Abstract
The invention discloses an operating mechanism of an electricity leakage reclosure circuit breaker, relating to the technical field of circuit breakers and overcoming the defects that the radial force of a motor rotating shaft of the existing electricity leakage reclosure circuit breaker is unbalanced to cause the damage of a motor. The operating mechanism comprises a handle and a motor which are arranged on a body, the handle is connected with the motor by a connecting rod, a ratchet wheel is arranged on the motor, the connecting rod is connected with a pawl through a crank, the ratchet wheel and the pawl are meshed, an elastic sheet is arranged between the connecting rod and the crank, and a manual push rod is arranged on the connecting rod; when the motor works, a multi-pawl structure can ensure the balance of radial force of the motor rotating shaft, thus avoiding the damage to the motor due to radial force generated in rotation of a crank connecting rod mechanism; when the motor is not needed to work, the ratchet wheel does not work when manual operation is adopted, the pawls and the ratchet wheel can be separated by rotating a shaft on the crank, so that the crank connecting rod mechanism can successfully run reliably towards one way.
Description
Technical field
The present invention relates to breaker technical field, particularly a kind of operating mechanism of the reclosing circuit breaker that leaks electricity.
Background technology
The operating mechanism of electric leakage reclosing circuit breaker is when motor operation, and the motor rotary shaft radial load is uneven, and when the toggle of motor rotated, the radial load that produces was damaged motor.
Summary of the invention
The objective of the invention is: provide a kind of operating mechanism of the reclosing circuit breaker that leaks electricity, to overcome the existing defective that adopts the spring life low technical.
According to above-mentioned purpose, the technical solution adopted in the present invention is: a kind of operating mechanism of the reclosing circuit breaker that leaks electricity, comprise the handle and the motor that are installed on the body, handle is connected with motor by connecting rod, it is characterized in that: described motor is provided with ratchet, described connecting rod is connected with ratchet by crank, and described ratchet is meshed with described ratchet.
Be provided with shell fragment between described connecting rod and the crank.
Described connecting rod is provided with hand push rod.
The rotating shaft of passing through of described motor is connected with ratchet, and described rotating shaft is provided with the oval plane, also is provided with the oval plane of matching with it on the described ratchet.
Be connected by circular hole between described crank and the ratchet.
Described ratchet is provided with more than 1 or 1.
Compared with prior art, advantage of the present invention and beneficial effect are:
1, the present invention is owing to being equipped with ratchet on the crank connecting link, and when motor operation, many pawl structures can guarantee radially equilibrium of forces of motor rotary shaft, avoids motor because of the radial load that toggle produces when rotating and damages motor;
2, the rotating shaft of the ratchet of structure of the present invention and motor is rotated simultaneously, and the crank of toggle is radially for rotating with the rotating shaft of motor, when not needing motor operation, and when adopting manual operation, ratchet does not rotate, this moment the axle on the rotating crank, ratchet can separate with ratchet, so that toggle can be smoothly towards a unidirectional reliable running.
3, more simple and reliable than existing from part complexity and processing technology.
