Abstract
The invention provides a kind of all-insulation transformer, comprise porcelain vase, primary connection end and secondary connection end that casing and cabinet exterior are arranged, described once, secondary connection end is connected with outlet cable respectively, cabinet exterior is provided with the pedestal I of insulative water-proof material cast, the line place of porcelain vase, primary connection end and primary connection end and outlet cable is fixed in pedestal I by cast, pedestal I is sleeved in metal shell, metal shell is weldingly fixed on casing, and the cable outlet end of metal shell is provided with sealing ring and blind flange; The line place of the porcelain vase of transformer of the present invention, primary connection end and primary connection end and outlet cable is all fixed in pedestal by cast, make the live part of high pressure level and the external world completely isolated, when secondary connection end is also closed in metal shell or when being fixed in pedestal by cast, all live parts of transformer are all isolated from the outside, reach the effect that two-stage live part all realizes totally-enclosed all insulation, use more safe and reliable.
Description
Technical field
The present invention relates to a kind of transformer, particularly a kind of transformer that can realize all insulation.
Background technology
Existing transformer exposes due to high pressure primary connection end, often high pressure electric shock accidents can occur, especially in city; The live part gum cover of high pressure level entangles by people for the sake of security, even if but like this, still there is the seam crossing that some are tiny, if it is all breakneck for touching because of carelessness, meanwhile, moist and drench with rain, the situation such as infiltration all can bring potential safety hazard.
Summary of the invention
The all-insulation transformer that the invention provides a kind of waterproof, protection against the tide and seal.
The present invention solves the technical scheme that its problem adopts:
A kind of all-insulation transformer, comprise porcelain vase, primary connection end and secondary connection end that casing and cabinet exterior are arranged, described once, secondary connection end is connected with outlet cable respectively, it is characterized in that: the pedestal I described cabinet exterior being provided with the cast of insulative water-proof material, the line place of described porcelain vase, primary connection end and primary connection end and outlet cable is fixed in described pedestal I by cast.
As optimal way of the present invention, the line place of described secondary connection end and secondary connection end and outlet cable is poured into a mould to be fixed in pedestal II that insulative water-proof material pours into a mould; Described pedestal II is sleeved in metal shell, and metal shell is weldingly fixed on casing; The cable outlet end of described metal shell is provided with sealing ring and blind flange.
The invention has the beneficial effects as follows: the line place of the porcelain vase of transformer, primary connection end and primary connection end and outlet cable is all fixed in pedestal I by cast, make the live part of transformer high-voltage grade and the external world completely isolated, all insulation of this high-pressure side also reaches good waterproof, protection against the tide and sealing effectiveness while removal potential safety hazard; When the line place of secondary connection end and secondary connection end and outlet cable is all closed in metal shell or when being fixed in pedestal by cast, all live parts of transformer are all isolated from the outside, reach the effect that two-stage live part all realizes totally-enclosed all insulation, use more safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the stereogram of Fig. 1;
Fig. 3 is the structural representation of another embodiment of the present invention.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of all-insulation transformer, comprise porcelain vase 2, primary connection end 3 and secondary connection end 4 that casing 1 and casing 1 outer wall are arranged, described once, secondary connection end 3,4 is connected with outlet cable 7 respectively, described cabinet exterior is provided with the pedestal I51 of insulative water-proof material cast, described porcelain vase 2, primary connection end 3 and primary connection end 3 is fixed in described pedestal I51 with the line place of outlet cable 7 by cast, described pedestal I51 is sleeved in metal shell I61, and metal shell I61 is weldingly fixed on casing 1.
As the preferred embodiments of the present invention, described secondary connection end 4 and secondary connection end 4 are all fixed in pedestal II52 by cast with the line place of outlet cable 7, and described pedestal II52 is sleeved in metal shell II62, and metal shell II62 is weldingly fixed on casing 1.
Described pedestal I51 and pedestal II52 adopts insulative water-proof material pitch or silicon rubber cast to form, metal shell I61 and metal shell II62 both can as die cavity when pitch or silicon rubber cast, can be weldingly fixed on casing 1 again, the connection between pedestal and casing be sealed more reliable and more stable; Certainly, also can at the housing of other materials casting insulated waterproof material electric device be sealed and be fixed on casing.The top of metal shell I61 is provided with the entrance that blind flange 8 is poured into a mould as insulative water-proof material, by housings close after casting complete.
Cable outlet end is provided with sealing ring 9 and blind flange 8, and when can prevent from the one hand pouring into a mould, liquid spills from leading-out terminal, can also play dual-seal and moisture-proof role on the other hand after liquid solidifies to the electric device of enclose inside.
With reference to Fig. 3, another kind of embodiment of the present invention: described secondary connection end 4 and secondary connection end 4 are all encapsulated in metal shell II62 with the line place of outlet cable 7, metal shell II62 is weldingly fixed on casing 1, and the cable outlet end of metal shell II62 is provided with sealing ring 9 and blind flange 8 realizes sealed damp-proof.
The line place of transformer porcelain vase of the present invention, primary connection end and primary connection end and outlet cable is all fixed in pedestal by cast, make the high pressure level live part of transformer and the external world completely isolated, all insulation of this high-pressure side also reaches good waterproof, protection against the tide and sealing effectiveness while removal potential safety hazard; When the line place of secondary connection end and secondary connection end and outlet cable is all closed in metal shell or when being fixed in pedestal by cast, all live parts of transformer are all isolated from the outside, reach the effect that two-stage live part all realizes totally-enclosed all insulation, use more safe and reliable.
