It applies example and attached drawing is cooperated to be explained in detail.
Fig. 1 and Fig. 2 are please referred to, the present embodiment provides a kind of board-like breaker mechanisms of the novel clamp for gas-filling cabinet, including
Frame body 10, vacuum interrupter 11, insulated pull rod unit 12 and main bus-bar 13；The frame body includes the first support plate 101, second
Fagging 102, third support plate 103 and clamping plate 104, the first support plate, the second support plate and third support plate are successively set on folder
Between two plates of plate, the insulated pull rod unit is arranged between the first support plate and the second support plate, vacuum interrupter setting
Between the second support plate and third support plate, one end of insulated pull rod unit is arranged in the first support plate, insulated pull rod list
The other end of member is arranged on one end of vacuum interrupter, and the main bus-bar is arranged on clamping plate, and main bus-bar goes out positioned at vacuum
Between arc chamber and third support plate.The cross section of the main bus-bar is rectangle.The frame body is insulation frame body.
Vacuum interrupter and insulated pull rod unit are fixed on frame body in the present embodiment, and make vacuum interrupter
The center line of center line and insulated pull rod unit connects vacuum interrupter and gas-filling cabinet on the same horizontal line, through main bus-bar
Interior other electrical equipments.When in use, it in order to guarantee the reliable splitting or integrating function of breaker, is pulled by insulated pull rod unit
Circuit safety in vacuum extinction room disconnects or merges, i.e., insulating properties excellent by vacuum in the vacuum tube of vacuum interrupter,
Make after mesohigh circuitry cuts power supply blow-out and to inhibit electric current rapidly, improves breaker in the safety of splitting or integrating lock circuit mechanism
Property, it ensure that breaking capacity of breaker is strong, circuit life is long, the performance of high reliablity, and the vacuum interrupter of breaker
Part has the characteristics that service life non-maintaining, small in size, therefore can effectively improving gas-filling cabinet.
Wherein main bus-bar is are as follows: is used as between connection cabinet in voltage switchgear and each electrical equipment is converged in cabinet
Collection, distribution and the conductor for transmitting electric energy.Fever and electrodynamic action caused by short circuit current are born when short trouble occurs,
It is as primary element important in the high and low pressure complete sets of electric switchgears and control devices.And the cross section of main bus-bar can be with are as follows: round or groove profile.By
When the cross-sectional area of main bus-bar is identical, the perimeter of the main bus-bar of rectangular shape is longer than the perimeter of round main bus-bar, therefore its
Good heat dissipation effect, cooling condition is good, and when the temperature increase of main bus-bar, the electric current that rectangle main bus-bar is passed through is more main than circle
Bus it is big, and the kelvin effect of rectangle main bus-bar is relatively uniform, therefore the cross section of preferred main bus-bar is square in the present embodiment
Shape.
Frame body described in the present embodiment further includes fixing seat 14, and the fixing seat is arranged in the first support plate.It is described exhausted
