[0002] The disconnector has a certain on-off capacity. It is a device that isolates the de-energized part from the energized part and creates an obvious disconnection point to isolate faulty equipment or perform maintenance on de-energized equipment. There are various types of disconnectors. In the prior art, a disconnector with energy storage is adopted.

These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used to explain the operation principle of the embodiments in combination with the relevant descriptions in the specification.

[0029] The present utility model will be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] Referring to Figures 1 to 6 As shown, a disconnector compatible with multiple operation modes provided in this embodiment includes an operation module 10 and a contact module 20; the operation module 10 is drivingly connected to the contact module 20 to drive the contact module 20 to perform opening and closing operations; wherein, the operation module 10 includes an operation handle 11, an operation housing 12, and a driving shaft 13, an energy storage component 14, and an electric driving component 15 assembled in the operation housing 12. The driving shaft 13 is rotatably assembled in the operation housing 12; a side operation connection part 16 and a front operation connection part 17 that are respectively linked with the driving shaft 13 are arranged on the operation housing 12. Specifically, in this embodiment, the side operation connection part 16 and the front operation connection part 17 are respectively located on different surfaces of the operation housing 12. The side operation connection part 16 refers to a structure coaxially arranged with the driving shaft 13. For example, in this embodiment, the side operation connection part 16 is the end part of the driving shaft 13 extending outside the operation housing; the front operation connection part 17 is not coaxially arranged with the driving shaft 13; the operation handle 11 can be selectively assembled on the side operation connection part 16 or the front operation connection part 17; the energy storage component 14 is linked with the driving shaft 13, and the driving end of the electric driving component 15 acts on the energy storage component 14 to drive the energy storage component 14 to perform energy storage operation.

[0031] The working principle is as follows: When manual operation is adopted for switching, the operation handle 11 is assembled on the side operation connection part 16 or the front operation connection part 17. As Figure 1 shown, the operation handle 11 is assembled on the side operation connection part 16, and as Figure 2 shown, the operation handle 11 is assembled on the front operation connection part 17; by rotating the operation handle 11, the driving shaft 13 is driven to rotate. When the driving shaft 13 starts to rotate, the energy storage component 14 is compressed for energy storage. When the energy storage component 14 completes energy storage, it starts to release, instantaneously connecting or disconnecting the contact module 20; when electric drive is adopted, the electric driving component 15 is directly controlled to act, so that the electric driving component 15 acts on the energy storage component 14 to make the energy storage component 14 perform compression energy storage. When the energy storage component 14 completes energy storage, it starts to release, instantaneously connecting or disconnecting the contact module. The electric operation mode can complete the switching instantaneously, can quickly pull the electric arc, and is especially suitable for centralized photovoltaic power stations distributed in deserts, gobi, wastelands and other places where direct current is applied. It can realize remote millisecond-level rapid on-off of the switch and realize energy consumption control.

[0032] The operation module 10 simultaneously adopts the electric drive mode of the electric drive component 15 and the manual drive mode of the operation handle 11, and the operation handle 11 can be selectively assembled on the side operation connection part 16 or the front operation connection part 17; multiple operation modes of the operation module are realized and can be selected according to the actual situation; the product is more flexible in use. For example, when the side of the operation housing 12 is blocked during the assembly of the disconnector, the operation handle 11 can be assembled on the front operation connection part 17; if the front of the operation housing 12 where the front operation connection part 17 is provided is blocked, the operation handle 11 can be assembled on the side operation connection part 16 on the side. Or the electric drive component 15 can be selected for drive switching.

[0033] The side operation connection part 16 is the end of the drive shaft 13 extending outside the operation housing 12; that is, the side operation connection part 16 is directly constituted by the end of the drive shaft 13. And the end of the drive shaft 13 extending outside the operation housing 12 has a plug hole (defined as the first plug hole 161).

[0034] The front operation connection part 17 includes a first bevel gear 171 and a second bevel gear 172. The first bevel gear 171 is sleeved on the drive shaft 13, and the second bevel gear 172 is perpendicular to and meshes with the first bevel gear 171; an installation hole 173 is opened on the second bevel gear 172, and a plug hole (defined as the second plug hole 121) corresponding to the installation hole 173 of the second bevel gear 172 is opened on the operation housing 12 (specifically, the upper side of the operation housing 12).

[0035] The operation handle 11 includes a handle 111 and a plug column 112 connecting the handle 111. The operation handle 11 is inserted into the plug hole 161 of the side operation connection part 16 or the installation hole 173 of the front operation connection part 17 through the plug column 112; rapid installation is realized. Of course, in other embodiments, the installation structure of the operation handle 11 is not limited to this, and it can also be installed by means such as clamping.

