Description

Technical Field

[0001] The present application relates to the field of low-voltage switchgear, and specifically to an intelligent circuit breaker. Background Art

[0002] Whether it is for small circuit breakers or molded case circuit breakers, intelligent development is an inevitable trend.

[0003] There is a kind of reclosing circuit breaker with electric operation, such as a residual current operated protection circuit breaker disclosed in CN204102832U, which includes a motor, a transmission mechanism, a circuit board and an operating mechanism built in it. This circuit breaker can be opened and closed by electric means (motor transmission) or manually. When it is necessary to open and close the circuit manually, the user can insert the hexagonal wrench into the handle socket (the handle socket is exposed on the top cover of the circuit breaker) to operate.

[0004] However, the above-mentioned circuit breaker does not have an area for placing the external handle (hexagonal wrench) on its shell, so generally the hexagonal wrench needs to be prepared by the customer himself, or stored in the packaging box of the circuit breaker as an accessory for sale.

[0005] Such a structure is extremely disadvantageous for users, because the external handle may be lost when placed in the packaging box as an accessory; or after the user operates the circuit breaker, the external handle has nowhere to be placed.

[0006] Therefore, how to redesign the circuit breaker structure so that the circuit breaker structure has a storage structure for an external handle is also a direction worthy of research. Summary of the invention

[0007] In view of this, the purpose of this application is to overcome the deficiencies in the prior art and to provide an intelligent circuit breaker.

[0013] With this structure, the first cavity and the second cavity are formed on the upper cover and the cover body respectively, and the two together form a storage groove, which will be beneficial to the processing of the product, and at the same time, the remaining space of the upper cover and the cover body (the space after arranging other components) can be utilized as much as possible.

[0014] In some embodiments of the present application, the external handle includes a first part and a second part, and the first part and the second part are vertically arranged; the first part and the second part are both rod-shaped parts with non-circular cross-sections; the second cavity is used to accommodate the second part and part of the first part; the first cavity is a slot for the rest of the first part.

[0015] With this structure, the first cavity and the second cavity can fully utilize the remaining space of the upper cover and the cover body. At the same time, after the two are assembled, it is easy to form a complete storage slot, which is conducive to the installation of the external handle.

[0016] In some embodiments of the present application, the upper cover includes two long sides and two short sides, the long sides and the short sides surround the top surface in sequence and are connected to the top surface, and the storage slot is arranged next to one of the short sides; the second part is arranged parallel to the short side close to the storage slot.

[0017] With this structure, the storage slot is set at a secondary position, and the space at the edge of the upper cover and the cover body is used as much as possible, so as to avoid the external handle occupying space in other places and reserve more space for the design of other components.

[0018] In some embodiments of the present application, a carrier slot is further provided on the upper cover, and the carrier slot is located beside the storage slot and a long side surface, and the carrier communication module is installed in the carrier slot.

Example

[0043] like Figure 1-Figure 9 As shown, embodiment 1 of the present application provides a circuit breaker, which is an intelligent circuit breaker. Simply put, this circuit breaker is a molded case circuit breaker with electric operation and manual operation.

[0044] The circuit breaker includes a circuit breaker housing, a transmission mechanism 6000, an external handle 7000, a control component 400, a carrier communication module 8000, a contact component, an arc extinguishing component, and the like.

[0045] The circuit breaker housing includes a base 1001, a cover 1002 and an upper cover 1003. Here, the base 1001 is arranged below the cover 1002, and the base 1001 and the cover 1002 are fastened by bolts. The upper cover 1003 is arranged above the cover 1002, and the upper cover 1003 and the cover 1002 are also fastened by bolts (fastened by fasteners 10035, and other fasteners 10035 can also be used for fastening in addition to bolts). Of course, in addition to this, the three can also be fastened by bolts, or other fastening methods can be used. No matter which method is used, as long as the stability of the three structures can be guaranteed.

[0046] The contact assembly, arc extinguishing assembly and other components are arranged between the base 1001 and the cover 1002. The working principle and setting method of the contact assembly, arc extinguishing assembly and other components are common knowledge to those skilled in the art and will not be repeated here.

[0047] The transmission mechanism 6000 is arranged in the space formed by the cover body 1002 and the upper cover 1003. The circuit breaker realizes electric operation and manual operation by relying on the transmission mechanism 6000, but the power source is different; when it is operated electrically, the power is provided by the motor, and when it is operated manually, the power is provided by the external handle 7000. This is a well-known technology for those skilled in the art, and this application will not explain how the transmission mechanism 6000 realizes electric operation and manual operation.

[0048] The transmission mechanism 6000 has an input shaft 6001, on which a handle insertion hole 6001a is provided. An exposed hole 10031 is provided on the top surface 10034 of the upper cover 1003. The external handle 7000 is inserted into the handle insertion hole 6001a through the exposed hole 10031 to realize manual operation.

[0049] A storage slot 1050 is provided on the circuit breaker housing, and a notch of the storage slot 1050 is located on the top surface 10034 of the circuit breaker housing, so that the user can place the external handle 7000 in the storage slot 1050 when not in use, and take it out when needed.

