Abstract
The utility model relates to a breaker room valve structure of an open/close high-voltage switch cabinet, which comprises: a lower valve and an upper valve; and also includes a straight bar; the lower end of the straight bar is connected with one end of a first crank arm; and the other end of the first crank arm is connected with one end of a first connecting rod; and the other end of the first connecting rod is connected with one point of a long arm of a triangular second crank arm with uneven length; the joint of one ends of the long arm and a short arm of the second crank arm is fixed with the straight bar in rotating way; and the other end of the long arm of the second crank arm is connected with the lower valve; and the other end of the short arm of the second crank arm is connected with one point of a third crank arm through a second connecting rod; one end of the third crank arm is fixed with the upper end of the straight bar, and the other end of the third crank arm is connected with the upper valve; and the other end of the short arm of the second crank arm is connected between two ends of the third crank arm at one point through the second connecting rod and the third crank arm; a tension spring is also connected between the long arm of the second crank arm and the third crank arm; and because a connecting rod type structure is adopted, the whole valve mechanism is firm, reliable and safe.
Description
Technical field
The utility model relates to the breaker chamber of a kind of high-tension switch cabinet (KYN61-405), relates in particular to the valve structure of breaker chamber of opening and closing high-voltage switch cabinet.
Background technology
The breaker chamber valve of KYN61-40.5 type high-tension switch cabinet of the prior art all draws with steel wire rope, in running, very easily cause wire cable rupture like this or come off, valve is not opened sometimes, cause circuit breaker to push away to advance or can not shake, sometimes valve can fall on the contact arm of circuit breaker automatically, causes the major accident of three-phase shortcircuit and blast.The safe operation and the life safety of the equipment of giving have been brought injury.Moreover, will influence large quantities of power consumers in case have a power failure because the electric pressure of this switch cubicle is 35KV, the economic loss that causes is immeasurable.
Summary of the invention
The utility model technical issues that need to address have provided a kind of valve structure of breaker chamber of opening and closing high-voltage switch cabinet, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: following valve and last valve; Also comprise: a straight-bar; An end that connects one first connecting lever in described straight-bar lower end; The other end of first connecting lever connects an end of a first connecting rod; The other end of first connecting rod connects the more long-armed of second connecting lever different in size, triangular in shape; One end junction of the long-armed and galianconism of described second connecting lever and straight-bar rotation are fixing; The long-armed other end of second connecting lever joins with following valve; The other end of the galianconism of second connecting lever links to each other by any with one the 3rd connecting lever of a second connecting rod; One end of described the 3rd connecting lever and the upper end of straight-bar are fixed, and the other end of the 3rd connecting lever links to each other with last valve; The other end of the galianconism of described second connecting lever links to each other any between the two ends of the 3rd connecting lever by a second connecting rod and one the 3rd connecting lever; Between the long-armed of described second connecting lever and the 3rd connecting lever, also connect an extension spring.
Compared with prior art, the beneficial effects of the utility model are: owing to be link rod structure, make that whole valve mechanism is firm, reliable, safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: following valve 7 and last valve 8; Also comprise: a straight-bar 6; An end that connects one first connecting lever 1 in described straight-bar 6 lower ends; The other end of first connecting lever 1 connects an end of a first connecting rod 2; The other end of first connecting rod 2 connects the more long-armed of second connecting lever 3 different in size, triangular in shape; One end junction of the long-armed and galianconism of described second connecting lever 3 and straight-bar 6 rotations are fixing; The long-armed other end of second connecting lever 3 joins with following valve 7; The other end of the galianconism of second connecting lever 3 links to each other by any with one the 3rd connecting lever 5 of a second connecting rod 4; One end of described the 3rd connecting lever 5 and the upper end of straight-bar 6 are fixed, and the other end of the 3rd connecting lever 5 links to each other with last valve 8; The other end of the galianconism of described second connecting lever 3 links to each other any between the two ends of the 3rd connecting lever 5 by a second connecting rod 4 and one the 3rd connecting lever 5; Between the long-armed of described second connecting lever 3 and the 3rd connecting lever 5, also connect an extension spring 9.
Operation principle of the present utility model is when circuit breaker advances, pressing plate by the circuit breaker both sides is depressed first connecting lever 1, drive 3 rotations of second connecting lever by first connecting rod 2 simultaneously, the long-armed valve that will descend by second connecting lever 3 is opened, and meanwhile the galianconism of second connecting lever 3 promotes the 3rd connecting lever 5 by second connecting rod 4 and will go up valve and open.
When circuit breaker withdrawed from, the pulling force of deadweight and extension spring by valve was closed valve automatically.
The utility model is implemented the back and sound assurance is provided for the safe operation of equipment, has effectively avoided great and generation serious accident, has further improved the quality of product.
