Abstract
The invention discloses an indoor high-voltage isolating switch static contact comprising a plurality of pairs of contact fingers and magnetic lock plates, wherein the contact fingers share a contact seat and are abreast arranged at both sides of screw rods; and the magnetic lock plates are positioned at the outer sides of the contact fingers. The indoor high-voltage isolating switch static contact is characterized in that the plurality of pairs of abreast arranged contact fingers are integral type flat bottom U-shaped pieces; when specific construction is carried out, clamp plates are arranged on the outer wall of the flat bottom U-shaped pieces in closed mode; and the clamp plates and the flat bottom U-shaped pieces are fastened on the contact seat together by fastening pieces. In the indoor high-voltage isolating switch static contact, innovative improvements are made aiming at the problems that crimp connection is adopted by the contact fingers and the contact seat of the existing static contact, processing and assembly requirements are high, the size and the precision of chamfering of orifice edge is difficult to control and the resistance of contact surface is easy to be large. With the adoption of the contact fingers with the structure of the integral type flat bottom U-shaped pieces and the technical scheme that the contact seat and the contact fingers are directly connected by the fastening pieces, the problem caused by contact of the spherical surface and an orifice edge line in the prior art is solved, and the purposes of reliable contact, low contact resistance, difficult heating and the like are achieved so that a product is suitable for operation in a site the rated current of which is larger than 4000A.
Description
[technical field]
The present invention relates to a kind of indoor high-voltage isolating switch fixed contact.
[background technology]
In the high voltage isolator Chang Zuowei power transmission and distribution loop voltage is arranged and divide, close the usefulness of circuit and isolation under the non-loaded situation, and this function mainly is based on effective connection the between moving contact and the fixed contact.Said fixed contact is made up of fingertip and touch base two parts, and the fingertip that is stamped to form by copper coin divides independently two row, and flexible fastening is installed in the static contact seat side by side in pairs.During use, moving contact supports out the fingertip of both sides by operational shock, and both fully contact the realization conducting function.
Fig. 1, Fig. 2 show the structure of existing fixed contact.The fingertip 3 of both sides, magnetic padlock plate 2 and one-sided spring base 5, spring 6 are fixedly mounted on the touch base 4 through screw rod 7, and four pairs of fingertips are shared a touch base 4.Be provided with a spherical 31 at fingertip 3 towards the bottom of facing the wall and meditating of touch base 4, the circumference of hole 41 peristomas on this spherical and the touch base forms line and contact, utilizes the active force realization fingertip 3 of spring 6 and the electrical connection between the touch base 4.During operation, the gap of two row fingertips about moving contact 8 inserts by operation power from top to bottom struts the fingertip 3 of both sides, and both fully contact the realization conducting function.But; There is following problem in the fixed contact of this structure when practical application: the one, owing to the overall structure reason of fixed contact; Be difficult to adapted in the above heavy current disconnecting switches equipment of 4000A, the 2nd, in the fixed contact processing of fingertip and touch base ball type of contact surface and assembling require very high, the particularly bad control of aperture edge chamfering size accuracy on the touch base; If a point tolerance is arranged; The resistance that will cause assembling contact-making surface is bigger than normal, and causes switch the heating phenomenon to occur in running status, sometimes even burn out fingertip and touch base.
[summary of the invention]
For solving the problems referred to above that prior art exists; The present invention aims to provide a kind of indoor high-voltage isolating switch fixed contact; After existing indoor high-voltage isolating switch is equipped the fixed contact of this structure; Not only can make product be suitable for big current work occasion, but also have processing, assembling requires low advantage.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: this indoor high-voltage isolating switch fixed contact; Comprise many to sharing a touch base, being arranged side by side fingertip in the screw rod both sides; And the magnetic padlock plate that is positioned at the fingertip outside, it is characterized in that: said many be the flat U of integral type type spare to the fingertip that is arranged side by side.
During practical implementation, on the outer wall of said flat U type spare, be provided with the clamping plate that the outer wall shape with this flat U type spare is complementary with being close to formula.
During practical implementation, a joint face of said flat U type spare, clamping plate and touch base is linked into an integrated entity by securing member locking.
During practical implementation, have a connecting piece, an end of this brace is locked by securing member with a joint face of said flat U type spare, clamping plate and touch base and is linked into an integrated entity, and the other end of this brace is the stiff end of touch base.
During practical implementation, the top of said flat U type spare has five pairs of fingertips that are arranged side by side.
Beneficial effect: compared with prior art; The fingertip and the touch base that the present invention is directed in the existing fixed contact adopt the compression joint type syndeton, and processing and assembling require high, and aperture edge chamfering size accuracy is difficult to control; Occur contact-making surface resistance problem bigger than normal easily, made the novelty improvement.The present invention is fit to the needs of rated current greater than 4000A from product, considers to strengthen the sectional area of contact knife, fingertip and touch base except that routine, emphatically the structure of fixed contact is improved.
The one, adopt the fingertip of all-in-one-piece flat U type spare structure; After the technical scheme that touch base and fingertip directly are connected through securing member; Solved the prior art spherical and contacted the problem of being brought, reached that contact is reliable, contact resistance is little and purpose such as difficult heating with aperture edge line.
The 2nd, after clamping plate are set up in flat U type spare periphery; Not only make the thickness attenuation relatively of fingertip; Help reducing manufacture difficulty and cost, and be in operation, have better affinity under the supplemental support of clamping plate between fingertip and moving contact; And this affinity helps to reduce contact resistance, prolongs fingertip useful life.
The 3rd, set up a bump contacted chip, an end of brace is locked by securing member with a joint face of said flat U type spare, clamping plate and touch base link into an integrated entity, increased area of dissipation.
For deepening that understanding of the present invention is made further detailed description below in conjunction with accompanying drawing through embodiment.
