Description
Technical field
The utility model is a kind of multifunctional assembled insulating bar, and its end construction can combining and interchanging, can be used for anchor support wire jumper sag and measures; Can be used for porcelain insulator and survey zero; Also can be used for extracing multiple function such as kite on the high-tension line.
Background technology
The electric clearance of transmission line of electricity wire jumper and each parts of shaft tower need satisfy certain safe distance requirement.When before new line puts into operation, carrying out an acceptance inspection at present, the measurement of the wire jumper sag of anchor support is generally measured with the insulation hook stick, and this hook stick is relatively heavier, do not have scale, not directly perceived, efficiency is low, precision is low, does not meet the requirement of current lean management.In recent years, Nanjing transmission line of electricity that electric company has jurisdiction over had taken place several successively because anchor support wire jumper sag distance is excessive, caused lead to body of the tower generation windage yaw tripping operation fault, badly influenced the safe and reliable operation of electrical network.Find that when carrying out accident analysis it is the immediate cause that causes fault to take place that the wire jumper sag does not meet designing requirement.So, how to improve wire jumper sag surveying work, improve its certainty of measurement, make its requirement of satisfying design document, be the difficult problem that the circuit operations staff faces.
Along with the raising of living standards of the people, the situation that the spare time resident goes out to fly a kite is very general, and especially at spring and autumn, the annual situation that a lot of kite coilings all can take place under the situation of wet weather, even can cause the line fault tripping operation.Remove the key of kite and extract the kite string that is wrapped on the lead wire and earth wire in time.The kite string good toughness easily twines, and is difficult to break, if misoperation may cause the swing of power transmission line when breaking kite string, causes more serious accident.How to remove kite string under the situation that does not influence the normal operation of power transmission line, be the problem that needs are handled.
How the convenient safe operation problem that solves above-mentioned transmission line of electricity safely and effectively is worth research.
Summary of the invention
Problem to be solved in the utility model is: develop a kind of knockdown operation tool, both can measure anchor support wire jumper sag very easily, also can extract the kite string that is wrapped on the high-tension line, simultaneously existing porcelain insulator is surveyed zero device and also made up, address the above problem safely and effectively.
The technical solution of the utility model is: the multifunction insulating rod, comprise insulating bar and tool heads, and the first end of instrument is connected with insulating bar, and an end is unsettled, and tool head separates cutting edge of a knife or a sword and becomes cutter, and free end is not opened cutting edge of a knife or a sword at least.
The utility model also comprises the short circuit fork, and tool heads and insulating bar flexibly connect, and described short circuit fork and insulating bar flexibly connect, and tool heads and commutative being connected on the insulating bar of short circuit fork are used.For realizing the measurement to anchor support wire jumper sag, insulating bar subscript of the present utility model is marked with scale.
The utility model preferred version is: tool heads is that sickle is hook-shaped, and the hook-shaped inboard pars intermedia of sickle separates cutting edge of a knife or a sword and becomes cutter.The hook-shaped tool heads of sickle is convenient to hook the kite string that is wrapped on the transmission line of electricity, because the free end of tool heads is not opened cutting edge of a knife or a sword, can not cause damage to power transmission line in the hook kite string, partly cuts off kite string with the tool heads cutter then and gets final product.When measuring anchor support wire jumper sag, the hook-shaped tool heads of sickle also can help insulating bar to locate between wire jumper and body of the tower, improves accuracy of measurement.Insulating bar is a Collapsible structure, makes things convenient for carrying and operating of personnel.Also tool heads can be changed into the short circuit fork simultaneously, directly porcelain insulator be carried out and surveyed the odd-job work.
The utility model is simple and easy to realize, safe and convenient to use, can under the situation that does not influence the normal operation of lead, remove kite string, also can measure simultaneously anchor support wire jumper radian, or porcelain insulator is carried out the survey odd-job do, a device can be finished multinomial work; Volume is little, and cost is low, is equipped with for the staff with oneself, helps the maintenance work of staff to transmission line of electricity.
Description of drawings
Fig. 1 connects the structure chart of the hook-shaped tool heads of sickle for the utility model insulating bar.
Fig. 2 connects the structure chart of short circuit fork for the utility model insulating bar.
The specific embodiment
As Fig. 1, the utility model insulated hook rod comprises insulating bar 1 and the hook-shaped tool heads 2 of sickle, the inboard of the hook-shaped tool heads 2 of sickle, and pars intermedia separates cutting edge of a knife or a sword and forms cutter 3; Insulating bar 1 is marked with scale, and can stretch.
When removing kite string, operating personnel hand insulating bar, hook the kite string that will cut off with the hook-shaped tool heads of sickle, partly cut off kite string with cutter, the hook-shaped tool heads of sickle is convenient to hook the kite string of winding, and the tool heads free end is not opened cutting edge of a knife or a sword, in the hook line, can not cause damage to transmission line of electricity, cutter is positioned at the hook-shaped tool heads of sickle inboard, also can not draw power transmission line during secant by mistake, cuts off the malfunction that kite string also can not cause power transmission line with cutter; Insulating bar has guaranteed operating personnel's handling safety, is mainly used in the removing of kite and kite string on 110kV and the 35kV circuit.
When the utility model was used as the measurement of anchor support wire jumper sag, the physical characteristic of its insulating bar need have good electrical insulation properties, high mechanical properties, has advantages such as hygroscopicity is low, ageing-resistant simultaneously.For the convenience of field operation, also answer light weight, easy to operate, not fragile, therefore with glass fibre, epoxy resin and coupling agent main component as formation insulation measurement rod.The physical characteristic of the utility model insulating bar is specific as follows:
1. electricity function index requirement
Specific volume resistance (Ω .cm) normality 〉=1.0 * 10
12
Immersion 〉=1.0 * 10
