Abstract
A kind of power cable radius of turn tester.It is box structure, and on it, four sides and bottom surface are plane, and end face is the arcwall face raised up.The radius-of-curvature of described end face is 1000-1500mm.In four described sides, two relative side lower are formed with a hand-held square hole respectively.The power cable radius of turn tester that the utility model provides has reasonable in design, simple, simple to operate, the advantage such as be easy to carry, be specially adapted to job site personnel to turning of cable radius whether at design radius of turn zone of reasonableness control.
Description
Technical field
The utility model belongs to technical field of electric power, particularly relates to a kind of power cable radius of turn tester.
Background technology
In electric system, because the external diameter of power cable is comparatively large, therefore comparatively difficult when transport, power cable laying.Particularly in the work progress of power cable, require stricter to the radius of turn of power cable, if power cable angle of turn is excessive, the conductor of its inside is probably made to be subject to mechanical damage, and mechanical damage can be covered by the insulation course of outside and cannot see, even if therefore adopt measuring circuit resistance, insulation and leakage test to be also difficult to find defect, then easily overheated at impaired place and cable insulation intensity is declined, until break down during operation.
At present, the radius of turn of actual measurement power cable mainly adopts the measuring method such as " action method ", " three point method ", because the computing formula of these methods is comparatively complicated, but also need by aids such as tape measure, white line, iron wires, therefore extremely bother, particularly site operation personnel often do not possess measuring and calculating ability, therefore measuring and calculating is not gone in a lot of situation, only operate by rule of thumb, the problems such as result easily causes the not enough or angle of turning of cable radius excessive, thus greatly reduce the serviceable life of cable, even cause power cable fault.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of power cable radius of turn tester.
In order to achieve the above object, the power cable radius of turn tester that the utility model provides is box structure, and on it, four sides and bottom surface are plane, and end face is the arcwall face raised up.
The radius-of-curvature of described end face is 1000-1500mm.
In four described sides, two relative side lower are formed with a hand-held square hole respectively.
The power cable radius of turn tester that the utility model provides has reasonable in design, simple, simple to operate, the advantage such as be easy to carry, be specially adapted to job site personnel to turning of cable radius whether at design radius of turn zone of reasonableness control.
Accompanying drawing explanation
The power cable radius of turn tester structure side view that Fig. 1 provides for the utility model.
The power cable radius of turn tester using state structure side view that Fig. 2 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the power cable radius of turn tester that the utility model provides is described in detail.
As shown in Figure 1, the power cable radius of turn tester 1 that the utility model provides is box structure, and on it, four sides and bottom surface are plane, the arcwall face of end face 2 for raising up.
The radius-of-curvature of described end face 2 is 1000-1500mm.
In four described sides, two relative side lower are formed with a hand-held square hole 3 respectively, are convenient to carrying like this.
The power cable radius of turn tester using method now provided by the utility model is described below: when needing the radius of turn measuring bending part on power cable in work progress, as shown in Figure 2, first by site operation personnel, the camber line of the bending part on power cable 4 along end face 2 is moved towards to be placed on the end face 2 of this power cable radius of turn tester 1, if this power cable 4 is the power cable of number in the figure A, now the intermediate point of end face 2 presses close to power cable 4, slightly gap between the two ends of end face 2 and power cable 4, illustrate that the radius of turn of this power cable 4 meets and lay requirement, if and this power cable 4 is the power cable of number in the figure B, now the intermediate point of end face 2 is not fitted power cable 4, and the two ends of end face 2 contact with power cable 4, illustrate that the radius of turn of this power cable 4 is less than 1000mm, therefore do not meet and lay requirement.
Claims (3)
1. a power cable radius of turn tester, is characterized in that: described power cable radius of turn tester (1) is box structure, and on it, four sides and bottom surface are plane, end face (2) arcwall face for raising up.
