Abstract
The utility model relates to a flange type check window for fully embedded case type transformer substation. The flange type check window comprises a window case, a window cover and a connecting screw rod. The utility model is characterized in that the edge of the window case is provided with a flange casing. One inner circle of the flange casing is provided with two loops of concentric steel bars. A sealing band is arranged between the steel bars and above the flange casing so to circumscribe the two steel bars. The window cover is connected with the flange casing of the window case by connecting screw rod. When closed, the window cover is connected and fixed with the flange casing in flange type. The device uses such technologies as metal shell production and welding. The window case and the window cover are connected with each other in flange type, and the window case is welded with a round steel. A sealing band is arranged between the window case and the window cover to prevent water and moisture. The inner side of the window cover is welded with a travel switch frame which can control the travel switch. Agile switching mode simplifies repairer entering the transformer substation and conducting operation and reparation. As the window case and the window cover are made of metal material and painted by compound material, the utility model improves quality and rank of the product, promotes protection level of the case type transformer substation and satisfies requirements of water prevention and leakage prevention.
Description
One, technical field
The utility model belongs to the equipment for power transmission and distribution field, particularly a kind of box-type substation flange form access panel that buries entirely.
Two, background technology
Existing box-type substation access panel adopts bolt to connect, and this connected mode waterproof sealing poor-performing constitutes a latent danger to the safe operation of transformer station.
Three, summary of the invention
The utility model provides a kind of improved box-type substation flange form access panel that buries entirely at having problems in the prior art.
Technical solution of the present utility model is: a kind of box-type substation flange form access panel that buries entirely, comprise maintenance window frame, access panel lid and connecting screw rod, maintenance window frame periphery is provided with flange frame, the inboard circumferential edges of flange frame is provided with the concentric steel bar of two circles, accompany sealing strip between the steel bar, sealing strip is located on the flange frame and is circumscribed with two steel bars, and the access panel lid is connected by connecting screw rod with flange frame on overhauling window frame, is that flange form is connected and fixed when closing.
This device utilizes metal shell manufacturing and solder technology, and access panel lid and maintenance window frame adopt flange form to link, and maintenance window frame welding round steel has sealing strip between access panel lid and the maintenance window frame, and is waterproof and dampproof.Be furnished with brass padlock on the access panel, the equipment that can prevent suffers malicious sabotage.Face down bonding travel switch support in the access panel lid, the control travel switch, on-off mode can make things convenient for the maintainer to enter power station built-in function and maintenance flexibly, because access panel lid and maintenance window frame adopt metal material, are coated with composite material outward, have improved product quality and class, improved the degree of protection of box-type substation, reached waterproof, antiseep waits requirement.
