Abstract
The utility model discloses a contact knife of an indoor high voltage isolating switch; the surface of the conductive plate (1) of the contact knife is fixed with a plurality of groups of radiating plates (3) consisting of ribbed radiating fins, thus increasing the electric radiating area of the contact knife, improving the radiating property of the contact knife and being capable of properly reducing the material of the contact knife simultaneously when ensuring the temperature rising not to exceed an allowable value.
Description
Technical field
The utility model is particularly related to a kind of indoor high-voltage isolating switch, and is special relevant with the contact knife structure of indoor high-voltage isolating switch.
Background technology
Indoor high-voltage isolating switch is to isolate, connect, changing the device of getting in touch between electrified body and the electrical equipment under the non-loaded state of circuit in the electrical power distribution system.When isolating switch passed through rated current, the temperature rise of its energized components such as contact knife, contact etc. should not surpass the setting of country.The contact knife of existing indoor high-voltage isolating switch reduces temperature rise in order to increase area of dissipation, with the cross section increase of contact knife, be converted into the U type, but this measure can not effectively reduce temperature rise, and consumptive material is many.
Summary of the invention
It is few that the purpose of this utility model will be designed a kind of material consumption exactly, the indoor high-voltage isolating switch contact knife of perfect heat-dissipating.
Technical solutions of the utility model are: indoors the conductive plate surface of switch touching knife is fixed some groups of heating panels, and heating panel is made up of the heat radiation thin slice of band muscle shape.
This indoor high-voltage isolating switch contact knife greatly increased contact knife area of dissipation, reduced temperature rise.When guaranteeing that temperature rise is no more than permissible value, reduction contact knife material that can be suitable.Easily the medium material such as the pitch-dark heat dispersion of heat radiation can further improve if in these heat radiation sheet surface sprayings.
Description of drawings
Fig. 1 is the structural representation of existing indoor high-voltage isolating switch contact knife;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of an embodiment of the utility model indoor high-voltage isolating switch contact knife;
Fig. 4 is the vertical view of Fig. 3.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, conductive plate 2, heating panel 3, bolt 4, heat radiation thin slice
In Fig. 3, embodiment shown in Figure 4, conductive plate 1 surface be fixed with two heating panels 2 by bolt 3.Played muscle shape heat radiation thin slice 4 on the heating panel 2, the very big contact knife electric area that dispels the heat that increased.On the muscle shape of heating panel 2 heat radiation thin slice 4, be sprayed with pitch-darkly, the contact knife thermal diffusivity is further improved.
Claims (3)
1, a kind of indoor high-voltage isolating switch contact knife is characterized in that: the fixing some groups of heating panels (2) in the conductive plate of contact knife (1) surface.
2, a kind of indoor high-voltage isolating switch contact knife according to claim 1 is characterized in that: described heating panel (2) is made up of the heat radiation thin slice (4) of band muscle shape.
3, a kind of indoor high-voltage isolating switch contact knife according to claim 2 is characterized in that: be sprayed with easy heat radiation coating on the described heat radiation thin slice (4).
