Abstract
The utility model discloses a kind of orientable instrument transformer secondary terminals protective cover, it is characterized in that: comprising: instrument transformer body and the protective cover (1) for covering the secondary terminals on described instrument transformer body, described protective cover (1) is provided with for the circular hole (2) through screw, the inner surface of described protective cover (1) is provided with groove (3), described instrument transformer body is provided with described groove (3) with the use of reference column, described protective cover (1) is also provided with explosion-protection equipment (4).The one that the utility model provides orientable instrument transformer secondary terminals protective cover, have rainwater-proof, the function such as dust-proof, anti-electricity-theft, explosion-proof, and structure is simple, reasonable in design, suit large area to popularize application.
Description
Technical field
The utility model relates to a kind of orientable instrument transformer secondary terminals protective cover, and particularly relating to one can locate, and installs instrument transformer secondary terminals protective cover fast.
Background technology
Secondary wiring terminals of transformers, after installing protective cover additional, can effectively be protected, and prevents artificial short-circuited terminal or loosening binding post from carrying out electricity filching behavior; Meanwhile, after application protective cover, dust can not cover terminal, avoids and causes short circuit two wire connecting terminal of transformer and the metering negative error that causes because dust makes moist, ensure metering accuracy.
Current terminal cover existence adds sealing inconvenience, screw need through fixing after the screw on the hole of terminal cover and instrument transformer, and because the screw on the hole of terminal cover and instrument transformer is not at a place, therefore screw perforation location is inaccurate, repeatedly need adjust and could bore a hole successfully, lose time.
Also have, current terminal cover is general without explosion prevention function, and instrument transformer is once secondary circuit short-circuit, very large short circuit current certainly will be caused at secondary side, transformer explosion can be caused to burn, the existing instrument transformer without explosion prevention function is at explosion time, and the gases at high pressure of generation cannot be discharged, and easily cause more dangerous secondary injury.
Utility model content
Technical problem to be solved in the utility model is, provides one to locate, and installs instrument transformer secondary terminals protective cover fast; Further, the utility model provides a kind of instrument transformer secondary terminals protective cover with explosion prevention function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of orientable instrument transformer secondary terminals protective cover, it is characterized in that: comprising: instrument transformer body and the protective cover for covering the secondary terminals on described instrument transformer body, described protective cover is provided with for the circular hole through screw, the inner surface of described protective cover is provided with groove, described instrument transformer body is provided with the reference column used with described groove fit, described protective cover is also provided with explosion-protection equipment.
Described groove is identical with the shape of reference column and include triangle, rhombus, trapezoidal or unsetting.
Described explosion-protection equipment is one-way cock.
The offside door comprising overlap joint mutually of described one-way cock and offside door, described offside door is fixed on described protective cover and the couple positioned opposite of described offside door and described offside door has the first horizontal projection, the couple positioned opposite of described offside door and described offside door has the second horizontal projection be overlapped on above described first horizontal projection, and described offside door is movably set on described protective cover.
Described activity be set to described offside door away from one end of described second horizontal projection and described protective cover fixed by snap.
The outer surface of described one-way cock is provided with the diaphragm for rainwater-proof.
The side of described protective cover is also provided with wire lead slot.
Described screw is socket cap strap sealing of hole screw.
The one that the utility model provides orientable instrument transformer secondary terminals protective cover, the setting of groove and reference column, is conveniently positioned on instrument transformer body by protective cover, behind location, circular hole is corresponding with the screwhole position on instrument transformer body, only need by screw successively through circular hole and screw; The setting of explosion-protection equipment, achieves the discharge of gases at high pressure produced when instrument transformer secondary terminals breaks down, the subsequent explosion that there will not be gases at high pressure can not discharge protective cover to cause.The one that the utility model provides orientable instrument transformer secondary terminals protective cover, have rainwater-proof, the function such as dust-proof, anti-electricity-theft, explosion-proof, and structure is simple, reasonable in design, suit large area to popularize application.
