The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In one aspect of the embodiment of the present utility model, a power distribution system 01 having a switch 200 is provided, so that the power distribution system 01 to which the switch 200 is applied can have good breaking performance through a new structure of the switch 200.

As shown in fig. 1, the power distribution system 01 includes a switch 200, a dc input module 100 and an output module 300, wherein the switch 200 is electrically connected between the dc input module 100 and the output module 300, so that the dc input module 100 can form a communication circuit with the output module 300 through the switch 200 in a switching-on state. And the switch 200 can also be controlled to switch from a closed state to an open state, so that the circuit is cut off in time when breaking is required.

As shown in fig. 2, the switch 200 includes a breaking body 230 and an actuating mechanism 220, wherein the dc input module 100 can be electrically connected with the output module 300 through a contact assembly 2312 in the breaking body 230, the actuating mechanism 220 is in driving connection with the breaking body 230, specifically, the actuating mechanism 220 can be in driving connection with the contact assembly 2312 in the breaking body 230, so that under the control of the actuating mechanism 220, the breaking body 230 can perform switching on/off, that is, the contact assembly 2312 in the breaking body 230 can perform switching from a switching-on state to a switching-off state, or switching from the switching-on state to the switching-off state, thereby meeting the on/off requirement of the power distribution system 01.

With continued reference to fig. 2, the breaking body 230 rotates around the first direction a, that is, the contact assembly 2312 in the breaking body 230 rotates around the first direction a to realize switching on/off, and the actuating mechanism 220 rotates around the second direction B, that is, the actuating mechanism 220 rotates around the second direction B to realize actuating, and under the condition that the first direction a and the second direction B do not overlap, the breaking body 230 and the actuating mechanism 220 can form a non-coaxial structure, thereby reducing adverse effects caused by assembly errors and effectively improving the breaking performance of the power distribution system 01.

It should be understood that, in order to protect the actuating mechanism 220, a housing is disposed on the outer surface of the actuating mechanism 220 for covering, for example, in fig. 2, the actuating mechanism 220 is located inside a square housing on one side of the breaking body 230, and of course, the form of the housing is not particularly limited, and may be any shape. In addition, the contact assembly 2312 of the present utility model should include a moving contact and a fixed contact that are matched with each other, and of course, the present utility model is not limited to the number of break points of the contact assembly 2312, for example, it may be in various forms such as a single break point structure, a double break point structure, etc., and may be reasonably selected according to practical requirements.

When the first direction and the second direction are not overlapped, the switch 200 can have various forms, so that the actuating mechanism 220 and the breaking body 230 of the switch 200 can have various arrangement modes, and further the switch 200 with various different structural forms can be formed, so as to meet the installation and use of various scenes. Schematic representation: for example the first direction and the second direction may be parallel. For example, the first direction and the second direction may intersect, that is, the rotation central axis of the breaking body 230 intersects the actuating mechanism 220, so as to have an included angle (may be an acute angle, a right angle or an obtuse angle), further, as shown in fig. 2, when the first direction a is perpendicular to the second direction B, the actuating mechanism 220 rotates about the second direction B as an axis during the actuation, and the contact assembly 2312 in the breaking body 230 rotates about the first direction a as an axis during the actuation, that is, the rotation axis of the breaking body 230 is perpendicular to the rotation axis of the actuating mechanism 220 in the extending direction.

Optionally, as shown in fig. 2, the switch 200 may further include an operation handle 210, where the operation handle 210 is in driving connection with the actuating mechanism 220, so that a user may conveniently operate the switch when operations such as manual closing are required. The operating handle 210 may rotate about a third direction, and in particular, the third direction may not overlap the first direction, for example: the third direction is parallel to the first direction, that is, the rotation axis of the operating handle 210 and the rotation axis of the breaking body 230 are parallel to each other; also for example: the third direction intersects the first direction, and may be further perpendicular, that is, the rotation axis of the operating handle 210 is perpendicular to the rotation axis of the breaking body 230 in the extending direction.

Alternatively, the breaking body 230 is formed of a plurality of body assemblies 231, each body assembly 231 has a rotation center axis 2313, the individual bodies 2311 are stacked in the body assemblies 231 along a first direction extending along the rotation center axis 2313, and each of the individual bodies 2311 has a contact assembly 2312 therein, and the contact assemblies 2312 can rotate around the corresponding rotation center axes 2313, thereby achieving breaking and closing. For example, as shown in fig. 2, the breaking body 230 includes three body assemblies 231, each body assembly 231 includes four bodies 2311, and the four bodies 2311 are coaxial and thus have the same rotation center axis 2313, and the four bodies 2311 are arranged in a stacked manner in a first direction a in which the rotation center axis 2313 extends. Further, as shown in fig. 2, the actuating mechanism 220 and the breaking body 230 are arranged along the second direction B perpendicular to the first direction, so that the plurality of bodies 2311 in the body assembly 231 are closer to the actuating mechanism 220, and adverse effects caused by assembly errors when the plurality of bodies 2311 and the actuating mechanism 220 are driven can be conveniently relieved.

