Embodiment approach

[0019] The subject of protection of the present invention and embodiment are as follows:

[0020] The electric energy meter secondary voltage line safety protection connection device provided by the present invention, such as Figures 1 to 4 As shown, it includes an upper connecting piece 3, a lower connecting piece 2, an upper fixing piece 4, a lower fixing piece 7, a protective cover, and crimping bolts 8. The protective cover includes an upper protective cover and a lower protective cover 6. The upper protective cover Both the cover and the lower protective cover 6 are hollow box structures with one side opening, and the opening sides of the two are butted to realize the connection of the protective outer cover.

[0021] Further, the bottom end of the lower protective cover 6 is provided with a voltage wire through hole 10 for providing a channel for the secondary voltage wire of the electric energy meter to enter the connection device, thereby realizing the connection.

Abstract

The invention provides an electric energy meter secondary voltage line safety protection connecting device, which comprises an upper connecting piece, a lower connecting piece, an upper fixation piece, a lower fixation piece, a protection outer cover and pressing bolts. The distance between the upper connecting piece and the lower connecting piece is adjusted by adjusting the pressing bolts, and furthermore, connection of an electric energy meter secondary voltage line is realized; and the connection end of the lower connecting piece is provided with a connection washer for realizing connection between the connecting device and a transformer low-voltage bus. The connecting device is simple in operation steps when realizing corresponding connection, and prevents causing damage to the electric energy meter secondary voltage line in the electric energy meter secondary voltage line pressing and connection process; and therefore, the effective life of connection between the electric energy meter secondary voltage line and the transformer low-voltage bus is prolonged.

Description

technical field [0001] The invention relates to the field of electric energy meter connection devices, in particular to an electric energy meter secondary voltage line safety protection connection device. Background technique [0002] In the high-supply and low-meter power supply system, the electric energy meter, as an instrument for measuring electric energy, is one of the basic instruments to realize the measurement of customer electricity consumption. All of them can be covered and sealed to ensure the safety of electricity use. However, the secondary voltage line of the electric energy meter and the low-voltage busbar of the transformer are directly crimped on the top of the DW switch or the switch with screws and are exposed outside. At present, there is no standard connection device to solve this problem. There are great security risks. Therefore, it has become a new idea to consider developing a safety protection connection device for solving the above problems. ...
