Problems solved by technology

The resistivity of metal oxides is much greater than that of pure metals, which leads to an increase in the resistance of the metal electrodes, which in turn causes the contact points between the wires and the metal electrodes to heat up and damage the meter

Embodiment 1

[0037] In this embodiment, a smart meter with anti-oxidation function is provided, including a meter body 100 and a protection device, the meter body 100 is provided with an electrode 103, and the electrode 103 is arranged inside the protection device, so that the electrode 103 is not exposed In the air, the risk of the electrode 103 being oxidized can be reduced.

[0038] see figure 1 , in this embodiment, the protection device includes a base body 101, the base body 101 is provided with a cavity, the side wall of the base body is provided with a hole for the electrode 103 to pass through, and the electrode 103 is located in the cavity after passing through the hole.

[0039] In order to enhance the protection effect, insulating oil 102 can also be arranged in the cavity, and the electrode 103 is placed in the insulating oil 102 after passing through the hole. The insulating oil 102 has a good isolation effect, so it can further prevent air from contacting the electrode 103,...

Embodiment 2

[0044] This embodiment provides another smart meter with an anti-oxidation function, which is a further improvement on the basis of Embodiment 1. On the basis of Embodiment 1, this embodiment also includes a cable locking mechanism, which is used to lock or loosen the connector of the cable and the electrode 103 . Using the cable locking mechanism, it has a better connection effect than screw connection.

[0045] Specifically, such as figure 2 As shown, in this embodiment, the cable locking mechanism includes an electric control assembly and a lock. When the electric control assembly is powered on, the lock is opened, and the cable connector can be contacted or separated from the electrode 103; when the electric control assembly is powered off, the lock The parts are closed, and the joint of the cable is locked with the electrode 103.

Abstract

The invention relates to an intelligent electric meter with an anti-oxidation function and an installation method thereof. The intelligent electric meter comprises a meter body, an electrode is arranged on the meter body, and the intelligent electric meter further comprises a protection device. The protection device comprises a base body, the base body is provided with a cavity, insulating oil is arranged in the cavity, and the electrode is located in the insulating oil. According to the intelligent electric meter, the protection device is additionally arranged, so that the electrode can be protected greatly, and oxidation caused by contact with air is avoided, and accordingly damage to the electric meter due to resistance increase caused by electrode oxidation can be avoided, and the service life of the electric meter is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric meters, in particular to a smart electric meter with anti-oxidation function and an installation method thereof. Background technique [0002] The electric meter is a meter used to measure the electricity consumption of the user, and the smart electric meter not only has the metering function, but also usually has various functions such as communication, interaction, and rate calculation, so it is widely used in residential households and enterprise users. In wet weather, the metal electrodes of the meter react with water and oxygen in the air, causing metal oxides to form between the metal electrodes and the wires. The resistivity of metal oxides is much greater than that of pure metals, which leads to an increase in the resistance of the metal electrodes, which in turn heats up the contact points between the wires and the metal electrodes and damages the meter. Therefore, it is of great signif...
