Abstract
The utility model discloses a cone step seal electrical appliance insulated porcelain sleeve fixedly mounted in an oil tank, which comprises a porcelain sleeve main body (7), a porcelain gland (4) and a conducting rod (1) and is characterized in that the top end surface of the porcelain sleeve main body (7) is provided with a cone groove (6); the inside of the cone groove is provided with a cone sealing element (5) higher than the top end surface of the porcelain sleeve main body; the lower part of the porcelain sleeve main body is respectively provided with a lower groove (9) and an annular groove (14); the inside of the lower groove is provided with a sealing element (8); the inside of the annular groove is provided with a clamp spring (13); a metal installing flange (11) with a screw rod (12) is arranged in the annular groove; and the middle calathiform part of the metal installing flange is embedded in the annular groove. The utility model can achieve the effect that the porcelain sleeve main body and the electrical appliance box are in firm connection with each other in a tight sealing mode so as to realize to fix the porcelain sleeve in the box, changes the existing mode that the porcelain sleeve is fixedly arranged outside the box, improves the sealing effect and ageing resistance of the porcelain sleeve, saves precious metals and is beneficial for energy saving and emission reduction. The cone step seal electrical appliance insulated porcelain sleeve fixedly mounted in the oil tank not only has attractive and generous appearance, firm fixation and convenient operation, but also can reduce production cost, improve the insulating property and guarantee the safety operation of the power transformer and the power capacitor.
Description
Technical field
The utility model relates to various electrical apparatus insulation insulators, in particular for the conical step sealed type electrical apparatus insulation insulator on power transformer, the power capacitor.
Background technology
At present, the insulated porcelain sleeve that is used on the various electrical equipment of high-voltage connection and low pressure outlet has following point:
The one, insulator and conducting rod all adopt spherical rubber seal sealing, have in addition adopt silver-plated welded seal, sealing contact surface is not only little, and rubber parts exposes, and is long when service time, ageing of rubber, the elasticity deficiency, securing member is loosening, causes sealing not firm, produce the seepage of oil, particularly silver-plated welded seal, complex process not only, and consume a large amount of precious metal materials such as silver oxide, increase production cost, be unfavorable for energy-saving and emission-reduction;
The 2nd, the seal of spherical sealing is circular to be to contact with the porcelain gland that compresses, rather than face contact, the diameter of the endoporus of porcelain gland and conducting rod has certain tolerance in addition, when exerting pressure, because discontinuity can produce offset (in not advising), not only outward appearance is ugly, breaking often appears in the porcelain gland, and has a strong impact on sealing effectiveness;
The 3rd, insulator is connected with the electric appliance box lid, all adopt case external welding presser feet bolt, with the fixing means that clamps, also adopting of having is silver-plated with the direct method of welding of metal, and these methods need be welded a plurality of double-screw bolt or welding many places faces of weld of fixedly clamping on the electric appliance box lid, not only cause the temperature distortion of electric appliance box lid, and destroyed overall appearance, especially presser feet set bolt height and insulator subumbrella distance is very near, and the arcing discharge happens occasionally, and brings a lot of potential safety hazards for the operation of electrical equipment.
The utility model content
Problem at insulator existence in the above-mentioned prior art, the utility model provide in a kind of aesthetic in appearance, good airproof performance, the case connect, fixed, technology is simple, conical step sealed type electrical apparatus insulation insulator easy to operate, safe in utilization and with low cost.
The technical scheme that the technical problems to be solved in the utility model is taked is: described fuel tank internal fixation is installed conical step sealed type electrical apparatus insulation insulator and is comprised the insulator body, porcelain gland and conducting rod, on insulator body top end face, cone tank is set, in cone tank, be provided with the taper seal that exceeds insulator body top end face, be respectively equipped with low groove and cannelure in insulator body bottom, in low groove, be provided with seal, in cannelure, be provided with jump ring, the metal mounting flange of band screw rod is housed in cannelure, and the middle bowl-shaped portion of metal mounting flange is bumped in the cannelure.
In order to make insulator body top end face and porcelain gland lower surface can realize accurately location and raising sealing better, be provided with the upper groove that to insert the taper seal upper part in described porcelain gland lower surface.
The utility model is because insulator body and porcelain gland adopt conical seal sealing, increased the contact-making surface of seal and insulator body, the contact of changing the time is the face contact, in insulator body bottom low groove and cannelure are set respectively, in low groove, be provided with seal, seal places plane on the electric appliance box cover plate, the metal mounting flange of band screw rod is housed in cannelure, and in cannelure, put into jump ring, oppositely lean electric appliance box cover plate lower plane and the insulator body is moved to pressing down with screw rod by the metal mounting flange, reaching the insulator body firmly is connected with the electric appliance box cover plate for sealing, thereby realize that insulator at the case internal fixation, has changed existing case external fixation mounting means, improved insulator sealing effectiveness and ageing resistace, can save precious metal, help energy-saving and emission-reduction.This practicality had been newly both elegant in appearance, fixed, easy to operate, can reduce production costs again, improved insulation property, ensured the safe operation of power transformer and power capacitor.
