Description
- The present technology relates to a device that provides damping and support to electrical equipments and more specifically relates to a device that provides damping and support to upstanding high voltage components to protect them from vibrations, for example, seismic vibrations.
- Large upstanding electrical equipments require support and damping means for reducing vibrations caused due to various reasons, for example, seismic vibrations, earthquakes, vibrations during operation of the equipment and other such shaking movements. Without sufficient damping and support, excessive motion of the vertical upstanding equipment, relative to the main base frame, could occur when the frequency of the ground motion is such as to cause amplification of the vertical upstanding equipment motion. Damping is one of many different methods that have been proposed for allowing a structure to achieve optimal performance when it is subjected to seismic, wind storm, blast or other types of transient shock and vibration like disturbances.
- Devices for control of mechanical vibrations by use of dampers are known in the literature.
- Prior art U.S. Pat. No. 3,973,078 is of interest with respect to this patent application. It discloses an energy absorbing device, such as a liquid filled vibration damper assembly, for preventing excessive relative motion between the lower supporting plate of the upstanding column, supporting electrical equipment, and the adjacent lower-disposed main supporting framework structure. Preferably, the energy absorbing device is a liquid filled dash-pot assembly which is utilized at one or more locations extending between the lower supporting plate member of each upstanding column structure and the lower disposed main supporting framework.
- Prior art U.S. Pat. No. 3,911,199 is also of interest with respect to this patent application. It discloses a seismic motion-damper for upstanding electrical equipment comprising an inertia element disposed within a container containing a fluid liquid attached to an upper portion of upstanding electrical equipment. Said damper is tuned so as, by utilizing sympathetic vibrations, tends to cancel out seismic vibrations, which otherwise could damage the electrical equipment.
- There still exists a need for a simpler, more robust and affordable damping solution for electrical equipment to protect it from vibrations.
- It is an object of the invention to provide for a robust yet simple damping and support structure for electrical equipment.
- The object of the invention is achieved by a device for supporting an equipment by implementation of viscous dampers together with wire rope dampers arrangement with optimized positioning. The device comprises a base plate, a foundation plate, a set of viscous dampers connecting the base plate to the foundation plate and a set of wire rope dampers, wherein the set of wire rope dampers bear the base plate and connects the base plate to the foundation plate.
- Viscous dampers operate on the principle of fluid flow through orifices. Viscous damping is caused by such energy losses as occur in liquid lubrication between moving parts or in a fluid forced through an orifice or a small opening by a piston. The damper typically contains a piston inside a cylinder filled with viscous fluid. Small ports or holes allow fluid to move back and forth in the cylinder, but the bulk of the fluid resists any movement of the piston.
- Wire rope dampers are a kind of dampers made of coiled wire ropes that possess elastic and energy dissipation characteristics and are flexible enough to absorb the energy that causes vibrations to the equipment.
- The viscous dampers supplement the damping from the wire rope dampers. Viscous dampers alone are not able to support the equipment. They only provide additional damping. The use of these two kinds of dampers together along with their optimized configuration (position of the wire ropes, number of viscous dampers) provide an enhanced damping solution giving more than twice better results than if the wire rope dampers were used alone. Moreover, it also ensures cost savings through the adaptability of the device to different equipment characteristics. Therefore, arranging viscous dampers together with the wire rope dampers helps to deal with increased damping requirements by using a cost-optimized arrangement.
- The arrangement of the device should be optimized based on the characteristics of the equipment. Parameters for optimization based on current equipment needs are, for example, type of wire ropes or wire rope dampers, type of viscous dampers, the number of viscous dampers per support adaptor, for instance, at least one and up to five, the angle of viscous dampers or the position of the wire rope dampers along the axis of the center towards the support adapters and extending to the viscous dampers.
- The arrangement should be optimized to achieve the required damping as per equipment's needs in relation to minimizing the amount of viscous dampers and in addition to minimizing the costs of the device.
- In one embodiment of the invention the device further comprises a set of support adapters for connecting the viscous dampers and the wire rope dampers to the foundation plate. The support adapters offer a firm grip between the dampers and the foundation plate. It prevents the dampers from slipping on the foundation plate due to vibrations.
