Description

A kind of insulation protection structure of transformer coil lead-in wire
Technical field
The utility model belongs to transformer technology field, relates to the insulation protection structure of a kind of transformer coil lead-in wire.
Background technology
Transformer is the visual plant in industrial and mining enterprises and civil buildings power supply-distribution system.Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core.Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing etc.Wherein, usually outwards lead-out wires of coil is led to, for connecting external power system in primary coil and secondary coil.
As Chinese patent [application number: 200920266301.3; Authorization Notice No. CN201576538 U] disclose combined transformer and comprise switching apparatus cases and transformer-cabinet, transformer oil is had in transformer, device body is immersed in the fuel tank of transformer oil, device body comprises iron core, around the coil on iron core and transformer lead, tap and the transformer lead of coil adopt cold-pressed joint to be connected.
In prior art, during transformer assembling, every root of coil all needs after going between and having connected on this lead-in wire, to wrap up very thick high density insulation crimped paper, to ensure the insulation between lead-in wire.Because lead-in wire in prior art needs to be welded to connect with the exit of coil, now, stripping of insulatin crimped paper is needed to complete welding, again wrap up with insulation crimped paper more afterwards, operate and waste time and energy, and due to number of leads more, thus cause the packaging efficiency of transformer lower.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the insulation protection structure of a kind of transformer coil lead-in wire, and the technical problem that the utility model solves how to improve the packaging efficiency of transformer.
The purpose of this utility model realizes by following technical proposal: a kind of insulation protection structure of transformer coil lead-in wire, described transformer comprises coil, be positioned at the upper clamping piece above coil, lead-in wire and lead-in wire copper bar, described lead-in wire is enclosed with insulating paper, described coil have several wiring exits, one end of described lead-in wire is connected with wiring exit, the other end of described lead-in wire is connected with lead-in wire copper bar, it is characterized in that, described insulation protection structure comprises spiral cover in a tubular form, described spiral cover is set in outside described insulating paper, described spiral cover is positioned at described lead-in wire one end near described coil, the length of described spiral cover is greater than the length of described wiring exit.
Be different from prior art coil to need to realize insulation protection by manual wrap insulate paper with lead-in wire junction, the operation principle of the insulation protection structure of this transformer coil lead-in wire is: be sleeved on lead-in wire by adopting the spiral of tubulose and realize insulation protection with the junction of coil, only need cut one section of spiral cover by actual demand is set on lead-in wire, move spiral cover to junction again, lead-in wire and wiring exit are completely wrapped, just can play the effect of insulation protection, simple to operate, greatly reduce labour intensity and the operating time of workman, thus improve the packaging efficiency of high transformer.
In the insulation protection structure of above-mentioned transformer coil lead-in wire, the junction of described lead-in wire and described wiring exit is enclosed with insulating tape, and described insulating tape is positioned at spiral cover.By arranging the insulation effect of the favourable further reinforced leads of insulating tape and coil junction.
In the insulation protection structure of above-mentioned transformer coil lead-in wire; described spiral overlaps between upper clamping piece and coil; described upper clamping piece is provided with wire fixture; described wire fixture comprises the cardboard of a slice doubling; the two ends of described cardboard lean and are fixed by screws on upper clamping piece; the fold position of described cardboard has cavity, described cardboard also has the Wire channel in building running through described cavity up and down, and described lead-in wire is located in described Wire channel in building.Wire channel in building on cardboard plays the effect of location, can retrain the installing space of lead-in wire, prevents transformer from producing with other parts in moving process and interferes.
In the insulation protection structure of above-mentioned transformer coil lead-in wire, be equipped with waddy in described cavity, described waddy is arranged with strap, described lead-in wire is tightened by strap and is fixed on waddy.When transformer runs, due to the effect of electromagnetic force, going between may produce vibration in insulating paper, is fixed on waddy by lead-in wire by strap, prevents and causes insulating paper to gall because lead-in wire vibration, avoiding lead-in wire and producing and leak electricity.
Alternatively; in the insulation protection structure of above-mentioned transformer coil lead-in wire; described spiral overlaps between upper clamping piece and coil; described upper clamping piece is provided with wire fixture; described wire fixture comprises insulation fixing plate; described insulation fixing plate has bores a hole with several, and described lead-in wire is located in described perforation.During installation, the lead-in wire that only need spiral be had to overlap cover, through perforation, just can realize the fixing, simple to operation of lead-in wire.
Compared with prior art; the insulation protection structure of this transformer coil lead-in wire has the following advantages: the mode of this transformer by adopting sheathed spiral to overlap at lead-in wire with the junction of coil; instead of the mode manually adding bag insulating paper; simple to operation; reduce the labour intensity of installation time and workman, improve the packaging efficiency of transformer.
