Abstract
The utility model relates to a three-phase four-wire multifunctional electric energy meter and comprises the electric energy meter and insulating pipes inserted into jacks of binding posts of the electric energy meter. Problems of short distance between the binding posts and easily-generated short circuit of the binding posts of the electric energy meter are resolved by applying insulating pipes to the binding posts of the electric energy meter. The three-phase four-wire multifunctional electric energy meter enhances local insulation of wires and reduces faults of short circuits between phases and grounding when equipment is in a long-time operation or overvoltage, protecting metering equipment.
Description
Technical field
The utility model relates to a kind of three-phase and four-line multifunctional electric energy meter.
Background technology
Present widely used three-phase and four-line connection box of electric energy meter phase spacing is near, when long-play, superpotential, causes phase fault easily, and metering outfit is burnt, and causes damage to the user.
The utility model content
The utility model technical matters to be solved provides and a kind ofly can effectively reduce faults such as phase fault, ground connection, the three-phase and four-line multifunctional electric energy meter of protection metering outfit.
The utility model adopts following technical scheme:
The utility model is made up of electric energy meter and the insulation tube that is inserted in the connection box of electric energy meter terminal jacks.
The good effect of the utility model is following:
The utility model connection box of electric energy meter terminal place installs insulation tube additional; Solved because the connection box of electric energy meter terminal distance closely, the problem that is short-circuited easily; The utility model is strengthened the minor insulation of lead; When equipment long-play or superpotential, reduced faults such as phase fault, ground connection, protected metering outfit.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
In the accompanying drawings: 1 electric energy meter, 2 connection terminal jacks, 3 insulation tubes, 4 gim pegs.
Embodiment
Shown in accompanying drawing 1, the utility model is by electric energy meter 1 and be inserted into that insulation tubes 3 constitute in the electric energy meter 1 connection terminal jack 2.
Use the utility model, the connection electric wire at connection terminal place is at first passed insulation tube 3, and then insert in the connection terminal jack 2 to fix and get final product through gim peg 4.
Connection terminal jack 2 places of the utility model electric energy meter 1 install insulation tube 3 additional; Solved because the connection box of electric energy meter terminal distance closely, the problem that is short-circuited easily; The utility model is strengthened the minor insulation of lead; When equipment long-play or superpotential, reduced faults such as phase fault, ground connection, protected metering outfit.
