Description
Technical field:
The present invention relates to a kind of power transmission and transformation fields, replace new exclusive equipment more particularly to a kind of switchgear moving contact spring.
Background technique:
With the further development in city and constantly improve for electric system, Power System Security And Reliability has seemed more and more heavier
It wants.Substation's quantity increases comparatively fast, and respective switch cabinet quantity increases rapidly, and switchgear quantity is more, high failure rate, wherein moving contact
Contacted between static contact it is not tight caused by equipment fault endanger most serious, in the recent period it occur frequently that since dynamic/static contact contact is not made tightly
It generates heat at switch cabinet contact, leads to the accident of switchgear scaling loss.Currently, since switchgear dynamic/static contact is located inside switch cabinet,
When touch spring aging fatigue, failure is difficult to find, and since spring compression dynamics is big when replacing touch spring, causes replacement tired
Difficulty, consuming time is long, and person works' amount is big.In switchgear day-to-day operation maintenance from now on, switch cabinet contact is actively developed
The spring of aging fatigue is replaced in spring fatigue degree inspection in time, it is ensured that is contacted closely between dynamic/static contact, is avoided generating heat
Caused by failure deteriorate, cause switchgear accident occur.
Replacement moving contact spring mostly uses greatly the common tools such as screwdriver, tool tong to drive support spring into capable replacement at present.
Since spring compression dynamics is big, entire replacement process needs multidigit service personnel to complete jointly, and leading to conventional method, time-consuming, work
It measures more heavy.It is more and more in view of switchgear quantity, this increasing development trend of line service amount, existing side
Method is difficult to the problem of mass disposal moving contact spring fatigue aging.Therefore, it is necessary to develop a kind of switchgear moving contact replacement
New exclusive equipment, to effectively solve the problems, such as that replacement heavy workload, time-consuming, replacement difficulty is big, it is ensured that switchgear operation
Operating condition is good.
Summary of the invention:
The technical problems to be solved by the present invention are: overcome the deficiencies of the prior art and provide it is a kind of using flip-chip fashion, by circular cone
The bottom alignment moving contact of shape structure, new moving contact spring is inserted in from conical tip, realizes one to moving contact spring
Carry out quick-replaceable switchgear moving contact spring replacement new exclusive equipment.
The technical scheme is that a kind of switchgear moving contact spring replaces new exclusive equipment, including fixing body, institute
Stating fixing body is conical structure made of epoxide resin material, and the bottom of its conical structure is arcuate structure, and is arranged
Have and realize the connection structure being detachably connected with moving contact, and the bottom of the conical structure is provided with annular anti-skid bulge.
The connection structure is the groove being used cooperatively with moving contact.
The beneficial effects of the present invention are:
1, the present invention uses flip-chip fashion the cone fixing body made of epoxide resin material, by the bottom of conical structure
Portion is directed at moving contact, and new moving contact spring is inserted in from conical tip, realizes that one carries out quickly more moving contact spring
Operation is changed, working efficiency is improved.
2, the present invention is the conical structure made of epoxide resin material, and production is simple and fast, is provided with simultaneously
Annular anti-skid bulge prevents spring from rebounding outside push-on process is favorite, and installation process is safer, laborsaving.
3, fixing body of the present invention is mounted on moving contact by the groove cooperated with moving contact using flip-chip fashion, convenient
Disassembly, while fixing body is an integral molding structure, convenient for carrying out Matching installation with moving contact.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram that switchgear moving contact spring replaces new exclusive equipment.
Fig. 2 is the mounting structure schematic diagram of A in Fig. 1.
Specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, in figure, 1- fixing body, 2- arcuate structure, 3- annular anti-skid bulge, 4- moving contact, 5- is dynamic
Touch spring.
Switchgear moving contact spring replaces new exclusive equipment, including fixing body 1, and fixing body 1 is epoxide resin material system
At conical structure, and the bottom of its conical structure be arcuate structure 2, and be provided with moving contact realization be detachably connected
Connection structure, and the bottom of conical structure is provided with annular anti-skid bulge 3.Connection structure is used cooperatively with moving contact
Groove (is not drawn into) in figure.
In use, matched fixing body 1 is selected according to moving contact 4, by the groove on fixing body 1 fixing body 1
Be nested on moving contact 4, new moving contact spring 5 be inserted in from the conical tip of fixing body 1, moving contact spring 5 from it is small to
Greatly, from pine to tightly being pushed into bottom, that is, to be installed in place.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, still falls within
In the range of technical solution of the present invention.
Claims (2)
