Abstract

The utility model discloses a kind of 10kV overhead transmission line uninterrupted operation device, comprise: elevating mechanism; Insulator crossarm, is connected with described elevating mechanism; At least one insulated gin, is arranged on described insulator crossarm.The utility model structure is simple, practical, when the not power-off of 10kV overhead transmission line, can complete the replacing to pin insulator and cross-arm.

Description

A kind of 10kV overhead transmission line uninterrupted operation device
Technical field
The utility model relates to technical field of electric power, is specifically related to a kind of 10kV overhead transmission line uninterrupted operation device.
Background technology
Last century the fifties, China has started the beginning of 3.5kV distribution line live working, and along with expanding economy, live line working has become the routine techniques means ensureing socio-economic development and the stable life of people's harmony.
In the operation of electric power system, harsh climate and outside destroy can produce enormous impact to the reliable power supply of 10kV circuit, thunderbolt shaft tower causes pin insulator to puncture, outside destroy causes wire cross-arm metaboly to happen occasionally, and replacing cross-arm and pin insulator have two kinds of methods at present:
Method one, line outage is repaired, and its shortcoming to cause user and enterprise to have a power failure, and reduces the power supply reliability of circuit, reduce economic benefit;
Method two, adopt aerial lift device with insulated arm live line working to recover, its shortcoming is that aerial lift device with insulated arm can limit by self load bearing factor, is difficult to mention aerial condutor, cannot implement the operation of restringing cross-arm.
Utility model content
The purpose of this utility model is to provide a kind of 10kV overhead transmission line uninterrupted operation device, and structure is simple, practical, when the not power-off of 10kV overhead transmission line, can complete the replacing to pin insulator and cross-arm.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of 10kV overhead transmission line uninterrupted operation device, is characterized in, comprises:
Elevating mechanism;
Insulator crossarm, is connected with described elevating mechanism;
At least one insulated gin, is arranged on described insulator crossarm.
The quantity of described insulated gin is 3.
Described insulated gin is connected with described insulator crossarm by rivet.
The expansion link that described elevating mechanism comprises base and is vertically arranged on base;
Described expansion link is connected with described insulator crossarm, and described expansion link is arranged with described insulator crossarm is mutually vertical.
Described elevating mechanism comprises a support column further, and described support column is arranged between described base and expansion link.
Described elevating mechanism comprises one first reinforcement further, is arranged between the radial direction of insulator crossarm and the angle of expansion link axis.
Described elevating mechanism comprises several the second reinforcements further, is arranged between the radial direction of base and the angle of support column axis.
The quantity of the second described reinforcement is 4.
Several described second reinforcements divide equally the circumference shared by base.
A kind of 10kV overhead transmission line of the utility model uninterrupted operation device compared with prior art has the following advantages: owing to being provided with expansion link and being arranged on the insulated gin on insulator crossarm, conveniently overhead wire is mentioned, make overhead wire depart from cross-arm on electric pole, thus make power construction personnel can complete replacing to cross-arm on electric pole when overhead wire not power-off.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of 10kV overhead transmission line of the utility model uninterrupted operation device;
Fig. 2 is that the utility model implements illustration.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of 10kV overhead transmission line uninterrupted operation device, comprises: elevating mechanism; Insulator crossarm 1, is connected with described elevating mechanism; At least one insulated gin 2, is arranged on described insulator crossarm 1; The expansion link 4 that described elevating mechanism comprises base 3 and vertically arranges on the base 3; Expansion link 4 is arranged with insulator crossarm 1 is mutually vertical, and preferably, expansion link 4 adopts hydraulically extensible bar.
In preferred embodiment of the present invention, the quantity of insulated gin 2 is 3, and insulated gin 2 is connected with described insulator crossarm 1 by rivet 5.
Preferably, in preferred embodiment of the present invention, elevating mechanism also comprises a support column 6, and described support column 6 is arranged between described base 3 and expansion link 4.
Preferably, in preferred embodiment of the present invention, elevating mechanism also comprises one first reinforcement 7, is arranged between the radial direction of insulator crossarm 1 and the angle of expansion link 4 axis.
Preferably, in preferred embodiment of the present invention, elevating mechanism also comprises several the second reinforcements 8, is arranged between the radial direction of base 3 and the angle of support column 6 axis.
Preferably, in preferred embodiment of the present invention, the quantity of the second reinforcement 8 is 4, and 4 the second reinforcements 8 divide equally the circumference shared by base 3.
Embodiment, as shown in Figure 2, by controlling the flexible of expansion link 4, make the notch height of insulated gin 2 consistent with the height of overhead wire 9, then by movable base 3 and support column 6, overhead wire 9 is made to stick in the notch of insulated gin 2, finally by the stretching, extension controlling expansion link 4, under the effect of insulator crossarm 1 and insulated gin 2, overhead wire 9 is mentioned, make overhead wire 9 depart from cross-arm 11 on electric pole 10, thus make power construction personnel can complete replacing to cross-arm 11 on electric pole 10 when overhead wire 9 not power-off; After electric pole 10 cross tube 11 has been changed, by controlling the contraction of expansion link 4, overhead wire 9 to be set up again on pin insulator 12.
The utility model achieves when the not power-off of 10kv overhead transmission line, completes the replacing to pin insulator 12 and cross-arm 11, thus ensure that the electricity consumption of user and enterprise, contributes to the speed improving power construction simultaneously.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection range of the present utility model should be limited to the appended claims.
