Description
[technical field]
The utility model relates to the anti-flashover insulating case in high voltage field, particularly a kind of resistance.
[background technology]
The resistance of exposed to air is in when normal operation, and there is voltage in two interpolars, and this voltage prolongs the insulating capacity of face for resistance usually, is not enough to puncture and forms prolong the face flashover.Yet, when resistance when bearing in short-term heavy current impact, according to Ohm's law, its both end voltage also will sharply raise, and just might over the insulation level that prolongs face between resistance the two poles of the earth, cause resistance to prolong face flashover phenomenon this moment, form resistive short, cause fault, can be accidents caused when serious.
For this type of phenomenon, usually just smear the insulation glaze at the face that prolongs of resistance, prolong the anti-flashover performance of face with increase, or the overall dimension of increase resistance reduces the creepage distance that compares.For the former, the flashover phenomenon also exists sometimes, is mainly that the distance of resistance two interpolars does not change, and flashover is actual to be occurred in the air that resistance prolongs face.For the latter, though can solve problems, the increasing of the overall dimension of resistance tends to affect the overall structure of resistance place circuit, makes volume receive certain impact, so that the raising of cost has limited use.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of resistance with preventing the flashover insulating case, and this insulating case is sleeved on resistive surface, prevents that in order to increase the creepage distance of resistance two interpolars, to reach resistance from prolonging the purpose of face flashover.
The technical solution of the utility model is:
Resistance comprises that with anti-flashover insulating case one is sleeved on the insulating case of resistance outside, and its inner surface coordinates with the resistance outer surface, and this insulating case outer surface radially is provided with one or more fins that are parallel to each other, for increasing the creepage distance of described resistance interpolar.
As the further improvement of such scheme, this insulating case has a smooth inner surface, is used for smearing insulation coupling bonding agent.
The utility model has the advantage of: the utility model is simple in structure, and is with low cost, easy for installation, need not change electric resistance structure, can reach to promote the purpose that resistance prolongs the anti-flashover ability of face.
[description of drawings]
Fig. 1 is structural representation of the present utility model,
Fig. 2 is front view of the present utility model.
In figure: 1, insulating case; 2, fin; 3, insulating case inner surface.
[embodiment]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Referring to Fig. 1,2, resistance comprises with anti-flashover insulating case the insulating case 1 that is sleeved on the resistance outside, and its inner surface 3 coordinates with the resistance outer surface, quilt cover resistance can be column or sheet.Insulating case 1 outer surface radially is provided with a plurality of fins that are parallel to each other 2, for increasing the creepage distance of resistance interpolar.Insulating case 1 is made by insulating material, can be silicon rubber or epoxy resin.According to Fig. 1 middle distance, if insulating case 1 outer surface has three fins 2, and the height of fin 2 is a, and the face creepage distance that prolongs that resistance is original is 3a, and resistance two interpolar air clearances are from being also 3a.And by after the effect of insulating case 1, making the creepage distance of resistance two interpolars increase to 8a, the air clearance of resistance two interpolars is from being increased to 6a, makes on the insulation property of resistance to have promoted more than 1 times.
Insulating case 1 has a smooth inner surface 3, is used for smearing insulation coupling bonding agent, and purpose is that the interpolar outer surface with resistance forms the strong bond layer.Insulation coupling bonding agent adopts one-component silicon rubber and metal, and the molded inorganic agent of nylon .ABS.PC.PVC plastic hot belongs to the hot setting type, and after solidifying, final strength is higher, and glued membrane is pliable and tough, and is water-fast, and media-resistant is ageing-resistant.After gluing, has long the adhered time.Be applicable to the bonding hot vulcanization of peroxide type silica gel and metal (stainless steel, copper, aluminium etc.), nylon, ABS, PC, PVC plastics, have simple to operately, bonding force is strong, the characteristics such as effect stability.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that do not break away from principle of the present utility model and spirit can be carried out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
