Description
Technical field
The present invention relates to high voltage electric equipment manufacturing technology field, especially a kind of gas insulated load switch Petersen coil.
Background technology
The current arc quenching method of gas insulated load switch has multiple, as arc extinguishing grid pieces arc quenching method, arc blow-out mode of calming the anger, revolves arc magnetic field arc quenching method.The arc quenching principle revolving arc magnetic field arc quenching method is that gas insulated load switch is when disjunction, adopt arc electrode that arc current is introduced Petersen coil, arc current orders about electric arc fast rotational in the magnetic field that Petersen coil produces, the electric arc rotated constantly contacts fresh insulating gas, discharge heat energy, be cooled very soon, when current over-zero, electric arc is extinguished.The Chinese invention patent " Petersen coil for gas isolated on-load switch " of patent No. ZL99801182.7, Chinese utility model patent " a kind of longitudinal magnetic field breath arc device and gas insulated load switch " two patents of patent No. ZL200920146965.6 all adopt the above-mentioned arc quenching principle revolving arc magnetic field arc quenching method.
The winding impedance of " Petersen coil for gas isolated on-load switch " described Petersen coil of patent No. ZL99801182.7 is between 50 to 5000 Ω, the electric current resulting through Petersen coil is less, the magnetic field intensity that Petersen coil produces diminishes, arc extinguishing ability also diminishes with magnetic field intensity, cannot adapt to the requirement that on-load switch cut-offs big current.Longitudinal magnetic field breath arc device described in the Chinese utility model patent " a kind of longitudinal magnetic field breath arc device and gas insulated load switch " of patent No. ZL200920146965.6, its winding loop resistance is between 15m Ω to 40m Ω, larger by the electric current of winding, the magnetic field intensity produced is large, and arc extinguishing ability is strong.But the copper ring fuse that the longitudinal magnetic field of this structure ceases arc device used needs to adopt larger-size copper material to process, and manufacturing cost is high; Leading arc sheet is in addition welded on copper ring fuse, exists to lead arc sheet because of welding effect difference and cause the caducous hidden danger of arc sheet, and soldering angle consistency is poor simultaneously, affects arc quenching effect.
Summary of the invention
The object of this invention is to provide a kind of gas insulated load switch Petersen coil, it is high that it can solve Petersen coil manufacturing cost, and lead arc sheet and easily come off, soldering angle consistency is poor, affects the problem of arc quenching effect.
In order to solve the problem, the technical solution used in the present invention is: this gas insulated load switch Petersen coil, comprise becket, winding, metal anchor ear and mounting bracket, the side of described becket is provided with leads arc sheet, the initiating terminal of described winding is electrically connected with described becket, the end of described winding is electrically connected with described metal anchor ear, described metal anchor ear is located at the outer surface of described winding, described metal anchor ear is provided with described mounting bracket, and this mounting bracket and described arc sheet of leading are in the same side; Described becket is fixed on plastic hoop, and the outer surface of this plastic hoop and described becket is wound with described winding.
In technique scheme, more specifically scheme can also be: described becket and described in lead arc sheet and adopt the metallic plate of 1-2 mm of thickness to be once stamped to form.
Further: described winding adopts the metal material of sectional area 1-4 square millimeter to form around coiling on the outer surface of described becket and described plastic hoop; Described winding is provided with a packing ring adopting insulating material to make with the side of described metallic rings contact on central axis direction.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention: becket is once stamped to form with the metal material of leading arc sheet employing thinner thickness, and processing cost is low; Owing to leading the part that arc sheet is becket, avoid leading the hidden danger that arc sheet welding quality causes coming off, ensure that the consistency of arc quenching effect simultaneously, strengthen the reliability of Petersen coil.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
The gas insulated load switch Petersen coil of Fig. 1, Fig. 2, Fig. 3, becket 1 sunk screw 7 is fastened on plastic hoop 2, (in the present embodiment, metal refers to brass); Winding 3 is wrapped on the outer surface of becket 1 and plastic hoop 2, the initiating terminal of winding 3 is electrically connected with becket 1; Metal anchor ear 4 is set on the outer surface of winding 3, and the end of winding 3 is electrically connected with metal anchor ear 4; The side of becket 1 is provided with leads arc sheet 1.1, becket 1 and lead arc sheet 1.1 and adopt the brass sheet of 1.5 mm of thickness to be once stamped to form; Mounting bracket 5 is weldingly fixed on metal anchor ear 4, mounting bracket 5 with lead arc sheet 1.1 in the same side.Winding 3 adopts the thin copper belt coiling of the enamel-cover brass wire of 1 millimeter or sectional area 3 square millimeters to form, and what adopt in the present embodiment is that the enamel-cover brass wire coiling of 1 millimeter forms; The number of turn of winding 3 is at 20-50 circle, and the present embodiment is 30 circles, and the resistance of winding 3 is not more than 100 milliohms, and the present embodiment is 60 milliohms; The side that winding 3 contacts with becket 1 on central axis direction is provided with a packing ring 6 adopting insulating material to make.
The each of gas insulated load switch has a fixed contact 9 and a moving contact 10 mutually, fixed contact 9 is fixed on bus-bar 11, upper bus-bar 11 is provided with a Petersen coil, the becket 1 of Petersen coil leads arc sheet 1.1 towards fixed contact 9, leads arc sheet 1.1 and realize being electrically connected with upper bus-bar 11 by becket 1, winding 3, metal anchor ear 4, mounting bracket 5.
During gas insulated load switch disjunction load current, electric arc is produced between moving contact 10 and fixed contact 9, when moving contact 10 moves across and leads below arc sheet 1.1, electric arc on fixed contact 9 is transferred to rapidly leads arc sheet 1.1, arc current flows through becket 1 this moment, winding 3, metal anchor ear 4, the supreme bus-bar 11 of mounting bracket 5, winding 3 produces magnetic field, when moving contact 10 moves to below becket 1, electric arc goes to becket 1 from leading arc sheet 1.1, the magnetic field of Petersen coil makes electric arc fast rotational, the electric arc rotated constantly contacts fresh insulating gas, discharge heat energy, be cooled very soon, when current over-zero, arc extinction.In on-load switch separating brake process, electric arc fast transfer on fixed contact 9 leads arc sheet 1.1, becket 1 to Petersen coil, reduce electric arc to burn fixed contact 9, moving contact 10 is when moving to below becket 1, magnetic field is ordered about electric arc and is rotated at the outer surface of cupular part of moving contact 10, reduces electric arc to the scaling loss of moving contact 10.
