It is further arranged to：The circumferentially distributed setting in axle center of the fastener around casing.
It is more smoothly solid by that can be realized between this kind setting casing and case lid by using above-mentioned technical proposal
It is fixed.
It is further arranged to：The one side that the fastener contradicts case lid is equipped with outwardly toothed surface.
By using above-mentioned technical proposal, the frictional force between fastener and case lid is increased by the setting of toothed surface, so that
Realize that casing is more preferable fixed on case lid.
It is further arranged to：The elastic component is the sealing ring for being sheathed on casing, and the case lid, which is equipped with, contradicts sealing ring
The bulge loop of lateral wall.
By using above-mentioned technical proposal, sealing ring material has good elastic telescopic deformation and leakproofness in itself,
The leakproofness between casing and case lid can be increased by the setting of sealing ring；And by the setting of bulge loop further increase case lid with
Contact area between sealing ring so that better seal effect can be reached between case lid and sealing ring.
It is further arranged to：The sealing ring lateral wall is equipped with the annular groove being embedded for bulge loop.
By using above-mentioned technical proposal, further increase the contact surface between sealing ring and case lid by the setting of annular groove
Product, so as to reach better seal effect.
It is further arranged to：The case lid is equipped with platform sling.
By using above-mentioned technical proposal, the setting of platform sling enables case lid to realize convenient be connected admittedly with lifting device
It is fixed, so as to more easily be transported to case lid.
It is further arranged to：The case lid is equipped with oil level indicator.
By using above-mentioned technical proposal, staff can be apparent from transformer by observing oil level indicator
Height of oil.
It is further arranged to：The case lid is equipped with mercurial thermometer.
By using above-mentioned technical proposal, transformation can be apparent from by the setting staff of mercurial thermometer
Temperature inside device.
In conclusion the utility model has the advantages that：Realize convenient installation between casing and case lid simultaneously
The leakproofness between case lid and casing is improved, the lifting for case lid is facilitated by the setting of platform sling.