Optionally, the body assemblies 231 are disposed in a direction perpendicular to the first direction. For example, as shown in fig. 2, the breaking body 230 includes three body assemblies 231 arranged along a second direction B perpendicular to the first direction a, each body assembly 231 being coaxial, i.e., having a rotation center axis 2313, the rotation center axis 2313 extending along the first direction a, and since the three body assemblies 231 are arranged along the second direction B, the number of coaxial bodies 2311 within each body assembly 231 can be reduced when the same number of individual bodies 2311 are arranged.

Alternatively, as shown in fig. 2, the breaking body 230, the actuating mechanism 220 and the operating handle 210 are sequentially stacked in a direction perpendicular to the first direction, and may form a front-operating structure, that is, the operating handle 210, the actuating mechanism 220 and the breaking body 230 are arranged in a second direction B perpendicular to the first direction a.

Alternatively, the lamination direction of the breaking body 230 and the actuating mechanism 220 may intersect or be perpendicular to the lamination direction of the actuating mechanism 220 and the operating handle 210, whereby a side operating structure may be formed.

For example: when the first direction is parallel to the second direction, a structure of side operation may be formed, that is, the actuating mechanism 220 and the breaking body 230 are arranged along a direction perpendicular to the first direction, the operating handle 210 and the actuating mechanism 220 are arranged along the second direction, or a structure of front operation may be correspondingly formed, that is, the operating handle 210, the actuating mechanism 220 and the breaking body 230 are arranged along a direction perpendicular to the first direction.

Optionally, as shown in fig. 1, the power distribution system 01 further includes a control module 400, where the control module 400 may form an electrical connection relationship with the switch 200, so that the switch 200 may be controlled by the control module 400, in other words, the switch 200 may be switched from a closed state to an open state under the control of the control module 400, so as to implement a function of remotely controlling the open state, so that when a circuit of the power distribution system 01 fails, the circuit is conveniently cut off in time, and a device is protected.

In actual use, when the input module or the output module 300 fails, the control module 400 responds in time and sends a failure signal to the switch 200, so that the switch 200 can quickly switch from a closing state to a separating state after receiving the failure signal, and the circuit is cut off.

Alternatively, the control module 400 may have a capacitive module that may be charged by the power distribution system 01 when the power distribution system 01 is on. When the power distribution system 01 breaks down and the circuit is required to be disconnected, the capacitor module of the control module 400 discharges and releases energy, so that a fault signal is sent to the switch 200, and the switch 200 acts in time after receiving the fault signal, so that the circuit is cut off. After the fault is removed, the switch 200 can be switched on again, so that a circuit of the power distribution system 01 is switched on, and at the moment, the capacitor module is charged again, so that a fault signal can be sent to the switch 200 in time in a discharging energy-releasing mode when the next fault occurs.

Alternatively, to ensure that the switch 200 is able to be accurately opened, the energy released by the capacitive module should be sufficient to overcome the resistance to drive the switch 200 to perform the opening action. The actuating mechanism 220 of the switch 200 may further have an energy storage element, that is, when the switch 200 is switched from the switching-off state to the switching-on state, the energy storage element can store energy, and when the switch 200 is released from the switching-on state in a tripping manner, the energy storage element can release energy, so that the energy is utilized to drive the switch 200 to be switched from the switching-on state to the switching-off state, that is, to drive the contacts in the switch 200 to switch off.

Optionally, when the contact assembly 2312 has a double-breakpoint structure, it has two fixed contacts that can be switched on or off with the same moving contact, and when the output module 300 is electrically connected to the switch 200, a portion of the output module 300 can be fixedly connected to the switch 200, so that the connection between the two fixed contacts is relatively stable. For example, the output module 300 may be directly soldered to a stationary contact of the switch 200.

Optionally, when the contact assembly 2312 is in a double-breakpoint structure, it has two fixed contacts that can be switched on or off with the same moving contact, when the dc input module 100 is electrically connected with the switch 200, the dc input module 100 can be connected with the switch 200, and the dc input module 100 is connected with another fixed contact of the switch 200 through a wire, thereby improving flexibility in connection and being convenient for adapting to various wiring environments. When realizing the connection of wire and stationary contact, can carry out the wiring through the mode of screw fastening to this, can guarantee the stability of wiring.

Optionally, as shown in fig. 3, the power distribution system 01 further includes a box 500, and protection may be provided for a part of the structure of the power distribution system 01 through the box 500. For example, as shown in fig. 3, the operating handle 210 of the switch 200 is disposed at the outer side of the case 500, thereby facilitating the manual operation of the user, and the breaking body 230, the actuating mechanism 220 and the output module 300 of the switch 200 are disposed at the inner side of the case 500, thereby protecting the components from the external interference by the case 500.

Optionally, since the operation handle 210 needs to be inserted into the case 500, a rubber gasket may be disposed between the case 500 and the operation handle 210, so that the insulation degree between the inside and the outside of the case 500 can be improved, and the protection capability of the case 500 can be further improved.

Alternatively, as shown in fig. 3, a plurality of switches 200 may be arranged side by side on the same side of the case 500. Of course, in other embodiments, the plurality of switches 200 may be distributed on different sides of the case 500, and the specific arrangement may be selected according to the actual environment.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
