Description

Totally-enclosed electric shock-free oil type transformer

Technical Field

The utility model belongs to the power supply and distribution field especially relates to a totally closed electric shock oil formula transformer that exempts from.

Background

At present, oil transformers are all of an upper-inlet and upper-outlet type structure, a high-voltage side is generally led in an overhead mode through a drop-out fuse and an isolating switch, and a low-voltage side is led to users through cables. A special transformer chamber is required to be arranged on a common box-type transformer, so that the occupied area is large, and the construction cost is high; the overhead transformer substation area has potential safety hazards due to the fact that high-voltage lead sleeves and low-voltage lead sleeves of the transformer are exposed.

Disclosure of Invention

The utility model aims at providing a but realize full touch's totally closed electric shock free oil formula transformer on the basis that rational in infrastructure, safe waterproof, area are few, occupation space is little, does not change current oil formula transformer electrical component.

The technical scheme of the utility model is that: it includes the transformer box, the footing, the fin, the oil level gaugember, the pressure gauge, the thermometer, high pressure inlet wire terminal, low pressure outlet wire terminal and oily formula transformer electrical components etc. constitute, the high pressure protective housing who installs high pressure inlet wire terminal and the low pressure protective housing who installs low pressure outlet wire terminal have been add on the lateral wall of transformer box, and high pressure sealed lid has been set up at high pressure protective housing terminal surface, low pressure protective housing terminal surface has set up low pressure sealed lid, sealed lid passes through the bolt and forms the totally enclosed space at protective housing terminal surface, high-low pressure business turn over line lead wire all penetrates from high-low pressure protective housing bottom.

Furthermore, the low-voltage protective shell and the high-voltage protective shell are both made of metal materials and are welded with the transformer box body into a whole, so that the incoming line and outgoing line binding posts of the transformer are installed in the fully-closed metal waterproof high-reliability grounding protective shell, the purpose of full-closed touchability is achieved, and the occurrence of electric shock accidents is avoided.

The utility model has the advantages that: on the premise of not changing the electrical components of the existing transformer, only the structure of the transformer shell is changed, and the high-voltage incoming wiring terminal and the low-voltage outgoing wiring terminal of the transformer are both installed in the totally-enclosed metal waterproof high-reliability grounding protective shell integrated with the transformer box body through spot welding, so that the purpose of avoiding electric shock is realized, and waterproof and full sealing can be realized only by adding a sealing ring between the sealing cover and the protective shell. The novel water-proof and waterproof combined power transmission cable has the advantages of reasonable structure, safety, water resistance, small occupied area, small occupied space and the like, and can be widely applied to the construction of various power transmission network cable transformer areas.

The present invention will be further described with reference to the accompanying drawings.

In the figure: the transformer box comprises a transformer box body 1, a bottom foot 2, a radiating fin 3, an oil level gauge 4, a pressure gauge 5, a thermometer 6, a high-voltage wire inlet binding post 7, a low-voltage wire outlet binding post 8, a low-voltage protective shell 9, a high-voltage protective shell 10, a low-voltage sealing cover 11 and a high-voltage sealing cover 12.

Detailed Description

As shown in the figure, totally closed exempt from to get an electric shock oil formula transformer comprises transformer box 1, footing 2, fin 3, oil level gaugember 4, pressure gauge 5, thermometer 6, high-pressure inlet wire terminal 7, low pressure terminal 8 and the oily formula transformer electrical component etc. of being qualified for the next round of competitions, set up fin 3 on two lateral walls around transformer box 1, high pressure inlet wire terminal 7 and low pressure terminal 8 of being qualified for the next round of competitions set up respectively on the corresponding outer wall in transformer box 1 left and right sides to set up low pressure protective housing 9 on the left lateral wall that sets up low pressure terminal 8 of being qualified for the next round of competitions, set up high pressure protective housing 10 at the right lateral wall that sets up high pressure terminal 7 of being qualified for the next round of competitions. The low-voltage protective shell 9 and the high-voltage protective shell 10 are both made of metal materials and welded with the transformer box body 1 to form a whole, the high-voltage sealing cover 12 is arranged on the end face of the high-voltage protective shell 10, the low-voltage sealing cover 11 is arranged on the end face of the low-voltage protective shell 9, and high-voltage and low-voltage incoming and outgoing line leads penetrate through the bottom of the high-voltage and low-voltage protective shell through waterproof joints. Implement the utility model discloses in the time, at first open the sealed lid 12 of the sealed lid of the totally closed high pressure protective housing 10 terminal surface high pressure that transformer box 1 both sides were add and the sealed lid 11 of the sealed lid of 9 terminal surfaces low pressure of low pressure protective housing to in the bottom surface trompil of protective housing penetrates protective housing with high low pressure lead wire respectively through water joint, with through the insulating full touch electrical technology preparation high pressure inlet wire terminal 7 of standard and low pressure outlet wire terminal 8 link to each other, but seal lid 12 of high pressure and the sealed lid 11 of low pressure through the bolt (the high local installation of waterproof requirement seals the circle) be fixed in the box and seal again. Because the protective shells at two sides are not made of metal materials and are welded with the transformer box body 1 into a whole, the incoming wire and outgoing wire binding posts of the transformer are installed in the fully-closed metal waterproof high-reliability grounding protective shell, the problems of potential safety hazards caused by the fact that high and low voltage lead sleeves of a common oil type transformer are exposed are solved, the transformer has the advantages of being reasonable in structure, safe and waterproof, small in occupied area, small in occupied space and the like, the purpose of avoiding electric shock can be achieved by changing the structure of the transformer shell on the premise that the electrical part of the existing oil type transformer is not changed, and the transformer can be widely applied to construction of various power transmission network line transformer areas.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
