Abstract
A kind of power transmission and transformation line escapement, belong to power transmission and transformation field, comprise insulator, adjustable bolt, the insulator string that described escapement is connected in series by multiple insulator, described insulator string two ends respectively connected adjustable bolt, other one end of adjustable bolt is connected to the fixed hook that can fixedly hang on electric wire, utilize between this circuit can avoiding causing because of strong wind etc. and contact, thus cause line short problem, the device damage because short circuit causes can be avoided further, the amplitude of fluctuation of circuit can be reduced, reduce because circuit swings the electric pole caused, steel towers etc. tilt or the generation of accident such as to topple over.
Description
Technical field
The utility model relates to a kind of cable space device, and particularly a kind of power transmission and transformation line escapement, belongs to power transmission and transformation field.
Background technology
In power transmission and transformation line, the distance of circuit depends on the distance on electric pole, steel tower between circuit, but, sometimes because the reason of wind, can make to produce between electric wire to swing, there is the danger of short circuit between electric wire, in order to make to maintain a certain distance between electric wire, need the escapement arranged between holding circuit, but, in line segregation device in the past, certain position can not be fixed on, interval keeps having certain unsteadiness, therefore, needs a kind of power transmission and transformation line cable space device keeping line segregation in fixed position.
Summary of the invention
The problem of interval instability in the danger of short circuit and power transmission and transformation line can be caused for electric wire swing in power transmission and transformation line, the utility model provides a kind of power transmission and transformation line escapement, its objective is the danger reducing the line member contact that circuit causes due to strong wind etc., it is the spacing that circuit keeps certain, improve the safe coefficient of power transmission and transformation line, ensure circuit mesohigh electricity normal conveying.
The specific embodiment that the utility model is taked is: a kind of power transmission and transformation line escapement, comprise insulator, adjustable bolt, the insulator string that described escapement is connected in series by multiple insulator, described insulator string two ends respectively connected adjustable bolt, other one end of adjustable bolt is connected to the fixed hook fixedly hung on electric wire, the other end of described fixed hook is screw rod, screw rod is provided with a nut, nut is connected to the compressing member compressing electric wire, further, the both ends of described adjustable bolt are provided with the fixing hole for fixed intervals device when regulating length, further, joint is provided with between described adjustable bolt and insulator string.
The good effect that the utility model has contacts between the circuit that can avoid causing because of strong wind etc., thus cause line short problem, the device damage because short circuit causes can be avoided further, the amplitude of fluctuation of circuit can be reduced, reduce because circuit swings the generation that the electric pole, steel tower etc. that cause tilt or the accident such as to topple over.
Accompanying drawing explanation
Fig. 1 overall schematic of the present utility model.
The schematic diagram of fixed hook in Fig. 2 the utility model.
Embodiment
Be described with regard to concrete scheme of the present utility model referring to Fig. 1, Fig. 2.In figure, M-left-half, N-right half part, 1-insulator string, 2-joint, 3-fixing hole A, 4-adjustable bolt, 5-fixing hole B, 6-fixed hook, 7-set bolt, 21-drag hook, 22-spring guard, 23-nut, 24-compressing member, 25-screw rod.
Be erected in the power transmission and transformation line on electric pole and steel tower, if time electric wire span is large, can because of reasons such as typhoons, cause the unordered swing between electric wire, in order to prevent the swing of electric wire, cause short circuit or electric pole, waving of steel tower, cause potential safety hazard, this power transmission and transformation line escapement insulator, adjustable bolt, described power transmission and transformation line escapement is made up of symmetrical left-half M and right half part N, described escapement is the insulator string 1 be connected in series by multiple insulator, described insulator string 1 two ends respectively connected adjustable bolt 4, joint 2 is utilized to be connected between adjustable bolt with insulator string 1, other one end of adjustable bolt 4 is connected to the fixed hook 6 that can fixedly hang on electric wire, the both ends of described adjusting bolt are provided with when regulating length for fixed intervals device or for the A fixing hole 3 of control interval device length and B fixing hole 5, the screw rod 25 of described fixed hook and the screw rod of adjustable bolt 4 are integrated.Referring to Fig. 2 with regard to fixed hook, in described fixed hook 6, there is hook 21, on electric wire during hook, dead spring guard 22, after hanging up properly, nutting 23, the compressor arm 24 be connected with nut is moved toward electric wire direction, when compressor arm 24 and electric wire are to after contacting, fixed hook 4 will be fixed on electric wire, even if there is typhoon etc. to blow, fixed hook also can not shift position, the interval of electric wire can be stabilized in a corresponding position.
Contact between the circuit utilizing this line segregation device can avoid causing because of strong wind etc., thus cause line short problem, the device damage because short circuit causes can be avoided further, the amplitude of fluctuation of circuit can be reduced, reduce because circuit swings the generation that the electric pole, steel tower etc. that cause tilt or the accident such as to topple over.
