Abstract
Provided are insulation supports of a disconnecting switch. The insulation supports are fixed on an installation base, and petticoats with different diameters and composed of petticoat leaves are arranged on the peripheries of the insulation supports. The diameter of the petticoats increases gradually from one ends of the insulation supports to the other ends of the insulation supports. Simultaneously, the two insulation supports are perpendicularly fixed on the installation base. By adopting the technical scheme, the insulation supports of the disconnecting switch have the advantages that the petticoats with different diameters are arranged on the insulation supports and the diameter of the petticoats increases gradually from one ends of the insulation supports to the other ends of the insulation supports, environment adapting capability and voltage resistance classes of products can be effectively improved, and self-cleaning capability and uvioresistant capability of the products are improved.
Description
Technical field
The utility model relates to a kind of high voltage isolator, particularly a kind of insulation column of keeping apart.
Background technology
High voltage isolator is mainly used in important device for switching in power plant and the transformer station's electrical system, and it guarantees High-Voltage Electrical Appliances and the safety of device when service work, plays isolation voltage, fields such as the extensive suitable power of product, railway, mine, oil field.
Existing high voltage isolator comprises; First insulation column and second insulation column of vertical fixing on mounting panel is fixed with moving contact on first insulation column, is fixed with fixed contact on second insulation column; Also have two disconnecting links between two insulation columns; Two disconnecting links, one end is fixed with conductive pin and cooperates overlap joint conduction with moving contact, and the other end is articulated on the fixed contact, on said first insulation column and second insulation column identical cluster parachute of diameter is arranged.
Existing isolation switch insulation column, owing on first insulation and second insulation column identical cluster parachute of diameter is arranged, the adaptive capacity to environment of product and proof voltage grade are not very high, and self-cleaning ability and anti-uv-ray are not strong.
The utility model content
To the deficiency of existing apparatus, a kind of isolation switch insulation column of the utility model can effectively improve the adaptive capacity to environment and the proof voltage grade of product, improves the self-cleaning ability and the anti-uv-ray of product.
In order to reach this purpose, the utility model is realized through following technical scheme:
A kind of isolation switch insulation column, wherein, insulation column is fixed on the mount pad, and the insulation column periphery is provided with the cluster parachute of the umbrella leaf composition of different-diameter.
Further, said cluster parachute diameter is along the gradual increase of insulation column end to end.
Further, said insulation column has two, and vertical fixing is on mount pad.
The utility model adopts technique scheme; The beneficial effect that it has: on insulation column, adopt different cluster parachute of diameter and diameter along the gradual increase of insulation column end to end; Can effectively improve the adaptive capacity to environment and the proof voltage grade of product, improve the self-cleaning ability and the anti-uv-ray of product.
Description of drawings
Fig. 1 is the stereogram of a kind of isolation switch insulation column of the utility model.
Fig. 2 is the profile of a kind of isolation switch insulation column of the utility model.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
As depicted in figs. 1 and 2; A kind of isolation switch insulation column; Wherein, first insulation column 1 and second insulation column, 2 vertical fixing are on mount pad 3, and first insulation column 1 and second insulation column, 2 peripheries are provided with first cluster parachute 11 and second cluster parachute 21 of the umbrella leaf composition of different-diameter.Said cluster parachute diameter is along the gradual increase of insulation column end to end, and when specifically installing, the maximum umbrella leaf of diameter is positioned at top.Said isolating switch also comprises: moving contact 4, fixed contact 5, first disconnecting link 6, second disconnecting link 6 ' wherein be fixed with moving contact 4 on first insulation column 1 are fixed with fixed contact 5 on another insulation column.On said moving contact 4 one ends arc groove is arranged; Conductive pin 61 between this groove and two disconnecting links is connected; First disconnecting link 6 and second disconnecting link 6 ' be positioned at the both sides of dynamic and static contact side by side, wherein, first disconnecting link 6 and second disconnecting link, 6 ' other end are articulated on the fixed contact 5.Also be fixed with draw ring 62 in two disconnecting links, and with the snap close 63 of draw ring 62 overlap joint, snap close 63 other ends are buckled in to connect and collude on 64.
The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model can also have various changes and modifications, and these variations and improvement all are the protection range of the utility model.
