Abstract
The utility model relates to a high voltage isolator's damping shock -absorbing structure, its characterized in that damping shock -absorbing structure comprises the shock -absorbing rod who supports the base with connecting supporting base four corners department, and between the post insulators and base that damping shock -absorbing structure installed at high voltage isolator, wherein post insulators installs on supporting the base, connects the shock -absorbing rod on supporting the base, and its other end fixed mounting is on high voltage isolator's base. Its characteristics are: utilize the damping of damping shock -absorbing structure, absorb the vibration energy who produces when high voltage isolator closes a floodgate, eliminate or weaken the influence that produces post insulators, make closing operation more steady, improved the high voltage isolator reliability of operation.
Description
Technical field
This utility model relates to the damping shock absorption structure of a kind of high voltage isolator equipment, particularly high voltage isolator.
Background technology
Outdoor high-voltage isolating switch includes double-column horizontal open-type and three post horizontally openable formulas, when closing operation, depends on
Rotate the horizontal cross produced to rotate by support insulator, drive contact thereon and fingertip until making contact, complete contact
Enter the closing operation in fingertip.Especially three post horizontally openable formula high voltage isolators, are by the moving contact in rapid movement
Clash into and be arranged on the static contact seat on insulator top, be blocked spacing after complete to close a floodgate further around self upset 90 °, in the process,
Moving contact clashes into static contact seat can produce the biggest vibration energy, and traditional structure is to be mounted directly support insulator to be fixed on height
On pressure disconnecting switch pedestal, and pedestal itself does not have the vibration energy absorbing collision generation of closing a floodgate, and therefore vibration energy is direct
Act on support insulator, the lateral pull that the binding post on support insulator top produces with external electrical network wiring in addition, make
Support insulator bears the biggest horizontal cross dynamic load, now such as External Force Acting, post insulator in the moment closed a floodgate
Son is easy to rupture, and causes power outage.
Summary of the invention
The purpose of this utility model is to provide the effective damping of a kind of energy, absorb combined floodgate vibration energy, it is ensured that safe and reliable
The damping shock absorption structure of the high voltage isolator run.
Technical solution of the present utility model is: the damping shock absorption structure of a kind of high voltage isolator, it is characterised in that
Damping shock absorption structure is to be made up of the decoupling rod supporting base be connected at support base corner, and damping shock absorption structure is arranged on
Between support insulator and the pedestal of high voltage isolator, wherein support insulator is arranged on support base, is connected to support
Decoupling rod on base, its other end is fixedly mounted on the pedestal of high voltage isolator.
The two ends of decoupling rod are provided with external screw thread, are fixedly connected on support base and pedestal by nut respectively, decoupling rod
Setting height(from bottom) regulated by nut.
Feature of the present utility model is: utilizes damping shock absorption structural damping, absorb generation when high voltage isolator closes a floodgate
Vibration energy, eliminates or weakens the impact producing support insulator, makes closing operation more steady, improves high_voltage isolation and open
Close reliability of operation.The decoupling rod height of damping shock absorption structure can regulate, convenient installation.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model is arranged on high voltage isolator.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the damping shock absorption structure installed on a support insulator of high voltage isolator, and damping shock absorption structure is
It is made up of support base 4 and decoupling rod 5.It is fixedly connected on by bolt assembly 7 bottom the support insulator 3 of high voltage isolator
Support on base 4.At the corner supporting base, it is respectively arranged with two ends wear with externally threaded decoupling rod 5, decoupling rod upper end
Cross support base, and be fixedly connected on support base by upper lower nut 8.Decoupling rod lower end is through the base of high voltage isolator
Seat 6, and be fixedly connected on pedestal with lower nut 9.The setting height(from bottom) of decoupling rod can pass through connected nut 8 or spiral shell
Female 9 are adjusted.When carrying out closing operation, moving contact 1 is moved quickly in static contact seat 2, after being stopped by static contact seat, opens
Beginning to do the rotary movement closed a floodgate around self, upset i.e. completes feed motion to 90 °.In making process, moving contact 1 clashes into static contact seat
The vibration energy produced, passes to, in damping shock absorption structure, make vibration energy be damped, absorb, thus disappear through support insulator
Remove or weaken the impact that support insulator is produced, it is ensured that high voltage isolator safe and stable operation.
Damping shock absorption structure of the present utility model is not limited to above-described embodiment.
