The novel high-tension vacuum switch comprises a vacuum arc-extinguishing chamber, an electromagnetic drive mechanism, a driving mechanism and a manual switch-off mechanism. The novel high-tension vacuum switch is characterized in that the whole adopts the lifting building-block structure; the novel high-tension vacuum switch is provided with switch-on buffered elastic elements and elastic bodies, a cross beam driven by a driving arm and the pull-drag manual switch-off mechanism. The utility model has compact and reasonable structure, very convenient maintenance and disassembly, good electric performance, multiple breaking rated short-circuit current times, no switch-on bounce and high mechanical lifetime.
Description
The utility model relates to the high-pressure vacuum breaker technical field.
High-pressure vacuum breaker has developed into series of products, ZN3-10 type product structure is fairly simple, it adopts the pressing type structure, electromagnetic drive mechanism and transmission mechanism are contained in the substrate both sides respectively, the connection of high-pressure vacuum breaker and disjunction are to drive elementary connecting lever, secondary connecting lever, insulated tension pole successively by main shaft to finish, this product transmission mechanism is more, poor-performing.ZN5-10 type product also is to adopt the pressing type structure, and electromagnetic drive mechanism and transmission mechanism are an integral body, are horizontally installed in the base, and its performance is general.Existing high-pressure vacuum breaker owing to there is structural problem, makes that its performance index are undesirable, and is not high as disjunction rated short circuit current number of times, only is 30 times generally, and the closing rebound time is longer, and mechanical endurance is short.
The purpose of this utility model is that design is a kind of rational in infrastructure, convenient disassembly, and good performance indexes is closed a floodgate and is not had the novel high-pressure vacuum circuit-breaker of spring.
To achieve these goals, the utility model adopts following technical proposals.
A kind of high-pressure vacuum breaker, comprise vacuum interrupter, electromagnetic drive mechanism, transmission mechanism, manual brake separating mechanism, it is characterized in that: the whole lifting modular construction that adopts of high-pressure vacuum breaker, be that top is the vacuum interrupter that is lifted on the conductive plate, the middle part is substrate and transmission mechanism thereon, and the bottom is the electromagnetic drive mechanism that is positioned at the substrate lower central; The dagger place is provided with flexible member on the conductive plate on every phase vacuum interrupter, is provided with elastomer in the insulator upper hole; The crossbeam that the top that transmission mechanism comprises the left and right sides transmission arm that is assemblied on the main shaft and the right transmission arm that keeps left upwards promotes to close a floodgate links to each other with the insulator bottom; Manual brake separating mechanism by the branch brake lever rod assembling that has draw ring, assemble with the clasp that divides the brake lever rod joint arm that assembling is connected, the linking arm that is connected with the joint arm, be connected with linking arm, two ends are hung in that mechanism rack is assembled and the extension spring of branch brake lever rod fit on is formed; Last dagger profile has the multiple tracks groove.
Owing to adopted technique scheme, compared with the prior art, compact conformation is reasonable, repair demolition is very convenient, realizes the electricity function index leap, and the disjunction rated short circuit current is brought up to 60 times by 30 times, close a floodgate not have spring, brought up to 14000 time by 9000-10000 time of past mechanical endurance.
Description of drawings:
Fig. 1 is the high-pressure vacuum breaker front view.
Fig. 2 is the high-pressure vacuum breaker end view.
Fig. 3 manual brake separating mechanism figure.
Fig. 4 goes up dagger figure.
Fig. 5 is the insulation subgraph.
Below in conjunction with description of drawings, the utility model is further described.
The high-pressure vacuum breaker overall structure is the lifting cordwood system type, top is vacuum interrupter (1), every is separate unit mutually, straight empty arc control device are lifted on the conductive plate (9) with bolt (8), the middle part is substrate (16) and the transmission mechanism that comprises the crossbeam (4) that top that symmetry is assemblied in two transmission arms (7) on the main shaft (6) and upwards promotes to close a floodgate by transmission arm is connected with the insulator bottom thereon, and the bottom is mounted in the electromagnetic drive mechanism that is positioned at the substrate lower central.Because vacuum interrupter adopts lifting, can reduce the bounce that produces when closing a floodgate, modular construction reduces the dismounting time mainly for convenient disassembly, changes the vacuum extinction chamber unit that damages, and only needs to plant somewhat.
When closing a floodgate, produce bounce for solving high-pressure vacuum breaker, the utility model is except that adopting the vacuum interrupter lifting, also adopted on the conductive plate on every phase vacuum interrupter dagger (2) to locate to be provided with the flexible member (5) of appropriate parameter, in the insulator upper hole, be provided with one anti-one positive elastomer (11), insulator links to each other with the moving contact conducting rod by bearing pin (10), make vacuum interrupter be in quick condition like this, its natural frequency is an ideal value, be complementary with the elastomer in the insulator upper hole, can realize that the high-pressure vacuum breaker combined floodgate does not have the spring ideal effect.
By being contained in the outer branch brake lever rod assembling (12) that has draw ring of mechanism rack assembling (17), assemble the joint arm (13) that is connected with bearing pin (18) with dividing brake lever rod, the linking arm (14) that is connected with the joint arm with bearing pin (19), the clasp assembling (15) that the middle part that one end is connected with the mechanism rack assembling with bearing pin (20) is connected with linking arm with bearing pin, two ends are hung in the mechanism rack assembling and divide the manual brake separating mechanism of extension spring (3) composition of brake lever rod assembling, changed traditional inwards by the function of manual brake separating, and adopt the mode that pulls to finish the task of manual brake separating, overcome when general assembly and debugging, casualty accident and the on-the-spot inconvenience of using have taken place.
The utility model is in order to reduce the size of vacuum interrupter, and the creepage distance of dagger in the increase is left the multiple tracks groove on last dagger cylindrical.
