The present invention relates to an automatic lever turning apparatus for an earth leakage breaker having an improved structure, and more particularly, to an improved automatic lever turning apparatus for automatically returning an earth leakage breaker, The present invention relates to an automatic lever turning apparatus for an earth leakage breaker.

Causes of electric leakage include lightning, damage due to external force, and invasion of moisture. Electric leakage may occur due to electric leakage, electric shock or electric fire. In this way, the device for preventing a safety accident by detecting an overcurrent and a leakage current due to a short circuit is cut off.

In recent years, when the cause of a short circuit is canceled, an earth leakage circuit breaker is used in which a lever is automatically raised even if a person does not artificially return the circuit breaker. That is, when the electric leakage is solved after the electric power is cut off due to the occurrence of the electric leakage, the motor is automatically driven to rotate the lever to the off position, and then the electric motor is automatically returned to the on position.

Korean Patent No. 10-1072692 discloses an operation lever drive device for an automatic reclosing circuit breaker. The operating lever driving device includes a driving gear 502 and a sun gear 503 rotated by a motor 515, a planetary gear 504 arranged on a line concentric with the central axis of the sun gear 503, A ring gear 505 which is rotated by engaging with the outer periphery of the planetary gear 504 and has a projection 506 formed on one side of the outer periphery of the planetary gear 504; A pin 507 provided on one surface of the rotating drum 509 for rotating the operating lever 303 and a protrusion 506 of the ring gear 505 are in contact with both ends of the rotating drum 509 And a stopper 510 to be resiliently supported by a spring 511 for allowing the light to pass therethrough.

The worm 516, the worm gear 517, the drive gear 502, the sun gear 503, the planetary gear 504 and the ring gear 505 are driven by the motor 515 in the above- 509 are rotated so that the operation lever 303 is driven. Here, since the initial driving force of the motor 515 is weak, the motor 515 may not operate properly. Particularly, when the motor 515 freezes in winter or a foreign object is stuck in the motor 515 due to long use, a person must operate the operation lever 303 individually.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an automatic lever turning apparatus (hereinafter referred to as an automatic lever turning apparatus) of an earth leakage breaker having an improved structure according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of an automatic lever pivoting device according to an embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating a configuration of an automatic lever pivoting device according to an embodiment of the present invention, and FIGS. 1 is a view showing a structure of a second spur gear included in an automatic lever turning apparatus according to an embodiment of the present invention;

Referring to FIG. 1, the automatic lever pivoting device is equipped with an operation lever 300 which can be manually turned on and off, and the drive units 100 and 500, which can automatically drive the operation lever 300, 330, 340, and 350, respectively.

Referring to FIG. 2, the automatic lever turning apparatus of the present invention includes a first driving part 100, a second driving part 500, case parts 330, 340 and 350, an operation lever 300, and an auxiliary lever 310.

The first driving unit 100 is installed between the first case 350 and the intermediate case 340 and includes a motor 110, a first spur gear 120, a second spur gear 130, a worm 150, And a worm gear 170.

The motor 110 is driven by a microprocessor (not shown) incorporated in the earth leakage breaker when a short circuit occurs. A first spur gear 120 is fixedly mounted on a driving shaft of the motor 110 and rotates as the motor 110 is driven.

The second spur gear 130 rotates in conjunction with the first spur gear 120 and rotates together with the worm 150 extending from the center shaft provided with the second spur gear 130. Here, the radius of the first spur gear 120 is smaller than the radius of the second spur gear 130, so that the rotation speed of the second spur gear 130 is slower than the rotation speed of the first spur gear 120.

3 and 4, the second spur gear 130 is rotatably installed between the E-shaped retaining ring 159 and the linear key 157 at one side of the center shaft 155. That is, when the straight key 157 is mounted on the central shaft 155 and the E-shaped retaining ring 159 is fitted in the groove 156 of the central shaft 155, the second spur gear 130 is engaged with the central shaft 155 And is rotatably installed on one side. The worm 150 is extended to the center shaft 155 provided with the second spur gear 130 so that the worm 150 rotates when the second spur gear 130 rotates.

A pair of rotary rings 151 are installed on both sides of the worm 150 and the support springs 351 of the first case 350 and the support springs (not shown) of the second case 340 are fixed to the second spur gears 130 And the worm 150 are supported. The support case of the second case 340 is formed in the same shape as the support case 351 of the first case 350 so that when the first case 350 and the second case 340 are coupled, Is fixedly installed between a support base 351 of the first case 350 and a support base of the second case 340.