- In another embodiment of the device at least one viscous damper and at least one wire rope damper are connected to the same support adapter. This provides the most optimized arrangement of dampers and support adapters by reducing the number of support adapters needed for the device. This leads to cost optimization for the device.
- The viscous dampers connect the base plate to the support adapter. The support adaptor hosts both viscous dampers and wire rope dampers and further connects them to the foundation plate through bolts. The foundation type is not within the scope of this application.
- In an alternative embodiment of the device, the device further comprises a set of shake table adapters, wherein the shake table adapters connect the support adapters to a shake table. Shake tables are used for testing the device for its ability to withstand vibrations. Shake tables induce vibrations into the device. Shake table adapters in the device provides an attaching means for attaching the support adapters to a shake table. This feature makes the device connectable to a shake table for testing purposes.
- In a preferred embodiment of the device the base plate is orthogonally shaped. An orthogonal base plate provides a most suitable surface for attaching the dampers to the flat edges. Moreover using an orthogonal shape for the base plate ensures the most optimum arrangement of dampers around and below the base plate that can provide the maximum support and resistance against vibrations.
- In another embodiment the device further comprises a set of angular fixtures connecting the foundation plate to the base plate by means of the viscous dampers. The angular fixtures have two surfaces at right angles to each other. One surface is affixed on to the surface of the base plate, and the other surface, which is perpendicular to the first surface, provides a flat fixing surface for one end of each of the viscous dampers. The other ends of the viscous dampers are attached to the support adapter. The angular fixture helps the dampers grasp the base plate firmly. It also makes it possible to align the viscous dampers at a desired angle to the foundation plate.
- In an embodiment, the support adapters have a hole pattern. The hole pattern in the support adaptors and the angular fixtures is arranged in a way that any number (from 1 up to 5) of viscous dampers shall be able to be adapted symmetrically to the center of the adaptors. Hence, the same elements can be used for different applications and the redesign of these parts is not essential which further decreases costs.
- In a preferred embodiment the set of viscous dampers constitutes up to five viscous dampers per support plate. Having too many viscous dampers would increase the cost of the device. Five viscous dampers per support adapter would provide the necessary and sufficient support without increasing the cost of the device exponentially.
- In an embodiment of the device, the equipment is one of a double and single chamber life tank high voltage AC circuit breaker, HVDC high speed switches, high voltage arresters, high voltage disconnectors with a T-type steel support, HVDC voltage dividers, high voltage single stand bus support, high voltage earthing switch or a high voltage pantograph. The equipment can also be any other equipment that needs protection and damping against vibrations.
- In yet another embodiment the wire rope damper is connected to the base plate at a base plate connection point and the base plate comprises a centre and an outer edge, and wherein the distance between the base plate connection point and the centre of the base plate is lesser than the distance between the base plate connection point and the outer edge of the base plate. Positioning of the wire ropes towards the center of the base plate provides the most optimum support and the damping action is more pronounced.
- Positioning of the wire rope damper system in the manner mentioned above allows for higher displacements through rocking motions up to maximum limits of the viscous dampers and as a result allows for maximum additional damping from the viscous dampers.
- In an exemplary device the equipment is a circuit breaker, Siemens 3AP3FI, the viscous dampers that are used are Enidine LD2418810E and the wire rope dampers are Enidine WR4020008 equivalent.
- An exemplary device has a height of 6 m and weight of 5 tons. It provides a 30% damping action to a rocking movement.
- In a preferred embodiment of the device, the viscous dampers are arranged at an angle of 77 degrees to the foundation plate. Optimized positioning and damper mechanical characteristics can be studied and developed through non-linear time history analysis and calibrated to a reference shake table test in order to arrive at the optimum device characteristics. Angles other than 77 degrees is also conceivable based on the desired damping characteristics needed.
- The above-mentioned and other features of the invention will now be addressed with reference to the accompanying drawings of the present invention. The illustrated embodiments are intended to illustrate, but not limit the invention. The drawings contain the following figures, in which like numbers refer to like parts, throughout the description and drawing.
