An operation mechanism (9) is arranged on a lateral side of the base support (1). The miniature high voltage vacuum load switch can be put in a smaller high-voltage switch cabinet and is small in size.

Description

The miniaturization high-voltage vacuum load switch
Technical field
The utility model relates to a kind of miniaturization high-voltage vacuum load switch, and its small volume is joined the I of cabinet width and tapered to 550mm, than the miniaturization that is easier to realize high-tension switch cabinet.
Background technology
Existing air-insulated high-voltage vacuum load switch relative volume is larger, isolating switch and vacuum interrupter guarantee that by the linkage locking device " five is anti-" requires, (implication of " five anti-" namely: isolating switch can only be behind the vacuum interrupter separating brake, just can carry out breaking-closing operating, earthed switch only just can carry out breaking-closing operating behind the isolating switch separating brake), so the volume of class high-voltage vacuum load switch is bigger than normal, can not be placed in the small and exquisite switch cubicle of volume, can't satisfy the requirement of miniaturization.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of small volume is provided, and joins the little miniaturization high-voltage vacuum load switch of cabinet width.
The purpose of this utility model is achieved in that
The utility model miniaturization high-voltage vacuum load switch, comprise underframe, the front side of described underframe is provided with many group insulators from top to bottom, described insulator all is horizontally disposed with, the front end of two groups of insulators is respectively equipped with upper bracket and lower carriage wherein, be provided with vacuum interrupter between described upper bracket and the lower carriage, the front end of the insulator that links to each other with upper bracket also is hinged with isolation knife, described isolation knife is obliquely installed to the underframe direction at the closing position blade row, be the tilting structure, the side of described underframe also is provided with operating mechanism.
Also be fixed with the insulating supporting post between described upper bracket and the lower carriage.
The front end sleeve of described isolation knife has insulating shield.
Described isolation knife and vacuum interrupter are realized interlocking by the cam interlocking mechanism device.
The utility model miniaturization high-voltage vacuum load switch has the following advantages:
The isolation knife of the utility model miniaturization high-voltage vacuum load switch adopts the tilting structure, reduced the shared space of isolating switch, width was less when cabinet was joined in assurance, the cutterhead of isolation knife adopts the vertical slice structure of mould molding, contact-making surface increases, the contact better effects if, and the isolation cutter head adopts the insulating shield composite insulation structure, strengthen insulating protection, improved degree of protection.Isolating switch and vacuum interrupter are to realize interlocking by the cam interlocking mechanism device, and it is more reliable to interlock.
Description of drawings
Fig. 1 is the structural representation of the utility model miniaturization high-voltage vacuum load switch.
Fig. 2 is the left view when isolation knife and vacuum interrupter separating brake among Fig. 1.
Fig. 3 is the right view when isolation knife and vacuum interrupter close a floodgate among Fig. 1.
Among the figure: underframe 1, insulator 2, upper bracket 3, lower carriage 4, vacuum interrupter 5, insulating supporting post 6, isolation knife 7, insulating shield 8, operating mechanism 9, cam interlocking mechanism 10.
Embodiment
Such as Fig. 1 to Fig. 3, the utility model relates to a kind of miniaturization high-voltage vacuum load switch, it comprises underframe 1, the front side of described underframe 1 is provided with many group insulators 2 from top to bottom, described insulator 2 all is horizontally disposed with, and wherein the front end of following two groups of insulators 2 is respectively equipped with upper bracket 3 and lower carriage 4, is provided with vacuum interrupter 5 between described upper bracket 3 and the lower carriage 4, also be fixed with insulating supporting post 6 between upper bracket 3 and the lower carriage 4, for increasing the resistance to overturning of product.
The front end of the insulator 2 that links to each other with upper bracket 3 also is hinged with isolation knife 7, the front end sleeve of isolation knife 7 has insulating shield 8 to come the reinforced insulation protection, this isolation knife 7 is obliquely installed to the underframe direction at the closing position blade row, be the tilting structure, so just reduced isolation knife 7 shared volumes, the I of the width of switch cubicle is to 550mm when guaranteeing to join cabinet, described isolation knife 7 is isolating switch, its cutterhead adopts formed in mould vertical slice structure, and contact-making surface increases, and the contact effect is better.
Isolation knife 7 adopts cam interlocking mechanism 10 to link to each other with vacuum interrupter 5, guarantees " five is anti-" requirement by this interlocking device 10, and isolation knife 7 can only behind vacuum interrupter 5 separating brakes, just can be carried out breaking-closing operating.
The side of described underframe 1 also is provided with the action that operating mechanism 9 is controlled high-voltage vacuum load switch.
The course of work of this miniaturization high-voltage vacuum load switch is as follows:
The combined floodgate course of work: first rotation isolation axle, isolation knife 7 is closed a floodgate, then rotate the vacuum main shaft so that the operating mechanism spring energy-storage, rotate to certain position after, spring energy discharges rapidly and drives vacuum interrupter 5 rapid closings.
The separating brake course of work: the opening button of pressing first on the operating mechanism 9 drives brake separating mechanism, tripping spring is discharged drive vacuum interrupter 5 quick acting switching-offs, and then rotation isolation axle makes isolation knife 7 separating brakes.
