Abstract
The utility model relates to an electric conduction current carrying body which has the advantages of high mechanical strength, good current shunting, quick heat dispersion, high interchangeability, small volume and stable heat stability. The electric conduction current carrying body is composed of a conductive plate, a contactor seat and a contacting finger, wherein, the conductive plate is in a shape like the Chinese character ' shi ', and the tail end of the conductive plate is provided with a circular mounting basal seat which is integrated with the conductive plate into one body.
Description
Technical field
The utility model belongs to a kind of appliance switch element, particularly a kind of Knife type vacuum circuit breaker with three-station switch.
Background technology
The Knife type vacuum circuit breaker with three-station switch that the dynamic and static contact of existing high pressure is equipped with is to be made of contact base, the straight-plate-type conductive plate that is inserted into contact base one side, the fingertip that is installed in the contact base opposite side, and its end is the installation position, and fingertip is arranged on the contact base in the form of a ring.Because conductive plate is the flat copper bar, its bad mechanical strength, area of dissipation are less relatively, and thermal stability is bad.In addition,, and in practical operation, be difficult to guarantee angle in manufacture process, can cause copper bar off-centre, influence concentricity owing to copper bar needs its end is curved the right angle.When the fingertip in the Knife type vacuum circuit breaker with three-station switch is inserted fixed contact, can squeeze bad contact; If after clamp-oning contact by force, also can cause the contact distortion, make it lose interchangeability.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of mechanical strength height is provided, shunts, rapid heat dissipation, has interchangeability, little, the reliable Knife type vacuum circuit breaker with three-station switch of thermal stability of volume.
This Knife type vacuum circuit breaker with three-station switch is made of conductive plate, contact base and fingertip, and its special character is that said conductive plate is " ten " font, and the conductive plate end has one to be the circular mounting base of one with conductive plate.
According to above-mentioned Knife type vacuum circuit breaker with three-station switch, said fingertip is double-ring and is distributed on the contact base, dwindling wire spacing, to reduce cost,
According to above-mentioned Knife type vacuum circuit breaker with three-station switch, said contact base and conductive plate are one, with further raising mechanical strength.
The utility model has the advantages that the mechanical strength height, shunt, area of dissipation is big, rapid heat dissipation, little, the Heat stability is good of volume, and have interchangeability, and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Embodiment
As shown in the figure, this Knife type vacuum circuit breaker with three-station switch has " ten " font conductive plate 2 of being made by copper material, the end of said conductive plate 2 is to be the circular mounting base 1 of one with conductive plate 2, on the mounting seat 1 installing hole is arranged, the other end at conductive plate 2 is to be the contact base 3 of one with conductive plate 2, the opposite side of said contact base 3 has circular interior erecting bed 3A and the outer erecting bed 3B of ring-type respectively, interior, outer erecting bed 3A, be evenly distributed with inner card cage 5 and exterior bayonet slot 13 on the 3B, on contact base 3 outer walls, by screw end bowl 4 is installed near exterior bayonet slot 13 positions, interior, exterior bayonet slot 5, in being equipped with respectively on 13, outer fingertip 6,11, in said, outer fingertip 6,11 in the form of a ring and in being evenly distributed on, outer erecting bed 3A, on the 3B, interior, outer fingertip 6, shell fragment 8 is housed respectively on 11,10, interior, outer fingertip 6,11 inwall and shell fragment 8, in 10 outer surface is equipped with respectively, outer finger mount 7,12.
When reality was used, the fingertip 7,12 of this Knife type vacuum circuit breaker with three-station switch inserted in the stationary contact shape 9.
