Description
Technical field
The utility model relates to a kind of DC filter capacitors device, particularly a kind of ± 800kV ultra high voltage suspension type DC filter capacitors device.
Background technology
Traditional DC filter capacitors the complete sets of equipment electric pressure is ± 500kV, and apparatus structure is upright console mode, and is highly relatively low, and this upright console mode device can satisfy antidetonation and electric property substantially to the low DC transmission engineering of electric pressure.When the electric pressure of DC transmission engineering reach ± during 800kV, very big variation has occured in the height of extra-high voltage direct-current filter capacitor device and weight, the shock resistance of traditional vertical structure device can not meet the demands, and whole stability is also relatively relatively poor, has larger potential safety hazard.
The utility model content
Technical problem to be solved in the utility model provides a kind of ± 800kV ultra high voltage suspension type DC filter capacitors device to satisfy shock resistance, solves potential safety hazard.
To achieve these goals, the utility model adopts following technical scheme:
A kind of ± 800kV ultra high voltage suspension type DC filter capacitors device, comprise portal frame, suspended compound insulator, capacitor body, adjustable screw button and pulling force sensor, described capacitor body couples together by suspended compound insulator and is suspended on the portal frame, the capacitor body of the bottom is connected with the adjustable screw button, the lower end of this adjustable screw button is connected with pulling force sensor, with the size of measuring and adjusting pulling force.
As preferred version of the present utility model, described ± 800kV ultra high voltage suspension type DC filter capacitors device further includes grading ring, and this grading ring is installed in around the capacitor body that is positioned at high-pressure side, so that Electric Field Distribution is even;
As preferred version of the present utility model, the protected mode of described ± 800kV ultra high voltage suspension type DC filter capacitors device is the poor unsymmetrical current protection of bridge, the capacitor cell that namely damages by the photoelectric current inductor reflection, described photoelectric current inductor is installed in the middle part on the H molded line road of DC filtering apparatus;
Compared with prior art, the utility model ± 800kV ultra high voltage suspension type DC filter capacitors device has the following advantages at least: the utility model adopts overhung construction, and anti-seismic performance is good, reaches more than 8 degree; Grading ring has been installed, has been made Electric Field Distribution even; The protected mode of device is the protection of the poor unsymmetrical current of bridge, can reflect timely and effectively the capacitor cell of damage by photoelectric current inductor, in time changes the expansion of Accident prevention.Height and the pretightning force of device are buckled adjusting by enclosed auger, and pretightning force can read by the pulling force display.Rational in infrastructure, electric property is stable.

Fig. 2 is the overall structure schematic diagram of the utility model device.
Embodiment
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is done further and to elaborate:
See also Figure 1 and Figure 2, the utility model device comprises suspended compound insulator 1, grading ring 2, photoelectric current inductor 3, capacitor body 4, adjustable screw button 5 and the pulling force sensor 6 of portal frame, clavate.Described capacitor body 4 couples together by suspended compound insulator 1 and is suspended on the portal frame, totally 30 layers of capacitor bodies, the capacitor body of the bottom is connected with adjustable screw button 5 and regulates pulling force, the lower end of this adjustable screw button 5 is connected with pulling force sensor 6, with the size of measuring and adjusting pulling force.The resistance to overturning of the utility model device is good, and shock resistance is good.
The utility model is at the suspended compound insulator 1 suspention capacitor body of portal frame by clavate, in addition, the utility model device has been installed grading ring at high-pressure side, and described grading ring is installed in around the capacitor body of high-pressure side from top to down, makes Electric Field Distribution even; The protected mode of filter apparatus is the poor unsymmetrical current protection of bridge, namely by reflecting timely and effectively the capacitor cell of damage, in time changes, and the expansion of Accident prevention, described photoelectric current inductor is installed in the middle part on the H molded line road of device.The height of device and pretightning force are regulated by the turn buckle of enclosed, and pretightning force can read by the pulling force display.Rational in infrastructure, electric property is stable.
The above only is a kind of execution mode of the present utility model, it or not whole or unique execution mode, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
