Problems solved by technology

[0003] In the circuit breaker in the prior art, the circuit breaker is closed by the forward rotation of the motor control driving device, and then the circuit breaker is opened by the reverse rotation of the motor control drive device. Therefore, during the opening and closing action of the circuit breaker, the motor needs Turning in two directions to realize opening and closing has high requirements for motor control. During the opening and closing process, the gears are not in place when meshing or the motor itself is stuck during the action process. When the circuit breaker is tripped and opened Cause the circuit breaker to fail to open and close normally

Embodiment 1

[0083] The circuit breaker provided in this embodiment, such as figure 1 with figure 2 As shown, it includes: an operating structure and a contact mechanism 2 , wherein the contact mechanism 2 has a static contact 21 and a moving contact 22 , and the moving contact 22 is linked to the operating handle 18 and the tripping mechanism 14 .

[0084] Such as figure 1 As shown, the operating structure includes a driver 11 ; a first gear 12 , a second gear 13 , a tripping mechanism 14 , a detection device and a controller 162 . Such as figure 1 As shown, the first gear 12 is driven by the driver 11 to rotate; the second gear 13 and the tripping mechanism are respectively linked with the operating handle 18; the detection device is used to at least detect whether the user owes electricity charges and whether the first gear 12 is in the closing position or the opening position; the controller 162 controls the driver 11 to drive the first gear 12 to rotate forward, reverse or stop ac...

Embodiment 2

[0113] This embodiment provides an operating structure of a circuit breaker, which differs from the operating structure of the circuit breaker provided in Embodiment 1 in that:

[0114] The pressing member 124 is disposed on the first gear 12 , as long as the pressing member 124 can be opposite to the first meshing portion 121 to ensure that the pressing member 124 can be linked with the tripping mechanism 14 when the first gear 12 rotates.

[0115] As a deformation of the shape of the pressing piece 124 , the pressing piece 124 can also be a circular, square protrusion or convex portion, as long as the pressing piece 124 can be linked with the tripping mechanism 15 .

[0116] As a modification of the connection mode between the third gear 16 and the driver 11, the third gear 16 can also be directly connected to the driver 11, and the first gear 12 and the third gear 16 rotate coaxially, so that the driver 11 drives the first gear 12 to rotate. Can.

Embodiment 3

[0118] This embodiment provides an operating structure of a circuit breaker, which differs from the operating structure of the circuit breaker provided in Embodiment 1 or Embodiment 2 in that:

[0119] The free end that the torsion spring cooperates with the mounting shaft is ring-shaped, and a hole is arranged on the mounting shaft, and the ring-shaped torsion spring is fixed in the hole of the mounting shaft by fasteners such as bolts. The free end that the torsion spring cooperates with the installation shaft can also be a bent end that directly extends into the top structure of the installation shaft.

[0120] As a structural modification of the biasing member 142, the biasing member 142 may also use a tension spring.

[0121] As a first alternative embodiment, the trip link 141 includes a first body and a second body arranged at an obtuse angle, the two ends of the first body are respectively the connection end 1413 and the installation end 1412, and the two ends of the s...

Abstract

The invention discloses an operating structure comprising a driver; a first gear driven by the driver; a second gear in tandem with an operating handle; a tripping mechanism in tandem with the operating handle; a detecting device for detecting the power consumption condition of a user and the position of the first gear; and a controller that controls the rotation of the driver. The invention alsodiscloses a control method based on the operating structure. The method controls the rotation of the driver by detecting whether a user owes the electricity fee and detecting the position of the firstgear. The invention discloses a circuit breaker comprising the operating structure and a contact mechanism. The operating structure can reduce the probability of stuck phenomena caused by the two-wayrotation of a motor, thereby realizing a function of automatically tripping out in case of defaulting and automatically switching on in case of recharging.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an operating structure of a circuit breaker, a circuit breaker and a control method. Background technique [0002] According to the needs of my country's power supply network intelligence, the State Grid Corporation of China requires the power supply network intelligence. Therefore, it is necessary for the terminal actuator of the power supply network - the miniature circuit breaker (or miniature circuit breaker) to execute the upper-end signal and have the functions of tripping and closing. Therefore, the current development trend of miniature circuit breakers is that in addition to the traditional manual opening and closing and over-current and overload automatic tripping functions, it also needs to have an electric opening and closing function (commonly known as automatic opening and closing function) to achieve remote control; especially It is a combination of smart ...
