Abstract
The utility model discloses a sealing gasket protection type transformer porcelain bushing structure, which comprises a box cover, a high-voltage porcelain bushing and a low-voltage upper porcelain bushing which are arranged above the box cover, and a low-voltage lower porcelain bushing which is arranged below the box cover, wherein annular limiting grooves are upwards formed in a joint of the high-voltage porcelain bushing and the top of the box cover, and sealing gaskets are embedded in the limiting grooves; and annular limiting grooves are upwards formed in a joint of the lower-voltage upper porcelain bushing and the top of the box cover, and sealing gaskets are embedded in the limiting grooves. The sealing gasket protection type transformer porcelain bushing structure is safe and reliable in sealing performance, ultraviolet-resistant and weathering-resistant, the sealing gaskets are inlaid in the porcelain bushing, the phenomenon that oil is leaked due to ageing of the sealing gaskets is avoided, and the characteristics that the high/low-voltage porcelain bushings are safely protected and are leakage-free are realized.
Description
Technical field
The utility model relates to a kind of porcelain shell for transformer tubular construction.
Background technology
The present used porcelain bushing of domestic existing oil-filled transformer adopts Shen always and becomes designed drawing, and there are the following problems in actual use:
1, the high and low pressure porcelain bushing is a plane at the case lid upper part, does not have stopper slot, easily puts partially when seal washer is placed, and causes press-fiting complete rear sleeve leakage of oil;
2, oil-filled transformer most be installed in outdoor, the high and low pressure sleeve pipe is exposed outside, seal washer exposes equally in air, seal washer can be aging very soon through ultraviolet ray irradiation (especially ultraviolet more intense west area) and long-term weathering, chaps, high and low pressure sleeve pipe seepage can occur when serious, bring product manpower and materials cost to increase, and affect company's product quality, affect equally the market of company.
Summary of the invention
The problems referred to above that exist for solving existing oil-filled transformer porcelain bushing, the utility model provides a kind of seal protection type porcelain shell for transformer tubular construction, its technical scheme of taking is: this structure comprises case lid, be located at porcelain bushing on the high voltage porcelain bushing pipe of case lid top and the low pressure and be located at porcelain bushing under the low pressure of case lid below, and the part that the high voltage porcelain bushing pipe is connected with the case lid end face upwards has annular spacing groove
, stopper slot
Be embedded with seal washer
, the part that porcelain bushing is connected with the case lid end face on the low pressure simultaneously upwards has annular spacing groove
, stopper slot
Be embedded with seal washer
The utility model increases transformer porcelain sleeve again mold the sealing stopper slot at high and low porcelain bushing and junction, case lid top, and prepares corresponding seal washer according to the size of stopper slot and the decrement of seal washer; When being installed in the high and low pressure sleeve pipe on the case lid, seal washer is because of the limited location groove, can not put partially inclined to one side with pressure, simultaneously after the seal washer compression puts in place, do not have seal washer and expose phenomenon, can be because of ultraviolet ray irradiation and wind and weather behind the product mounted outdoor, make seal washer aging, thereby stopped transformer at sleeve pipe installation place leakage of oil, greatly reduce oil-filled transformer leakage of oil rate, reduced the after-sale service expense, reduced product cost, when having improved product quality, the competitiveness of product in market has also improved.
The utility model mainly is applicable to oil-filled transformer high and low pressure porcelain bushing; Suitable place especially is the heavier places of environment for use damage ratio such as the more intense outdoor installation product of ultraviolet ray, and chemical plant.The utility model sealing property is safe and reliable, and seal washer is embedded in the porcelain bushing, and antiultraviolet, efflorescence prevention are stopped to bring the product leakage of oil because seal washer is aging, have realized the characteristics of transformer high and low pressure porcelain bushing security protection ne-leakage.
Description of drawings
Fig. 1 is the structural representation of the utility model high voltage porcelain bushing pipe;
Fig. 2 is the structural representation of the utility model low pressure porcelain bushing;
Fig. 3 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises case lid 1, be located at porcelain bushing 4 on the high voltage porcelain bushing pipe 2 of case lid 1 top and the low pressure and be located at porcelain bushing 5 under the low pressure of case lid 1 below, and high voltage porcelain bushing pipe 2 upwards has annular spacing groove with the part that case lid 1 end face is connected
7, seal washer
3 are embedded in stopper slot
In 7, porcelain bushing 4 upwards has annular spacing groove with the part that case lid 1 end face is connected on the low pressure simultaneously
8, seal washer
6 are embedded in stopper slot
In 8.
During assembling first with seal washer
3 and seal washer
6 are installed in respectively the stopper slot of porcelain bushing 4 on high voltage porcelain bushing pipe 2 and the low pressure
7 and stopper slot
In 8, then respectively on high voltage porcelain bushing pipe 2, the low pressure under porcelain bushing 4 and the low pressure porcelain bushing 5 be installed on the case lid 1, and upper bolt, fastening nuts put in place, on its mesolow under porcelain bushing 4 and the low pressure porcelain bushing 5 be fixed on corresponding position, last seal washer
3 and seal washer
6 compressions put in place and get final product.
