Abstract
The utility model relates to an epoxy resin pouring insulator for an SF6 electric appliance, which comprises an insulator body. Two annular electrodes and an insert are poured inside the insulator body, the two annular electrodes are respectively positioned at two ends of the insulator body, the insert is a main conduction loop, and two ends of the insert are respectively connected with external tulip contacts. The epoxy resin pouring insulator has the advantages of simple structure, reliable operation and high practicality.
Description
Technical field
The utility model relates to ZF3-126 Cubicle Gas-Insulated Switchgear (hereinafter to be referred as GIS) field, specifically, is a kind of SF6 that optimized (claiming GIS again) electrical equipment poured with epoxy resin insulator.
Background technology
The SF6 gas insulated metal enclosed swit chgear claims GIS again, with its high voltage, big capacity, volume is little, failure rate is low and intelligently be widely used all over the world.Owing to be the insulating part that plays support and mechanical fixation effect between conducting system high potential parts and the earth potential shell in the SF6 High-Voltage Electrical Appliances; Also be the corresponding part of dynamic/static contact that connects in the High-Voltage Electrical Appliances between fracture, play the insulation supporting role.
Insulating part in the SF6 High-Voltage Electrical Appliances in the conducting system also will bear the effect of SF6 gas pressure separation in GIS electrical equipment; Short circuit current by the time bear the many-sided effect of SF6 electric arc analyte corrosive nature and electric power machinery performance; And as insulator self measurement of partial discharge.
Generally can not definitely measure the partial discharge of insulator inside when the poured with epoxy resin insulator carries out measurement of partial discharge in the existing SF6 High-Voltage Electrical Appliances, be the partial discharge of measuring insulator surface mostly, and measured value is not accurate enough.When carrying out charged detection, the SF6 High-Voltage Electrical Appliances generally all to adorn an electrode on the through hole on siphunculus, complex structure, inconvenience.
The utility model content
The utility model purpose is to provide a kind of SF6 electrical equipment poured with epoxy resin insulator of optimizing, and satisfies the requirement of the measurement of partial discharge of charged detection between conducting system high potential and the earth potential shell and insulator itself.
The utility model is achieved through the following technical solutions:
SF6 electrical equipment poured with epoxy resin insulator, comprise insulator body, described insulator body inside is watered and is adorned an annular electrode, an inserts, described annular electrode comprises two, two annular electrodes lay respectively at the two ends of described insulator body, described inserts is a main conductive circuit, and described inserts two ends connect extraneous Mume flower contact respectively.
The external on-line measuring device of described annular electrode.
The external Partial discharge detector of described annular electrode.
Operation principle of the present utility model is: produce induced voltage on the annular electrode when insulator charged, can judge that by external on-line measuring device whether conducting system is charged, guarantees safe operation of power system.To the casting quality of insulator self, connect Partial discharge detector on the other hand, measure the partial discharge phenomenon of insulator inside by annular electrode.
Beneficial effect: simple in structure, the reliable operation of the utility model, practical.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cross-sectional view of the utility model SF6 electrical equipment with the poured with epoxy resin insulator.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
Embodiment:
As shown in Figure 1, comprise epoxy resin 1, annular electrode 2, inserts 3 among the figure, utilize insulator when epoxy resin 1 cast, in mould, put into an annular electrode 2 and an inserts 3, the cast typing.Annular electrode 2 comprises two, and two annular electrodes lay respectively at the two ends of insulator body.Inserts 3 is a main conductive circuit, and inserts 3 two ends connect extraneous Mume flower contact respectively.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
