Fig. 1 is a schematic diagram of a combination of a power transmission bus and a plug device according to an embodiment of the utility model. As shown in fig. 1, the first plug device 10 has a plurality of

plugs

11, 12, for example a power transmission plug 12 and a communication transmission plug 11. The first plugging device 10 can be installed from the ground direction towards the power transmission bus 20, and the power transmission plug 12 and the communication transmission plug 11 can extend into the power transmission slot and the communication slot on the corresponding transmission bus 20. The communication plug 11 of the first plug-in device 10 has at least one contact 111 which can be connected to a transmission bus for communication. Preferably, the first plugging device 10 has a communication module 31 or a functional module 32 therein, and the functional module 32 is, for example but not limited to, a power measurement, a temperature control or an alarm device, and the contact 111 can be connected to a communication interface of the communication module 31 or the functional module 32. In addition, when the plurality of first plug devices 10 are installed on the power transmission bus 20, signal transmission can be performed through a Daisy chain (Daisy chain) or other architecture to avoid collision.

Fig. 2 is a block diagram showing connection between a plug device and a communication module and between plug devices and function modules according to an embodiment of the present utility model. As shown in fig. 2, a plug-in device for a current bus bar comprises: a first plug-in device 10; the connection portion 40 and the second plug device 50 are connected in parallel with the first plug device 10 through the connection portion 40, and the second plug device 50 includes an ammeter extension unit 501. The first plug device 10 includes a communication module 31 and a functional module 32, and one or both of the communication module 31 and the functional module 32 may be disposed inside or outside the first plug device 10. In another embodiment, the electric meter expansion unit 501 may be separately disposed inside or outside the first plug device 10. The communication module 31 includes RS485, wired and wireless communication protocols, wherein RS485 is a standard for 2-wire, half-duplex, balanced transmission line multi-point communication, which is specified as an electrical characteristic belonging to the physical layer of the OSI model. Is a standard promulgated jointly by the Telecommunications Industry Association (TIA) and the Electronic Industry Alliance (EIA). Digital communication networks implementing this standard can efficiently communicate over long distances in an electronically noisy environment and are therefore suitable for use in an industrial environment. Whereas the wired and wireless communication protocols may be those established by RJ45 or IEEE commonly used today. The functional module 32 includes a temperature sensing unit 321, a warning module 322 and a humidity sensing unit 323. The temperature sensing unit 321 can measure the temperature change caused by the current in the first plugging device 10, so as to determine whether the current is too large to overheat the first plugging device 10, when the temperature sensing unit 321 determines that the current is too large to overheat the first plugging device 10, the temperature sensing unit 321 sends a signal to notify the warning module 322, and when the warning module 322 receives the signal from the temperature sensing unit 321, the warning module sends a warning message to the monitor to warn that the temperature in the first plugging device 10 is abnormal, and the first plugging device 10 needs to be immediately processed to avoid damage. The humidity sensing unit 323 can measure whether the humidity in the first plugging device 10 is too wet and whether the parts therein are soaked in water or too high due to external rainwater or other external factors, and once the humidity sensing unit 323 senses that the humidity in the first plugging device 10 is too wet and the parts therein are soaked in water or too high, the humidity sensing unit 323 can send a signal to inform the alarm module 322, and when the alarm module group 322 receives the signal from the humidity sensing unit 323, an alarm message is sent to a monitor to warn that the humidity in the first plugging device 10 is abnormal, so that the abnormal situation needs to be immediately processed. Fig. 3 shows a parallel connection of the plug device according to fig. 2 and a second plug device, in which in fig. 3 the first plug device 10 is connected in parallel to the second plug device 50 via the connection 40. Fig. 4 is a diagram showing a structure of an electric meter disposed in the second plugging device according to fig. 3, as shown in fig. 4, the second plugging device 50 includes an electric meter expansion unit 501, and the electric meter expansion unit 501 includes a current sensor, a voltage sensor and an electricity meter, or other sensors for sensing electric values and the like. As shown in fig. 3 and 4, in the present utility model, electricity can be led from the non-electricity meter to the electricity meter expansion unit and then to the plug-in device, but this requires power outage expansion. However, in another embodiment, the power consumption can be monitored in parallel, and the electric meter can be extended without power outage or replaced without power outage.

The utility model has the effects that the new ammeter plugging device can monitor or control the equipment end current without changing the old product to add a switch or an ammeter (a comparator), and secondly, the plugging device with the function of hot plug expansion ammeter can expand ammeter modules without power failure or replace ammeter modules without power failure.

In addition, the utility model can ensure that customers do not need to purchase the monitoring electric phenotype PIU newly, so that the original PIU can be directly expanded to add the ammeter expansion unit, thereby achieving the monitoring function.

The utility model has been described with respect to the above-described embodiments, however, the above-described embodiments are merely examples of practicing the utility model. It must be noted that the disclosed embodiments do not limit the scope of the utility model.
