Technical field
The present invention relates to power engineering equipment technical field, specially a kind of electrical system seismic support frame.
Background technology
Electric power facility in the transformer station of earthquake territory not only needs good technology arrangement, and needs with good antidetonation
Damping performance, and the shock absorption system in China's electric power facility for electrical equipment applies less at present, and existing damping device
The requirement of electrical equipment when can not meet practice of construction, it is impossible to ensure that whole power system can be with safer operation.
Such as a kind of damping device for electrical equipment of (China) application number 201010524100.6, it can improve electrically
The anti-seismic performance of equipment, can improve the margin of safety of electric power facility again, no matter in normal state or in earthquake can be more preferable
Ground ensures the safe operation of electrical equipment.Although the damping device can reach electrical equipment by lip block, damper
The effect of antidetonation, but damper is made up of multiple construction machines, certainly will there is regulation inconvenience, once run into cooperation mistake
Maintenance workload will be increased.
And a kind of rigidity of (China) application number 201110431184.3 and damping adjustable type extra-high voltage electrical equipment shock insulation
Bearing, makes standardization, and connected mode is simple, can according to by the difference of the structure of shock insulation or equipment adjust its horizontal rigidity and
Damping, it is possible to play good damping effect.The shock isolating pedestal by cohering between steel plate tooth and rubber unit or rub into
Row transmission, although so can adjust and control rigidity and the damping of bearing according to actual conditions, plays the effect of earthquake isolation,
But cohering between steel plate tooth and rubber unit or frictional damping once diminish, it, which enough bears certain moment of flexure effect, to cut
Weak, damping becomes big to be made to be difficult to occur relative slide between plate tooth and rubber unit again, it is impossible to reach good damping effect.
The content of the invention
It is an object of the invention to provide a kind of electrical system seismic support frame, to solve what is proposed in above-mentioned background technology
Problem.The electrical system seismic support frame has simple structure, easy to maintenance, plays the effect of earthquake isolation, while also making

The direction of axis line of frame or lower carriage is obliquely installed, and the axis parallel of the lamellar body II and upper bracket or lower carriage is set.
It is preferred that, it is described it is raised be elastic bumps, and raised radius successively decreases successively from top to bottom.
Compared with prior art, the beneficial effects of the invention are as follows：Upper bracket plays holding electrical equipment, and lower carriage rises solid
It is set for using；When electrical equipment normal operating condition and wind load or smaller shake effect under, the bear block of elastic buffer cushion block
The beryllium copper shell fragment in upper bracket, lower carriage, buffering locking device can be born by projection by upper bracket, lower carriage card master, held
Carry on a shoulder pole electrical equipment load；When suffering from violent earthquake effect, shear stress, elastic buffering pad are produced between upper bracket, lower carriage
Block plays its support, effect of antidetonation：Relative motion occurs between one side upper bracket, lower carriage, bear block by normal stress,
So that bracer is forced into the hollow intracavitary of buffering locking device, another aspect bracer makes beryllium copper shell fragment upspring, raised and upper bracket,
Contact area gradually increases between lower carriage, and frictional damping becomes big, the effect of earthquake isolation is played, while also making this seismic support
Frame has preferable bending resistance.
This seismic support frame simple structure, it is easy to maintenance, can according to earthquake intensity between upper bracket, lower carriage normal direction
The frictional damping that stress regulation electrical equipment load is produced, plays the effect of earthquake isolation.
