Manual energy storing device of permanent magnetic circuit breaker

Abstract

The invention discloses a manual energy storing device of a permanent magnetic circuit breaker, which relates to a permanent magnetic circuit breaker and comprises a transmission mechanism of a permanent magnetic circuit breaker, wherein the permanent magnetic circuit breaker drives a rotating plate to complete the switch-on and switch-off actions via a bearing of the transmission mechanism, the transmission mechanism is fixed by a left side plate and a right side plate, a transmission shaft is arranged between the left side plate and the right side plate, the outer part of the transmission shaft is sleeved with a transmission shaft sleeve and a transmission shaft gear, a motor is also arranged between the left side plate and the right side plate, the motor is emerged in a cavity between the left side plate and the right side plate, and protruded power lines in the motor are connected with power supply contact points of the transmission mechanism to charge an energy storing capacitor.The tail end of the motor is also provided with a rotating handle which is externally connected with a manual rocker arm, reverse charging energy storage is carried out to the motor via the rotation of the manual rocker arm, the charged motor provides power for the transmission mechanism, and the transmission shaft in the transmission mechanism rotates to drive the rotating plate to complete the switch-on and switch-off actions. The invention has the advantages that manual operation and electric operation are combined well, the manual operation equipment and permanent magnetic circuit breakerare arranged together without additional devices for providing power, and the use is convenient, safe and quick.

Description

technical field [0001] The invention relates to a permanent magnet circuit breaker, in particular to an energy storage device for manual closing and opening of a permanent magnet circuit breaker in a power system. Background technique [0002] Permanent magnet circuit breakers are mainly used in power systems as control and protection switches for high-voltage electrical equipment. It is required to be able to perform electric closing and opening operations, as well as manual closing and opening operations. At present, the closing and opening of the electric operation has become more and more mature, and the manual operation is still in the discussion stage. Although there have been some permanent magnet circuit breakers about manual operation, there will always be some problems in the use process. One is to realize manual operation. Closing and manual opening both require their own supporting parts, and the operating parts are complicated and there are many parts; second, t...

Problems solved by technology

However, the disadvantage of this method is that the manual operation is completely separated from the electric operation, and complementary interference, so that it takes more effort to complete the closing and opening operations for manual operation.

[0004] Based on this, a method combining manual operation and electric operation has appeared in the market at present, which is very convenient to operate, but the method of operation is to use an external charger to charge the charger through the rotation of the manual handle. , and then connect the contacts on the charger with the permanent magnet circuit breaker to achieve the control device to control the closing and opening actions of the permanent magnet circuit breaker. Although this method solves the problem of using electric-operated permanent magnet The circuit breaker cannot complete the closing and opening operations without power supply, but the external equipment always has a certain volume and weight, and it needs to be carried by the staff, which is also not very convenient.
