Three-phase electricity meter provided with anti-misoperation mechanism and using method of three-phase electricity meter

Abstract

The invention discloses a three-phase electricity meter provided with anti-misoperation mechanism. The three-phase electricity meter comprises a shell and an electricity meter body, wherein the electricity meter body is located in an inner cavity of the shell, two sides of the electricity meter body are each provided with two installation mechanisms, the left side of the electricity meter body is provided with a knife switch, the knife switch is fixedly connected to a rear wall of the inner cavity of the shell, and the top of the knife switch is electrically connected with two first wires. According to the three-phase electricity meter, through the up-down movement of the movable plate, when the connection part of the second electric wire and the third electric wire of the ammeter body needs to be maintained, the movable plate shields the positions of the second electric wire and the third electric wire; when the electric meter body is overhauled, an operator only needs to pull an operation handle of the knife switch downwards to perform power-off operation, and then the movable plate is driven to move downwards, so the position for connecting the second electric wire and the third electric wire is displayed, the electric meter body is overhauled, safety of the overhauling operation is guaranteed, and misoperation of the operator during the overhauling operation is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a three-phase electric meter provided with an anti-misoperation mechanism and a method for using the same. Background technique [0002] In power equipment, many related equipment are needed, such as power distribution cabinets, ring network cabinets, power meters, air switches, etc. There are also many types of power equipment power meters, such as single-phase power meters, three-phase power meters, three-phase four-wire Ammeters, etc., among which three-phase ammeters are widely used. During use, three-phase ammeters are mainly used to record electricity consumption. When installing, just connect the incoming and outgoing wires to the electric meter. The existing three-phase electricity meters have certain potential safety hazards when performing the above operations, and the power supply wires have not been cut off. switch, in order to ensure the safety of the m...

[0002] In power equipment, many related equipment are needed, such as power distribution cabinets, ring network cabinets, power meters, air switches, etc. There are also many types of power equipment power meters, such as single-phase power meters, three-phase power meters, three-phase four-wire Ammeters, etc., among which three-phase ammeters are widely used. During use, three-phase ammeters are mainly used to record electricity consumption. When installing, just connect the incoming and outgoing wires to the electric meter. The existing three-phase electricity meters have certain potential safety hazards when performing the above operations, and the power supply wires have not been cut off. switch, in order to ensure the safety of the meter connection operation. However, some electric maintenance construction workers will not cut off the power-in circuit because of trouble, which is prone to unnecessary safety hazards. With the development of technology, people often Will not be satisfied with the preparation of existing devices, and improve on the basis of existing devices, for this reason we bring a three-phase electric meter with an anti-misoperation mechanism and its use method
