Description
The utility model relates to a kind of low-voltage electrical apparatus, relates in particular to a kind of insulation of withdrawable circuit breaker.
When withdrawable circuit breaker was in separation or test position at breaker body, generally speaking, the live part of drawout chassis main circuit must be completely cut off reliably, to guarantee operating personnel or maintainer's personal safety.For realizing above-mentioned functions, between the link of drawout chassis main circuit socket and breaker body main circuit bus, the burst disk of an activity should be set.When breaker body was in separation or test position, drawout chassis main circuit socket should be fully isolated by burst disk; When breaker body was advanced near drawout chassis main circuit bus, this activity safety dividing plate should accurately promptly be opened.To the main technical requirements of burst disk transmission mechanism move exactly accurately, reliable, the additional drag when alleviating breaker body as far as possible and advancing.
The kind of drive of the drawer type universal circuit breaker burst disk that uses at present both at home and abroad roughly has three kinds: a kind ofly be the catch bar that is provided with the function inclined-plane on the breaker body, planar end or roller with catch bar inclined-plane promotion lifting burst disk supporter make the burst disk motion.In this mode, because by working on the catch bar inclined-plane, burst disk is produced inevitably the thrust of horizontal direction, and this thrust plays destruction to drawout chassis structure and burst disk, the corresponding structure part must keep enough intensity, to resist the influence of this thrust destruction, cause related components heaviness, operating physical force big, in addition, because the gradient on catch bar inclined-plane has certain limitation, the level of significance advance distance of breaker body must certainly will increase the degree of depth of drawout chassis more than or equal to the range of lift of burst disk.The second way is a turnover plate type, when circuit breaker was advancing, whole burst disk is upset upwards, and the disadvantage of this mode is because burst disk is the monoblock action, just the level of significance advance distance of circuit breaker must also certainly will increase the degree of depth of drawout chassis greater than the width of burst disk.More than two kinds of modes be very uneconomic for circuit breaker.The third mode is the double inclined plane that pushing ram has the isoceles triangle form, the burst disk operating parts is set to the scissor lever, the scissor lever piece is the special surface structure in this mode, the part processing cost is higher, and the relation of burst disk displacement scale and scissor lever piece longitudinal size and first kind of mode are similar, remove by comparison and reduced operating physical force, do not tackle the problem at its root.And owing to burst disk must slide on the special surface of scissor lever piece, as it is dumb to slide, and opens on one side burst disk appears in regular meeting, and the situation that another side is not opened is very unreliable.
Goal of the invention of the present utility model provide a kind of simple in structure, easy to process, cost is low and can reliably realize the burst disk mobile device of withdrawable circuit breaker insulation, its structure can realize the adjusting of breaker body horizontal displacement and burst disk vertical displacement size easily, thereby makes this device be applicable to any one withdrawable circuit breaker.
To achieve these goals, the utility model provides a kind of burst disk mobile device of withdrawable circuit breaker, by burst disk that is fixed together and dividing plate supporter, be fixed on the locating part on the drawout chassis side plate, the horizontal thrust unit that is fixed on the breaker body is formed, burst disk and dividing plate supporter are can be on vertical on the locating part under the driving of horizontal thrust unit, move down, its characteristics are that described locating part is a limit guide rail, described dividing plate supporter is fixed on back-moving spring on the described side plate and dividing plate connecting rod and links and be installed on the described limit guide rail with one respectively, and the other end of described dividing plate connecting rod connects with a drive link; Described drive link is installed on the fulcrum shaft and can fulcrum shaft is that rotate at the center under the promotion of horizontal thrust unit, and described fulcrum shaft is fixed on the drawout chassis side plate.
Drive link when above-mentioned burst disk mobile device, its characteristics are that circuit breaker is in link position and the angle between the dividing plate connecting rod are greater than 90 ° and be less than or equal to 180 °.
Above-mentioned burst disk mobile device, its characteristics are the connecting of described dividing plate supporter and dividing plate connecting rod, described dividing plate connecting rod and are movable the connection connecting of drive link.
Above-mentioned burst disk mobile device, its characteristics are that the front end of described drive link 1 is circular arc angle.
Above-mentioned burst disk mobile device, its characteristics are that described horizontal thrust unit is a column type driving shaft.
Adopt such scheme, when breaker body was in separation point position or test position, burst disk was pulled to make position by back-moving spring.When breaker body advances again, the cylindrical drive axial compression that is provided with on body two side plates compels to drive the drive link of two sides, make it to go to counterclockwise horizontal level, pulling dividing plate connecting rod, make it to drive burst disk and move downward the position that the main circuit bus exposes fully to the drawout chassis, otherwise, then reset by back-moving spring.
When breaker body in whole progradation, the supporter of burst disk slides in the limit guide rail on the drawout chassis side plate all the time, guarantees that burst disk moves both vertically up and down.
Because the front end of drive link is one circular-arc, the driving shaft on the breaker body side plate has reduced operating physical force when compressing drives it.
Angle between dividing plate connecting rod and the drive link greater than 90 ° and be less than or equal between 180 °, is regulated this angle all the time, promptly regulates two length of connecting rods, with regard to the size of the vertical displacement of the horizontal displacement of scalable breaker body and burst disk.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of burst disk make position of the present utility model
Fig. 2 is the end view of Fig. 1
Fig. 3 is the structural representation of burst disk open position of the present utility model
Fig. 4 is the end view of Fig. 3
