Abstract
The utility model relates to a three-way contactor box, which comprises a main body, a skirt edge and a supporting edge are arranged on the outer ring surface of the main body, an inserting edge and a protection edge are arranged inside the main body, a protective cover and an outlet are also arranged on the outer ring surface of the main body, five or more than five skirt edges are arranged on the protective cover, to satisfy the use requirement of a switch cabinet with three contactors, and the three-way contactor box has good insulation and electrical performance.
Description
Technical field
The utility model belongs to a kind of insulating part, especially relates to being used for the insulating part of insulating contact in a kind of high-tension switch cabinet.
Background technology
The airtight switch cubicle of armored open type AC metal; be applicable to three-phase alternating current 50Hz; 40.5kV single busbar connection and single busbar connection disjunction electric power system; be mainly used in the power plant; power transformation is industrial and mining enterprises in one's power; the usefulness of electric energy is accepted and is distributed in conduct in the change distribution of skyscraper; and to circuit implementation control; protection and monitoring; and possesses perfect " five is anti-" function; contact box is used for moving in the isolating switch cabinet; fixed contact; anti-stop; a series of electricity reactions such as external equipment such as fixed contact and cabinet discharge; because traditional airtight switch cubicle of armored open type AC metal does not have supporting no metering cabinet; when increasing metering cabinet; needing increases by one group of contact, and common contact box has only two outlets, can't satisfy its requirement.
Summary of the invention
Can't satisfy the defective of the airtight switch cubicle instructions for use of armored open type AC metal with three groups of contacts at contact box of the prior art, the utility model aims to provide a kind of novel structure that has, and the threeway contact box of three outlets is arranged.
Another purpose of the present utility model is to improve insulation, the electric property of contact box.
For achieving the above object, the utility model has adopted following technical scheme: its structure comprises: body, and the body outer ring surface is provided with the shirt rim, support the limit, anti-safe edge, inserts is cast on the body, and its main points are: the outer ring surface of body also is provided with protective cover, outlet.
Further technical scheme: protective cover is provided with the shirt rim more than 5 or 5.
Beneficial effect: compared with prior art, the utility model is provided with protective cover by the outer ring surface at body, make it satisfy instructions for use,, make the threeway contact box have good electrical properties by be provided with the shirt rim more than 4 or 4 at protective cover with three switch contacts cabinets.
Description of drawings
Accompanying drawing is the sectional structure schematic diagram of an embodiment of the utility model.
Embodiment
Referring to accompanying drawing, the body 4 of threeway contact box, and be arranged on shirt rim 3 on the body 4, support limit 2, anti-safe edge 7 and protective cover 5 are overall structures, and its body is provided with outlet 6, by epoxy resin, curing agent, silicon powder mixes according to a certain percentage, adopts the molding for epoxy resin technology to make with inserts 1, make it satisfy instructions for use with three contacts, protective cover can be established the shirt rim more than 5 or 5, increases its creepage distance, makes it have very high insulation, electric property.
