Abstract
The present utility model discloses an outdoor knife switch anti-rain cover for transformer substation, comprising a parachute skirt with a downward concave and a cannula with a via hole opened therein is displaced upright to pass through top center of the parachute skirt which are fixed and connected integrally into a whole. Flutes are set circling the tube wall of the outer tube wall at the upper and lower end parts of the cannula, and fastening clips are set inside the flutes. The present utility model, having a reasonable design and a simple structure, has excellent effect of keeping rain water out, and is installed and maintained conveniently.
Description
Technical field
The utility model relates to a kind of rain insensitive device of power transmission and transformation outdoor power equipment, the outdoor disconnecting link rain cover of particularly a kind of transformer station.
Background technology
At present, many serious problems that powered operation administrative department causes because of rainwater the outdoor disconnecting link of transformer station, some that take are such as with the Polypropylence Sheet wrapping, with interim measures such as sheet rubber block, not from long-range and fundamentally deal with problems.This type of problem not only causes the outdoor switch operation rotation axis of transformer station and the corrosion of disconnecting link locking lockset serious, even because of the suitable disconnecting link drive link infiltration of rainwater disconnecting link auxiliary switch, cause that DC ground fault takes place again and again in the transformer station, directly reliable the and safety of influence power supply.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provide a kind of simple in structure, rain cover is effective and the installation and maintenance outdoor disconnecting link rain cover of transformer station easily.
The technical solution of the utility model is: the outdoor disconnecting link rain cover of a kind of transformer station, it is characterized in that: it comprises the full skirt 3 that concave surface is provided with down, pass full skirt 3 top center and vertically be provided with the sleeve pipe 1 that has through hole 2 in it, sleeve pipe 1 and cluster parachute 3 are connected to one, the tube wall circumference is equipped with groove 4 in the outer tube wall upper edge of sleeve pipe 1 upper end and bottom, is provided with fastening card 5 in the groove 4.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, and is simple in structure, and rain cover is effective, and installation and maintenance are convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises the full skirt 3 that concave surface is provided with down, pass full skirt 3 top center and vertically be provided with the sleeve pipe 1 that has through hole 2 in it, sleeve pipe 1 and full skirt 3 are connected to one, the tube wall circumference is equipped with groove 4 in the outer tube wall upper edge of sleeve pipe 1 upper end and bottom, is provided with fastening card 5 in the groove 4.In addition, for increasing the structural strength of full skirt 3, on the concave surface of full skirt 3, radially be provided with 6 reinforcements 6; Described sleeve pipe 1, full skirt 3 and reinforcement 6 are by elastomeric material integrated poured compression moulding in mould.
When the utility model uses at the scene, sleeve pipe 1 is enclosed within on the drive link of disconnecting link auxiliary switch top by the through hole on the sleeve pipe 12, after the position of sleeve pipe 1 is determined, tightens the fastening card 5 in the groove 4, the utility model can be fixed on the drive link, play effects such as rain cover, dust.
