Specific embodiment

The utility model provides a kind of high-voltage safety transformer, a kind of high-voltage safety transformer, including casing 1, case lid 2 And the radiator 3 on casing, radiator 3 contacts with casing 1, the heat derives in casing 1 can be scattered, it is to avoid Occurs temperature accumulation in casing 1.Case lid 2 is arranged in the top of casing 1, casing 1 and is provided with Transformer Winding 4, pacifies on case lid 2 Equipped with bushing 5.

High-voltage safety transformer is also configured with power-off alarm and overload alarm, and power-off alarm and overload alarm are matched somebody with somebody The megaphone being arranged in casing is equipped with, alarm can be configured with corresponding detection circuit and controller, and by amplifying Loudspeaker amplify alarm signal.

High-voltage safety matched transformer is equipped with power-off alarm and overload alarm, and power-off alarm and overload alarm are configured There is the megaphone being arranged in casing, audible alarm is sent by megaphone.Power-off alarm is able to detect that transformation Device operation circuit voltage disappears or disconnects and send immediately alarm signal, and power-off alarm can be comprising power-off signal sampling electricity Road and cut-offing alarming circuit, wherein, power-off signal sample circuit is connected to step down side two by the coil of auxiliary reclay Constitute between root phase line or a phase line and a neutral conductor.Overload alarm can check transformer electricity in running Whether stream voltage transships, and overload-alarm is sent when overload occurs.

Transformer Winding 4 includes the winding mold 41 of open column shape, is enclosed with the first metal lenticular wire 42 of insulating barrier and is enclosed with Second metal lenticular wire 43 of insulating barrier；Wherein, multiple winding zones, the first gold medal are sequentially formed with the length direction of winding mold 41 The equal continuous winding of 42 and second metal lenticular wire of category lenticular wire 43 is on winding mold；One of them of two winding zones of arbitrary neighborhood is twined On region, the first metal lenticular wire is wrapped on winding mold as internal layer, and the second metal lenticular wire is wrapped in the first gold medal as outer layer Outside category lenticular wire, in other in which winding zone, the second metal lenticular wire is wrapped on winding mold as internal layer, and the first metal lenticular wire It is wrapped in outside the second metal lenticular wire as outer layer.The first metal lenticular wire and the second metal are so converted in different winding zones The inside and outside layer relation of lenticular wire is identical so as to ensure the length of the first metal lenticular wire and the second metal lenticular wire on winding mold, then the The resistance of one metal lenticular wire and the second metal lenticular wire is identical, so as to completely avoid because of the first metal lenticular wire and the second metal lenticular wire Resistance it is different and produce the generation of substantial amounts of heat.

For example, in each winding zone, the first metal lenticular wire and the second metal lenticular wire are twined towards same winding direction Around, and being bordered by position between two winding zones of arbitrary neighborhood, the first metal lenticular wire and the second metal lenticular wire hasp, The first metal lenticular wire after hasp is interchangeable with one another with the ectonexine position of the second metal lenticular wire.Such canoe is being wrapped over Without the need for consideration the first metal lenticular wire of conversion and the winding direction of the second metal lenticular wire in journey, can effectively accelerate to wind speed.

For example, in each winding zone, the winding direction of the winding direction of the first metal lenticular wire and the second metal lenticular wire Conversely, and being bordered by position between two winding zones of arbitrary neighborhood, the first metal lenticular wire and the second metal lenticular wire phase Mutual hasp and reverse-winding.Such canoe more can efficiently convert the first metal lenticular wire and the second metal lenticular wire Inside and outside layer position, can be laborsaving.

Bushing 5 includes sleeve body and silicon rubber shirt rim 51, and sleeve body includes conductive part 52 and be arranged on to lead Pour mass 53 outside electric portion 52, the outer surface of pour mass 53 is provided with flange 54, and silicon rubber shirt rim is wrapped in pour mass upper flange And the position on the right side of flange, the position on the left of pour mass upper flange is stretched into and by flange screw by the tank wall perforate of casing Fixed, the cast between flange and conductive part is provided with vivo metal net mask 55, and flange is provided with symmetrical two screw 56, and Screw is electrically connected by wire with metal net mask, and one layer of cushion 57 is additionally provided between conductive part and pour mass.Bushing Can be that in a mold vacuum technology pours into epoxy resin mixed glue by conductive part, cushion and metal net mask, be heating and curing Shaping, pour mass can be made of epoxy resin mixed glue.

Cast between flange 54 and conductive part 52 arranges in vivo a metal net mask 55, so can effectively solve The problem that flange non-uniform electric is arrived, it is to avoid in industrial frequency withstand voltage test or the flashover of actually used middle appearance, from And cause whole casing safety performance higher；And a cushion, such conductive part are set between conductive part and pour mass Be powered expansion after do not interfere with and pour mass combination, and then cause operational reliability it is higher；Again because being provided with flange Screw, and the screw electrically connected by wire with metal net mask, but because whether metal net mask can sense in conductive part It is powered, so connects at screw and be directly connected on an electrification display, whether powered can thus detects conductive part.

In an optimal enforcement example of the present utility model, bolt hole is provided with casing 1 and case lid 2, both are by fixing Bolt connection.The exterior base of casing 1 is provided with the bracing frame 6 for supporting box；The side wall of casing is provided with hangers 7, and hangers 7 is just In lifting transformer.
