The outer side of the contact end of the fixed contact is fixedly connected with a finger contact seat, a barrel-shaped body of a contact opening is arranged at one end of the finger contact seat, a central positioning rod hole is arranged in the middle of the finger contact seat, a screw rod is arranged at one end of the central positioning rod and passes through the central positioning rod hole to be fixed in a screw hole of the contact end of the fixed contact by screws, the other end of the central positioning rod arranged outside a contact opening is a circular-arc head body, and an inserting hole channel for the insertion of the circular-arc head body of the central positioning rod is arranged at the end of the central positioning rod corresponding to the middle of the movable contact. The electric connection device prevents electric arc from damaging electrical appliances by burning, enlarges the contact areas of the contacts, adopts a separated structure, and also has the advantages of simple structure, compact and small volume, few processing procedures, quick processing, safety, reliability, good electric conduction, low cost and long service life.
Description
Technical field
The utility model belongs to the arrangements of electric connection that a kind of Cubicle Gas-Insulated Switchgear is used.
Background technology
The fracture return voltage was very little when each contact of Cubicle Gas-Insulated Switchgear was cut circulation; When electric current is big; Arcing time is longer; For guaranteeing the good contact of two contacts, in fixed contact, establish the watchband fingertip of several ring-types usually, but the electric arc that two contacts of high power switch produce when separating often burns the watchband fingertip.On the other hand, each contact contact area is little, causes each contact poor electric conductivity.Have contact to be structure as a whole again, manufacturing procedure is many, and process velocity is slow, and quality is difficult to guarantee.
Summary of the invention
The purpose of the utility model is the arrangements of electric connection that a kind of Cubicle Gas-Insulated Switchgear of design is used, but arc protection burns infringement electrical equipment, enlarges each contact contact area; Adopt to divide a body structure, also have simple in structurely, compact volume is little; Manufacturing procedure is few, and process velocity is fast, and is safe and reliable; It is electrically good to conduct electricity, and cost hangs down the advantage with long service life.
For this reason; The utility model mainly is made up of fixed contact and moving contact; The fixed contact contact jaw outside is connected with the fingertip seat, and the fingertip seat is the barrel shape body that an end is established contact openings, and the central locating rod hole is established at fingertip seat middle part; Central locating rod one end is a screw rod; The screw rod end of central locating rod passes central locating rod hole spiral shell admittedly in the screw of fixed contact contact jaw, and the other end of central locating rod is convexly equipped with and outside contact openings, is circular arc head body, and moving contact middle part and central locating rod corresponding end are provided with the jack road of the circular arc head body end insertion that supplies central locating rod.Described jack road head inner end wall is provided with copper-tungsten portion.The circular arc head body end of described central locating rod is provided with copper-tungsten portion.Described fixed contact contact jaw lateral surface is provided with screw.Corresponding screw is provided with screw hole on the described fingertip seat medial surface.The said structure design has realized the purpose of the utility model.
But the utility model arc protection burns infringement electrical equipment, enlarges each contact contact area, adopt to divide a body structure, also has simple in structurely, and compact volume is little, and manufacturing procedure is few, and process velocity is fast, and is safe and reliable, and it is electrically good conduct electricity, the advantage of the low and long service life of cost.
Description of drawings
Figure is the structural representation of the utility model.
Embodiment
Arrangements of electric connection as shown in the figure, that a kind of Cubicle Gas-Insulated Switchgear is used mainly is made up of fixed contact 6 and 1 of moving contact, and the fixed contact contact jaw outside is connected with fingertip seat 4, and the fingertip seated connection touches the watchband fingertip 2 of establishing several ring-types on the inwall of opening.Described fixed contact contact jaw lateral surface is provided with screw 5.Corresponding screw is provided with screw hole on the described fingertip seat medial surface.Hold-down screw 7 passes the screw hole spiral shell and in the screw of fixed contact contact jaw lateral surface, the fingertip seat is fixed on the fixed contact contact jaw lateral surface admittedly.The fingertip seat is the barrel shape body that an end is established contact openings; The central locating rod hole is established at fingertip seat middle part; Central locating rod 3 one ends are screw rod, and it is solid in the screw of fixed contact contact jaw that the screw rod end of central locating rod passes central locating rod hole spiral shell, thereby make fingertip seat middle part establish central locating rod.The other end of central locating rod is convexly equipped with and outside contact openings, is circular arc head body.Moving contact middle part and central locating rod corresponding end are provided with the jack road 9 of the circular arc head body end insertion that supplies central locating rod.
Described jack road head inner end wall is provided with copper-tungsten portion 8.The circular arc head body end of described central locating rod is provided with copper-tungsten portion.Copper-tungsten portion electric conductivity is fabulous.
As shown in the figure, figure is moving contact and fixed contact the utility model normal operating conditions when joining, and is the switch closing position.Moving contact and fixed contact are connected.The central locating rod inserting is in the jack road; Electric current flows to moving contact through inwall and the central locating rod that fixed contact and fingertip seated connection touch opening; Through the multiple spot contact area; Realize extremely low contact resistance, this moment moving contact through gear drive, can move to the centre position and touch openend with the fingertip seated connection and separate.During separation; Moving contact separates earlier with the watchband fingertip that the fingertip seated connection touches in the openend; Central locating rod separates with moving contact at last; The electric arc that produces like this will can be avoided the electric lonely ablation watchband fingertip and the moving contact that produce in the burning of the copper-tungsten position of central locating rod circular arc head body end and moving contact.Central locating rod also plays guiding and enlarges contact area.
In a word, but the utility model arc protection burns infringement electrical equipment, enlarges each contact contact area, adopts and divides body structure; Also have simple in structurely, compact volume is little, and manufacturing procedure is few, and process velocity is fast; Safe and reliable, it is electrically good to conduct electricity, and cost hangs down the advantage with long service life.
