Abstract

The invention provides an anti-static-interference electric power metering device. The device comprises a box body, an insulating layer, a box door, a metering unit, a shielding cover, a heat dissipation fan, a junction box, a display screen and a separation plate. A front end of the box body is provided with the box door. An inner surface of the box body is provided with the insulating layer. The separation plate is transversely arranged at a middle position of the box body. An internal portion of the box body is provided with the metering unit which is located above the separation plate. An external portion of the metering unit is provided with the shielding cover. The heat dissipation fan is arranged on a left-side upper portion of the box body. The junction box is arranged below the separation plate. Through arranging the metering unit, the shielding cover, the insulating layer and the junction box, a stray current in a line can be cut off, static shielding is provided for a metering single chip microcomputer and direct discharge interference generated by an electrostatic charged body to an instrument can be avoided. An anti-interference capability of the metering single chip microcomputer is increased and static electricity is not generated in the box so that an anti-static and anti-electromagnetic-interference capability of the metering device is improved.

Description

technical field [0001] The invention relates to the technical field of electric power metering devices, in particular to an anti-static interference electric power metering device. Background technique [0002] At present, the structure design of the existing power metering device is unreasonable, and the main disadvantages are as follows: 1. The loss of the meter is high; 2. If the staff is not careful enough to check the three phases of A, B, and C, it is easy to cause wrong wiring of the metering circuit and affect the power. The department charges normally; 3. There are ventilation holes on the box body, which are easy to enter water and corrode the inner parts of the box; 4. The inner parts of the box are easy to be affected by moisture, which will affect the use. [0003] With people's understanding of static electricity, static electricity will cause direct discharge interference to the instrument, and the discharge in the air will also interfere with the meter. The p...
