Abstract
This utility model relates to a protective casing for epoxy resincast dry voltage transformer high voltage loop tapping-off area with a protective casing corresponds to a boss and a tapping-off terminal of theactive casing accord with the length and width of a tapping-off terminal. The depth of the protective casing is determined according to the tapping-off terminal of the boss in the voltage transformer high voltage loop, and holes corresponding to the tapping-off terminal position are provided at the bottom of the protective casing. Plastic bolts connect with an interior flight of the tapping-off terminal through bottom holes of the protective casing. This utility model has the advantages that the protective casing adds a protective measure to the originally exposed tapping-off area, thereby greatly promoting safety and reliability of the voltage transformer operation.
Description
Technical field
The utility model relates to a kind of protective cover that is used for epoxy cast dry transformer high-tension coil tap region.Belong to the transformer technology field.
Background technology
At present, electric power system is to satisfy the requirement of user to the quality of power supply, for general distribution for power transformer, the off circuit tap changing transfor mers that adopt more, according to every day the electric weight peak valley change caused voltage fluctuation, change the effective turn of tap gear with Transformer Winding, thereby reach the purpose that changes no-load voltage ratio and transformer output voltage, to obtain the suitable voltage of low-voltage customer, guarantee the normal operation of electric equipment, but present for the tap region of transformer, all be to expose outside transformer, lack necessary protection, in the certain hidden danger of transformer existence in service.
Summary of the invention
The utility model is at the hidden danger of above-mentioned transformer existence in service, increase protective cover for the transformer tap region, making epoxy cast dry transformer coil tap region is that the tap joint position of live part and the external world have a well isolated effect, thereby improved the degree of protection of its live part, can effectively prevent to influence the safe operation of transformer because of falling into of foreign matter.
Technical solution of the present utility model: its structure is that boss, the tap of protective cover 1 and transformer high-voltage coil is corresponding, the shape of protective cover is square groove shape, the degree of depth of protective cover is determined that by the height of tap on the boss of transformer high-voltage coil the length and width degree of protective cover is consistent with tap length and width degree.Have and the corresponding hole of tap joint position in the bottom of protective cover, plastic bolt passes the base apertures of protective cover, is connected with the internal thread of tap.
Advantage of the present utility model: protective cover increases safeguard measure one can for exposed originally tap region, thereby has improved the fail safe and the reliability of transformer operation greatly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
In the accompanying drawing 1 is protective cover.
The contrast accompanying drawing, its structure is that boss, the tap of protective cover 1 and transformer high-voltage coil is corresponding, the shape of protective cover is square groove shape, and the degree of depth of protective cover is determined that by the height of tap on the boss of transformer high-voltage coil the length and width degree of protective cover is consistent with tap length and width degree.Have and the corresponding hole of tap joint position in the bottom of protective cover, plastic bolt passes the base apertures of protective cover, is connected with the internal thread of tap.This protective cover material is a polymethyl methacrylate, by the mold injects moulding, this material cracking resistance is good, for the 7-18 of silex glass doubly, mechanical strength and toughness are greater than silex glass more than 10 times, have outstanding weather resisteant and resistance to ag(e)ing, under low temperature (50～-60 ℃) and higher temperature (100 ℃), impact strength is constant, the excellent electric insulating energy is arranged, good thermoplastic processability is easy to machine-shaping, stable chemical performance.Material is 30% glass fiber reinforced nylon 6, requires heat distortion temperature more than 180 ℃.
