As an example, the plug connector of the line access module 10 may be a female plug, and the plug connector of the power distribution unit plug frame 20 may be a male plug that mates with the female plug.

In some embodiments of the present application, with continued reference to fig. 4 and 5, fig. 5 illustrates a schematic internal structure of a power distribution unit bay 20 according to an embodiment of the present application, where the power distribution unit bay 20 includes:

a mounting frame 27;

a plurality of micro-circuit breakers 24, the micro-circuit breakers 24 are fixed in the mounting frame 27, and the micro-circuit breakers 24 are configured to be connected with corresponding strong electric signal lines and control the on-off of the strong electric signal lines;

the signal acquisition circuit board 28, the signal acquisition circuit board 28 is connected with each miniature circuit breaker 24 and outputs weak current signals corresponding to the strong electric signal lines;

wherein a plurality of miniature circuit breakers 24 are arranged side by side adjacent to a signal acquisition circuit board 28.

Specifically, the mounting frame 27 is internally provided with a cavity so as to provide a mounting carrier for the miniature circuit breaker 24 and the signal acquisition circuit board 28, thereby preventing external dust impurities from affecting the miniature circuit breaker 24 and the signal acquisition circuit board 28, and forming a foundation unit convenient for assembly and integration. In some embodiments of the present application, the mounting frame 27 is approximately regular in shape, such as approximately rectangular or square in shape. It will be appreciated that the mounting frame 27 may also be of other shapes, such as a regular pentagonal cube.

The miniature circuit breaker 24 is used for controlling the on-off of the strong electric signal line connected with the miniature circuit breaker so as to control whether the corresponding electric equipment is electrified or not. In general, the micro circuit breaker 24 has an input end and an output end, a strong electric signal line is connected at the input end and the output end, and a switch structure, for example, a switch structure formed by a fixed contact and a moving contact is arranged between the input end and the output end in the micro circuit breaker 24, and the input end and the output end can be electrically connected when the moving contact is contacted with the fixed contact, so that the strong electric signal line connecting the input end and the output end is communicated; on the contrary, when the moving contact is disconnected from the fixed contact, the input end and the output end are disconnected electrically, so that a strong electric signal line connecting the input end and the output end is disconnected.

Illustratively, the miniature circuit breaker 24 may be a class B miniature circuit breaker 24, a class C miniature circuit breaker 24, or a class D miniature circuit breaker 24.

The signal collection circuit board 28 is used for being connected with each micro breaker 24 and outputting weak current signals corresponding to the strong electric signal lines, for example, the signal collection circuit board 30 can collect current signals of the strong electric signal lines and output weak current signals corresponding to the current signals; for another example, the signal collection circuit board 30 may collect a voltage signal of the strong electric signal line and output a weak electric signal corresponding to the voltage signal; for another example, the signal collection circuit board 30 may collect a voltage signal and a current signal of a strong electric signal line and output a weak electric signal corresponding to the voltage signal and the current signal. The signal acquisition circuit board 28 may be a single-sided circuit board, a double-sided circuit, or a multi-layer circuit board, for example.

The strong electric signal referred to in the present application refers to a voltage signal or a current signal having a voltage, a current, or a power greater than a certain value, for example, a strong electric signal when the voltage value is greater than or equal to 24V, and a weak electric signal when the voltage value is less than 24V. It will be appreciated that the definition of the strong and weak electric signals may be adjusted according to the region of use and the actual scene, and is not limited herein.

In the embodiment of the present application, by installing the plurality of miniature circuit breakers 24 and the signal acquisition circuit board 28 in the installation frame 27, since the signal acquisition circuit board 28 is connected with each miniature circuit breaker 24 and outputs weak current signals corresponding to strong electric signal lines, for current and/or voltage detection of the strong electric signal lines, the weak electric signals output by the signal acquisition circuit board 28 can be provided to the corresponding control units without directly connecting the strong electric signal lines connected with the miniature circuit breakers 24 to the control units. In the case where the line diameter required for weak electric signal transmission is smaller than that required for strong electric signal transmission, on the one hand, it is advantageous to reduce the diameter of the signal transmission line, and on the other hand, the signal acquisition circuit board 28 may also output signals inputted by a plurality of inputted signal transmission lines via the same signal line, so as to reduce the number of signal transmission lines. Therefore, under the condition of reducing the diameter and the number of the signal transmission lines, the size of the AC/DC column cabinet can be further compressed, for example, the size 600mm X2000mm X1000mm of the traditional AC/DC column cabinet can be compressed into the external size 446mm X44.45mm X850mm of the power distribution plug frame unit, so that the height of the AC/DC column cabinet is greatly reduced.

In some embodiments of the present application, the miniature circuit breaker 24 has voltage measurement and current measurement functions, thereby eliminating the need for additional voltage measurement devices (e.g., voltage transformers) and current measurement devices (e.g., current transformers), thereby further reducing the size of the power distribution unit bay 20, for example. Illustratively, the miniature circuit breaker 24 may employ an ASCB1 series intelligent miniature circuit breaker having voltage measurement and current measurement functions.

