Abstract

The utility model relates to an insulating sheath used for replacing an electric energy meter. The insulating sheath is an insulating sleeve with an electric energy meter inlet hole at one end, and the inner cavity of the insulating sleeve matches the wire diameter of the electric energy meter inlet end. . When the electric energy meter is rotated, the bare copper core of the wire is covered with an insulating sheath, which can effectively avoid the short circuit between the three-phase incoming wires or between the three-phase incoming wire and the meter box, and also avoid electric shock accidents for the workers who install the meter and connect the electricity. , can improve the safety of meter installation and power connection.

Description

Insulating sheath for replacement of energy meters

technical field

The utility model relates to an insulating sheath used for replacing an electric energy meter. the

Background technique

Due to the limitation of the on-site environment, the horn insurance on the wall is not convenient for power outage operation. On the other hand, power companies need to increase supply, expand sales and provide high-quality services, while avoiding unnecessary losses to customers caused by power outages. Therefore, most of the replacement of electric energy meters They are all carried out under live conditions, and the size of the meter box is fixed, and the space inside is limited. Since the wires at the inlet end of the electric energy meter are exposed, it is easy to cause the following faults: First, A, B, C three-phase The second is the short circuit between the A, B, C three-phase incoming lines and the meter box; the third is that the staff who install the meter and connect to the electricity are prone to electric shock accidents. the

Contents of the invention

The purpose of this utility model is to provide an insulating sheath for replacing the electric energy meter, which can improve the safety of meter installation and connection to electricity, in view of the safety accidents such as short circuit and electric shock of the staff when replacing the electric energy meter when it is charged. the

In order to achieve the above purpose, the utility model adopts the following technical scheme: the insulating sheath is an insulating sleeve with an electric energy meter inlet hole at one end, and the inner cavity of the insulating sleeve matches the diameter of the wire at the electric energy meter inlet end. When rotating the electric energy meter, when removing one of the three-phase wires of A, B, and C, put an insulating sheath on the exposed copper core of the wire, and finally put an insulating sheath on the copper core of the zero line. Thereby avoiding the short circuit between the three-phase incoming wires, or the short circuit between the three-phase incoming line and the meter box, and also avoiding electric shock accidents for the staff who install the meter and connect the electricity. the

The depth of the inner cavity of the insulating sleeve should be greater than 7cm, so that the exposed copper core at the inlet end of the electric energy meter can be completely inserted into the sheath. the

It can be seen from the above technical scheme that the utility model adopts a special insulating sheath, and when the electric energy meter is rotated, the exposed copper core of the wire is covered with an insulating sheath in time, which can effectively avoid the three-phase incoming wires or the three-phase incoming wires and the meter. Short circuit between boxes can also avoid electric shock accidents for workers who install meters and connect to electricity, and can improve the safety of installing meters and connecting to electricity. the

Description of drawings

Fig. 1 is the structural representation of the utility model. the

Detailed ways

As shown in Fig. 1, the insulating sheath is an insulating sleeve 2 with an electrical energy meter inlet jack at one end, and the inner chamber 1 of the insulating sleeve 2 matches the wire diameter of the electrical energy meter inlet terminal. The depth of the inner cavity 1 of the insulating sleeve 2 is greater than 7cm. the

This insulating sheath can also be made on the installation site. The insulating sleeve 2 is made of the outermost insulating sheath of the cable, and an insulating tape is wound on one end of the insulating sheath to form an end cap 3 . the

Claims (2)

1. be used to change the insulating sleeve of electric energy meter, it is characterized in that: said insulating sleeve is the insulating sleeve (2) that an end has electric energy meter inlet wire jack, and the inner chamber of insulating sleeve (2) and electric energy meter end of incoming cables diameter of wire match.

2. the insulating sleeve that is used to change electric energy meter according to claim 1 is characterized in that: the inner chamber degree of depth of insulating sleeve (2) is greater than 7cm.
