[0030] In the power system, in order to facilitate the installation of power equipment and save its installation space, multiple circuit breakers are usually integrated in the same housing and controlled by a control structure to form a power distribution device. In the prior art, in order to improve the scene adaptability and wide application of the control structure, connecting terminals are respectively set on the opposite sides of the control module, so that at least two control modules can be electrically connected in sequence through the connecting terminals, thereby changing the number of bits of the control structure to match different numbers of circuit breakers. However, the use of connecting terminals may cause the problem of unreliable control signal connection between control modules. In view of this, the present application is specially proposed.

[0031] In one aspect of the embodiment of the present application, please refer to Figure 1 and Figure 2 , a control pole connection system 100 is provided, comprising: a base 130, a sampling pole connecting plate 110 arranged on the base 130, at least two control modules 120 and a circuit breaker (not shown in the figure), the sampling pole connecting plate 110 is provided with a first control interface 111, the control module 120 is provided with a second control interface 121 cooperating with the first control interface 111, at least two control modules 120 are electrically connected to the sampling pole connecting plate 110 through the first control interface 111 and the second control interface 121 respectively, so as to realize the connection of control signals between the control modules 120, and the control module 120 is also electrically connected to the circuit breaker.

[0032] The sampling pole connecting plate 110 is arranged on the base 130, and can be fixed on the base 130 by screws, clamping, etc., which is not limited in this embodiment. At least two control modules 120 are arranged on the sampling pole connecting plate 110, and each control module 120 is connected to the first control interface 111 on the sampling pole connecting plate 110 through the second control interface 121, thereby realizing the electrical connection with the sampling pole connecting plate 110, and at least two control modules 120 are also electrically connected through the sampling pole connecting plate 110, thereby completing signal transmission and feedback connection. At the same time, the control module 120 is also electrically connected to the corresponding circuit breaker, thereby realizing the control of the circuit breaker.

[0033] In order to facilitate the layout of other components such as circuit breakers and terminal modules 200 in the power distribution equipment, preferably, at least two control modules 120 are distributed in sequence on the sampling pole connecting plate 110 along the length direction of the sampling pole connecting plate 110 (direction A in the figure), and the sampling pole connecting plate 110 extends from the first pole control module 120 to the last pole control module 120 to complete signal transmission and feedback connection.

[0034] The control pole connection system 100 is provided with a sampling pole connection plate 110 on the base 130, so that at least two control modules 120 are electrically connected to one sampling pole connection plate 110 at the same time, and are electrically connected to each other through the sampling pole connection plate 110. The provision of the sampling pole connection plate 110 can effectively improve the reliability of the control signal connection between the control modules 120.

[0035] Optionally, in one implementable manner of the embodiment of the present application, the control module 120 is located above the sampling electrode connecting plate 110 , and the second control interface 121 is plug-in connected to the first control interface 111 .

[0036] The control module 120 is plug-in connected to the sampling electrode connecting plate 110 above the sampling electrode connecting plate 110, which facilitates the installation and removal of the control module 120 and also makes the connection between the two more reliable.

[0037] Optionally, in an implementable manner of the embodiment of the present application, the number of second control interfaces 121 on each control module 120 is at least two, and at least two second control interfaces 121 are distributed along the width direction (direction B in the figure) of the control module 120. Such an arrangement can further improve the reliability of the connection between the control module 120 and the sampling pole connecting plate 110.

[0038] For example, the number of the second control interfaces 121 on each control module 120 is two, and the two second control interfaces 121 are symmetrically distributed with respect to the midpoint of the lower surface of the control module 120 in the width direction of the control module 120 .

[0039] For example, when the control module 120 is a 1P+N or 1P control module 120, the second control interface 121 is distributed in a rectangular array on the lower surface of the control module 120; when the control module 120 is a 2P, 3P or 4P control module 120, the second control interface 121 is distributed in a pole number on the lower surface of the control module 120.

[0040] Optionally, in one possible implementation of the present application, please refer to Figure 3 A cutting line 112 is provided on the sampling electrode connecting plate 110 , and the sampling electrode connecting plate 110 can be cut off along the cutting line 112 .

[0041] The setting of the cutting line 112 makes the local area of ​​the sampling electrode connecting plate 110 thinner. When an external force acts near the cutting line 112, the sampling electrode connecting plate 110 can be cut along the cutting line 112 at the location of the cutting line 112. The setting of the cutting line 112 allows the user to cut the sampling electrode connecting plate 110 according to needs, so as to match different application solutions.

[0042] For example, the cutting line 112 extends along the width direction of the sampling electrode connecting plate 110 to two opposite edges of the sampling electrode connecting plate 110 .

[0044] The length of the control module 120 refers to the size of the control module 120 in the length direction (direction A in the figure) of the sampling electrode connecting plate 110. A cutting line 112 is correspondingly set between two adjacent control modules 120. In actual application, the sampling electrode connecting plate 110 can be cut according to the number of control modules 120 to remove the part not connected to the control module 120, so as to match the application scheme.

[0045] Optionally, in one implementable manner of the embodiment of the present application, a protective plate 140 is provided on the sampling electrode connecting plate 110 , and the protective plate 140 is fixedly connected to the base 130 to fix the sampling electrode connecting plate 110 on the base 130 .

[0046] The protective plate 140 is located on the side of the sampling pole connecting plate 110 facing the control module 120. The protective plate 140 can be fixed on the base 130 by means of screws, clamping, etc. The sampling pole connecting plate 110 is clamped between the protective plate 140 and the base 130 to achieve fixation. The protective plate 140 can fix the sampling pole connecting plate 110 on the base 130 on the one hand, and can also protect the sampling pole connecting plate 110 on the other hand. It can be understood that a through hole should be provided on the protective plate 140 to expose the first control interface 111 on the sampling pole connecting plate 110 so that the first control interface 111 can be connected to the second control interface 121 on the control module 120.

[0047] Optionally, the protective plate 140 is arranged in close contact with the sampling electrode connecting plate 110, and a plurality of through holes are provided on the protective plate 140, and the plurality of through holes are arranged one-to-one corresponding to a plurality of first control interfaces 111 on the sampling electrode connecting plate 110, and the first control interface 111 extends out of the surface of the protective plate 140 through the through holes, thereby being connected to the second control interface 121 on the control module 120.

[0048] Optionally, in one possible implementation of the present application, please refer to Figure 4 A first sampling terminal 113 is provided on the sampling electrode connecting plate 110, and the first sampling terminal 113 is used to be electrically connected to the second sampling terminal 210 of the terminal module 200, so as to transmit the sampled data signal and the corresponding control instruction of the cloud platform.

[0049] For example, the first sampling terminals 113 include multiple pairs, which are spaced apart along the length direction of the sampling electrode connecting plate 110 , and the two sampling terminals in each pair of first sampling terminals 113 are electrically connected to the second sampling terminals 210 of the terminal modules 200 on both sides of the control module 120 .

[0051] Each control module 120 is provided with a signal control board 122 and a logic processing control board 123, and at least two control modules 120 share a sampling pole connecting board 110. Among them, the signal control board 122 is used to be electrically connected to the circuit breaker. It can feedback the corresponding parameters and data by linking the sensors of each module inside the circuit breaker, and control the opening and closing operations of the circuit breaker at the same time, so as to realize the control function of the control module 120. The logic processing control board 123 is electrically connected to the signal control board 122. The logic processing control board 123 is the brain information processing center of the control module 120, which is used to realize the processing function of the control module 120.
