Description
Technical field:
The present invention relates to a kind of 10KV distribution earth potential live operation field, particularly relate to a kind of insulator crossarm with movable arc-shaped groove.
Background technology:
At present, Guo Wang company progressively improves the requirement of power supply reliability, power supply enterprise is required to client's service standard also more and more stricter, and reduce user have a power failure area, reduce customer outage hours etc. the most feasible mode carry out exactly livewire work.Livewire work is that with high content of technology, a safe skill requires strictly, and the line maintenance method of remarkable in economical benefits.By to the research of livewire work Method and kit for and improvement, to improving livewire work efficiency, expand charged job area undoubtedly, can play good effect.Suburb of Zhengzhou is with a varied topography compared with urban district, and many charged work job site is subject to the impact insulation of landform to tremble arm car cannot be close, can not implement medial potential working, thereby often adopt earth potential working method to carry out charged work.Suburb of Zhengzhou power grid construction standard is consistent with urban district now, and 10KV main line adopts JKLYJ-240 insulated wire more, LGJ-185 bare wire weight more originally.And the lifting of the charged insulating cross-arm using is now partly to take rope band as traction, the wire that is difficult to sling, power tool is heavy in addition, has increased the weight of operating personnel's labour intensity.
Summary of the invention:
Technical problem to be solved by this invention is: overcome prior art deficiency, provide a kind of simple and reasonable, be connected firmly, elevating capacity is high and labour intensity the is low insulator crossarm with movable arc-shaped groove.
Technical scheme of the present invention is: a kind of insulator crossarm with movable arc-shaped groove, contain insulator crossarm arm, insulation supporting tube and regulating arm, on described insulator crossarm arm, be provided with fixed deep-slotted chip breaker, in described insulation supporting tube, be set with leading screw, the two threaded is combined, described leading screw upper end is connected with the lower end of a connector, the two ends, left and right of described connector are connected with one end of a described insulator crossarm arm respectively, described in each, the middle part of insulator crossarm arm is connected with one end of a described regulating arm, the other end of described regulating arm and clamp connection, described clip is fixed on the external surface of described insulation supporting tube, on the external surface of described insulation supporting tube, be also fixed with at least two fixedly buckles, described fixed card is buckled and is provided with fixedly chain, described in each, on insulator crossarm arm, be provided with movable arc-shaped groove, the other end of two described regulating arms is respectively by bolt and adjusting handle and described clamp connection, and described adjusting handle is made by aluminum alloy materials.
Described leading screw top is provided with at least one locating hole.Described insulator crossarm arm is made by epoxy resin board, and described insulation supporting tube is made by epoxy resin pipe, and described regulating arm is made by epoxy resin pipe.
The invention has the beneficial effects as follows:
1, the present invention adopts screw structure, before having solved livewire work, wire is wasted time and energy, the not portative shortcoming of live line tool heaviness in traditional slinging with rope band traction, can greatly improve earth potential live job safety coefficient and operating efficiency, reduce operating personnel's danger coefficient simultaneously.
2, on insulator crossarm arm of the present invention, be provided with movable arc-shaped groove, even if the intrinsic cross-arm inclined position of cement concrete bar causes separation nonstandard, still can use this instrument to carry out operation, thereby use very convenient.In addition, this instrument overall weight meets the requirement of the livewire work bearing capacity on 10KV cement concrete bar, and safety factor is high.
3, on regulating arm of the present invention, be provided with adjusting handle, can regulate its length, and then can effectively regulate the levelness of insulator crossarm arm.
4, the present invention have install simple and easy, cost is low, lightweight, safety factor is higher, save time, the feature such as easy to operate, it is applied widely, be particularly useful for earth potential livewire work on 10KV overhead wire concrete bar, in equal ambient conditions operation, than traditional approach, can save for 1/3 time, thereby, after popularization, there is good economic benefit.