[0050] The storage slot 1050 may be designed in various ways. Here, a relatively simple structure is used as an example:

[0051] like Figure 2-3As shown, a first cavity 1051 is formed on the cover body 1002 , and a second cavity 1052 is formed on the upper cover 1003 , so that when the upper cover 1003 and the cover body 1002 are fixed, the first cavity 1051 cooperates with the second cavity 1052 to form a storage slot 1050 .

[0052] Since the external handle 7000 includes a first part 7001 and a second part 7002 connected to each other, the first part 7001 and the second part 7002 are arranged vertically, and the first part 7001 and the second part 7002 are both rod-shaped parts with non-circular cross-sections. The first cavity 1051 can be made into a slot, so that a part of the first part 7001 is inserted into the slot. The second cavity 1052 can be made to include the second part 7002 and a part of the first part 7001 (here, the part of the first part 7001 refers to the first part 7001 connected to the second part 7002). Such a cavity setting can make full use of the space of the cover body 1002 and the upper cover 1003, which is conducive to the design of the storage slot 1050.

[0053] A hook 1053 is provided at the notch of the storage slot 1050, and the hook 1053 hooks the external handle 7000 so that the external handle 7000 and the storage slot 1050 form a detachable fit. An escape groove 1054 is provided on the storage slot 1050, and the escape groove 1054 extends to the lower part of the external handle 7000, so that the finger enters the escape groove 1054 to hook out the external handle 7000. Here, the hook 1053 and the escape groove 1054 are both provided on the second cavity 1052, that is, the hook 1053 and the escape groove 1054 are both formed with the second part 7002.

[0054] Here, since the upper cover 1003 is also a three-dimensional product, the upper cover 1003 includes two long side surfaces 10032, two short side surfaces 10033 and a top surface 10034 (the top surface 10034 of the upper cover 1003 is the top surface 10034 of the circuit breaker housing), and the long side surfaces 10032 and the short side surfaces 10033 surround the top surface 10034 in sequence and are connected to the top surface 10034. The storage slot 1050 is located near one of the short side surfaces 10033, and the second part 7002 of the external handle 7000 is also arranged parallel to the short side surface 10033. Here, since the upper cover 1003 and the cover body 1002 are fastened by fasteners 10035, and the fasteners 10035 are distributed at the four corners of the top surface 10034 of the upper cover 1003, the storage slot 1050 will be at least between two of the fasteners 10035.

[0055] A carrier slot 10036 is formed on the upper cover 1003, the opening of the carrier slot 10036 is located on the top surface 10034, the carrier communication module 8000 is located in the carrier slot 10036, and a transparent cover is also provided outside the carrier slot 10036. The carrier communication module 8000 here is electrically connected to the control component 400, and can realize communication between the control component 400 and the host computer, mobile terminal, PC or other devices.

[0056] Here, the carrier groove 10036 is arranged near the storage groove 1050 and a long side 10032, and here the position of the first cavity 1051 is different. There are two ways to arrange the carrier groove 10036 and the storage groove 1050. One is as follows: Figure 1 As shown, in this embodiment, the carrier groove 10036 is adjacent to the connection position of the second part 7002 and the first part 7001. Figure 6 As shown, in this embodiment, the carrier groove 10036 is adjacent to the end of the second portion 7002 (the end away from the first portion 7001).

[0057] The top surface 10034 is not a completely flat surface. The top surface 10034 includes a first surface 10034a and a second surface 10034b. The heights of the first surface 10034a and the second surface 10034b are different. The first surface 10034a is higher than the second surface 10034b. The notch of the storage slot 1050 is opened on the second surface 10034b, and the exposed hole 10031 is opened on the first surface 10034a.

[0058] Here, the mechanism installation area of ​​the transmission mechanism 6000 is located on one side of the carrier slot 10036. After the transmission mechanism 6000, the upper cover 1003, etc. are installed, the transmission mechanism 6000 is located on one side of the carrier slot 10036. A slide plate 10037 is also provided in the space formed by the upper cover 1003 and the cover body 1002. The slide plate 10037 here is a sliding arrangement, and the handle plug hole 6001a can be covered or not covered by sliding. In short, the slide plate 10037 has two positions, a first position and a second position. When it is in the first position, the slide plate 10037 is just between the exposed hole 10031 and the handle plug hole 6001a, and when it is in the second position, the exposed hole 10031 is connected with the handle plug hole 6001a. Here, the slide plate 10037 is provided on the transmission mechanism 6000.

[0059] The control component 400 is used to control the operation of the transmission mechanism 6000, specifically by controlling the operation of the motor in the transmission mechanism 6000. Of course, the control component 400 is not limited to a function of controlling the operation, it is also used to realize functions such as overload protection, short circuit protection, and leakage protection.

[0060] In order to achieve interlocking, a switch 10038 is also provided in the motion track of the slide plate 10037. The switch 10038 here is a micro switch. Of course, in addition to the micro switch, a Hall element, a photoelectric sensor switch, an infrared sensor switch, etc. can also be used, as long as they can play a role in position detection. The switch 10038 here is electrically connected to the control component 400. When the slide plate 10037 is in the second position, the switch 10038 can be triggered. After the switch 10038 is triggered, a signal is fed back to the control component 400, and the control component 400 can prohibit the closing operation of the motor, thereby playing a role in interlocking.
