Abstract
The utility model belongs to the electronic equipment safety field, and concretely provides a safe and overpressure resistant three-phase electric energy meter which comprises a meter case; the inner of the meter case is a screening can and is in connection with pressure wires and null lines which are fixed to the meter case through a card. According to the utility model, the pressure wires and the null lines are gathered and are fixed through the card, which solves the overpressure resistant problem among the pressure wires, the null lines and electronic components. According to the utility model, a part for clamping lines, i.e., a card is provided to gather the pressure wires and the null lines in a card box. The pressure wires and the null lines are completely separated from the electronic components so as to play a role in safety protection.
Description
Technical field
The utility model belongs to electronic equipments safety field, specifically relates to the withstand voltage three-phase electric energy meter of a kind of safety.
Background technology
At present; intelligent electric energy meter is universal in China; but some problems are found in the process using in reality; the parts that there is no permanent haulage line of existing three-phase electric energy meter; pressure-wire confusion; and there is no basic high voltage protective, under special state, can cause the consequence of burning table, also may cause to a great extent the generation of security incident.
Utility model content
The technical problems to be solved in the utility model is to provide the withstand voltage three-phase electric energy meter of a kind of safety.
Content of the present utility model is to comprise watchcase, and described watchcase inside is radome, and described watchcase is internally connected with pressure-wire and zero line, and described pressure-wire and zero line are fixed on watchcase by fastener.
Described pressure-wire is fixed in wiring casing.
The beneficial effects of the utility model are that the utility model draws pressure-wire and zero line in, fixes by fastener, has solved the problem of withstand voltage between pressure-wire and zero line and electronic devices and components.The utility model is by providing the part of a card line, and namely fastener, brings pressure-wire and zero line and block in line box together, and pressure-wire of the present utility model and zero line and electronic devices and components are kept apart completely, play safeguard protection effect.
The utility model has solved the problem of the cabling confusion of the flexible cord of three-phase electric energy meter inside, and the utility model is by unified cabling, and described pressure-wire 4 is unified in the bottom of wiring casing, walks to the zero line place on right side of the present utility model and unifies outlet by right side.Every pressure-wire of the present utility model can come by colouring discrimination mutually, makes the pressure-wire of the utility model inside and zero line uniform, facilitates electric wire assembling.
