Abstract
The utility model discloses a kind of switchgear moving contact springs to replace new exclusive tool, including fixing body, fixing body is conical structure made of epoxide resin material, and the bottom of its conical structure is arcuate structure, and it is provided with and realizes the connection structure being detachably connected with moving contact, and the bottom of conical structure is provided with annular anti-skid bulge.Connection structure is the groove being used cooperatively with moving contact；The utility model uses flip-chip fashion the cone fixing body made of epoxide resin material, by the bottom alignment moving contact of conical structure, new moving contact spring is inserted in from conical tip, realizes that one carries out quick-replaceable operation to moving contact spring, improves working efficiency.
Description
Technical field:
The utility model relates to a kind of power transmission and transformation fields, novel specially more particularly to a kind of replacement of switchgear moving contact spring
Use tool.
Background technique:
With the further development in city and constantly improve for electric system, Power System Security And Reliability has seemed more next
It is more important.Substation's quantity increases comparatively fast, and respective switch cabinet quantity increases rapidly, and switchgear quantity is more, high failure rate, wherein moving
Contacted between contact and static contact it is not tight caused by equipment fault endanger most serious, in the recent period it occur frequently that not due to dynamic/static contact contact
Tightly switch cabinet contact is caused to generate heat, leads to the accident of switchgear scaling loss.Currently, since switchgear dynamic/static contact is located in switchgear
Portion, when touch spring aging fatigue, failure is difficult to find, and since spring compression dynamics is big when replacing touch spring, causes to replace
Difficulty, consuming time is long, and person works' amount is big.In switchgear day-to-day operation maintenance from now on, switchgear touching is actively developed
Head spring fatigue degree inspection, replaces the spring of aging fatigue in time, it is ensured that contacts closely between dynamic/static contact, avoids sending out
Failure caused by heat deteriorates, and switchgear accident is caused to 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 tool, 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.
Utility model content:
The technical problem to be solved by the utility model is to overcoming the deficiencies of the prior art and provide a kind of using upside-down mounting shape
New moving contact spring is inserted in by formula by the bottom alignment moving contact of conical structure from conical tip, realizes one to dynamic
Touch spring carries out quick-replaceable switchgear moving contact spring and replaces new exclusive tool.
The technical solution of the utility model is: a kind of switchgear moving contact spring replacement new exclusive tool, including installation
Body, the fixing body is conical structure made of epoxide resin material, and the bottom of its conical structure is arcuate structure, and
It is provided with and realizes the connection structure that is detachably connected with moving contact, and to be provided with annular anti-skidding convex for the bottom of the conical structure
It rises.The connection structure is the groove being used cooperatively with moving contact.
The beneficial effects of the utility model are:
1, the utility model uses flip-chip fashion the cone fixing body made of epoxide resin material, will be conical
The bottom alignment moving contact of structure, new moving contact spring is inserted in from conical tip, realize one to moving contact spring into
The operation of row quick-replaceable, improves working efficiency.
2, the utility model is the conical structure made of epoxide resin material, and production is simple and fast, while setting thereon
It is equipped with annular anti-skid bulge, prevents spring from rebounding outside push-on process is favorite, installation process is safer, laborsaving.
3, the utility model fixing body is mounted on moving contact by the groove cooperated with moving contact using flip-chip fashion,
It is easy to disassemble, 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 tool.
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- moving contact spring.
Switchgear moving contact spring replaces new exclusive tool, 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 descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
Claims (2)
1. a kind of switchgear moving contact spring replaces new exclusive tool, including fixing body, it is characterized in that: the fixing body is ring
