Abstract
The invention discloses a principle of storing energy by tensioning a spring, and relates to a device for increasing a brake separating speed by using tension force of the spring during brake separating. The device can effectively increase the speed during brake separating, so that the arc discharge phenomenon of a knife switch during the brake separating is avoided, and the reliability of a manual brake separating mechanism is greatly improved and the service life of the manual brake separating mechanism is greatly prolonged.
Description
Affiliated technical field
The technology of the present invention is a kind of be stretched principle of storage power of spring of utilizing, and realizes the device of the rapid separating brake of circuit breaker.
The development technical background
Manual brake separating mechanism is an electric power system mode commonly used, it provides the control of opening circuit when the needs manual brake separating, but it is exactly that opening velocity is easy to generate the arcing phenomenon slowly that the brake separating mechanism of rigid connecting type has a shortcoming, this disadvantages affect its operating efficiency and reliability, make contact terminal be easy to generate sintering phenomenon, limited its application and development.Be very important at the novel manual brake separating mechanism of this phenomenon development.
Goal of the invention and content
The technology of the present invention is at the deficiency of existing manual brake separating mechanism, adopted spring to be stretched to the conversion process of energy of reinstatement attitude, speed in the time of improving separating brake effectively, thereby the arcing phenomenon when having overcome separating brake have improved the reliability of manual brake separating mechanism greatly.
The technical scheme that the technology of the present invention adopted is as follows:
It is by one section 3 spring for the manual brake separating spring energy agency, when turning clockwise 1 handle, 6 connecting levers move up and spur the elongation of 3 springs, thereby stored certain energy (because of plug-in strip has certain other structures of self-closing power motionless), energy storage is finished when arriving 2 locating pieces, and continuing to move just is hard the connection again, and driving whole device will move up simultaneously, 7 connecting rods turn clockwise thereby 4 connecting levers turn clockwise drive, and 7 connecting rods link to each other with 5 brake separating mechanisms; Because 5 brake separating mechanisms are in critical condition (because of plug-in strip has certain self-closing power), when separating brake moments 3 spring shrinks rapidly under the energy stored effect, quickened the speed of 4 connecting levers, 7 connecting rods, thereby improved the speed of 5 brake separating mechanisms, avoided the arcing phenomenon, improve the reliability of entire mechanism greatly, avoided the sintering phenomenon of the contact terminal of brake separating mechanism, increased the useful life and the security reliability of contact terminal.

Claims (1)
- The manual brake separating spring energy agency be a kind of utilize spring be stretched can storage power principle, realize the device of the rapid separating brake of circuit breaker, it constitutes is exactly one section spring of adding in connecting rod.Its principle is: when moving the action of handle realization separating brake, this section spring is subjected to stretch and has stored certain energy, and energy storage is finished when arriving the location, and continuation is moved again, and whole device will move simultaneously, thus the brake separating mechanism separating brake; Because the contact terminal of brake separating mechanism is in critical condition, when contact terminal separates moment this section spring under the energy stored effect, quickened the opening velocity of entire mechanism, avoided the arcing phenomenon, improved the reliability of entire mechanism greatly, reduce the sintering phenomenon of contact terminal simultaneously, increased the useful life of contact terminal.