In some embodiments of the present application, for example, for the embodiment of the micro breaker 24 having the voltage measurement and current measurement functions, the micro breaker 24 has a voltage output portion and a current output portion, the voltage output portion is coupled to the strong electric signal line, and the voltage output portion is coupled to the signal acquisition circuit board 28 to provide the weak electric signal corresponding to the voltage signal in the strong electric signal line to the signal acquisition circuit board 28; the current output portion is coupled to the strong electric signal line, and the current output portion is coupled to the signal acquisition circuit board 28, so as to provide the weak electric signal corresponding to the current signal in the strong electric signal line to the signal acquisition circuit board 28.

Specifically, the voltage output part may be directly connected to the strong electric signal line, for example, the voltage output part has a large resistance, and the large resistance is connected in parallel to the strong electric signal line, so that the high-voltage signal is converted into a small current signal and supplied to the signal acquisition circuit board 28; for another example, the voltage output part may have a voltage transformer sleeved on the strong electric signal line, the voltage signal on the strong electric signal line is measured by the voltage transformer, and the measured weak electric signal is transmitted to the signal acquisition circuit board 28.

The current output part may be directly connected to the strong electric signal line, for example, the current output part has a small resistance, and the small resistance is connected in series to the strong electric signal line, so that the current signal is converted into a small voltage signal and provided to the signal acquisition circuit board 28; for another example, the current output portion may have a current transformer sleeved on the strong electric signal line, the current signal on the strong electric signal line is measured by the current transformer, and the measured weak electric signal is transmitted to the signal acquisition circuit board 28.

In the above embodiment, since the current output portion and the voltage output portion are coupled to the signal collecting circuit board 28, the signal collecting circuit board 28 may receive the voltage signal in the strong electric signal line and the weak electric signal corresponding to the current signal, so that the corresponding control unit plug frame 30 uses the weak electric signal to implement the control of the miniature circuit breaker 24, for example, when a short circuit phenomenon (excessive current) occurs in a strong electric signal line, the control unit plug frame 30 receives the weak electric signal sent by the signal collecting circuit board 28 and determines that the short circuit phenomenon occurs, the signal collecting circuit board 28 may send a control signal for controlling the miniature circuit breaker 24 to open, and the control signal is provided to the corresponding miniature circuit breaker 24 via the collecting circuit board 30 and makes it open, so as to implement the short circuit protection of the distribution unit plug frame 20.

It should be noted that, the logic control of the control unit plug-in frame 30 of the present application may be implemented by a circuit structure, and does not involve a computer program, for example, a comparator may compare the signal level to determine whether a short circuit phenomenon occurs.

In some embodiments of the present application, for example, for embodiments in which the control unit bezel 30 may issue control signals to control the opening of the miniature circuit breaker 24 via the signal acquisition circuit board 28, the signal acquisition circuit board 28 may be connected to the control terminal of the miniature circuit breaker 24 so that the control unit bezel 30 transmits the control signals via the signal acquisition circuit board 28. Specifically, the control end of the micro breaker 24 may refer to a control end of an energizing switch corresponding to an engaging coil of the engaging moving contact, for example, the engaging coil is connected to a MOS tube disposed on a power circuit, a control signal is sent by the control unit plug frame 30 and transmitted to the MOS tube through the signal collecting circuit board 28, and whether the engaging coil is energized is controlled by the MOS tube, so as to control whether the engaging coil is energized and control whether the moving contact is actuated.

In some embodiments of the present application, the micro breaker 24 further has a temperature acquisition portion coupled to the signal acquisition circuit board 28 to provide the signal acquisition circuit board 28 with a weak current signal corresponding to the real-time temperature of the micro breaker 24. Illustratively, the temperature acquisition part may include a temperature sensor, which may be located inside the micro breaker 24 or on the surface of the micro breaker 24, so as to directly measure the temperature inside the micro breaker 24 or on the surface of the micro breaker 24, and determine whether the temperature exceeds a standard by using the control unit bezel 30, thereby controlling the micro breaker 24 to be turned on and off.

In some embodiments of the present application, the plurality of miniature circuit breakers 24 may be arranged side by side along the length or width of the signal acquisition circuit board 28 to reduce the space occupied by the signal acquisition circuit board 28 and the plurality of miniature circuit breakers 24, thereby facilitating further downsizing of the power distribution unit bay 20. In other embodiments of the present application, the plurality of micro-breakers 24 are arranged side by side, and the plurality of micro-breakers 24 are disposed overlapping the signal acquisition circuit board 28, that is, the plurality of micro-breakers 24 may be located below the signal acquisition circuit board 28, or the plurality of micro-breakers 24 may be located above the signal acquisition circuit board 28, thereby reducing the space occupied by the signal acquisition circuit board 28 and the plurality of micro-breakers 24, thereby further reducing the size of the power distribution unit plug frame 20.

