Abstract
The invention discloses a voltage wired copper-aluminum wiring clamp of an electric meter provided with a current transformer, and is characterized in that a U-shaped copper-aluminum upper plate and a U-shaped aluminum lower plate are fixed on a break open point in a primary wire insulation skin (2 cm) penetrating through the current transformer through screws, one end of a copper conductor of 4 mm<2> is soldered on the copper end of a copper-aluminum V-shaped plate (or is fixed on the copper end of the U-shaped plate through the screw), the other end of the copper conductor of 4 mm<2> is in compression joint with a voltage wired hole of the electric meter, and then is fastened by a prepared disposable insulation sealing box to complete operation.
Description
Technical field
The present invention relates to the watt-hour meter voltage line copper al wiring wire clamp that the watt-hour meter metering field particularly relates to the belt current mutual inductor.
Background technology
At present; Power distribution station big load user adopts the low meter mode of low confession to carry out the watt-hour meter metering; For its WT-MSR of strengthening management must be installed in the special-purpose table case (cabinet); Usually the watt-hour meter voltage line must be directly shown the interior main traverse line of case and is connected with penetrating, and lead common method of the pressure-wire of belt current mutual inductor three-phase and four-line watt-hour meter and power supply is to use 4mm so
2The plastics copper cash directly is wrapped on the aluminum steel; Consequently be difficult for tightly wrapping, and the copper aluminum conductor directly links to each other and be prone to the oxidation loose contact and cause the watt-hour meter short of electricity to press to make metering inaccurate, copper aluminum conductor catalytic oxidation excessively can burn out main traverse line; Not only cause the metering electric charge loss; And leave accident potential, simultaneously, site operation is installed has certain difficulty.
This shows that the above-mentioned existing watt-hour meter voltage line mode of connection obviously exists inconvenience and potential safety hazard, and demands urgently further improving in structure and use.
Summary of the invention.
The fundamental purpose of a kind of watt-hour meter voltage line of the present invention copper al wiring wire clamp is; Overcome existing belt current mutual inductor three-phase wire watt-hour meter voltage line and be connected not tightly with main traverse line, copper aluminium connect to be prone to the inconvenient installation defective of oxidation, and a kind of novel voltage line copper al wiring folder is provided; Technical matters to be solved makes it can compress lead; Thereby can improve the accuracy of watt-hour meter metering, easy to operate, guarantee equipment operation safety and management.
To achieve these goals, the present invention adopts following technology to realize.
The watt-hour meter voltage line copper al wiring folder that the present invention proposes is by U type copper aluminium upper plate, following U type aluminium sheet, upper and lower plates forcing screw, 4mm
2Annealed copper wire, wire clamp insulator seal hamper is formed; Wherein: going up U type copper aluminium sheet is by the synthetic integral body of two sections moulds of copper aluminium, aluminium end crimping aluminum conductor, and the weldering of copper voltage lead termination is crimped on the copper end.
Compress in order to ensure lead, watt-hour meter voltage wiring copper aluminum steel folder of the present invention must be decided by a conductor cross-section, can be by φ 35-70 commonly used; φ 95-120; Several kinds of models such as φ 150-240, the isochrone clamping structure is small but excellent, and the soft copper pressure-wire meets length, the cross section meets technical standard.The insulation of envelope box, fastening manageability.

Embodiment
In order further to set forth the present invention is means and the effect that reaches the technology that predetermined goal of the invention takes; Below in conjunction with accompanying drawing and preferred embodiments; To the watt-hour meter voltage line copper al wiring clamp body embodiment that proposes according to the present invention, the architectural feature effect, specify as after.
Consult Fig. 1 the present invention than the belt current mutual inductor three-phase and four-line watt-hour meter voltage line wire clamp of instance mainly comprise up and down U template, forcing screw 1, go up U type copper aluminium sheet 2, U type aluminium sheet 3, multiply annealed copper wire 4, wire clamp insulator seal cartridge 5 are formed down.
Consult Figure of description 1; When three-phase and four-line watt-hour meter, current transformer are contained in panel box (cabinet) by regulation in; Connect the secondary current line on request; Break aluminum conductor insulation course (2cm) at a lead appropriate location respectively after putting on large-section lead of current transformer; Be fixed on copper aluminium U type upper plate 2 and U type lower aluminum sheet 3 with screw 1 then and break aluminum conductor place annealed copper wire 4 (finished product is in advance the 2 bronze medal end places of the annealed copper wire 4 one end solderings U type copper aluminium sheet fortunately) other end and directly be pressed in the corresponding watt-hour meter voltage line wiring hole, on the copper aluminium voltage wire clamp of using the insulator seal cartridge 5 that is equipped with to be fixed on then to have installed, prevent that phase fault and ground connection are so that strengthen management.
The charged mutual inductor three-phase and four-line watt-hour meter voltage line binding clip of consulting Fig. 2 preferred embodiments of the present invention comprises that mainly U template forcing screw 1, last U type copper aluminium sheet 2, following U type aluminium sheet 3, copper core 4, wire clamp insulator seal cartridge 5 are formed up and down.
Consult Figure of description 2; When three-phase and four-line watt-hour meter, current transformer are installed in panel box (cabinet) by regulation in; Connect the secondary current line on request; Put on behind heavy in section of current transformer respectively at a lead appropriate location strip off aluminum conductor insulation course (2cm), be fixed on copper aluminium U type upper plate 2 and U type lower aluminum sheet 3 to be pressed on screw 1 then and break the aluminum conductor place, copper conductor 4 one ends are carried out the O type and are pressed in U type copper aluminium sheet 2 bronze medal end places (carrying out during the erecting stage) with screw 1; The other end directly is pressed in the corresponding watt-hour meter voltage line wiring hole; On the copper aluminium voltage wire clamp of using the insulator seal cartridge 5 that is equipped with to be fixed on then to have installed, prevent phase fault and ground connection, so that strengthen management.
The above only is a preferred embodiments of the present invention, and other copper aluminum conductor is linked to each other, and the straight-through watt-hour meter zero line side copper aluminum steel line of three-phase and four-line etc. is suitable for.
