Detailed Description
The present invention will be further described with reference to the following detailed description.
Referring to fig. 1 to 3, a restart apparatus of a power distribution terminal includes a case 10, a circuit board 20, a network interface 30, a power interface 40, and the like. The housing 10 is made of plastic, and is provided with a network interface 30, a power interface 40, an indicator light and the like.
The network connection port is used for connecting to a network cable of a communication switch, and data receiving and transmitting with the dispatching master station side are completed through a communication network.
The power supply interface 40 is connected in series with at least one power supply loop of the power distribution terminal. For example, 4 power interfaces are arranged, four power distribution terminals can be connected, each group is provided with two wiring terminals, and under the normal condition, the two terminals are in a conduction state, namely, a power supply loop of the power distribution terminal is switched on, so that normal power supply is realized.
The circuit board 20 is fixed in the housing 10 by bolts 25, and the control module 21, the communication module 22, the relay set, the power module 24, and the like are provided on the circuit board 20. The power module 24 is connected to an external AC220V power source via an external power cord, and is connected to the control module 21 for supplying power to the circuit board 20.
