Abstract
A voltage transformer power box with a safety device comprises a box body and a voltage transformer. An insulating porcelain insulator is arranged above the box body, a fuse is arranged in the porcelain insulator, one end of the fuse is connected with a conductive bush at the top end of the porcelain insulator, and the other end is connected with a spring arranged in the porcelain insulator and is connected with the voltage transformer inside the box body via a conducting wire. The voltage transformer power box with a safety device can effectively protect the voltage transformer, prevent the voltage transformer from being burnout, greatly reduce cost and increase economic benefit.
Description
Technical field
The utility model relates to a kind of voltage transformer power supply box, is the voltage transformer power supply box that has safeties specifically.
Background technology
Voltage transformer is the visual plant that carries out electric energy metrical and mechanical and electrical protection in the electric power system, and safe, the reliable and economical operation of its precision and reliability and electric power system is closely related.Along with development of electric power industry, the electrical power transmission system capacity constantly increases, and the working voltage grade is more and more higher, and these are using and protecting and proposed new requirement voltage transformer all.
At present, mostly that uses on the market is electromagnetic potential transformer and capacitance type potential transformer, is arranged in the power supply box mostly.Yet; no matter be the power supply box which kind of voltage transformer is used; they are mostly simple to be exactly a casing, can only isolated voltage transformer, and be very much simple with regard to structure; function singleness with regard to function; power supply box all can not effectively be protected voltage transformer, is particularly having under big operating voltage or the false voltage effect, and the voltage transformer in the power supply box is easy to just be burnt out; increase the maintenance cost and the replacement cost of voltage transformer, and caused the wasting of resources.
Summary of the invention
In order to solve above-mentioned technical barrier, the utility model provides a kind of power supply box of protecting voltage transformer device that has, and it can prevent effectively that big voltage or false voltage from burning out voltage transformer, economizes on resources.
The utility model is in order to solve above-mentioned technical barrier, the technical scheme that is adopted is: the voltage transformer power supply box that has safeties, comprise casing and voltage transformer, the top of casing is provided with porcelain insulator, be provided with protective tube in the porcelain insulator, one end of protective tube is connected with the conductive sleeve on porcelain insulator top, and the spring that is provided with in the other end and the porcelain insulator joins, and links to each other with voltage transformer in the casing by lead.
The junction silica gel sealing of described conductive sleeve and porcelain insulator.
The junction silica gel sealing of described porcelain insulator and casing.
The beneficial effects of the utility model are:
1, the protective tube that is provided with in the porcelain insulator has protective effect to voltage transformer, in case extra-high pressure or the automatic disconnection of false voltage protective tube occur, can effectively protect voltage transformer, prevents that voltage transformer from being burnt.
2, protective tube replacing with low cost is convenient, compares with the instrument transformer that maintenance or replacing burn out, and greatly reduces cost, has improved economic benefit.
