Anti-pollution three-phase electric energy meter and using method thereof

Abstract

The invention discloses an anti-pollution three-phase electric energy meter and a using method thereof. The device comprises an outer shell, a movable plate and an electric energy meter body, wherein fixing plates are fixedly arranged at the four corners of the outer side of the outer shell, and fixing holes are formed in the centers of the fixing plates. According to the invention, an operation block slides to enable a first limiting rod to be away from the inner position of a limiting groove, then the movable plate slides upwards to drive a transparent plate to move upwards, the outer shell can be opened, the opening work is conducted without hinge rotation, and gaps of the outer shell are reduced. Meanwhile a drying agent is used for drying the inner position of the outer shell through a third through hole, the installation position of the electric energy meter body is ensured to be dry. Meanwhile, a storage box can be pulled out towards the left side through a handle, shielding cloth is pulled open to shield the third through hole during pulling, the drying agent is convenient to replace, and the interior of the outer shell is prevented from being communicated with the outside through the third through hole during replacement, so that an independent closed drying space is formed in the outer shell, and the electric energy meter main body is prevented from being polluted during use.

Description

technical field [0001] The invention relates to the field of electric energy meter equipment, in particular to an anti-pollution three-phase electric energy meter and a use method thereof. Background technique [0002] A three-phase watt-hour meter is a watt-hour meter used to measure the electric energy output by a power supply (or consumed by a load) in a three-phase AC circuit. Its working principle is exactly the same as that of a single-phase watt-hour meter, except that it adopts multiple sets of driving components and multiple aluminum disks fixed on the rotating shaft in order to realize the measurement of three-phase electric energy. [0003] The three-phase watt-hour meter is suitable for measuring three-phase four-wire AC active energy with a rated frequency of 50Hz or 60Hz. For fixed installation and indoor use, it is suitable for the environment, and the air does not contain corrosive gases and avoids the influence of dust, mold, salt spray, condensation, insec...

AI Technical Summary

Problems solved by technology

[0005] 1. The existing three-phase electric energy meter has high installation requirements during use. It is afraid of being damaged by environmental pollution and reducing the service life. When used in a high-risk environment, it is necessary to use the cabinet for protection, and there is a gap in the hinge connection position of the cabinet. There are many, and it is necessary to open the reading observation of the three-phase electric energy meter, and the protection function is limited;

[0006] 2. The existing three-phase watt-hour meter needs to be 1.8 meters away from the ground when it is installed and used. At the same time, it is necessary to ensure that the three-phase watt-hour meter is in a vertical position, and the existing installation equipment cannot guarantee that the installed three-phase watt-hour meter is in a vertical position. , affecting the use of three-phase watt-hour meters;

[0007] 3. The existing three-phase watt-hour meter needs to be connected to the connection line when it is used, and a long connection line needs to be reserved for normal connection. Inconvenient, so a device is urgently needed to solve the above problems
