Abstract
A quick installation device for a clamping spring of a plum blossom contact of a switch is composed of a spring installation connection piece and a spring pushing device. The spring installation connection piece comprises a frustum-shaped barrel and a small section of cylinder. The cylinder is connected to the large-diameter end of the frustum-shaped barrel. The diameter of the cylinder is slightly larger than the diameter of the plum blossom contact of the switch, so the plum blossom contact can be sleeved with the cylinder. The diameter of the small-diameter end of the frustum-shaped barrel is smaller than that of an inner ring of the clamping spring. The spring pushing device is composed of a connection supporting plate and spring pushing pawls, wherein the spring pushing pawls are evenly fixed to the edge on one side of the connection supporting plate and have slight elasticity. The diameter of the connection supporting plate is slightly smaller than the diameter of the cylinder. An outwards-turned small pressing plate is arranged at the lower end of each spring pushing pawl. The quick installation device has the advantages of being simple in structure, easy to manufacture, low in cost, safe in operation, convenient to carry, capable of being operated by one person, incapable of making the spring deform or break or be scarred, incapable of making the spring jump and cause danger, incapable of hurting the fingers of an operator, good and attractive in installation effect and extremely high in installation efficiency.
Description
Technical field
The present invention relates to the plum blossom contact for switching fastening spring rapid installation device that a kind of electric power system is used.
Background technology
At present, in electric power system, no matter be the 10kV switch cubicle of power plant or electric substation's (station), major part is all the middle-placed switch cabinet of KYN series, this switch cubicle can meet the standard-requireds such as GB3906, IEC298, and has the misoperation of preventing circuit breaker, prevents on-load handle stopping switch, prevents chargedly closing earthed switch, prevents earthed switch power transmission and prevent " five the is anti-" functions such as mistakenly entering charged chamber when earthing position.The major part of this switch cubicle configuration is all car switch, and car switch can shift out switch cubicle, and the contact on this switch is all the contact of plum blossom-shaped, and such contact contacts better with switch cubicle body, is not easy to occur superheating phenomenon.Mume flower contact comprises contact, bracing frame, fastening spring, spring touch finger, Mume flower contact and Switch main body and fixed contact contact quality and fastening spring have direct relation, if but that Mume flower contact contacts with fixed contact is bad, it is overheated easily to cause, want to eliminate and overheatedly will lean on fastening spring, fastening spring is arranged on the outer ring of Mume flower contact, and one section of Mume flower contact is fixed on car switch, and one section makes Mume flower contact contact well with moving contact.Due to present 10kV overload, be in all the year round at full capacity in addition or overload state under move, there will be unavoidably contact to burn out, this just need to change Mume flower contact.
Fastening spring not the used time be a linear springs, the used time is rolled into circle head it and is fixed on Mume flower contact after being firmly linked with head again.The installation of Mume flower contact fastening spring by the old way of tradition is: 1), at least need three people, because fastening spring elasticity is very large, first people is holding up Mume flower contact, second people makes fastening spring be rolled into circle around Mume flower contact, the third people clamps respectively two statures of linear springs with two nipper plierss or screwdriver, put forth one's strength after it is drawn close and hang over together; 2) while, fastening spring being installed, firmly uneven the or excessive spring that easily makes of exerting oneself has scar or fracture; 3) while, installing, as grabbed not firm spring, easily make spring spring bullet wound and staff; 4) while, installing as use instrument easily hurts the hand of installation personnel because of carelessness; 5), install that bad or not in place easily to cause that contact and switch loose contact cause overheated; 6), installation duration, increased interruption duration etc.
Summary of the invention
In order to overcome above-mentioned difficulties, the invention provides a kind of plum blossom contact for switching fastening spring rapid installation device, what adopt that this device can be convenient and safe carries out Fast Installation to any plum blossom contact for switching fastening spring.
Solving the technical scheme that problem of the present invention adopts is: it is comprised of spring fitting connector and spring-advance device two parts, spring fitting connector comprises a taper type cylindrical shell and a bit of cylinder of being made by hard material, cylinder is connected to one end that taper type barrel diameter is large, drum diameter is than plum blossom contact for switching slightly larger in diameter, can be enclosed within on Mume flower contact, one end diameter that taper type barrel diameter is little is less than the inner ring of Mume flower contact fastening spring; Spring-advance device connects on edge of supporting bracket slightly flexible spring and pawls and form by connecting supporting bracket and being evenly fixed on, and connects supporting bracket diameter and is slightly less than drum diameter, and the spring lower end of pawling is provided with a little pressing plate turning up.
It is the stripe board of a wide 10-15mm that spring is pawled, the seam of opening a long 10-15mm vertical direction in the middle of lower end, is divided into two lower end, and a slice is wherein translated into little pressing plate outward, valgus angle is not more than 90 degree, by another sheet lower end sharpening and polish smooth and become a little fixed card.
Good effect of the present invention is: simple in structure, easily make, and with low cost, handling safety, easy to carry; Single can operation, can not make camber of spring, disconnects or cause scar, can not make spring spring bullet cause danger, the injury that can not cause operator to point; Install respond well, attractive in appearancely, and installation effectiveness is high.
Accompanying drawing explanation
Accompanying drawing 1 is used view for the present invention; Accompanying drawing 2 is spring fitting connector schematic diagram of the present invention; Accompanying drawing 3 is spring-advance device schematic diagram of the present invention; Accompanying drawing 4 is the spring of the present invention bottom enlarged drawing of pawling.
Embodiment
The present invention is as shown in accompanying drawing 1,2,3, and it is comprised of spring fitting connector (shown in Fig. 2) and spring-advance device (shown in Fig. 3) two parts, can be designed to as required Multiple Type, to be applicable to the switch of different model.Spring fitting connector (Fig. 2) comprises taper type cylindrical shell 2 and a bit of cylinder 6 of being made by hard material, cylinder 6 is connected to the large one end of taper type cylindrical shell 2 diameters, cylinder 6 diameters are than plum blossom contact for switching slightly larger in diameter, length is 50mm, can be enclosed within on Mume flower contact, one end diameter that taper type cylindrical shell 2 diameters are little is less than the inner ring of Mume flower contact fastening spring 5; Spring-advance device (Fig. 3) connects on 1 one edges of supporting bracket slightly flexible four springs and pawls and 3 form by connecting supporting bracket 1 and being evenly fixed on, connect supporting bracket 1 diameter and be slightly less than cylinder 6 diameters, it 3 is bar steel plates of a wide 15mm that spring is pawled, in the middle of lower end, open the seam of a long 15mm vertical direction, lower end is divided into two, a slice is wherein translated into a little pressing plate 4 outward, valgus angle is not more than 90 degree, by another sheet lower end sharpening and polish smooth become shown in a little fixed card 7(Fig. 4).
