Description
Technical field
The present invention relates to a kind of transformer, specifically a kind of transformer with waterproof and anti-false wiring function.
Background technology
Voltage transformer is the main components in switch cubicle, in order to realize voltage measurement or electic protection, general mutual inductance
The second part of device two is all to use binding post, is then connected using Wiring nose, electric wire, finally guided in instrument.In recent years with
Transformer industry development, a large amount of outdoor mutual inductors in use, because the technical ability of workmen is very different, often result in mutual inductance
Device second loop return wiring mistake.Such as voltage transformer short circuit, current transformer open circuit etc..Cause transformer explosion, cause
Very bad influence.Very big inconvenience is caused to user.By site inspection, it is substantially because mutual inductor interstar connection mistake（It is secondary
Short circuit or open circuit）Caused by accident.Brought to transformer manufacturing firm, switch cubicle manufactory, electric power system and user very big
Inconvenience.
For the content of the invention the invention provides a kind of compact-sized, sealing, insulation are stable, take into account waterproof and anti-false wiring
Transformer.
The technical solution adopted by the present invention is：A kind of transformer with waterproof and anti-false wiring function, including it is housing, molten
Disconnected device terminal, iron core, primary winding, more than one secondary coil, it is characterised in that：The lower housing portion side wall is provided with opening court
Under terminal box, aviation socket directed downwardly is provided with terminal box, aviation socket is secondary in terminal box internal wiring connection more than one
Both ends of coil and through epoxy resin sealed terminal box, are configured with the aviation plug of connecting cable on aviation socket.
The aviation plug is provided with avoiding misinsertion key or mistake proofing slot, and aviation socket is provided with the mistake proofing of corresponding aviation plug
Slot or avoiding misinsertion key.
The present invention sets aviation socket in terminal box, matches aviation plug grafting, effectively can prevent in site operation
Because secondary connection misconnection causes the accident situation, while the tool-free installation of two second part is realized, need to only be operated with hand and can be achieved,
Exempt the secondary part field wiring of transformer, scene, which only needs to carry, plugs together aviation plug on aviation socket, tightens air plug spiral shell
Mother, site operation is greatlyd save from the engineering time of lead-out wire at transformer secondary terminals.Epoxy resin in terminal box
Waterproof is sealed, itself waterproof of additional aviation plug, socket, forms dual waterproofing protection, reduces outdoor because waterproof measure is handled
Transformer burns caused by improper.The transformer is easy for installation, security is higher, and using effect is obvious, caused by reduction accident
Schedule delays and the wasting of resources of man power and material.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is Fig. 1 left views.
In figure：Housing 1, fuse terminal 2, iron core 3, secondary coil 4, terminal box 5, aviation socket 6, aviation plug 7, electricity
Cable 8.
Embodiment
It is described further below in conjunction with drawings and examples.
Fig. 1, shown in 2：A kind of transformer with waterproof and anti-false wiring function includes housing 1, fuse terminal 2, iron
The heart 3, primary winding, more than one secondary coil 4, terminal box 5, the lower sides of housing 1 are provided with downward opening terminal box 5, connect
Aviation socket 6 directed downwardly is provided with line box 5, aviation socket 6 connects the both ends of more than one secondary coil in terminal box internal wiring
And through epoxy resin sealed terminal box, the aviation plug 7 of connecting cable 8 is configured with aviation socket 6.
Improved on the basis of above-described embodiment, settable avoiding misinsertion key or mistake proofing slot on aviation plug, on aviation socket
The mistake proofing slot or avoiding misinsertion key of settable corresponding aviation plug.
Claims (2)
1. a kind of transformer with waterproof and anti-false wiring function, including housing, fuse terminal, iron core, primary winding, one
Secondary coil more than, it is characterised in that：The lower housing portion side wall is provided with downward opening terminal box, and court is provided with terminal box
Under aviation socket, aviation socket terminal box internal wiring connect more than one secondary coil both ends and sealed through epoxy resin
Terminal box, the aviation plug of connecting cable is configured with aviation socket.
2. a kind of transformer with waterproof and anti-false wiring function according to claim 1, it is characterized in that：The aviation
