The invention relates to an electrode and a molten salt electrolysis device. The electrode comprises a rod-shaped part and a supporting part, wherein one end of the rod-shaped part is fixedly connected with the supporting part; the rod-shaped part is positioned in an electrolytic bath while the supporting part is positioned at the outer side of the electrolytic bath and used for sealing an opening of the electrolytic bath during an electrolytic process; and the supporting part is electrically connected with an additional power supply. The electrode is very short, the electrode does not need to pass through the top end of an upper cavity to come into contact with the air in the process that the electrode enters or exits from the electrolytic bath, so that the lifting of the electrode in the upper cavity is realized. Thus, the electrode cannot be corroded, namely, the service life of the electrode is prolonged. The invention provides the molten salt electrolysis device which comprises the electrode and a wiring part. The supporting part is connected with the additional power supply through the wiring part, so that the effects of easy separation and proper movements between the additional power supply and the electrode are realized.

The invention discloses a smart electricity meter and an electricity theft prevention system. In the smart electricity meter, an electricity collection module is directly connected to the power supply output end of the electricity meter, and is used to collect the electricity consumption of all household appliances. The judgment module judges whether the electricity consumption measured by the watt-hour meter is consistent with the electricity consumption collected by the electricity consumption acquisition module. When the control module sends a control command to the power supply network center, the power supply network center cuts off the power supply to the watt-hour meter, thereby making the watt-hour meter stop supplying power to the household appliances. In the above manner, the present invention can effectively prevent the behavior of stealing electricity and reduce the hidden danger of electricity consumption.
