Abstract
The utility model discloses an anti-bounce device for a breaking lead, which comprises a spacer (1), a swinging rod (2) and a swinging hammer (3). The swinging hammer (3) is positioned on the lower end of the anti-bounce device through a device enabling the swinging hammer to move side to side relatively to the spacer on the plane direction vertical to the lead. The utility model uses the principle that the swinging hammer has an opposite swinging direction in relation to the lead swinging direction due to inertia to kill the swinging force and not produce centrifugal force, thereby effectively reducing the bounce frequency and scope. The utility model can be applicable for different wind directions. The spacer can be made into different shape according to number of breaking lead in order to be fit for the transmission line with more than two times of breaking.
Description
Technical field
The utility model relates to a kind of device that stops the circuit vibration, particularly a kind of transmission line bundle conductor anti-dance device.
Background technology
In spring, autumn, season that winter wind is bigger, when wind is to the power system transmission line lead, will produce certain power, can bring out lead thus and produce a kind of self-excited vibration, its form is brandished up and down, shape such as dragon dance.
Bundle conductor is waved than single conductor is easy.The energy of waving is very big, and the duration is also longer, in case wave, can cause transmission line short circuit, broken string, tower even large-area power-cuts, brings tremendous loss for national economy and social life.Conductor galloping in various degree all took place in the transmission line of China northeast, North China, Central China, East China and the Northwest, and solving the conductor galloping problem also is a difficult problem in the world so far.For overcoming the above problems, Chinese patent ZL94218413.0 discloses a kind of overhead transmission line bundle conductor two parallel wielded-proof device, comprise conductor spacer, swing arm and pendulum, pendulum is positioned at anti-dance device lower end and rigidly connected by swing arm and conductor spacer, this anti-dance device has reduced the conductor galloping energy to a certain extent, because the two parallel wielded-proof device weight is connected immalleable with conductor spacer firmly, though can reduce the partial vibration energy, but because centrifugal action, increased the required pulling force of swing, increase the conductor galloping number of times on the contrary, the anti-dance poor effect.Chinese patent ZL94218414.9 also discloses a kind of overhead transmission line bundle conductor integral type eccentric hammer anti-dance device, this anti-dance device is made up of conductor spacer, horizontal boom beam, tup three parts, one end and the conductor spacer of horizontal boom beam are rigidly connected, and the other end and tup are rigidly connected.The whole eccentric hammer of this anti-dance device meets weight side high wind and can cause the lead amplitude of oscillation to increase.Though more than two kinds of anti-dance devices can solve the conductor galloping problem to a certain extent, all each have their own defective, the anti-dance effect is bad; Because pendulum all is rigidly connected with the anti-dance device body, therefore, in the process of wind swing, can produce centrifugal force, increase the mechanical load of lead, reduce lead useful life.
Therefore, need a kind of transmission line bundle conductor that can effectively stop to wave, and can reduce the centrifugal force that conductor galloping produces, reduce and wave frequency and amplitude, can adapt to the anti-dance device of different wind directions.
The utility model content
In view of this, the purpose of this utility model provides a kind of transmission line bundle conductor that can effectively stop and waves, and can reduce the centrifugal force that conductor galloping produces, and reduces and waves frequency and reduce the amplitude of waving, and can adapt to the bundle conductor anti-dance device of different wind directions.
Bundle conductor anti-dance device described in the utility model comprises conductor spacer, fork and pendulum, and described pendulum is arranged at the anti-dance device lower end by making its device with respect to the conductor spacer side-to-side movement on perpendicular to the in-plane of lead.
Further, the described pendulum that can make is the pipe of sealing two ends with respect to the device of conductor spacer side-to-side movement, and the pendulum that is placed in the pipe is the ball of diameter less than the pipe diameter, and pipe is horizontally set on the anti-dance device lower end and is rigidly attached on the conductor spacer by fork;
Further, described pipe two ends are provided with weight;
Further, the pipe two ends inner face of described sealing two ends is provided with spring;
Further, the anti-icing fluid that liquid level is lower than pipe diameter 3/4 is equipped with in described pipe inside;
Further, the described pendulum that can make is and the hinged fork of conductor spacer that the fork lower end is connected with pendulum with respect to the device of conductor spacer side-to-side movement.
Further, the described pendulum that can make is pulley track and pulley with respect to the device of conductor spacer side-to-side movement, and pulley track is horizontally set on the anti-dance device lower end and is rigidly attached on the conductor spacer, and pulley is connected with pendulum by fork.
The beneficial effects of the utility model are: bundle conductor described in the utility model adopts the structure of pendulum with respect to the conductor spacer side-to-side movement with anti-dance device, make pendulum because inertia and opposite with respect to the lead swaying direction, and offset oscillatory forces and do not produce centrifugal force, can effectively reduce and wave frequency and reduce the amplitude of waving; Because pendulum is arranged on the anti-dance device bottom, therefore can adapt to different wind directions; According to the radical of bundle conductor, conductor spacer can be made different shapes, to adapt to the transmission line more than the binary fission.
