Abstract
The utility model relates to a component structure of a handcart type high-voltage switch cabinet, in particular to a high-current contact for a handcart cabinet, which is utilized as a static contact of a handcart type switch cabinet. The high-current contact consists of a conductor and an insulation shell, the conductor consists of a substrate and plugging boards, the substrate is disposed vertically, the plugging boards which are mutually parallel have two, the two plugging boards which are perpendicular to the substrate are disposed vertically, two parallel inserting grooves which are parallel are arranged on a rear-end wall plate of the insulation shell, the two plugging boards penetrate through the inserting grooves and extend into an inner cavity of the insulation shell, and the substrate is located outside the insulation shell and is fixedly connected with the insulation shell through a fastener. The high-current contact can be utilized as a static contact of a handcart cabinet, has relatively strong radiating capacity, and is simple in structure and convenient in manufacturing and mounting.
Description
Technical field
The utility model relates to the modular construction of handcart type high-voltage switch cabinet, specifically is a kind of large current contact for handcart type cabinet that is used as the fixed contact of handcart switch cabinet.
Background technology
In conventional hand trucks formula switch cubicle, the grafting part of fixed contact adopts the tabular of circular cylindrical shape or level usually, be used for be installed in handcart on as moving contact Mume flower contact or duckbilled contact peg graft and to cooperate, the fixed contact major part is positioned in the insulation casing.This structure is used for the shape cabinet of big current class, can have following problem:
1,, cause dynamic and static contact contraposition inaccurate and influence its reliable grafting because contact format is bigger, and moving contact in use can be sagging because of deadweight;
2, because current class is big, and contact temperature rise in service is higher, and fixed contact main body major part covers in the insulation casing, is unfavorable for heat radiation, has influenced the reliability of equipment operation.
Summary of the invention
Technical problem to be solved in the utility model is that providing a kind of can make it have stronger heat-sinking capability as the large current contact for handcart type cabinet of fixed contact, and simple in structure, manufacturing and easy for installation.
Large current contact for handcart type cabinet of the present utility model is made up of electric conductor and insulation casing, and described electric conductor is made up of the substrate that is used for connecting busbar in the cabinet and these two parts of plugboard that are used for cooperating with the moving contact grafting; Described substrate vertically is provided with, described plugboard has two that are parallel to each other, two plugboards and substrate is perpendicular and also vertically be provided with, have two parallel slots on the rear end wallboard of described insulation casing, two above-mentioned plugboards pass and stretch into from described slot in the insulation casing inner chamber, and described substrate is positioned at the insulation casing outside and is connected and fixed by securing member and insulation casing.
The rear end surface of described insulation casing is provided with some boss, the substrate inner surface is leaned against on the boss and and forms the space between the rear end surface of insulation casing.
Have the inside and outside heat radiation slotted eye that connects on the rear end wallboard of described insulation casing.
The utility model has the advantages that: 1, simple in structure, manufacturing and easy for installation; 2, whole contact electric conductor is only pegged graft and partly is positioned at insulation casing, and most of entity of electric conductor is positioned at outside the insulation casing, helps heat radiation; In addition, the heat that the part of pegging graft produces in running also can be discharged swimmingly by heat radiation slotted eye on the wallboard of insulation casing rear end and outside space, has also improved radiating effect; 3, because hard straight setting of two plugboards, can be with the hard straight duckbilled contacts mates that is provided with as moving contact, even sagging certain because of gravity produces of moving contact also can not produce bigger influence to the grafting process, improve the reliability of pegging graft.
