Abstract
The utility model belongs to the field of transformer manufacturing, and particularly discloses a transformer ascending base hand hole processed electrically. The transformer ascending base hand hole processed electrically comprises hand hole bodies formed in a casing pipe ascending base wall, and hand hole ascending bases are arranged on the hand hole bodies. The transformer ascending base hand hole processed electrically is characterized in that a plurality of fixing plates stretching towards an axis are welded on the inner wall of the hand hole ascending bases, holes are formed in the fixing plates, and baffles are connected to the fixing plates through threaded rods, wherein the sizes and the shapes of the baffles correspond to those of the hand hole bodies. The transformer ascending base hand hole processed electrically is simple in structure, convenient to operate and low in production cost. Edges and corners of the hand hole bodies are changed to planes or circular arc faces, improving effects of electric field distribution are obvious, insulating strength and safety reliability can be effectively improved, and the outline dimension of a transformer and the cost of the transformer are reduced.
Description
(1) technical field
The utility model belongs to transformer manufacture technology, particularly a kind of power transformer enclosure hand hole through electric processing.
(2) background technology
For service work easy for installation and in the future, power transformer enclosure all need perforate on the seat wall that raises near sleeve pipe afterbody voltage equalizing ball place, the size in hole generally needs to satisfy both hands at least and can stretch into the seat that raises and get at sleeve pipe afterbody voltage equalizing ball, lead-in wire and can operate, so the size in hole can not be too small.Because the hand hole edge is corner angle, under the equal conditions, power plant's intensity of wedge angle is 4 ~ 8 times of plane, therefore, for a sleeve pipe rising seat insulation system, voltage equalizing ball, lead-in wire are to the corner angle of a wall than bore edges in one's hands that raise, insulation margin is much bigger, and the hand hole edge is the weak environment of insulation.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provides a kind of and improves dielectric strength, improved the power transformer enclosure hand hole through electric processing that power plant distributes.
The utility model is achieved by the following technical solution:
A kind of power transformer enclosure hand hole through electric processing, be included in the hand hole of offering on the sleeve pipe rising seat wall, hand hole is provided with hand hole rising seat, it is characterized in that: weld several on the inwall of described hand hole rising seat and stretch to the fixed head in axle center, offer porose on the fixed head, the baffle plate corresponding with hand hole shape size is connected on the fixed head by screw rod, and screw rod is provided with inner nut and the outer nut that corresponding fixed head arranges.
The utility model is by increasing baffle plate at the hand hole place; corner angle with baffle plate protection hand hole edge; make sleeve pipe raise the seat wall as much as possible near plane or arc surface, effectively improve power plant and distribute, improve the dielectric strength at the weak link place of sleeve pipe rising seat insulation system.
More excellent scheme of the present utility model is:
Described baffle plate lateral surface is provided with handle, by the control to handle, is used for position and the angle of controllable register, guarantees that it is to the good sealing of hand hole.
Described hand hole rising seating face is provided with the cover plate of sealing hand hole, and cover plate is provided with handle.
The utility model is simple in structure, and is easy to operate, and production cost is low, hand hole edge corner angle are converted into plane or arc surface, it is obvious to improve the Electric Field Distribution effect, can effectively improve dielectric strength and security reliability, reduces transformer overall dimension and reduces the transformer cost.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 sleeve pipe rising seat, 2 hand holes rising seat, 3 fixed heads, 4 baffle plates, 5 screw rods, 6 inner nuts, 7 outer nuts, 8 handles, 9 cover plates.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment is included in the hand hole of offering on sleeve pipe rising seat 1 wall, hand hole is provided with hand hole rising seat 2, weld several on the inwall of described hand hole rising seat 2 and stretch to the fixed head 3 in axle center, offer porose on the fixed head 3, the baffle plate 4 corresponding with hand hole shape size is connected on the fixed head 3 by screw rod 5, and screw rod 5 is provided with inner nut 6 and the outer nut 7 that corresponding fixed head 3 arranges; Described baffle plate 4 lateral surfaces are provided with handle 8; Described hand hole rising seat 2 surfaces are provided with the cover plate 9 of sealing hand hole, and cover plate 9 is provided with handle 8.
Instantiation is as follows:
(1) the traditional sleeve pipe seat 1 that raises, its insulation weak spot is the lead-in wire bore edges edge and corner position in one's hands of cylinder center.
(2) traditional sleeve pipe raise seat 1 when opening hand hole and cutting the barrel steel plate carefulness cut neatly, slick and sly, the steel plate of cutting off protects and can not be out of shape, and does not do waste material and throws away.The baffle plate 4 that goes the wedge angle burr carefully to polish smooth to do next step uses.
(3) in several fixed heads 3 of hand hole rising seat 2 walls welding, perforate on the plate.
(4) top polishing is good baffle plate 4 is temporarily fixed on the sleeve pipe rising seat 1.The same as far as possible in the time of need guaranteeing baffle plate 4 position angles and not cut off when noting fixedly, baffle plate 4 is even, as far as possible little with sleeve pipe rising seat 1 parietal suture crack.
(5) raise the fixed head 3 position of opening welding screw rod of seat 2 to baffle plate 4 at corresponding hand hole, remove temporary fixed plate after welding and polish smooth.
Elder generation is equipped with an inner nut 6 at the screw rod 5 of baffle plate 4 when (6) using, allow screw rod 5 pass the fixed head of hand hole rising seat 2 then, twist an outer nut 7 more outside, make this hand hole baffle plate 4 keep becoming a plane with a high-voltage terminal rising seat wall by regulating these two nuts.