Further, in some embodiments of the present application, with continued reference to fig. 1, 6 and 8, fig. 6 shows another side-axis schematic view of the power distribution unit plug frame 20 in the embodiments of the present application, and fig. 8 shows another side-axis schematic view of the control unit plug frame 30 in the embodiments of the present application, where one end of the power distribution unit plug frame 20 facing away from the wire inlet module 10 is provided with a first mounting bracket 26, one end of the control unit plug frame 30 facing away from the wire inlet module 10 is provided with a second mounting bracket 34, and the first mounting bracket 26 and the second mounting bracket 34 are locked in threaded holes of the first side plate 11 and/or the second side plate 12 by screws, so that the power distribution unit plug frame 20 and the control unit plug frame 30 are kept fixed with the wire inlet module 10, and a phenomenon that the power distribution unit plug frame 20 and the control unit plug frame 30 exit the mounting space 14 along the sliding rail 15 is avoided.

It will be appreciated that the power distribution unit plug frame 20 and the control unit plug frame 30 may also be fixed to the incoming and outgoing line module 10 by riveting or welding, etc.

In some embodiments of the present application, with continued reference to fig. 1 and 2, the wire inlet and outlet module 10 has an air outlet 16 and a cooling fan 17 mounted at the air outlet 16, and the surface of the wire inlet and outlet module 10 is provided with a plurality of air inlet holes 18 communicating with the interior thereof. Specifically, when the cooling fan 17 works, air can enter the inside of the wire inlet and outlet module 10 from the plurality of air inlet holes 18, cool the power wire inside the wire inlet and outlet module 10 in the air flowing process, and finally be discharged through the air outlet 16, so that the purpose of cooling the wire inlet and outlet module 10 is achieved, and the phenomenon that the temperature of the wire inlet and outlet module 10 is too high in the working process is avoided.

Further, in some embodiments of the present application, with continued reference to fig. 1, 2, and 4, the air inlet 18 is located at the unit mating end 102 of the wire inlet module 10; the end of the power distribution unit plug frame 20 adjacent to the incoming and outgoing line module 10 is provided with a plurality of first through holes 23, and the plurality of first through holes 23 are opposite to at least part of the air inlet holes 18. It should be noted that, since the plurality of first through holes 23 are opposite to at least part of the air inlet holes 18, when the cooling fan 17 works, air inside the power distribution unit plug frame 20 can flow into the air inlet holes 18 from the first through holes 23, so that the cooling fan 17 can drive air inside the power distribution unit plug frame 20 to flow when working, and finally, the cooling fan 17 is utilized to simultaneously cool the power distribution unit plug frame 20 and the wire inlet/outlet module 10.

More specifically, with continued reference to fig. 6, the end of the power distribution unit bay 20 facing away from the in-out line module 10 has a plurality of miniature circuit breakers 24 arranged side-by-side with a vent gap 25 (e.g., a 2mm gap) between adjacent miniature circuit breakers 24. That is, when the cooling fan 17 drives the air inside the power distribution unit insert frame 20 to flow, the air flows in from the ventilation gap 25 at one end of the power distribution unit insert frame 20, then flows inside the power distribution unit insert frame 20 and flows out through the first through hole 23, so that the air completely flows through the power distribution unit insert frame 20, which is beneficial to improving the heat dissipation efficiency of the power distribution unit insert frame 20.

Illustratively, the micro-breaker 24 may be a 1P micro-breaker or a 3P micro-breaker, while the micro-breaker 24 is hot pluggable in a closed state as needed to facilitate daily use and maintenance of the modular power system.

In some embodiments of the present application, with continued reference to fig. 1, 2 and 8, the control unit plug frame 30 has a plurality of second through holes 33 at an end adjacent to the incoming and outgoing line module 10, and the plurality of second through holes 33 are opposite to at least part of the air inlet holes. Similarly, since the plurality of second through holes 33 are opposite to at least part of the air inlet holes, when the cooling fan 17 works, air inside the control unit plug frame 30 can flow into the air inlet holes from the second through holes 33, so that the cooling fan 17 drives air inside the control unit plug frame 30 to flow, and finally, the cooling fan 17 is utilized to simultaneously cool the control unit plug frame 30 and the wire inlet and outlet module 10.

It should be noted that the foregoing description of the modular power system is intended to clearly illustrate the implementation verification process of the present application, and those skilled in the art may also make equivalent modification designs under the guidance of the present application, for example, a through hole may be provided at one end of the control unit plug frame 30 facing away from the wire inlet and outlet module 10, when the cooling fan 17 drives the air inside the control unit plug frame 30 to flow in from the through hole at one end of the control unit plug frame 30, and then flow through the inside of the control unit plug frame 30 and flow out through the through hole, so that the air completely flows through the control unit plug frame 30 and improves the cooling efficiency of the control unit plug frame 30.
