Single-phase electric energy meter live line connection device, it is made of electric energy meter box body and two firewire casings and two zero curve casings, firewire casing and zero curve casing pass through electric energy meter box body, two zero curve sleeve surfaces are oppositely arranged several ratchets, two firewire sleeve surfaces are oppositely arranged several ratchets, a pair of of ratchet is set respectively between two zero curve casings between two firewire casings, the rotating bar of each ratchet is pierced by electric energy meter box body upwards, and zero curve sleeve port and firewire sleeve port set insulating layer and insulation end cap respectively.Present invention firewire casing and zero curve casing with ratchet transmission of setting creatively in existing electric energy meter box body directly can carry out live line connection operation to single-phase electric energy meter without power-off, have the advantages that reasonable design, easy to operate and safe and reliable.
Description
Technical field
The present invention relates to electric power facility maintenance technology fields, and in particular to a kind of single-phase electric energy meter live line connection device.
Background technology
Single-phase electric energy meter is the instrument for measuring electric energy, when electric energy meter is accessed circuit-under-test, current coil and electricity
Just there is alternating current to flow through in crimping circle, the two alternating currents generate the magnetic flux of alternation in their iron core respectively；Alternation
Magnetic flux passes through aluminium dish, and vortex is induced in aluminium dish；Vortex is acted in magnetic field by power again, so as to which aluminium dish be made to obtain torque
（Active torque）And it rotates.The power of load consumption is bigger, bigger by the electric current of current coil, the vortex induced in aluminium dish
Also it is bigger, make the torque that aluminium dish rotates bigger, when aluminium dish rotates, drive counter, the electric energy consumed is indicated, this
It is exactly the simple procedure of electric energy meter work.
Single-phase electric energy meter is if desired for wiring at present, it is necessary to be powered off by professional, then carry out wiring operation again, not only take
When it is laborious, and the normal use of power consumer can be influenced, bring economic loss to user and bother.
Invention content
The present invention provides a kind of single-phase electric energy meter live line connection device, to solve single-phase electric energy meter of the existing technology
The problem of powering off time-consuming and laborious wiring and influence power consumer normal use.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of single-phase electric energy meter live line connection device is made of electric energy meter box body and two firewire casings and two zero curve casings,
Firewire casing and zero curve casing pass through electric energy meter box body, and two zero curve sleeve surfaces are oppositely arranged several ratchets, two firewire sets
Pipe surface is oppositely arranged several ratchets, sets a pair of of ratchet respectively between two firewire casings between two zero curve casings, often
The rotating bar of a ratchet is pierced by electric energy meter box body upwards, and zero curve sleeve port and firewire sleeve port set insulating layer and absolutely respectively
Acies cap.
The present invention operation principle be：When single-phase electric energy meter needs wiring, without power-off, it is only necessary to rotate electric energy meter box body
The rotating bar of top ratchet, ratchet drive zero curve casing ratchet or firewire casing ratchet, stretch out zero curve casing or firewire casing
Electric energy meter box body can realize the wiring operation to single-phase electric energy meter.
Present invention firewire casing and zero curve casing with ratchet transmission of setting creatively in existing electric energy meter box body,
Can live line connection operation directly be carried out to single-phase electric energy meter without power-off, there is reasonable design, easy to operate and safe and reliable
Advantage.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of apparatus of the present invention；
Fig. 2 is the schematic elevation view of apparatus of the present invention.
1 electric energy meter box body, 2 ratchets, 3 ratchets, 4 insulating layers, 5 insulation end caps in figure.
Specific embodiment
As depicted in figs. 1 and 2, a kind of single-phase electric energy meter live line connection device, by electric energy meter box body 1 and two firewire casings
It is formed with two zero curve casings, firewire casing and zero curve casing pass through electric energy meter box body 1, and two zero curve sleeve surfaces are oppositely arranged
Several ratchets 2, two firewire sleeve surfaces are oppositely arranged several ratchets 2, between two zero curve casings and two firewire casings it
Between a pair of of ratchet 3 is set respectively, the rotating bar of each ratchet 3 is pierced by electric energy meter box body 1, zero curve sleeve port and firewire set upwards
Pipe port sets insulating layer 4 and insulation end cap 5 respectively.
The present invention operation principle be：When single-phase electric energy meter needs wiring, without power-off, it is only necessary to rotate electric energy meter box body
The rotating bar of top ratchet, ratchet drive zero curve casing ratchet or firewire casing ratchet, stretch out zero curve casing or firewire casing
Electric energy meter box body can realize the wiring operation to single-phase electric energy meter.
