Energy storing device of breaker

Abstract

The invention belongs to the field of control of distribution and transmission equipment, and relates to an energy storing device of a breaker. The energy storing device comprises a mounting frame, wherein the mounting frame comprises a first side plate and a second side plate; a motor is arranged at the lower end of the mounting frame; a small gear press-fitting assembled piece is connected at the output end of the motor; the small gear press-fitting assembled piece is mounted on an outer side panel of the second side plate; a gear shaft is arranged between the first side plate and the second side plate; one end of the gear shaft is matched and connected with the small gear assembled piece, and the other end of the gear shaft is matched and connected with a big gear. According to the energy storing device of the breaker, preparation before switching in is realized by directly adopting the energy storing device on a high-voltage breaker or a medium-voltage breaker, therefore, the energy storage is realized fast, the switching in time is reduced; the arc phenomenon caused by the electric arc generated from contact combination is avoided; and the energy storing device of the breaker is simple and reliable, convenient to use, low in manufacturing cost and easy to maintain.

Description

technical field [0001] The invention belongs to the field of power transmission and distribution equipment control, and relates to an energy storage device for a circuit breaker. Background technique [0002] With the country's continuous investment in infrastructure construction, the annual power demand has also increased geometrically, the contradiction of power supply has become more prominent year by year, and the problem of tight power demand has become increasingly prominent. At the same time, the demand for electrical equipment has also undergone major changes, especially high and medium voltage. The safety and reliability of power transmission and distribution equipment directly affects the operation quality of the line. Therefore, it is particularly urgent to ensure the safe and stable operation of high and medium voltage power transmission and distribution equipment and avoid failures. [0003] At present, electric closing and opening and manual closing and opening...

AI Technical Summary

Problems solved by technology

[0003] At present, electric closing and opening and manual closing and opening are used on high and medium voltage circuit breakers. It is easy to operate without professional training personnel, which will cause hidden dangers to power transmission and distribution equipment, especially when the equipment needs maintenance. There are potential personal safety hazards. The handle on the low-voltage circuit breaker uses a padlock to control the closing and opening of the switch. However, due to structural limitations on the medium and high-voltage circuit breakers, the above functions cannot be realized. Therefore, misoperation is prone to occur during equipment maintenance and directly affects personal safety.

At present, all medium and high voltage circuit breakers do not have a special function to prevent misoperation of the circuit breaker during maintenance. They can only be warned by listing, and there is no guarantee that the brand will not be lost.
