Referring to fig. 1 to 4, a power supply module for professional performance according to an embodiment of the present invention includes a housing 10; the bus bar 20, the bus bar 20 is fixed in the casing 10, and two ends of the bus bar 20 extend to the outer sides of two ends of the casing 10 for introducing an external power supply; each group of socket assemblies comprises an output socket, and the output socket of each group of socket assemblies is connected with the bus bar 20; the power-on indicating unit comprises an indicating lamp assembly 31 and a plurality of contactors which are connected in series on the same loop; each contactor controls the contact to be closed when the output socket corresponding to the contactor is successfully connected to the performance equipment through an external cable; an indicator light assembly 31 is provided on the housing 10 and is adapted to be illuminated when the contacts of all of the contactors in the circuit are closed. Optionally, both ends of the bus bar of the current power supply module may also be connected to bus bars of other different power supply modules, respectively, so as to implement the series connection of the plurality of power supply modules. Therefore, the pluggable bus bar is adopted, so that the connection operation is simpler, and the success rate and the installation efficiency of multi-module connection are improved.
In this embodiment, the indicator light assembly 31 includes a first indicator light 311 and a second indicator light 312, and the first indicator light 311 and the second indicator light 312 are respectively disposed on the side surfaces 10a at both ends of the housing 10.
It should be understood that the power supply module shown in any one of fig. 1-4 is one possible example, and the power supply module may include one or more sets of socket assemblies, and is not limited in particular. It can be seen that the power supply module shown in any one of fig. 1 to 4 includes three socket assemblies, and in the following, any one set of socket assemblies 40 included in the power supply module is taken as an example for description, and in this case, the output socket 401 included in the socket assembly 40 corresponds to the contactor 60.
Optionally, as shown in fig. 1, the output socket 401 is disposed on the top surface of the housing 10, and the top surface of the housing 10 is vertically connected to the side surfaces 10a at the two ends of the housing; alternatively, the output socket 401 included in the socket module 40 may be provided on an inclined surface (not shown) of the housing 10, the inclined surface of the housing 10 may be provided at an obtuse angle with respect to the bottom surface of the housing 10, and the inclined surface of the housing 10 may be in contact with both side surfaces 10a of the housing 10.
In addition, the outlet assembly 40 may further include a dimming/through band conversion unit 403. The dimming/through band converting unit 403 includes a switch 4031 and a dimmer 4032, the switch 4031 is configured to select one power supply channel from a through power supply channel and a dimming power supply channel to supply power to the performance device connected to the output socket 401, the through power supply channel is configured to directly connect the output socket 401 with any one of the phase lines a, B, and C, the dimming power supply channel is configured to connect the output socket 401 with any one of the phase lines a, B, and C through the dimmer 4032, and the dimmer 4032 is configured to adjust a power supply voltage of the output socket 401, so as to implement a dimming operation on the performance device connected to the output socket 401. The transfer switch 4031 may be implemented by a controlled device having a switching function, such as an electromagnetic relay, a thyristor, or other conventional devices, and the dimmer 4032 may be implemented by a conventional thyristor dimmer, a digital dimmer, or other conventional devices.
As shown in fig. 2, in the housing 10 of the power supply module, hardware such as the conversion unit 4031 and the dimmer 4032 can be connected to the circuit board 50, and the circuit board 50 is connected to the bus bar 20 to introduce power.
In the present embodiment, the bus bar 20 includes a phase line a, a phase line B, and a phase line C. The receptacle assembly 40 also includes a leakage protection switch 402; one end of the leakage protection switch 402 is connected to the output socket 401, and the other end of the leakage protection switch 402 is connected to any one of the phase lines a, B, and C.
It can be understood that, since the power supply module usually adopts three-phase ac power, and the lighting device (such as a performance lamp) adopts a single-phase power supply, the output socket 401 only needs to be connected to any phase line, so as to increase the 220V single-phase power supply for the lighting device connected thereto, so as to meet the power utilization safety specification. In addition, a leakage protection switch 402 is arranged between the output socket 401 and the phase line, so that the output socket can be disconnected from the phase line when the output working voltage of the output socket 401 is abnormal, the voltage protection effect is achieved, and the safety of an operator is ensured.
In addition, the bus bar 20 further includes a neutral line, and as shown in fig. 4, the loop includes a positive connection terminal 61 and a negative connection terminal 62, the positive connection terminal 61 is connected to the output socket 401, and the negative connection terminal 62 is connected to the neutral line. Further, the contactor 60 is connected to the outlet socket 401 by a branch circuit for transmitting an electrical signal to the contactor 60 when the outlet socket 401 is successfully connected to the presentation device through an external cable, so as to energize the contactor 60 and control the contact of the contactor 60 to close. It will be appreciated that the contacts of the contactor 60 remain open when not energized. It can be seen that when the output socket is successfully connected to the presentation device via the external cable, the contactor establishes a connection with the phase line connected to the output socket. Therefore, only when all output sockets in the power supply module are successfully connected to the performance equipment, all contactors in the loop control respective contacts to be closed under the power-on condition, and meanwhile, the positive connecting end 61 is also connected with the corresponding phase line, so that the loop is conducted, and the accuracy of confirming the wiring condition of the power supply module is ensured.
Still further, a protection resistor 63 is connected in series on the branch, and a protection resistor 63 is connected in series between the positive connecting end 61 and the contactor 60. The protection resistor 63 is used for limiting the loop current and/or the branch current, and the problem that the contactor is damaged due to overlarge current caused by directly connecting the phase line is solved.
As an optional embodiment, the power-on indication unit further includes a controller, a timer, and a normally closed switch (not shown) connected in series to the circuit; the timer is used for starting timing from the circuit conduction and controlling the normally closed switch to be switched off after the preset waiting time length is elapsed, and the controller is used for controlling the normally closed switch to be switched on when the circuit is switched off. It can be seen that the normally closed switch in the circuit is closed when the circuit is just turned on. The timer controls the normally closed switch to be switched off after the preset waiting time, so that the indicating lamp assembly can be lightened in the preset waiting time to prompt that the wiring of the power supply module is normal, and the indicating lamp assembly is extinguished after the preset waiting time, and unnecessary power consumption is reduced.
Further, as an optional implementation manner, the power supply module may further include a sound effect unit, where the sound effect unit is configured to send out a connection prompting sound effect when the loop is connected, so as to prompt that the connection of the power supply module is normal by matching with the indicator light assembly; and when the loop is disconnected, sending out a disconnection prompt sound effect to prompt that the connection of the power supply module is disconnected. Therefore, the light prompt of the indicator lamp assembly can be prevented from being ignored by constructors, and meanwhile, the sound effect unit is used for playing a sound prompt role.
The power supply module for professional performance disclosed by the embodiment of the utility model is described in detail, a specific example is applied to explain the principle and the implementation mode of the utility model, and the explanation of the above embodiment is only used for helping to understand the power supply system of the performance lamp and the core idea thereof; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, and in summary, the content of the present specification should not be understood as the limitation of the present invention.
