[0034] Detailed Implementation
[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0036] This utility model provides a multifunctional power distribution box, referring to... Figure 1 As shown, it includes: a 380V three-phase AC connector 101, a dual-trip circuit breaker 102, a double-contact emergency stop switch 103, a double-contact start switch 104, a normally open electromagnetic AC contactor 105, a 220V power socket, a 220V power interface 109, a 24V DC regulated power supply 110, a humidity sensor 111, an infrared sensor 112, a smart digital meter 113, a current sensor, a DC input / output adapter terminal, a LAN port 124, an M5 nickel-plated grounding post 125, and a chassis 126.
[0037] The 380V three-phase AC connector 101 serves as the input terminal. External 380V three-phase power passes through the 380V three-phase AC connector 101 and reaches the dual trip circuit breaker 102. The dual trip circuit breaker 102 is equivalent to a main switch for the equipment. Manually closing the dual trip circuit breaker 102 puts the equipment into a standby power-on state.
[0038] The three-phase current output from the duplex trip circuit breaker 102 flows to the normally open electromagnetic AC contactor 105, and then the 380V power is converted into three 220V circuits through wiring, namely 220V power sockets 106, 220V power sockets 107 and 220V power sockets 108.
[0039] Reference Figure 2As shown, the control terminal of the normally open electromagnetic AC contactor 105 is equipped with a double-contact emergency stop switch 103 and a double-contact start switch 104. The specific connection relationship is as follows: the two-phase power supply L1 and L2 at the input terminal of the normally open electromagnetic AC contactor 105, the double-contact emergency stop switch 103, the double-contact start switch 104, and the control coil of the main contacts of the normally open electromagnetic AC contactor 105 constitute a control circuit. The on / off state of the normally open electromagnetic AC contactor 105 is controlled by the double-contact emergency stop switch 103 and the double-contact start switch 104. When the normally open contact of the double-contact start switch 104 is closed, the control path is connected, the coil of the normally open electromagnetic AC contactor 105 is energized, the main contacts of the contactor are closed, the normally open electromagnetic AC contactor 105 is connected, the normally closed contact of the double-contact emergency stop switch 103 is opened, and the normally open electromagnetic AC contactor 105 is disconnected. A normally open electromagnetic AC contactor 105 controls whether AC 220V power sockets 106, 107, and 108 are energized. In a preferred embodiment, a normally open auxiliary contact of the contactor is also provided in the control circuit. The normally open auxiliary contact is connected in parallel with the double-contact start switch 104 to increase the fault tolerance of the system. A surge suppressor is connected in parallel across the control coil.
[0040] The 220V power interface 109 connects to an external 220V AC power supply, providing voltage input to the 24V DC regulated power supply 110. The output of the 24V DC regulated power supply 110 serves as the input to humidity sensor 111, infrared sensor 112, intelligent digital meter 113, first Hall current sensor 114, second Hall current sensor 115, third Hall current sensor 116, and fourth Hall current sensor 117. These sensors are connected to the intelligent digital meter 113. Humidity sensor 111 and infrared sensor 112 measure the temperature and humidity at the center of the multi-functional power distribution box. (Refer to...) Figure 3 As shown, the first Hall current sensor 114 measures the voltage and current of the first output terminal L1 of the normally open electromagnetic AC contactor 105, the second Hall current sensor 115 measures the voltage and current of the second output terminal L2 of the normally open electromagnetic AC contactor 105, the third Hall current sensor 116 measures the voltage and current of the third output terminal L3 of the normally open electromagnetic AC contactor 105, and the fourth Hall current sensor 117 measures the voltage and current of the neutral terminal N. The specific parameters are displayed on the intelligent digital meter 113.
[0041] Reference Figure 4As shown, the multi-functional power distribution box is equipped with multiple infrared sensors 112, all of which are powered by a 24V DC regulated power supply 110. The positive terminals of the infrared sensors 112 are connected to pins AI1 to AI6 on the circuit board, respectively, and the negative terminals of the infrared sensors 112 are connected in parallel to the COM2 terminal on the circuit board. The metallic shielding layer of each infrared sensor 112 is connected in parallel to the grounding post.
[0042] Reference Figure 5 As shown, the humidity sensor 111 is powered by a 24V DC regulated power supply 110, and the signal pins on the humidity sensor 111 are connected to the AI7 and AI8 pins on the circuit board.
[0043] LAN port 124 serves as the communication interface. M5 nickel-plated grounding post 125 is the grounding protection terminal for the standard 19-inch rackmount chassis 126, providing protective grounding; the equipment must be connected to earth during use. DC input adapter terminals 118, 119, and 120 are generally connected to the output terminals of analog power supplies or other power equipment. DC output adapter terminals 121, 122, and 123 serve as output terminals, connecting to the adapter terminals on the equipment's power supply side to achieve external power output.
