Abstract
The utility model provides an electric larceny-proof outdoor mutual inductor, which includes a shell. The shell is provided with a secondary coil, a core is arranged between the two secondary coils, a through hole is provided at middle part of the shell, a metal sheet is installed in the through hole, an insulator is provided between the metal element and the secondary coil, a lead-out wire provided of the secondary coil and a lead-out wire of the metal sheet are cast into the insulator, the other ends of the three lead-out wires are led out form the outer end surface, the three lead-out wires are all packed inside of a sleeve tube, on end of the sleeve tube is cast into the isolator. The utility model has the advantages of effectively preventing electricity theft behaviors ,no mater what kinds of mode adopted to steal electricity are the destructive behaviors, which are easily detected, the device has good performance for electric larceny-proof; due to good performance of sun-screening of the shell, the device can prevent sunlight from directing to U-type plate on the shell to make long working life of the elements in the shell; with good performance of anti-humidity and anti-dust; accurate metering and long working life etc.
Description
Technical field
The utility model relates to electric elements, is the special-purpose instrument transformer of a kind of anti-fraudulent use of electricity type outdoor transformer.
Background technology
The applicant is in the special-purpose instrument transformer of the outdoor transformer of application in 2002, though more advantage is arranged, find that in actual applications still there is deficiency in it: anti-electricity-theft performance is still owed fully, stealing electricity phenomenon still takes place sometimes be difficult for being found.In addition, because sun direct projection housing easily makes the instrument transformer heating, influence the useful life of each parts.The anti-electricity-theft instrument transformer of report is arranged, but its structure and manufacture method complexity can't form product and use in practice.
Summary of the invention
The purpose of this utility model is, provides a kind of anti-fraudulent use of electricity type outdoor transformer special-purpose instrument transformer, makes it have thief-proof good electrical property, advantages such as low cost of manufacture.
The utility model is in order to finish goal of the invention, following technical scheme is provided: it comprises housing, secondary coil is installed in the housing, between two secondary coils, iron core is installed, through hole is offered at the housing middle part, through hole one end is installed sheet metal, between housing and the secondary coil insulator is set, the lead-out wire of secondary coil and be cast in the insulator with the lead-out wire of sheet metal, article three, the other end of lead-out wire is drawn in the outer face of insulator, article three, lead-out wire is covered by in the sleeve pipe, and sleeve pipe one end is cast in the insulator.The housing profile is the U type, and the round boss of the oriented outer lug of closed bottom end of U type has an inside annular groove between round boss and the U type closed bottom end.Insulator is offered the hole on the outer face, and the diameter in hole is greater than the external diameter of sheet metal.The outer face of insulator is lower than the outer face of housing.
Advantage of the present utility model is: can prevent effectively that electricity filching behavior from taking place, no matter taking any way stealing all is destructive behaviors, all easily is found thief-proof good electrical property; Because the sun-proof performance of housing is good, has avoided sun direct irradiation on the U of housing type bottom surface, prolonged the useful life of enclosure interior device; Moisture resistance and dust tightness are good; Accurate measurement, long service life etc.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
2 is housings among the figure, the contrast drawings and Examples, the utility model is described further: secondary coil 4 and secondary coil 12 are installed in the housing 2, iron core 5 is installed between secondary coil 4 and secondary coil 12, through hole 1 is offered at housing 2 middle parts, through hole 1 one ends are installed sheet metal 11, between housing 2 and the secondary coil 4 insulator 3 is set, the lead-out wire 8 of secondary coil and 7 and the lead-out wire 6 of sheet metal 11 be cast in the insulator 3, article three, the other end of lead-out wire is drawn in the outer face of insulator 3, article three, lead-out wire is covered by in the sleeve pipe 9, and sleeve pipe 9 one ends are cast in the insulator 3.The length that the other end extends is provided with as required, housing 2 profiles are the U type, in order to prevent sun direct projection, reduce housing 2 temperature and be provided with round boss 13 to outer lug in the closed bottom end of U type, an inside annular groove 14 is arranged between round boss 13 and the U type closed bottom end.Insulator is offered hole 10 on 3 outer faces, and the diameter in hole 10 is convenient to install sheet metal 11 greater than the external diameter of sheet metal 11, and is easy to fix, and for the ease of instrument transformer is installed, makes the outer face of insulator 3 be lower than the outer face of housing 2.Housing 2 of the present utility model adopts ceramic making, and insulator adopts resin material to make.
