Abstract
The invention relates to insulating cylinder in use for installing fuse in medium or high voltages. The insulating cylinder includes fuse wire cylinder, insulating end cover, and mutual matched ring outer saliency and ring outer groove on fitted surface of outer ring of fuse wire cylinder and insulating end cover. Features are: good insulatibity, and easy of installation and use.
Description
Technical field
The invention belongs to middle and high voltage switching station, relate to a kind of fuse mounting insulation tube that middle and high pressure fuse is installed that is used for.
Background technology
Fuse mounting insulation tube is to be used for fixing the parts that fuse is installed in the mesohigh switchgear, existing structure generally comprises the fuse unit of insulating material and is enclosed in the insulated end cover of fuse unit end, because insulated end cover and fuse unit exist fit clearance, the conducting bracket of fuse also is installed near the end simultaneously, therefore, the coupling part of insulated end cover and fuse unit is the weak link of insulation, has reduced the insulation property of product.
Summary of the invention
Technical problem to be solved by this invention is, a kind of good insulating, fuse mounting insulation tube easy to install are provided.
Fuse mounting insulation tube of the present invention includes fuse unit and is installed in the insulated end cover of fuse unit end, has groove outside the annular outer process that cooperatively interacts and the annular on the matching surface of fuse unit and insulated end cover outer ring.It is how right that described annular outer process and the outer groove of annular can be provided with according to the needs of the class of insulation.The center of described insulated end cover has opening striker chamber inwardly, there is a striker to be placed in the striker chamber, the less shank of the diameter at striker center passes from the through hole of striker chamber bottom centre, the striker root is the bigger striker pedestal of diameter, is respectively arranged with annular inner process and the annular inner groovy that cooperatively interacts on striker pedestal and the bottom surface, striker on the other side chamber.It is how right that described annular inner process and annular inner groovy also can be provided with.
The present invention is simple in structure, easy for installation, because between insulated end cover and fuse unit, and be provided with the structure that annular projection and annular groove cooperate between insulated end cover and the striker pedestal, increase the creepage distance of matching surface greatly, thereby improved the insulation property of bound fraction.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
As shown in the figure, in the structure of this fuse mounting insulation tube, the outer ring of insulated end cover 2 and fuse unit 1 end are connected, on the matching surface of insulated end cover, be provided with an annular outer process 3, on the matching surface of fuse unit end, be provided with groove 4 outside the annular that cooperates with annular outer process simultaneously.Be provided with striker chamber 5 at the center of insulated end cover, be provided with striker 6 in the striker chamber, shank 7 front ends of striker pass from the through hole 8 of bottom, striker chamber, then cooperatively interact by annular inner process 9 and annular inner groovy 10 between the root striker pedestal of striker and the bottom surface in striker chamber.
Claims (2)
1. fuse mounting insulation tube, include fuse unit (1) and be installed in the insulated end cover (2) of fuse unit end, it is characterized in that: on the matching surface of fuse unit and insulated end cover outer ring, have groove (4) outside the annular outer process (3) that cooperatively interacts and the annular; The center of described insulated end cover (2) has opening striker chamber (5) inwardly, there is a striker (6) to be placed in the striker chamber, the shank at striker center (7) passes from the through hole (8) of striker chamber bottom centre, is respectively arranged with cooperatively interact annular inner process (9) and annular inner groovy (10) on the striker pedestal of striker root and the bottom surface, striker on the other side chamber.
2. fuse mounting insulation tube according to claim 1 is characterized in that: it is how right that described annular inner process and annular inner groovy are provided with.
