Abstract
The utility model relates to a wire column protective shield for transformers, comprising screw caps 1, an upper cap 2 and a lower cap 3. The upper cap 2 and the lower cap 3 are sheathed on a wire post 4, and the upper part is tightened by screw caps 1. Conducting wires 8 are connected with the wire post between the upper and the lower caps and extend from an opening 9 of protective shields, and lead sealing 12, 11 can be sealed between the protective shields of the two wire posts and between the screw cap and the upper cap. The utility model has simple structure, low cost and convenient installation and has the functions of electricity anti-theft and short circuit protecting, and the utility model can also avoid the abuses of oil leakage of a transformer, dangerous and inconvenient meter looking up in the prior art.
Description
The utility model provides a kind of electrical installation, promptly a kind of distribution transformer Wiring terminal protective cover.
Present distribution transformer is equipped with the high-low pressure binding post, and high tension terminal and high-voltage line join, and the wiring of low tension terminal is delivered to the user by summary table with electricity.Because these binding posts all are exposed on the end cap of transformer, thereby anti-electricity-theft poor-performing.Electricity filching person is as long as wiring and walk around summary table from the low tension terminal can reach the purpose of stealing.In addition, because distribution transformer is put in the open more than the field, exposed binding post not only can be the wind and weather corrosion, but also often climbs up by holding on to the generation short circuit accident because of birds and beasts.In order to address these problems, many measures have all been adopted in various places.Wherein, what relatively popularize is to cover in transformer terminal to connect an iron case, and low tension terminal is buckled in the case, also summary table is placed in the case simultaneously, again with the chamber door lead sealing.Though can address the above problem with this way, fixedly the iron case need adopt several attachment bolts of transformer end cap and transformer housing, and this can be owing to the irregular or not enough transformer oil impregnate that causes of manual fastening bolt dynamics.In addition, because summary table is located at transformer top, need ascend a height when tabling look-up, promptly inconvenience danger close is again got injured by a fall electric shock accidents and is happened occasionally, and need have the monitoring personnel to carry out when therefore tabling look-up.The inconvenience owing to table look-up, the staff often takes estimation approach to replace tabling look-up, thereby has reduced work quality.
The purpose of this utility model be development a kind of can be anti-electricity-theft, anti-short circuit, can not cause the transformer seepage, the Wiring terminal protector easily of tabling look-up.
Technical scheme: this protective cover is to be made of nut, loam cake and lower cover that insulating material is made, the threads engaged of the screw of nut and transformer Wiring terminal, the degree of depth of screw is less than the thickness of nut, loam cake and lower cover middle part are equipped with the through hole that can be enclosed within on the transformer Wiring terminal, loam cake and lower cover are buckled together, and middle formation can be held the cavity of lead and tie lines device, also are provided with the opening that passes through for lead in a side of cavity, nut and loam cake or under cover, also be provided with locking device.
This protective cover is in opening one side of passing through for lead, also is provided with to stretch out and downward-sloping Wire sheath.
Said locking device can be to be connected in the lead sealing line that covers on the nut respectively.
The transformer Wiring terminal protective cover that adopts such scheme to make, can be installed in easily on the Wiring terminal, and reached the purpose of anti-electricity-theft, anti-short circuit, its ammeter box can be removed lower, thereby avoided the inconvenience of tabling look-up and the drawbacks such as seepage of transformer, its cost only is about 1/5th of an original device.
Introduce an embodiment below in conjunction with accompanying drawing.
Fig. 1 is the main pseudosection of present embodiment, and Fig. 2 is its vertical view.
As seen from the figure, this protective cover is to be made of nut (1), loam cake (2), lower cover (3), all has through hole in the middle of the upper and lower covers.High-low pressure insulating sleeve (5) is arranged above the transformer upper end cover (6) among the figure, and Wiring terminal (4) stretches out from sleeve pipe (5).When protective cover is installed, can place on the sleeve pipe (5), and then wire clamp (7) and lead (8) are tied earlier along Wiring terminal (4) cover down lower cover (3).Put loam cake (2) again, lead (8) stretches out from protective cover opening (9).On opening (9), be provided with Wire sheath (10), can prevent that rainwater from entering protective cover.On loam cake (2), tighten with nut (1) and Wiring terminal.Then, again the protective cover between two Wiring terminals is connected with lead sealing line (12) and seal.And then sealing the installation exercise of promptly having finished protective cover with lead sealing between nut (1) and the loam cake (2).Because this protective cover has played anti-electricity-theft effect, so the table case can be located at lower position, transformer below.The bolt of transformer of can having avoided like this removing stage makeup and costume causes seepage, has brought safety and convenient for the personnel of tabling look-up again.
Claims (3)
1, a kind of transformer Wiring terminal protective cover, it is characterized in that: this protective cover is the nut of being made by insulating material (1), loam cake (2) and lower cover (3) constitute, threads engaged on the screw of nut (1) and the transformer Wiring terminal (4), the degree of depth of screw is less than the thickness of nut (1), loam cake (2) and lower cover (3) middle part are equipped with the through hole that can be enclosed within on the transformer Wiring terminal, loam cake (2) and lower cover (3) are buckled together, middle formation can be held the cavity of lead (8) and tie lines device (7), side at cavity also is provided with the opening (9) that passes through for lead, nut and loam cake or under cover, also be provided with locking device.
2, a kind of transformer Wiring terminal protective cover according to claim 1 is characterized in that: in opening (9) one sides of passing through for lead, also be provided with and stretch out and downward-sloping Wire sheath (10).
3, a kind of transformer Wiring terminal protective cover according to claim 1 is characterized in that: said locking device can be the lead sealing line that is connected in respectively on nut (1), the loam cake (2).