[0036] Furthermore, the operation housing 12 is a transparent housing; with such a setting, a visualization window can be formed, and the on-off state of the switch can be directly confirmed to ensure the personal safety of the operator.

[0037] In this embodiment, the energy storage assembly 14 includes an active swing arm 141, an energy storage spring 143, a connecting rod 144, and a driven swing arm 142. Two active swing arms 141 are provided and are sleeved on the drive shaft 13 at intervals. Specifically, the two active swing arms 141 are integrally connected structures to ensure that their relative positions will not change. The driven swing arm 142 is hinged inside the operation housing 12. The energy storage spring 143 is sleeved on the driven swing arm 142. The driven swing arm 142 is also provided with a long slot, and the connecting rod 144 passes through the long slots of the two active swing arms 141 and the driven swing arm 142. The driving end of the electric drive assembly 15 is matched with the connecting rod 144. With such a setting, when the electric drive assembly 15 acts, it acts on the connecting rod 144, drives the active swing arm 141 to swing through the connecting rod 144, and then compresses the energy storage spring 143.

[0038] Furthermore, the electric drive assembly 15 includes a first electromagnetic driver 151, a second electromagnetic driver 152, and a limiting member 153. The first electromagnetic driver 151 and the second electromagnetic driver 152 are fixed on both sides of the moving direction of the connecting rod 144. The limiting member 153 is connected between the first electromagnetic driver 151 and the second electromagnetic driver 152. The limiting member 153 is provided with a limiting notch 154, and the connecting rod 144 is received in the limiting notch 154. In this embodiment, the first electromagnetic driver 151 and the second electromagnetic driver 152 are fixed on the left and right sides of the connecting rod 144. When the energy storage assembly 14 is in the closing position and it is necessary to drive the energy storage assembly 14 to store energy before opening, the first electromagnetic driver 141 pulls the limiting member 143 to translate leftward (at this time, the second electromagnetic driver 142 does not work), thereby driving the energy storage assembly 14 to swing leftward to achieve energy storage before opening. When the energy storage assembly 14 is in the opening position and it is necessary to drive the energy storage assembly 14 to store energy before closing, the second electromagnetic driver 152 pulls the limiting member to translate rightward (at this time, the first electromagnetic driver 151 does not work), thereby driving the energy storage assembly 14 to swing rightward to achieve energy storage before closing. With such a setting, there is sufficient installation space and it will not interfere with the movement trajectories of the active swing arm 141, the energy storage spring 143, and the driven swing arm 142 of the energy storage assembly.

[0039] A limiting plate 18 is also fixed inside the operation housing 12. An arc-shaped limiting groove 181 is formed on the limiting plate 18, and the connecting rod 144 is restricted in the arc-shaped limiting groove 181 to prevent the energy storage assembly 14 from swinging excessively and deviating from its position, and the accuracy of the action can be better guaranteed.

[0040] Specifically, in this embodiment, the number of operation modules 10 is one, and the number of contact modules 20 is multiple. The multiple contact modules 20 are sequentially spliced on the back of the operation module 10, and the operation module 10 drives the multiple contact modules 20 to act simultaneously. The operation module 10 and the contact module 20 are both independent structures, so that free combination can be achieved; for example, multiple contact modules 20 can be spliced on the front and back of the operation module 10 at the same time, etc.

[0041] Specifically, the contact module 20 includes a contact housing 21, a connecting shaft 22, a moving contact 23, a static contact 24, and a wiring board 25. The connecting shaft 22 is rotatably assembled in the contact housing 21. The end of the connecting shaft 22 extends out of the contact housing 21 and is used to connect to the driving shaft 13. The moving contact 23 is fixed on the connecting shaft 22. The static contact 24 is fixed in the contact housing 21 and corresponds to the moving contact 23. The wiring board 25 is fixed on the contact housing 21 and extends outward. The wiring board 25 is connected to the static contact 24 through a flexible connection 26; in this way, the wiring board 25 and the static contact 24 can be independently arranged without interfering with each other; compared with the prior art in which the wiring board 25 and the static contact 24 are rigidly connected, it is possible to avoid the influence of the extrusion stress between copper bars on the position of the static contact 24 when the external copper bars are lapped, thereby affecting the closing of the moving and static contacts 24. And even if the external wiring piece 25 becomes loose or deformed, the contact between the internal moving and static contacts will not be affected.

[0042] At the same time, a rotating bearing 27 is assembled on the wiring board 25, and the wiring board 25 is rotatably assembled on the contact housing 21 through the rotating bearing 27; such a setting can select horizontal wiring or vertical wiring according to the actual environment of the customer, and the wiring operation is more convenient.

[0043] Furthermore, the front of the contact housing 21 has a transparent window 211, and this transparent window 211 also forms a visualization window, through which the on-off situation inside can be directly confirmed; ensuring the personal safety of the operator.

[0044] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
