Description
Technical field
The utility model relates to the plum blossom contact for switching fastening spring rapid installation device that a kind of electric power system uses.
Background technology
At present, in electric power system, it is no matter 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 have prevent misoperation circuit breaker, prevent on-load shake hands stopping switch, prevent chargedly closing earthed switch, prevent earthed switch power transmission and prevent " five prevent " 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 cabinet body, and superheating phenomenon is less likely to occur.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 has direct relation, if but Mume flower contact contacts bad with fixed contact, 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 make Mume flower contact one section be fixed on car switch, 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 run under overload state, there will be contact unavoidably and burn out, this just needs to change Mume flower contact.
The used time is not a linear springs to fastening spring, and the used time is rolled into it after circle head and head are firmly linked with and is fixed on Mume flower contact again.The old way of installation tradition of Mume flower contact fastening spring is: 1), at least need three people, because fastening spring elasticity is very large, first people holds up Mume flower contact, second people makes fastening spring be rolled into circle around Mume flower contact, third people clamps two heads of linear springs respectively with two nipper plierss or screwdriver, puts forth one's strength after making it draw close and hangs over together; 2) when, installing fastening spring, firmly inequality or the excessive spring that easily makes of exerting oneself have scar or fracture; 3) spring spring bullet wound and staff is easily made as grabbed loosely spring when, installing; 4) as use instrument easily hurts the hand of installation personnel because of carelessness when, installing; 5), install that bad or not in place easily to cause contact and switch loose contact to cause overheated; 6), installation duration, add interruption duration etc.
For solving the problem, the present inventor devises a kind of plum blossom contact for switching fastening spring rapid installation device, and applied for patent, the patent No. is 201420384376.2, it is made up of spring fitting connector and spring-advance device two parts, and spring fitting connector comprises the taper type cylindrical shell and a bit of cylinder be made up of hard material.Problem is, through using, taper type cylindrical shell because surperficial smoother, the pawl of spring-advance device when advancing firmly, easily in horizontal skidding.
Summary of the invention
In order to overcome above-mentioned difficulties, the utility model provides a kind of plum blossom contact for switching fastening spring rapid installation device, and what adopt that this device can be convenient and safe carries out Fast Installation to any plum blossom contact for switching fastening spring.
The technical scheme that solution the utility model problem adopts is: it is made up of spring fitting connector and spring-advance device two parts, spring fitting connector comprises the taper type cylindrical shell and a bit of cylinder be made up of hard material, taper type drum surface is evenly equipped with longitudinal groove, cylinder is connected to the large one end of taper type barrel diameter, drum diameter is more bigger than plum blossom contact for switching diameter, can be enclosed within 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 the spring of somewhat resilient on supporting bracket edge and pawls by connecting supporting bracket and being evenly fixed on and form, connect supporting bracket diameter and be slightly less than drum diameter, spring lower end of pawling is provided with a little pressing plate turned up, and each spring is pawled and is all in corresponding longitudinal groove.
Longitudinal groove on taper type cylindrical shell is the groove that punching press is formed.
Longitudinal groove on taper type cylindrical shell is the groove be folded to form.
Good effect of the present utility model is: structure is simple, easily makes, with low cost, and handling safety is easy to carry; Singlely can to operate, camber of spring can not be made, disconnect or cause scar, spring spring bullet can not be made to cause danger, the injury that operator points can not be caused; Spring is pawled when exerting oneself downwards, can not laterally skid; Install respond well, attractive in appearance, and installation effectiveness is high.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model using state schematic diagram.
Embodiment
As shown in Figure 1, it is made up of spring fitting connector 2 and spring-advance device 1 two parts the utility model, can be designed to Multiple Type as required, to be applicable to the switch of different model.Spring fitting connector 2 comprises the taper type cylindrical shell 5 and a bit of cylinder 9 be made up of hard material, cylinder 9 is connected to the large one end of taper type cylindrical shell 5 diameter, cylinder 9 diameter is more bigger than plum blossom contact for switching diameter, and length is 50mm, can be enclosed within Mume flower contact.Taper type cylindrical shell 5 is folded by a fanning strip or rectangular slab and forms, and the inner of fanning strip is radially cut into strip, or rectangular slab one end is cut into bar, then fold up each one by one and fix, namely form the taper type cylindrical shell of surface band groove 4; One end diameter that taper type cylindrical shell 5 diameter is little is less than the inner ring of Mume flower contact fastening spring; Spring-advance device 1 connects four springs of somewhat resilient on supporting bracket edge and pawls by connecting supporting bracket and being evenly fixed on and 3 to form, connect supporting bracket diameter and be slightly less than drum diameter, it 3 is bar steel plates of a wide 15mm that spring is pawled, the seam of a long 15mm vertical direction is opened in the middle of lower end, lower end is divided into two, to translate into a little pressing plate 6 outside a slice wherein, valgus angle is not more than 90 degree, is polished smooth and becomes a little fixing card 7 by another sheet lower end sharpening.
Concrete operation step is: staff according to the size of switch contact rated capacity size and Mume flower contact, can select suitable Mume flower contact fastening spring rapid installation device.First will the Mume flower contact fastening spring 8 installed be needed to be rolled into circle and to be firmly linked with at two, being inserted in from the little head end of spring fitting connector 2 is enclosed within taper type cylindrical shell 5, again four of spring-advance device 1 springs are pawled on the 3 taper type cylindrical shells 2 be also enclosed within spring fitting connector 2, the taper type cylindrical shell 5 of spring fitting connector 2 is close to by the little fixing card 7 of 3 lower ends of being pawled by spring, be placed in corresponding groove 4, insert inside Mume flower contact fastening spring 8, spring is pawled the little pressing plate 6 pressing spring circle on 3 little fixing card 7 sides, lower end, operator promotes spring-advance device 1, spring is pawled and 3 to be travelled forward along groove 4, the cylinder 9 Mume flower contact fastening spring 8 being shifted onto spring fitting connector 2 end rest on herein, can successively many Mume flower contact fastening springs 8 be advanced and rest on cylinder 9.Then the cylinder 9 of spring fitting connector end is enclosed within Mume flower contact, continues to promote spring-advance device 1, namely Mume flower contact fastening spring 8 is pushed on Mume flower contact, complete installation.
