Abstract
The invention discloses a kind of orientable transformer secondary terminals protective cover, it is characterized in that: including: transformer body and for covering the protective cover (1) of secondary terminals on described transformer body, it is provided with for the circular hole (2) through screw on described protective cover (1), the inner surface of described protective cover (1) is provided with groove (3), be provided with on described transformer body with described groove (3) with the use of locating dowel, described protective cover (1) is additionally provided with explosion-protection equipment (4).The one orientable transformer secondary terminals protective cover that the present invention provides, has rainwater-proof, the function such as dust-proof, anti-electricity-theft, explosion-proof, and simple in construction, and reasonable in design, suit large area to popularize application.
Description
Technical field
The present invention relates to a kind of orientable transformer secondary terminals protective cover, particularly relating to one can position, and installs quick transformer secondary terminals protective cover.
Background technology
Secondary wiring terminals of transformers is after installing protective cover additional, it is possible to effectively protected, and prevents artificial short-circuited terminal or loosening binding post from carrying out electricity filching behavior；Meanwhile, after application protective cover, dust will not cover terminal, it is to avoid because dust makes moist the metering negative error causing short circuit two wire connecting terminal of transformer and cause, it is ensured that metering accuracy.
Current terminal cover exists and adds sealing inconvenience, screw is fixing after needing guiding through the screw on the hole of terminal cover and transformer, and owing to the screw on the hole of terminal cover and transformer is not at one, therefore screw perforation location is inaccurate, need to repeatedly adjust and could bore a hole successfully, lose time.
Also have, current terminal cover is general without explosion prevention function, and transformer once secondary circuit short-circuit, the biggest short circuit current certainly will be caused at secondary side, transformer explosion can be caused to burn, the existing transformer without explosion prevention function cannot be discharged at explosion time, the gases at high pressure of generation, easily causes more dangerous secondary injury.
Summary of the invention
The technical problem to be solved is to provide one and can position, and installs quick transformer secondary terminals protective cover；Further, the present invention provides a kind of transformer secondary terminals protective cover with explosion prevention function.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of orientable transformer secondary terminals protective cover, it is characterized in that: including: transformer body and for covering the protective cover of secondary terminals on described transformer body, it is provided with on described protective cover for the circular hole through screw, the inner surface of described protective cover is provided with groove, it is provided with the locating dowel used with described groove fit on described transformer body, described protective cover is additionally provided with explosion-protection equipment.
Described groove is identical with the shape of locating dowel and all includes triangle, rhombus, trapezoidal or unsetting.
Described explosion-protection equipment is one-way cock.
The offside door including mutually overlapping 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, described offside door has, with the couple positioned opposite of described offside door, the second horizontal projection being overlapped on above described first horizontal projection, and described offside door is movably set on described protective cover.
It is fixed by snap with described protective cover away from one end of described second horizontal projection that described activity is set to described offside door.
The outer surface of described one-way cock is provided with the protecting film for rainwater-proof.
The side of described protective cover is additionally provided with wire lead slot.
Described screw is socket cap strap sealing of hole screw.
The one orientable transformer secondary terminals protective cover that the present invention provides, groove and the setting of locating dowel, conveniently position protective cover to transformer body, behind location, circular hole is corresponding with the screwhole position on transformer body, only screw need to sequentially pass through circular hole and screw；The setting of explosion-protection equipment, it is achieved that the discharge of the gases at high pressure produced when transformer secondary terminals breaks down, does not haves gases at high pressure and can not discharge the subsequent explosion that protective cover causes.The one orientable transformer secondary terminals protective cover that the present invention provides, has rainwater-proof, the function such as dust-proof, anti-electricity-theft, explosion-proof, and simple in construction, and reasonable in design, suit large area to popularize application.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of explosion-protection equipment in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
As shown in Figure 1 and 2, a kind of orientable transformer secondary terminals protective cover, it is characterized in that: including: transformer body and for covering the protective cover 1 of secondary terminals on described transformer body, it is provided with on described protective cover 1 for the circular hole 2 through screw, the inner surface of described protective cover 1 is provided with groove 3, be provided with on described transformer body with described groove 3 with the use of locating dowel, described protective cover 1 is additionally provided with explosion-protection equipment 4.
Described groove 3 is identical with the shape of locating dowel and all includes triangle, rhombus, trapezoidal or unsetting.
Described explosion-protection equipment 4 is one-way cock.
The offside door 5 including mutually overlapping of described one-way cock and offside door 6, described offside door 6 is fixed on described protective cover 1 and the couple positioned opposite of described offside door 6 and described offside door 5 has the first horizontal projection 7, described offside door 5 and the couple positioned opposite of described offside door 6 have the second horizontal projection 8 being overlapped on described first horizontal projection 7 above, and described offside door 5 is movably set on described protective cover 1.
It is fixed by snap with described protective cover 1 away from one end of described second horizontal projection 8 that described activity is set to described offside door 5.
The outer surface of described one-way cock is provided with the protecting film for rainwater-proof.
The side of described protective cover 1 is additionally provided with wire lead slot 9.
Described screw is socket cap strap sealing of hole screw.
The above is only the preferred embodiment of the present invention; it is noted that, for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
