Abstract
The invention relates to a spring disassembling tool of a 10 kV circuit breaker mechanism. The center of a connecting part is provided with a thread sleeve; one end of a thread rod penetrates the thread sleeve to be fixedly connected with a base; each end of the connecting part is connected with a spring fork through a shaft pin; the two spring forks move freely on the axis of the connecting part; a connecting plate is fixed between the base and each spring fork through the corresponding shaft pin. According to the spring disassembling tool of the 10 kV circuit breaker mechanism, the working efficiency of maintenance and fault treatment on a 10 kV circuit breaker is effectively improved, the risk of the damage to the substation maintenance professional staff is avoided, only simple machining needs to be performed on an original part, the structure is simple, the cost is low, and the tool can be repeatedly used.
Description
Technical field
The present invention relates to a kind of electric power system substation equipment maintenance and repair instrument, relate in particular to a kind of 10kV breaker mechanism spring assembling/disassembling tool, for 10kV overhaul of line breaker, fault, get rid of, belong to T & D Technology field.
Background technology
10kV circuit breaker exists quantity more in electric power system, 10kV circuit breaker is overhauled or the process of troubleshooting in, often need its in-house spring of dismounting, original dismounting spring method used is very loaded down with trivial details, with many, utilize manpower by spring distending the instruments such as screwdriver, and remain on energy storage state and spring could be pulled down, the method time is long, efficiency is low, so interruption duration that need to be longer; And because the elastic potential energy of mechanism's inner spring is very large, if controlled, with great difficulty substation equipment maintenance and repair professional is not damaged, potential risk is high.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of 10kV breaker mechanism spring assembling/disassembling tool is provided, solved in electric power system that 10kV circuit breaker overhauls and during troubleshooting efficiency low, there is the problem of potential safety hazard, shortened interruption duration.
Technical scheme of the present invention is as follows.
Connector center is threaded cover, and one end of threaded rod is fixedly linked through thread bush and base; The two ends of connector are connected with spring fork respectively by pivot pin, and two spring forks freely move on the axis of connector; Connecting plate is fixed between base and spring fork by pivot pin.
The external screw thread of described threaded rod and connector thread bush internal thread match.
Described threaded rod other end termination is provided with rotation jack.
Described base and connector square crossing.
The two ends of described base are provided with fixed head.
Described one end of winning in succession is fixed on base fixing plate, and the other end of winning in succession is fixed on spring fork sidewall.
Described spring fork is symmetricly set on the two ends of connector.
Tool of the present invention has the following advantages:
Utilize cooperation and the connection of swivel nut and screw rod, compare with the method for original dismounting 10kV breaker mechanism inner spring, can find out the way that forces spring distending by mechanical control ratio manpower plug rigidity object, fail safe has obvious lifting, has saved the time simultaneously.Therefore the present invention has effectively improved 10kV circuit breaker has been overhauled and operating efficiency during troubleshooting, has evaded the risk that substation equipment maintenance and repair professional is damaged.And this instrument carries out simple processing to original paper can be completed, simple in structure, with low cost, can Reusability.

In figure, 1, spring fork, 2, threaded rod, 3, connector, 4, base, 5, win in succession, 6, pivot pin, 7, jack.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe concrete structure of the present invention in detail.
Embodiment
As Figure 1-3, connector 3 centers are threaded cover, base 4 is arranged on below and the connector square crossing of connector, the two ends of base are provided with fixed head, one end of threaded rod 2 is fixedly linked through thread bush and base center, threaded rod other end termination is provided with rotates jack 7, and the external screw thread of threaded rod and connector thread bush internal thread match; The two ends of connector 3 are connected with spring fork 1 respectively by pivot pin 6, and two spring forks are symmetricly set on the two ends of connector, and two spring forks freely move on the axis of connector; Described one end of 5 of winning in succession is fixed on base fixing plate by pivot pin, and 5 other ends of winning in succession are fixed on spring fork sidewall by pivot pin.
The present invention utilizes the cooperation of threaded rod and thread bush to realize 2 objects, and the one, have firm effectively gradually by the function of 10kV breaker mechanism inner spring distending; Secondly after spring is by distending, its energy storage state of maintenance that can be good.
During use, spring fork 1 is pitched to the two ends into 10kV breaker mechanism inner spring, then rotate threaded rod 2, threaded rod 2 moves to base 4 directions by the cooperation of the thread bush at connector 3 centers.Because of relative fixing with the position of threaded rod 2 ends in base 4, so the gap between base 4 and connector 3 is becoming large gradually, and the length of connecting plate 5 is fixed, by the distance between two spring clips under the effect of each pivot pin 6, increasing, can make thus spring distending gradually, and can make spring stable remain on energy storage state, distending put in place can be safe and reliable while meeting knocked down condition this state that remains on, substation equipment maintenance and repair professional can conveniently pull down spring.Otherwise, during installation, form therewith contrary.
