Chinese patent document CN101599389B discloses a double-acting self-energy thermal expansion type high-voltage sulfur hexafluoride circuit breaker interrupter with this function, which includes a moving contact mechanism and a static contact installed directly above the moving contact mechanism The head mechanism, the static contact mechanism includes the static main contact, the static arc contact seat and the static arc contact, the moving contact mechanism includes the arc extinguishing nozzle, the moving main contact and the moving arc contact, the moving main contact and the moving arc The contacts correspond to the static main contact and the static arc contact respectively. The arc extinguishing nozzle includes the main nozzle and the inner nozzle coaxially arranged inside and outside, and the moving arc contact is located inside the inner nozzle; The connected push-pull rod drives the shift fork to rotate, and then through the cooperation between the pin shaft connecting the static arc contact and the shift fork and the horizontal pin hole, the static arc contact is driven to move up and down along the vertical guide rail to realize the moving contact and static arc contact. The reverse movement of this kind of double-action transmission device in the form of a shift fork and a guide rail is not only complex in structure and takes up a large space, but also requires high precision in processing and assembly. The production process is relatively complicated, and processing and assembly are difficult. In addition, the transmission ratio of the fork transmission is not easy to control, making it difficult to control the action time and movement distance of the static arc contact at a constant value, and it is prone to lagging of the static arc contact , the stability of its action time is poor

Abstract

The invention relates to a high voltage sulfur hexafluoride breaker and a double acting transmission device of the high voltage sulfur hexafluoride breaker. The high voltage sulfur hexafluoride breaker comprises a silent arc contact, a stationary contact assembly and a moving contact assembly. The double acting transmission device is arranged between the stationary contact assembly and the moving contact assembly. The moving contact assembly drives the silent arc contact to move reversely through the double acting transmission device. The double acting transmission device comprises a driving rack and a silent arc contact rack which are parallel and extend along a moving direction of the moving contact assembly. A gear in engaged transmission with the two racks simultaneously is arranged between the driving rack and the silent arc contact rack. The position of a rotary shaft of the gear is fixedly arranged. The driving rack is fixedly connected onto the moving contact assembly and reciprocates linearly with the moving contact assembly. The driving rack drives the silent arc contact rack to move reversely through the gear, and the silent arc contact rack is fixedly connected onto the silent arc contact and drives the silent arc contact to reciprocate linearly. According to the high voltage sulfur hexafluoride breaker and the double acting transmission device of the high voltage sulfur hexafluoride breaker provided by the invention, the structure is simple, the cost is low, and the requirement of the breaker on the opening speed is met better.

Description

technical field [0001] The invention belongs to the technical field of high-voltage sulfur hexafluoride circuit breakers, and in particular relates to a double-acting high-voltage sulfur hexafluoride circuit breaker and a double-acting transmission device thereof. Background technique [0002] With the continuous and in-depth research on the structure of the high-voltage sulfur hexafluoride circuit breaker arc extinguishing chamber, people have invented a self-energy thermal expansion high-voltage sulfur hexafluoride circuit breaker on the basis of the single-pressure compressed gas type sulfur hexafluoride circuit breaker arc extinguishing chamber The arc extinguishing chamber of the arc breaker uses the energy of the arc itself to greatly reduce the operating work, which is a big step forward in technology. Even so, due to the current single-pressure and self-energy circuit breaker interrupters, the opening and closing of the dynamic and static contacts are fixed by the st...
