5
Cross wire 6 and be sequentially connected in series feeding switch 1 and travel switch 2, be connected between feeding switch 1 and travel switch 2 by insulating tape 7
Linkage 8.
As shown in Fig. 2 linkage 8 includes base 14, it is connected with base 14 and its orthogonal frame 12, frame
12 both sides have been movably connected with side link a9 and side link b10, are connected between side link a9 and side link b10 by connecting rod 11
Connect.
Side link a9 connects feed disconnecting link 3 by insulating tape 7, and side link b10 connects stroke disconnecting link 4 by insulating tape 7；Even
Hack lever a9, side link b10 connect feeding switch 1, travel switch 2 respectively, trigger feeding switch 1 by linkage 8, stroke is opened
Close 2.
The angle of side link a9 and bottom plate 14 is 60 °~120 °, the angle of side link b10 and bottom plate 14 is 120 °~
180 °, side link a9 and side link b10 angle differ, and cause haul distance different, guarantee successively triggering feeding switch
1st, travel switch 2.
Side link b10, side link a9 are connected by bearing pin 13 respectively with frame 12, side link b10, side link a9 and connecting rod
11 are connected by bearing pin 13 respectively.
The present invention in use, when occurring overload, disconnected phase, the phenomenon of electric leakage in circuit, for protection circuit, electricity
In the case where itself carries load condition, its stroke disconnecting link 4 starts to close travel switch 2 in road, cuts off negative on feeding switch 1
Lotus, prevent feeding switch 1 from being worked in the case of with load；In the closing course of stroke disconnecting link 4 simultaneously, stroke disconnecting link 4 passes through
Side link a9 in the drivening rod device 8 of insulating tape 7, side link a9 start to move in a circle, and side link b10 is driven by connecting rod 11
Motion, side link b10 drive feed disconnecting link 3 by insulating tape 7；When stroke disconnecting link 3 is closed, touched by linkage 8
Hair feed disconnecting link 3 closes a floodgate, and breaker 5 disconnects, and protects the normal use of feeding switch 1.
The present invention triggers feeding switch 1 by using the drivening rod device 8 of travel switch 2, ensure that feeding switch 1 is not having
Closed a floodgate in the case of having load, avoid the situation that feeding switch 1 closes a floodgate under with load, protect feeding switch 1, operated
Simply, there is good use value.