The second spur gear 130 has a protrusion 135 formed on a surface thereof which is in contact with the protrusion 135. The protrusion 135 is engaged with the first spur gear 120, The worm 150 also rotates together. The worm gear 170 rotates in engagement with the worm 150, and a large reduction ratio is obtained. Since only the second spur gear 130 rotates for a predetermined period at the beginning of the driving of the motor 110, the second spur gear 130 can be easily rotated even when the initial rotational force of the motor 110 is small.

The second drive unit 500 is installed between the intermediate case 340 and the second case 330 and includes a reduction gear 501, a drive gear 502, a sun gear 503, a planetary gear 504, 505, a rotating drum 509, a stopper 510, a spring 511, a fixing pin 512, a magnet 513, a release lever 514, and a sensor 515.

At least one reduction gear 501 is installed and coupled to the worm gear 170, and the reduction gear 501 rotates the driving gear 502. A sun gear 503 is provided on the central axis of the drive gear 502 and a planetary gear 504 having a central axis concentric with the sun gear 503 is provided.

A ring gear 505 provided with a projection 506 that rotates in accordance with the rotation of the planetary gear 504 is provided on the outer periphery of the planetary gear 504 and the center shaft is fixed to one surface of the planetary gear 504, There is provided a rotating drum 509 provided with a pin 507 which rotates in a semicircular slot 331. [ Further, a stopper 510 is provided, in which the projection 506 of the ring gear 505 is engaged and the position of the spring 511 is changed by the elastic force.

The sun gear 503 in the center of the driving gear 502 is rotated and the planetary gear 504 fixed to the rotating drum 509 by the rotation of the sun gear 503 is rotated, The ring gear 505 engaged with the ring gear 505 rotates. When the protrusion 506 of the ring gear 505 is caught by the stopper 510, the ring gear 505 is in a non-rotatable state.

In this state, the sun gear 503, the planetary gear 504, and the ring gear 505 can not move together, and the planetary gear 504 revolves as the drive gear 502 rotates. The pin 507 of the rotating drum 509 is rotated in the semicircular hole 331 and moves in the slot 315 of the auxiliary lever 310 to rotate the auxiliary lever 310 So that the operation lever 300, which is formed integrally therewith, rotates.

5 to 8 are views for explaining the operation of the operation lever included in the automatic lever turning apparatus according to an embodiment of the present invention.

5, when the ring gear 505 rotating in the counterclockwise direction rotates clockwise, the stopper 510 is changed to the position shown in FIG. 6 by the elasticity of the spring 511, The ring gear 505 rotates clockwise. When the projection 506 is caught by the stopper 510, the ring gear 505 no longer rotates, and the rotating drum 509 rotates in the counterclockwise direction in accordance with the rotation of the driving gear 502.

As a result, the pin 507 of the rotating drum 509 rotates counterclockwise in the semicircular slot 331, and moves in the slot 315 of the auxiliary lever 310 as shown in FIG. Accordingly, the operation lever 300 is moved from the ON position to the OFF position while the auxiliary lever 310 is moved in the counterclockwise direction.

Conversely, when the ring gear 505 rotates counterclockwise and the protrusion 506 is caught by the stopper 510, the rotating drum 509 rotates in the clockwise direction in accordance with the rotation of the driving gear 502. The pin 507 of the rotating drum 509 rotates clockwise in the semicircular slot 331 and moves in the slot 315 of the auxiliary lever 310 as shown in FIG. Accordingly, the operation lever 300 moves from the OFF position to the ON position while the auxiliary lever 310 moves in the clockwise direction.

In this process, the sensor 515 detects the position of the magnet 513 pressed into the blade of the stopper 510, and the microprocessor senses the state of the stopper 510 according to the result. At this time, the microprocessor drives the motor 110 so that the rotational direction of the ring gear 505 is determined according to the sensed result. This minimizes the rotation of the motor 110 in the microprocessor, thereby reducing current consumption.

When the power supply is interrupted by the earth leakage breaker, the operation lever 300 is automatically moved to the OFF position, reset, and then turned on automatically.

9 and 10 are views for explaining the operation of the release lever included in the automatic lever pivoting device according to the embodiment of the present invention.

The release lever 514 is a mechanical component for manually operating the automatic lever rotation device. That is, the position of the stopper 510 is adjusted so that the stopper 510 is not caught by the protrusion 506 in order to manually turn the operation lever 300 on and off.

9, when the automatic lever pivoting device is automatically operated, the stopper 510 is placed in a state of being caught by the protrusion 506, and when the release lever 514 is rotated by 90 degrees, And is placed in a state where it does not get caught in the opening 506.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It can be understood that it is possible.
