Description
The utility model relates to a kind of high pressure porcelain electrical equipment that is used to support, the vertical lead alloy damper of earthquake disaster mitigation.
High pressure porcelain electrical equipment is because the requirement of insulation all adopts ceramic material to make, because the low brittle material that belongs to again of intensity, therefore normal badly damaged fractureing under the violent earthquake effect caused power outage, and loss is serious.In order to improve the ability that high pressure porcelain electrical equipment is resisted earthquake, the unit that China has once developed the rubber absorbers " earthquake research of oil-minimum breaker and shock absorption system thereof, the .1981 of earthquake research institute of First Machinery Industry Department ", shortcoming is that equipment displacement when operation and earthquake is bigger, damping performance reduces during low temperature, and have a problem such as aging replacings of vibration damper, and also adopt rubber absorbers below French some electrical equipment, also dislike excessive through the testing installation displacement.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provide a kind of lead alloy main part, its top and the bottom diameter is thick (having the rectangle bead), intermediate portion is more carefully located the absorbing vibration energy, vibration equipment is little when operation, can not wear out plasticity energy-dissipating property brilliance, the vibration damper that is assembled into frame head plate, base plate.
This vertical lead alloy damper is made up of lead alloy main part, support plate, top board, base plate, side framework, is used to support high pressure porcelain electric equipment.Rock displacement for reducing it, four lead alloy main parts are contained in the side inside of frame with lead-antimony alloy material forms, and main part body upper end portion is enclosed within four holes of framework upper plate, exceed the top board face a little, rock to stop it.Square floor respectively is equipped with in two pipe support upper-end surfaces, four lead alloy main parts that damping is used are housed on each square floor, and thin in the middle of main part body two end part are thick, the stage casing is made for circular in the bottom, the rectangular shape in both sides, its centre of axially overlooking below the top is circle, and both sides are rectangular, are circular above the top, 4 hole sliding fits with top board, bottom thickness is about a times of face thickness under the top, and lead alloy main part body is the both ends of the surface center up and down, respectively studs with the screw rod of end band screw thread.Square floor is circular elongated slot near four jiaos of places in the middle of having, orthogonal center line of the center line of this groove and base plate right angle bisector coincide, to determine totally four of its positions; Above the every pipe support upper end square top board is housed, size is consistent with base plate, and four jiaos of relevant positions have four of open-works, the centres of the circular elongated slot of its center and base plate.
Adorn support plate on the square floor, both centers are with holes, and screw rod is passed through.Be welded with 8 gussets below the base plate and strengthen supporting force, near four jiaos of places the middle circular slotted hole that is is arranged on the base plate, to the centre of lead alloy main part is that the rectangular partial shape in circular both sides is similar, but slotted eye is big 1 millimeter than the corresponding fit dimension of the similar part of main part body, be convenient to main part and pass through, by after, 90 ° of main part body revolutions, it is abutted against on the support plate on the base plate, with nut that screw rod is fastening again.Top board is welded on the side framework, and framework is welded on the base plate, and four of open-works are arranged above the top board, the circular upper end portion of main part body is by open-work and exceed above the top board 10 millimeters, 4 holes, relevant position of plant bottom case plate are sleeved on the screw mandrel of lead alloy main part top, and are fastening with nut.
Vibration damper of the present utility model carries out too much inferior actual loading test on large vibration table, input surpasses the resonance bat ripple that 9 U.S. of spending earthquakes like Ademilson sieve (Elcentro) ripple in the wrong and are equivalent to 10 degree earthquakes, Plant in good condition is harmless, after vibrational energy surpasses certain value, the vibrational energy that increases, to dissipate and do not pass to equipment by vibration damper, thereby guarantee the safety of equipment.As not being subjected to the restriction of vibrating table output energy etc., this vibration damper also can bear bigger vibration test.
Advantageous effect and purposes:
1. present rubber absorbers operation and when being shaken amplitude bigger, damping performance reduces during low temperature, and have aging must replacing etc. problem.This vibration damper directly is contained in above the pipe support, lead alloy main part upper end and framework upper hole sliding fit, and rigidity is connected as a single entity, and reduces and rocks displacement amount, is not subjected to low temperature effect, there is no problems such as aging replacing.
2. when meeting with violent earthquake, vibration damper mainly bears tension and compression load repeatedly, and the distortion power consumption concentrates on the thin part in lead alloy main part middle part, can absorb most of seismic energy, significantly reduce the energy of passing to electrical equipment, thereby improved the shock resistance of high pressure porcelain electrical equipment.
The antiseismic ability of this vibration damper is strong, makes simply, and maintenance work is few, and is cheap, is suitable as the damping device of each power station high pressure porcelain electrical equipment.
